Cutting Back 1 Amino Acid Increased The Lifespan of Mice Up to 33%
NEWS | 10 June 2026
In mice, limited intakes of one specific essential amino acid can slow the effects of aging and even extend their lifespan, research from the US shows. In this case, restricting dietary isoleucine appeared to deliver significant health benefits to the animals in the experiment. Restricting dietary isoleucine increased the lifespan and healthspan of the mice, reduced their frailty, and promoted leanness and glycemic control. "Very quickly, we saw the mice on the reduced isoleucine diet lose adiposity – their bodies got leaner, they lost fat," said Lamming.

A Lost World Almost as Big as Mars May Have Once Orbited Our Sun
NEWS | 10 June 2026
Our Solar System may once have housed an extra world that no longer exists. This long-lost world may have been almost as big as Mars, before it suffered a cataclysmic end. Around 4.56 billion years ago, our fledgling Solar System resembled a demolition derby of explosively colliding rocks and untold planetary bodies. "It points to a distinct and separate evolutionary path in planetary formation in the early history of our Solar System." Upper-range estimates suggest the APB may have been even bigger, around 3,300 kilometers in radius, or a bit smaller than Mars (3,390 kilometers).

A Commonly Used Sleep Aid May Have a Dangerous Side Effect
NEWS | 10 June 2026
Here, Fauska and colleagues conducted a small clinical trial to assess its effects in people with obstructive sleep apnea, the most common type. Obstructive sleep apnea and insomnia often appear together, but crucially, around 80 percent of people with the sleep apnea condition are thought to be undiagnosed. People with sleep apnea may wake often or struggle to stay asleep, which can make their symptoms difficult to pick apart from insomnia. The researchers also point to growing evidence that there's no one-size-fits-all treatment for obstructive sleep apnea.

Scientists Identify The World's Biggest Known Scorpion, The Size of a Dog
NEWS | 10 June 2026
After an extensive new fossil study, researchers in the UK have confirmed the identity of Praearcturus gigas, which may be the largest known scorpion in history. Fossils from Canada studied in 2015 and belonging to the ancient scorpion Eramoscorpius were also referenced in this new work, with anatomy comparisons used as evidence that P. gigas is indeed also a scorpion. "Without complex ecosystems to support Praearcturus on land, these animals probably spent part of their lives hunting in water," says Howard. They would have had large forests to roam through, and many more land animals to meet (and eat). Further studies and fossil analysis should help add more detail to the timeline in the future, now we've established that P. gigas is indeed a scorpion.

Scientists Reveal The Optimal Amount of Strength Training For a Longer Life
NEWS | 10 June 2026
Chan School of Public Health analyzed data from 147,374 people across three long-running prospective cohorts: the Health Professionals Follow-up Study, the Nurses' Health Study, and the Nurses' Health Study II. The study team says the findings answer some important questions specifically about strength (resistance) training. For combined aerobic exercise and strength training, the largest reduction in mortality risk was seen in people doing 30–44 MET-hours of aerobic exercise per week plus 60–119 minutes of strength training. "Importantly, we observed that while either sufficient aerobic or resistance training alone reduced mortality risk, aerobic activity conferred greater benefit." Around one to two hours may be enough to see meaningful benefits, and blending strength training with aerobic training seems to be the best way of making sure you live longer – alongside a host of other factors.

We Surveyed Scientists About Aliens. Their Answers Were Revealing.
NEWS | 10 June 2026
These views may be insightful, but they rarely tell us what the wider scientific community thinks. Shortly after the two major announcements of possible extraterrestrial life in 2025, we surveyed astrobiologists to understand how expert judgment was distributed across the field. For K2-18b, only 6.6% of surveyed astrobiologists agreed that scientists had probably found extraterrestrial life. The proportion of astrobiologists who strongly disagreed fell dramatically, from 35.1% in the K2-18b case to just 11.1% for Mars. Likewise, movement from strong disagreement towards ordinary disagreement may signal a softening of attitudes even when overall disagreement remains high.

Your Cat Can Bring Home More Disease Than You Think. Here's What to Do.
NEWS | 10 June 2026
We are ecologists and a veterinarian who study wildlife health and the movement of pathogens among wildlife, domestic animals and people. If you let your cat outdoors, or if outdoor cats visit your yard, our recent findings may be relevant. Humans share more zoonotic pathogens with domestic animals than with wildlife, because domestic animals live close to us. One study estimated that outdoor cats deposited more than 60 tonnes of feces per 10,000 households each year. The free-roaming debate is often framed as a false choice: either cats roam freely, or they are deprived of a natural life.

Don't we already have Ebola vaccines? Yes, we have two approved Ebola vaccines. However, this is a different virus to the one circulating in the DRC and Uganda currently, the Bundibugyo Ebola virus. If successful, the experts noted a single dose could be suitable for contacts of Ebola cases. This group has already produced vaccines against another type of Ebola virus that has been tested in early phase human clinical trials.

Scientists Found 2 Existing Drugs Could Reverse Alzheimer's Brain Damage in Mice
NEWS | 10 June 2026
Scientists looking to combat Alzheimer's disease may have found two promising candidates. The team of US researchers started by investigating how Alzheimer's altered gene expression in the brain. When used in tandem, the drugs were shown to reverse some of the brain changes brought on by the disease. By combining the two drugs, the researchers were able to target different types of brain cells affected by the disease. One of the next steps should be clinical trials for people with Alzheimer's disease.

Hail Is Changing, And Scientists Warn It Could Become More Dangerous
NEWS | 10 June 2026
That means winter crops like wheat may see increasing risk, while risk may decrease for summer crops like maize. If climate change shifts arable regions closer to the poles, these crops may be subjected to increased hail frequency there. Both studies show increasing hail risk with increased frequency and hail damage potential in the mid-high latitude northern hemisphere and southeastern South America. In sub-tropical regions of Africa and northern South America, both studies show decreasing hail risk. Quickly reducing greenhouse gas emissions is the surest way to blunt the most damaging effects of climate change.

Strange Stars Look Suspiciously Like They've Been Eating Planets

Astronomers therefore have to hunt for subtler clues – chemical traces, unusual stellar behavior, and other lingering signs of cosmic chicanery. Red dwarf stars are not stars at the end of their lifespans. If a cluster red dwarf star has lithium crumbs, and its siblings do not, it warrants a closer look. We know that small rocky planets are common around red dwarf stars, and that some stars can devour their planets. This finding suggests that red dwarf stars may offer a new way to investigate this phenomenon that reveals the mechanics of system formation.

The Tragic Case of The Youngest Person Ever Diagnosed With Alzheimer's
NEWS | 10 June 2026
Alzheimer's disease is most commonly diagnosed in older adults, but that doesn't mean the condition can't strike earlier in life. In 2022, neurologists at a memory clinic in China diagnosed a 19-year-old with what they believed to be a probable case of Alzheimer's – making him the youngest person ever to be diagnosed with the condition. "This is the youngest case ever reported to meet the diagnostic criteria for probable Alzheimer's disease without recognized genetic mutations," neurologist Jianping Jia and colleagues write in their study. Before this diagnosis in China, the youngest patient with Alzheimer's was 21 years old. The study was published in the Journal of Alzheimer's Disease.

A Common Vitamin Has a Complicated Link to Cancer, Experts Reveal
NEWS | 10 June 2026
Vitamin B12 is one of those vitamins. Its role in synthesizing and stabilizing DNA is at least partly what led scientists to investigate a link with cancer. But other studies muddied the waters – showing a link between unusually high levels of B12 in the blood, and lung cancer. Researchers are still trying to untangle exactly what these elevated B12 levels mean. A 2022 review of human studies concluded there still isn't strong evidence that high B12 intake, high B12 levels, or supplementation directly cause cancer, despite repeated associations between abnormal B12 levels and disease.
