Infinitely recyclable plastic is possible, but it needs to be cheaper. (AP Photo/Richard Vogel)A new type of plastic that can be recycled over and over again has the potential to help reduce the staggering amount of plastic waste that is crammed into landfills and pollutes the environment, but researchers recommend tweaking production processes to make the material cheaper and more environmentally friendly.

Color-tunable LED aims to reduce screens' blue light, improve image quality. (Unsplash/Victoria Heath)Physicists have invented a novel LED chip that could effectively glow in any tone, in contrast with other models that require mixing together a trinity of colors — red, green and blue — to form a spectrum of shades.

Going short on sleep in middle age raises your dementia risk. (Pixabay/12122)A new analysis of longitudinal data from British adults revealed that those who sleep less than seven hours per night during middle age are at an increased risk of developing dementia once they reach 70 years old, highlighting the importance of good sleep habits throughout adulthood.

Hong)Inspired by the conviction of music producer Phil Spector for the 2003 murder of Lana Clarkson, researchers have discovered that when a gun is fired, gas from the muzzle escapes in a series of turbulent vortex rings that can cause blood spatter to reverse direction, splattering away from the shooter instead of toward them.

Kids who interact with CPS, even if there's no finding of abuse, are more likely to commit suicide. (Unsplash/Michal Parzuchowski)Children with any level of child protective services involvement had three times the odds of dying by suicide — a new finding that highlights the need for more robust supportive services and mental health care, even for children whose abuse is not confirmed.

Companies located in pro-Trump states revealed less environmental impact info. (AP Image/Czarek Sokolowski)Companies headquartered in states that voted solidly for Donald Trump shared significantly less information about their potential impact and exposure to climate change following the 2016 presidential election than prior to Trump's surprise victory, according to new research analyzing corporate social responsibility reports.

Daily pot use can have some distinctly non-therapeutic effects, according to a new study.  (AP Photo/Seth Wenig)People who use marijuana daily could be more likely to see hallucinations and have other psychotic experiences earlier in life, according to new research that strengthens our understanding of genetic vulnerabilities, environmental factors and the risk of schizophrenia among cannabis consumers.

A South Korean study showed many parents would be OK with robots taking over certain aspects of child care. (AP Photo/Vincent Yu)Autonomous social robots are designed for human communication and interaction, but are humans ready to integrate them into daily life? A South Korean study has revealed that working parents are open to the idea of using social robots in child care functions such as socialization, entertainment and consultation, but they are less interested in using them for educational purposes with their kids.

This decade will be a make-or-break point for the space junk problem. (Pixabay/WikiImages)So much debris from past missions has accumulated in low Earth orbit that between one-third and half of the zone’s capacity to sustain long-term space activities has already been filled, scientists have reported.

Children who have been spanked show reactions to threats similar to those who've experienced worse trauma. (Unsplash/Marcos Paulo Prado)In what is apparently the first investigation to look at the neuronal effects of spanking alone rather than its effects when accompanied by other kinds of physical punishment, researchers found that children who had been spanked showed greater brain activity after being exposed to threatening stimuli than those who had never been spanked, closely mirroring a pattern seen in children who have experienced more severe forms of maltreatment.

Increasing salinity in fresh water causes more bacteria to be released into the air. (AP Photo/Julio Cortez)Increasing the saltiness of freshwater changes the number and types of bacteria that are launched into the air by breaking waves and bursting bubbles, which could have implications for the risk that people will be exposed to toxins from harmful algal blooms in the future.

Robotic earthworms might be human helpers in the near future. (AP Photo/Dean Fosdick)Inspired by the efficient behavior of insect muscles, researchers have developed tiny electrostatic actuators that could have wide-ranging applications in robotics. Their innovations include earthworm-scale robots designed to inspect tight spaces, such as the inside of aircraft engines or dangerous debris fields.

How we perceive colors unlocks other mysteries about the brain. (Brain and Cognition Lab, University of Oxford)In research powered by machine learning, scientists found it is possible to tell which color someone is seeing by monitoring their brain activity, independent of their words for that color, adding to our understanding of how memories are formed and helping researchers better "decode" the specific features they contain.

Posture can affect memory, according to this study. (Unsplash/Michal Parzuchowski)People who cross their hands behind their back when learning new sentences are less likely to remember action verbs, nouns and sentences, but their memory of visual verbs is not influenced, according to new research from scientists in Spain, France and Italy.
