A study of risk communication as it relates to altruistic behavior has found that portraying an event as a distant risk, despite highlighting its importance and potential progression, fails to prompt altruistic behavior intention among the U.S. public.
The Ebola outbreak in West Africa gained substantial media momentum during the final three months of 2014. In October, a Liberian man visiting family in Texas became the first diagnosed Ebola patient in the U.S. to die from the disease. But though mainstream media hyped it beyond belief, the Obama administration offered minimal assistance to the affected region, at least compared to American responses to other recent crises or disasters, such as the Haitian earthquake in 2010.

The Supreme Court is set to consider Whole Woman's Health v. Cole, which addresses two Texas laws related to abortion clinics.

Citizen science, amateurs who did science for the love of it rather than as a career, were once well-respected. They were often more elite than those who did it as an occupation, much like Sherlock Holmes was a superior detective because he was an amateur in a world where police forces were blue collar and lacked education. 

Washington, D.C., January 12, 2016 - As we continue to shrink electronic components, top-down manufacturing methods begin to approach a physical limit at the nanoscale. Rather than continue to chip away at this limit, one solution of interest involves using the bottom-up self-assembly of molecular building blocks to build nanoscale devices.

A team of astronomers led by Tomoharu Oka, a professor at Keio University in Japan, has found an enigmatic gas cloud, called CO-0.40-0.22, only 200 light years away from the center of the Milky Way. What makes CO-0.40-0.22 unusual is its surprisingly wide velocity dispersion: the cloud contains gas with a very wide range of speeds. The team found this mysterious feature with two radio telescopes, the Nobeyama 45-m Telescope in Japan and the ASTE Telescope in Chile, both operated by the National Astronomical Observatory of Japan.

A new study from the Medical Research Council Lifecourse Epidemiology Unit, University of Southampton, shows lesions, which can best be seen on MRI scans, could help identify individuals who are more likely to suffer from more rapidly progressing osteoarthritis.
Osteoarthritis is the most common type of arthritis in the UK and can cause the joints to become painful and stiff. Almost any joint can be affected, but it most often causes problems in the knees, hips, and small joints of the hands. It can progress at varying speeds.

Occupational exposure to textile dust is associated with a more than doubling in the risk of developing rheumatoid arthritis, finds research published online in the Annals of the Rheumatic Diseases.
And it is also linked to a heightened risk of genetic susceptibility to the risk of developing antibodies to rheumatoid arthritis, known as ACPA, which hasten progression of the disease.
This is the first time that such associations have been identified, say the researchers.
The researchers base their findings on 910 Malaysian women who had been diagnosed with early stage rheumatoid arthritis and 910 women of similar age, but free of the disease.

Spending time in close contact with others often means risking catching germs and getting sick. But being sociable may also help transmit beneficial microbes, finds a multi-institutional study of gut microbiomes in chimpanzees.
Researchers based at The University of Texas at Austin, Duke University, The University of California, Berkeley and other institutions monitored changes in the gut microbes and social behavior of wild chimpanzees. Their research -- linked to a population of chimpanzees studied over eight years in Gombe National Park, Tanzania -- found that the number of bacteria species in each chimp's GI tract increases when the chimps are more gregarious.
The results help scientists better understand the factors that maintain a healthy gut microbiome.

The fatal shooting of Michael Brown on Aug. 9, 2014, in Ferguson, Missouri, set off a national wave of dialogue and protests, from the streets to social media, as people nation­wide grappled with myriad complex issues, including police use of force, race relations in America, and criminal justice reform.
Now, new research from two Northeastern University professors shows that in the days following Brown's shooting, everyday citizens--not politicians, celebrities, or other prominent public figures--were the ones who, using Twitter, shaped the national conversation. African Americans with close ties to the Ferguson area, they found, played a particularly influential role on the day of the incident.

Researchers from the Cancer Research Center of Toulouse have conducted the first comprehensive review on dendrogenin A (DDA). DDA is a steroidal alkaloid arising from cholesterol and histamine cross-metabolization that they recently discovered. Importantly, they found that DDA is a tumor suppressor metabolite. Thus 100 years after the discovery of all-trans-retinoic acid, DDA appears as a rare example human metabolite promised to extensive basic research studies and clinical developments.

Imagine a virus so serious the government recommends that women stop getting pregnant.
It exists, and it is now in Brazil, which is a big concern as the Olympics approaches. The Zika virus, native to parts of Africa and Asia, has been spreading locally among people who have not traveled abroad. There is no vaccine against the virus or antiviral treatment.

Zika is generally a mild illness, spread by a day-biting mosquito. However, there is a worrisome, but as of yet unproven, association of infected mothers in Brazil giving birth to babies with small heads and underdeveloped brains, Dr. Khan said. There has been a 20-fold increase in the number of babies born with this condition, known as microcephaly, since Zika first appeared in Brazil in May 2015.

Meeting patients' preferences for the time and place of their psychological treatment may affect their perception of treatment outcome, a cross-sectional survey by researchers from the Royal College of Psychiatrists and Imperial College London involving 14,587 respondents suggests.
