Adaptability of some coral reef fish to rising temperatures

Researchers have found that reef fish from the Arabian Gulf, the world's hottest sea, exhibit a higher tolerance to temperature fluctuations compared to those from more thermally stable coral reefs. However, the Arabian Gulf hosts fewer fish species overall, indicating that only certain fishes can withstand rising global temperatures.

Origin and diversity of Hun Empire populations

A multidisciplinary and international research project has brought fresh insights into the origins and diversity of the populations that lived under and after the Hun empire between the late 4th and 6th century CE in Central Europe. Combining forefront archaeogenomic analyses with archaeological and historical investigation, the study connects some of the European Hun-period individuals directly to some high-status elite of the earlier Xiongnu Empire -- a powerful nomadic empire centered in the Mongolian steppe centuries before the Huns emerged north and west of the Black Sea. It also shows that only few Hun-period individuals carried East-Asian ancestry, and that the newcomers of the Hun period were of rather mixed origin. Thus, it sheds light on the much-discussed population dynamics that shaped Eurasian history during Late Antiquity.

Evolution is traditionally associated with a process of increasing complexity and gaining new genes.

Thawing permafrost threatens up to three million people in Arctic regions

In an interdisciplinary and transdisciplinary study, an international team examined the social risks for Arctic regions associated with thawing permafrost. They identified five key risks related to infrastructure, transport and supply, water quality, food security and health. The scientists found that the thawing permafrost posed an increased risk of exposure to infectious diseases and release of contaminants, and interruptions of supply routes.

Conquest of Asia and Europe by snow leopards during the last Ice Ages uncovered

Scientists have identified fossils of snow leopards. The discovery has allowed them to trace the evolutionary history of the species during the Quaternary period and to propose how it dispersed from the Tibetan plateau to the Iberian Peninsula, far from the high and icy Himalayan mountains.

This metaphorical cat is both dead and alive -- and it will help quantum engineers detect computing errors

Engineers have demonstrated a well-known quantum thought experiment in the real world. Their findings deliver a new and more robust way to perform quantum computations and they have important implications for error correction, one of the biggest obstacles standing between them and a working quantum computer.

Floating solar panels could support US energy goals

Federal reservoirs could help meet the country's solar energy needs, according to a new study. Geospatial scientists and senior legal and regulatory analyst quantified exactly how much energy could be generated from floating solar panel projects installed on federally owned or regulated reservoirs.

Residents of unburned homes reported health symptoms months after Marshall Fire

Wildfires that burn homes and vehicles could expose people to dangerous airborne compounds through ash and smoke. Research has shown that people returning to their unburned homes may also experience health symptoms months after a nearby fire is extinguished. Through a survey of people affected by the 2021 Marshall Fire in Boulder, Colorado, researchers found that headaches, sore throats and coughs were frequently self-reported by residents living near burned structures.

Synthetic chemicals and chemical products require a new regulatory and legal approach to safeguard children's health

Nations must better safeguard health and reduce childhood diseases linked to exposures to toxic chemicals, according to researchers. Governments need to test and regulate chemicals and chemical products as closely as they safeguard prescription drugs, the researchers write.

DNA nanorobots can alter artificial cells

Scientists have succeeded in controlling the structure and function of biological membranes with the help of 'DNA origami'. The system they developed may facilitate the transportation of large therapeutic loads into cells. This opens up a new way for the targeted administration of medication and other therapeutic interventions. Thus, a very valuable instrument can be added to the toolbox of synthetic biology.

X-ray flashes from a nearby supermassive black hole accelerate mysteriously

Astronomers observed flashes of X-rays coming from a supermassive black hole at a steadily increasing clip. The source could be the core of a dead star that's teetering at the black hole's edge.

Pluto-Charon formation scenario mimics Earth-Moon system

A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size of the main body, unlike other moons in the solar system. The scenario also could support Pluto's active geology and possible subsurface ocean, despite its location at the frozen edge of the solar system.

Oldest-known evolutionary 'arms race'

A new study presents what is believed to be the oldest known example in the fossil record of an evolutionary arms race. These 517-million-year-old predator-prey interactions occurred in the ocean covering what is now South Australia between a small, shelled animal distantly related to brachiopods and an unknown marine animal capable of piercing its shell.
