Trial shows that the antibiotic azithromycin does not prevent mild COVID-19 cases progressing to hospitalization or death
A new study (the ATOMIC2 trial), presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) and published simultaneously in The Lancet Respiratory Medicine, shows the antimicrobial drug azithromycin - already approved for use in multiple infections - does not prevent mild COVID-19 cases progressing to hospitalisation or death.
Turn off the blue light!
Researchers from University of Tsukuba have found that exposure to specific types of light before sleep can have variable effects on energy metabolism during sleep. Specifically, participants who went to sleep after exposure to organic light-emitting diodes (OLEDs), which emit polychromatic white light that contains less blue light than light-emitting diodes (LEDs), exhibited significantly...
UCPH researchers prove powerhouse malfunction as the major cause of Parkinson's Disease
The major cause of Parkinson's Disease is a dysregulation of immune genes central for fighting against viruses, a new study reveals. Researchers from the University of Copenhagen show that this dysregulation leads to a malfunction in the cell's powerhouse, which cannot produce sufficient energy for neurons to stay alive, causing them to gradually die.
Using mice to open the way to prevent blocked arteries
Researchers from Tokyo Medical and Dental University (TMDU) have identified important parts of the pathway by which a high-fat diet affects the body's immune response, leading eventually to atherosclerosis. Working with mouse models, they clarified how histone H3 citrullination activates neutrophils with serum CXCL1 elevation. Identifying these steps could lead to new diagnostic tools and...
Virtual learning may help NICU nurses recognize baby pain
Babies younger than four weeks old, called neonates, were once thought not to perceive pain due to not-yet-fully-developed sensory systems, but modern research says otherwise, according to researchers from Hiroshima University in Japan.
Vocal music boosts the recovery of language functions after stroke
Listening to vocal music is a simple and cost-efficient way of promoting recovery and brain health after a stroke.
Storm brews over South African ship-based energy plan
Floating power plants raise concerns over jobs and environmental risks as South Africa closes in on energy deal.

Longest known continuous record of the Paleozoic discovered in Yukon wilderness
- ScienceDaily
- 21/7/9 00:59
Expeditions to a remote area of Yukon, Canada, have uncovered a 120-million-year-long geological record of a time when land plants and complex animals first evolved and ocean oxygen levels began to approach those in the modern world.
Goldilocks planets 'with a tilt' may develop more complex life
Planets which are tilted on their axis, like Earth, are more capable of evolving complex life. This finding will help scientists refine the search for more advanced life on exoplanets. This NASA-funded research is presented at the Goldschmidt Geochemistry Conference.
Early Earth was bombarded by series of city-sized asteroids
Scientists know that the Earth was bombarded by huge impactors in distant time, but a new analysis suggests that the number of these impacts may have been 10 times higher than previously thought. This translates into a barrage of collisions—similar in scale to that of the asteroid strike that wiped out the dinosaurs—on average every 15 million years between 2.5 and 3.5 billion years ago. Some...
