The US National Oceanic and Atmospheric Administration says it is discontinuing its regular update calls due to staffing problems, but its researchers may also fear political retaliation for discussing climate change
Many people will soon load up Easter baskets with chocolate candy for children and adults to enjoy. On its own, dark chocolate has health benefits, such as antioxidants that neutralize damaging free radicals. And a new report suggests that packing the sweet treat with pre- and probiotics could make it more healthful. Flavoring agents, however, can affect many properties, including moisture level and protein content of the chocolate product.
Researchers have advanced a decades-old challenge in the field of organic semiconductors, opening new possibilities for the future of electronics. The researchers have created an organic semiconductor that forces electrons to move in a spiral pattern, which could improve the efficiency of OLED displays in television and smartphone screens, or power next-generation computing technologies such as spintronics and quantum computing.

Astronomers have constructed the first detailed 3D map of the properties of cosmic dust in our home galaxy. For their map, the astronomers used 130 million spectra from ESA's Gaia mission, results from the LAMOST spectral survey, and machine learning. Dust makes distant astronomical objects appear more reddish and dimmer than they really are, so the new map will be an important tool for astronomers to make sense of their observations. The study has also revealed unusual properties of cosmic dust that will lead to further research.
A study highlights a new approach in addressing conductive hearing loss. A team of scientists has designed a new type of hearing aid that not only improves hearing but also offers a safe, non-invasive alternative to implantable devices and corrective surgeries.
A study of the fossilised fur of six mammals from the Jurassic and Cretaceous periods has found they were all greyish-brown in colour, which would have helped them hide from dinosaurs
The 2023 breach of the Kakhovka dam drained a huge reservoir and exposed a vast area of toxic sediment, creating a debate about how best to rebuild after the Russia-Ukraine war
Potential cuts of up to 50 per cent of NASA's science budget could mean cancelling missions including the Hubble Space Telescope and the Voyager probes
If Mars Samples Contain Life, Can We Detect It?
At least two mass extinction events in Earth's history were likely caused by the 'devastating' effects of nearby supernova explosions, a new study suggests. Researchers say these super-powerful blasts -- caused by the death of a massive star -- may have previously stripped our planet's atmosphere of its ozone, sparked acid rain and exposed life to harmful ultraviolet radiation from the Sun. They believe a supernova explosion close to Earth could be to blame for both the late Devonian and Ordovician extinction events, which occurred 372 and 445 million years ago respectively.
Scientists improved battery durability and energy density with a nano-spring coating.
Researchers have performed the first imaging of embryos using cameras designed for quantum measurements. The academics investigated how to best use ultrasensitive camera technology, including the latest generation of cameras that can count individual packets of light energy at each pixel, for life sciences.
Industrial waste gases, long seen as a major contributor to climate change, could soon be captured and repurposed into everyday household products such as shampoo, detergent, and even fuel.
Some of the world's most advanced AI systems struggle to tell the time and work out dates on calendars, a study suggests.
A modulator has now broken the terahertz mark. The ultrafast component efficiently transmits large volumes of data into the fiber-optic network in a short space of time.

With today's data rates of only a few hundred megabytes per second, access to digital information remains relatively slow. Initial experiments have already shown a promising new strategy: Magnetic states can be read out by short current pulses, whereby recently discovered spintronic effects in purpose-built material systems could remove previous speed restrictions. Researchers are now providing proof of the feasibility of such ultrafast data sources. Instead of electrical pulses, they use ultrashort terahertz light pulses, thereby enabling the read-out of magnetic structures within picoseconds.

Researchers have discovered a handful of new CRISPR-Cas systems that could add to the capabilities of the already transformational gene editing and DNA manipulation toolbox. Of the new recruits, one system from bacteria commonly found in dairy cows shows particular promise for human health.
