Researchers believe they have discovered a new biological mechanism for obesity, pointing to rare variants on two genes that dramatically increase the risk of carrying excess weight.

The drug, which is in the same family as blockbuster weight-loss drugs such as Wegovy, slowed development of symptoms by a small but statistically significant amount.

Lab-grown meat, cultivated meat, cell-based meat, slaughter-free meat: All of these terms refer to the process of creating real meat from animal cells, despite names that may allude to a vegan product.
What benefits are there to growing meat from chicken cells rather than raising animals for slaughter? Industrial animal agriculture is responsible for an estimated 15 percent of total global greenhouse gas emissions, and with demand for meat projected to double in the next decade, this technology could offer a more sustainable option.
Come with us as we step inside a lab-grown meat facility, and become some of the first to taste-test chicken that was grown in a bioreactor instead of on a factory farm.

A supersonic drone that will be propelled by a revolutionary new engine has taken to the skies for the first time. When Venus Aerospace’s aircraft does go supersonic on a later date, it will be powered by a Rotating Detonation Rocket Engine (RDRE).
Supersonic drones may sound like something bleeding edge, but they’re surprisingly old hat as a basic concept. As far back as the early 1950s, the US Air Force was fielding remote-controlled supersonic jets for targets to test air defenses, as platforms for reconnaissance in dangerous areas, or as weapons armed with conventional or nuclear warheads.
However, the one thing they’ve all had in common over the past 75 years was a jet engine for propulsion to boost them past Mach 1. In recent years, advances in avionics, aerodynamics, and autonomous systems have allowed uncrewed aircraft to expand their roles, but at their heart, they were still jet propelled.
Researchers at Tel Aviv University have developed a new treatment course for patients with metastasizing breast cancer, using medication already on the market.
Based on tissue samples from American and Israeli patients and using an animal model, the researchers from the Faculty of Medical and Health Sciences showed that a combination of existing drugs can hinder the spread of cancer to the bones, thereby improving the chances of survival.
More than 75 percent of patients with metastatic breast cancer see it spread to the bone.
The first patient to receive a kidney transplanted from a genetically modified pig has fared so well that he was discharged from the hospital on Wednesday, just two weeks after the groundbreaking surgery.
The transplant and its encouraging outcome represent a remarkable moment in medicine, scientists say, possibly heralding an era of cross-species organ transplantation.
Two previous organ transplants from genetically modified pigs failed. Both patients received hearts, and both died a few weeks later. In one patient, there were signs that the immune system had rejected the organ, a constant risk.
Study reviews the advancements in pharmacological treatments for neuropsychiatric syndromes in neurodegenerative disorders, discussing the complexities of managing symptoms such as depression, disinhibition, apathy, psychosis, and agitation to improve patient care.
Summary: Researchers unveiled a novel approach to combat Alzheimer’s disease by activating microglia, the brain’s immune cells, to devour amyloid beta plaques, a hallmark of the condition. This study highlights the potential of using immunotherapy to not only tackle Alzheimer’s but also other neurodegenerative diseases characterized by harmful protein accumulations.
The team’s method involves using an antibody to stimulate microglia into clearing these plaques, offering a promising alternative to current treatments that directly target amyloid beta and might cause side effects like ARIA. This breakthrough paves the way for new therapeutic strategies that harness the immune system to fight the devastating effects of Alzheimer’s and possibly other diseases like Parkinson’s and ALS.
Can Data be Stored in DNA?

Analyzing and storing large amounts of data requires a lot of energy, so the future of technology might hold a different approach to data storage. At least, that is what Professor Søren Brunak from the University of Copenhagen thinks.
Brunak states that while Denmark is one of the best in the world at health data, analyzing and storing huge amounts of health data comes at a climate cost. “We have begun to consider the carbon footprint of bioinformatics and CO2 emissions resulting from data analysis,” he adds.
With rates rising around the world, public-health leaders must prioritize prevention, treatment, funding and data.
