Medical Xpress / Psychologists say patients are turning to chatbots as mental health professionals
More than three-quarters of psychologists report their patients are discussing artificial intelligence in therapy, using the technology to seek additional support with their mental health, find a diagnosis, or for friendship ...
Medical Xpress / Why some immunotherapy fails: Tumor-triggered neutrophils can shut down cancer-killing T cells
Certain white blood cells in the immune system, known as neutrophils, can make cancer immunotherapy less effective, according to a new study from Karolinska Institutet published in the journal Immunity. The results show that ...
Phys.org / 5.5 magnitude earthquake rattles Tokyo region but no danger of a tsunami, meteorological agency says
An earthquake with a preliminary magnitude of 5.5 shook eastern Japan, including Tokyo, on Tuesday, but there was no danger of a tsunami, the meteorological agency said.
Phys.org / Venus flytrap's snap may come from rapid cell wall softening, not water flow
The Venus flytrap (Dionaea muscipula) is a marvel of nature, a highly effective killer that doesn't have to move an inch to capture and kill its prey. It releases a fruity nectar scent to attract flies and other insects. ...
Medical Xpress / Large-scale population studies needed to reduce risks from newborn genome screening, investigators conclude
New research from large population studies provides invaluable evidence on genome screening of newborn babies to reduce risks from overdiagnosis. The authors conclude that further studies are needed before such screening ...
Medical Xpress / DR Congo Ebola outbreak yet to peak, could last a year: Red Cross
The deadly Ebola outbreak in the DR Congo has yet to peak and could take a year to contain, the Red Cross warned Tuesday, amid mounting warnings of dangerous gaps in the response.
Phys.org / New tool to help build more reliable DNA nanostructures
Scaffolded DNA and RNA origami is a technique that allows scientists to build tiny, highly precise two- and three-dimensional objects. Because these nanostructures can interact naturally with biological systems, they could ...
Phys.org / Light-programmed system projects 28-layer 3D images in single shot
Researchers at the UCLA Samueli School of Engineering and CNSI (California NanoSystems Institute), led by Professor Aydogan Ozcan, introduced a snapshot 3D image projection system that integrates a digital encoder with a ...
Phys.org / Electron matter waves gain ultrafast torque that flips handedness in femtoseconds
Many natural processes, ranging from magnetism to chemical reactions, entail the movement and rotation of particles at very small scales. In quantum mechanics, particles exhibit both particle-like and wave-like behaviors, ...
Phys.org / Human evolution was messy and gradual, not an abrupt revolution, argues archaeologist
It is generally accepted by archaeologists that modern humans originated in Africa and dispersed worldwide, while other hominins went extinct. Yet how and when Homo sapiens dispersed out of Africa, and whether it was an abrupt ...
Phys.org / Public school closings in Chicago linked to more gun violence in nearby neighborhoods
In 2013, Chicago Public Schools closed 49 elementary schools—the largest mass public school closure in U.S. history at the time. A new study from researchers at the University of Chicago and the Johns Hopkins Bloomberg School ...
Tech Xplore / Simple color cue helps people master prosthetic devices faster
Controlling a robotic arm, a prosthetic hand or a rehabilitation device is harder than it looks. Picking up an egg, for example, requires just the right amount of force: too little and it falls, too much and it breaks.
