Few genomes have been sequenced from early modern humans, who first arrived in Europe when the region was already inhabited by Neanderthals. An international team has now sequenced the oldest modern human genomes to date. The genomes were recovered from seven individuals who lived between 42,000 and 49,000 years ago...

Canada should focus on building mass utility-scale solar mega-projects to kickstart its green energy transition, according to a new report. The recommendation comes from a new article which looks at the current state of solar power and compares the benefits of both mass-scale projects and smaller, decentralized approached like individual...

Researchers developed a non-invasive imaging technique that enables laser light to penetrate deeper into living tissue, capturing sharper images of cells. This could help clinical biologists study disease progression and develop new medicines.

A new study estimates that more than 9000 insects and other native invertebrates have become extinct in Australia since European arrival in 1788 and between 1-3 additional species become extinct every week.

Is it possible to pass on the effects of malnutrition? A new animal study found that a protein-deficient diet in one generation created related health risks -- lower birth-weight, smaller kidneys -- in offspring that lasted four generations.

Gut microbiome composition during pregnancy has long-term effects on offspring stem cell growth and development, researchers report. Treating pregnant mice with a common gut microbe resulted in offspring that had more active stem cells in both the brain and intestinal tract. As a result, the offspring were less anxious and...

Scientists' findings in mice could translate into a radical, needle-free vaccination approach that would also eliminate reactions including fever, swelling and pain.
