The star is only a little bit larger than Earth’s Moon, but more massive than the Sun and might be a Frankenstein zombie star.
Astronomers discovered the smallest and most massive white dwarf star, about the same size as Earth’s Moon with a mass greater than the Sun.
Swedish companies Volvo and SSAB have announced a collaboration to jointly explore the development of fossil-free, high quality steel for use in the automotive industry.

New research shows how the fundamental law of conservation of charge could break down near a black hole.
Singularities, such as those at the centre of black holes, where density becomes infinite, are often said to be places where physics ‘breaks down’. However, this doesn’t mean that ‘anything’ could happen, and physicists are interested in which laws could break down, and how.
Now, a research team from Imperial College London, the Cockcroft Institute and Lancaster University have proposed a way that singularities could violate the law of conservation of charge. Their theory is published in Annalen der Physik.
Wally Funk was one of 13 female aviators who lobbied for women to become astronauts in the early days of spaceflight.
Aviator Wally Funk wanted to be an astronaut in the earliest days of spaceflight. Sixty years later, on July 20, she’ll finally go to space with Blue Origin.
Funk was one of 13 female aviators later dubbed the Mercury 13 who, in 1961, passed all the exams necessary for admission to NASA’s astronaut corps and lobbied the federal government to send women into space. NASA and Congress demurred and women were excluded from becoming U.S. astronauts for more than a decade; Sally Ride became the first American woman to fly in space in 1983.
The United Arab Emirates’ (UAE) Hope Mars mission made its first major finding just a couple months after arriving at the Red Planet when it snagged unprecedented observations of a tricky aurora.
Antiaging gene therapies to overexpress TERT and Follistatin were used in a mouse model. The mice saw a 41 and 32% increase in median life span. The study also used a novel viral vector, cytomegalovirus for the delivery.
Liz Parish of Bioviva has treated herself with all of these antiaging gene therapies.
If humans experienced the same antiaging effect as the mice then humans would live to a median age of 100 with these treatments.
Researchers have created an unusual new alloy made up of not two, but five different metals, and put it to work as a catalyst. The new material is two-dimensional, and was able to convert carbon dioxide into carbon monoxide effectively, potentially helping to turn the greenhouse gas into fuels.
The new alloy belongs to a class of materials called transition metal dichalcogenides (TMDCs), which are, as the name suggests, made up of combinations of transition metals and chalcogens. Extremely thin films of TMDCs have recently shown promise in a range of electronic and optical devices, but researchers on the new study wondered if they could also be used as catalysts for chemical reactions.
The thinking goes that because reactions occur on the surface of a catalyst, materials with high surface areas will be more effective catalysts. And as sheets only a few atoms thick, TMDCs are almost nothing but surface area.
Preliminary results showed potent inhibition of both the Beta and Gamma variants by opaganib at non-cytotoxic doses, the company said.
Opaganib is a unique host-targeted, dual antiviral and anti-inflammatory drug that acts on the cause and effect of COVID-19.
