For the first time, the Tibet ASγ Experiment has successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec (approximately 3.3 light-years) within the gamma-ray halo surrounding the Geminga pulsar ...

Mitochondria are essential for cell survival, repair, and adaptation. Not only do they generate most of the energy needed during a cell's life, but they also regulate cell death, calcium balance, and responses to stress. ...

Initial tests with a natural dye produced by the Amazonian fungus Talaromyces amestolkiae show that eco-friendly cosmetics, such as face creams, gel sticks, and shampoos, can be developed with antioxidant and antibacterial ...

Electrical engineers at Duke University have demonstrated the fastest pyroelectric photodetector to date, which works by absorbing heat generated by incoming light. Capable of capturing light from the entire electromagnetic ...

Researchers at the University of Innsbruck, together with partners from Sydney and Waterloo, have presented a new diagnostic method for quantum computers. It makes errors in individual quantum bits visible during logical ...

Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images. Yet controlling these properties independently remains difficult, especially ...

An independent researcher claimed on Wednesday that a marble bust of Christ in a Roman church is by Michelangelo, the latest purported attribution to the Renaissance genius who is one of the most imitated artists in the world.

Up to half of the insects in the Amazon region could be exposed to life-threatening heat levels due to progressive, anthropogenic global warming. This is shown by a recent study by the universities of Würzburg and Bremen.

By converting plastic waste into a microbe-friendly food source, scientists have built an upcycling pipeline that turns the waste into a variety of useful products. The findings are detailed in the journal Nature Sustainability.

Every chemical reaction faces a barrier: For substances to react with one another, it is first necessary to supply energy. In many cases, this energy barrier is low—such as when striking a match. For many key reactions ...

Climate change's rising seas may threaten tens of millions more people than scientists and government planners originally thought because of mistaken research assumptions on how high coastal waters already are, a new study ...

Cancer cell-derived small extracellular vesicles (sEVs) can travel from distant tumors through the bloodstream and kidneys and be excreted into urine, as reported by researchers at Science Tokyo. Using sophisticated molecular ...
