    Key Takeaways


    • Many different alternative ideas about our cosmic origins abounded until the mid-1960s, when the discovery of the CMB, identified as the Big Bang’s leftover glow, was first identified.

    • In all that time since, observations have confirmed and strengthened this picture, while subsequent CMB analysis has revealed even more information about our primeval Universe.

    • Many think that the story of the CMB ended with Planck, but the past 10 years have shown that so much more remains to be discovered. Come join us on the frontiers in this fascinating CMB-focused podcast episode!

    Perhaps the strongest evidence we’ve ever acquired in support of the Big Bang has been the discovery of the leftover radiation from its early, hot, dense state: today’s cosmic microwave background, or CMB. While there were many competing ideas for our cosmic origins, only the Big Bang predicted a uniform, omnidirectional bath of blackbody radiation: exactly what the CMB is.

    But it turns out the CMB encodes much more information than just our cosmic origins; it allows us to map the very early Universe from when it was just 380,000 years old, and gives us vital information about what has happened to light from that time over its 13.8 billion year journey to our eyes. It encodes information about our cosmic expansion history, about dark matter and dark energy, about intervening galaxy clusters, and about the material here in our own galaxy, along with much more. It is, arguably, the richest source of information from any one single observable in our entire Universe.

    Here to guide us through what CMB scientists are working on here in 2025, including what we’ve learned and what we’re still trying to find out, I’m so pleased to welcome Dr. Patricio Gallardo to the show. We’ve got more than an hour and a half of quality science to go through, and by the end, I bet you’ll be more excited about the upcoming Simons Observatory, designed to measure the CMB to higher precision than ever before, than you knew you should be. Enjoy!

    The CMB has long been considered the Big Bang’s “smoking gun” evidence. But after what JWST saw, might it come from early galaxies instead?

    Originally, the abundance of bright, early galaxies shocked astronomers. After 3 years of JWST, we now know what’s really going on.

    For over 50 years, it’s been the scientifically accepted theory describing the origin of the Universe. It’s time we all learned its truths.

    If you want to understand the Universe, cosmologically, you just can’t do it without the Friedmann equation. With it, the cosmos is yours.

    The hunt for extraterrestrial life begins with planets like Earth. But our inhabited Earth once looked very different than Earth does today.

  • Anti-ageing or life-threatening? What experts say after Shefali Jariwala’s death

    Anti-ageing or life-threatening? What experts say after Shefali Jariwala’s death

    Experts warn of the rising popularity of these largely unstudied products, citing potential harmful side effects, especially from intravenous injections bypassing natural bodily protections

    The sudden demise of actress Shefali Jariwala has sparked fresh debate over the safety and regulation of anti-ageing medicines in India.

    The 42-year-old, who shot to fame with the 2002 music video Kaanta Laga, passed away on June 27 in Mumbai, reportedly due to cardiac arrest.

    However, emerging reports suggest she had been self-administering a combination of anti-ageing injections while fasting, raising serious concerns about the unregulated use of such treatments.

    What are anti-ageing medicines and are they regulated?

    Experts have warned that while anti-ageing treatments are becoming increasingly popular, many products in the market are not backed by proper scientific studies and remain largely unregulated.

    “Anti-ageing medicine is becoming very popular but it’s mostly unregulated. Many of these products are sold without proper scientific studies to prove they work. Some may even have harmful side effects, especially if taken for long periods,” said former AIIMS Director, Dr Randeep Guleria, in a statement.

    Is ‘anti-ageing’ even a scientific term?

    Medical professionals also stress that the term ‘anti-ageing’ itself is misleading.

    “Anti-ageing is not a scientific term. Such products do not reverse or stop natural ageing. Skin whitening is possible with certain medications, but that is not the same as anti-ageing,” said Dr Rajeev Jayadevan, Convener, Research Cell, Kerala State IMA.

    What was Shefali Jariwala using?

    Reports from the ongoing police investigation suggest that Shefali had been using skin-whitening and anti-ageing injections, particularly glutathione and Vitamin C, for around eight years. Importantly, she was not under active medical supervision during this period, aside from an initial consultation.

    Dr Jayadevan explaining the dangers of this approach said, “When a medication is given as an IV injection, it bypasses the natural protection offered by gut absorption and liver metabolism. Thus, the drug may reach very high concentrations in blood and tissues.”

    He further warned, “IV medications must be carefully regulated and contamination avoided at all costs.”

    Are these injections safe?

    According to Dr Jayadevan, there have been international incidents highlighting the risks.

    “There are reports from Australia and Philippines about contamination of IV glutathione vials with toxins and also serious side effects of such products,” he added.

    Why are these products still popular?

    India is witnessing a cosmetic boom, fuelled by rising aspirations and social media influence. According to the latest ISAPS Global Survey, India ranks among the top 10 countries globally for aesthetic and cosmetic procedures, behind only the US, Brazil, and Japan.

    However, this rapid rise is not without consequence.

    Should these medicines be banned?

    Experts believe regulation is the need of the hour and that banning harmful products should not be ruled out.

    “There is definitely a need to regulate such medicines. If there’s no proper evidence about their safety or usefulness, and they are found to be harmful, then yes — they should be banned,” said Dr Guleria. “The same applies to other medicines, like muscle-building drugs that are often misused.”

  • Doctor explains how to spot magnesium deficiency and best sources to get vital mineral safely – Life News

    Doctor explains how to spot magnesium deficiency and best sources to get vital mineral safely – Life News

    We all have been bombarded with how magnesium supplements will cure our fatigue, leg pains and more. But do we all need magnesium, and should we take magnesium over the counter without any tests? Dr Rakesh Gupta, senior consultant, internal medicine, Indraprastha Apollo Hospitals, says: “While magnesium supplements are available over-the-counter (OTC), it’s not always advisable to take them without knowing your actual need. Magnesium is an essential mineral, but unnecessary supplementation can lead to side effects such as diarrhea, abdominal cramps, and in rare cases, toxicity-especially in people with kidney problems. In many cases, a balanced diet provides sufficient magnesium. If you’re experiencing symptoms like fatigue, muscle cramps, or irregular heartbeat, it’s better to consult a healthcare professional. They may recommend a blood test to check magnesium levels or assess your symptoms and dietary intake. Self-medicating with supplements, especially in high doses, isn’t safe or effective for everyone. It’s also important to consider interactions with other medications, such as antibiotics or diuretics. In short, while magnesium is vital, supplements should not be taken casually or as a blanket solution without understanding individual needs.

    What does magnesium do in our bodies and what is the optimum source of intake?

    Magnesium plays a crucial role in over 300 biochemical reactions in the body. It supports muscle and nerve function, regulates blood pressure, helps in energy production, maintains a healthy heartbeat, and is vital for bone health. It also plays a role in mood regulation and blood sugar control. The best and safest way to meet your magnesium needs is through food. Good dietary sources include green leafy vegetables (like spinach), nuts (especially almonds and cashews), seeds, legumes, whole grains, and bananas. Dark chocolate and certain fish like mackerel also contain magnesium. The recommended dietary allowance (RDA) for adults is around 310-420 mg per day depending on age and sex. When intake is through food, the risk of excess is low, and the absorption is more balanced. Supplements may be necessary only for those with confirmed deficiency, poor diet, or absorption issues.

    What are the symptoms of magnesium deficiency and how can we check for the deficiency?

    Magnesium deficiency can be subtle at first, but over time, it may present with symptoms like muscle cramps or twitches, fatigue, numbness or tingling, mood swings, irritability, poor sleep, and irregular heartbeat. In more severe cases, deficiency can lead to low calcium or potassium levels, which can further affect nerve and muscle function. However, because only about 1% of magnesium is found in the blood, standard blood tests may not always detect low tissue levels. A better assessment includes considering symptoms, dietary intake, medical history, and sometimes specialised tests like red blood cell magnesium levels. Chronic conditions such as diabetes, gastrointestinal disorders, alcoholism, and the use of certain medications can also raise the risk of deficiency. If you suspect low magnesium, consult your doctor rather than self-diagnosing. They can recommend appropriate tests or a trial of dietary changes before jumping to supplementation.

    Who should avoid magnesium supplements?

    Certain people should be cautious of magnesium supplements unless prescribed. Those  with kidney disease are at high risk, as their kidneys may not effectively remove excess magnesium, which can lead to toxicity. Symptoms of excess magnesium include nausea, low blood pressure, irregular heartbeat, confusion, and in extreme cases, coma. People on  medications like antibiotics (especially tetracyclines and quinolones), muscle relaxants, or diuretics should also be careful, as magnesium can interact with these drugs and affect absorption or efficacy. Those with heart block or certain digestive disorders that impair magnesium absorption should not take supplements without medical guidance. Pregnant or breastfeeding women should also follow prescribed limits. Magnesium from food is generally safe for everyone, but supplementation should be tailored to individual needs and medical history. Always talk to a healthcare provider before starting any new supplement, even if it’s available OTC.

  • Envisioning The Distance Ladder In The Era Of The Habitable Worlds Observatory

    Envisioning The Distance Ladder In The Era Of The Habitable Worlds Observatory

    A comparison of state-of-the-art geometric distances that serve to anchor the distance scale and their current relative uncertainties. Additional candidate (≲1 Mpc) eclipsing binary hosts to target in future are also pictured. Current EB distances to M31 and M33 rely on early-type stars and are not precise enough to be included in H0 determination (Vilardell et al. 2010; Bonanos et al. 2006), but we expect this will improve with more sensitive moderate- to high-resolution spectroscopy capable of characterizing late-type EB systems. — astro-ph.CO

    The current state-of-the-art cosmic distance ladder requires three rungs–geometric distances, primary indicators, and Type Ia Supernovae–to achieve a 1% measurement of the Hubble constant H0.

    The Habitable Worlds Observatory will have the sensitivity and resolution to reduce this to a two-step measurement, eliminating the third rung entirely and reaching into the Hubble flow with stellar distance indicators such as Cepheid variables and the tip of the red giant branch alone.

    We discuss the requirements for a program to measure H0 to 1% with HWO here, including telescope and instrument design considerations. We also comment on the potential of HWO to measure distances to low-mass dwarf galaxies via their RR Lyrae stars.

  • Apple is reportedly working on a cheaper MacBook, but will it stick the landing?

    Apple is reportedly working on a cheaper MacBook, but will it stick the landing?

    This week, we heard some news from analyst Ming-Chi Kuo about Apple entering a new segment of the laptop market. The company is reportedly working on a new MacBook at a lower starting price point than the MacBook Air, and it’ll apparently pack the A18 Pro chip found in iPhone 16 Pro and iPhone 16 Pro Max.

    While a cheaper MacBook is certainly a welcome add, the question truly stands: will Apple do it properly, or will it serve as another decoy model?

    Rumor refresh

    To quickly recap, the cheaper MacBook is rumored to use a 13-inch display, pack an A18 Pro chip, and come in the same four colors as Apple’s entry-level iPad: blue, yellow, pink, and silver. It’ll enter mass production in the fourth quarter of this year, or first quarter of 2026.

    Ultimately, theres precedent for both sides. When Apple introduced the redesigned entry-level iPad in 2022, it started at $449, making it not incredibly affordable – at least compared to its predecessor at $329.

    Sure, Apple made a cheaper iPad that looked incredibly visually similar to the higher end iPad Air, but it wasn’t a particularly fantastic deal either. Especially once you consider the fact that iPad Airs regularly went on sale for $499 at the time, leaving just $50 in price difference to gain an M1 chip, a laminated display, and more. Two years later, that iPad now starts at just $349, and often goes on sale for $299 – which is far more competitive.

    What would Apple cut?

    People are generally speculating that this new entry-level MacBook will start between $699 and $799, which seems fair – depending on how Apple positions it.

    Last fall, Apple updated all of its MacBook Air models to start with 16GB of RAM, providing a potential hint at something it could cut from an A18 Pro powered MacBook: unified memory.

    I could see this entry-level MacBook retaining 8GB of RAM, which wouldn’t necessarily be too big of a loss on its own.

    However, Apple could also cut some niceties from the entry-level MacBook: an extra USB-C port, Touch ID, a Center Stage webcam, and battery capacity could all be cut.

    New MacBook: good value?

    Out of all of those cuts, I think Touch ID might be one of the harder ones to stomach for most people. That said, there is precedent for it. Apple’s base model M4 iMac does not come with a Touch ID keyboard.

    If the MacBook comes in at $699 with 8GB of RAM and all of these feature cuts, it likely wouldn’t be too bad of a bargain. $799 makes that a much tougher sell. Given all of the fluctuating tariffs, Apple might not want to price it too low from the start, so a $799 MacBook seems much more probable.

    At $799, if it comes with 8GB of RAM and cuts a plethora of key Mac features, it might not be the best value. After all, MacBook Airs tend to go on sale for around that price level. M4 MacBook Air (which starts with 16GB of unified memory) is currently on sale for $849, and just a couple days ago we saw clearance M3 MacBook Airs (also with 16GB of unified memory) for just $699.

    Another thing worth mentioning is that there’d definitely be a $50-$100 education discount on this MacBook, bringing that $699-799 starting price point down to $599, $649, $699, or $749 for students in the US.

    Wrap up

    Obviously, those deals aren’t 24/7 – but it provides a picture of what can already exist in the market. Ultimately, Apple’s biggest competitor to this cheaper MacBook will be online retailers providing discounts on older MacBook Air models.

    If Apple were to release a cheaper MacBook without cutting too many key features, I’d be pleasantly surprised. Ultimately, this MacBook is still 3-9 months away from release, so a lot is still up in air. Kuo predicts that Apple will sell 5-7 million units of this MacBook model in 2026, suggesting that Apple is confident in what’ll put out.

    What do you think of the cheaper MacBook rumor? Do you think Apple will strike a nice balance? Let us know in the comments.

  • Japan braces for more quakes, authorities dismiss doomsday hype

    Japan braces for more quakes, authorities dismiss doomsday hype



    CNN
     — 

    Japan’s government on Saturday warned of more possible strong earthquakes in waters southwest of its main islands, but urged the public not to believe unfounded predictions of a major disaster.

    Authorities on Friday evacuated some residents from remote islands close to the epicenter of a 5.5-magnitude quake off the tip of the southernmost main island of Kyushu.

    That quake on Thursday, strong enough to make standing difficult, was one of more than 1,000 tremors in the islands of Kagoshima prefecture in the past two weeks that have fueled rumors stemming from a comic book prediction that a major disaster would befall the country this month.

    “With our current scientific knowledge, it’s difficult to predict the exact time, place or scale of an earthquake,” said Ayataka Ebita, director of the Japan Meteorological Agency’s earthquake and tsunami monitoring division, after a 5.4-magnitude quake shook the area again on Saturday.

    “We ask that people base their understanding on scientific evidence,” Ebita told a press conference.

    The manga, which some have interpreted as predicting a catastrophic event on Saturday, has prompted some travelers to avoid Japan. Arrivals from Hong Kong, where the rumors have circulated widely, were down 11% in May from the same month last year, according to the latest data.

    Japan has had record visitor numbers this year, with April setting an record monthly high of 3.9 million travelers.

    Ryo Tatsuki, the artist behind the manga “The Future I Saw,” first published in 1999 and re-released in 2021, said she was “not a prophet,” in a statement issued by her publisher.

    Earthquakes are common in Japan, one of the world’s most seismically active areas. It accounts for about one-fifth of the world’s earthquakes of magnitude 6 or greater.

  • Challenge-Based Funding To Spark Origins Breakthroughs

    Challenge-Based Funding To Spark Origins Breakthroughs

    Earth’s surface is shown as it might have looked some 3.8 billion years ago, perhaps when life was just beginning, in this artist’s rendering. Illustration: NASA/JPL-Caltech/Lizbeth B. De La Torre

    Origins of life research is marred by ambiguous questions and goals, creating uncertainty about when research objectives have been achieved.

    Because of numerous unknowns and disagreements about definitions and theories, the field lacks clear markers of progress. We argue that the origins community should focus on goals that have agreed-upon meaning and can be consensually categorized as achieved or unachieved.

    The origins community needs these goals to maintain coherence amongst a federation of problems with the shared, but nebulous aspiration of understanding the origins of life. We propose a list of challenges with clear ‘Finish Lines’–explicit descriptions of what will be achieved if each goal is reached–similar to the X-prize model.

    The intent is not to impose top-down research directions, but to compel the community to coalesce around explicit problems of the highest priority, as physics, astronomy, and planetary science communities do when setting science objectives for missions and megaprojects.

    Even if the generated phenomena are not unequivocally life-like, demonstrating systems that achieve these goals will sharpen the distinction between life itself and the constellation of phenomena that co-occur with life.

  • Simulation of Images of Protoplanetary Disks After Collision with Free-floating Planets

    Simulation of Images of Protoplanetary Disks After Collision with Free-floating Planets

    The color shows the product of the radiation flux at a wavelength of 3 µm and the square of the distance for the case of a prograde fall of the planet onto the disk. Model parameters: q = 5 AU, ω = 90◦ , i = 10◦ . The time moment t = 200 years from the beginning of the calculations is shown on the left, t = 290 years is shown in the center, and t = 500 years is shown on the right. The upper graphs correspond to the direction of the line of sight against the z axis, and the lower ones along the y axis. — astro-ph.EP

    Observational manifestations of disturbances in a protoplanetary disk caused by a collision with a massive planet are studied.

    It is assumed that the planet moves along a parabolic trajectory that intersects the disk plane near the star. Gas-dynamic simulation is performed using the finite volume method on a long time scale. On its basis, images of the disk observed from the pole and edge-on are constructed in the infrared and submillimeter ranges.

    A wide range of planet orbit parameters is considered. The approach of the planet was considered both prograde and retrograde with the respect to the disk rotation. Calculations have shown that in the images of the disk seen pole-on, two spiral arms can be observed in case of the prograde fall, and one with retrograde case.

    In the case of observations of a disk whose plane is inclined at a small angle to the line of sight, distortions of the disk plane can be noticeable. In addition, a gas tail is extended from the disk in the direction of the planet’s motion, which can also be identified in observations.

    Texas Floods Fatalities; Children Missing From Summer Camp

    At least 32 people have died and dozens of children are missing in the Texas Hill Country after catastrophic flooding, with officials warning the casualty count will climb as forecasts call for more rain and the risk of further flash floods in the coming days.

    Among those unaccounted for were at least 27 campers from Camp Mystic, an all-girls summer camp along the Guadalupe River in Kerr County, officials said at a briefing. Storms on Saturday on the northwest fringes of the Austin metro area left at least two people dead in Travis County, with another 10 people missing.

  • Jurassic World Rebirth Opens to Huge $300M-Plus Globally

    Jurassic World Rebirth Opens to Huge $300M-Plus Globally

    The dinos have a new lease on life.

    Universal and Amblin’s Jurassic World Rebirth is coming in ahead of expectations at the Fourth of July box office to hatch a new era for the Steven Spielberg-created franchise. In North America, the holiday tentpole is on course to post an estimated five-day domestic opening of $141.2 million, including $85.4 million for the three-day weekend, according to Saturday’s estimates.

    That’s the fifth-best showing ever for the holiday, while the three-day gross would mark the fourth-biggest domestic opening of 2025 to date. That’s no small feat considering July 4 fell on a Friday this year, meaning many moviegoers were distracted by holiday outings on what’s normally a critical day for new films. To boot, the latest Jurassic World pic has received decidedly mixed reviews from both critics and audiences alike. But there’s no dismissing the power of the Jurassic brand, or the spectacle of seeing dinosaurs come to life on the big screen.

    Jurassic World Rebirth, the seventh title in the series, is roaring even louder overseas, where its estimated opening is $171.3 million.

    That puts the film’s global start at $312.5 million — the second-best of the franchise, as well as the second-best opening of the year to date, behind A Minecraft Movie.

    Heading into the holiday, the pic was eyeing a domestic opening in the $100 to $120 million range and $260 million globally. It opened on Wednesday, July 2, to get a jump on the long holiday weekend.

    Following the conclusion of the Jurassic World trilogy directed by Colin Trevorrow, Spielberg, Amblin and Universal went back to the drawing board and enlisted filmmaker Gareth Edwards (Rogue One: A Star Wars Story) to direct Rebirth from a script by original Jurassic Park screenwriter David Koepp.

    The film features an all new cast anchored by Scarlett Johansson, Mahershala Ali and Jonathan Bailey. The story follows an extraction team that races to an island research facility that factored into the original Jurassic Park (along the way, they discover a shipwrecked family). Now, the island is inhabited by the worst of the worst creatures that were left behind.

    Rupert Friend, Manuel Garcia-Rulfo, Luna Blaise, David Iacono and Audrina Miranda also star. Producers include longtime franchise stewards Frank Marshall and Patrick Crowley, with Spielberg and Denis Stewart exec producing.

    The first three Jurassic World pics all grossed north of $1 billion globally, and all opened higher than Rebirth domestically (comparisons are complicated by the fact that they were all there-day openings). At the same time, the latest film cost less to produce, or $180 million before marketing. In 2015, Jurassic World opened to a franchise-best $208.8 million, followed by $148 million for 2018’s Jurassic World: Fallen Kingdom and $145 million for 2022’s Jurassic World: Dominion, not adjusted for inflation.

    The first Jurassic Park, directed by Spielberg, opened to $47 million domestically in early June of 1993, not adjusted for inflation — a huge sum at the time.

    Also setting off fireworks at the box office is Brad Pitt’s F1: The Movie, which is now in its second weekend after opening to $57 million domestically, a stellar number for a racing film about Formula One.

    From Apple Original Films in partnership with Warner Bros., F1 is safely parked in second place domestically with an estimated $25 million to $26 million for the three days as it crosses the $100 million mark domestically (it has already cleared $200 million globally).

    Universal and DreamWorks Animation’s live-action How to Train Your Dragon, Pixar and Disney’s Elio and Sony’s 28 Years Later are expected to round out the top five domestically. Blumhouse and Atomic Monster’s ill-fated M3GAN 2.0 could fall off as much as 68 percent in its second weekend to come in seventh behind Mission: Impossible — The Final Reckoning.

    Numbers will be updated Sunday morning.
