For the past thirty years, the star β Pictoris has fascinated astronomers because it enables them to observe a planetary system in the process of formation. It is made up of at least two young planets, and also contains comets, which were detected as early as 1987. These were the first comets ever observed around a star other than the Sun.

Now, an international research team headed by Alain Lecavelier des Etangs, CNRS researcher at the Institut d’Astrophysique de Paris (CNRS/Sorbonne Université)1, has discovered 30 such exocomets and determined the size of their nuclei1, which vary between 3 and 14 kilometres in diameter...

Research findings may help identify drug targets for neuromuscular disorders. Using genetic approaches, researchers have demonstrated how a certain protein is involved in skeletal muscle growth. The findings open new avenues to develop drug targets for neuromuscular diseases and other pathological conditions.

In the gym, you are not just pumping iron, you are oxygenating muscle cells which keeps those muscles healthy, strong and growing — a process called hypertrophy, or an increase in muscle mass due to an increase in muscle cell size. Conversely, under the covers, lounging, your muscles may begin to atrophy, or shrink.

A camera usually requires a lens system to capture a focused image, and the lensed camera has been the dominant imaging solution for centuries...

Hydrogen and oxygen ions escaping from Earth’s upper atmosphere and combining on the moon could be one of the sources of the known lunar water and ice, according to new research by University of Alaska Fairbanks Geophysical Institute scientists.

The work led by UAF Geophysical Institute associate research professor Gunther Kletetschka adds to a growing body of research about water at the moon’s north and south poles.

Finding water is key to NASA’s Artemis project, the planned long-term human presence o...
