| Novel way to perform ‘general inverse design’ with high accuracy Posted: 06 Jan 2022 11:37 AM PST 'Inverse design' is a design approach that reverses the traditional design process and enables the designer to discover and create materials that possess a user-defined set of properties. Researchers demonstrate a nascent machine learning-based solution that uses an algorithm to identify any material that exhibits specific properties or characteristics. Termed 'general inverse design,' the novel method is not limited to a particular set of elements or crystal structure, but accesses all elements and crystal structures and can design novel compounds different from known materials. |

| Posted: 06 Jan 2022 11:32 AM PST A pioneering type of patented computer memory known as ULTRARAM™ has been demonstrated on silicon wafers in what is a major step towards its large-scale manufacture. ULTRARAM™ is novel type of memory with extraordinary properties. It combines the non-volatility of a data storage memory, like flash, with the speed, energy-efficiency and endurance of a working memory, like DRAM. To do this it utilizes the unique properties of compound semiconductors, commonly used in photonic devices such as LEDS, laser diodes and infrared detectors, but not in digital electronics, which is the preserve of silicon. |
| Posted: 06 Jan 2022 10:32 AM PST No longer solely in the realm of science fiction, the possibility of interstellar travel has appeared, tantalizingly, on the horizon. Although we may not see it in our lifetimes -- at least not some real version of the fictional warp-speeding, hyperdriving, space-folding sort -- we are having early conversations of how life could escape the tether of our solar system, using technology that is within reach. |
| Portable prostate cancer test may help reach underserved men Posted: 05 Jan 2022 05:28 PM PST A highly portable and rapid prostate cancer screening kit could provide early warning to populations with higher incidence of prostate cancer and particularly those with limited access to health care, such as African American men. |
| Physicists watch as ultracold atoms form a crystal of quantum tornadoes Posted: 05 Jan 2022 02:41 PM PST Physicists have directly observed ultracold atoms forming 'quantum tornadoes' in a spinning fluid of ultracold atoms. The observations record a key crossover from classical to quantum behavior. |
| Engineered nanomaterial captures off-target cancer drug to prevent tissue damage Posted: 05 Jan 2022 12:13 PM PST Standard chemotherapies may efficiently kill cancer cells, but they also pose significant risks to healthy cells, resulting in secondary illness and a diminished quality of life for patients. To prevent the previously unavoidable damage, researchers have developed a new class of nanomaterials engineered to capture chemotherapy drugs before they interact with healthy tissue. |
| Engineers develop new software tool to aid material modeling research Posted: 05 Jan 2022 12:13 PM PST A new software tool can accelerate materials science research by cutting out tedious background research on material properties. Researchers recently debuted propSym, an open-source software on the programming platform MATLAB, to calculate the fundamental constants needed to describe the physical properties of solids, such as metals, ceramics or composites. |
| Immuno-CRISPR assay could help diagnose kidney transplant rejection early on Posted: 05 Jan 2022 10:45 AM PST Researchers have developed a CRISPR-based assay that can sensitively and non-invasively detect a biomarker of acute kidney rejection in urine. This could someday help diagnose rejection earlier and without a biopsy. |
| Living in outer space: Changes in blood flow volume may be at the heart of worsening eyesight Posted: 05 Jan 2022 10:45 AM PST The long-term risks of living in space include bone loss, cosmic radiation and muscle weakness, so leaving gravity behind certainly has its obstacles -- and yet, that doesn't stop people from venturing out of the stratosphere. Some of these potential hurdles have already been studied extensively or are currently being investigated, but researchers have found an important but underserved area of space to study: the brain and gravity's effect on eyesight. |
| World’s fastest blade runner gets no competitive advantage from prostheses, study shows Posted: 05 Jan 2022 09:23 AM PST A new study provides the most comprehensive data ever collected from elite runners with bilateral leg amputations, including the world's fastest 400-meter sprinter, Blake Leeper. |
| Windows that outsmart the elements Posted: 05 Jan 2022 09:23 AM PST New research takes energy efficient windows a step further by proposing a new "smart window" design that would harvest the sun's energy in the winter to warm the house and reflect it in the summer to keep it cool. |
| The first topological acoustic transistor Posted: 05 Jan 2022 08:13 AM PST Researchers have designed and simulated the first topological acoustic transistors -- with sound waves instead of electrons -- and proposed a connection architecture to form a universal logic gate that can switch the flow of sound on and off. |
| Earth isn’t 'super' because the sun had rings before planets Posted: 05 Jan 2022 07:32 AM PST Before the solar system had planets, the sun had rings -- bands of dust and gas similar to Saturn's rings -- that likely played a role in Earth's formation, according to a new study. |
| Climate change could lead to power outages, higher power costs on west coast of US Posted: 05 Jan 2022 07:32 AM PST Two studies project the future of power supply and demand on the West Coast under different scenarios: one under climate change and another where power sources shift toward renewables and the climate follows historic trends. |
| Suppressing the Auger recombination process in quantum dots Posted: 05 Jan 2022 06:45 AM PST Quantum Dot (QD) is a nanometer-sized semiconductor nanocrystal that has unique optical properties such as the ability to emit light in the range of optical frequencies depending on its size. QDs have already been applied to practical optoelectronic applications including light-emitting displays, solar cells, photodetectors, and lasers. |

| Plasma-based engineering creates contact-killing, antifouling, drug-release surfaces Posted: 04 Jan 2022 09:36 AM PST Conventional wet-chemistry methods used to create biocidal materials are complex, time-consuming, and expensive. Researchers present a tutorial in which they explore a promising alternative called plasma-enabled surface engineering. The technology relies on nonequilibrium plasma that produces chemical reactions to change the properties at the material surface. Reactions can be manipulated by adjusting electric power for surface activation, coating deposition, and surface nanostructuring of virtually any solid material. |
| Custom finger clip offers a new way to measure blood pressure, other vitals Posted: 04 Jan 2022 09:35 AM PST Monitoring a person's blood pressure on a regular basis can help health care professionals with early detection of various health problems such as high blood pressure, which has no warning signs or symptoms. However, many things can alter an accurate blood pressure reading, including a patient's nervousness about having their blood pressure taken at a doctor's office, otherwise known as 'white coat syndrome.' Now, researchers are customizing a commercial finger clip device to provide a rapid, noninvasive way for measuring and continually monitoring blood pressure. The device can also simultaneously measure four additional vital signs -- heart rate, blood oxygen saturation, body temperature and respiratory rate. |

| Resolving the black hole ‘fuzzball or wormhole’ debate Posted: 04 Jan 2022 08:22 AM PST Black holes really are giant fuzzballs, a new study says. The study attempts to put to rest the debate over Stephen Hawking's famous information paradox, the problem created by Hawking's conclusion that any data that enters a black hole can never leave. This conclusion accorded with the laws of thermodynamics, but opposed the fundamental laws of quantum mechanics. |
