The risk of experiencing an oxygen deficit at birth (birth asphyxia) increases for babies born to women who are overweight or obese, according to a study by Swedish and US researchers published in the journal PLOS Medicine. “These findings are important given the high prevalence of overweight and obesity worldwide, and suggest that preventing women of reproductive age from becoming overweight or obese is important to the health of their children”, says Dr. Martina Persson at Karolinska Institutet’s Department of Medicine, Solna, Clinical Epidemiology Unit, who led the study.

Scientific research at UT Southwestern Medical Center previously discovered that the newborn animal heart can heal itself completely, whereas the adult heart lacks this ability. New research by the same team today has revealed why the heart loses its incredible regenerative capability in adulthood, and the answer is quite simple – oxygen.

When a fetal heartbeat pattern becomes irregular during labor, many practitioners give oxygen to the mother. But questions remain whether this oxygen supplementation benefits the fetus or may actually be potentially harmful.

Due to the fluctuating availability of solar energy, storage solutions are urgently needed. One option is to use the electrical energy generated inside solar cells to split water by means of electrolysis, in the process yielding hydrogen that can be used for a storable fuel. Researchers at the HZB Institute for Solar Fuels have modified so called superstrate solar cells with their highly efficient architecture in order to obtain hydrogen from water with the help of suitable catalysts. This type of cell works something like an "artificial leaf."

Some six years ago scientific textbooks had to be updated because of the surprising discovery made by the research group led by Frank Keppler that plants produce methane in an oxygen-rich environment. At that time this was unthinkable, since it was commonly accepted that biogenic methane could only be formed during the decomposition of organic material under strictly anoxic conditions. His group has now made another fascinating new observation: fungi produce methane.

Working with researchers in the US and Germany, Johannes Messinger at Umeå University is opening new avenues to understand photosynthesis and create artificial photosynthesis. Using x-ray analysis, they have managed to see the structure of molecules under conditions where photosynthesis can occur, and they have also found that calcium plays a critical role in decomposing water.
