A large-scale study analyzed 415,980 electronic medical records of older adults in England. People aged 75 or over with low blood pressure (below 130/80) had increased mortality rates in the follow-up, compared to those with normal blood pressure. This was especially pronounced in 'frail' individuals, who had 62% increased risk of death during the 10-year follow-up.
After reconstructing the ancient forms of two cellular proteins, scientists discovered the earliest known instance of a complex form of protein regulation.
Fishermen from California to Washington caught almost all the available legal-size male Dungeness crab each year in the last few decades. However, the crab population has either remained stable or continued to increase, according to the first thorough population estimate of the West Coast Dungeness stocks.
By observing humans, robots learn to perform complex tasks, such as setting a table.
When 119 young adults consumed a meal while playing a simple computer game for 15 minutes, they ate significantly less than when they ate the same meal without distractions.
Scientists have discovered that signals in the motor cortex act like a series of clutches when it comes to moving, and that these signals can be disrupted to slow the brain's initiation of movement.
A new study shows, for the first time, an experiment that could detect a class of ultra-high-energy neutrinos using radar echoes.
In some cases of ineffective messaging, it might be appropriate, despite the aphorism to the contrary, to blame the messenger.
New findings suggest several island bird populations in the Pacific that were previously designated as a single species actually comprise up to four distinct species. The results upend understanding of the islands' robin populations, which have been used as a textbook example of evolution since the 1940s. The new findings have important implications for conservation, as some of the...
Researchers have created a low-cost solar cell with one of the highest power-conversion efficiencies to date, by layering cells and using a unique combination of elements.
Before the Taqba Dam impounded the Euphrates River in northern Syria in the 1970s, an archaeological site named Abu Hureyra bore witness to the moment ancient nomadic people first settled down and started cultivating crops. A large mound marks the settlement, which now lies under Lake Assad.
