Oct. 14, 1947: Flying faster than sound

When Glamorous Glennis, an experimental Bell X-1 aircraft built to mimic the shape of a .50 caliber bullet, shot to 700 mph (1,127 km/h) with Air Force Captain Chuck Yeager inside, it paved the way for Americans to one day travel to space. On Oct. 14, 1947, the X-1 was launched from the bomb bay Continue reading "Oct. 14, 1947: Flying faster than sound" The post Oct. 14, 1947: Flying faster than sound appeared first on Astronomy Magazine .

Supercharged vitamin k could help the brain heal itself

Supercharged vitamin k could help the brain heal itself

Researchers have synthesized enhanced vitamin K analogues that outperform natural vitamin K in promoting neuron growth. The new compounds, which combine vitamin K with retinoic acid, activate the mGluR1 receptor to drive neurogenesis. They also efficiently cross the blood-brain barrier and show stability in vivo. This discovery could pave the way for regenerative treatments for Alzheimer’s and related diseases.

Scientists find the brain’s hidden pulse that may predict Alzheimer’s

Scientists find the brain’s hidden pulse that may predict Alzheimer’s

Researchers at USC have created the first method to noninvasively measure microscopic blood vessel pulses in the human brain. Using advanced 7T MRI, they found these tiny pulsations grow stronger with age and vascular risk, disrupting the brain’s waste-clearing systems. The discovery may explain how circulation changes contribute to Alzheimer’s and other neurodegenerative diseases.
