CHOP researchers establish novel approach for developing new antibiotics

Jul 19 2021 - 00:07
Researchers at Children's Hospital of Philadelphia (CHOP) have developed a novel method for producing new antibiotics to combat resistant bacteria. Through an approach that would target bacteria with an antibiotic that is masked by a prodrug, which the bacteria would themselves remove, the researchers identified a method that would allow for development of new, effective antibiotics that could overcome issues of resistance. The findings were published today in eLife.

Bats in Tel Aviv enjoy the rich variety and abundance of food the city has to offer

Jul 19 2021 - 00:07
Researchers have found that when fruit bats forage in the city (Tel Aviv), they are much more exploratory and enjoy the diversity of urban life, visiting a variety of fruit trees every night and tasting as wide a variety of foods as possible. In contrast, rural bats living in Beit Guvrin focus on only one or two fruit trees every night.

Scientists adopt deep learning for multi-object tracking

Jul 19 2021 - 00:07
Implementing algorithms that can simultaneously track multiple objects is essential to unlock many applications, from autonomous driving to advanced public surveillance. However, it is difficult for computers to discriminate between detected objects based on their appearance. Now, researchers at the Gwangju Institute of Science and Technology (GIST) adapted deep learning techniques in a multi-object tracking framework, overcoming short-term occlusion and achieving remarkable performance without sacrificing computational speed.

Kids' sleep: check in before you switch off

Jul 19 2021 - 00:07
The struggle to get your child to go to sleep and stay asleep is something most parents can relate to. Once the bedtime battle is over and the kids have finally nodded off, many parents tune out as well. But University of South Australia researcher Professor Kurt Lushington is calling for parents to check on their small snoozers before switching off.

At last: Separated and freshly bound

Jul 19 2021 - 00:07
The carbon-hydrogen bonds in alkanes--particularly those at the ends of the molecules, where each carbon has three hydrogen atoms bound to it--are very hard to "crack" if you want to replace the hydrogen atoms with other atoms. Methane (CH(4)) and ethane (CH(3)CH(3)) are made up, exclusively, of such tightly bound hydrogen atoms. In the journal Angewandte Chemie, a team of researchers has now described how they break these bonds while forming new carbon-nitrogen bonds (amidation).

High respiratory efforts in COVID-19 patients could result in self-inflicted lung injury

Jul 19 2021 - 00:07
The impact of high breathing efforts on the lungs of patients suffering with acute respiratory failure due to COVID-19 has been investigated by researchers at the University of Warwick, who assessed the likelihood of resulting lung injury.

A simple compound to control complex gut microbes

Jul 19 2021 - 00:07
Researchers at the RIKEN, Japan have discovered that acetate, a major metabolite produced by some intestinal bacteria, is involved in regulating other intestinal bacteria. Experiments specifically showed that acetate could trigger an immune response against potentially harmful bacteria. These discoveries will lead to the development of new ways to regulate the balance of intestinal bacteria.

Novel techniques extract more accurate data from images degraded by environmental factors

Jul 19 2021 - 00:07
A team of researchers, led by Yale-NUS College Associate Professor of Science (Computer Science) Robby Tan, who is also from the National University of Singapore's Faculty of Engineering, has developed novel approaches using computer vision and deep learning to resolve the problem of low-level vision in videos caused by rain and night-time conditions, as well as improve the accuracy of 3D human pose estimation in videos.

To die or not to die in response to stress, a decision regulated by MK2 protein levels

Jul 19 2021 - 00:07
Researchers at IRB Barcelona unveil a pathway that determines the fate of cells in response to stress conditions and identify an important mechanism that recovers cell balance. The results have been published in the journal PNAS.

Cosmic rays help supernovae explosions pack a bigger punch

Jul 19 2021 - 00:07
The final stage of cataclysmic explosions of dying massive stars, called supernovae, could pack an up to six times bigger punch on the surrounding interstellar gas with the help of cosmic rays, according to a new study led by researchers at the University of Oxford. The work will be presented by PhD student Francisco Rodríguez Montero today (19 July) at the virtual National Astronomy Meeting (NAM 2021).

uOttawa study first to investigate newly introduced butterfly which could become widespread in Canada

Jul 19 2021 - 00:07
This summer, if you see a butterfly with wings that are blue on top with orange spots underneath, you may have crossed paths with a male European Common Blue (or Polyommatus icarus), a newly introduced species in Canada. Could it be a fluke? Probably not, according to a group of researchers from the University of Ottawa who have taken a close look at this captivating blue creature. They are in fact the first to study its ecology.

No stone unturned: An extensive search for cation substitution in lithium-ion batteries

Jul 19 2021 - 00:07
Lithium-ion batteries (LIBs) power all of modern-day electronic devices. However, with the shift from gasoline-powered vehicles to electric counterparts, there is a demand for higher battery capacity. In their quest for higher battery capacity, scientists from Japan devised a low-cost computational technique for extensively screening for atomic substitutions in LIBs to improve their discharge capacity, opening doors to the development of novel alloying materials to boost battery life and new energy storage systems.

Unsustainable Arctic shipping risks accelerating damage to the Arctic environment

Jul 19 2021 - 00:07
The economic and environmental pros and cons of melting Arctic ice creating shorter shipping routes through the polar region are weighed up in ground-breaking research from UCL experts in energy and transport.They conclude that policy makers must properly assess the environmental trade-offs and costs in addition to the commercial benefits and opportunities in Arctic shipping. The authors also want to see more incentives to drive technological developments that will accelerate the uptake of green fuels and technologies.

An automated flight control system for drone swarms has been developed

Jul 19 2021 - 00:07
Creating new procedures that improve mass drone traffic is the purpose of LABYRINTH, a European research project coordinated by the Universidad Carlos III de Madrid (UC3M) with the participation of 13 international organisations within the R&D&I, transport, emergency, and auxiliary services fields. Researchers hope to use these drone swarm applications to improve civil road, train, sea, and air transport, making it safer, more efficient, and more sustainable.

Championing chrononutrition with protein, the morning elixir for muscle growth

Jul 19 2021 - 00:07
Proteins are essential for body growth and muscle building. However, protein metabolism varies depending on the body's internal biological clock. Therefore, it is important to know how distribution of protein intake over the day affects muscles. Researchers from Japan have now found that consumption of proteins at breakfast increases muscle size and function in mice and humans, shedding light on the concept of 'Chrononutrition' that deals with the timing of diets to ensure organ health.
