Skoltech researchers were able to show that patterns that can cause neural networks to make mistakes in recognizing images are, in effect, akin to Turing patterns found all over the natural world. In the future, this result can be used to design defenses for pattern recognition systems currently vulnerable to attacks. The paper, available as an arXiv preprint, was presented at the 35th AAAI Conference on Artificial Intelligence (AAAI-21).
An enzyme called MARK2 has been identified as a key stress-response switch in cells in a study by researchers at Johns Hopkins Bloomberg School of Public Health. Overactivation of this type of stress response is a possible cause of injury to brain cells in neurodegenerative diseases such as Alzheimer's, Parkinson's, and Amyotrophic Lateral Sclerosis. The discovery will make MARK2 a focus of investigation for its possible role in these diseases, and may ultimately be a target for neurodegenerative disease treatments.
MADISON, Wis. -- Mexican wolves in the American Southwest disappeared more quickly during periods of relaxed legal protections, almost certainly succumbing to poaching, according to new research published Wednesday.
Fossil sites sometimes resemble a living room table on which half a dozen different jigsaw puzzles have been dumped: It is often difficult to say which bone belongs to which animal. Together with colleagues from Switzerland, researchers from the University of Bonn have now presented a method that allows a more certain answer to this question. Their results are published in the journal Palaeontologia Electronica.
Magnetic resonance imaging (MRI) is already widely used in medicine for diagnostic purposes. Hyperpolarized MRI is a more recent development and its research and application potential has yet to be fully explored. Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) have now unveiled a new technique for observing metabolic processes in the body. Their singlet-contrast MRI method employs easily-produced parahydrogen to track biochemical processes in real time.
BOSTON - As COVID-19 infection rates continue to fall, Massachusetts officials are signaling it's almost time to end remote learning and send all school-aged children back to the classroom. While emerging data suggest young children and schools have not been primary drivers of the COVID-19 pandemic, evidence to guide best practices to prevent the spread of the virus in the school setting has been limited and, as a result, national and international recommendations are inconsistent.
Using the same principles that make polarized sunglasses possible, a team of researchers at the Arecibo Observatory in Puerto Rico have developed a technique that will help better defend against asteroids on a collision course with Earth.
A new study recently published in The Planetary Science Journal found a better way to interpret radar signals bounced off asteroids' surfaces. The data can better tell us if an asteroid is porous, fluffy or rocky, which matters because there are hundreds of near-Earth asteroids that could potentially hit the planet.
The universe is filled with magnetic fields. Understanding how magnetic fields are generated and amplified in plasmas is essential to studying how large structures in the universe were formed and how energy is divided throughout the cosmos.
Optical-resolution photoacoustic microscopy (OR-PAM), a new hybrid imaging technique, allows us to listen to the sound of light and see the color of biological tissue itself. It can be used for live, multicontrast functional imaging, but the limited wavelength choice of most commercial lasers and the limitations of the existing scanning methods have meant that OR-PAM can obtain only one or two different types of contrast in a single scan.
Ann Arbor, March 11, 2021 - Black and Hispanic people experience a higher risk for COVID-19 and severe illness, influenced by factors such as discrimination, housing, and healthcare access and utilization. Now, a new study in the American Journal of Preventive Medicine, published by Elsevier, identifies specific job categories that put workers at risk because they require working in close contact with others.
CHAMPAIGN, Ill. -- The chronic stress of living in neighborhoods with high rates of violence and poverty alters gene activity in immune cells, according to a new study of low-income single Black mothers on the South Side of Chicago.
SAN ANTONIO -- Surgically opening the windpipe, or trachea, within the first seven days of the start of mechanical ventilation decreases the time patients spend on ventilators, shortens their ICU stay and lowers their risk of ventilator-associated pneumonia, according to a systematic review published Thursday (March 11) in JAMA Otolaryngology-Head & Neck Surgery.
Crabs are living the meme life on social media lately. The memes joke that everything will eventually look like a crab. But it's actually based in some truth.
As experts nationwide point to a mental health crisis among teens and young adults, a pilot program teaching mindfulness and coping techniques to students at the University of Washington has helped lower stress and improve emotional well-being.
New studies by the psychology researchers who created the program find that the strategies, offered first in residence halls and later through classes and other organized campus groups, have provided participants with successful methods for coping with stress, managing their emotions and learning self-compassion.
In Brazil, a study conducted by researchers affiliated with the University of São Paulo (USP) and collaborators showed that deforestation in the Amazon causes an increase in the diversity of antibiotic-resistant bacteria. An article on the study, published in Soil Biology and Biochemistry, compares the microorganisms that live in the soil of native forest with those found in pasture and croplands.
