Optimal breeding group sizes differ by sex in cooperative animals

Research on ostriches found that optimal breeding group sizes vary depending on the balance of males and females within it. The study showed that males have a single optimal group size, while females have multiple optimal sizes due to cooperative care. Intermediate-sized groups were not optimal for reproductive success in either sex.

New insights into tumor biology

A recent study reveals that cancer cells adopt a softer state to facilitate metastasis, forming a new mechanical state with rigid islands in a fluid environment. This state allows tumors to grow while providing room for soft, motile cells to break out and form metastases.

Apple MacBook Pro 14-inch (M4 Pro) powers local ML workloads, large datasets, and multi-display analysis for field and lab teams.

Mouse study explores Alzheimer’s link to the X chromosome

A mouse study found that female brains express higher levels of an X-linked enzyme called USP11, leading to greater accumulation of tau protein and increased vulnerability to Alzheimer's disease. The results suggest that excessive activity of USP11 drives this increased susceptibility in females.

Uncovering the secrets of materials degradation in lithium-ion battery

Researchers at KIST have successfully observed the expansion and deterioration of anode materials due to lithium ion migration, revealing a new understanding of the process. The study suggests that appropriately distributing micro- and nano-sized pores can alleviate volume expansion and improve safety in high-capacity anode materials.

Lack of naloxone led to increased overdose deaths in rural Pa., study finds

Researchers found that individuals who received naloxone were nine times more likely to survive an overdose, but access to the drug varied greatly across counties. The study suggests that increasing distribution of naloxone, training emergency responders, and expanding take-home programs could help combat the opioid epidemic.

Increasing evidence that bears are not carnivores

Researchers have found that captive bears prefer a high-carbohydrate, low-protein diet, which is different from the typical high-protein diet they receive in zoos. This dietary preference is consistent with the bears' natural diet in the wild and may contribute to their shorter lifespan in captivity.

Satellites capture massive drainage of proglacial lake in remote Patagonia

Researchers from Hokkaido University used satellite images to observe the sudden drainage of proglacial lake Lago Greve in Chilean Patagonia, resulting in a 18-meter drop in water level and a loss of 3.7 cubic kilometers of water. The study suggests that the cause was the collapse of a sediment bump at the lake's outlet, highlighting t...
