Scientists have recently discovered a new species of the oldest carnivorous dinosaur in the UK. The dinosaur is believed to be the oldest-known meat-eating dinosaur that lived over 200 million years ago. Scientists realized that the dinosaur relates to an entirely new species called Pendraig milnerae. It has been named in honor of trailblazing Museum…
Scientists from the Department of Radiology at NYU Langone Health and its Laura and Isaac Perlmutter Cancer Center have trained a computer program for better breast cancer diagnosis. Their new AI has been trained among thousands of breast ultrasound images. When tested on 44,755 already completed ultrasound exams, the AI effectively improved radiologists’ ability to…
Effective disinfection technology to combat SARS-CoV-2 can help reduce viral transmissions. Ultraviolet (UV) devices emitting UVC irradiation have proven to be effective for virus disinfection. However, there is minimal information available for SARS-CoV-2 due to the safety requirements of testing. A new study by the CU boulder suggests that a specific wavelength of Far ultraviolet-C,…
How long, on average, a free neutron lives outside the confines of atomic nuclei? To find out the answer, an international team of physicists led by Indiana University conducted an experiment that captured neutrons. The temperatures of these neutrons are lowered to nearly absolute zero inside a “bathtub” lined with about 4,000 magnets. After waiting…
Using W. M. Keck Observatory on Maunakea in Hawaii, astronomers have discovered a planetary system consisting of a Jupiter-like planet with a Jupiter-like orbit revolving around a white dwarf star. Lies about a quarter of the way towards the center of our Milky Way galaxy, the gas giant planet within the system just survived the…
Using all-optical methods, scientists from Skoltech and the University of Southampton, U.K., have created an artificial lattice called Lieb lattice. All nodes in the lattice hold polaritons- quasiparticles that are half-light and half-matter excitations in semiconductors. Thi laser-generated polariton lattice allowed scientists to demonstrate breakthrough results significant for condensed matter physics. It can be used…
An international research team, led by the University of Canterbury‘s Professor Rudi Marquez, has developed a new wound gel that promises horses and humans. This new wound gel will be used to treat foot ulcers and kick-starts tissue regeneration. As scientists noted, it could have a significant impact on healing horses and humans alike. To…
Thanks to optical communication, it becomes possible to transfer information over very long distances using light or radio waves. The technology has applications such as space communication and fiber optic cables for internet traffic. But, it has a limitation- as it uses light to transfer information between two distant points, it loses power along the…
NASA’s Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile looked at the universe when it was 3 billion years old. The telescopes found six early, massive, ‘dead’ galaxies that are running on empty. Meanwhile, the galaxies have no fuel, i.e., cold hydrogen gas needed for star formation. The discovery of…
People with diabetes either need to collect blood samples or embed sensors into their skin to monitor glucose levels. Both ways are painful. Now, Penn State scientists have developed a new wearable device to measure blood sugar levels. The device is less intrusive, noninvasive, and low-cost. It is able to monitor glucose levels in sweat…
