A repeated antibiotic therapy not only makes the bacteria resistant to drugs, but also helps them to reproduce faster than before. It is found by scientists from the University of Exeter. The scientists carried out a study on E.coli, which can cause severe abdominal pain, diarrhea and renal failure in people, The Hans India reports.

Scientists from the University of Sydney have designed a unique patch to prevent sunburn. The patch will inform a person when it is necessary to hide from the sun or re-apply sunscreen, The Sydney Morning Herald reports.

Scientists from London Royal College have tested 9.8 million genetic variants in 420,000 people. The experts have found 107 new genes associated with high blood pressure. A lot of these 107 genes were expressed in large volumes in vascular and cardiovascular tissues.

Scientists from the University of Pennsylvania have performed a study on mice with autism. The test animals took D-cycloserine, which is normally used for tuberculosis. Due to this remedy the rodents improved their social skills, UPI.com reports.

Scientists from the Trinity College Dublin have found a molecule that is important for cell growth. As it turned out, this molecule - STAT3 - also protects against infections, Eurek Alert reports. This discovery will restore the human immune system and build a protection against a range of viruses.

A targeting effect on tau protein tangles in mice with symptoms similar to Alzheimer's disease allowed to reverse the brain damage, slow down the memory loss and increase the lifespan of rodents, New Scientist reports. It is known that two kinds of deposits of sticky proteins such as beta-amyloid deposits and tau protein tangles are observed in the brains of people with Alzheimer's disease.

According to scientists, cholesterol is necessary for the normal brain activity. But due to diabetes the brain cholesterol concentrations can be reduced. This is proved by experiments in mice. The scientists suppressed cholesterol production in the brain in rodents. After that, neurological disorders have appeared in the animals, Medical Xpress reports.

Cerebral hypoxia is one of the most common brain pathologies in premature infants, which damages white matter. White matter consists of fibers that connect different parts of the brain. The damaged white matter disturbs the signal transmission inside the brain and between the brain and other organs.

The scientists of the University of Oregon have revealed a molecule which is capable to neutralize the bacteria resistance to antibiotics, Xinhua reports. This molecule is known as PPMO (phosphorodiamidate morpholino oligomer). It inhibits the activity of NDM-1 enzyme which makes the bacteria resistant to penicillin.

Most of all Vitamin E is needed for the people with metabolic syndrome. This vitamin is an antioxidant and it is essential for the protection of cells, Xinhua reports. Metabolic syndrome can include several specific diseases or abnormalities, such as: abdominal obesity, increased blood lipids, high blood pressure, inflammation, thrombosis, insulin resistance or impaired glucose tolerance.
