Medical Xpress / A one-shot flu vaccine can beat avian flu strains before they appear
Scientists have developed a proof-of-concept vaccine that could offer broad protection against all known and emerging variants of highly pathogenic avian influenza (A5) viruses, including those that have yet to evolve. This ...
Phys.org / Caught on camera: Rats snatching bats from the sky at city hibernation sites
For the first time, brown rats have been filmed actively hunting bats, snatching some from the air and capturing others on the ground. The rodents were caught on camera at bat hibernation sites in northern Germany. According ...
Phys.org / Mysterious transient objects in sky linked to nuclear testing and unidentified anomalous phenomena
A new study analyzing historical photographs taken by the Palomar Observatory between 1949 and 1957 has detected several mysterious bright spots in the sky. These transient objects, captured on film before the first satellites ...
Tech Xplore / Teen builds advanced robotic hand from LEGO parts
A talented teenager from the UK has built a four-fingered robotic hand from standard Lego parts that performs almost as well as research-grade robotic hands. The anthropomorphic device can grasp, move and hold objects with ...
Phys.org / How the Mayans were able to accurately predict solar eclipses for centuries
The Maya Civilization, from Central America, was one of the most advanced ancient civilizations, known for its significant achievements in astronomy and mathematics. This includes accurate calendars and detailed celestial ...
Phys.org / Google claims its latest quantum algorithm can outperform supercomputers on a real-world task
Researchers from Google Quantum AI report that their quantum processor, Willow, ran an algorithm for a quantum computer that solved a complex physics problem thousands of times faster than the world's most powerful classical ...
Medical Xpress / Successful experiments reprogram rogue T cells for targeted autoimmune disease therapy
Two teams of researchers have developed a cell reprogramming technology that converts rogue disease-causing T cells from our immune system into protective Tregcells. These cells help ensure that the immune system doesn't ...
Tech Xplore / AI teaches itself and outperforms human-designed algorithms
Like humans, artificial intelligence learns by trial and error, but traditionally, it requires humans to set the ball rolling by designing the algorithms and rules that govern the learning process. However, as AI technology ...
Phys.org / A tiny chip that can help us see deeper into space
A new imaging system could help us see deeper into the universe than ever before. The same powerful technology could also help us analyze the chemical makeup of everyday materials such as food and medicines much faster and ...
Phys.org / Antarctic ice reveals two volcanoes erupting simultaneously may have caused 15th-century cooling
Nearly 600 years ago, a massive volcanic eruption sent clouds of sulfurous gas and ash high into the atmosphere. The blast known as the 1458/59 CE event was so huge that it triggered decades of cooling, especially in the ...
Tech Xplore / New air filter could turn every building into a carbon sink
Despite decades of warnings and increasing efforts to fight climate change, global carbon emissions are still rising. While cutting emissions from the source is a common way we address this problem, another crucial strategy ...
Phys.org / Dust from far side of the moon could reveal more about origin of water in our solar system
Dust brought back to Earth by China's Chang'e-6 mission contains rare meteorite relics that could change our understanding of sources of water and other life-essential ingredients in our solar system.
Tech Xplore / Scientists create a novel hydrogel for unclonable security tags
Encryption technologies are vital in today's digital landscape to protect sensitive information from hackers and prevent fraud. While cutting-edge encryption has been developed for data, sophisticated protection for physical ...
Phys.org / New chemical treatment turns deadly arsenic contaminant into a valuable raw material
Arsenic is a natural component of Earth's crust and highly toxic in its inorganic form. The element is a cause of a global public health crisis, as it is present in groundwater and the drinking water consumed daily by millions ...
Phys.org / Follow-up observations by Webb confirm GRB 250702B is most energetic cosmic explosion ever recorded
Considering the immense size of the universe, it's no surprise that space still holds plenty of secrets for us. Recently, astronomers believe they stumbled upon a kind of cosmic blast never seen before, and it's challenging ...
