NASA’s Artemis megarocket suffered another huge delay the week of May 4–10, as scientists revealed a new target for cancer treatments and startling news about global bird populations.
Here are the biggest science stories of the week, told in 8 stunning images.
Researchers discovered that chromosomes can be trapped in a cell’s membrane when it divides, which can lead to cancer in the resulting cells. The finding could lead to new cancer prevention methods.
Researchers determined good macrophage diversity is one reason why some people are more resistant to Covid-19. An overabundance of pro-inflammatory macrophages could lead to a more dangerous response to the infection. The finding could help develop more effective drug treatments.
Astronomers found a binary companion star in the aftermath of its partner star’s supernova. It’s the first observation of its kind involving a supernova that was stripped of its gas envelope before exploding. The finding supports the theory that a star can siphon hydrogen from its companion before a supernova.
Scientists reported an estimated 48 percent of bird species worldwide are declining in population. They warn of a wave of extinctions if conservation efforts aren’t directed at preserving avian habitats.
Scientists revealed a fossil revealing Olenoides serratus trilobites may have used clasper limbs to assist in mating, much like modern horseshoe crabs. Fossils rarely expose mating behavior, and the finding was only possible because the trilobite was missing part of its exoskeleton, revealing the claspers beneath.
After the latest SLS wet dress rehearsal was delayed to June, NASA announced in a teleconference that the Artemis I mission likely won’t fly until August at the earliest. Previous plans aimed for a launch of the Moon-bound megarocket as early as April.
In a proof-of-concept study, scientists created neurons from stem cells that can function in the brain just like other neurons. It could pave the way to treat neuron damage caused by Parkinson’s disease.
Researchers found algae and prokaryote cells embedded in an 830-million-year-old sample of halite. The study used non-destructive methods of examining the cells, and may offer another way to search for evidence of ancient extraterrestrial life.
