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.
Resurrecting ancient protein partners reveals origin 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.

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.
How waves of 'clutches' in the motor cortex help our brains initiate movement
- ScienceDaily
- 20/3/7 00:33
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.

In some cases of ineffective messaging, it might be appropriate, despite the aphorism to the contrary, to blame the messenger.
One species to four: New analysis documents new bird diversity in the Pacific
- ScienceDaily
- 20/3/7 00:31
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...
