Nel Dna umano ci sono tracce di antenati fantasma – Biotech – Ansa.it

Scoperte nel genoma umano delle sequenze di Dna ereditate da antenati ‘fantasma‘ che si sarebbero incrociati con l’uomo moderno prima della sua dispersione fuori dall’Africa. Il risultato, pubblicato sulla rivista Science dai ricercatori dell’Università della California a Berkeley, dimostra che i rami del nostro albero evolutivo sono più intricati e…

A simple supplement could help the immune system fight cancer and viruses

Arginine is an amino acid that supports many essential functions throughout the body. It helps cells build proteins that carry out a wide range of biological processes. The body produces arginine naturally, and people also obtain it from many protein-rich foods. Abnormally low arginine levels have been linked to several…

Ancient Arctic carbon is pouring into the sea, but the seabed captures most of it

The Arctic’s frozen ground contains enormous stores of organic carbon. As permafrost thaws and coastlines erode, some of that carbon is carried into the ocean. There, microorganisms can break it down and release greenhouse gases that contribute to climate change. Until now, scientists have had limited information about how much…

Moonquakes could reveal hidden water beneath the lunar surface

Water buried beneath the moon may be detectable by listening to how vibrations move through the lunar ground. Researchers from the University of Maryland, Lawrence Berkeley National Laboratory and the University of Hawaii have found that seismic waves, the same type of vibrations scientists measure during earthquakes, could help locate…

Scientists reveal the hidden force driving the universe’s hottest fluid

When atomic nuclei crash into one another at nearly the speed of light, they briefly produce quark-gluon plasma, an extraordinarily hot state of matter in which quarks and gluons can move freely. This exotic material behaves like an almost perfect fluid and offers scientists a way to study conditions similar…
