  • Why are heart attacks less deadly then they used to be

    Why are heart attacks less deadly then they used to be

    A day before my 47th birthday last month, I took the subway to Manhattan’s Upper East Side for a coronary artery calcium scan (CAC).

    For those who haven’t entered the valley of middle age, a CAC is a specialized CT scan that looks for calcium deposits in the heart and its arteries. Unlike in your bones, having calcium in your coronary arteries is a bad thing, because it indicates the buildup of plaque comprised of cholesterol, fat, and other lovely things. The higher the calcium score, the more plaque that has built up — and with it, the higher the risk of heart disease and even heart attacks.

    A couple of hours after the test, I received a ping on my phone. My CAC score was 7, which indicated the presence of a small amount of calcified plaque, which translates to a “low but non-zero cardiovascular risk.” Put another way, according to one calculator, it means an approximately 2.1 percent chance of a major adverse cardiovascular event over the next 10 years.

    2.1 percent doesn’t sound high — it’s a little higher than the chance of pulling an ace of spades from a card deck — but when it comes to major adverse cardiovascular events, 2.1 percent is approximately 100 percent higher than I’d like. That’s how I found myself joining the tens of millions of Americans who are currently on statin drugs, which lower levels of LDL cholesterol (aka the “bad” cholesterol).

    I didn’t really want to celebrate my birthday with a numerical reminder of my creeping mortality. But everything about my experience — from the high-tech calcium scan to my doctor’s aggressive statin prescription — explains how the US has made amazing progress against one of our biggest health risks: heart disease, and especially, heart attacks.

    A dramatic drop in heart attack deaths

    A heart attack — which usually occurs when atherosclerotic plaque partially or fully blocks the flow of blood to the heart — used to be close to a death sentence. In 1963, the death rate from coronary heart disease, which includes heart attacks, peaked in the US, with 290 deaths per 100,000 population. As late as 1970, a man over 65 who was hospitalized with a heart attack had only a 60 percent chance of ever leaving that hospital alive.

    A sudden cardiac death is the disease equivalent of homicide or a car crash death. It meant someone’s father or husband, wife or mother, was suddenly ripped away without warning. Heart attacks were terrifying.

    Yet today, that risk is much less. According to a recent study in the Journal of the American Heart Association, the proportion of all deaths attributable to heart attacks plummeted by nearly 90 percent between 1970 and 2022. Over the same period, heart disease as a cause of all adult deaths in the US fell from 41 percent to 24 percent. Today, if a man over 65 is hospitalized with a heart attack, he has a 90 percent chance of leaving the hospital alive.

    By my calculations, the improvements in preventing and treating heart attacks between 1970 and 2022 have likely saved tens of millions of lives. So how did we get here?

    In 1964, the year after the coronary heart disease death rate peaked, the US surgeon general released a landmark report on the risks of smoking. It marked the start of a decades-long public health campaign against one of the biggest contributing factors to cardiovascular disease.

    That campaign has been incredibly successful. In 1970, an estimated 40 percent of Americans smoked. By 2019, that percentage had fallen to 14 percent, and it keeps declining.

    The reduction in smoking has helped lower the number of Americans at risk of a heart attack. So did the development and spread in the 1980s of statins like I’m on now, which make it far easier to manage cholesterol and prevent heart disease. By one estimate, statins save nearly 2 million lives globally each year.

    When heart attacks do occur, the widespread adoption of CPR and the development of portable defibrillators — which only began to become common in the late 1960s — ensured that more people survived long enough to make it to the hospital. Once there, the development of specialized coronary care units, balloon angioplasty and artery-opening stents made it easier for doctors to rescue a patient suffering an acute cardiac event.

    Our changing heart health deaths

    Despite this progress in stopping heart attacks, around 700,000 Americans still die of all forms of heart disease every year, equivalent to 1 in 5 deaths overall.

    Some of this is the unintended result of our medical success. As more patients survive acute heart attacks and life expectancy has risen as a whole, it means more people are living long enough to become vulnerable to other, more chronic forms of heart disease, like heart failure and pulmonary-related heart conditions. While the decline in smoking has reduced a major risk factor for heart disease, Americans are in many other ways much less healthy than they were 50 years ago. The increasing prevalence of obesity, diabetes, hypertension, and sedentary behavior all raise the risk that more Americans will develop some form of potentially fatal heart disease down the line.

    Here, GLP-1 inhibitors like Ozempic hold amazing potential to reduce heart disease’s toll. One study found that obese or overweight patients who took a GLP-1 inhibitor for more than three years had a 20 percent lower risk of heart attack, stroke, or death due to cardiovascular disease. Statins have saved millions of lives, yet tens of millions more Americans could likely benefit from taking the cholesterol-lowering drugs, especially women, minorities, and people in rural areas.

    Lastly, far more Americans could benefit from the kind of advanced screening I received. Only about 1.5 million Americans received a CAC test in 2017, but clinical guidelines indicate that more than 30 million people could benefit from such scans.

    Just as it is with cancer, getting ahead of heart disease is the best way to stay healthy. It’s an astounding accomplishment to have reduced deaths from heart attacks by 90 percent over the past 50-plus years. But even better would be preventing more of us from ever getting to the cardiac brink at all.

    Vizsla Silver Corp.’s (TSE:VZLA) market cap touched CA$1.4b last week, benefiting both individual investors who own 59% as well as institutions

    • The considerable ownership by individual investors in Vizsla Silver indicates that they collectively have a greater say in management and business strategy

    • The top 25 shareholders own 36% of the company

    • Insiders have been selling lately

    This technology could replace computers: discover the 20 stocks are working to make quantum computing a reality.

    To get a sense of who is truly in control of Vizsla Silver Corp. (TSE:VZLA), it is important to understand the ownership structure of the business. And the group that holds the biggest piece of the pie are individual investors with 59% ownership. In other words, the group stands to gain the most (or lose the most) from their investment into the company.

    While individual investors were the group that reaped the most benefits after last week’s 5.6% price gain, institutions also received a 34% cut.

    Let’s delve deeper into each type of owner of Vizsla Silver, beginning with the chart below.

    TSX:VZLA Ownership Breakdown July 5th 2025

    Institutional investors commonly compare their own returns to the returns of a commonly followed index. So they generally do consider buying larger companies that are included in the relevant benchmark index.

    Vizsla Silver already has institutions on the share registry. Indeed, they own a respectable stake in the company. This suggests some credibility amongst professional investors. But we can’t rely on that fact alone since institutions make bad investments sometimes, just like everyone does. If multiple institutions change their view on a stock at the same time, you could see the share price drop fast. It’s therefore worth looking at Vizsla Silver’s earnings history below. Of course, the future is what really matters.

    We note that hedge funds don’t have a meaningful investment in Vizsla Silver. Our data shows that Sprott Inc. is the largest shareholder with 7.0% of shares outstanding. In comparison, the second and third largest shareholders hold about 4.2% and 3.1% of the stock. In addition, we found that Michael Konnert, the CEO has 0.7% of the shares allocated to their name.

    Our studies suggest that the top 25 shareholders collectively control less than half of the company’s shares, meaning that the company’s shares are widely disseminated and there is no dominant shareholder.

    Researching institutional ownership is a good way to gauge and filter a stock’s expected performance. The same can be achieved by studying analyst sentiments. There are plenty of analysts covering the stock, so it might be worth seeing what they are forecasting, too.

    Heavy rain forecast across Punjab on Ashura

    Listen to article

    A fresh spell of monsoon rains has entered Punjab, with the Pakistan Meteorological Department forecasting heavy showers in Lahore and several other districts across the province on Ashura (Muharram 10).

    The Provincial Disaster Management Authority (PDMA) has issued an alert for possible rainfall on Ashura, warning of intense downpours in Lahore, Rawalpindi, Gujranwala, Gujrat, Sialkot, Sargodha, and Faisalabad.

    Experts have predicted that the current monsoon system could persist until July 10, potentially raising water levels in rivers and streams.

    Rescue 1122 teams have been placed on full alert, while the Disaster Response Force has been instructed to remain fully equipped and ready. Citizens are urged to follow safety precautions and contact the PDMA helpline (1129) in case of emergencies.

    Meanwhile, after a hot and humid day in Lahore, the provincial capital is expected to receive heavy rain with thunder and lightning late at night. Temperatures in the city are forecast to range between 30°C and 37°C.

    The Met Office has warned that rainfall of varying intensity—ranging from light to heavy—is expected in multiple areas of Punjab due to the re-entry of a rain-bearing monsoon system. Strong winds and further downpours are likely to continue in the coming days.

    Residents of Lahore have expressed concern over the slow pace of infrastructure development projects, warning that incomplete work could lead to severe disruptions during heavy monsoon rains.

  • Trump signs sweeping tax and spending cuts into law on Fourth of July

    Trump signs sweeping tax and spending cuts into law on Fourth of July

    Listen to article

    US President Donald Trump signed into law a massive package of tax and spending cuts at the White House on Friday, staging an outdoor ceremony on the Fourth of July holiday that took on the air of a Trump political rally.

    With military jets flying overhead and hundreds of supporters in attendance, Trump signed the bill one day after the Republican-controlled House of Representatives narrowly approved the signature legislation of the president’s second term.

    The bill, which will fund Trump’s immigration crackdown, make his 2017 tax cuts permanent, and is expected to knock millions of Americans off health insurance, was passed with a 218-214 vote after an emotional debate on the House floor.

    “I’ve never seen people so happy in our country because of that, because so many different groups of people are being taken care of: the military, civilians of all types, jobs of all types,” Trump said at the ceremony, thanking House Speaker Mike Johnson and Senate Majority Leader John Thune for leading the bill through the two houses of Congress.

    “So you have the biggest tax cut, the biggest spending cut, the largest border security investment in American history,” Trump said.

    Trump scheduled the ceremony on the South Lawn of the White House for the July 4 Independence Day holiday, replete with a flyover by stealth bombers and fighter jets like those that took part in the recent US strikes on nuclear facilities in Iran. Hundreds of Trump supporters attended, including White House aides, members of Congress, and military families.

    After a speech that included boastful claims about the ascendance of America on his watch, Trump signed the bill, posed for pictures with Republican congressional leaders and members of his cabinet, and waded through the crowd of happy supporters.

    The bill’s passage amounts to a big win for Trump and his Republican allies, who have argued it will boost economic growth, while largely dismissing a nonpartisan analysis predicting it will add more than $3 trillion to the nation’s $36.2 trillion debt.

    While some lawmakers in Trump’s party expressed concerns over the bill’s price tag and its hit to healthcare programs, in the end just two of the House’s 220 Republicans voted against it, joining all 212 Democrats in opposition.

    The tense standoff over the bill included a record-long floor speech by House Democratic Leader Hakeem Jeffries, who spoke for eight hours and 46 minutes, blasting the bill as a giveaway to the wealthy that would strip low-income Americans of federally-backed health insurance and food aid benefits.

    Democratic National Committee Chair Ken Martin predicted the law would cost Republicans votes in congressional elections in 2026.

    “Today, Donald Trump sealed the fate of the Republican Party, cementing them as the party for billionaires and special interests – not working families,” Martin said in a statement. “This legislation will hang around the necks of the GOP for years to come. This was a full betrayal of the American people. Today, we are putting Republicans on notice: you will lose your majority.”

  • How to Tell When It’s More Than Stress

    How to Tell When It’s More Than Stress

    Chances are you don’t realize the impact anxiety can have on guys. Studies continuously show that women are twice as likely as men to be diagnosed with an anxiety disorder–but that doesn’t mean you’re immune.

    Researchers can’t explain the causes of this disparity, but believe guys may feel pressured to exhibit anxious feelings in ways that seem more masculine.

    “I think the biggest thing is men are socialized not to show anxiety,” said Carmen McLean, PhD, a researcher and clinical associate professor at Stanford University’s Department of Psychiatry. “Socializing to show agency and self-efficiency dissuades from showing anxiety.”

    This is one reason anxiety is often accompanied by substance abuse and other “internalizing disorders, ” said McLean. Sometimes these signs can be subtle, meaning it’s especially important to recognize symptoms of anxiety disorders specific to males.

    Some clues—nervousness, dread over impending danger and rapid breathing—are common across gender lines, but these five manifestations of anxiety disproportionately impact men:

    Anxious Men Fear Dating

    Men with social anxiety disorder are more likely to fear dating and are more commonly single, separated or divorced, according to an analysis of survey information from Columbia University.

    “Men are supposed to take the lead in dating,” explained Stefan G. Hofmann, PhD and psychology professor at Boston University who researches anxiety. “The male is the one who is expected to take the first step. That puts them in a performance situation.”

    Even in the age of apps, men are typically the pursuer. On OkCupid, males are three times more likely to send a first message in an opposite-sex exchange. This means constantly offering yourself up for evaluation and rejection–an anxiety-inducing prospect.

    “It’s a challenge for people who don’t like to play that game,”said Hofman.

    Plus, some agonize over being chronically single–with reason–David Ezell, clinical director of Darien Wellness, a psychology clinic in Connecticut, told Men’s Health.

    “Men really benefit from marriage,” Ezell said. “They’re less likely to be sick. They’re less likely to be hospitalized. They’re hospitalized for shorter stays if they are hospitalized.”

    Also, marriage is a status symbol, a sign of “maturation,” said Ezell.

    With so much at risk, dating and bachelorhood are significant sources of stress in men with anxiety.

    Anxious Men May Abuse Alcohol and Drugs

    Men drink and use drugs to relieve anxiety more often than women, according to the same Columbia University study. Research has consistently shown a link between substance abuse and mental health disorders, particularly in men.

    “They are looking for medication,” said Ezell. He explains a glass of booze pairs well with the “I-can-fix-it-myself” attitude associated with masculinity because it doesn’t require medical assistance and may seem like a socially acceptable way to ease stress.

    “Alcohol is a very effective drug,” said Hofmann. “It’s why it’s so popular.”

    Think about college students who “pre-game” by drinking at a dorm or with a small group of friends before going to larger parties. They may not realize it, but this helps manage the anxiety of socializing.

    Guys who forego professional treatment may instead turn to drugs or heavy drinking to cope with anxiety–and this may be a doorway to addiction.

    Anxious Men May Seem Angry

    In some men, anxiety may manifest as rage or anger. “It’s much more acceptable,” said McLean. While women may find support from friends or mental health professionals, guys often let their feelings build up until they hit a breaking point–and then the flood gates open.

    “Because emotions don’t get expressed [by men], because anxiety isn’t expressed in a healthy way, there are busts of anger as a result,” said Ezell. “I think anger is considered decisive.”

    If typical signs of anxiety, like nervousness or fear, are discouraged in men, anger is their only acceptable emotional response.

    Anxious Men Have Strained Relationships

    In another study of survey data from Columbia University, men were more likely than women to experience relationship strain from worrying.

    This could be because women are more likely to have a circle of close friends, whereas men tend to have few confidants who can provide support through emotional distress.

    “Men tend to rely on romantic partners for stress,” said Hofman. This can be a burden, he explained.

    Sociologist Eli J. Finkel further detailed the risk of putting all that psychological dependence on one person in his book, The All-Or-Nothing Marriage. Finkel argued that modern relationships are tense because people seek comfort, growth, purpose, and a host of other needs from romantic partnerships. Prior generations sought comfort in an entire network of family and friends.

    “Marriage for a long time served a set and relatively limited array of different functions for us,” Finkel told the NPR podcast Hidden Brain. “And over time we’ve piled more and more of these emotional and psychological functions.”

    Anxious men might burn out their few outlets (or only outlet) for social support quickly.

    Anxious Men Obsesses Over Status

    Ezell’s practice is located in Darien, Connecticut, a bedroom community for hedge fund managers and Wall Street executives. With a median family income of $208,125, it’s frequently named one of the wealthiest municipalities in the United States.

    Despite their success, Ezell has clients who are riddled with anxiety over what they haven’t accomplished. “My clients make a lot of money,” said Ezell. “They are still not happy and want to know why.”

    Guys are often anxious about getting ahead of peers, he said. If a friend winters in Aspen, his client wants to winter in the Alps. There is a particular pressure in status attainment—and status advancement—that fuels anxiety disorders for many.

    “We are very grateful by getting things,” Ezell said, “but we get acclimated to that status very quickly. If I am eating well; I want to be eating better.”

  • Metagenomics-based novel Caulimoviridae virus discovery and its development of identification markers in Lilium lancifolium thunb | Virology Journal

    Metagenomics-based novel Caulimoviridae virus discovery and its development of identification markers in Lilium lancifolium thunb | Virology Journal

    DNA viruses in the detected samples

    By assembling and analyzing the metagenomic sequencing data, this study only discovered two virus contig sequences, tig000081 and tig000315, which possessed the characteristics of Caulimoviridae viruses. Therefore, the two novel Caulimoviridae viruses, tig000081 (7,546 nt) and tig000315 (7,585 nt) are tentatively named “Lancifolium Caulimovirus A” (LCaA) and “Lancifolium Caulimovirus B” (LCaB), respectively.

    To validate the accuracy of the two reference contig sequences, overlapping fragments from LCaA and LCaB were cloned, sequenced, and assembled to obtain full-length genomic sequences. Final genome lengths were determined as 7,542 nt for LCaA and 7,582 nt for LCaB, with complete sequences deposited in the China National GeneBank Database (CNGB) under accession number sub064865. The open reading frame (ORF) prediction using ORF Finder (https://www.ncbi.nlm.nih.gov/orffinder/) and conserved domain analysis via InterPro (https://www.ebi.ac.uk/interpro/) revealed distinct genomic architectures of the two viruses. For LCaA, it had four ORFs: ORF1 was 963 nt and encoded a viral movement protein (MP) (aa 23–277), which was necessary for initial cell-to-cell movement during the early stages of viral infection and predicted to be responsible for the intercellular transport of viral genomes in plant cells [29]. ORF2 was 2,571 nt and encoded an 856-amino acid protein containing one Caulimovir coat domain (amino acids 427–522), homologous to coat proteins in Cauliflower mosaic virus. ORF3 was 1,656 nt and encoded a viral replication and maturation polyprotein (amino acids 104–527). This polyprotein contained one RT POL domain (139–318) and one RNase HI RT Ty3 domain (412–535). The retroviral reverse transcriptase (prototypical RT) had three enzymatic activities: RNA-dependent DNA polymerase, ribonuclease H, and DNA-dependent DNA polymerase. These activities involve copying the plus-strand RNA genome to produce minus-strand DNA, removing the RNA template, and synthesizing plus-strand DNA using minus-strand DNA as a template [30]. ORF4 was 1,233 nt and encoded a hypothetical protein (amino acids 64–393) with an uncharacterized function. (Fig. 1A). Former research had reported that the CaMV genome always encodes six proteins, a cell-to-cell movement protein, two aphid transmission factors: a polyprotein precursor of proteinase, a precursor of the capsid proteins, the reverse transcriptase and ribonuclease H, and an inclusion body protein/translation transactivator [5, 31]. Our newly detected LCa virus processed most of the key proteins of the CaMV, and ORF2 containing one Caulimovir coat domain. Based on the description of the above-mentioned LCa virus characteristics, we believe that this virus belongs to the Cauliflower Mosaic Virus.

    Fig. 1

    LCaB contained three ORFs. ORF1 encoded a viral movement protein (amino acids 47–145), which, like LCaA, was predicted to be a Caulimoviridae movement protein. ORF2 encoded a protein containing one caulimovir coat domain (amino acids 371–467), one retropepsin-like domain (amino acids 750–841), and one RT POL domain (amino acids 982–1,161). ORF3 encoded a protein with a cytoplasmic domain (amino acids 1–30), a transmembrane region (amino acids 31–50), a noncytoplasmic domain (amino acids 54–94), and another transmembrane region (amino acids 95–113) (Fig. 1B).

    The genetic evolutionary relationship of the genus Caulimovirus

    According to the International Committee on Taxonomy of Viruses (ICTV; https://ictv.global/), the genus Caulimovirus currently comprises 18 recognized species, including Cauliflower mosaic virus (CaMV) and eight other taxonomically validated members (Fig. 2). All the known genus Caulimovirus virus sequences were alignment with Mega 11 [32], and using maximum likelihood statistical method with 100 bootstrap replications to test the phylogeny. Then, the obtained tree file was up-loaded to the iTOL(https://itol.embl.de/) to beautify the graphics. Systematic phylogenetic analysis classified all reported Caulimovirus species into four well-supported monophyletic groups (Fig. 2). These species share a common evolutionary origin but subsequently diverged into four distinct lineages during key evolutionary transitions. Besides, the obtained phylogenetic tree showed that LCaA and LCaB share the closest evolutionary affinity, forming a distinct clade with Plant associated caulimovirus (PAC), Strawberry vein banding virus (SVBV), Pelargonium vein alating virus (PVA), and Malva yellow mosaic virus (MYMAV) (Fig. 2). That means within this branch, the genetic variation shared among species (the similarity of homologous gene sequences) is significantly higher than that between them and the species in other branches on the evolutionary tree. This indicates that they separated from each other for a shorter period during the evolutionary process and accumulated fewer genetic differences.

    Marker-based identification of LCa DNA viruses

    The tiger lily plants suspected to be infected with the virus were selected, and their phynotypes were shown in Fig. 3A and B. Based on Sanger sequencing and assembly of virus fragments in the pooled samples, we observed natural genetic variations in the LCaA and LCaB viruses. We finally obtained seven LCaA virus isolates and six LCaB isolates, and their genome sequences were deposited in the China National GeneBank (CNGB; accession number sub064865) and National Center for Biotechnology Information (NCBI), which is also shown in Sub Table 2. The genome sequence similarities among LCaA virus isolates ranged from 99.59 to 99.73%, while those among LCaB isolates ranged from 98.51 to 98.91%. To identify these newly discovered LCa viruses, their genome sequences were aligned using Clustal Omega (https://www.ebi.ac.uk/Tools/msa/clustalo/). Based on conserved sequences shared by LCaA and LCaB, four marker primers (listed in Table 1) were specifically designed to detect LCa viruses. Following PCR amplification, Marker 1 produced amplicons of 519 bp (LCaA) and 513 bp (LCaB), whereas Marker 2 yielded 269 bp amplicons for both variants (Fig. 3D). Furthermore, using LCaA-specific conserved sequences, Marker 3 produced a 342 bp amplicon for LCaA. Combined detection using Markers 1, 2, and 3 enabled specific identification of LCaA viruses (Fig. 3D). Marker 4 generated a 203 bp amplicon using this approach. Using Markers 1, 2, and 4, LCaB viruses were reliably identified (Fig. 3D). Furthermore, the bulbs’ DNA of the marked samples in Shuanghe town were amplified using the four primer pairs. The results showed that the Shuanghe-1(SH-1) was infected with both LCaA and LCaB, the Shuanghe-2(SH-2) was infected with LCaA, the Shuanghe-3 (SH-3) was infected with LCaB, the Shuanghe-4(SH-4) not infected with LCa virus (Fig. 3E). The above experiments demonstrated that the four primer pairs enable efficient and specific identification of LCa viruses.

M: DL2000 marker; 1 and 2: PCR products amplified via marker 1 primers (LCa-SP-F2/LCa-SP-R2) from tiger lily’s total DNA infected with and not infected with LCa viruses respectively; 3 and 4: PCR products amplified via marker 2 primers (LCa-SP-F4/LCa-SP-R4) from tiger lily’s total DNA infected with and not infected with LCa viruses, respectively; 5 and 6: PCR products amplified via marker 3 primers (LCaA-SP-F/LCaA-SP-R) from tiger lily’s total DNA infected with and not infected with LCaA virus, respectively; 7 and 8: PCR products amplified via marker 4 primers (LCaB-SP-F/LCaB-SP-R) from tiger lily’s total DNA infected with and not infected with LCaB virus, respectively; 9, 11, and 14: PCR products amplified via marker 1 primers from tiger lily’s total DNA infected with LCa viruses; 10, 12, and 15: PCR products amplified via marker 2 primers from tiger lily’s total DNA infected with LCa viruses; 13: PCR products amplified via marker 3 primers from tiger lily’s total DNA infected with LCaA virus; 16: PCR products amplified via marker 4 primers from tiger lily’s total DNA infected with LCaB virus. (E) LCa virus identification in the tiger lily bulbs from Shuanghe (SH) town. M: DL2000 marker; 1, 5, 10, and 13: PCR products amplified via marker one primers; 2, 6, 11, and 14: PCR products amplified via marker two primers; 3, 7, 12, and 15: PCR products amplified via marker three primers; 4, 8, 13, and 16: PCR products amplified via marker four primers

    At the same time, another forty tiger lily plants were randomly collected at each sample collecting point. Their DNA was extracted using the methods mentioned before. Furthermore, the extracted DNA was used as templates for PCR. Marker 1 and Marker 2 were used as the primers to detect the LCa virus in those randomly collected samples. The following identification experiments were performed as mentioned before. The results showed that the LCa virus incidence of the tiger lily in Shuanghe, Sancha, Caoba Xia, Zhengdian, and Dongshan was 10%, 1%, 2%, 2%, and 2%, respectively (Sub Fig. 1).

    Viral abundance analysis of all detected viruses

    We analyzed the DNA and RNA virus abundance based on the viral metagenomic and metatranscriptomic analysis. Only one Caulimoviridae family virus was detected using viral metagenomic sequencing data, and the above experiments demonstrated that this family Caulimoviridae virus is a newly found LCa virus. The viral abundance analysis using viral metatranscriptomic sequencing data, and the virus contigs information were provided in Sub Table 2. The viral abundance statistic data are shown in Sub Table 3. The result showed that order Sobelivirales account for 8%, Iris potyvirus A species account for 5%, Shallot yellow stripe virus species account for 4%, genus Potexvirus account for 8%, Lily symptomless virus species account for 7%, Cucumber mosaic virus species account for 3%, order Reovirales account for 0.1%, Lenarviricota phylum account for 0.005%, family Caulimoviridae account for 0.001%. Other viruses were unclassified, and nearly 64% unclassified viruses belong to the order Martellivirales. 2% of unclassified virus belong to the genus Carlavirus, and 2% belong to the order Tymovirales (Fig. 4).

  • Virtual forest bathing can reduce stress and improve mood

    Virtual forest bathing can reduce stress and improve mood

    People often feel stressed. Many don’t have time to go outside and relax. Cities keep growing, and virtual access to natural spaces feels more common while real ones feel far away.

    In Japan, people use forest bathing to reduce stress. They call it Shinrin Yoku. It simply means spending quiet time in a forest. No phones, no distractions – just nature.


    Researchers wanted to test something different. Can forest bathing work through a screen? Can people feel calmer by using virtual reality instead of going outside? They set up a study to find out.

    Building a virtual forest

    The researchers wanted to create a very realistic virtual forest experience. To do this, they filmed a 360° VR video in Sonnenberg nature reserve. This forest is the largest Douglas fir forest in Europe.

    The team didn’t stop at just recording the scenery. They also captured all the natural sounds, like the wind blowing through the trees and birds singing.

    On top of that, the researchers added the scent of Douglas fir essential oils to match what someone would actually smell in the forest. Participants in the study had different experiences based on the setup.

    Some people got the full experience. They saw the forest video through VR headsets. At the same time, they heard the forest sounds and smelled the fir scent. This gave them a complete, rich, multisensory experience.

    Other participants only experienced one sense at a time. Some only watched the forest video without sound or scent. Others only listened to the forest sounds, while some only smelled the scent without visuals or audio.

    When the researchers tested hearing or scent alone, they kept the visuals simple and plain. They wanted to avoid flashy images or colors that could distract people. The goal was to focus only on one sense at a time for clear results.

    Virtual forest improved mood

    The researchers didn’t just let people jump into the virtual forest. First, they showed participants stressful images to raise their stress levels.

    Once people felt stressed, they put on VR headsets. They then experienced one of four versions of the forest. Some got the full version. Others experienced just one sense.

    People who used sight, sound, and scent together felt the biggest mood boost. They also felt more connected to nature.

    The single-sense versions helped too but not as much. Some participants even showed slight improvements in working memory. This type of memory helps with short-term thinking and tasks.

    Still, the researchers said more studies are needed. They explained that the results may not apply to everyone.

    Study lead author Leonie Ascone is a researcher in the Neuronal Plasticity working group at the University Medical Center Hamburg-Eppendorf (UKE).

    “We can already say that digital nature experiences can absolutely produce an emotional effect – even if they don’t replace actual nature,” noted Ascone.

    VR nature in busy everyday places

    Virtual nature won’t replace real forests, but it may help in other spaces. Simone Kühn, who led the research, is director of the Center for Environmental Neuroscience at the Max Planck Institute for Human Development

    Kühn believes VR nature could help people in stressful environments. “Especially in places with limited access to nature – such as clinics, waiting areas or urban interiors – multisensory VR applications or targeted nature staging could support mental well-being.”

    “The images, sounds and scents of nature offer previously underestimated potential for improving mood and mental performance in everyday situations.”

    The research suggests that nature videos can even reduce pain in some cases. Now, Kühn sees more possibilities. Virtual nature could help people in hospitals, offices, and city spaces. It might make everyday life feel less tense.

    Nature still works, even virtually

    This study gives one simple message – nature affects people in a positive way. Even when nature appears on a screen, it still changes how people feel. The researchers saw clear improvements in mood and connection to nature, even though participants never left the room.

    But it’s important to be realistic. Virtual forest bathing is not a perfect solution. It cannot fully replace being outdoors. Real forests offer more than just sights, sounds, and smells. There is fresh air, physical movement, and other factors that VR cannot copy.

    Still, virtual forest bathing can help people who cannot easily go outside. People in hospitals, city apartments, or busy workplaces often have no access to real forests. For them, even a short virtual nature experience may reduce stress and lift their mood.

    The study is published in the Journal of Environmental Psychology.

  • Charles Leclerc leads Oscar Piastri and Max Verstappen during final Silverstone practice

    Charles Leclerc leads Oscar Piastri and Max Verstappen during final Silverstone practice

    Ferrari driver Charles Leclerc topped the timesheets during Saturday’s final practice session for the British Grand Prix, leading the way from McLaren rival Oscar Piastri and Red Bull’s Max Verstappen – as rookies Gabriel Bortoleto and Ollie Bearman endured late crashes.

    After a bright and warm first day at Silverstone, topped by home favourite Lando Norris, cloudy, cooler conditions greeted the drivers for FP3, which gave them one more chance to tweak their cars ahead of the mid-afternoon Qualifying hour.

    When the session got under way at a slightly delayed time of 1135, drivers gradually trickled out on track to begin their programmes and assess the conditions – Pirelli’s soft, medium and hard compound tyres all being used in the opening minutes.

    Lewis Hamilton was one of the early movers when the action got under way, bolting on a set of soft tyres and clocking a 1m 26.529s to hold the provisional P1 spot, which prompted plenty of cheers from the packed grandstand and grass banks around the track.

    As per Friday’s running, there were some significant gusts of wind for Hamilton and the rest of the drivers to deal with – seemingly highlighted when Lance Stroll drifted his way out of the Luffield hairpin and just about prevented his Aston Martin from spinning.

    Kimi Antonelli also reported a “massive moment” through the Maggotts and Becketts complex when he began to push, while there was drama for Alex Albon when he faced a slow-moving Aston Martin at the entry to Copse and swore over the radio to express his frustration.

    As for lap times, Leclerc used the soft tyres to get down to a 1m 25.922s and take over from team mate Hamilton in P1, a couple of tenths clear of a more competitive looking Max Verstappen, who nonetheless complained of brake bias difficulties.

    “A little bit of rain,” Leclerc then commented over the radio with around 20 minutes to go, but it was nowhere near enough to stop drivers from pumping in laps on slicks and making improvements – George Russell proving this when he slotted into second position.

    With some 15 minutes remaining, Norris sent the home crowd wild again by going quickest on a 1m 25.606s, followed closely by Verstappen and team mate Piastri via similarly significant gains, before Leclerc fired in a 1m 25.498s to reclaim P1.

    Hamilton was also on a rapid lap at this point, hitting the Sector 2 beam 0.074s clear of Leclerc, only for the red flag to be thrown for debris on track – meaning he had to abandon the effort. “We think the bodywork might be yours,” was the subsequent message to Haas driver Bearman.

    The session resumed with a few minutes to go but was soon halted again when Gabriel Bortoleto lost control of his Kick Sauber through the aforementioned Maggotts/Becketts sweeps, bounced over the grass and ended in the gravel with suspension damage.

    It meant Leclerc ended up fastest over Piastri, Verstappen and Norris, with Yuki Tsunoda an encouraging fifth for Red Bull, Bearman taking sixth despite another moment late on when he misjudged his entry to the pit lane and damaged his front wing, and Albon putting Williams back into the top 10 positions.

    Russell was the fastest of the Mercedes cars on a so far difficult weekend for the Silver Arrows, placing eighth over the Racing Bulls of Isack Hadjar and Liam Lawson, Hamilton, and the other Williams and Haas machines of Carlos Sainz and Esteban Ocon.

    Next up was Antonelli in 14th, as the Saubers of Nico Hulkenberg and Bortoleto along with the Aston Martins and Alpines brought up the rear – Fernando Alonso placing in front of Franco Colapinto, Stroll and Pierre Gasly.
