HANOVER, N.H. – Surface meltwater draining through and underneath Greenland’s tidewater glaciers is accelerating their loss of ice mass, according to a Dartmouth study that sheds light on the relationship between meltwater and subglacial discharge. The findings appear in the journal Annals of Glaciology. A PDF is available on request. Greenland has the potential to […]
Visitors to national parks are half as likely to see wolves in their natural habitat when wolf hunting is permitted just outside park boundaries. That’s the main finding of a paper co-authored by the University of Washington appearing April 28 in the journal PLOS ONE. Its authors examined wolf harvest and sightings data from two […]
Latest analysis shows that human limbs share a genetic programme with the gills of cartilaginous fishes such as sharks and skates, providing evidence to support a century-old theory on the origin of limbs that had been widely discounted. An idea first proposed 138 years ago that limbs evolved from gills, which has been widely discredited […]
Review of latest genetic evidence suggests infectious diseases are tens of thousands of years older than previously thought, and that they could jump between species of ‘hominin’. Researchers says that humans migrating out of Africa would have been ‘reservoirs of tropical disease’ – disease that may have sped up Neanderthal extinction. A new study suggests […]
