This newly revised NASA Hubble Space Telescope image of the Hickson Compact Group 31 (HCG 31) of galaxies highlights streams of star-formation as four dwarf galaxies interact. The bright, distorted clump of young blue-white stars (top-right of center) is NGC 1741. Although it appears to be a single galaxy, NGC 1741 is actually a pair of colliding dwarf galaxies. Another dwarf, cigar-shaped galaxy...
In the Temple of Khnum at Esna, Upper Egypt, German and Egyptian researchers have uncovered a series of vibrantly-colored ceiling frescoes. The relief images in the central section of the ceiling, Professor Christian Leitz from the University of Tübingen reports, make up a total of 46 depictions of the Upper-Egyptian vulture goddess Nekhbet and the Lower-Egyptian serpent goddess Wadjet. Both are...
Vibrant coral reefs teeming with marine life are diminishing throughout the Caribbean as global temperatures rise. Coral reefs are habitats that support the seafood industry, are barriers for coastal communities from storms, flooding and sea level rise, and are attractions for tourism. Their net economic value worldwide is estimated to be tens of billions of dollars. However, if atmospheric and...

Researchers who jumped into the field from distant disciplines published lower impact work, study finds
The House Intelligence Committee’s Counterterrorism, Counterintelligence, and Counterproliferation subcommittee would like to make one thing very clear: They did not spend 90 minutes this morning conducting public hearings into the existence of UFOs. Yes, they were discussing unidentified objects, and yes those objects were seen to be flying, but the term for them today is...
Early animals formed complex ecological communities more than 550 million years ago, setting the evolutionary stage for the Cambrian explosion, according to a new study.
A comparison of four COVID-19 vaccinations shows that messenger RNA (mRNA) vaccines -- Pfizer-BioNTech and Moderna -- perform better against the World Health Organization's variants of concern (VOCs) than viral vector vaccines -- AstraZeneca and J&J/Janssen. Although they all effectively prevent severe disease by VOCs, the research suggests that people receiving a viral vector vaccine are more...
Different types of brain damage caused by a concussion may lead to similar symptoms in children, according to new research. A new way of studying concussions could help develop future treatments.
Researchers have discovered that Type I interferon (IFN) plays a key role in helping the immune system effectively target viruses, while stopping white blood cells from 'going rogue' and attacking the body's own organs. This opens the way to potential new treatments that can save many lives.
Older breast cancer survivors with cardiometabolic risk factors who restricted food intake to eight hours during the weekday, followed by 16 hours of fasting, lowered their risk of cardiovascular disease (CVD) after a few weeks, according to a new research letter.
The waters rose overnight and by morning formed a shallow pond over the grassy field covering a cemetery in Jamestown, one of the founding sites of the American nation.
X-ray detection is of great importance in diverse applications, such as radiation detection, medical diagnosis, and security inspection. A popular way to achieve X-ray detection is to integrate a photodetector with a luminescent material called a scintillator, which emits energy in the form of light. Scintillators can convert high-energy X-ray photons to low-energy visible luminescence.
Researchers have developed a new metasurface-based device that can produce multiple distinct holographic images depending on the surrounding medium and the wavelength of light used. The ability to store information that is only retrievable with the right set of keys—such as a certain light wavelength combined with wet conditions—could be further developed to design simple yet effective...
