Some of the brightest galaxies in the universe – infant galaxies that churned out tens of thousands of stars each year at the dawn of the universe – evolved much sooner and in greater numbers than previously thought, according to new measurements obtained by University of Arizona astronomers. The results are published in a set of papers to appear in the journal Nature on March 14 and in the Astrophysical Journal. The research is the most recent example of the discoveries coming from the new international ALMA observatory, which celebrates its inauguration today. ALMA, ...

ORLANDO, Fla., March 13, 2013 – Researchers at Sanford-Burnham Medical Research Institute (Sanford-Burnham) have determined the complete three-dimensional structure of a protein called HNF-4α. HNF-4α controls gene expression in the liver and pancreas, switching genes on or off as needed. People with mature onset diabetes of the young (MODY1), a rare form of the disease, have inherited mutations in the HNF-4α protein. This first-ever look at HNF-4α's full structure, published March 13 in Nature, uncovers new information about how it functions. The study ...

NEW YORK, MARCH 13, 2013 – Researchers have discovered a unique monoclonal antibody that can effectively reach inside a cancer cell, a key goal for these important anticancer agents, since most proteins that cause cancer or are associated with cancer are buried inside cancer cells. Scientists from Memorial Sloan-Kettering Cancer Center and Eureka Therapeutics have collaborated to create the new human monoclonal antibody, which targets a protein associated with many types of cancer and is of great interest to cancer researchers. Unlike other human therapeutic monoclonal ...

When a batch of bright cosmic objects first appeared in maps in 2008 made with data from the South Pole Telescope, astronomers at the University of Chicago's Kavli Institute for Cosmological Physics regarded it only as an unavoidable nuisance. The light sources interfered with efforts to measure more precisely the cosmic microwave background—the afterglow of the big bang. But the astronomers soon realized that they had made a rare find in South Pole Telescope's large survey of the sky. The spectra of some of the bright objects, which is the rainbow of light they emit, ...

In the southern Rift Valley of Kenya, the Maasai people, their livestock and a range of carnivores, including striped hyenas, spotted hyenas, lions and bat-eared foxes, are coexisting fairly happily according to a team of coupled human and natural systems researchers. "I wouldn't call the results surprising," said Meredith Evans Wagner, a visiting scholar from the University of Florida in the Center for Systems Integration and Sustainability (CSIS) at Michigan State University and part of the research team. "Other research has shown that people and carnivores can coexist, ...

PASADENA, Calif.—Galaxies have been experiencing vigorous bursts of star formation from much earlier in cosmic history than previously thought, according to new observations by a Caltech-led team. These so-called starburst galaxies produce stars at a prodigious rate—creating the equivalent of a thousand new suns per year. Now the astronomers have found starbursts that were churning out stars when the universe was just a billion years old. Previously, astronomers didn't know whether galaxies could form stars at such high rates so early in time. The discovery enables ...

Colonoscopy is one of the most effective cancer screening procedures available. Colon cancer grows very slowly and can be treated if caught early through screening. But, perhaps because of this success, older Americans are undergoing screening colonoscopies despite recommendations against screening in adults aged 76 and older. A new study by researchers at the University of Texas Medical Branch at Galveston published online today in JAMA Internal Medicine shows that one out of four colonoscopies paid for by Medicare is potentially inappropriate under current screening ...

MADISON, Wis., March 13, 2013 – Even after researchers studying White Nose Syndrome (WNS) established that a fungus called Geomyces destructans is at the heart of the devastating disease, detecting it depended largely on finding dead or dying bats. This month, the journal Mycologia will publish research by a team of U.S. Forest Service scientists and partners identifying additional species of Geomyces and describing development of a highly sensitive DNA-based technique for early identification of Geomyces destructans on bats as well as in soils and on cave walls. "The ...

CHAMPAIGN, Ill. — A little-noticed provision of the Affordable Care Act requires all chain restaurants and retail food establishments with 20 or more locations to list calorie counts on their menus. But according to research co-written by a University of Illinois agricultural economist, numeric calorie labels might not be the most effective way to influence patrons to select "healthier" (often interpreted as lower-calorie) items. Brenna Ellison, a professor of agricultural and consumer economics, says placing a symbolic label in addition to the numeric calorie information ...

NASA's Tropical Rainfall Measuring Mission satellite, also known as TRMM, flew over Cyclone Sandra twice in one day and noticed a large decrease in rainfall intensity over a nine hour period. On March 11, 2013, NASA's TRMM satellite twice flew above weakening tropical cyclone Sandra as it was passing to the west of New Caledonia in the southern Pacific Ocean. TRMM's Precipitation Radar (PR) had a very good view of Sandra as it passed directly above the tropical cyclone on March 11 at 1312 UTC (9:12 a.m. EST). TRMM PR measured rainfall at the extreme rate of over 206 mm ...

ATHENS, Ohio (March 13, 2013)—Dwelling on negative events can increase levels of inflammation in the body, a new Ohio University study finds. Researchers discovered that when study participants were asked to ruminate on a stressful incident, their levels of C-reactive protein, a marker of tissue inflammation, rose. The study is the first time to directly measure this effect in the body. "Much of the past work has looked at this in non-experimental designs. Researchers have asked people to report their tendency to ruminate, and then looked to see if it connected to physiological ...

March 12, 2013 — Albuquerque, NM (UNM Cancer Center) — It's the spread of the original cancer tumor that kills most people. That's why cancer researchers vigorously search for drugs that can prevent metastases, the spread of cancer. The research team co-led by Angela Wandinger-Ness, PhD, and Larry Sklar, PhD, at the University of New Mexico Cancer Center has found a chemical compound that appears to control cell migration and adhesion, two important characteristics of metastatic cancer cells. The team recently published a paper describing how the first-in-class compound ...

The sun recently erupted with two coronal mass ejections (CMEs). One began at 8:36 p.m. EDT on March 12, 2013 and is directed toward three NASA spacecraft, Spitzer, Kepler and Epoxi. There is, however, no particle radiation associated with this event, which is what would normally concern operators of interplanetary spacecraft since the particles can trip computer electronics on board. A second CME began at 6:54 a.m. EDT on March 13, 2013 and its flank may pass by Earth at a speed that does not typically have a significant impact at Earth. Experimental NASA research models, ...

Boston – High blood pressure, a risk factor for heart attacks, heart failure and stroke, is 40 percent more common in African-Americans than in other American ethnic groups. In a new study from Brigham and Women's Hospital (BWH), along with the Dana-Farber Cancer Institute and Massachusetts General Hospital, researchers show that vitamin D supplementation may help African-Americans lower their blood pressure. The study publishes online in the March 13, 2013 edition of the American Heart Association journal Hypertension. "This study may explain and help treat an important ...

Higher mortality rates among Americans younger than 50 are responsible for much of why life expectancy is lower in the United States than most of the world's most developed nations. The research, by Jessica Ho, a University of Pennsylvania doctoral candidate in demography and sociology, found that excess mortality among Americans younger than 50 accounted for two-thirds of the gap in life expectancy at birth between American males and their counterparts and two-fifths between females and their counterparts in the comparison countries. The study, "Mortality Under Age ...

Life as we know it is based upon the elements of carbon and oxygen. Now a team of physicists, including one from North Carolina State University, is looking at the conditions necessary to the formation of those two elements in the universe. They've found that when it comes to supporting life, the universe leaves very little margin for error. Both carbon and oxygen are produced when helium burns inside of giant red stars. Carbon-12, an essential element we're all made of, can only form when three alpha particles, or helium-4 nuclei, combine in a very specific way. The ...

Heavy rains have become more frequent in the upper Midwest over the past 60 years, according to a study from the University of Iowa. The trend appears to hold true even with the current drought plaguing the region, the study's main author says. The fact that temperatures over the country's midsection are rising, too, may be more than coincidence.The hotter the surface temperature, which has been the trend in the Midwest and the rest of the world, the more water that can be absorbed by the atmosphere. And the more water available for precipitation means a greater chance ...

Playing video games for an hour each day can improve subsequent performance on cognitive tasks that use similar mental processes to those involved in the game, according to research published March 13 in the open access journal PLOS ONE by Adam Chie-Ming Oei and Michael Donald Patterson of Nanyang Technological University, Singapore. Non-gamer participants played five different games on their smartphones for an hour a day, five days of the week for one month. Each participant was assigned one game. Some played games like Bejeweled where participants matched three identical ...

WASHINGTON — While acupuncture is used widely to treat chronic stress, the mechanism of action leading to reported health benefits are not understood. In a series of studies at Georgetown University Medical Center (GUMC), researchers are demonstrating how acupuncture can significantly reduce the stress hormone response in an animal model of chronic stress. The latest study was published today in the April issue of Journal of Endocrinology. "Many practitioners of acupuncture have observed that this ancient practice can reduce stress in their patients, but there is a ...

A team of interventional neuroradiologists and neurosurgeons at Johns Hopkins reports wide success with a new procedure to treat pseudotumor cerebri, a rare but potentially blinding condition marked by excessive pressure inside the skull, caused by a dangerous narrowing of a vein located at the base of the brain. The Johns Hopkins team's latest study, to be published in the Journal of Neuro-Ophthalmology online March 14, is believed to be the first to show how directly lowering pressure inside the vein alleviates the condition and improves vision. The study report on ...

DETROIT – Difficulty or inability to write a coherent text message, even in patients who have no problem speaking, may become a "vital" tool in diagnosing a type of crippling stroke, according to new research at Henry Ford Hospital. The case study focused on a 40-year-old man visiting the metro Detroit area on business who showed signs of "dystextia," a recently coined term for incoherent text messaging that can sometimes be confused with autocorrect garble. But in his case, the man saw nothing wrong with the garble. The patient had no problem with a routine bedside ...

DETROIT – Rapid hearing loss in both ears may be a symptom of the rare but always-fatal Creutzfeldt-Jakob Disease and should be considered a reason for clinicians to test for the disorder. That was the conclusion of Henry Ford Hospital researchers after encountering a 67-year-old patient who had been progressively losing hearing in both ears for two months and was eventually diagnosed with the disease. Creutzfeldt-Jakob Disease, or CJD, is often confused with so-called "mad cow disease," and though they are in the same family of disorders, are not the same. However, ...

Three myths about sleepwalking – sleepwalkers have no memory of their actions, sleepwalkers' behaviour is without motivation, and sleepwalking has no daytime impact – are dispelled in a recent study led by Antonio Zadra of the University of Montreal and its affiliated Sacré-Coeur Hospital. Working from numerous studies over the last 15 years at the hospital's Centre for Advanced Studies in Sleep Medicine at the Hôpital du Sacré-Cœur de Montréal and a thorough analysis of the literature, Zadra and his colleagues have raised the veil on sleepwalking and clarified the diagnostic ...
