Extreme supersonic winds measured on planet outside our Solar System

Astronomers have discovered extremely powerful winds pummeling the equator of WASP-127b, a giant exoplanet. Reaching speeds up to 33,000 km/h, the winds make up the fastest jet-stream of its kind ever measured on a planet. The discovery provides unique insights into the weather patterns of a distant world.

Why our biological clock ticks: Research reconciles major theories of aging

Two major theories of aging both involve DNA, but in very different ways. Researchers have revealed that these theories may not be so different after all.

First fast radio burst traced to old, dead, elliptical galaxy

Astronomers previously thought all FRBs were generated by magnetars formed through the explosions of very young, massive stars. But new FRB is pinpointed to the outskirts of 11.3-billion-year-old galaxy without young, active stars -- calling those assumptions into question. 'Just when you think you understand an astrophysical phenomenon, the universe turns around and surprises us,' researcher says.

Ancient viral DNA shapes early embryo development

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the 'dark side' of the genome, researchers have now revealed their crucial role in early embryo development.

Insights into how populations conform or go against the crowd

Cultural traits -- the information, beliefs, behaviors, customs, and practices that shape the character of a population -- are influenced by conformity, the tendency to align with others, or anti-conformity, the choice to deliberately diverge. A new way to model this dynamic interplay could ultimately help explain societal phenomena like political polarization, cultural trends, and the spread of misinformation.

The universe is expanding too fast to fit theories: Hubble tension in crisis

The Universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous -- and highly debated -- results had shown: The Universe is expanding faster than predicted by theoretical models, and faster than can be explained by our current understanding of physics. This discrepancy between model and data became known as the Hubble tension. Now, results provide even stronger support to the faster rate of expansion.

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.

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.

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.

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.
