Scientists just found a way to store massive data using light in 3 dimensions
A new holographic storage technique uses light in three dimensions to dramatically increase how much data can be stored. It encodes information throughout a material using amplitude, phase, and polarization, rather than just on a surface. An AI model then reconstructs the data from light patterns, simplifying the process. This could pave the way for faster, denser, and more efficient data storage systems.
World's smallest QR code, smaller than bacteria, could store data for centuries
Scientists have created a microscopic QR code so tiny it can only be seen with an electron microscope—smaller than most bacteria and now officially a world record. But this isn’t just about size; it’s about durability. By engraving data into ultra-stable ceramic materials, the team has opened the door to storing information that could last for centuries or even millennia without needing power or maintenance.
New cholesterol guidelines could change when you get tested
A major new U.S. cholesterol guideline is shifting the focus toward earlier, more personalized prevention of heart disease. It urges people to start screening sooner—sometimes even in childhood—and highlights the importance of tracking not just LDL (“bad”) cholesterol but also genetic risk factors like lipoprotein(a). A new, more advanced risk calculator now uses broader health data to better predict heart attack and stroke risk over decades.
What teens eat could be affecting their mental health more than we thought
What teens eat might matter more for their mental health than previously thought. A sweeping review of nearly 20 studies found that healthier diets are often linked to fewer depressive symptoms, while poor eating habits may go hand in hand with greater psychological distress. Interestingly, focusing on whole dietary patterns—not just individual nutrients—showed more consistent benefits, suggesting that overall eating habits could play a meaningful role during this critical stage of brain development.

Glasgow's Smith relishing business end of season at Scotstoun
Glasgow Warriors' bonus-point win over Benetton could prove "massive" in their pursuit of a top-two finish, according to Ollie Smith. Warriors trailed 10-7 at the break after a scrappy first half at Scotstoun, but they delivered a strong response to run out 31-10 winners and strengthen their place at the top of the URC table. "We've set ourselves up in a good position all season, top of the log in the URC and up there in the Champions Cup as well," full-back Smith told BBC Scotland.

Solar cells just did the “impossible” with this 130% breakthrough
A new solar breakthrough may overcome a long-standing efficiency barrier. Researchers used a “spin-flip” metal complex to capture and multiply energy from sunlight through singlet fission. The result reached about 130% efficiency, meaning more energy carriers were produced than photons absorbed. This could lead to much more powerful solar panels in the future.
This new carbon material could make carbon capture far more affordable
Scientists have created a new kind of carbon material that could make carbon capture much cheaper and more efficient. By carefully controlling how nitrogen atoms are arranged, they found certain structures capture CO2 better and release it using far less heat. One version works at temperatures below 60 °C, meaning it could run on waste heat instead of costly energy. The discovery offers a powerful new blueprint for next-generation climate technology.
Canadian business stalls over US trade deal jitters
STORY: The Canadian manufacturing hub of Windsor is home to thousands of small and specialized part makers and caters primarily to car companies and equipment manufacturers. The city thrives on close integration with Detroit, America's automotive capital, just across the river.That means it's also on the frontline of tariff and trade uncertainty with Canada's largest trading partner. JACKIE RAYMOND: "Even if we don't directly work with the automotive industry, we indirectly do."Jackie Raymond is co-owner of FASTSIGNS, a Canadian company that designs and installs custom business signs and graphics.The company is coming off its toughest year since the pandemic. Orders from its core automotive clients dried up.And while a new project brought some relief, the company says customers are placing smaller orders, demanding longer payment terms, and bargaining harder on prices.:: FileIt all points to uncertainty tied to the United States-Mexico-Canada Agreement, which is up for review this year. It's a deal U.S. President Donald Trump has repeatedly said he could scrap.:: Washington, D.C. / December 2, 2025TRUMP: "...and we'll either let it expire or we'll maybe work out another deal with Mexico and Canada...":: FileThe agreement - known as CUSMA north of the border - exempts most Canadian goods from U.S. levies.While Mexico has started formal negotiations with the U.S. over the deal's renewal, Canada has so far only held informal talks.RAYMOND: "I think the CUSMA is very, very important because it trickles down to every little business right down to your barber shop and your nail shop, which will affect all of our customers."The situation in Windsor reflects a broader unease facing Canada's economy, which contracted 0.6% in the fourth quarter. About 90% of the city's exports cross the border, often multiple times during production.Manufacturing accounts for nearly a quarter of employment in the Windsor-Essex region.Its chamber of commerce, which represents about 750 businesses, says companies paused investments, delayed production, and cut jobs at the height of the tariff uncertainty last year. :: FileWindsor partly regained its footing as Trump exempted USMCA-compliant exports from Canada from tariffs in March last year.But uncertainty still drags on business confidence and Windsor's unemployment level remains one of the highest among major cities in Canada.Local shops complain of lower traffic and restaurants report thinner crowds.And builders say the housing market – often among the first sectors to show strain from the knock-on effects of tariff uncertainties – is near a standstill.Brent Klundert of BK Cornerstone, a local real estate builder, said he laid off 13 of his 21 staff as sales and prices slumped last year. "And you know, when people are going to make the biggest investment of their life, they really want confidence in their job, in the longevity of their job in the economy itself. And people lost that due to the tariffs.” // “If we can get through CUSMA, if we can get through our trade agreements with the US, I think that that will add a lot of confidence into the marketplace that we've been lacking.”Since January Klundert has rehired 10 of his employees, hoping homebuyers would start coming back.So far, only a few have.

Popular sugar substitute linked to brain damage and stroke risk
A widely used sugar substitute found in everything from keto snacks to diet drinks may not be as harmless as it seems. New research shows that erythritol can disrupt brain blood vessel cells, reducing their ability to relax, increasing harmful oxidative stress, and impairing the body’s ability to break down clots. These changes create conditions that could raise stroke risk, even at typical consumption levels.

Glyphosate: A story of science, risk, and nuance
In the summer of 2014, a California groundskeeper named Dewayne Johnson started noticing patches of raw, weeping skin spreading across his body. He had spent years applying Roundup, Monsanto’s glyphosate-based herbicide, for a school district, sometimes drenched in it when equipment malfunctioned. By 2014, he had a diagnosis: non-Hodgkin’s lymphoma. In 2018, a jury awarded him $289 million in damages, later reduced on appeal. Tens of thousands of lawsuits followed. The story hasn’t quieted down. It’s all over the internet, swinging between “this will kill you, buy organic” and “relax, you’re fear-mongering.” Some of that recent chatter stems from an Executive Order protecting glyphosate and its production, which set off intense infighting within the MAHA movement. Some of it reflects a deeper truth: Americans genuinely care about harmful chemicals in their environment (see poll below). And the conversation isn’t going anywhere, with a Supreme Court case involving Monsanto set for this April. Glyphosate (the active ingredient in Roundup) is one of the most widely used herbicides in the world. But does glyphosate cause cancer? And how much exposure is actually risky? With so much mistrust in institutions and corporations (and some genuine conflicts of interest), making sense of the actual scientific evidence is genuinely hard. Here is a translation of what the scientific evidence actually says. Does glyphosate cause harm? Glyphosate is an herbicide that kills most plants it contacts rather than targeting specific species. It works by blocking an enzyme pathway (EPSPS) that plants and many microorganisms need to produce essential amino acids. Without those amino acids, the plant can’t grow and dies. Glyphosate was first developed by Monsanto in the 1970s and became ubiquitous after the company introduced “Roundup Ready” crops in the 1990s. In 2024, Bayer removed glyphosate from residential Roundup-branded products due to litigation pressure. But today it is still the most widely used herbicide in the world. Farmers also discovered they could spray it directly on crops like oats, lentils, beans, and peas just before harvest to dry them out faster and make harvesting easier. Because of its widespread use, it’s obviously really important to understand if it’s harmful to humans. The key principle: The dose makes the poison The most important concept in toxicology is that “the dose makes the poison.” Sixteenth-century physician Paracelsus articulated what remains the foundational principle of toxicology: sola dosis facit venenum. Water will kill you if you drink enough of it. Aspirin saves lives at 81 milligrams and causes internal bleeding at higher chronic doses. So, at what dose is glyphosate poisonous? The LD50 in rats (the dose that kills half the test animals) is around 5,600 mg/kg body weight. Table salt is roughly 3,000 mg/kg. By that classic measure, glyphosate is less acutely toxic than salt. But some people are exposed to a lot of glyphosate through their work. And among the general public, there are many questions about low-dose, cumulative exposure from multiple sources over long periods. Does glyphosate cause health problems? Cancer Correlation maps are striking, with one analysis finding that 60% of counties that spray the most glyphosate have non-Hodgkin’s lymphoma rates above the national average. But correlation alone doesn’t establish cause, which is why animal and human studies matter. In animals: Rat studies are typically what most fear is rooted in, but most people don’t know the study details on the dosage given to rats. A pooled analysis of the 13 most rigorous rat studies found evidence that very high doses, around 55,000 times greater than typical food residue exposure, can cause certain cancers. In humans: One of the strongest studies followed 55,000 herbicide users over 20 years and found no overall increased cancer risk. There was one signal: among those with the highest use, rates of acute myeloid leukemia (AML) appeared elevated. A broader meta-analysis of 18 human studies also found no overall cancer risk, though a separate meta-analysis focused specifically on non-Hodgkin lymphoma found that people with high cumulative glyphosate exposure faced a 41% higher relative risk compared to those with low or no exposure. These human studies are observational studies (randomized controlled trials would be unethical), and meta-analyses are only as reliable as the studies they pool. But the story seems consistent: at very high exposure levels, there may be some cancer risk. But that’s about as far as the science currently takes us. Emerging research: gut and reproductive health Gut: Because glyphosate targets a pathway that exists in some gut bacteria, scientists have questioned whether it could affect the microbiome. In mice, a 2023 University of Iowa study found that glyphosate altered gut bacterial composition and raised markers of intestinal inflammation. A 2024 systematic review found similar patterns: disrupted gut bacteria and problems with the mucus layer that protects the intestinal wall in mice. Whether this translates to humans is an open question. The human gut is highly variable and resistant, and we don't yet have strong studies confirming the same effects in people. Reproductive health: Animal studies have found that glyphosate-based herbicides can interfere with reproductive hormones, including disrupting egg cell development in mice and reducing the number of eggs available in sheep’s ovaries. However, the doses used in these experiments were high, so it’s not yet clear whether the same effects would occur in humans. On the human side, a 2021 pilot study led by Mount Sinai researchers tested urine samples from pregnant women across the U.S. and found glyphosate in 95% of them. The study also found a possible connection between higher glyphosate exposure during pregnancy and a subtle physical difference measured in female newborns. That said, some connections weren’t statistically reliable and this was a small study. The researchers themselves said more and larger studies are needed before drawing firm conclusions. What do regulators say about glyphosate safety? In 2015, the International Agency for Research on Cancer (IARC), part of the World Health Organization, classified glyphosate as "probably carcinogenic to humans" (Group 2A). The classification is worth taking seriously. But, there’s an important distinction: IARC classifies hazard, meaning the potential to cause harm under some conditions. It does not assess risk, which accounts for actual exposure levels and the real-world probability of harm. The U.S. EPA, the European Food Safety Authority, Health Canada, and regulatory agencies in Australia and Japan have all concluded that glyphosate is “unlikely to be carcinogenic to humans” at realistic exposure levels. They’re asking a different question: given how much of this people actually encounter, what is the probability of harm? Your actual exposure is what determines your actual risk. What does glyphosate mean for your daily life? At the grocery store: Food residues are small. The EPA’s acceptable daily intake is 1.75 mg/kg of body weight per day. To hit that threshold from oatmeal alone, a 150-pound adult would need to eat roughly 50 pounds of oats every day. But this calculation addresses only one pathway (food), and we don’t yet have robust tools to measure people’s actual total exposure. If reducing exposure matters to you, organic certification prohibits synthetic herbicides, and organic oat products generally test at lower or undetectable levels. Either way, a diet rich in whole grains, conventional or organic, is far better for your health than one that omits them out of fear of residues. On the farm: Occupational exposure is orders of magnitude higher than consumer exposure. Farmers and farm workers who mix, load, and apply glyphosate-based herbicides, especially without protective equipment, face meaningfully different risk profiles. Proper PPE isn’t optional. Integrated weed management strategies that rotate chemical modes of action are also worth taking seriously, both for health and for long-term effectiveness. If you live near a farm: Spray drift is real. Concentrations near field edges can spike during and after application, particularly on windy days. This is an area where I think public health could really step up and empower rural communities with buffer zones, rather than placing the onus on individuals. But for now, knowing your local agricultural calendar and keeping windows closed during application are the first steps. Bottom line Dewayne Johnson was exposed to glyphosate at levels most people will never encounter, and a jury decided he deserved compensation. That outcome is not evidence that the oatmeal in your pantry is dangerous. But it is a reminder that the dose, the context, and the person doing the exposing all matter enormously. Glyphosate is a chemical tool with benefits, trade-offs, and genuine open scientific questions. Learning to hold that complexity without collapsing into panic or dismissal is, honestly, one of the most useful and hardest things to do in navigating modern health science.
