A planet that should not exist

Astronomers detected a massive planet, GJ 3512b, orbiting the small red dwarf star GJ 3512, defying predictions of theoretical models. The discovery poses questions about planetary formation mechanisms and encourages further research.

Found: Fastest eclipsing binary, a valuable target for gravitational wave studies

The discovery of ZTF J1539+5027 is the fastest known eclipsing white dwarf binary, with an orbit period of only 6.91 minutes, making it a valuable target for gravitational wave studies. The system is expected to be one of the strongest sources of gravitational waves detectable by LISA, the future space-based gravitational wave detector.

Supernova observation first of its kind using NASA satellite

A team of astronomers at Ohio State University used NASA's Transiting Exoplanet Survey Satellite to observe a Type Ia supernova, the first of its kind to measure hydrogen in its spectra. The discovery challenges traditional theories on why white dwarf stars explode and could provide new insights into the elements left behind.

Energy-saving new LED phosphor

Chemists at the University of Innsbruck have created a novel red phosphor called SALON, which emits light in the visible red range and reduces energy loss. This breakthrough could lead to more efficient white LEDs with improved color quality.

Just add heat to open this tiny box

Scientists have created nanocubes that can form stable cubes at specific temperatures, then scramble back into individual components when heated or cooled. This self-assembly ability mimics life's chemical processes, enabling the creation of complex systems.

Eating small amounts of red and processed meats may increase risk of death

A new study found that consuming even small amounts of red meat may increase the risk of death from all causes, especially cardiovascular disease. The research, part of the Adventist Health Study-2, analyzed over 7,900 individuals and found a significant association between low intake of red and processed meats and higher risks of tota...

Parasites from patients with cerebral malaria stick preferentially in their brains

Researchers found that infected red blood cells from cerebral malaria patients bind more strongly to brain-derived cells than those from uncomplicated malaria patients. This suggests that specific PfEMP1 proteins on the infected red blood cells allow for efficient binding to brain vessels, a key feature of cerebral malaria.

Thousands of stars turning into crystals

Astronomers have found the first direct evidence of white dwarf stars solidifying into crystals, which could make them billions of years older than previously thought. This discovery has been published in Nature and is based on observations taken with the European Space Agency's Gaia satellite.

Dark matter on the move

Scientists have discovered that dark matter can be heated up and pushed outwards due to star formation in galaxies. This phenomenon, known as 'dark matter heating', has been observed in 16 dwarf galaxies with varying star formation histories.

Study links frequent red meat consumption to high levels of chemical associated with heart disease

Researchers found that people who eat a diet rich in red meat have triple the TMAO levels of those who eat a diet rich in either white meat or mostly plant-based proteins. However, discontinuation of red meat eventually lowers these TMAO levels, suggesting a promising new strategy for individualizing diets and preventing heart disease.

Ultra-hot gas around remnants of sun-like stars

Researchers have found an extremely hot magnetosphere around a white dwarf, a remnant of a star like our Sun. This discovery sheds light on the origin of highly ionised metals in some white dwarfs, which were previously a puzzle. The study reveals that the magnetic field traps material flowing from the surface, heating it up dramatically.

Researchers discover new type of stellar collision

An international team of astrophysicists has identified the first-ever merger of white and brown dwarf stars, with the debris left behind exhibiting unusual chemical compositions and organic molecules. The discovery sheds new light on the origin of a mysterious star observed by French monk Père Dom Anthelme in 1670.
