Scientists have discovered that marsupial forelimbs (arms) develop much earlier before birth than previously thought, providing new insights into evolutionary innovation and biology.

A German analysis explores what underlies shifts in the timing of seasonal surges of respiratory diseases, as well as shifts in surges of heart-related deaths, that occurred after the COVID-19 pandemic began. Michael Sieber and Arne Traulsen of the Max Planck Institute for Evolut

LMU researchers demonstrate that oxygenic photosynthesis can occur with only a single photosystem, overturning a fundamental principle of biology.

A night without sleep produced increased markers of connections between brain cells, showing that sleep in humans may be important for restoring cellular balance in the brain, according to a study published in PLOS Biology by David Elmenhorst from the Forschungszentrum Jülich Ins

Human fetal tissue research has contributed to advances in developmental biology, the study of congenital diseases, regenerative medicine and vaccine development. As it involves fetal tissue obtained following induced abortion, such research must be conducted with the utmost care

Every sunrise and sunset sends the body a signal, keeping the circadian clock running on a roughly 24-hour cycle. This clock evolved so organisms could adapt to Earth's daily rotation, syncing their biology to the pattern of day and night. Artificial lighting has freed human soci

Chronic psychological stress can help tumors evade immune attack through a chain of molecular events involving gut bacteria and viruses within those bacteria, according to a study led by Weill Cornell Medicine investigators. The findings unveil a new layer of cancer biology, alon

Studies of genetics conducted in yeast cells, human neurons, mice or other model systems often reveal networks of genes that could contribute to complex diseases, such as breast cancer, type 2 diabetes and Parkinson's disease. But those findings don't always translate to human bi

The environment experienced by young zebrafish influences both the shape and electrical activity of the neurons in the eye, which affects subsequent behavior.

A new study led by researchers at The University of Texas MD Anderson Cancer Center has identified a way to tailor drug combinations based on specific tumor biology to improve outcomes for treatment-resistant advanced melanoma.

A protein produced by gut immune cells orchestrates both immune protection against pathogens and immune tolerance of gut bacteria, according to a study led by Weill Cornell Medicine investigators. The discovery illuminates the complex biology of the gut immune system and could le

More than 50 million Americans live in counties without a radiation oncology practice site, and millions more are at risk, according to a new study published today in the International Journal of Radiation Oncology*Biology*Physics (Red Journal), the flagship journal of the Americ
