Therapeutic Venoms Catalogued in New Database

November 25, 2015 2:34 pm | by Seth Augenstein, Digital Reporter | Comments

Nature’s chemical warfare can also be a medicinal trove, with potentially many more discoveries out there in the fangs, stingers and darts in the weapons of the wild. Now a team has put together a database to centralize the research on the relatively-untapped natural resources.


Exposure to Nature Linked to Safer Communities

November 25, 2015 2:19 pm | by American Institute of Biological Sciences | Comments

Numerous studies have demonstrated the benefits of contact with nature for human well-being. However, despite strong trends toward greater urbanization and declining green space, little is known about the social consequences of such contact.


Great Barrier Reef Protecting Against Landslides, Tsunamis

November 25, 2015 2:13 pm | by University of Sydney | Comments

The world-famous Australian reef is providing an effective barrier against landslide-induced tsunamis, new research shows. What has developed into the Great Barrier Reef was not always a barrier reef - it was once a fringing reef and did not offer the same protective quality.


New Foam Made of Gold is 'Light as Air'

November 25, 2015 2:07 pm | by ETH Zurich | Comments

A nugget of real 20 carats gold, so light that it does not sink in a cappuccino, floating instead on the milk foam – what sounds unbelievable has actually been accomplished by researchers. Scientists have produced a new kind of foam out of gold, a three-dimensional mesh of gold that consists mostly of pores. It is the lightest gold nugget ever created.


Anthropologist Explains Evolution of Thanksgiving

November 25, 2015 1:54 pm | by Boston University | Comments

No one truly knows what was served at that first Thanksgiving dinner, but most Americans are familiar with what fills the plate today. Turkey, stuffing, mashed potatoes, cranberry sauce and pumpkin pie are staples on nearly everyone’s menu — which prompts the question: why?


Researchers Discover New Way to Make X-rays

November 25, 2015 12:10 pm | by MIT | Comments

The most widely used technology for producing X-rays – used in everything from medical and dental imaging, to testing for cracks in industrial materials – has remained essentially the same for more than a century. But based on a new analysis by researchers, that might potentially change in the next few years.


Gut Bacteria Control When, How We Eat

November 25, 2015 12:02 pm | by Cell Press | Comments

Don't have room for dessert? The bacteria in your gut may be telling you something. Twenty minutes after a meal, gut microbes produce proteins that can suppress food intake in animals, reports a new study.


Internal Bone-lengthening Device Invented

November 25, 2015 9:43 am | by Texas Tech University Health Sciences Center El Paso | Comments

An orthopedic surgeon is creating the world’s first implantation device that can lengthen the bones of young children internally. The inventor expects the device will lead to fewer infections and less pain, making the bone-lengthening process more bearable for children.


Biologists Induce Flatworms to Grow Heads, Brains of Other Species

November 25, 2015 9:39 am | by Tufts University | Comments

Biologists have succeeded in inducing one species of flatworm to grow heads and brains characteristic of another species of flatworm without altering genomic sequence. The work reveals physiological circuits as a new kind of epigenetics – information existing outside of genomic sequence – that determines large-scale anatomy.


Coca-Cola’s Top Scientist Steps Down in Wake of Obesity Research Controversy

November 25, 2015 9:29 am | by Seth Augenstein, Digital Reporter | Comments

The top scientist at Coca-Cola, who helped plan and organize the anti-obesity campaign which touted “energy balance” instead of calorie reduction, has left the company, according to a new report. Rhona Applebaum is leaving the company, after serving as Coke’s chief scientific and regulatory officer since 2004.


Physical Activity Linked to Memory Skills

November 25, 2015 9:20 am | by Boston University Medical Center | Comments

Could staying physically active improve quality of life by delaying cognitive decline and prolonging an independent lifestyle? A new study has found that older adults who take more steps either by walking or jogging perform better on memory tasks than those who are more sedentary.


Betrayals of Trust Caused Rapid Spread of Human Species Worldwide

November 25, 2015 9:16 am | by University of York | Comments

New research by an archaeologist suggests that betrayals of trust were the missing link in understanding the rapid spread of our own species around the world. The speed and character of human dispersals changed significantly around 100,000 years ago.


Temperate Forests' Carbon Content Overestimated

November 25, 2015 9:03 am | by NASA/Goddard Space Flight Center | Comments

Digital measurements of millions of trees indicate that previous studies likely overestimate the amount of carbon stored by temperate U.S. forests, according to a new study. The findings could help scientists better understand the impact that trees have on the amount of carbon in the atmosphere.


Secrets of Penguin Feathers Lead to New De-icing Methods

November 24, 2015 3:29 pm | by Lauren Scrudato, Associate Editor | Comments

Airline travelers may soon be able to thank the biology of penguins for eliminating flight delays due to aircraft icing. Researchers examined donated feathers under a scanning electron microscope to determine how penguins are able to remain ice-free despite traveling between frigid water and icy terrain.


Reusable Rocket: In a First, Booster Returns Safely to Earth

November 24, 2015 2:42 pm | by Associated Press, Malcom Ritter | Comments

A private space company announced Tuesday that it had landed a rocket upright and gently enough to be used again, a milestone in commercial aeronautics. Reusing rockets, rather than discarding them, would be a big step toward making space flight less expensive.
