New insights into bacterial substitute for sex

New insights into bacterial substitute for sex

Bacteria don’t have sex as such, but they can mix their genetic material by pulling in DNA from dead bacterial cells and inserting these into their own genome. New research led by Imperial College London has found that this process — called recombination — is more complex than was first thought. The findings, published today in PLoS Genetics , could help us understand why bacteria which cause serious diseases are able to evade vaccines and rapidly become drug-resistant. Continue reading

Saving crops, people with inexpensive bug sensors

Saving crops, people with inexpensive bug sensors

University of California, Riverside researchers have created a method that can classify different species of insects with up to 99 percent accuracy, a development that could help farmers protect their crops from insect damage and limit the spread of insect-borne diseases, such as malaria and Dengue fever. Over the past 60 years, insect classification research has been limited by factors including an overreliance on acoustic sensing devices, a heavy focus on wingbeat frequency and limited data Continue reading

Cyber buddy is better than ‘no buddy’

Cyber buddy is better than ‘no buddy’

A Michigan State University researcher is looking to give exercise enthusiasts the extra nudge they need during a workout, and her latest research shows that a cyber buddy can help. The study, which appears in the Games for Health Journal , is the first to indicate that although a human partner is still a better motivator during exercise, a software-generated partner also can be effective Continue reading

Dog ownership benefits families of children with autism

Dog ownership benefits families of children with autism

Many families face the decision of whether to get a dog. For families of children with autism, the decision can be even more challenging. Now, a University of Missouri researcher has studied dog ownership decisions in families of children with autism and found, regardless of whether they owned dogs, the parents reported the benefits of dog ownership included companionship, stress relief and opportunities for their children to learn responsibility.

Low vitamin D linked to fatty liver disease in UK children

Low vitamin D linked to fatty liver disease in UK children

A UK studyi investigating the link between low vitamin D status and non-alcoholic fatty liver disease (NAFLD) in British children has identified a genetic variant associated with the disease’s severity. The research, conducted by the King’s College Hospital Paediatric Liver Centre and the University of Surrey’s School of Biosciences and Medicine, and funded by the Children’s Liver Disease Foundation retrospectively analysed the medical records of 120 paediatric patients with NAFLD. The findings could carry significant implications for UK clinicians in light of the nation’s rising number of childhood NAFLD cases. Continue reading

Stressful environments genetically affect African American boys

Stressful environments genetically affect African American boys

Stressful upbringings can leave imprints on the genes of children as young as age 9, according to a study led by Princeton University and Pennsylvania State University researchers. Such chronic stress during youth leads to physiological weathering similar to aging. A study of 40 9-year-old black boys, published in the Proceedings of the National Academy of Sciences , shows that those who grow up in disadvantaged environments have shorter telomeres — DNA sequences that generally shrink with age — than their advantaged peers Continue reading

Small cash incentives dramatically improve hepatitis B vaccination rates among injecting drug users

Small cash incentives dramatically improve hepatitis B vaccination rates among injecting drug users

Small financial incentives, totalling as little as £30, can dramatically increase the likelihood of people who inject drugs completing a course of hepatitis B virus (HBV) vaccination, according to new research published in The Lancet . Researchers in the UK found that people undergoing treatment for heroin addiction who received a maximum total of £30 supermarket vouchers in equal or graduated installments in return for full compliance with a regimen of three HBV vaccine injections were at least 12 times as likely to complete the course within 28 days compared to those not receiving a financial incentive (45% for equal payment installments and 49% for graduated payment installments vs 9% for no payment incentive). The study was led by Professor John Strang from the National Addiction Centre at King’s College London, UK, working in close collaboration with senior colleagues at Imperial College London and University College London (UCL), in the UK Continue reading
