Researchers have clarified the crucial catalytic step in the production of hydrogen by enzymes. The enzymes, called [FeFe]-hydrogenases, efficiently turn electrons and protons into hydrogen. They are thus a candidate for the biotechnological production of the potential energy source.
Plans to create 100 new 'smart' cities in India to support the country's rapidly growing urban population could have a significant detrimental impact on the environment unless greater emphasis is placed on providing new supporting infrastructure and utilities, according to a major new study.
Changes in the brain's structure that could be the result of depression have been identified in a major scanning study.
Studies of naturally carbonated mineral water have given scientists insight on how to locate hot water springs -- potential sources of sustainable geothermal energy.
Certain personality traits appear more likely to lead to future mental illness, while others seem to protect against it. Emerging research builds a stronger case for this connection between personality and mental health.
Ion channels in the membrane vesicles that mediate intracellular protein transport play a crucial role in cell physiology. A method now allows them to be studied with greater specificity than ever before.
Biochemists have elucidated the structure of an enzyme that supplies carotenoid, investigators report. The lack of vitamin A in food is a major cause of health problems worldwide and can lead to blindness and even death. This is especially a problem in threshold or third-world countries, where children are likely to suffer from a lack of vitamin A or its precursor beta-carotene due to malnourishment.
Archeologists are studying the impact of intercultural contacts in Ancient Egypt. New excavations in Sudan have uncovered a tomb dating to around 1450 BC on the island of Sai in the Nile.
Physical exercise seems beneficial in the prevention of cognitive impairment and dementia in old age, numerous studies have shown. Now researchers have explored in one of the first studies worldwide how exercise affects brain metabolism.
Parked vehicles can quickly become a life-threatening environment for unattended children or dogs during the summer months. Dangerous cabin temperatures can be reached in a matter of minutes. Researchers not only calculated the temperature rise but also developed a dynamic model that requires only three readily available parameters to predict this increase: outdoor air temperature, wind velocity and solar radiation. All three values are available on an hourly basis from standard meteorological stations.
