Study shows how a woman’s brain reorganizes during pregnancy

Pregnancy triggers vast changes in a woman's body - hormonal, cardiovascular, respiratory, gastrointestinal, urinary, and more. And, as a new study reveals, the brain undergoes major changes too, some fleeting and others more enduring. Researchers said on Monday they have for the first time mapped the changes that unfold as a woman's brain reorganizes in response to pregnancy, based on scans carried out 26 times starting three weeks before conception, through nine months of pregnancy, and then ...

Scientists propose a new measure of flexibility for crystals

A study led by Professor Umesh V. Waghmare from the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) in Bengaluru has introduced a novel approach to quantify the mechanical flexibility of crystals. This research could transform the way materials are screened and designed, particularly in the field of Metal-organic frameworks (MOFs). Their paper, “Quantifying the intrinsic mechanical flexibility of crystalline materials”, presents groundbreaking insights on the origin of mec...

Sea otters get more prey and reduce tooth damage using tools

Humans are not alone in the use of tools. Chimpanzees, for instance, crack nuts with stones and use sticks to get at tasty termites. Dolphins are known to employ sponges to protect their beaks while foraging. And a Galapagos Islands finch uses cactus spines to dig grubs out of holes. Sea otters also are members of the animal kingdom's tool-wielding club. And a new study offers a fuller understanding of the tool use - utilizing rocks and other objects to break open hard prey - by these marine ma...
