For The Better

Community structure, including relationships between and within groups, is foundational to our understanding of the world around us.

Hemoglobin is well known as the molecule in blood responsible for carrying oxygen around the body, but when fresh mouse blood is detected in the nose, the molecule also works as a chemosensory signal warning lactating mother mice to protect their young…

A long-term study finds significant changes in brain development linked to anxiety in children with autism. The study, which included brain scans and interviews, also provides new evidence that supports forms of anxiety specific to autism.

Scientists identified vulnerable site on multiple coronaviruses that could be targeted to prevent future pandemics.

Rural counties saw 2.4 times more COVID-19 infections per capita compared to urban counties in July and August of 2021 during a surge of the delta variant, a new study finds. Early data suggest omicron is spreading faster in urban areas but causing mor…

Caribou (known as reindeer in Europe) make one of the longest seasonal migrations of land animals, but an individual’s propensity to migrate depends on its genetic ancestry, researchers report.

Facing the challenging task of developing lightweight, high-strength ceramic materials, an engineer has turned to an unexpected collaborator for design inspiration: the knobby sea star from the tropical Indo-Pacific. By investigating the complex and hi…

The brain’s ability to clear a protein closely linked to Alzheimer’s disease is tied to our circadian cycle, according to new research. The research underscores the importance of healthy sleep habits in preventing the protein Amyloid-Beta 42 (AB42) fro…

Scientists have developed the first fully autonomous biohybrid fish from human stem-cell derived cardiac muscle cells. The artificial fish swims by recreating the muscle contractions of a pumping heart, bringing researchers one step closer to developin…

Decades of research has shown that limits on calorie intake by flies, worms, and mice can enhance life span in laboratory conditions. But whether such calorie restriction can do the same for humans remains unclear. Now a new study confirms the health b…

Researchers have learned more about the part of the brain that mediates satiation. This could help lead to better treatments for eating disorders and weight management.

Researchers found that sea urchin larvae exhibited ciliary responses to strong photoirradiation by swimming backward. As ciliary responses are difficult to detect in deuterostomes because they may be masked by more obvious muscular activities, identify…

New research has found the protein p53 plays a key role in epithelial migration and tissue repair. The findings could improve our understanding of the processes used by cells to repair tissues, and be used to identify interventions that could accelerat…

A recent study explains an essential component for proper mitochondrial function: The protein complexes MICOS and ATP synthase can communicate with each other. Researchers have uncovered an important mechanism that ensures efficient metabolic adaptatio…

A new study reveals how prenatal exposure to mixtures of commonly found metals can adversely affect fetal growth.

Asymptomatic COVID-19 cases are the bane of computer modelers’ existences — they throw off the modeling data to an unknown degree. A new approach explores using historic epidemic data from eight different countries to estimate the transmission rate an…

New research has found the first tangible evidence that the ancestors of some of Australia’s most venomous snakes arrived by sea rather than by land — the dispersal route of most other Australian reptiles.

Clean energy researchers have designed a molecule to boost the performance of lithium-oxygen batteries to give electric vehicles the same driving range as petrol-fueled cars. Lithium-oxygen batteries are aimed to deliver maximum energy density through …
