Laboratory Equipment’s scientist of the week is Kay Tye from MIT. She and a team found that the desire for sugar and the urge to eat healthy foods are on separate neural circuits. This means that it might be possible to reduce the urge to eat unhealthy foods without impacting the drive to eat healthily when hungry.

This week’s scientist is Ian Armit. He and a team from the Univ. of Bradford definitively proved that climate change did not cause the huge population collapse in Europe at the end of the Bronze Age.
This week’s scientist is Robert Sclafani from the Univ. of Colorado School of Medicine. He and a team discovered that, while alcohol use is a risk factor for head and neck cancer, the chemical resveratrol found in grape skins and in red wine may prevent cancer as well.
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.
This week’s Scientist of the Week is Susanne Renner from Ludwig Maximilians Universität München. She and a team discovered that botanists made a mistake, over 80 years ago, when they concluded that edible watermelon came from South Africa.
This week’s Scientist of the Week is Paul Talalay of Johns Hopkins School of Medicine. He and a team performed a clinical trial on 40 boys and men between the ages of 13 and 27. Their results suggest that a chemical derived from broccoli sprouts may ease classic behavioral symptoms in those with autism spectrum disorders.
Diego Garcia-Bellido and a team from the Univ. of Adelaide found fossils that were confirmed as distant cousins to humans.
The National Medal of Science, created by Congress in 1959, is the country’s highest honor for achievement and leadership in advancing the fields of science and technology. A 12-member presidential committee, presented by the National Science Foundation, selects the award recipients. Recently announced by President Obama, the editors catch up with 2014 National Medal of Science winners to get their thoughts on the award.
Jocelyn Dunn, an industrial engineering doctoral student at Purdue Univ., is a part of a project to live on a landscape mimicking Mars for eight months. Along with five other researchers, she will be living in a domed habitat emulating what settlers might have on Mars. While exploring the environment, they will wear spacesuits and their communications will be delayed by 20 minutes to emulate the drag they would experience on the Red Planet.
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.
The Turkana Basin, which stretches from northern Kenya to southern Ethiopia, is one of the most continuous fossil records of the Plio-Pleistocene, with some fossils as old as the Cretaceous period. This August and September, the treasure trove of prehistoric records was studied by paleontologist Louise Leakey, the granddaughter of the famous Louis and Mary Leakey.
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.
