Scientists last autumn revealed that the gas phosphine was found in trace amounts in Venus’ upper atmosphere. That discovery promised the slim possibility that phosphine serves as a biological signatu...
Oxygen first accumulated in the Earth's atmosphere about 2.4 billion years ago, during the Great Oxidation Event. A long-standing puzzle has been that geologic clues suggest early bacteria were photos...
Vlcek M., Andrlikova M., Barbato O., Bina V., Boland M.P., Dolezel R., Lopatarova M., Cech S. (2017): Supplementation of dairy cows with docosahexaenoic acid did not affect ovarian activity. Czech J....
Recently, Skrede et al. (1) prospectively examined the association of objectively measured sedentary time and subcomponents of physical activity with individual and clustered cardiometabolic risk fact...
Sr released into seawater from nuclear bomb testing and nuclear facility accident sites requires long-term monitoring. However, measuring 90Sr in seawater is still difficult and time-consuming. This ...
Over the past few years, a large fracture has grown across a large floating ice shelf on the Antarctic Peninsula. The world is watching the ice shelf, now poised to break off an iceberg the size of De...
Background: Altered body composition in children with cerebral palsy (CP) could be due to differences in energy intake, habitual physical activity (HPA), and sedentary time.
Background: Musculoskeletal injuries are the most common complaint in active populations. More than 50% of all injuries in sports can be classified as sprains, strains, ruptures, or breaks of musculos...
An ongoing challenge for scientists working to understand the brain is being able to see all its parts. Researchers have spent centuries developing better imaging techniques to see beyond the abilitie...
Background: The effect of intensity and duration of physical activity (PA) on weight loss has been well described. However, the effect of the frequency of weekly PA on weight loss is still unknown.
The EuroQSAR Symposia have been taking place since 1973 and constitute major scientific events in the field of computational drug design, with further applications in agricultural and environmental sc...
In this experiment, we proposed and implemented a disease forecasting system using a received signal strength indication ZigBee-based wireless network with a 3-axis acceleration sensor to detect illne...
This study was conducted to observe antioxidant enzyme activity, iron content and lipid oxidation of Korean native chickens and other poultry. The breast and thigh meat of three Korean native chicken ...
