In a typical experiment, scientists use Crispr to alter a single gene. But in recent work with pig cells, Dr. Church and his colleagues used Crispr to alter 62 genes at once. The researchers hope that this achievement may someday make it possible to use pig organs for transplantation into humans.

Arlanpeko kobazuloan (Lemoa, Bizkaia) emakume-itxurako grabatuak dituen harri handi bat aurkitu dutela jakinarazi dute. Grabatuak duela 17.500 urte ingurukoak dira, eta haietako bat osorik dago. Aurkikuntza aparta da, orain arte ez baitute horrelakorik topatu penintsulan. Hala, era horretako artearen banaketa geografikoa eta kronologia osatzeko gakotzat jo dute.

Montañas jóvenes, glaciares, planicies heladas, diversidad de paisajes y rachas de viento por su atmósfera. Este es el panorama de Plutón que ofrecen los primeros resultados científicos del sobrevuelo que hizo la nave New Horizons sobre el planeta enano y sus satélites, que también presentan superficies complejas y extrañas rotaciones.

Aireko CO2a harrapatzeko material berri bat sortu dute ikertzaile korear batzuek. CO2a fisikoki harrapatzen duen material mikroporodun bat da abantaila handi bat du orain arteko antzeko materialen aldean: urak ez dio eragiten.

Can Earth’s ice ages be seen in the undulating fabric of the sea floor? Earlier this year, a pair of papers suggested that long-term cycles of glaciation and melting trigger pulses of lava that harden into sea floor hills. But now, a new study throws cold water on that hypothesis, finding that these climate-driven pulses…

Vast regions of near-empty space in the Universe are growing and shrinking, much as bubbles merge and separate in soapsuds, astronomers have discovered.

A new technique will help genetic-test users make more informed decisions about their health.

As described in the current issue of Science Translational Medicine, researchers have found that antioxidants as much as double the rate of melanoma metastasis in mouse models. The results align well with other recent research by the same groupfinding that antioxidant supplements hasten and aggravate the progression of lung cancer, the most common form of…
