Getting a handle on chronic pain
Chronic pain has a significant impact on the physical, social and emotional functioning of those who suffer from it. It is also notoriously challenging to diagnose and treat, because pain is such a subjective experience. Scientists at EPFL (Ecole Polytechnique Federale de Lausanne) have developed a new tool that will give doctors an objective way to evaluate a patient's pain level. This in turn will enable them to tailor more targeted treatments and monitor their effectiveness over time.

Study shows cognitive behavioral therapy is a safe and effective treatment for women having hot flushes and night sweats following breast cancer treatment
Hot flushes and night sweats affect 65-85 percent of women after breast cancer treatment; they are distressing, causing sleep problems and decreased quality of life. Hormone replacement therapy is often either undesirable or contraindicated. A new study published online first by the Lancet Oncology shows that cognitive behavioral therapy is a safe and effective treatment for these women, with additional benefits to mood, sleep, and quality of life.

Switching antiepileptic drugs could increase risk of seizures

VLT takes most detailed infrared image of the Carina Nebula
ESO's Very Large Telescope has delivered the most detailed infrared image of the Carina Nebula stellar nursery taken so far. Many previously hidden features, scattered across a spectacular celestial landscape of gas, dust and young stars, have emerged. This is one of the most dramatic images ever created by the VLT.

Study posits a theory of moral behavior
Why do some people behave morally while others do not? Sociologists at the University of California, Riverside and California State University, Northridge have developed a theory of the moral self that may help explain the ethical lapses in the banking, investment and mortgage-lending industries that nearly ruined the US economy.

Study of Alzheimer's-related protein in healthy adults may shed light on earliest signs of disease
Researchers from the Center for Vital Longevity at The University of Texas at Dallas and UT Southwestern Medical Center have completed a large-scale neuroimaging study of healthy adults from age 30 to 90 that measured beta-amyloid protein -- a substance whose toxic buildup in the brain is a diagnostic marker for Alzheimer's disease. Their findings reveal that high levels of amyloid may have negative effects on cognitive function even in healthy adults.

A 2-pronged attack: Why loss of STAT1 is bad news
Breast cancer represents about a fifth of all cancers diagnosed in women. The reasons for the rapid progression of the disease remain relatively poorly understood but recent work in the group of Veronika Sexl at the University of Veterinary Medicine, Vienna has pointed the finger strongly at loss or inactivation of the transcription factor STAT1. The results are published in the current issue of the journal Oncotarget.

New super-Earth detected within the habitable zone of a nearby cool star
An international team of scientists led by Carnegie's Guillem Anglada-Escudé and Paul Butler has discovered a potentially habitable super-Earth orbiting a nearby star. The star is a member of a triple star system and has a different makeup than our Sun, being relatively lacking in metallic elements. This discovery demonstrates that habitable planets could form in a greater variety of environments than previously believed.

A small population of rattlesnakes that already is in decline in southern Illinois faces a new and unexpected threat in the form of a fungus rarely seen in the wild, researchers report. The finding matches reports of rattlesnake deaths in the northeast United States.

Discovery in Nature elucidates immune cells in skin and supports novel vaccine approach
Research in Nature shows for the first time in vivo that powerful immune system cells called TREMs (T-Resident Effector Memory cells) prevalent in the skin are more protective in fighting infection than central memory T-cells in the bloodstream. The study suggests vaccines to generate TREM can have optimal delivery to upper skin, for potentially more effective immune response than conventional vaccine injection. TREM Rx is translating this new insight into proprietary platform for novel vaccines.

CT colonography shown to be comparable to standard colonoscopy
Virtual colonoscopy is comparable to standard colonoscopy at detecting colorectal cancer and precancerous polyps in people ages 65 and older, according to a paper published online Feb. 23 in Radiology. This and results of a 2008 trial published in the New England Journal of Medicine, confirm the virtual exam can serve as a primary screening option. Medicare has refused coverage for the exam citing lack of data in patients ages 65 and older.

Pharmaceuticals from crab shells
The pharmaceutical NANA is 50 times more expensive than gold. Now it can be produced from chitin - a very cheap natural resource. The process was made possible by genetically modifying mold fungi.

Teen school drop-outs are almost three times as likely to be on benefits in later life as their peers who complete their schooling, indicates research published online in the Journal of Epidemiology and Community Health.

Potatoes lower blood pressure in people with obesity and hypertension without increasing weight
The first study to check the effects of eating potatoes on blood pressure in humans has concluded that two small helpings of purple potatoes a day decreases blood pressure by about four percent without causing weight gain. In a report in the ACS' Journal of Agricultural and Food Chemistry, the researchers say that decrease, although seemingly small, is sufficient to potentially reduce the risk of several forms of heart disease.

Assessing the value of BMI screening and surveillance in schools
An expert Roundtable Discussion in the current issue of Childhood Obesity, a peer-reviewed journal published by Mary Ann Liebert, Inc., debates the pros and cons of routine BMI screening in the school setting, discusses the most recent data, and explores when and for what purpose BMI screening results should be shared with parents and the potential benefits.

AAAS-SFU research: Linking human evolution and climate change
It's not a take on climate change we often hear about. But Mark Collard, a Simon Fraser University Canada Research Chair and professor of archaeology, will talk about how climate change impacts human evolution at the world's largest science fair. Collard will give a talk called Environmental drivers of technological evolution in small-scale populations during a seminar called Climate Change and Human Evolution: Problems and Prospects.

Study finds injectable treatment for blood clots in advanced cancer patients increases
The use of an injectable, clot-preventing drug known as Low Molecular Weight Heparin to treat patients with advanced cancer complicated by blood clots increased steadily between 2000 and 2007, according to a new study published in The Oncologist, funded by the National Cancer Institute and led by Kaiser Permanente Colorado. However, despite previous research indicating LMWH is the preferred first-line treatment for cancer patients experiencing blood clots, use of LMWH is low compared to another commonly used anticoagulant, warfarin.

Direct measurement of the formation length of photons
How long does it take an electron to form a photon? The answer would normally be: so short a time that it cannot be measured. However, the international CERN team responsible for experiment NA63 -- mainly staffed by physicists from Aarhus University -- has now succeeded in dragging out the process, thereby making it measurable.

Excess fat may be 'protective' in seniors over 85
Past the age of 85, says professor Jiska Cohen-Mansfield of Tel Aviv University, obese people were not only at lower risk of death than their underweight peers, but also appeared to be less at risk than those who had a normal weight as well. However, she warns that they may also suffer longer from obesity-related illnesses.
