How tumors make immune cells 'go bad'

Posted: 21 Jun 2022 11:18 AM PDT

Robotic lightning bugs take flight

Posted: 21 Jun 2022 11:18 AM PDT

Inspired by fireflies, researchers created soft actuators that can emit light in different colors or patterns. These artificial muscles, which control the wings of featherweight flying robots, light up while the robot is in flight, which provides a low-cost way to track the robots and also could enable them to communicate.

Walking gives the brain a 'step-up' in function for some

Posted: 21 Jun 2022 11:17 AM PDT

It has long been thought that when walking is combined with a task -- both suffer. Researchers have now found that this is not always the case. Some young and healthy people improve performance on cognitive tasks while walking by changing the use of neural resources.

Genetic mutations enable efficient evolution of TB-causing bacteria

Posted: 21 Jun 2022 08:47 AM PDT

Researchers have identified how the bacterium that causes tuberculosis (TB) can evolve rapidly in response to new environments.

Vitamins, supplements are a 'waste of money' for most Americans

Posted: 21 Jun 2022 08:47 AM PDT

Scientists say for non-pregnant, otherwise healthy Americans, vitamins are a waste of money because there isn't enough evidence they help prevent cardiovascular disease or cancer. They've written an editorial in support of new recommendations that state there was 'insufficient evidence' that taking multivitamins, paired supplements or single supplements can help prevent cardiovascular disease and cancer in otherwise healthy, non-pregnant adults.

Global AFib study finds simple ablation has best outcomes

Posted: 21 Jun 2022 08:47 AM PDT

Results from one of the largest global studies of atrial fibrillation (AFib) procedures show that the simple approach is usually best when it comes to ablation, a procedure where physicians destroy or ablate cardiac tissue to correct irregular heart rhythms. Researchers found that using advanced image-guided technology to more aggressively target diseased areas of the heart that cause arrythmias didn't lead to better outcomes for patients -- and put some at higher risk of strokes, according to new results.

Scientists identify a possible source for Charon's red cap

Posted: 21 Jun 2022 07:56 AM PDT

Scientists combined data from NASA's New Horizons mission with novel laboratory experiments and exospheric modeling to reveal the likely composition of the red cap on Pluto's moon Charon and how it may have formed. This first-ever description of Charon's dynamic methane atmosphere using new experimental data provides a fascinating glimpse into the origins of this moon's red spot as described in two recent articles.

How elliptical craters could shed light on age of Saturn's moons

Posted: 21 Jun 2022 07:56 AM PDT

A new study describes how unique populations of craters on two of Saturn's moons could help indicate the satellites' age and the conditions of their formation. Using data from NASA's Cassini mission, researchers have surveyed elliptical craters on Saturn's moons Tethys and Dione for this study.

Remote sensing helps track carbon storage in mangroves

Posted: 21 Jun 2022 07:56 AM PDT

Researchers have developed a model that can estimate the productivity of mangrove forests at large scales. A remote sensing-based productivity model that considered the effects of tidal inundation was developed. Comparisons with carbon measurements from carbon flux towers showed that the model was able to accurately estimate the productivity of mangrove forests in China. The results highlight the potential of this type of model for assessing the capacity of mangrove forests to store carbon.

Wildlife--human conflicts could shift with climate change

Posted: 21 Jun 2022 07:56 AM PDT

Researchers modeled the risk of human -- elephant conflict in Thailand under different climate change scenarios using a risk framework. A spatial shift in the risk of conflict was observed with climate change, with northern areas and higher latitudes showing increasing risk in the future. These results can be used to develop planning strategies in affected communities and increase coexistence awareness.

Sensor imperfections are perfect for forensic camera analysis

Posted: 21 Jun 2022 07:56 AM PDT

In a project aimed at developing intelligent tools to fight child exploitation, computer scientists have developed a system to analyze the noise produced by individual cameras. This information can be used to link a video or an image to a particular camera.

A blueprint for life forms on Mars?

Posted: 21 Jun 2022 07:56 AM PDT

Microbes taken from surface sediment near Lost Hammer Spring, Canada, about 900 km south of the North Pole, could provide a blueprint for the kind of life forms that may once have existed, or may still exist, on Mars.

Magnetic superstructures resonate with global 6G developers

Posted: 21 Jun 2022 06:14 AM PDT

Scientists have detected collective resonance at remarkably high and broad frequency bands. In a magnetic superstructure called a chiral spin soliton lattice (CSL), they found that resonance could occur at such frequencies with small changes in magnetic field strength. The findings suggest CSL-hosting chiral helimagnets as promising materials for future communication technologies.

Posted: 20 Jun 2022 05:49 PM PDT

Some people who experience heart failure have less biodiversity in their gut or have elevated gut metabolites, both of which are associated with more hospital visits and greater risk of death, according to a systematic review of research.

Who benefits from brain training and why?

Posted: 20 Jun 2022 09:23 AM PDT

If you are skilled at playing puzzles on your smartphone or tablet, what does it say about how fast you learn new puzzles, or, more broadly, how well you can focus, say, in school or at work? Or, in the language of psychologists, does 'near transfer' predict 'far transfer'? A team of psychologists has found that people who show near transfer are more likely to show far transfer.

Fifth of global food-related emissions due to transport

Posted: 20 Jun 2022 09:23 AM PDT

Food transport constitutes 19 percent of food emissions, equivalent to 6 percent of emissions from all sources. High-income countries are responsible for nearly half of these emissions, leading researchers to conclude that among the rich, eating locally should be prioritised.
