This week’s Scientist of the Week is Grant Zazula, a paleontologist for the government of Yukon. He and a team debunked theories that over-hunting by early humans led to the disappearance of mastodons from the Arctic and Subarctic.

David Sanders from Purdue Univ. found that the Ebola virus could become airborne as it can enter cells that line the trachea and lungs under controlled laboratory conditions.
Mary Cushman and a team from the Univ. of Vermont College of Medicine discovered that people with blood type AB may be more likely to develop memory loss in later years than people with other blood types.
Justin Yeakel and a team used depictions of animals in ancient Egyptian artifacts to assemble a detailed record of the large mammals that lived in the Nile Valley over the past 6,000 years.
Calvin Miller and a team studying in Iceland found that conditions on Earth for the first 500 million years after it formed may have been surprisingly similar to the present day, not a hellscape as thought.
Sandi Carmen and a team from EPFL discovered that stress activates a cleaving enzyme in the brain that can lead to people being distracted, grumpy, forgetful and more.
Jurriaan de Vos and a team found that extinctions are about 1,000 times more frequent now than in the 60 million years before people came along.
Claire Sexton and a team from the Univ. of Oxford found that sleep difficulties may be linked to decline in brain volume.
Kristian Carlson and a team from Wits Univ. studying the Taung Child— South Africa’s premier hominin— have cast doubt on the idea that this early hominin shows infant brain development in the prefrontal region similar to that of modern humans.
Maurice Ohayon from the Stanford Univ. School of Medicine found that one in seven people suffers from sleep drunkenness.
Martin Smith and a team from the Univ. of Cambridge found how a mysterious, long-extinct worm-like creature with legs and spikes called Hallucigenia, fits into the evolutionary tree.
Therese O'Sullivan and a team from Edith Cowan Univ. found that eating higher amounts of cheese, milk, yogurt or butter does not make a person more likely to die from cardiovascular disease, cancer or any other cause.
Alan Feduccia and Stephen Czerkas found that a birdlike fossil, called a Scansoriopteryx, is not a dinosaur, as previously thought, but much rather the remains of a tiny tree-climbing animal that could glide. Their find challenges the commonly held belief that birds evolved from ground-dwelling theropod dinosaurs that gained the ability to fly.
Thomas Bosch and a team from Kiel Univ. have found that cancer has existed for as long as multi-cellular life.
Tim Kohler and a team from Washington State Univ. studied one of the greatest baby booms in North American history and shed light on the dangers of overpopulation.
Jeffrey Bada and a team from the Scripps Institution of Oceanography at UC San Diego analyzed samples of prebiotic materials created in 1958 by the famous chemist Stanley Miller.
John VandeBerg and a team from the Texas Biomedical Research Institute have established unequivocally, in a natural animal model, that the incidence of malignant melanoma in adulthood can be dramatically reduced by the consistent use of sunscreen in infancy and childhood.
Jon Major and a team from the Univ. of Liverpool found that a chemical used to make tofu and bath salts could also replace a highly toxic and expensive substance used to make solar cells.
Daniele Lantagne and a team found that the EPA’s recommendations for treating water after a natural disaster or other emergencies call for more chlorine bleach than is necessary to kill disease-causing pathogens, and are often impractical to carry out.
Kees Jan van Groenigen and Bruce Hungate found that increased levels of carbon dioxide in the atmosphere cause soil microbes to produce more carbon dioxide, accelerating climate change.
Donita Brady and a team from Duke Univ. found that drugs used to block copper absorption may find an additional use as a treatment for certain types of cancer.
Wieger Wamelink and a team from Wageningen Univ. discovered that Martian soil could, in theory, be used to cultivate crops.
By analyzing temperature data all the way back to 1500, Shaun Lovejoy from McGill Univ. all but ruled out the possibility that global warming in the industrial era is just a natural fluctuation in the Earth’s climate.
Verano-Braga and a team from the Univ. of Southern Denmark discovered that nanosilver can penetrate our cells and cause damage.
Thomas Junk and a team from the Univ. of Louisiana at Lafayette developed a method to turn fat from alligators and other animals into biofuel.
