OAK BROOK, Ill. - A novel technique that delivers high doses of radiation to tumors while sparing the surrounding normal tissue shows promise as a curative treatment option for patients with early-stage liver cancer, according to a study published online in the journal Radiology.
A new RAND Corporation paper finds that artificial intelligence has the potential to upend the foundations of nuclear deterrence by the year 2040.
While AI-controlled doomsday machines are considered unlikely, the hazards of artificial intelligence for nuclear security lie instead in its potential to encourage humans to take potentially apocalyptic risks, according to the paper.
The southwest Indian Ocean cyclone season started on November 15, 2017 and will officially end on April 30, 2018. A tropical cyclone called Fakir formed on April 23 near northeastern Madagascar and the Global Precipitation Measurement mission or GPM core satellite looked at the storm's rainfall rates.
Fakir is expected to intensify as it moves toward the southeast and could be a significant tropical cyclone tomorrow. This cyclone season has already seen Madagascar battered and drenched by tropical cyclones Ava, Dumazile, and Eliakim.
CHAPEL HILL - Cancer that has spread, or metastasized, from its original site to other tissues and organs in the body is a leading cause of cancer death. Unfortunately, research focused on metastatic disease has been limited by a lack of experimental systems that mimic the way metastatic cancers grow in people.
Using a technology that provides a 'high-resolution view' of the status of individual cells, a team of researchers has gained new insights into the embryonic development of the mouse heart. They discovered that during development, when progenitor heart cells progressively differentiate into various cell types, the Hippo pathway is essential to coordinate the development of these cell types into a working heart. The study appears in the journal Developmental Cell.
Trees cool their environment and "heat islands" like Munich benefit from it. However, the degree of cooling depends greatly on the tree species and the local conditions. In a recent study, scientists at the Technical University of Munich (TUM) compared two species of urban trees.
A new study by Murtuza Jadliwala, assistant professor of computer science at The University of Texas at San Antonio, examines wearable technology and whether it affects drivers' concentration. Jadliwala and his collaborators discovered that while a driver texting with a wearable device can marginally reduce their level of distraction, it ultimately makes texting while driving just as dangerous as with an ordinary cell phone.
Ever since scientists realized that humans evolved from a succession of primate ancestors, the public imagination has been focused on the inflection point when those ancestors switched from ape-like shuffling to walking upright as we do today. Scientists have long been focused on the question, too, because the answer is important to understanding how our ancestors lived, hunted and evolved.
Madrid, Spain: Outbreaks of the fungal pathogen Candida auris (C. auris) in healthcare settings, particularly in intensive care units (ICUs), may be linked to multi-use patient equipment, such as thermometers, according to research presented at the 28th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID) [1].
COLUMBUS, Ohio--You can wear an exoskeleton, but it won't turn you into a superhero.
That's the finding of a study in which researchers tested a commercially available exoskeleton--a mechanical arm attached to a harness--that's typically worn by workers to help them carry heavy objects hands-free.
In the journal Applied Ergonomics, the researchers report that that the device relieved stress on the arms just as it was supposed to--but it increased stress on the back by more than 50 percent.
In a recent study published in Science, researchers at ICFO - The Institute of Photonic Sciences in Barcelona, Spain, along with other members of the Graphene Flagship, reached the ultimate level of light confinement. They have been able to confine light down to a space one atom, the smallest possible. This will pave the way to ultra-small optical switches, detectors and sensors.
Researchers from LSTM, with partners from a number of international institutions, have shown the rapid selection of a novel P450 enzyme leading to insecticide resistance in a major malaria vector.
Ljubljana, Slovenia - 20 April 2018: Faster walking patients with heart disease are hospitalised less, according to research presented today at EuroPrevent 2018, a European Society of Cardiology congress, and published in the European Journal of Preventive Cardiology.1,2
The three-year study was conducted in 1,078 hypertensive patients, of whom 85% also had coronary heart disease and 15% also had valve disease.
CAMBRIDGE, MASS.--Two and a half years ago, a team of researchers led by groups at MIT, the University of California at Berkeley, and Boston University announced a milestone: the fabrication of a working microprocessor, built using only existing manufacturing processes, that integrated electronic and optical components on the same chip.
A community's ability to cope with mass casualty incidents (MCIs) is very dependent on the capacity and capability of its hospitals for handling a sudden surge of patients requiring resource-intensive and specialized needs.
