A hidden signature in sleep brain waves may quietly track how the brain ages. to develop dementia. The research, led by UC San Francisco and Beth Israel Deaconess Medical Center in Boston, used machine learning to analyze brain waves recorded overnight. The team focused on a measure called “brain age,” which is estimated from sleep […]
New Study Challenges Decades of Alzheimer’s Understanding With Microtubule Discovery
A new study suggests that two of Alzheimer’s disease’s most debated players may be more closely connected than they first appear. Alzheimer’s disease is the most common cause of dementia, but scientists still do not fully agree on what starts the damage. For years, the debate has centered on two major suspects: amyloid beta, which […]
New Drug Could Help Maintain Weight Loss After Ozempic and Wegovy
A new clinical trial is exploring a different strategy for tackling one of obesity treatment’s biggest challenges: keeping weight off after initial success. GLP-1 drugs such as Ozempic and Wegovy have reshaped how obesity is treated, but many patients struggle to maintain weight loss after stopping these medications. A new clinical trial led by George […]
Biologists Challenge 70-Year-Old Theory of How Bacteria Swim
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 […]
