This collection of 19 face-on spiral galaxies from the James Webb Space Telescope in near- and mid-infrared light is at once overwhelming and awe-inspiring. “Webb’s new images are extraordinary,” said Janice Lee, a project scientist for strategic initiatives at the Space Telescope Science Institute in Baltimore, Maryland. “They’re mind-blowing even for researchers who have studied these same galaxies for decades. Bubbles and filaments are resolved down to the smallest scales ever observed, and tell a story about the star…

The EnVision mission to Venus will explore why Earth’s closest neighbor is so different. Credit: NASA / JAXA / ISAS / DARTS / Damia Bouic / VR2PlanetsESA’s EnVision mission to Venus, set for a 2031 launch, aims to explore the planet’s geology, climate, and internal structure. This comprehensive study seeks to answer key questions about Venus’s evolution and current state.ESA’s next mission to Venus was officially ‘adopted’ on January 25 by the Agency’s Science Programme Committee. EnVision will study Venus from its inner…

Caves and rock shelters dot the mountains in the northwestern highlands of Thailand. Over 40 in Mae Hong Son province contain wooden coffins on stilts, dating back 1,000–2,300 years. Credit: Selina Carlhoff Deciduous and evergreen forests dominate the limestone karst formations of the northwestern highlands of Thailand. A vast number of caves and rock shelters intersperse the mountains. …

In case you missed the latest podcast episode of Search Off the Record, Google’s Gary Ilyes stirred up some controversy when he made a comment about HTML structure not mattering much for SEO.He later clarified on Linkedin that “not mattering much” doesn’t mean “doesn’t matter at all.” Still, that didn’t stop any of the SEO controversy. Being unable to avoid controversy, I couldn’t help but jump in – in an attempt to clarify a few common points and misconceptions I keep seeing pop up.So, does HTML structure matter…

The Karnataka government has issued a uniform fare structure for aggregator-operated cabs in addition to city taxis. Under the new structure, operators such as Uber, Ola and Rapido will only be able to charge distance-based fares depending on the cost of the vehicle. The state government has thus eliminated different fares for cabs deployed by ride-hailing platforms and city taxis. While city taxis typically follow a fare chart or metered fares, ride-hailing platforms show an upfront fare while booking.Elevate Your Tech…

The p38a protein is a key enzyme involved in regulating various cellular functions and has been linked to the progression of several diseases, including cancer, chronic inflammation, and neurodegenerative disorders. Its role in these diseases is often associated with its ability to control cell growth, death, and response to stress. The recent discovery of its oxidized form, which alters its functional state, provides a deeper understanding of its mechanisms in disease and could lead to more effective treatments targeting…

A colossal structure in the distant Universe is defying our understanding of how the Universe evolved.In light that has traveled for 6.9 billion years to reach us, astronomers have found a giant, almost perfect ring of galaxies, some 1.3 billion light-years in diameter. It doesn't match any known structure or formation mechanism.The Big Ring, as the structure has been named, could mean that we need to amend the standard model of cosmology.The discovery, led by astronomer Alexia Lopez of the University of Central…

Astronomers have discovered a colossal cosmic structure that’s so big it threatens to undermine our entire understanding of the universe. The Big Ring spans about 3% of the radius of the entire observable universe – and it itself might be part of an ever bigger structure.The Big Ring – a name that’s a hell of an understatement – is an almost perfectly circular group of galaxies and galaxy clusters with a diameter of about 1.3 billion light-years, and a circumference of around 4 billion light-years. If it was visible with…

It's estimated around 3% of people in the UK experience long COVID – persistent, long-lasting symptoms after a COVID-19 infection.Long COVID encompasses a range of health problems that can begin after even a mild COVID infection. Some of these symptoms include extreme fatigue, shortness of breath, muscle aches and loss of smell.For around 50% of long COVID sufferers, their symptoms also fit criteria for a diagnosis of myalgic encephalomyelitis (ME), a neuro-immune disease characterised by depleted energy, muscle weakness…

The James Webb Space Telescope has revealed a new structure within the Beta Pictoris system, resembling a cat’s tail. This discovery, led by Isabel Rebollido, indicates complex interactions within the system’s debris disks and suggests recent dust production events, expanding our understanding of planetary system dynamics.
