New piece of Alzheimer's puzzle found

Scientists found two short peptides, or strings of amino acids, that when injected into mice with Alzheimer's disease daily for five weeks, significantly improved the mice's memory. The treatment also reduced some of the harmful physical changes in the brain that are associated with the disease.

Programmable swarmbots make flexible biological tools

Biomedical engineers have developed a new platform to create biological drugs using specially engineered bacteria that burst and release useful proteins when they sense that their capsule is becoming too crowded.

Peatlands trap CO2, even during droughts

Scientists studied the two species of moss that make up the peatland. They discovered that in hot weather and drought conditions, one species resists, whereas the other is negatively impacted. In wet weather conditions the opposite takes place. Peatland however survives in the end. Although peatlands make up only 3% of the Earth's surface, they store one third of CO2 present in soil. Preserving peatlands would therefore limit the impact of future climate change.

Deeper understanding of early life experiences can help combat chronic obesity and frequent bingeing

According to a new study, dysfunctional eating patterns and habits in overweight and obese adults can be triggered by early life experiences that are deeply rooted within patients' personality features.

Genomic migration analysis shows antibiotic resistance moving from humans to animals

New results show that human-acquired antibiotic resistance genes are being transmitted to livestock, companion animals and wildlife. Researchers analyzed a global set of 901 genome sequences of the bacteria Streptococcus agalactiae (aka group B Strep) from nine different host species — humans, cows, dogs, fish, frogs, gray seals, dolphins, goats and a camel — to better understand the transmission process. Streptococcus agalactiae can cause life-threatening illnesses.
