Tech Xplore / Upsampling method sharpens AI vision with up to 16 times less GPU memory
From facial recognition on smartphones to humanoid robots, computer vision technology, which serves as the eyes of artificial intelligence (AI), is widely used in daily life. A joint research team from KAIST and international ...
Phys.org / Radiocarbon dating confirms 10,000 years of continuous human occupation in the Pyrenees
Researchers from the Universitat Autònoma de Barcelona (UAB) have created an open database with 124 carbon-14-dated samples that have made it possible to construct the chronological sequence of 380 sites located in the Aigüestortes ...
Phys.org / Reversible chirality switching in MoS₂ generates spin currents without magnets
A newly developed method allows researchers to dynamically switch chirality—a particular lack of mirror symmetry—to generate spin currents in semiconductors, researchers from Science Tokyo report. Their approach relies on ...
Phys.org / Burned as waste for years, this overlooked plant material is poised to reshape how nylon gets made
Most people have seen nylon listed as a material on their clothing tags, but nylon is used in an array of other products, too, including automotive parts, wire insulation and medical supplies. Unfortunately, one of the building ...
Phys.org / Frozen Greenland middens preserve 4,500 years of farms, seal hunts and toilets
Greenland has a long and checkered history of human settlement: several Paleo-Inuit cultures since approximately 2,500 BCE, descendants of Vikings between the 10th and 15th centuries, and early modern Danes since 1721. All ...
Tech Xplore / Aperture-tuning antenna keeps 5G signals strong across wider frequencies
A compact aperture-adjustable antenna developed by researchers at Science Tokyo could improve high-speed wireless communication across the wide 5G millimeter-wave frequency bands without increasing power consumption. The ...
Phys.org / Semiconductor chip writes 64 DNA sequences in water, setting new enzymatic benchmark
Silicon chips have powered computing for half a century. Increasingly, they are also becoming platforms to read and manipulate biology at scale—recording from many neurons, reading many DNA sequences and now synthesizing ...
Phys.org / Bird flu kills 13,000 seal pups on remote Australian island
A pathogenic strain of bird flu killed more than 13,000 elephant seal pups after infecting a breeding colony on a sub-Antarctic volcanic island, Australian scientists said Thursday.
Phys.org / Medieval Moroccan bathhouse steps reveal rare game board
Archaeologists have discovered a game board carved into the steps of a medieval bathhouse in the Moroccan town of Walīla (the Roman city of Volubilis). The find is a rare example of a medieval game board that can be securely ...
Phys.org / Dark biodiversity helps solve Darwin's 160-year-old puzzle
An international research team, which included University of Tartu visiting doctoral student Wen-Gang Zhang and Professor of Botany Meelis Pärtel, has found a new solution to one of ecology's long-standing controversies—Darwin's ...
Medical Xpress / Key factors that build resilience and support mental health in female athletes identified
Researchers have identified several modifiable factors that influence psychological resilience in female athletes and found that greater resilience may help protect against depression, anxiety, post-traumatic stress disorder ...
Medical Xpress / An experimental molecule 'reprograms' the brain's defenses against Alzheimer's disease
A team has identified an experimental molecule capable of "reprogramming" the brain's immune cells to restore part of their protective function against Alzheimer's disease. The study, published in the journal Cell Death and ...
