Difficulty swallowing (dysphagia) affects your quality of life and your health. The ability to safely swallow is vital for adequate nutrition and hydration, and it prevents foods and liquids from entering your lungs, where they can cause pneumonia.
Can the fountain of youth come in the form a pill?
Imagine this: a cocktail of specialized chemicals that rejuvenates your whole body, from your eyes and brain to your kidneys and muscles—bringing you back to a more youthful version of yourself.
Sound like science fiction?
Giant waves have been found swirling in the plasma at the boundary of Jupiter’s magnetosphere, scientists have found.
Data from Juno suggests the Jupiter probe regularly dips through these waves, invisible to the naked eye, as it orbits the giant planet. The discovery helps astronomers understand how mass and energy is transferred from the solar wind to the Jovian planetary environment.
Actually, such waves are not unknown in the Solar System. They’re known as Kelvin-Helmhotz waves, and they occur when there’s a difference in velocity at the boundary between two fluids. They can commonly be seen where wind blows across the surface of lakes and oceans, between currents in water, or even among bands of clouds in a planet’s atmosphere.
Powerful tech companies keep LLMs like GPT-4 shrouded in secrecy. But a new wave of open-source LLMs is giving the power of chatbots to the people.
The world’s largest community of 3D-printed homes is being built in Texas — and the neighborhood just unveiled its first completed house.
With walls “printed” using a concrete-based material, the single-story structure is the first of 100 such homes set to welcome residents starting September.
The community is part of a wider development in Georgetown, Texas called Wolf Ranch. It’s located about 30 miles north of Austin, the state capital, and is a collaboration between Texas construction firm ICON, homebuilding company Lennar and Danish architecture practice Bjarke Ingels Group (BIG).
The half-dozen creatures, a type of nematode or roundworm, were last awake when Neanderthals and woolly mammoths roamed the Earth.

By donating these healthy corneas to individuals afflicted with corneal diseases, which are among the most common causes of vision loss, patients can benefit from improved vision and potentially regain their sight.
More often than not, studies of human biology are conducted when the body is under duress from infection or disease. Now, as part of a larger effort to delineate what “healthy” looks like, two Stanford Medicine teams have unfurled detailed molecular maps of healthy human intestinal and placental tissues. The maps, which capture cell types, cell quantity and other cellular nuances, are just two of a collection of maps that will establish a cellular baseline for the majority of the human body, including where cells in certain tissues congregate, how tissues develop during pregnancy and how cell-to-cell interactions drive human biology.
The studies, which published in Nature on July 19, are part of a larger effort spearheaded by the Human Biomolecular Atlas Program — called HuBMAP — funded by the National Institutes of Health. It aims to fill gaps in our knowledge of how the human body works when it’s in tip-top shape. Dozens of teams from the United States and Europe contribute to the HuBMAP consortium.
“In research, we have a habit of studying things that are abnormal without really understanding what normal looks like,” said Michael Angelo, MD, PhD, an assistant professor of pathology who is also the co-chair of the HuBMAP steering committee. “That’s created a big gap in our knowledge. HuBMAP is the only effort that is systematically focusing on the spatial architecture of these tissues.”
