Cholera strain in Haiti matches bacteria from south Asia

A recent study found that the cholera strain in Haiti matches bacterial samples from South Asia, contradicting earlier assumptions of its Latin American origin. The researchers believe the strain was introduced into Haiti through human activity, raising hopes for control measures such as vaccination and rapid screening.

Gene hunters tackle crop diseases

Scientists have sequenced the genomes of parasitic water fungus and water molds that cause late blight in potatoes, tomatoes, and downy mildew in cruciferous vegetables. The analysis reveals that some sections of the genome are slow to evolve, allowing for resistance genes to be targeted.

Better batteries from the bottom up

Rice University researchers have developed microbatteries with nanowire 'hearts' that can store more energy and charge faster than traditional lithium-ion batteries. The batteries employ vertical arrays of nickel-tin nanowires encased in a PMMA polymer, which insulates the wires and allows ions to pass through.

Computer-based program may help relieve some ADHD symptoms in children

A new study suggests an intensive computer-based working memory training program can alleviate some ADHD symptoms in children. The five-week program showed significant changes in attention, organization, and working memory skills. Parents reported improvements in ADHD symptoms, and the results were evident four months after treatment.

IU study: When to end a run

A study by Indiana University found that runners who continue despite exhaustion change their form, increasing the risk of injury. The study showed that at the end of a normal run, runners' mechanics start to change when they reach fatigue levels, typically indicated by RPEs between 13-15.

Living in certain neighborhoods increases the chances older men and women will develop cancer

A new study found that living in racially segregated neighborhoods with high crime rates increases the chances of developing cancer, particularly among older adults. The research, published in the American Journal of Public Health, also discovered a link between neighborhood segregation and heart problems for older women.

UCLA researchers find that Medicaid-funded ADHD treatment for children is failing

A study by UCLA researchers found that Medicaid-funded ADHD treatment for children yielded poor quality care, with few follow-up visits and inadequate medication use. The study suggests areas for improvement in ADHD care, including better alignment of clinical severity with provider type and increased use of stimulant medication.
