Psychedelic brew ayahuasca’s profound impact revealed in brain scans
Study gives most advanced picture yet of DMT compound’s effect on advanced functions such as imaginationThe brew is so potent that practitioners report not only powerful hallucinations, but near-death experiences, contact with higher-dimensional beings, and life-transforming voyages through alternative realities. Often before throwing up, or having trouble at the other end.Now, scientists have...

Shigellosis, a highly contagious diarrheal disease, is caused by Shigella bacteria circulating in industrializing countries but also in industrialized countries. Scientists who have been monitoring Shigella in France for several years have detected the emergence of extensively drug-resistant (XDR) strains of Shigella sonnei.

Researchers have found that the spread of the spotted lanternfly population is largely due to human-mediated dispersal via transportation. In other words, these expert hitchhikers are catching rides on our cars, trucks and trains.
Gigapixel 3D microscope captures life in unprecedented detail

Researchers have developed a new type of microscope that stitches together video from 54 individual cameras and lenses. Whether recording high-speed, 3D, gigapixel movies of the behavior of dozens of freely swimming zebrafish or the grooming activity of fruit flies at near cellular-level detail across a very wide field of view, the device is opening new possibilities to researchers the world over.
Study uses base editing to correct mutation that causes rare immune deficiency
- ScienceDaily
- 23/3/20 22:26
A condition called CD3 delta SCID is caused by a mutation in the CD3D gene, which prevents the production of the CD3 delta protein that is needed for the normal development of T cells from blood stem cells. Researchers showed that a new genome editing technique called base editing can correct the mutation that causes CD3 delta SCID in blood stem cells and restore their ability to produce T cells....
Researchers uncover a protein deficiency in neurons of patients with neurodegenerative diseases that could be targeted by new gene therapy approach
- ScienceDaily
- 23/3/20 22:25
Researchers discovered that a protein called Stathmin-2 is lost in these neurons, which prevents them from regenerating after injury and disrupts their connection with the muscles to control movements.
Lack of canine COVID-19 data fuels persisting concerns over dog-human interactions
Early COVID-19 pandemic suspicions about dogs' resistance to the disease have given way to a long-haul clinical data gap as new variants of the virus have emerged.
After misconduct claims, star botanist has second paper retracted
Steven Newmaster, a prominent University of Guelph (UG) botanist and entrepreneur who has faced allegations of scientific misconduct, has had another paper retracted without his consent. Last week
the
Canadian Journal of Forest Research
pulled a study
in which Newmaster and colleagues said they used a genetic identification system known as DNA barcoding...
