Food safety social media guide developed by researchers

Food safety social media guide developed by researchers

To help protect public health, researchers from North Carolina State University have developed guidelines on how to use social media to communicate effectively about food safety. “In a crisis context, the framework can be used by health officials, businesses or trade organizations affected by foodborne illness to help them reach key audiences with information that could be used to reduce the risk of foodborne illness,” says Dr Continue reading

New tools advance bio-logic

New tools advance bio-logic

Researchers at Rice University and the University of Kansas Medical Center are making genetic circuits that can perform more complex tasks by swapping protein building blocks. The modular genetic circuits engineered from parts of otherwise unrelated bacterial genomes can be set up to handle multiple chemical inputs simultaneously with a minimum of interference from their neighbors Continue reading

Students cope well with healthier snacks

Students cope well with healthier snacks

Students do not mind buying healthier snacks from vending machines, according to research published in the International Journal of Food Safety, Nutrition and Public Health . The findings could have implications for campus health initiatives as well as vendor profits. The common stereotype of the busy student is of someone who will grab a junk food snack between lectures and rarely chooses a decent, hot meal over a chance to share a beer or two with fellow students.

Declining intelligence in old age linked to visual processing

Declining intelligence in old age linked to visual processing

Researchers have uncovered one of the basic processes that may help to explain why some people’s thinking skills decline in old age. Age-related declines in intelligence are strongly related to declines on a very simple task of visual perception speed, the researchers report in the Cell Press journal Current Biology on August 4. The evidence comes from experiments in which researchers showed 600 healthy older people very brief flashes of one of two shapes on a screen and measured the time it took each of them to reliably tell one from the other.

Missing sleep may hurt your memory

Missing sleep may hurt your memory

Lack of sleep, already considered a public health epidemic, can also lead to errors in memory, finds a new study by researchers at Michigan State University and the University of California, Irvine. The study, published online in the journal Psychological Science , found participants deprived of a night’s sleep were more likely to flub the details of a simulated burglary they were shown in a series of images Continue reading

Offering option of initial HIV care at home increases use of antiretroviral therapy

Offering option of initial HIV care at home increases use of antiretroviral therapy

LSTM Researchers found that offering adults in Malawi optional home initiation of care following HIV self-testing resulted in a significant increase in the proportion of adults initiating antiretroviral therapy (ART) compared with standard HIV care. The results are part of a study that was funded by the Wellcome Trust and published in the July 23/30 issue of JAMA , which is HIV/AIDS themed and released early to coincide with the International AIDS Conference taking place in Melbourne, Australia next week. In 2012 it was estimated that 35 million people worldwide were living with the human immunodeficiency virus (HIV). Continue reading

Growth hormone analog may reduce risk of fatty liver disease in HIV-infected patients

Growth hormone analog may reduce risk of fatty liver disease in HIV-infected patients

In a preliminary study, HIV-infected patients with excess abdominal fat who received the growth hormone-releasing hormone analog tesamorelin for 6 months experienced modest reductions in liver fat, according to a study in the July 23/30 issue of JAMA , a theme issue on HIV/AIDS. Patients infected with HIV demonstrate a high prevalence of nonalcoholic fatty liver disease, estimated at 30 percent to 40 percent Continue reading
