In a new study, Yale researchers offer insight into leptin, a hormone that plays a key role in appetite, overeating, and obesity. Their findings advance knowledge about leptin and weight gain, and also suggest a potential strategy for developing future weight-loss treatments, they said.

The study, led by investigators at Yale and Harvard, was published the week of June 17, 2019, in the Proceedings of the National Academy of Sciences.

Leptin, which is secreted by fat cells, informs the brain when fuel stored in body fat and in the liver is becoming depleted. It has not been well understood how low leptin concentrations in plasma — the largest component of blood — increase appetite. The researchers studied the biology of leptin in rodents. They also investigated the influence of nerve cells in the brain known as AgRP neurons, which regulate eating behavior.

Amazon and Blue Origin founder Jeff Bezos gave more insight into his space company’s lunar plans on Wednesday, explaining how its spacecraft will eventually be powered with fuel harvested from the moon.

“We know things about the moon now we didn’t know about during the Apollo days,” Bezos said, speaking at the JFK Space Summit in Boston, Massachusetts.

One of the things learned since Apollo that Bezos highlighted is that there are deposits of water ice at the bottom of craters on the moon.

What causes the immune system, designed to protect us, to turn on the body and attack healthy cells? Common bacteria that reside in the human gut may be partly to blame, say Yale researchers, who studied the origins of a serious autoimmune disease that frequently affects young women.

For their study, the research team focused on cells from patients with antiphospholipid syndrome, an disorder that raises the risk of blood clots. This chronic condition can lead to lung clots, strokes, heart attacks, and in pregnant women, miscarriages or still births.

Using patient immune cells and antibodies, as well as animal models of the disease, the investigators did several experiments to explore the phenomenon. They found that a , Roseburia intestinalis, can trigger the disease in individuals who have a genetic predisposition. In those patients, the immune system’s defender T and B cells react to a blood protein involved in clotting, and also to the bacteria, in certain found in the bacteria. Over time, this ongoing “cross-reactive” response leads to tissue damage and chronic disease.

Physicists have discovered a novel kind of nanotube that generates current in the presence of light. Devices such as optical sensors and infrared imaging chips are likely applications, which could be useful in fields such as automated transport and astronomy. In future, if the effect can be magnified and the technology scaled up, it could lead to high-efficiency solar power devices.
