Contact investigation for imported case of Middle East respiratory syndrome, Germany

On March 19, 2013, a patient from United Arab Emirates who had severe respiratory infection was transferred to a hospital in Germany, 11 days after symptom onset. Infection with Middle East respiratory syndrome coronavirus (MERS-CoV) was suspected on March 21 and confirmed on March 23; the patient, who had contact with an ill camel shortly […]

Pathology of US porcine epidemic diarrhea virus strain PC21A in gnotobiotic pigs

To understand the progression of porcine epidemic diarrhea virus infection, we inoculated gnotobiotic pigs with a newly emerged US strain, PC21A, of the virus. At 24–48 hours postinoculation, the pigs exhibited severe diarrhea and vomiting, fecal shedding, viremia, and severe atrophic enteritis. These findings confirm that strain PC21A is highly enteropathogenic. A highly contagious coronavirus […]

Biodegradable battery could melt inside the body

A four-cell battery made of biodegradable materials completely dissolves after three weeks in water. A biodegradable, implantable battery could help in the development of biomedical devices that monitor tissue or deliver treatments before being reabsorbed by the body after use. “This is a really major advance,” says Jeffrey Borenstein, a biomedical engineer at Draper Laboratory, […]

Brain-mapping projects to join forces

The US brain-research programme aims to create tools to image and control brain activity, while its European counterpart hopes to create a working computational model of the organ. It seems a natural pairing, almost like the hemispheres of a human brain: two controversial and ambitious projects that seek to decipher the body’s control center are […]

Immunology: A tolerant approach

Despite a long record of failure, a few immunologists continue to pursue precisely targeted therapies for autoimmune diseases. Ever since Ed Wiley learned that he had type 1 diabetes in 1997, he has fretted over his meals, blood glucose levels and the daily programming of his insulin pump. Wiley, a statistician who lives outside Boulder, […]

Misleading mouse studies waste medical resources

A running joke among health researchers is that everything has been cured — in mice. However that may not be always true. The failure of experimental drugs that had once looked promising could have been prevented with better animal studies, according to a re-examination of past clinical trials. “I hear too many stories about patients […]

Mutations explain poor showing of 2012 flu vaccine

In November 2012, as an early and severe flu season bore down on North America, the news from the US Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia, was reassuring. “So far, this season, most (90%) of the influenza viruses … are well-matched to the 2012–2013 influenza vaccine; this should mean that the […]

Animals losing migratory routes? Devasting consequences of scarcity of ‘knowledgeable elders’

Small changes in a population may lead to dramatic consequences, like the disappearance of the migratory route of a species. Until the ’50s, bluefin tuna fishing was a thriving industry in Norway, second only to sardine fishing. Every year, bluefin tuna used to migrate from the eastern Mediterranean up to the Norwegian coasts. Suddenly, however, […]

Climate change will improve survival rates of British bird — the long-tailed tit

Climate change may be bad news for billions, but scientists at the University of Sheffield have discovered one unlikely winner — a tiny British bird, the long-tailed tit. Like other small animals that live for only two or three years, these birds had until now been thought to die in large numbers during cold winters. […]

Dying cells in fruit fly alert neighboring cells to protect themselves: As a result, neighbors become harder to kill

Cells usually self-destruct when irreparable glitches occur in their DNA. Programmed cell death, or apoptosis, helps insure that cells with damaged DNA do not grow and replicate to produce more mutated cells. Apoptosis thereby helps protect and insure the survival of the organism. At the GSA Drosophila Research Conference, TinTin Su, Ph.D., will report that […]
