Ancient DNA from 46 Lake Baikal hunter-gatherers revealed two early plague outbreak phases about 5,500 years ago, with Yersinia pestis detected in 18 individuals. The findings suggest these basal plague strains caused lethal, child-heavy outbreaks long before dense farming societies, cities, or classical flea-borne bubonic plague emerged.

Researchers created a DIA-MS atlas of 13,609 proteins across 2,856 samples from fetal, healthy adult, paired non-tumor, and tumor tissues. The resource maps tissue-specific protein patterns, cancer-associated changes, organ-specific drug-toxicity signals, and candidate therapeutic targets.

We’ve all been there: waking up feeling like a zombie despite getting eight hours of sleep. While wearables give us data, they often fail to give us foresight . What if you could predict your stress levels 24 hours in advance? 🚀 In this tutorial, we are going to tackle HRV prediction (Heart Rate Variability) using a state-of-the-art Temporal Convolutional Network (TCN) . By leveraging the Oura Ri…

Synthetic microbial communities give researchers controlled models for testing how diet reshapes gut microbial ecology, metabolism, and host-relevant responses. The review highlights how SynComs can strengthen causal inference, improve intervention testing, and support future precision nutrition, while noting major challenges in stability, standardization, and ecological realism.

Scientists studying unusual sharks that can “walk” along the seafloor have made an exciting discovery—a completely new species that was previously unknown to science. The newly identified shark, officially named Hemiscyllium dudgeonae and commonly called Dudgeon’s Walking Shark, lives only in a small area off the southeastern coast of Papua New Guinea. The species was […] The post Scientists disc…

Koalas survived a climate-driven population crash 100,000 years ago, and new genomic research is helping scientists better protect the species today. A major genomic study has transformed scientists’ understanding of koala (Phascolarctos cinereus) evolution, showing that the species underwent a dramatic population decline about 100,000 years ago, long before humans reached Australia. Researchers …

Benchmarking the Honesty of Fine-Mapping Credible Sets Fine-mapping has a promise built into its output, and almost nobody checks whether the promise is kept. When you run SuSiE on a GWAS locus, it hands you a credible set : a small group of variants that, at a stated confidence level like 95%, should contain the true causal variant. That 95% is a claim about reality. Among all the loci where SuS…

A massive new meta-analysis reveals that individual cognitive abilities, like reading and math, rely on inherited DNA just as much as overall intelligence, suggesting people possess heavily customized genetic cognitive profiles independent of general smarts.

A new study untangles the complex microbial history of Ötzi the Iceman, revealing which microorganisms originated during his lifetime and which arrived long after his death. For more than 5,000 years, Ötzi the Iceman has carried an invisible community of microbes through ice, time, and modern museum preservation. Now, scientists have taken the most detailed [...]

Researchers have identified a gene that appears to balance a powerful evolutionary trade-off, boosting growth and reproductive success early in life while carrying hidden costs later on. The biological processes that help build a healthy young body may also sow the seeds of aging and cancer. Researchers have now identified a gene that appears to [...]

Our genetic heritage is not a blueprint or an algorithm, as many biologists have imagined, but something else entirely.

Consanguineous marriages, defined as unions between biologically related individuals, remain prevalent in several regions of India due to cultural and social traditions.

A study of long-lived families has identified rare genetic variants that may help people stay healthier for much longer as they age. One standout mutation appears to temper inflammation, potentially delaying disease and extending years of healthy living.

Scientists at Baylor College of Medicine may have uncovered a promising new way to combat Alzheimer’s and Parkinson’s disease. Instead of trying to stop Tau and alpha-synuclein proteins from gathering into tiny droplets inside brain cells, the researchers found that tubulin—the protein that builds the cell’s internal transport network—can redirect these proteins away from forming toxic clumps and…

Scientists have found a promising way for astronauts to produce their own medicine when resupply from Earth is no longer possible.

The results show that effects of adversity are not solely cumulative and the type of adversity experienced may be uniquely related to mitochondrial function, the researchers said

Scientists have discovered microbes living thousands of feet underground in places once thought to be nearly uninhabitable.

New research reveals that while infants' brains process musical structure as early as three months old, their bodies take much longer to catch up. Structured physical movement to music doesn't emerge until closer to their first birthday.

The wellness industry loves biological 'clocks'. They're a way of using particular measurements in your...
