No evidence of the double nature of neutrinos

Posted: 04 Jun 2014 10:38 AM PDT

After two years of searching for a special radioactive decay that would provide an indication of new physics beyond the standard model, an experiment deep under ground near Carlsbad has so far found no evidence of its existence. If this decay indeed exists, its half-life must be more than a million-billion times longer than the age of the universe.

Surprisingly strong magnetic fields can match black holes' pull: Long-neglected magnetic fields have an unexpected presence

Posted: 04 Jun 2014 10:38 AM PDT

A new study of supermassive black holes at the centers of galaxies has found magnetic fields play an impressive role in the systems' dynamics. In fact, in dozens of black holes surveyed, the magnetic field strength matched the force produced by the black holes' powerful gravitational pull.

Hemorrhagic Fevers Can Be Caused by Body's Antiviral Interferon Response

Posted: 04 Jun 2014 10:37 AM PDT

Virologists and immunologists have found a major clue to the mystery of "hemorrhagic fever" syndromes. The team showed that Interferon Type I immune proteins are key drivers of a viral syndrome in mice that closely mimics human hemorrhagic fevers. Hemorrhagic fevers caused by Lassa, dengue and other viruses affect more than one million people annually and are often fatal, yet scientists, until now, have never understood why only some virus-infected people come down with the disease and others do not.

Early palliative support services help those caring for patients with advanced cancer

Posted: 04 Jun 2014 10:37 AM PDT

Those caring for patients with advanced cancer experienced reduced depression and felt less burdened by caregiving tasks when palliative support services were offered soon after the patient's diagnosis. "Family caregivers are a crucial part of the patient care team. Because the well-being of one affects the well-being of the other, both parties benefit when caregivers receive palliative care," said the senior study author.

Discovery of compound may open new road to diabetes treatment

Posted: 04 Jun 2014 10:37 AM PDT

The discovery of an inhibitor of the Insulin Degrading Enzyme (IDE), a protein responsible for the susceptibility of diabetes because it destroys insulin in the body, may lead to new treatment approaches for diabetes, researchers say. More than 20 million people live with type II diabetes in the United States, a disease in which the body cannot make sufficient amounts of the hormone insulin.

Results indicate that nearly half of respondents had both a navigation and survivorship program at their institution. Full-time navigators had an average patient load of 100-400 patients, in various phases of the cancer continuum of screening, diagnosis, treatment, and posttreatment.

Courts face challenges when linking genetics to criminal behavior

Posted: 04 Jun 2014 09:35 AM PDT

Some people may be at increased risk of criminal behavior due to their genes, some say. Such research holds potential for helping judges and juries with some of the difficult decisions they must make, but it also brings a substantial risk of misinterpretation and misuse within the legal system. Experts suggest that addressing these issues will be of critical importance for upholding principles of justice and fairness.

How red tide knocks out its competition

Posted: 04 Jun 2014 09:34 AM PDT

New research reveals how the algae behind red tide thoroughly disables – but doesn't kill – other species of algae. The study shows how chemical signaling between algae can trigger big changes in the marine ecosystem. The algae that form red tide in the Gulf of Mexico are dinoflagellates called Karenia brevis, or just Karenia by scientists. Karenia makes neurotoxins that are toxic to humans and fish. Karenia also makes small molecules that are toxic to other marine algae, which is what the new study analyzed.

Astronomers discover first Thorne-Zytkow object, a bizarre type of hybrid star

Posted: 04 Jun 2014 08:51 AM PDT

In a discovery decades in the making, scientists have detected the first of a 'theoretical' class of stars first proposed in 1975 by physicist Kip Thorne and astronomer Anna Zytkow. Thorne-Zytkow objects are hybrids of red supergiant and neutron stars that superficially resemble normal red supergiants, such as Betelguese in the constellation Orion. They differ, however, in their distinct chemical signatures that result from unique activity in their stellar interiors.

NASA should maintain long-term focus on Mars as 'horizon goal' for human spaceflight

Posted: 04 Jun 2014 08:51 AM PDT

Arguing for a continuation of the nation's human space exploration program, a new congressionally mandated report from the National Research Council concludes that the expense of human spaceflight and the dangers to the astronauts involved can be justified only by the goal of putting humans on other worlds.

New approach to diversity research proposed by professor

Posted: 04 Jun 2014 08:51 AM PDT

A rethinking of homogeneity as the baseline used to study diversity has been proposed by one expert in the field. Researchers have often used homogeneous social groups as a "baseline" to see what effects social diversity can have -- in the workplace, organizations, schools, and even markets. And yet, he contends, there are good reasons to think that such an approach fails to fully capture the social dynamics in play. "Both diversity and homogeneity have the ability to affect how people think or make decisions," he notes.

Doctors reluctant to discuss end-of-life care with heart failure patients

Posted: 04 Jun 2014 08:51 AM PDT

Few healthcare providers report talking to their heart failure patients about end-of-life care preferences. Doctors, nurse practitioners and physician assistants cited patient uneasiness, their own discomfort and lack of time as main reasons for not discussing the subject. Nearly a third of clinicians surveyed said they lacked the confidence to bring up the subject of end-of-life care.

Heart disease without coronary plaque buildup linked to heart attack risk

Posted: 04 Jun 2014 07:54 AM PDT

Non-obstructive coronary artery disease was associated with a 28 to 44 percent increased risk of a major adverse cardiac event such as a heart attack or death. The possible cause is that the non-obstructive plaques can still rupture and cause heart attacks. Providers and patients should take note of non-obstructive CAD and consider lifestyle changes and medications that could help prevent it from causing future adverse cardiac events such as heart attacks.

Crows' memories are made of this: Scientists discover neurons allowing crows to remember short-term

Posted: 04 Jun 2014 07:53 AM PDT

Researchers have discovered neurons allowing crows to remember short-term, although their brains are different from ours. An important prerequisite for intelligence is a good short-term memory which can store and process the information needed for ongoing processes. This "working memory" is a kind of mental notepad -- without it, we could not follow a conversation, do mental arithmetic, or play any simple game.

Small-molecule drugs moved through blood-brain barrier in new study

Posted: 04 Jun 2014 07:53 AM PDT

A recently developed synthetic peptide carrier is a potential delivery vehicle for brain cancer chemotherapy drugs and other neurological medications, researchers have demonstrated in a mouse model. The blood-brain barrier is meant to protect the brain from numerous undesirable chemicals circulating in the body, but it also obstructs access for treatment of brain tumors and other conditions. Too often the only recourse is invasive, which often limits a drug's effectiveness or causes irreversible damage to an already damaged brain.

Medieval manholes: plumbers led the way in utility maintenance

Posted: 04 Jun 2014 06:35 AM PDT

The story of the medieval plumbers who maintained a complex water supply system, which was centuries ahead of its time, has been revealed by a historian. A unique network of subterranean tunnels, partly dating back to the 14th century, still lies beneath the streets of Exeter, Devon. These once channeled fresh drinking-water from springs outside the town-walls to public fountains at the heart of the city. "People from all social backgrounds relied on the system to provide their drinking water, so it was vital to keep it running smoothly. The city retained a plumber to carry out regular maintenance," said the author.

E-cigarettes may help smokers quit, but research is insufficient

Posted: 04 Jun 2014 06:35 AM PDT

E-cigarettes are a potential smoking cessation aid and they may also be able to lower the risk of nicotine dependency in high-risk groups. The available scientific evidence, however, remains insufficient. According to an international survey e-cigarettes were used by younger people, those with higher incomes, and heavier smokers in particular. Among e-cigarette users, 85% reported that they used them to stop smoking.

How long is too long to wait for groundbreaking new aortic valve replacement surgery procedures?

Posted: 04 Jun 2014 06:33 AM PDT

Severe aortic stenosis (AS) has a grave prognosis with 25-50% of patients dying within a year once symptoms develop. Transcatheter aortic valve replacement (TAVR) represents a paradigm shift in the therapeutic options for these patients. Because of cost and availability issues, there are often waiting times for this procedure. Investigators have found that even modest increases in wait times have a substantial impact on the effectiveness of TAVR in individuals who need it the most: otherwise inoperable patients and high-risk surgical candidates. Creating benchmarks for appropriate wait times should be a priority, say investigators.

Posted: 04 Jun 2014 06:27 AM PDT

A person's genetic risk for obesity is linked with Body Mass Index (BMI), researchers show. They also explain that saturated fat intake may influence the expression of a person's genetic obesity risk. Limiting saturated fat could help people whose genetic make-up increases their chance of being obese.

Possible benefits of brain stimulation on hand, arm movement following stroke

Posted: 04 Jun 2014 06:27 AM PDT

Researchers are studying whether stimulating the brain before rehabilitation could yield greater gains in motor function for people recovering from stroke. The technology is akin to a more advanced version of constraint-induced therapy in which clinicians physically tie down a patient's good arm, which forces the patient to use the injured side. With this non-invasive device, researchers are using electromagnetism to slow activity in portions of the healthy brain hemisphere that control the uninjured arm, similarly forcing the brain to use its injured half.

Parasites fail to halt European bumblebee invasion of the UK

Posted: 03 Jun 2014 08:10 PM PDT

A species of bee from Europe that has stronger resistance to parasite infections than native bumblebees has spread across the UK, according to new research. The study shows that tree bumblebees have rapidly spread despite them carrying high levels of an infection that normally prevents queen bees from producing colonies. The species arrived in the UK from continental Europe 13 years ago and has successfully spread at an average rate of nearly 4,500 square miles -- about half the size of Wales -- every year.

Astronomers discover two new worlds orbiting ancient star next door: One may be warm enough to have liquid water

Posted: 03 Jun 2014 04:40 PM PDT

Astronomers have discovered two new planets orbiting a very old star that is near to our own sun. One of these planets orbits the star at the right distance to allow liquid water to exist on its surface, a key ingredient to support life. Kapteyn's Star, named after the Dutch astronomer, Jacobus Kapteyn, who discovered it at the end of the 19th century, is the second fastest-moving star in the sky and belongs to the Galactic halo, an extended group of stars orbiting our Galaxy on very elliptical orbits. With a third of the mass of the Sun, this red-dwarf can be seen with an amateur telescope in the southern constellation of Pictor.

Iron, steel in hatcheries may distort magnetic 'map sense' of steelhead

Posted: 03 Jun 2014 04:40 PM PDT

Exposure to iron pipes and steel rebar, such as the materials found in most hatcheries, affects the navigation ability of young steelhead trout by altering the important magnetic 'map sense' they need for migration.
