Origin Of High Energy Emission From Crab Nebula Identified
Another piece of the jigsaw in understanding how neutron stars work has been put in place following the discovery by scientists of the origin of the high energy emission from rotation-powered pulsars.

Cystic Fibrosis: Engineered Proteins Can 'Bypass' Genetic Defect
By manipulating the machinery used by our cells for quality control, researchers have found a way to restore the function of cystic fibrosis (CF) airway cells. This could significantly reduce the sticky mucus that plugs the lungs of CF patients, which leads to antibiotic-resistant infections and untimely death.

Quantum 'Traffic Jam' Revealed: Findings May Help Get Current Flowing At Higher Temperatures
Scientists at Brookhaven National Laboratory and collaborators have uncovered the first experimental evidence for why the transition temperature of high-temperature superconductors cannot simply be elevated by increasing the electrons' binding energy. The research demonstrates how, as electron-pair binding energy increases, the electrons' tendency to get caught in a quantum mechanical "traffic jam" overwhelms the interactions needed for the material to act as a superconductor -- a freely flowing fluid of electron pairs.

Common Treatment To Delay Labor Decreases Pre-term Infants' Risk For Cerebral Palsy
Pre-term infants born to mothers receiving intravenous magnesium sulfate -- a common treatment to delay labor -- are less likely to develop cerebral palsy than are pre-term infants whose mothers do not receive it, report researchers in a large National Institutes of Health research network.

Robots Learn To Predict Where Their Leader Is Going, And Follow Along
Researchers have come up with a control system that allows a robot to pick up on cues that the leader is about to turn, predict where it is going and follow it.

Risk Of Repeat Attacks In Heart Patients Causes Concern For Doctors
The risk of heart attack patients having repeat attacks after they are discharged from hospital is being underestimated, research has shown. An international study raises concerns that some patients may not be receiving the optimum medical treatment and follow-up care because doctors are misjudging the risk of a further heart attack.

Eyes Evolved For 'X-Ray Vision': Forward-facing Eyes Allow Animals To 'See Through' Clutter In The World
The advantage of using two eyes to see the world around us has long been associated solely with our capacity to see in 3-D. Now, a new study has uncovered a truly eye-opening advantage to binocular vision: our ability to see through things.

Variant Of Mad Cow Disease May Be Transmitted By Blood Transfusions, According To Animal Study
Blood transfusions are a valuable treatment mechanism in modern medicine, but can come with the risk of donor disease transmission. Researchers are continually studying the biology of blood products to understand how certain diseases are transmitted in an effort to reduce this risk during blood transfusions.

Not All Fat Is Created Equal: Fat In Obese Patients Is 'Sick' Compared To Fat From Lean Patients
A new study finds that fat in obese patients is "sick" when compared to fat from lean patients, which could more fully explain the link between obesity and higher risk of diabetes, heart disease and stroke.

Pregnancy Situations Have Impact On Brain Development In Pre-term Infants
Brain development in infants who are born very prematurely is still incomplete. Factors that cause premature birth may have an impact on the development of the premature infant's brain both during pregnancy and later on after birth.

Natural Chemical From Sea Sponges Induces Death In Cancer Cells Via Unusual Pathway
A chemical called candidaspongiolide (CAN) inhibits protein synthesis but also kills cancer cells by triggering caspase 12-dependent programmed cell death, according to an article in the Aug. 26 online issue of the Journal of the National Cancer Institute.

New Evidence On Addiction To Medicines: Diazepam Has Effect On Nerve Cells In The Brain Reward System
Addictions to medicines and drugs are thought to develop over a relatively long period of time. The process involves both structural and functional changes in brain nerve cells that are still poorly understood. However, a single drug or alcohol dose is sufficient to generate an initial stage of addiction.

Explosives Go 'Green' ... And Get More Precise
Certain explosives may soon get a little greener and a little more precise. Researchers have added unique green solvents (ionic liquids) to an explosive called TATB (1,3,5-triamino-2,4,6-trinitrobenzene) and improved the crystal quality and chemical purity of the material.

Class Of Diabetes Drugs Carries Significant Cardiovascular Risks
A class of oral drugs used to treat type 2 diabetes may make heart failure worse, according to an editorial published online in the journal Heart.

Even Without Dementia, Mental Skills Decline Years Before Death
A new study shows that older people's mental skills start declining years before death, even if they don't have dementia.

Recent Advances Make Cervical Cancer Control In Developing World Feasible For First Time
Recent advances in cervical cancer prevention mean that controlling the disease in developing countries is becoming feasible for the first time, experts say. Developments such as highly effective vaccines against the human papilloma virus (HPV) and promising new screening tests provide an unprecedented opportunity to tackle the disease in poor countries, where pap smear screening has largely failed because it is too expensive and too complicated to implement.

Ultra-energy Efficient Dryer Under Development
A total drying solution for the manufacturing industry which will make significant energy savings is currently under development.

Researchers To Survey Students On Managing Psychiatric Medications In The Transition From Home To College
An increasing number of students are packing more than their computers and iPods when leaving for college. They are bringing along prescribed psychiatric medications. Researchers at Case Western Reserve University will survey students on managing psychiatric medications in the transition from home to college.
-
Researchers Provide Solution To World?s Worst Mass Poisoning Case
A solution to the world's worst case of ongoing mass poisoning, linked to rising cancer rates in Southern Asia, has been developed by researchers from Queen's University Belfast. They have created new low-cost technology to provide arsenic-free water to millions of people in South Asia currently exposed to high levels of the poison in groundwater.
-
Potential New Targets For Antidepressant Medications
The news about antidepressant medications over the past several years has been mixed. The bad news from large multicenter studies such as STAR*D is that current antidepressant medications are effective, but not as effective as one might hope.
