"NASA's Rare Repair Spacewalk: Fixing Busted Telescope"

NASA is planning a rare spacewalk to repair a telescope mounted on the International Space Station that has been affected by unwanted sunlight leaking into its sensitive detectors. The repair involves installing patches to block out the sunlight, and the astronauts will carry out the repair during an upcoming mission. This challenging repair task is necessary to ensure the telescope's normal operations and measurements are not affected by the light leak.

"Astronauts to Conduct Rare Repair Spacewalk on Leaky ISS Telescope"

NASA plans to send astronauts to repair the Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station (ISS) due to a "light leak" issue affecting its X-ray measurements. The telescope, launched in 2017, was not designed for servicing, presenting a challenge for the repair. This will be the fourth science observatory that NASA has risked astronauts to repair, highlighting the risks and rewards of having astronauts fix equipment not originally intended for servicing in space.

"NASA Telescopes Uncover Clues to Mysterious Radio Bursts"

NASA's NICER and NuSTAR telescopes observed a fast radio burst from the magnetar SGR 1935+2154, providing valuable data on the phenomenon. The burst occurred between two periods of rapid rotational rate increase, followed by a surprising rapid decrease. The increase in high-energy light before the burst led to the telescopes' orientation towards the magnetar. Scientists believe the burst was caused by material eruption from the magnetar's interior, but the exact mechanism behind fast radio bursts remains uncertain. The findings were published in the journal Nature, shedding light on the nature of these mysterious cosmic events.

"NICER: Revolutionizing Gene Editing with Enhanced Safety"

Researchers in Japan have developed a new gene editing technique called NICER, which is as effective as CRISPR/Cas9 but significantly reduces unintended DNA mutations. NICER uses an enzyme called a nickase to create multiple small cuts in single DNA strands, promoting interhomolog homologous recombination to correct heterozygous mutations. The technique has shown promising results in restoring gene expression in cells derived from genetic diseases involving compound heterozygous mutations. NICER represents a safer alternative to conventional CRISPR/Cas9 methods for the treatment of genetic diseases.

Enhancing Genome Editing with the NICER Method

Researchers in Japan have developed a new gene editing technique called NICER, which significantly reduces unintended DNA mutations compared to the conventional CRISPR/Cas9 method. NICER involves creating multiple small cuts in single DNA strands using an enzyme called a nickase, which induces single-strand breaks that are typically repaired without causing mutations. The technique has shown promising results in correcting heterozygous mutations in cells and restoring the expression of disease-causing genes. NICER may provide a safer alternative for treating genetic diseases caused by mutations.
