NASA’s James Webb Space Telescope and the Keck Observatory in Hawaii have together captured Saturn’s largest moon Titan in near-infrared.

The new images reveal clouds in the northern hemisphere near Kraken Mare, the largest known methane sea on the giant moon’s surface. Titan is the only other body in the solar system that has rivers, lakes and seas, though instead of water they flow with liquid methane and ethane. These hydrocarbons—as well as water and ammonia—also produce clouds and rain on the giant moon.

JWST’s image—from November 4, 2022 and published for the first time this week—revealed two clouds in the atmosphere, so scientists then pointed the largest optical telescope on Earth, the Keck Telescope, at Titan just 30 hours later to confirm their presence.

Gravity could be a leading cause of irritable bowel syndrome, along with increased serotonin levels and changes in the gut microbiome.

Approximately 20 to 40 percent of all visits to gastroenterologists are due to irritable bowel syndrome (IBS) symptoms. The common disorder affects between 25 and 45 million people in the United States and up to ten percent of the world’s population, yet experts aren’t sure of how or why it develops.

However, there is no dearth of theories. While one explains that IBS is a gut-brain disorder, another theory states that IBS is caused by abnormalities in the gut microbiome.

The Federal Communications Commission issued a key authorization to Elon Musk’s SpaceX on Thursday to launch up to 7,500 next-generation satellites in its Starlink internet network.

“Specifically, we grant SpaceX authority to construct, deploy, and operate up to 7,500 satellites operating at altitudes of 525,530, and 535 km and inclinations of 53, 43, and 33 degrees, respectively, using frequencies in the Ku-and Ka-band. We defer consideration of SpaceX’s proposed use of E-band frequencies and tracking beacons,” said the order.

The presence of food-specific IgA antibodies in the gut does not prevent peanut or egg allergies from developing in children, according to a Northwestern Medicine study published in Science Translational Medicine.

Scientists examined from more than 500 infants across the country and found that the presence of Immunoglobulin A, the most common antibody found in in the , does not prevent peanut or from developing later in life.

This discovery calls into question the role of Immunoglobulin A, or IgA, which was previously thought to be a protective factor against the development of food allergies.

A gene linked to autism spectrum disorders plays a critical role in early brain development and may shape the formation of both normal and atypical nerve connections in the brain, according to a new study by Weill Cornell Medicine investigators.

The study, published Nov. 28 in Neuron, employed a combination of sophisticated genetic experiments in mice and analysis of human brain imaging data to better understand why mutations in a gene called Gabrb3 are linked to a high risk of developing (ASD) and a related condition called Angelman Syndrome. Both conditions involve abnormal behaviors and unusual responses to sensory stimuli, which appear to stem, at least in part, from the formation of atypical connections between neurons in the brain.

“Neuron al connections in the brain, and developmental synchronization of neuronal networks, are perturbed in individuals with , and there are that are implicated in the pathogenesis of ASD,” said co-first author Dr. Rachel Babij, a former student in the Weill Cornell/Rockefeller/Sloan Kettering Tri-Institutional MD-Ph. D. program in the laboratory of Natalia De Marco García, an associate professor in the Feil Family Brain and Mind Research Institute at Weill Cornell Medicine.

One of the world’s leading hospitals is preparing to offer longevity clinical services to patients. Sheba Medical Center in Tel Aviv, Israel, is poised to open a dedicated longevity centre in 2023, with the goal of democratising the extension of healthy lifespan for the masses.

Longevity. Technology: While research, development and investment in longevity are at an all-time high, the implementation of longevity clinical practice in mainstream healthcare is virtually non-existent. While private clinical practices are now making longevity services accessible to those who can afford it, the societal benefit of improving healthspan can only be realised if everyone can access it. To learn more, we caught up with Professor Tzipi Strauss, Director of Neonatology at Sheba Hospital, who is the driving force behind the new centre.

It may seem curious that a paediatrician is the instigator of an initiative focused on improving aging, but Strauss explains that the relevance of longevity begins at birth.
