Astronomers have gained insights into star formation by capturing the first spatially resolved detection of protostellar outflows and jets in the Milky Way's outer region.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have made the highest resolution image to date, revealing new insights into the unusual and mysterious architecture of the debris disk encircling Fomalhaut, one of the brightest and most well-studied stars in our cosmic neighborhood.

The cause of death for two baby pterosaurs has been revealed by University of Leicester paleontologists in a post-mortem 150 million years in the making.

The Atlantic Meridional Overturning Circulation (AMOC) is an enormous loop of ocean current in the Atlantic Ocean that carries warmer waters north and colder waters south, helping to regulate the climate in many regions. The collapse of this critical circulation system has the potential to cause drastic global and regional climate impacts, like droughts and colder winters, especially in Northwestern Europe.

In 2023, the Amazon rainforest experienced its worst recorded drought since records began. River levels dropped dramatically and vegetation at all levels deteriorated due to intense heat and water shortages. In such conditions, plants release increased amounts of monoterpenes—small, volatile organic compounds that act as a defense mechanism and help communication with their environment. Some molecules, such as α-pinene, which smells like pine, occur as mirror-image pairs, known as enantiomers.

Investigators at Johns Hopkins Medicine report new evidence that the protein Piezo1 controls skin growth by detecting when skin is stretched and then coordinating the metabolic and immune changes necessary for growth. Experts say the findings could ultimately help doctors develop noninvasive therapeutic approaches to create new skin for treating burns and other injuries that require a skin graft.

Organ donors can save lives, for example, those of patients with kidney failure. Unfortunately, there are too few donors, and the waiting lists are long. 3D bioprinting of (parts of) organs may offer a solution to this shortage in the future. But printing living tissues, bioprinting, is extremely complex and challenging.

Temperatures in the Mediterranean are currently rising to record levels. Instead of a refreshing dip, holidaymakers in places like Greece, Italy, and Spain, among other places, are now facing water temperatures up to 28° C or even higher. With an average water temperature of 26.9° C, July 2025 was the warmest since records began for the Mediterranean Sea, according to the Copernicus Earth Observation Service.

Now, at the end of the summer, when the thrush nightingales leave Europe for southern Africa, they do not fly at full speed. Instead, they maintain an even pace—and according to a new study in Current Biology from Lund University, this is no coincidence.

A research team led by Ph.D. candidate Wang Haozhi under the supervision of Prof. Ali Esamdin at the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences (CAS) has revealed the genuine source of the pulsating star KOI-1755 transit signal using the Kepler space telescope. Their findings are published in The Astronomical Journal.
