Adults who meet recommended weekly physical activity levels have a lower risk of death, finds a US study published by The BMJ today.

The survival benefits are similar regardless of intensity of activity, although they are slightly higher for vigorous than light to moderate activity, the findings show.

The immune system protects our body from constant attack by viruses, bacteria, and other pathogens. Much of this protection is provided by hematopoietic immune cells, which are derived from the bone marrow and specialize in fighting pathogens. They include macrophages, which remove pathogens; T cells, which kill infected virus-producing cells; and B cells producing antibodies that neutralize pathogens.

Real-world mobile phone data suggests a decline in the number of trips people made per day began before state-level stay-at-home policies were implemented, and the decline was strongly correlated with a reduction of COVID-19 case growth in the 25 most affected counties across the USA, according to a modelling study published in The Lancet Infectious Diseases journal.

Stamp-sized device comprises a suite of clinical-grade sensors, including temperature and pulse oximetry

Device sits at the base of the throat to pick up vibratory signatures of breathing, coughing, swallowing

Since developing the device, researchers have tested it on more than 50 physicians, rehabilitation specialists and patients at Shirley Ryan AbilityLab and Northwestern Memorial Hospital

Researcher: 'We are already seeing clear vital sign differences collected by the sensor between patients with COVID-19 and healthy-matched controls'

While scientists still don't fully understand the diverse nature of RNA molecules, it is believed that the proteins binding to them, called RNA-binding proteins, are associated with many disease formation. A research led by biomedical scientists from City University of Hong Kong (CityU) has developed a novel detection method, called CARPID, to identify binding proteins of specific RNAs in the living cells. It is expected the innovation can be applied in various cell researches, from identifying biomarkers of cancer diagnosis to detecting potential drug targets for treating viral diseases.

PROVIDENCE, R.I. [Brown University] -- When picturing dinosaur tracks, most people imagine a perfectly preserved mold of a foot on firm layer of earth. But what if that dinosaur was running through mud, sinking several inches -- or even up to their ankles -- into the ground as it moved?

Using sophisticated X-ray-based technology, a team of Brown University researchers tracked the movements of guineafowl to investigate how their feet move below ground through various substrates and what those findings could mean for understanding fossil records left behind by dinosaurs.

MADISON, Wis. -- Showing people how their peers feel about diversity in their community can make their actions more inclusive, make members of marginalized groups feel more like they belong, and even help close racial achievement gaps in education, according to a new study.

Drawing on strategies that have worked in anti-smoking, safe-sex and energy-saving campaigns, University of Wisconsin-Madison researchers decided to try to change behavior by showing people that positive feelings about diversity are the norm.
