May 18, 2023 An unexpected discovery about temperature feedback has led to new bionic technology that allows amputees to sense the temperature of objects ¬-- both hot and cold -- directly in the phantom hand. The technology opens up new avenues for non-invasive ...

May 17, 2023 Researchers trace the origin of certain breast cancers to genomic reshuffling -- rearrangement of chromosomes -- that activates cancer genes and ignites disease. The finding offers a long-missing explanation for many cases of the disease that remain unexplained by the classical model of breast cancer development. The study shows the sex hormone estrogen -- thus far thought to be only a fuel for ...

May 10, 2023 Researchers described the structure of a special type of amyloid beta plaque protein associated with Alzheimer's disease (AD) progression. Scientists showed the small aggregates of the amyloid beta protein could float through the brain tissue fluid, reaching many brain regions and disrupting local neuron functioning. The research also provided ...

May 19, 2023 In nature, the skin of cephalopods (animals with tentacles attached to the head) exhibits unparalleled camouflage ability. Their skin contains pigment groups that can sense changes in environmental light conditions and adjust their appearance through the action of pigment cells. Although intricate in nature, this colour-changing ability is ...

May 18, 2023 The number of qubits in superconducting quantum computers has risen rapidly during the last years, but further growth is limited by the need for ultra-cold operating temperatures. Connecting several smaller processors could create larger, more computationally powerful quantum computers -- however doing so poses new challenges. Researchers have now demonstrated quantum entanglement between optical ...

May 18, 2023 Engineers have developed a prototype metamaterial that uses electrical signals to control both the direction and intensity of energy waves passing through a solid material. Potential applications of this innovative design include military and commercial uses, such as controlling radar waves by directing them to scan a specific area for objects or managing vibration created by air turbulence from ...

May 18, 2023 Researchers report that the financial toll of the climate pattern known as El Niño can persist for several years and cost trillions in lost income worldwide. The study, which is among the first to evaluate the long-term costs of El Niño, found that the 1982 and 1997 events led to $4.1 trillion and $5.7 trillion in lost income in the five years following them. With El Niño projected to return ...

May 18, 2023 Evolution is a sequence of design changes happening on their own in a discernible direction; it never weds itself to a single point on a drawing board. An evolving system or animal is free to simply go with what works. Not so much that its performance suffers greatly, but enough that it opens access to other options near the so-called optimal design. With scientists often looking to nature for ...

May 18, 2023 Scientists have discovered a new species of mosasaur, a sea-dwelling lizard from the age of the dinosaurs, with strange, ridged teeth unlike those of any known reptile. Along with other recent finds from Africa, it suggests that mosasaurs and other marine reptiles were evolving rapidly up until 66 million years ago, when they were wiped out by an asteroid along with the dinosaurs and around 90% ...
