A new study details more than 60 tools made of bone and one tool made from the tooth of a cetacean. These finds, first unearthed from Contrebandiers Cave, Morocco in 2011, are highly suggestive proxy evidence for the earliest clothing in the archaeological record and attest to the pan-African emergence of complex culture and specialized tool manufacture.

The ability to visualize cancerous tumors and metastatic tissue in three dimensions helps clinicians diagnose the precise type and stage of cancer. Now researchers have developed specialized hydrogels designed to rapidly remove fats from tissues, which are a factor in tissue opacification.

The experience of a fruit fly dying from cancer may seem worlds away from that of a human with a life-threatening tumor, yet researchers are discovering commonalities between the two that could reveal ways to improve the survival of cancer patients.

Researchers have developed a neutrophil-selective fluorescent probe, through metabolism-oriented live-cell distinction, that enables them to decipher live neutrophils, the most common white blood cell in humans.

Women with higher levels of the endocrine-disrupting chemicals per- and polyfluoroalkyl substances (PFAS) in their system may be 20% more likely to stop breastfeeding early, according to a new study.

Researchers at the University of Alabama at Birmingham have published a foundational study where they asked a simple question: Which mutations predominate when the SARS-CoV-2 virus that causes COVID-19 is grown in successive generations — called passages by virologists — in tissue culture?

Research shows how chronic arsenic exposure disrupts the body’s natural antioxidant defenses, which may contribute to the development of diseases such as Type 2 diabetes.

Scientists have discovered a way to fabricate tiny color-changing gas sensors using new materials and a high-resolution form of 3D printing. The sensors – responsive, printed, microscopic optical structures – can be monitored in real-time and used for the detection of solvent vapors in air.

Archaeologists have long had a dating problem. The radiocarbon analysis typically used to reconstruct past human demographic changes relies on a method easily skewed by radiocarbon calibration curves and measurement uncertainty. And there’s never been a statistical fix that works — until now.

In a new study, scientists provide the most detailed view of how human small ribosomal subunits are put together by capturing their 3D portraits at three different stages of the assembly process.
