Spacetime ripples from dying black holes could help reveal how they formed
2012-09-17
Researchers from Cardiff University have discovered a new property of black holes: their dying tones could reveal the cosmic crash that produced them.
Black holes are regions of space where gravity is so strong that not even light can escape and so isolated black holes are truly dark objects and don't emit any form of radiation.
However, black holes that get deformed, because of other black holes or stars crashing into them, are known to emit a new sort of radiation, called gravitational waves, which Einstein predicted nearly a hundred years ago.
Gravitational waves ...

Proof of added benefit of apixaban in hip replacement
2012-09-17
The clot-inhibiting drug apixaban (trade name: Eliquis®) was approved in May 2011 for the prevention of thrombosis (blood clots) after operations to replace a hip or knee joint. In an early benefit assessment pursuant to the "Act on the Reform of the Market for Medicinal Products" (AMNOG), the German Institute for Quality and Efficiency in Health Care (IQWiG) examined the added benefit of apixaban.
IQWiG found proof of minor added benefit for adult patients who had undergone hip replacement: symptomatic clots in the deep veins of the leg occurred less frequently with ...
Behavior issues are a bigger headache for children with migraines
2012-09-17
Los Angeles, (17 September 2012). Kids who get migraine headaches are much more likely than other children to also have behavioral difficulties, including social and attention issues, and anxiety and depression. The more frequent the headaches, the greater the effect, according to research out now in the journal Cephalagia, published by SAGE.
Marco Arruda, director of the Glia Institute in São Paulo, Brazil, together with Marcelo Bigal of the Albert Einstein College of Medicine in New York studied 1,856 Brazilian children aged 5 to 11. The authors say that this is the ...
Considerably more patients may benefit from effective antidiabetic drug
2012-09-17
The antidiabetic drug metformin is not prescribed for patients with reduced kidney function because the risk of adverse effects has been regarded as unacceptably high. A study at Sahlgrenska Academy, University of Gothenburg, Sweden, has found that the risks have been substantially overrated. As a result, many more patients with diabetes may be able to enjoy the benefits of the medication.
Type 2 diabetes, a very common condition, is increasingly prevalent around the world. Keeping diabetes under control and preventing complications requires not only lifestyle changes, ...
Eating well during pregnancy reduces baby's obesity risk regardless of mom's size
2012-09-17
Bethesda, MD — If you are overweight and pregnant, your baby isn't destined to a life of obesity after all, according to a new research report published online in The FASEB Journal. In the report, a team of U.S. scientists show that modifying fat intake during pregnancy to a moderate level is enough to benefit the child regardless of the mother's size. Specifically, they found that a protein called "SIRT1" rewrites a developing fetus' histone code, which affects his or her "epigenetic likelihood" of being overweight or obese throughout his or her lifetime.
"We are finding ...
Only children are significantly more likely to be overweight
2012-09-17
Children who grow up without siblings have a more than 50 percent higher risk of being overweight or obese than children with siblings. This is the finding of a study of 12,700 children in eight European countries, including Sweden, published in Nutrition and Diabetes. The University of Gothenburg, Sweden, was one of the participating universities in the study.
The study was conducted under the framework of the European research project Identification and prevention of Dietary and lifestyle-induced health EFfects In Children and infantS (IDEFICS), where researchers from ...

Assessing a new technique for ensuring fresh produce remains Salmonella-free
2012-09-17
Researchers at the Institute of Food Research have tested a new technique to ensure fresh produce is free of bacterial contamination.
Plasmas are a mix of highly energetic particles created when gases are excited by an energy source. They can be used to destroy bacteria but as new research shows, some can hide from its effects in the microscopic surface structures of different foods.
Eating fresh fruit and vegetables is promoted as part of a healthy lifestyle, and consumers are responding to this by eating more and in a greater variety. Ensuring fruit and vegetables ...
Simple test to predict if pregnant women will give birth prematurely
2012-09-17
Babies born early run a greater risk of serious complications. The researchers at the Sahlgrenska Academy, University of Gothenburg, Sweden, have now developed a method to predict if pregnant women with preterm contractions will give birth within seven days. The method offers new possibilities to delay delivery and prepare care for the premature baby.
Delivery before 37 full weeks, so-called preterm delivery, is the biggest problem in perinatal medicine today, as it increases the risk of the child being seriously ill in the short and long term. The problem is that only ...
Sound level around seriously ill patients 'like a busy road'
2012-09-17
Seriously ill patients in intensive care units are being cared for in environments with sound levels more than 20 dB higher than the WHO's recommendations. This is shown by a study carried out in partnership between the University of Gothenburg and the University of Borås.
In the study, the researchers registered sound levels around 13 seriously ill patients cared for in the intensive care unit at Södra Älvsborg Hospital over a 24-hour period. The study shows that the sound levels around seriously ill patients were on average between 51 and 55 dB. This is comparable ...

US underestimates costs of carbon pollution and climate change
2012-09-17
The U.S. federal government is significantly underestimating the costs of carbon pollution because it is using a faulty analytical model, according to a new study published in the Journal of Environmental Studies and Sciences.
A more appropriate accounting of costs would pave the way to cleaner, more economically efficient sources of power generation, the study found.
"This is a wake-up call for America to start aggressively investing in low carbon sources of energy. The very real economic benefits will accrue quickly and increase over time," said Dr. Laurie Johnson, ...
Researchers call for early diagnosis of flesh-eating infections
2012-09-17
New Orleans, LA – Dr. Russell Russo, an Orthopedic Surgeon at LSU Health Sciences Center New Orleans, and other researchers stress that orthopedists should have a high index of suspicion for necrotizing fasciitis, or flesh-eating bacterial infection, in every patient with pain or other symptoms that are out of proportion to the initial diagnosis. Their recommendations are published in the September 2012 issue of Orthopedics Today.
Although relatively rare and difficult to diagnose because its symptoms often resemble other conditions like synovitis or cellutitis, a missed ...
When it rains, it pours
2012-09-17
CAMBRIDGE, Mass. — Extreme precipitation in the tropics comes in many forms: thunderstorm complexes, flood-inducing monsoons and wide-sweeping cyclones like the recent Hurricane Isaac.
Global warming is expected to intensify extreme precipitation, but the rate at which it does so in the tropics has remained unclear. Now an MIT study has given an estimate based on model simulations and observations: With every 1 degree Celsius rise in temperature, the study finds, tropical regions will see 10 percent heavier rainfall extremes, with possible impacts for flooding in populous ...
Majority of US Schools not ready for next pandemic, SLU researchers say
2012-09-17
ST. LOUIS – Many U.S. schools are not prepared for bioterrorism attacks, outbreaks of emerging infectious diseases or pandemics, despite the recent 2009 H1N1 influenza pandemic that resulted in more than 18,000 deaths worldwide, Saint Louis University researchers say.
The study, led by Terri Rebmann, Ph.D., associate professor at SLU's Institute for Biosecurity, surveyed about 2000 nurses working in elementary, middle and high schools across 26 states. The findings reveal that only 48 percent of schools address pandemic preparedness and only 40 percent of schools have ...

Dry-run experiments verify key aspect of Sandia nuclear fusion concept
2012-09-17
ALBUQUERQUE, N.M. — Magnetically imploded tubes called liners, intended to help produce controlled nuclear fusion at scientific "break-even" energies or better within the next few years, have functioned successfully in preliminary tests, according to a Sandia research paper accepted for publication by Physical Review Letters (PRL).
To exceed scientific break-even is the most hotly sought-after goal of fusion research, in which the energy released by a fusion reaction is greater than the energy put into it — an achievement that would have extraordinary energy and defense ...
Further steps needed to reduce stigma and expand access to substance abuse
2012-09-17
WASHINGTON — Outdated approaches to preventing and treating substance abuse, barriers to care, and other problems hinder the U.S. Defense Department's ability to curb substance use disorders among military service members and their families, says a new report from the Institute of Medicine. Service members' rising rate of prescription drug addiction and their difficulty in accessing adequate treatment for alcohol and drug-related disorders were among the concerns that prompted members of Congress to request this review.
"We commend the steps that the Department of Defense ...
Berkeley Lab sensors enable first light for the dark energy camera
2012-09-17
Early in the morning of September 12 the Dark Energy Camera (DECam), mounted on the Victor Blanco Telescope at the Cerro Tololo Inter-American Observatory in Chile, recorded its first images of a southern sky spangled with galaxies. Galaxies up to eight billion light years away were captured on DECam's focal plane, whose imager consists of 62 charge-coupled devices (CCDs) invented and developed by engineers and physicists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab).
Berkeley Lab CCDs are noted for their exceptionally high ...
World's most powerful digital camera opens eye, records first images in hunt for dark energy
2012-09-17
Eight billion years ago, rays of light from distant galaxies began their long journey to Earth. That ancient starlight has now found its way to a mountaintop in Chile, where the newly constructed Dark Energy Camera, the most powerful sky-mapping machine ever created, has captured and recorded it for the first time.
That light may hold within it the answer to one of the biggest mysteries in physics – why the expansion of the universe is speeding up.
Scientists in the international Dark Energy Survey collaboration announced this week that the Dark Energy Camera, the ...
Improving memory for specific events can alleviate symptoms of depression
2012-09-17
Hear the word "party" and memories of your 8th birthday sleepover or the big bash you attended last New Year's may come rushing to mind. But it's exactly these kinds of memories, embedded in a specific place and time, that people with depression have difficulty recalling.
Research has shown that people who suffer from, or are at risk of, depression have difficulty tapping into specific memories from their own past, an impairment that affects their ability to solve problems and leads them to focus on feelings of distress.
In a study forthcoming in Clinical Psychological ...

Flu antibody’s 'one-handed grab' may boost effort toward universal vaccine, new therapies
2012-09-17
LA JOLLA, CA -- Scientists from The Scripps Research Institute and Sea Lane Biotechnologies have solved the co-crystal structure of a human antibody that can neutralize influenza viruses in a unique way. The antibody recognizes the crucial structure that flu viruses use to attach to host cells, even though previously this structure had been thought too small for an antibody to grab effectively. The immune protein manages to hit this precise spot by using just a small part of its target-grabbing apparatus. In so doing, it can neutralize a broad range of dangerous flu viruses.
