Sochi games influenced by Lake Placid winter Olympics of 1932

Posted: 18 Feb 2014 08:42 AM PST

Eight crashes that sent more than a dozen competitors to the hospital marred bobsled practice runs leading up to the 1932 winter Olympic games in Lake Placid, N.Y., but as dramatic as those incidents were, they also provide insight into more ordinary factors that continue to influence the Olympics, according to new research.

Frequent school moves can increase the risk of psychotic symptoms in early adolescence

Posted: 18 Feb 2014 08:05 AM PST

Researchers have shown that frequently changing schools during childhood can increase the risk of psychotic symptoms in later years. Scientists found that school mobility during childhood heightens the risk of developing psychotic-like symptoms in early adolescence by up to 60%. Suffering from psychotic-like symptoms at young age is strongly associated with mental health problems in adulthood, including psychotic disorders and suicide.

Beauty and bacteria: Slim, attractive men have less nasal bacteria than heavy men

Posted: 18 Feb 2014 07:07 AM PST

Do attractive traits tell us anything about a person's reproductive health? New research reveals a link between Body Mass Index (BMI) and the amount of bacteria colonizing noses. The results show that heavier men harbor more potentially pathogenic species of bacteria in their nose, compared with slimmer, more traditionally attractive men.

Extreme weather images in the media cause fear and disengagement with climate change

Posted: 18 Feb 2014 07:06 AM PST

Extreme weather images represent human suffering and loss. They are iconic of climate change and are symbols of its natural impacts. Reporting on extreme weather has increased over the last few years. In the past social scientists, and media and communication analysts have studied how climate change is depicted in the text of media and social media. While researchers have become increasingly interested in climate change images, they have not yet studied them with respect to symbolizing certain emotions.

Single chip device to provide real-time 3-D images from inside the heart, blood vessels

Posted: 18 Feb 2014 07:00 AM PST

Researchers have developed the technology for a catheter-based device that would provide forward-looking, real-time, three-dimensional imaging from inside the heart, coronary arteries and peripheral blood vessels.

It’s alive! Bacteria-filled liquid crystals could improve biosensing

Posted: 17 Feb 2014 05:07 PM PST

Plop living, swimming bacteria into a novel water-based, nontoxic liquid crystal and a new physics takes over. The dynamic interaction of the bacteria with the liquid crystal creates a novel form of soft matter: living liquid crystal. This new type of active material holds promise for improving the early detection of diseases.

Hormone released after exercise can 'predict' biological age

Posted: 17 Feb 2014 05:56 AM PST

Scientists have discovered a potential molecular link between Irisin, a recently identified hormone released from muscle after bouts of exercise, and the aging process. Irisin, which is naturally present in humans, is capable of reprograming the body's fat cells to burn energy instead of storing it. This increases the metabolic rate and is thought to have potential anti-obesity effects. The finding provides a potential molecular link between keeping active and healthy aging with those having higher Irisin levels more 'biological young' than those with lower levels of the hormone.

Small non-coding RNAs could be warning signs of cancer

Posted: 17 Feb 2014 05:52 AM PST

Small non-coding RNAs can be used to predict if individuals have breast cancer conclude researchers who contribute to The Cancer Genome Atlas project. The results indicate that differences in the levels of specific types of non-coding RNAs can be used to distinguish between cancerous and non-cancerous tissues. These RNAs can also be used to classify cancer patients into subgroups of individuals that have different survival outcomes.

Bacterial superbug protein structure solved

Posted: 17 Feb 2014 05:48 AM PST

Scientists have deciphered the 3-D structure of a protein that confers antibiotic resistance from one of the most worrisome disease agents: a strain of bacteria called methicillin-resistant Staphylococcus aureus (MRSA), which can cause skin and other infections. The team's findings may be an important step in combating the MRSA public health threat over the next 5 to 10 years.

Uncovering the secrets of tularemia, 'rabbit fever'

Posted: 17 Feb 2014 05:48 AM PST

Tularemia, aka "rabbit fever," is endemic in the northeastern United States, and is considered to be a significant risk to biosecurity -- much like anthrax or smallpox -- because it has already been weaponized in various regions of the world. Biologists are working to uncover the secrets of the bacterium Francisella tularensis, which causes tularemia.

Vitamin D provides relief for those with chronic hives, study shows

Posted: 17 Feb 2014 05:48 AM PST

Vitamin D as an add-on therapy could provide some relief for chronic hives, a condition with no cure and few treatment options, new research indicates. An allergic skin condition, chronic hives create red, itchy welts on the skin and sometimes swelling. They can occur daily and last longer than six weeks, even years. The two-year study looked at the role of over-the-counter vitamin D3 as a supplemental treatment for chronic hives. Over 12 weeks, 38 study participants daily took a triple-drug combination of allergy medications (one prescription and two over-the-counter drugs) and vitamin D3. Researchers found after just one week, the severity of patients' symptoms decreased by 33 percent. For patients that took a stronger dose of vitamin D3, a further 40 percent decrease in severity of their hives was noted.

Potential options for attacking stem cells in triple-negative breast cancer

Posted: 17 Feb 2014 05:48 AM PST

A protein that fuels an inflammatory pathway does not turn off in breast cancer, new research shows, resulting in an increase in cancer stem cells. This provides a potential target for treating triple negative breast cancer, the most aggressive form of the disease. The researchers identified a protein that is highly expressed in normal cells but undetectable in triple-negative breast cancer. They showed that this protein is degraded in cancers, blocking the cellular off-switch of a feedback loop involving an inflammatory protein. When the switch does not get turned off, it enables cancer stem cells to grow.
