    Covid-19 seems to age blood vessels – but only among women | The Transmission

    New Scientist Women’s arteries seem to be stiffer if they have had covid-19, with the same effect not being found among men.Covid-19 seems to accelerate the ageing of blood vessels, but perhaps only among women.

    The infection has previously been linked to cardiovascular complications, like heart disease, but how it has this effect isn’t entirely clear. To learn more, Rosa Maria Bruno at the Université Paris Cité in France and her colleagues recruited 2390 people, aged 50 on average, from 16 countries – including the UK and US – between September 2020 and February 2022.

  • Firms Face Scrutiny for Misleading Baby Teeth Claims

    Firms Face Scrutiny for Misleading Baby Teeth Claims

    Parents are spending thousands of pounds to bank stem cells from their children’s milk teeth – but the recipient companies’ claims about their future medical value are unproven and potentially misleading, reveals an investigation by The BMJ, published today.

    The companies’ claims include that stem cells banked from teeth are already being used in treatments for autism and diabetes. They also highlight current research using stem cells in multiple sclerosis, Parkinson’s disease, and heart attacks.

    Tooth stem cell banking involves parents sending their children’s lost milk teeth to a laboratory where the dental pulp stem cells are harvested and stored. The service costs around £1900 (€2189; $2573) with an additional annual storage fee of £95, explains freelance journalist Emma Wilkinson.

    The three companies in the UK offering tooth stem cell banking – Future Health Biobank, BioEden and Stem Protect – all operate through one laboratory.

    Future Health Biobank says on its website that it has released 26 tooth stem cell samples for treatment, including for autism, type 1 diabetes, and knee cartilage regeneration, all to private clinics in North America.

    BioEden states it has “already witnessed the remarkable evidence of these ongoing developments” among its own customers, while Stem Protect cites cleft palate repair, sickle cell disease, HIV/AIDS, severe combined immunodeficiency, and knee cartilage repair under a section of its website headed, ‘What treatments are tooth stem cells used for?’

    But several experts are concerned about the claims being made, which they say risk exploiting parents, with the autism treatment promise deemed particularly “outrageous.”

    Jill Shepherd, senior lecturer in stem cell biology at the University of Kent, says companies are selling the “potential” for something that is not yet borne out by the science. “There is a lack of evidence and a paucity of research using dental pulp stem cells to treat patients.”

    Sufyan Hussain, an investigator on the UK arm of a global clinical trial evaluating stem cell therapy for type 1 diabetes, also has concerns about what is being promised. “At present, there isn’t a definitive answer regarding the optimal source of stem cells for future diabetes therapies,” he says.

    Tim Nicholls, assistant director of policy, research and strategy at the National Autistic Society in the UK, adds: “It’s outrageous that tooth stem cell procedures are being advertised to parents with the false claim of ‘treating’ autism.

    “Autism is not a disease or illness, it cannot be treated and there is no cure. It is dangerous and morally bankrupt to target potentially vulnerable people with expensive procedures that could, in fact, cause harm.”

    Experts are also concerned about the lack of independent information on tooth stem cell banking to help consumers make a fully informed choice, and say more oversight is needed of the information being used to promote the practice.

    Jill Shepherd also believes parents should be given more information on what type of tests are done to validate that stem cells are present in the stored samples, that the samples have been collected properly, and the evidence on how long such samples can be viably stored.

    The BMJ has raised several concerns about how the service is promoted on all three company websites with the Advertising Standards Agency, which it says it will review.

    In response, Future Health Biobank says it is reviewing how information on its site is presented to ensure “readers can clearly distinguish between client experiences and formally published clinical outcomes.”

    The company also says it has a “robust, ongoing, storage stability validation programme” with quality control testing “to ensure that there is no deterioration in the integrity, viability or future potential of biological samples.”

    Stock Market Today: Dow, S&P Live Updates for August 21

    Asian technology stocks perked up in early trade after dip buyers helped lift US stocks from their lowest levels of the day.

    South Korea’s Kospi index rose over 1%, led by a gain in Samsung Electronics Co. shares. LG Display Co. climbed in Seoul while Advantest Corp. jumped 4% in Tokyo. The S&P 500 fell 0.2% and the Nasdaq 100 retreated 0.6%, still above the lowest levels of the day. Oil held its gains after a report showed a drawdown in US reserves. Treasuries steadied Thursday after climbing across the curve in the prior session.

    Tech Stocks Rise in Asia, Nasdaq Futures Rebound: Markets Wrap

    (Bloomberg) — Asian technology stocks gained while Nasdaq 100 futures rebounded from earlier declines, after dip buyers stepped in to steady the index late in US trading.

    Two stocks rose for every one that declined in the MSCI Asia Pacific Technology Index. Advantest Corp. and Samsung Electronics Co. were among the gainers. Taiwan Semiconductor Manufacturing Co. rose 0.9% after its biggest one-day fall in four months Wednesday. Contracts for the Nasdaq 100 index advanced 0.1%.

    Oil held its gains after a report showed a drawdown in US reserves. Treasuries steadied after climbing across the curve in the prior session. The yield on Japan’s 20-year government bond rose to the highest since 1999 while China’s 30-year government bond yield reached the highest since December as a selloff accelerated amid a rally in local stocks.

    Technology shares – particularly megacap companies – were under pressure over the past two sessions, as a steep rally since April stoked concern it may have gone too far, too quickly. Still, markets are in a wait-and-see mode as central bankers convene in Jackson Hole, Wyoming, with investors awaiting remarks from Federal Reserve Chairman Jerome Powell.

    “There remains a bearish skew for equities at the moment,” said Kyle Rodda, a senior market analyst at Capital.com in Melbourne. “Equity prices are beginning to reflect the risk of disappointment at Jackson Hole, with doubts circulating about whether the Fed will pivot as aggressively in the dovish direction implied by rates markets – or even pivot at all.”

    Technology stocks dropped Wednesday with the Nasdaq 100 index declining for a second consecutive day. A gauge of the so-called ‘Magnificent Seven’ tech firms fell for a fourth consecutive day, the longest losing streak since mid April.

    US stocks are “in the early days” of a bubble, although the critical point for a correction has yet to come, Oaktree Capital Management LP co-founder Howard Marks cautioned.

    Declines for US megacaps dragged down the S&P 500 for a fourth straight session, despite a bounce off session lows. While most major groups in the US equity benchmark finished higher, some strategists warned that the extra-heavy weighting of tech giants may turn the “rotation” out of the sector into a broader rout.

    “Rotation can only take place if the tech stocks hold up,” said Matt Maley at Miller Tabak. “If they decline, the only rotation we’ll see will be into cash.”

    Meanwhile, minutes of the Federal Open Market Committee’s July 29-30 meeting showed most Fed officials highlighted inflation risks as outweighing concerns over the labor market at their meeting last month, as tariffs fueled a growing divide within the central bank’s rate-setting committee.

    Officials acknowledged worries over higher inflation and weaker employment, but a majority of the 18 policymakers in attendance “judged the upside risk to inflation as the greater of these two risks,” according to the minutes.

    Given the Fed is already split on rate cuts, “the balance is going to shift in favor of those doves, who are going to be more willing to look through tariff-driven inflation,” Ian Samson, a multi-asset portfolio manager at Fidelity International, said in a Bloomberg TV interview.

    In other Fed news, Governor Lisa Cook signaled her intention to remain at the central bank in defiance of calls for her resignation by President Donald Trump over allegations of mortgage fraud.

  • These Foods May Lower GI Cancer Risk by 36%

    These Foods May Lower GI Cancer Risk by 36%

    • A new study suggests white-fleshed produce may reduce GI cancer risk by 36%.
    • Red and purple vegetables may lower risk by up to 32%.
    • Gastrointestinal cancers are on the rise globally and in the U.S.

    Gastrointestinal cancers include any cancer of the GI tract—stomach, liver, esophageal, pancreatic and colorectal. They represent more than 25% of all cancers, with 5 million new cases of gastrointestinal cancers and 3 million associated deaths in 2018. What’s more, the rate of gastrointestinal cancers in people under 50 is rising at an alarming rate, according to a July 2025 report.

    As with many other diseases, lifestyle plays a large role in cancer risk. The American Cancer Society focuses especially on diet, physical activity, smoking and alcohol intake as areas that have the most influence over cancer risk.

    While there is a lot of evidence regarding the role fruits and vegetables can play in reducing cancer risk, researchers from Korea wanted to see if certain colors of produce made a bigger difference than others. They published their findings in Nutrition Research. Let’s break them down.

    How Was This Study Conducted?

    Researchers enrolled more than 11,000 participants who were attending health check-ups at the National Cancer Center (NCC) in Korea between October 2007 and December 2021. Participants were followed for an average of eight years, during which time 214 gastrointestinal cancers were diagnosed; researchers gathered diagnosis data from the Korea Central Cancer Registry and NCC electronic medical records.

    Researchers collected data via two baseline questionnaires. One gathered demographic information, including age, sex, smoking status, alcohol consumption, educational level, household income, occupation, marital status, physical activity and family history of cancer. The other one was a food frequency questionnaire that asked about consumption of 106 culturally-relavant foods, including frequency and amounts.

    Researchers also classified fruits and vegetables according to their colors. But instead of going by the exterior color, they went by the color of the flesh. So where some might consider apples as falling into red fruits, pears into green or yellow and bananas as yellow, those examples were categorized as being white for this study, since their flesh is white. This is partly because people in Korea tend to remove the peel of fruits like apples and pears, so researchers felt this was more applicable to real life. 

    What Did This Study Find?

    After running statistical analyses, including adjusting for demographics, researchers found the following major findings:

    Researchers also point out several limitations to this study. First, because it was specifically done with a Korean population, it is unknown if these results extend to other populations. Also, a follow-up of eight years is relatively short for cancer development, so a longer follow-up may offer more accurate results. Lastly, all gastrointestinal cancers were lumped together, so researchers can’t say if certain colors are more effective for certain types of gastrointestinal cancers. 

    How Does This Apply to Real Life?

    While we can’t perfectly convert the 188 g/day of white fruits and veggies into cups, we can get close by offering examples. For instance, 188 grams would be about 1 ¾ cups chopped cauliflower, a large golden delicious apple or two small bananas. As for the red and purple fruits and veggies, 34 grams would be about two medium slices of tomato or a couple of large strawberries. These amounts can all contribute to the USDAs recommendation of 2 cups of fruit and 3 cups of vegetables per day.

    Eating enough fruits and vegetables has been shown to have many health benefits, including a reduced risk of heart disease, stroke and cancer, as well as improved brain health and longevity. And while you can certainly eat fruits and veggies “as is,” there are also many delicious ways to prepare them. And light cooking processes may even increase the bioavailability of certain nutrients, like lycopene, beta-carotene and calcium, as can eating produce with a little bit of fat.

    It’s easy to toss veggies into egg dishes or create dips to scoop up with veggies. Some of our other favorite ways to prepare veggies include:

    Of course, vegetables don’t have to have all the fun. While fruit is easy to grab and go, it’s also amazing in baked oatmeal, in a smoothie bowl or in a breakfast parfait. You can also add sliced fruit on top of toast or turn it into fresh fruit butter or chia seed jam. Did someone say dessert? You’ll love our Lemon-Blueberry Tiramisu, Easiest Apple Tarts and our simple Baked Peaches.  

    Our Expert Take

    This study suggests that eating more fruits and vegetables may reduce your risk of gastrointestinal cancers. They found that white-fleshed produce seemed to have the most impact, followed by red and purple produce. Researchers credit the antioxidants in produce for most of their protective effects. Find fun, tasty new ways to incorporate produce into your day, shooting for at least 2 cups of fruit and 3 cups of vegetables each day.

  • A New Model for Early Black Hole Formation Could Revolutionize Cosmologicy

    A New Model for Early Black Hole Formation Could Revolutionize Cosmologicy

    When the James Webb Space Telescope (JWST) commenced operations, it provided the first views of the period known as Cosmic Dawn. This cosmological epoch, which took place between 50 million and one billion years after the Big Bang, was when the first stars and galaxies in the Universe formed. What Webb’s observations revealed of this period surprised and intrigued scientists. In addition to spotting numerous “Little Red Dots” (LRDs), particularly bright and red galaxies, it also observed the “seeds” of Supermassive Black Holes (SMBHs).

    These findings were in tension with current models of cosmology, as the BRDs and black holes appeared too large to have formed less than 1 billion years after the Big Bang. This prompted scientists to develop new and interesting theories regarding stellar and black hole formation during the Cosmic Dawn period. In a new theoretical study, University of Virginia astrophysicist Jonathan Tan proposes a comprehensive framework for the birth of SMBHs that suggests that they formed as the remnants of the earliest stars in the Universe.

    Tan is a research professor with the College and Graduate School of Arts & Sciences’ Department of Astronomy and a professor in the Department of Space, Earth and Environment at Chalmers University of Technology in Gothenburg, Sweden. The paper that describes his “Pop III.1” theory was recently published in Astrophysical Journal Letters. In addition to offering an explanation for the formation of SMBH seeds, his proposed theory could revolutionize our understanding of the cosmological period known as the “Epoch of Reionization.”

    According to the most widely accepted theory of cosmology, known as the Lambda Cold Dark Matter (LCDM) model, the Universe was enshrouded in darkness shortly after the Big Bang. This period is known as the “Cosmic Dark Ages,” where the Universe was permeated by neutral hydrogen. The only sources of light were photons from the “relic radiation” left over by the Big Bang – the Cosmic Microwave Background (CMB) – and those released by the reionization of neutral hydrogen. This latter source of photons was created by all the ultraviolet radiation released by the first stars in the Universe, Population III, which were particularly massive, bright, and short-lived.

    Hence why astronomers also refer to this cosmological epoch, which took place from roughly 380,000 to 1 billion years after the Big Bang, as the “Epoch of Reionization.” In addition, scientists have known for decades that Supermassive Black Holes reside at the center of massive galaxies and play a vital role in their evolution. For a long time, it was theorized that SMBHs existed during the early Universe and were part of the first galaxies, which was confirmed by Webb’s observations. However, the black hole seeds were larger than the predominant cosmological model allowed for. This discovery injected new life into the debate surrounding how these gravitational behemoths formed.

    On the one side, some scientists argued that SMBHs formed from smaller black holes, or the stellar remnants of Population III stars that underwent gravitational collapse at the end of their lives. On the other side, some astronomers theorized that SMBHs formed from giant clouds of dust that collapsed without first becoming stars – aka. Direct Collapse Black Holes (DCBHs). Tan’s proposed Pop. III.1 model endorses the direct collapse school of thought. As he explained in a University of Virginia press release, this theory could have implications for several aspects of cosmology:

    Our model requires that the supermassive star progenitors of the black holes rapidly ionized the hydrogen gas in the Universe, announcing their birth with bright flashes that filled all of space. Intriguingly, this extra phase of ionization, occurring much earlier than that powered by normal galaxies, may help resolve some recent conundrums and tensions that have arisen in cosmology, including the “Hubble Tension”, “Dynamic Dark Energy,” and preference for “Negative Neutrino Masses,” all of which challenge the standard model of the Universe. It’s a connection we didn’t anticipate when developing the Pop III.1 model, but it may prove profoundly important.

    Evidence supporting the existence of DCBHs has existed for some time, as indicated by strange quasars that existed as early as 500 million years after the Big Bang. But thanks to Webb, astronomers are seeing the first direct evidence of these early black holes. Said Richard Ellis, one of the world’s leading observational cosmologists and a professor of astrophysics at University College London:

    Professor Tan has developed an elegant model that could explain a two-stage process of stellar birth and ionization in the early Universe. It’s possible the very first stars formed in a brief, brilliant flash, then vanished — meaning what we now see with the James Webb Telescope may be just the second wave. The Universe, it seems, still holds surprises.

  • South African spinner Prenelan Subrayen reported over suspect action during win over Australia

    South African spinner Prenelan Subrayen reported over suspect action during win over Australia

    South Africa’s spinning all-rounder Prenelan Subrayen has been reported for a suspect bowling action after the Proteas’ victory in the first one-day international against Australia.

    The 31-year-old off spinner, who took the key wicket of Travis Head early on before taking 1-46 in his 10 overs, had been making his ODI debut in the 98-run win in Cairns on Tuesday.

    But in the match officials’ report, concerns were cited about the legality of his bowling action.

    With Subrayen now having to face an independent assessment of his action at an ICC-accredited testing facility within 14 days, the news is a blow to the Proteas, who are already having to cope without injured star paceman Kagiso Rabada.

    After losing the T20I series 2-1, the Proteas are eyeing revenge in the ODI series with two matches still to be played in Mackay on Friday and Sunday.

    It was only two months ago that Subrayen also earned his first Test appearance against Zimbabwe in Bulawayo, and he was immensely proud and emotional after the honour of receiving his first ODI cap in Cairns.

    Subrayen has previously had plenty of scrutiny over his action, starting well over a decade ago.

    In December 2012, Cricket South Africa (CSA) placed him under rehabilitation after two separate independent tests showed his action to be illegal, but he was cleared to bowl again in January 2013 after re-testing.

    Subrayen was subsequently reported twice during the following two years during matches, before he was eventually cleared to resume bowling after having his action examined at South Africa’s national performance centre in March 2016.
