A team of researchers from Yale-NUS College, in collaboration with scientists in Sweden, has found that bisulphate species in the exhaust stream are strongly connected to decreasing the effectiveness of exhaust remediation catalysts in diesel engines. Their findings pave the way for synthesising more sulphur-tolerant catalysts and developing regeneration strategies for catalyst systems on diesel-powered freight vehicles. This could lead to lower emission of highly toxic nitrogen oxides from diesel engines, hence reducing pollution.
Bots are social media accounts which are controlled by artificial software rather than by humans and serve a variety of purposes from news aggregation to automated customer assistance for online retailers. However, bots have recently been under the spotlight as they are regularly employed as part of large-scale efforts on social media to manipulate public opinion, such as during electoral campaigns.
To combat weeds, farmers use a variety of tools and methods. By understanding the strengths and downfalls of each tool, a farmer can make the best decisions for his or her operation to keep pesky weeds out of the field.
One tool farmers can turn to for weed control is applying herbicides. New research is helping us understand a specific herbicide even better: atrazine.
Hunter-gatherer groups living in the Baltic between seven and a half and six thousand years ago had culturally distinct cuisines, analysis of ancient pottery fragments has revealed.
An international team of researchers analysed over 500 hunter-gatherer vessels from 61 archaeological sites throughout the Baltic region.
Capping decades of research, a new study may offer a breakthrough in treating dyskeratosis congenita and other so-called telomere diseases, in which cells age prematurely.
Unlike animals, which only digest proteins, carbohydrates and fats, microorganisms also feed on a variety of other organic compounds. Even natural gas does not stop them. Researchers from Bremen have now discovered a microbe in the deep sea that eats ethane, which, with a share of up to 15%, is the second most common component of natural gas.
Life in the extreme
While energy sources such as wind and solar are great at producing emissions-free electricity, they depend on the sun and the wind, so supply doesn't always meet the demand. Likewise, nuclear power plants operate more efficiently at maximum capacity so that electricity generation can't be easily ramped up or down to match demand.
For decades, energy researchers have tried to solve one big challenge: How do you store excess electricity so it can be released back onto the grid when it's needed?
PULLMAN, Wash. - During this pandemic when few parents can limit screen time, a new study shows that building critical media skills as a family can have a positive impact on kids' nutrition without restricting their access to TV and computers.
The study, published in the journal Childhood Obesity on April 20, found that an education program that had parents and kids learn media literacy skills together not only helped children eat more fruits and vegetables but also improved communication between parents and their kids.
This summer, NASA plans to launch its next Mars rover, Perseverance, which will carry with it the first aircraft to ever fly on another planet, the Mars Helicopter. As the first of its kind, the Mars Helicopter will carry no instruments and collect no data -- NASA describes merely flying it all as "high-risk, high-reward" research.
With the risks of extraterrestrial flight in mind, Penn Engineers are suggesting a different approach to exploring the skies of other worlds: a fleet of tiny aircraft that each weigh about as much as a fruit fly and have no moving parts.
Can staying up late make you fat? A growing body of research has suggested that poor sleep quality is linked to an increased risk of obesity by deregulating appetite, which in turn leads to more calorie consumption.
Researchers from Michigan State University released a study on "sextortion" - a lesser-known internet crime that poses a threat to adults and minors - that sheds light on the importance of protecting the public from online criminals.
Skoltech researchers have presented a new biological image processing method that accurately picks out specific biological objects in complex images. Their results will be presented as an oral talk at the high-profile computer vision conference, CVPR 2020.
Biologists get a wealth of information in the form of biological images, which makes their automatic processing a formidable task. Researchers often have to handle images with a large number of objects, which is especially hard when it comes to microscopy images with overlapping objects and poor image quality and sharpness.
WASHINGTON, April 21, 2020 -- The advent of artificial intelligence, machine learning and the internet of things is expected to change modern electronics and bring forth the fourth Industrial Revolution. The pressing question for many researchers is how to handle this technological revolution.
A genetic change increases the risk of developing schizophrenia and highlights new opportunities for drug treatment say researchers.
The collaborative research by a team from Lancaster, Glasgow and Strathclyde Universities was funded by the Medical Research Council.
WEST LAFAYETTE, Ind. -- Repetitive hits to the head can cause brain damage without actually leading to a concussion, past studies have suggested.
Just a simple change to the starting stance of players on the offensive line in American football might reduce this burden, a study conducted by Purdue University and Stanford University researchers now shows.
