The experimental aircraft designed to quiet the sonic boom is nearing its first supersonic flight, a pivotal moment for the future of civilian supersonic travel.
X-59 is approaching its first supersonic flight under NASA's Quesst program.
The aircraft is designed to reduce the sonic boom to around 75 decibels at ground level.
Flight data will be used to challenge existing bans on civilian supersonic overland travel.
A power plant in northeastern Brazil is running the world's first large-scale test of bioethanol as a primary fuel for industrial electricity generation.
World's first power plant to test sugarcane bioethanol as a replacement for heavy fuel oil.
The Wärtsilä 32M engine weighs around 100 tonnes; the trial will last two years.
Brazil leads global sugarcane ethanol production, making it the natural testing ground.
Long associated with bodybuilders, creatine is now drawing interest from neurologists and aging researchers — but experts urge caution before the hype gets ahead of the evidence.
Creatine is now being studied for cognitive benefits, not just muscle gain.
Brain-related benefits are best documented in older adults and vegetarians, not the general population.
Experts call for large clinical trials before any public health recommendation can be made.
The largest neuroimaging study of its kind, conducted in Singapore, has found structural brain changes linked to prolonged night-shift work, particularly among healthcare workers.
The largest neuroimaging study on night-shift work to date, conducted in Singapore.
Structural brain changes worsen proportionally with years of nocturnal work.
