In collaboration with the Technical University of Denmark (DTU), the Department of Engineering at Aarhus University has developed photonic sensor technology that can pave the way for a portable, reliable and, above all, inexpensive device for detecting ammonia and other gases in agriculture.
Working with chemists and chemical engineers, photonics researchers from Aarhus University and DTU have developed a new sensor system that could contribute to a significant reduction in air pollution in Denmark.
According to scientific estimations, humans are exposed to at least 10,000 to 100,000 environmental and exogenous compounds in an individual lifetime, which are mainly absorbed through our dietary. "Our body can effectively detoxify most of these substances, but various molecules as well as co-exposures can impact drug efficacy," says Benedikt Warth, deputy head of the Department of Food Chemistry and Toxicology at the Faculty of Chemistry and coordinator of the newly founded national exposome research infrastructure, EIRENE Austria.
In The Social Dilemma, the Netflix documentary that has been in the news recently for its radical revelations, former executives at major technology companies like Facebook, Twitter, and Instagram, among others, share how their ex-employers have developed sophisticated algorithms that not only predict users' actions but also know which content will keep them hooked on their platforms. The knowledge that technology companies are preying on their users' digital activities without their consent and awareness is well-known.
Plants have the unique capability to sense and adapt to changes in their environment
This information is stored in the form of 'epigenetic memory' which can be passed on to the offspring, resulting in defects in growth and development.
Researchers have identified two proteins responsible for erasing plant memory to maximise chances of offspring survival.
Researchers at the University of Warwick have uncovered the mechanism that allows plants to pass on their 'memories' to offspring, which results in growth and developmental defects.
Scientists have broken the rules of enzyme engineering to unlock a new method for creating chemical reactions that could unlock a wide range of new applications - from creating new drugs to food production.
In their paper published today in Nature Catalysis, Professor Francesca Paradisi and Dr. Martina Contente of the University of Nottingham and the University of Bern show a new method to produce chemical molecules more efficiently through a new one step reaction in the enzyme.
DOAC (direct oral anticoagulant) pills are used in the treatment of atrial fibrillation by preventing blood clots. Even though blood clots are thought to contribute to complications from the new coronavirus infection, users of this class of drug do not seem to be protected against severe COVID-19, reports a large Swedish registry study from Karolinska Institutet published in The Journal of Internal Medicine.
HSE University scientists have for the first time in the world investigated the impact of delayed reinforcement signals in neurofeedback (NFB) training. They have experimentally proven that reducing the delay in feedback (decreasing feedback latency) can significantly increase the efficacy of training. This opens up new potential for the use of NFB for cognitive enhancement, self-regulation, and the treatment of a broad range of neurological disorders from anxeity and depression to epilepsy.
Tissue oxygenation is a measure of the oxygen level in biological tissue and is a useful clinical biomarker for tissue viability. Abnormal levels may indicate the presence of conditions such as sepsis, diabetes, viral infection, or pulmonary disease, and effective monitoring is important for surgical guidance as well as medical care.
You don't need a sledgehammer to crack a nut.
Jonathan Frankle is researching artificial intelligence -- not noshing pistachios -- but the same philosophy applies to his "lottery ticket hypothesis." It posits that, hidden within massive neural networks, leaner subnetworks can complete the same task more efficiently. The trick is finding those "lucky" subnetworks, dubbed winning lottery tickets.
COLUMBIA, Mo. -- After Jo-Ana Chase heard her mother had successful heart surgery, she was relieved when her mom was finally discharged from the hospital and sent home to be cared for by her brother. However, Chase quickly learned from her brother that he felt lost on the best ways to care for their mom due to confusing discharge instructions from the hospital and logistical challenges related to home health care services like wound care and medication management.
CLEVELAND--A team of researchers at the Case Western Reserve University School of Medicine has taken a major step toward understanding the mechanisms involved in the formation of large clumps of tau protein, a hallmark of Alzheimer's disease and several other neurodegenerative disorders.
Their findings may help to better understand the pathological process and possibly lead to developing medications to treat such devastating brain diseases.
Treatments that harness the immune system to fight cancer have greatly improved outcomes for some people with cancer. Scientists are learning more about why some people respond much better than others to these drugs.
As cars keep getting smarter, automation is taking many tricky tasks --?from parallel parking to backing up --?out of drivers' hands.
Now, a University of Toronto Engineering study is underscoring the importance of drivers keeping their eyes on the road -- even when they are in an automated vehicle (AV).
Using an AV driving simulator and eye-tracking equipment, Professor Birsen Donmez and her team studied two types of in-vehicle displays and their effects on the driving behaviours of 48 participants.
ABERDEEN PROVING GROUND, Md. -- Imagine a silent helicopter stealthily moving troops and supplies around a future battlefield. U.S. Army researchers look to helicopter noise reduction technology as a top priority in aircraft design.
At the U.S. Army Combat Capabilities Development Command, now known as DEVCOM, Army Research Laboratory, researchers collaborated with Uber and the University of Texas at Austin to investigate the acoustic properties of electric vertical takeoff and landing aircraft, which use distributed electric propulsion to power flight.
