Anguish, listening, resilience: Zweli Mkhize reflects on a year of Covid-19

Anguish, listening, resilience: Zweli Mkhize reflects on a year of Covid-19
On the anniversary of SA’s first case, the health minister looks back on how he’s coped with the pandemic
04 March 2021 - 20:17
It was a call to the president he hoped he would never have to make, but a year ago, Dr Zweli Mkhize had to do exactly that.
“I flew to Johannesburg the night before to address a black business meeting. On my way to the airport to fly to Cape Town, I got the call about the first confirmed Covid-19 case. I was rushing to parliament to respond to the debate about the country’s readiness for Covid-19. .. ....

Anti-hyperlipidemia drug improves brain connectivity in mouse models of schizophrenia

Anti-hyperlipidemia drug improves brain connectivity in mouse models of schizophrenia
New therapies that improve connectivity and circuitry in the brain of people with schizophrenia could result from the discovery by a RIKEN-led team of a potential new target for drugs to treat the psychiatric disorder
1.
Treatment for schizophrenia has not changed much in 60 years. Doctors still generally prescribe medicines designed to tame psychosis by blocking neurotransmitter signaling in the brain. While the drugs ease symptoms such as delusions and hallucinations, they leave many other aspects of the illness untreated and their side effects can be off-putting to many patients. Researchers are thus keen to find new targets for drugs. ....

Low-cost optical telescope developed for seeing distant galaxies

New Delhi
: Keeping in mind Prime Minister s call to develop technology in all spheres, Indian scientists have indigenously designed and developed a low-cost optical spectrograph. This can locate sources of faint light from distant quasars and galaxies in a very young universe, regions around supermassive black-holes around the galaxies, and cosmic explosions.
Its worthwhile noting that the spectrograph is about 2.5 times less costly compared to the imported ones and can locate sources of light with a photon-rate as low as about 1 photon per second. The cost of this instrument is nearly Rs 4 crore. The largest of its kind among the existing astronomical spectrographs in India, it has been successfully commissioned on the 3.6-m Devasthal Optical Telescope (DOT), located near Nainital, Uttarakhand. Interestingly, this spectrograph is not just the largest in the country but also Asia. ....

NIH scientists discover how DNA fragments can trigger inflammation in sickle cell disease

NIH scientists discover how DNA fragments can trigger inflammation in sickle cell disease

Researchers have discovered that DNA from the mitochondria - the cell’s “powerhouses” - acts as a danger signal in the body and triggers inflammation in people with sickle cell disease. A better understanding of mitochondrial DNA, long known to circulate in human blood, may provide vital insight into how to stop the underlying chronic inflammation that marks this inherited red blood cell disorder. It could also lead to new ways to reduce the pain crises suffered by people living with the life-threatening disease. ....

Researcher helps find largest supernova remnant by looking in right place
An international team of researchers, using powerful new X-ray telescope eROSITA to conduct the first all-sky X-ray survey in 25 years, have detected the largest supernova remnant ever discovered with X-rays, dubbed Hoinga.
