Can DNA traces in just two liters (0.5 gallons) of water reveal how a river's biodiversity changes over the course of a year? A study by the University of Duisburg-Essen using the River Lippe as an example shows how biodiversity ...
The adult human brain has limited capacity to repair or regenerate neurons lost to Alzheimer's disease, the most common type of dementia. Existing treatments can slow disease progression but do not reverse cognitive decline. ...
Bats are anomalies in the mammalian world—they fly, have long lifespans and rarely get cancer. Scientists now suspect the bat immune system enables them to live longer without disease, according to a new study published today ...
Scientists at the Department of Energy (DOE)'s Oak Ridge National Laboratory (ORNL) have shown that more than 93% of possible E. coli CRISPR-Cas9 guide RNAs—molecules that direct the gene-editing CRISPR tool to the right ...
The next time you need to freshen up the paint on your house or apply a bit of cosmetic glitter before heading out for the night, you might want to give a quick nod to the butterflies fluttering in a nearby garden. Taking ...
The European flat oyster (Ostrea edulis) was once widespread but has now become so scarce in the North Sea that it no longer forms ecologically functioning reefs. Along with the demise of the flat oyster, the three-dimensional ...
Scientists have recently reconstructed the ancestral karyotype of the banana family, revealing how chromosome numbers decreased stepwise from 17 to 9–11 over evolutionary time.
