The majority of plant seeds have the special ability to almost completely dry out and yet remain viable. While most living cells die with a 90% loss of water, cells in seeds enter a biological state of dormancy. With a moisture ...
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 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 ...
Climate change is reshaping global livestock production systems and leading to increased research on the topic. However, science still faces the challenge of translating advances in knowledge into practical solutions for ...
With the invasive emerald ash borer beetle decimating black ash across North America, according to the U.S. Forest Service, a team led by researchers at Penn State conducted an expansive study of genetic diversity in black ...
While extreme weather and habitat changes can spell doom for many native animals, including insects, a different picture has emerged from a new study led by Flinders University. Long-running investigations into Fiji's native ...
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.
