A genetic tree as a movie: Moving beyond the still portrait of ancestry
Researchers have created a way to see your family tree as a movie rather than a still portrait by tracing where your ancestors moved across the globe over time. The statistical method can also be used to model disease spread and studying how animals move through geographic regions.
Melting ice, more rain drive Southern Ocean cooling
Researchers found increased meltwater and rain explain 60% of a decades-long mismatch between predicted and observed temperatures in the ocean around Antarctica.
Long COVID patients feel pressure to prove their illness is real, study finds
People living with Long COVID often feel dismissed, disbelieved and unsupported by their healthcare providers, according to a new study.
Cartilage and bone development: Three paths to skeleton formation
In vertebrates, the skeleton of different regions of the body arises from different precursor cells. Researchers have now discovered that these skeletal cells do not just differ in their developmental origin, but also in their gene regulation -- which may be a key to the vertebrates' evolutionary success story.
We must not ignore eugenics in our genetics curriculum, says professor
To encourage scientists to speak up when people misuse science to serve political agendas, biology professor Mark Peifer of the University of North Carolina at Chapel Hill argues that eugenics should be included in college genetics curriculums.
Park entrances may be hotspots for infective dog roundworm eggs
In an analysis of soil samples from twelve parks in Dublin, Ireland, park entrances were more heavily contaminated with infective roundworm eggs than any other tested park location.
Mini rolling robot takes virtual biopsies
A tiny magnetic robot which can take 3D scans from deep within the body, that could revolutionize early cancer detection, has been developed by researchers. The team say this is the first time it has been possible to generate high-resolution three-dimensional ultrasound images taken from a probe deep inside the gastrointestinal tract, or gut.
