T. rex took 40 years to reach full size, scientists find

Tyrannosaurus rex may have been a much slower grower than scientists realized. A new study of 17 tyrannosaur fossils found that the giant predator likely took about 40 years to reach its full size of roughly eight tons, extending previous estimates by 15 years.

One common fat may fuel type 2 diabetes while another helps fight it

Not all fats affect your body the same way. Researchers found that palmitic acid, a saturated fat common in many foods, may contribute to insulin resistance and type 2 diabetes by triggering inflammation, toxic fat buildup, and cellular stress. In contrast, oleic acid—the heart-healthy fat abundant in olive oil—appears to help protect insulin function and may even counter some of the harmful effects of palmitic acid.

Chinese sodium battery surprised scientists by matching key Tesla benchmarks

Researchers found that a Chinese sodium-ion battery performs far better than expected, with production quality and design features comparable to Tesla’s batteries. If engineers can improve cold-weather charging and energy density, sodium could become a cheaper and more abundant alternative to lithium for EVs and large-scale energy storage.

As lakes turn brown, trout and bass decline while pike and walleye thrive

Freshwater lakes across North America and Europe are becoming noticeably browner, reducing underwater visibility and reshaping fish populations. Research found that several popular sport fish, including trout, bass, perch, and whitefish, tend to decline in darker waters. Meanwhile, walleye and northern pike often become more abundant because they are better adapted to low-visibility conditions. The shift could change both lake ecosystems and the fishing experience for millions of anglers.

Tubulin prevents toxic brain protein clumps linked to Alzheimer’s and Parkinson’s

Scientists at Baylor College of Medicine may have uncovered a promising new way to combat Alzheimer’s and Parkinson’s disease. Instead of trying to stop Tau and alpha-synuclein proteins from gathering into tiny droplets inside brain cells, the researchers found that tubulin—the protein that builds the cell’s internal transport network—can redirect these proteins away from forming toxic clumps and toward healthy, productive work.

Yale study finds nearly half of older adults improved with age

A long-term Yale study is challenging one of the biggest myths about aging. Nearly half of adults over 65 improved physically, mentally, or both over time, despite the common belief that aging means constant decline. Researchers found that people with more positive attitudes about getting older were significantly more likely to show these gains.

Think human anatomy is finished? Scientists say think again

Despite centuries of study, scientists are still finding new details and even overlooked structures within the human body. As researchers explore anatomical differences between individuals, it’s becoming clear that the body is far more complex—and less fully understood—than textbooks suggest.

Scientists discover neurons must break their DNA to build the brain

As newborn neurons make their way through the developing brain, they must squeeze through incredibly tight spaces to reach their final destinations. Researchers discovered that this physical journey routinely causes some of the most severe forms of DNA damage—double-strand breaks—yet the young brain has evolved an impressive ability to repair the damage almost immediately.

Major review finds vaping likely causes lung and oral cancer

Researchers have concluded that nicotine vapes are likely to cause lung and oral cancers, based on evidence ranging from human biomarkers to animal and laboratory studies. The findings challenge the idea that vaping is a harmless alternative to smoking and suggest health risks may be emerging much sooner than many expected.

Scientists found a cannabis compound that relieves pain without the high

Compounds responsible for the aroma of cannabis and many other plants may offer a surprising new way to relieve chronic pain. Researchers found that several cannabis-derived terpenes significantly reduced pain in mouse models of fibromyalgia and post-surgical pain, with one terpene, geraniol, showing especially strong effects. Unlike THC, these compounds are not associated with psychoactive effects, making them a potentially attractive alternative for pain treatment.

Researchers warn that protecting battery supply chains will require system-wide coordination because critical bottlenecks can turn local shocks into global problems.

The first primates may have evolved in the cold, not the tropics

A surprising new study suggests the earliest primates didn't originate in tropical forests but in cold, dry parts of North America. Some may have even survived seasonal Arctic conditions by slowing their metabolism or hibernating. Researchers found that dramatic climate shifts, rather than warmth, played a major role in driving primate evolution and expansion. The discovery reshapes our understanding of how our own lineage began.
