Scientists have created a synthetic human antibody that can effectively neutralize a dangerous toxin produced by various snake species. This breakthrough study, published in the journal Science Translational Medicine, utilized a method previously used to identify antibodies for HIV and COVID-19, allowing for the creation of this new venom-neutralizing antibody.
A defunct Earth-observing satellite descended from orbit Wednesday and safely disintegrated over the Pacific. The European Remote Sensing 2 satellite, known as ERS-2, made its reentry halfway between Hawaii and Alaska. The European Space Agency confirmed the end of the 5,000-pound (2,300-kilogram) spacecraft. There were no reports of damage or injuries.
Deep brain stimulation (DBS) shows promise in treating depression that resists other treatments. Researchers are studying the effectiveness of tailored DBS treatments, and the Food and Drug Administration is reviewing Abbott Laboratories' request to use DBS devices for treatment-resistant depression.
An international team of scientists, led by researchers from Inter-University Centre for Astronomy and Astrophysics (IUCCA), used Astrosat to study the black hole X-ray binary system MAXI J1820+070. The study provides insights into the system's behavior, accretion states, black hole's spin, and its connection with emissions from inner and outer accretion flow components.
Researchers at the University of Illinois Urbana-Champaign have developed a sustainable approach for 3D-printing dynamic colors from a single ink, inspired by chameleons' color-changing abilities. By modulating structural color using UV-assisted direct-ink-write 3D printing, they can create color gradients in the visible wavelength spectrum without the need for multiple paints.
Researchers used human retinas to study how an offshoot of vitamin A produces specialised cells for seeing colours. The discovery of the role of retinoic acid in the development of cone cells has implications for understanding colour blindness and age-related vision loss. (40 words)
Tagrisso from AstraZeneca has shown positive results in a trial for advanced non-small cell lung cancer patients with a specific genetic mutation. It slowed disease progression and could be the first targeted treatment option for stage 3 patients. AstraZeneca said the trial showed a statistically significant and highly clinically meaningful improvement in progression-free survival for patients whose cancer was unable to be removed by surgery and had responded to initial chemoradiation.
The Geosynchronous Satellite Launch Vehicle-II (GSLV-II) of ISRO has gained a positive reputation after two consecutive successful launches. It has been praised for its maturity, obedience, and discipline. The GSLV-II is now considered a robust vehicle for ISRO, similar to the PSLV.
A recent study published in the journal Palaeontology reveals that the 280-million-year-old fossil Tridentinosaurus antiquus, previously believed to be a significant specimen for understanding the evolution of early reptiles, may have been partly forged, suggests a study. The fossil, found in the Italian Alps in 1931, was initially thought to belong to the reptile group Protorosauria.
Japan's space agency announced the successful launch of its new flagship rocket on Saturday, making it third time lucky for the H3 after years of delays and two previous failed attempts. The H3 rocket, billed as flexible and cost-effective by space agency JAXA, "was put into orbit," a JAXA official told AFP.
Ancient viruses that infected vertebrates hundreds of millions of years ago played a pivotal role in the evolution of our advanced brains and large bodies, a study said Thursday. This led them to believe the sequence appeared in the tree of life around the same time as jaws, which first evolved around 360 million years ago in the Devonian period, called the Age of Fishes.
