IN A NUTSHELL 🔭 Researchers using the James Webb Space Telescope discovered a pattern in galactic rotations. 🌀 Around 60% of ancient galaxies rotate clockwise, challenging previous assumptions of randomness. 🌌 The hypothesis suggests our universe might be within a massive black hole, redefining cosmic principles. 🔍 Observational bias, such as the Doppler effect, is considered an alternative explanation for …

Social media has been abuzz with users in Japan reporting sightings of a mysterious object that briefly lit up skies across the country’s west on Tuesday night as it fell. A Kyodo News livestream of a volcano on Sakurajima in Kagoshima Prefecture captured the moment at about 11:08 p.m. An official at the Japan weather agency’s Kagoshima meteorological office said …

A 1954 earthquake that rattled Northern California was likely caused by the infamous Cascadia Subduction Zone, a new study finds. The linking of the magnitude 6.5 quake with this particular seismic zone is important, because the Cascadia Subduction Zone, which stretches from northern California to Vancouver Island in Canada, is not known to give off many small or medium quakes. …

Chemical reagents The chemical reagents used in the synthesis experiments include tyrosine (C9H11NO3, 99.0 wt%, Sigma-Aldrich), histidine (C6H9N3O2, 99.0 wt%, Fluka), ciprofloxacin HCl(C17H18FN3O3 ⋅ HCl ⋅ H2O, Merck), n-hexane (C6H14, 97.0 wt%, Honeywell) and distilled water. All chemicals were used without further purification. Sample preparation and data collection Single crystals of ciprofloxacin hydrochloride were obtained through vapour diffusion of EtOH/MeCN. These crystals were then directly suspended by …

Scientists on Wednesday warned that abrupt and potentially irreversible changes are occurring in Antarctica. They said the changes, which are driven by climate change, could lead to “catastrophic consequences for generations.” The research was published in the journal Nature. It sought to describe the interlocking effects of global warming on the Antarctic, the frozen continent at the planet’s South Pole. The …

IN A NUTSHELL 🔭 Researchers using the James Webb Space Telescope discovered a pattern in galactic rotations, challenging previous beliefs. 🌀 Approximately 60% of ancient galaxies rotate clockwise, suggesting a potential cosmic order. 🌌 A hypothesis proposes that the universe might be within a black hole, altering our understanding of cosmology. 🔍 Alternative explanations include potential observational bias, highlighting the …

Protein expression and purification In Figs. 1–4 and 5d, we measured EYFP with the mutations S2insL/S65G/V68L/S72A/T203Y/H231L of avGFP, with an additional 6x His tag on the N-terminus (the full amino acid sequence is given at the end of this section). The protein was expressed using a pET vector constructed using HiFi assembly from Addgene plasmids 78466 and 29653. The resulting vector …
