First steps to neutralizing Zika Posted: 24 Nov 2016 12:20 PM PST As Zika spreads throughout the world, the call for rapid development of therapeutics to treat Zika rings loud and clear. Taking a step further in identifying a possible therapeutic candidate, a team of researchers has discovered the mechanism by which C10, a human antibody previously identified to react with the Dengue virus, prevents Zika infection at a cellular level.

Upward mobility boosts immunity in monkeys Posted: 24 Nov 2016 12:13 PM PST The richest and poorest Americans differ in life expectancy by more than a decade. Glaring health inequalities across the socioeconomic spectrum are often attributed to access to medical care and differences in habits such as smoking, exercise and diet. But a new study in rhesus monkeys shows that the chronic stress of life at the bottom can alter the immune system even in the absence of other risk factors.

Researchers discover most winter boots are too slippery to walk safely on icy surfaces Posted: 24 Nov 2016 05:18 AM PST A team of researchers is dedicated to keeping Canadians safer this winter by offering evidence-based ratings on footwear that may reduce the risk of slips and falls on ice. The team has developed the first test of its kind in the world – the Maximum Achievable Angle (MAA) Testing Method – to validate slip resistant footwear on icy surfaces using real people in a simulated winter environment.

Antarctic explorers help make discovery 100 years after their epic adventures Posted: 24 Nov 2016 05:18 AM PST Heroes of Antarctic exploration have played a crucial role in research that suggests the area of sea ice around Antarctica has barely changed in size in 100 years. Ice observations recorded in the ships' logbooks of explorers such as the British Captain Robert Scott and Ernest Shackleton and the German Erich von Drygalski have been used to compare where the Antarctic ice edge was during the Heroic Age of Antarctic Exploration (1897--1917) and where satellites show it is todayed to attempt the first ever cross-Antarctic trek.

Why are black men missing from prostate cancer research? Posted: 24 Nov 2016 05:17 AM PST Black men are three times more likely to develop prostate cancer than other demographics, yet black men are consistently underrepresented in research studies, say researchers.

Researchers define, for the first time, how the cancer cell of origin controls invasive, metastatic properties of tumor cells Posted: 24 Nov 2016 05:17 AM PST For the first time, scientists define how the cancer cell of origin controls invasive and metastatic properties of tumor cells.

Human cells with a 'built-in circuit' help prevent tumor growth Posted: 24 Nov 2016 05:17 AM PST Researchers have engineered cells with a 'built-in genetic circuit' that produces a molecule that inhibits the ability of tumors to survive and grow in their low oxygen environment. The genetic circuit produces the machinery necessary for the production of a compound that inhibits a protein which has a significant and critical role in the growth and survival of cancer cells. This results in the cancer cells being unable to survive in the low oxygen, low nutrient tumor micro-environment.

Toxoplasma's balancing act explained Posted: 24 Nov 2016 05:16 AM PST The parasite Toxoplasma gondii is a silent success. It infects up to 95% of people in many regions of the world, and most of them never know it, due to the parasite's artful manipulation of its host's immune response. Toxoplasma keeps the immune response low enough so that it can thrive, but high enough so that its human hosts generally live healthy lives and can incubate parasites. Scientists have uncovered one of the ways it maintains this balance.

Depression in young people affects the stomach, anxiety the skin Posted: 24 Nov 2016 05:16 AM PST Mental disorders and physical diseases frequently go hand in hand. For the first time, psychologists have identified temporal patterns in young people: arthritis and diseases of the digestive system are more common after depression, while anxiety disorders tend to be followed by skin diseases.

Diagnostic tool designed for Familial Mediterranean Fever Posted: 24 Nov 2016 05:16 AM PST Researchers have developed a tool to diagnose Familial Mediterranean Fever (FMF). Particularly common among Mediterranean populations, this genetic disease is characterized by inflammation, fever and severe pain. Because of its complex diagnosis, patients often remain untreated for many years, which can eventually lead to kidney failure.

Consumer of the future will use a mobile phone to monitor environment Posted: 24 Nov 2016 05:15 AM PST The world's first hyperspectral camera has been developed by converting an iPhone camera into a new kind of optical sensor. This will bring the new possibilities of low-cost spectral imaging to consumer applications. Consumers will be able to use their mobile phones for example to sense food quality or monitor health.

Creative activities promote day-to-day wellbeing Posted: 23 Nov 2016 03:39 PM PST Everyday creative activity may lead to an "upward spiral" of increased wellbeing and creativity in young adults, new research suggests. In their study, researchers asked 658 university students to keep a daily diary of their experiences and emotional states over 13 days.

In highly lethal type of leukemia, cancer gene predicts treatment response Posted: 23 Nov 2016 03:38 PM PST Patients with the most lethal form of acute myeloid leukemia (AML) – based on genetic profiles of their cancers – typically survive for only four to six months after diagnosis, even with aggressive chemotherapy. But new research indicates that such patients, paradoxically, may live longer if they receive a milder chemotherapy drug.

Generation X at greater risk of stroke than baby boomers Posted: 23 Nov 2016 02:05 PM PST Older baby boomers—those born between 1945 and 1954—are the "stroke-healthiest generation," according to a new study that found the lowest incidence of ischemic stroke in this age group within the past 20 years. In contrast, the rate of stroke more than doubled in Generation X, people born between 1965 and 1974, during the same time period.

Active-duty military find PTSD relief through individual cognitive therapy Posted: 23 Nov 2016 11:36 AM PST Although both group and individual therapy can ease post-traumatic stress disorder (PTSD) symptoms in active-duty military service members, individual therapy relieved PTSD symptoms better and quicker, according to a study.

World of viruses uncovered Posted: 23 Nov 2016 11:33 AM PST A pioneering study of invertebrates has discovered 1,445 viruses, including several new families, revealing people have only scratched the surface of the world of viruses.

Fibroblasts could provide new target for treatment of rheumatoid arthritis Posted: 23 Nov 2016 11:28 AM PST A new study reveals the key role of different types of fibroblast cells in the development of rheumatoid arthritis (RA), opening up a new avenue for research into treatment of the disease. Synovial Fibroblasts (SFs) are cells that make up part of the connective tissue, or synovium, around human joints. In RA patients, SF cells cause damage by invading and attacking the cartilage and bone around the joint.

Study in rats finds low blood alcohol levels have no effect on total calories consumed Posted: 23 Nov 2016 11:27 AM PST Laboratory rats will drink alcohol if it's available, and may even get a little tipsy, researchers report in a new study. But they won't voluntarily drink until they're drunk. And while ethanol is calorie-rich, rats that drink it eat less food and their total energy intake remains steady, the research team found.

Missed connections: As people age, memory-related brain activity loses cohesion Posted: 23 Nov 2016 11:18 AM PST Groups of brain regions with coordinated activity are consistent for individuals, but shrink with age, report scientists.

Jet lag and obesity share similar pathways to liver cancer Posted: 23 Nov 2016 11:14 AM PST Since 1980, the incidence of hepatocellular carcinoma, the most common type of liver cancer, has nearly tripled, and obesity related liver disease is one of the driving forces behind the increasing number of cases. Researchers are now examining how other lifestyle factors may affect your health. Using mice, the scientists show that repeated jet lag increases both obesity related liver disease and the risk of liver cancer.

Mutant prion protein could help reveal neurodegenerative disease mechanisms Posted: 23 Nov 2016 11:13 AM PST For the first time, scientists have isolated a mutated prion protein that can multiply in the lab but not in living animals, according to a study. The mutant prion provides new insights into the mechanisms that make prions infectious, say researchers.

Turning back the aging clock Posted: 22 Nov 2016 09:36 AM PST A new approach to removing cellular damage that accumulates with age has been developed by scientists. The technique can potentially help slow or reverse an important cause of aging, say researchers.

Do stress and strain lead to deviant behavior? Posted: 22 Nov 2016 09:26 AM PST Chances are good that youngsters growing up around family members who gamble will also start doing so to release the strains of daily living. This is not necessarily true for adolescents whose family members find their escape in alcohol or drugs. Given that gambling and substance abuse are both potentially addictive, and often go hand in hand, this is a significant finding and one of the many results of a new study just published.

Reshaping our ideas of bacterial evolution Posted: 22 Nov 2016 09:26 AM PST The shape of bacteria does not influence how well they can move. This is the surprising finding of new research which could have major implications for the future of the scientific and medical industries. The results refute long-held theories that there should be a strong link between the evolution of shape in bacteria and their ability to move.

How do you mend a broken heart? Posted: 22 Nov 2016 09:25 AM PST Researchers use zebrafish to help mammalian hearts regenerate, including promising results in human heart cells in vitro, outlines a new report.
