Scientists say the human family tree may need a major rewrite

The human family tree may be due for a major rewrite. Researchers argue that Australopithecus and Paranthropus should be folded into the genus Homo because new fossils have blurred many of the traits once used to separate them. The proposed shake-up could provide a simpler, more accurate picture of our surprisingly complicated evolutionary past.

Researchers reveal deeper workings of brain’s information hub

The brain has a remarkably flexible system for handling uncertainty and changing situations. Researchers found that the frontoparietal cortex constantly shifts how it communicates with other brain regions depending on what information is needed to make a decision. Rather than simply becoming more active when things get difficult, this network appears to reorganize itself in real time.

Scientists uncover the hidden nerve network fueling breast cancer

Researchers have uncovered a surprising way triple-negative breast cancer may turn the body against itself. Tumors appear to recruit macrophages—immune cells normally involved in healing and fighting infection—and use them to release a protein called BDNF that draws nerves into the tumor. Those nerves may then help the cancer grow, resist treatment, and potentially spread.

A 60-year-old theory about ants, bees and wasps may be wrong

Scientists have long thought an unusual genetic system helped ants, bees, and wasps evolve their extraordinary social colonies. A massive new analysis suggests that genetics alone can’t explain it—and the real secret may lie in other traits unique to these insects.

Scientists solve the mystery of a brain “switch” that can trigger weight loss in opposite ways

Scientists have uncovered why two seemingly opposite ways of targeting the same brain receptor can both promote weight loss. In mice, activating the GIP receptor in the brainstem reduced appetite, while blocking it in the hypothalamus removed a kind of “brake” on fullness signals. The discovery helps explain why very different obesity drugs can achieve similar results and suggests that carefully combining GIP-targeting treatments with GLP-1 drugs like those related to Wegovy and Ozempic could produce stronger effects.

Scientists discover the brain has a fast lane and slow lane for clearing waste

AI has helped scientists measure the brain’s hidden cleaning system, revealing that fluid moves rapidly around its outer spaces but about 50 times more slowly through deep tissue. The discovery could eventually help researchers detect circulation problems linked to Alzheimer’s, aging, and concussions.

Exercise may help the aging brain “take out the trash”

Regular exercise may help the brain clear away harmful waste that can build up with age. Researchers found that physical activity supports several processes linked to the brain’s glymphatic cleanup system, including better sleep, lower inflammation, and healthier blood vessels. Because this waste-removal system becomes increasingly important as we get older, exercise could play a meaningful role in protecting against cognitive decline.

Cassini reveals a surprising twist in Saturn’s magnetic shield

Cassini data has revealed a surprising twist in Saturn’s magnetic shield: the planet’s rapid rotation appears to drag a key opening in its magnetosphere far toward the afternoon side instead of keeping it near noon, as happens on Earth. The finding confirms that giant planets like Saturn operate under a fundamentally different magnetic regime, where fast spin and charged material from moons such as Enceladus can overpower the Sun’s influence.

Dinosaurs became giants — so why did they never become tiny?

Dinosaurs conquered the land at enormous sizes, but strangely, they almost never evolved into truly tiny animals. New research suggests that physiology alone can’t explain this missing miniature end of the dinosaur spectrum—and that early mammals may have been partly responsible. While dinosaurs kept mammals from becoming large, small mammals may have returned the favor by occupying ecological niches that could otherwise have supported mouse-sized dinosaurs.

A protein older than blood circulation could transform cancer immunotherapy

A protein that evolved long before the human circulatory system may help unlock stronger cancer treatments. When C3 is produced inside tumors, it blocks immune-suppressing cells and gives immunotherapy a better chance to work. Researchers were even able to recreate this effect in resistant tumors, significantly improving survival in mice.

Teen cannabis use linked to slower memory and thinking growth

Teens who start using cannabis may experience slower growth in memory, attention, language, and processing speed. Their abilities often developed normally at first, then began leveling off while nonusers continued improving. THC appeared to be the most likely driver, especially for worsening memory.

Giant waves are sweeping Mars’ atmosphere into space

The solar wind may be stripping away Mars’ atmosphere by creating giant rolling waves along its outer edge. Data from MAVEN and Tianwen-1 show that these waves form plasma clouds that carry atmospheric particles into space. The process is concentrated on one side of Mars and may have played a major role in drying out the once potentially habitable planet.
