Remote sensing observations reveal the presence of ferric iron in the form of the mineral hematite at high latitudes on the Moon, possibly the product of reaction of ferrous iron on the Moon with oxygen from the Earth�s upper atmosphere.
UC scientists and physicians hope to permanently cure patients of sickle cell disease by using CRISPR-Cas9 to replace a defective gene with the normal version
The findings from Boyce Thompson Institute researchers could point the way to cost-effective, eco-friendly ways of enriching soil and reducing reliance on conventional fertilizers.
Encoding memories in engram cells is controlled by large-scale remodeling of the proteins and DNA that make up cells’ chromatin, according to an MIT study. This chromatin remodeling, which allows specific genes involved in storing memories to become more active, takes place in multiple stages spread out over several…
In an important step toward a fully implantable intracortical brain-computer interface system, BrainGate researchers demonstrated the first human use of a wireless transmitter capable of delivering high-bandwidth neural signals.
Analyzing a national cancer database, researchers find a bump in diagnoses at 65, suggesting that many wait for Medicare to kick in before they seek care.
Tooth loss is a widespread problem in adults and results in poor quality of life. Currently, solutions to this problem include artificial teeth and implants. But these aren’t as good as “real teeth,” and they don’t markedly improve quality of life. Now, scientists from Japan have made a discovery that can make…

We could reduce the amount of land used for grazing and croplands used to grow animal feed.
Can the current crop of vaccines get us to herd immunity even if variants become widespread? A Harvard immunologist says yes.
On December 8, 2016,* a high-energy particle called an electron antineutrino hurtled to Earth from outer space at close to the speed of light carrying 6.3 petaelectronvolts (PeV) of energy. Deep inside the ice sheet at the South Pole, it smashed into an electron and produced a particle that quickly decayed into a…
