Liquid Spacetime - The Fluid Flow Of General Relativity?

General - 1 hour 42 min ago

Quantum mechanics is able to effectively explain three of the four fundamental forces of the Universe - electromagnetism, weak interaction and strong interaction - but it does not explain gravity, which is currently only accounted for by general relativity, which is classical physics.

Identifying a plausible model of quantum gravity - a description of gravity within a quantum physics framework - is one of the major challenges physics is facing today. Despite many, many, many hypothetical models proposed to date, none has proved satisfactory or, more importantly, amenable to empirical investigation.

What Do You Do With 1 Million Feral Camels?

Science2.0 - 1 hour 52 min ago

Feral camels in the Australian outback are reviled as pests. Yet they thrive, totaling some one million strong.

How did they go from historic helper to overbearing invader? As usual, numbers make the difference. 

The deserts of the Australian outback are a notoriously inhospitable environment where few species can survive - but camels can. The dromedary camel (Camelus dromedarius) prospers where others perish, eating 80% of native plant species and obtaining much of their water through ingesting this vegetation.

Controlling Your Kids: Cut Up Their Food And They'll Calm Down

Science2.0 - 2 hours 45 min ago

Modern Western parents spend a lot of time trying to figure out new ways for kids not to be kids and to force their behavior into narrow ranges. Then modern Western spend a lot of time filling out surveys saying they want their kids to be intelligent, creative and independent. 

If you are a parent who wants to mollify the animalistic eating behavior of your child, don't give them a chicken drumstick, cut their food into little pieces for them. Yes, whole foods are causing bad behavior, according to a new paper.

There Are Two Reasons You Got Unfriended On Facebook

Science2.0 - 3 hours 49 min ago

20 years ago, your parents knew there were two things you did not discuss with dinner guests. Your grandparents knew it, your great-grandparents knew it. 2,000 years ago people knew it.

In 2014, we are so much smarter we no longer know it.

Maybe some surveys will help. And so to help us out, two papers address the most pressing topic in popular culture -  how people feel about being un-friended on Facebook. Ironically, they found this out by surveying people on Twitter.

High School Athletes: 2.5 Million Basketball Injuries In 6 Seasons

Science2.0 - 9 hours 20 min ago

Basketball is a popular high school sport in the United States with 1 million participants annually. A recently published study by researchers in the Center for Injury Research and Policy at Nationwide Children's Hospital is the first to compare and describe the occurrence and distribution patterns of basketball-related injuries treated in emergency departments and the high school athletic training setting among adolescents and teens.

Neuroscientists Discover Brain Circuits Involved In Emotion

Science2.0 - April 23, 2014 - 3:42am

Neuroscientists have discovered a brain pathway that underlies the emotional behaviours critical for survival.

New research by the University of Bristol, published in the Journal of Physiology today [23 April], has identified a chain of neural connections which links central survival circuits to the spinal cord, causing the body to freeze when experiencing fear.

Understanding how these central neural pathways work is a fundamental step towards developing effective treatments for emotional disorders such as anxiety, panic attacks and phobias.

Cougars' Diverse Diet Helped Them Survive The Pleistocene Mass Extinction

Science2.0 - April 23, 2014 - 3:41am

Cougars may have survived the mass extinction that took place about 12,000 years ago because they were not particular about what they ate, unlike their more finicky cousins--the saber-tooth cat and American lion. Both perished along with the woolly mammoth and many of the other supersized mammals that walked the Earth during the late Pleistocene.

That is the conclusion of a new analysis of the microscopic wear marks on the teeth of cougars, saber-tooth cats and American lions described in the April 23 issue of the journal Biology Letters.

Mantis Shrimp: Cool Eyes, And Stronger Than Airplanes

Science2.0 - April 22, 2014 - 11:58pm

Inspired by the fist-like club of a mantis shrimp, researchers have developed a design structure for composite materials that is more impact resistant and tougher than the standard used in airplanes.

The peacock mantis shrimp, or stomatopod, is a 4- to 6-inch-long rainbow-colored crustacean with a fist-like club that accelerates underwater faster than a 22-caliber bullet. Researchers, led by Kisailus, an associate professor of chemical engineering, are interested in the club because it can strike prey thousands of times without breaking.
