An innovative breast imaging technique provides high sensitivity for detecting cancer while significantly reducing the likelihood of false positive results. Researchers said the technique has the potential to offer more reliable breast cancer screening for a broader range of patients.
Researchers around the world share results from a novel model that can provide tailored predictions of how individual patients respond to different therapies.
Sensory feedback is important for amputees to be able to explore and interact with their environment. Now, researchers have developed a device that allows amputees to sense and respond to temperature by delivering thermal information from the prosthesis' fingertip to the amputee's residual limb. The 'MiniTouch' device uses off-the-shelf electronics, can be integrated into commercially available prosthetic limbs, and does not require surgery. Using the thermally sensitive prosthetic hand, a 57-year-old transradial amputee was able to discriminate between and manually sort objects of different temperatures and sense bodily contact with other humans.
The past year has seen major advances in Large Language Models (LLMs) such as ChatGPT. The ability of these models to interpret and produce human text sources (and other sequence data) has implications for people in many areas of human activity. A new perspective paper argues that like many professionals, neuroscientists can either benefit from partnering with these powerful tools or risk being left behind.
A technique can determine for the first time how frequently, and exactly where, a molecular event called 'backtracking' occurs throughout the genetic material (genome) of any species.
Analysis reveals imported earthworm species have colonized large swaths of North America, and represent a largely overlooked threat to native ecosystems. The researchers warn of the need to better understand and manage the invaders in our midst.
Astronomers have uncovered evidence of how the enigmatic gap in the size distribution of exoplanets at around two Earth radii emerges. Their computer simulations demonstrate that the migration of icy, so-called sub-Neptunes into the inner regions of their planetary systems could account for this phenomenon. As they draw closer to the central star, evaporating water ice forms an atmosphere that makes the planets appear larger than in their frozen state. Simultaneously, smaller rocky planets gradually lose a portion of their original gaseous envelope, causing their measured radius to shrink over time.
Nearly 400 exceptionally well-preserved fossils dating back 470 million years have been discovered in the south of France by two amateur paleontologists. The discovery provides unprecedented information on the polar ecosystems of the Ordovician period.
The new species Trichoglossum syamviswanathii, named after former KFRI director Syam Viswanath, was collected from the moist soil of the Bambusetum of the KFRI Field Research Centre at Palappilly, Thrissur
Dreams of space travel started small with the launch of Sputnik-1 by the Soviet Union, and escalated with the U.S. Apollo landing on the moon in 1969
The Event Horizon Telescope is a worldwide network of radio telescopes that work together
For the first time, pollutants from burning fossil fuels have been found embedded in corals, offering scientists a potential new tool to track the history of pollution, finds a new study.
The onset of psychosis can be predicted before it occurs, using a machine-learning tool which can classify MRI brain scans into those who are healthy and those at risk of a psychotic episode.
In a win for chemistry, inventors have designed a closed-loop path for synthesizing an exceptionally tough carbon-fiber-reinforced polymer and later recovering all of its starting materials.
PFAS have earned the name 'forever chemicals' with good reason -- the human-made compounds, which can take thousands of years to degrade and are found in everything from grease-resistant food packaging to water-repellent clothing, have made their way into nearly half the U.S. tap water supply.
A new technique can control a larger number of microscopic defects in a diamond. These defects can be used as qubits for quantum sensing applications, and being able to control a greater number of qubits would improve the sensitivity of such devices.
Lung tumors called adenocarcinomas sometimes respond to initially effective treatments by transforming into a much more aggressive small cell lung cancer (SCLC) that spreads rapidly and has few options for treatment. Researchers have developed a mouse model that illuminates this problematic process, known as histological transformation. The findings advance the understanding of how mutated genes can trigger cancer evolution and suggest targets for more effective treatments.
Health care providers in developing countries know that oral rehydration salts (ORS) are a lifesaving and inexpensive treatment for diarrheal disease, a leading cause of death for children worldwide -- yet few prescribe it. A new study suggests that closing the knowledge gap between what treatments health care providers think patients want and what treatments patients really want could help save half a million lives a year and reduce unnecessary use of antibiotics.
Scientists have discovered that nighttime air pollution -- coming primarily form car exhaust and power plant emissions -- is responsible for a major drop in nighttime pollinator activity. Nitrate radicals (NO3) in the air degrade the scent chemicals released by a common wildflower, drastically reducing the scent-based cues that its chief pollinators rely on to locate the flower. The findings show how nighttime pollution creates a chain of chemical reactions that degrades scent cues, leaving flowers undetectable by smell. The researchers also determined that pollution likely has worldwide impacts on pollination.
