//Although lipomatosis is very common and increases with age, scientists have previously devoted little discussion and research to it. Scientists at Uppsala University have just published a study that offers significant insights into the causes of human lymph node function decline with aging and the effects on immune system performance.

Scientists carefully examined more than 200 lymph nodes to show that lipomatosis starts in the medulla, which is the center of the lymph node. They also provided evidence connecting lipomatosis to converting lymph node supporting cells (fibroblasts) into adipocytes (fat cells). They also demonstrate that fibroblast subtypes in the medulla are more likely to develop into adipocytes.\.

The study is a first step toward understanding why lipomatosis occur.

Kepler-1658b’s orbit is getting a little shorter — and therefore a little closer to the blazing surface of its star — every year.

Finding doomed planets is slow, painstaking work. It took thirteen years of close observation — first with Kepler and some of the most powerful telescopes here on Earth, and then with NASA’s Transiting Exoplanet Survey Satellite (TESS), which launched in 2018 — to notice the slow shrinking of Kepler-1658b’s orbit. Recognizing the signs of deadly orbital decay in other exoplanets is going to take a similar amount of time and a similar volume of data, but Vissapragada and his colleagues say they’re getting there.

“We should begin to see hints of orbital decay for these planets within the next decade,” he and his colleagues write in their recent paper.

Turning astrophysical data into audio has led to all sorts of surprising discoveries, from micrometeoroids bombarding spacecraft to lightning on Saturn. Now, there is a push to get more astronomers to use sonification.

The Internet and COVID pandemic combined have driven both online gaming and gambling development for the good and the bad.

The site works like OpenAI’s ChatGPT, which went viral earlier this year for its unique and realistic responses from a computer program. But be careful about its answers.

Framing the process of ageing more as a treatable condition, rather than an inevitable consequence of life, could allow people to live longer, thanks to emerging biotechnologies and a greater emphasis on healthy living.
