Warm oceans helped first human migration from Asia to North America

Warmer Pacific Ocean currents during the ice age may also have supported early human settlements. New research reveals significant changes in the circulation of the...

Coronavirus mutation – not as scary as it sounds

A new strain of the coronavirus may be responsible for the faster spread of the virus in London and south-east England, it has been...

Mass extinctions happen every 27 million years, says study

Timing of mass extinctions lines up with asteroid impacts and massive volcanic eruptions. The cycle of mass extinctions of land-dwellers—including amphibians, reptiles, mammals, and birds—coincide...

Scientists 3D print biomedical parts with supersonic speed

Forget glue, screws, heat or other traditional bonding methods. A Cornell University-led collaboration has developed a 3D printing technique that creates cellular metallic materials by...

Where does water on rocky planets come from

The emergence of life is a mystery. Nevertheless, researchers agree that water is a precondition for life. The first cell emerged in water and then...

Coronavirus mutation may have made it more contagious, shows study

A study involving more than 5,000 COVID-19 patients in Houston finds that the virus that causes the disease is accumulating genetic mutations, one of...

Like it or not, Joro spiders are here to stay

Chances are, if you live in northeast Georgia you’ve come across an East Asian Joro spider this fall. At almost 3 inches across when their...

Scientists find how common mutation leads to ‘night owl’ sleep disorder

A new study by researchers at UC Santa Cruz shows how a genetic mutation throws off the timing of the biological clock, causing a...

Scientists discover dozens of new COVID-19 related genes

Researchers screened hundreds of millions of cells exposed to the COVID-19 and MERS viruses and identified dozens of genes that both enable the viruses...

Ancient elements buried in our DNA could activate immune response to kill cancer

Ancient embedded elements in our DNA from generations past can activate a powerful immune response to kill cancer cells like an infection. The work builds...
