A new study challenges a decades-old explanation for how bacteria change direction, revealing that the process may be driven by active, energy-dependent forces rather than passive protein interactions. Scientists have identified a new way to explain how swimming bacteria change direction, offering fresh insight into one of the most closely studied molecular systems in biology. […]

Scientists Uncover Hidden “Second Layer” in Human DNA
A newly identified cellular system monitors subtle variations in genetic coding, hinting at a hidden level of control over how genes are expressed. Human DNA stores instructions for life in sequences built from just four nucleotides. Those instructions are read in three-letter groups called codons, and each codon tells the cell which amino acid to […]
Global Cobalt Supply Chain at Risk of Sudden, System-Wide Collapse, Study Warns
Cobalt sits at the heart of the clean energy transition, but this study suggests its supply chain is far more fragile than it appears. Cobalt plays a central role in lithium-ion batteries and electric vehicles, but its global supply chain faces growing systemic risks that extend well beyond isolated disruptions. A new study shows that […]

Neanderthals May Have Used Birch Tar As Ancient Antibiotic, Study Finds
A new study explores whether birch tar, long associated with Neanderthal toolmaking, may have served another purpose as well. In a new study from the University of Cologne, the University of Oxford, the University of Liège, and Cape Breton University in Canada, researchers recreated birch tar using techniques associated with Neanderthals and tested whether it […]
This Overlooked Brain Region May Hold the Key to Strength in Aging
A new study reveals an unexpected connection between physical strength and brain activity. A new study points to an unexpected player in healthy aging: a little-known structure deep in the brain that may help maintain physical strength over time. The findings suggest it may be possible to identify and address frailty before it develops. Scientists […]
