UCLA psychologists have used brain-imaging techniques to study what happens to the human brain when it slips into unconsciousness. Their research, published Oct. 17 in the online journal PLOS Computational Biology, is an initial step toward developing a scientific definition of consciousness.

“In terms of brain function, the difference between being conscious and unconscious is a bit like the difference between driving from Los Angeles to New York in a straight line versus having to cover the same route hopping on and off several buses that force you to take a ‘zig-zag’ route and stop in several places,” said lead study author Martin Monti, an assistant professor of psychology and neurosurgery at UCLA.

UCLA physicists played prominent role in Nobel Prize-winning Higgs boson research

Two large collaborations of scientists working at the Large Hadron Collider in Switzerland made worldwide news in July 2012 when they announced independent observations of the elusive Higgs boson particle — a discovery hailed as one of the greatest scientific accomplishments of recent decades.

This so-called “God particle” was first postulated some 50 years ago as a crucial element of the modern theory of the forces of nature — it is, physicists say, what gives everything in the universe mass — and it had been the subject of worldwide searches ever since. (more…)

Facebook use predicts declines in happiness, new study finds

ANN ARBOR — Facebook helps people feel connected, but it doesn’t necessarily make them happier, a new study shows.   Facebook use actually predicts declines in a user’s well-being, according to a University of Michigan study that is the first known published research examining Facebook influence on happiness and satisfaction.

The study about the use of Facebook, a free networking website, appears online in PLOS ONE.

“On the surface, Facebook provides an invaluable resource for fulfilling the basic human need for social connection,” said U-M social psychologist Ethan Kross, lead author of the article and a faculty associate at the U-M Institute for Social Research. “But rather than enhance well-being, we found that Facebook use predicts the opposite result—it undermines it.” (more…)

Analysis of Greenland Ice Cores Adds to Historical Record and May Provide Glimpse into Climate’s Future

The International North Greenland Eemian Ice Drilling (NEEM) project results indicate that melting of Antarctic ice sheet may have contributed more to sea level rise than melting of the Greeland ice sheet some 100,000 years ago

A new study that provides surprising details on changes in Earth’s climate from more than 100,000 years ago indicates that the last interglacial–the period between “ice ages”–was warmer than previously thought and may be a good analog for future climate, as greenhouse gases increase in the atmosphere and global temperatures rise.

The research findings also indicate that melting of the massive West Antarctic ice sheet may have contributed more to sea-level rise at that time than melting of the Greenland ice sheet. (more…)

Medication Beliefs Strongly Affect Individuals’ Management of Chronic Diseases, MU Expert Says

Health practitioners should use behavior-change tactics so patients take medications as prescribed

COLUMBIA, Mo. – Nearly half of patients taking medications for chronic conditions do not strictly follow their prescribed medication regimens. Failure to use medications as directed increases patients’ risk for side effects, hospitalizations, reduced quality of life and shortened lifespans. Now, a University of Missouri gerontological nursing expert says patients’ poor adherence to prescribed medication regimens is connected to their beliefs about the necessity of prescriptions and concerns about long-term effects and dependency.

MU Assistant Professor Todd Ruppar found that patients’ beliefs about the causes of high blood pressure and the effectiveness of treatment alternatives significantly affected their likelihood of faithfully following prescribed medication regimens. In his pilot study, Ruppar focused on older patients’ adherence to medication treatments that control high blood pressure, a condition that affects nearly 70 million adults in the U.S. and can lead to heart disease and stroke.

Massive detector homes in on cosmic ray production

IceCube, an international collaboration involving University of Delaware scientists, is shedding new light on cosmic ray production.

Although cosmic rays were discovered 100 years ago, their origin remains one of the most enduring mysteries in physics. Now, the IceCube Neutrino Observatory, a massive detector in Antarctica, is homing in on how the highest energy cosmic rays are produced. (more…)

Ancient Domesticated Dog Skull Found in Siberian Cave

*A 33,000-year-old dog skull unearthed in a Siberian mountain cave presents some of the oldest known evidence of dog domestication and, together with an equally ancient find in a cave in Belgium, indicates that modern dogs may be descended from multiple ancestors.*

If you think a Chihuahua doesn’t have much in common with a Rottweiler, you might be on to something.

An ancient dog skull, preserved in a cave in the Altai Mountains of Siberia for 33,000 years, presents some of the oldest known evidence of dog domestication and, together with equally ancient dog remains from a cave in Belgium, indicates that domestication of dogs may have occurred repeatedly in different geographic locations rather than with a single domestication event.

The earliest known image of an Egyptian ruler wearing the “White Crown” associated with Egyptian dynastic power has been brought to light by an international team of archaeologists led by Egyptologists from Yale University.

Carved around 3200 BCE, this unique record of a royal celebration at the dawn of the Egyptian dynastic period was found at a site discovered almost a half-century ago by Egyptologist Labib Habachi at Nag el-Hamdulab, on the West Bank of the Nile to the north of Aswan. (more…)
