The lithium batteries that power our electronic devices and electric vehicles have a number of drawbacks. The electrolyte is a flammable liquid and the lithium they're made of is a limited resource. Specialists have now developed a non-flammable, solid electrolyte that operates at room temperature. It transports sodium - which is found everywhere on earth - instead of lithium.
Age and likelihood of SARS-CoV-2 infection

Scientists have estimated that the age of an individual does not indicate how likely they are to be infected by SARS-CoV-2. However, development of symptoms, progression of the disease, and mortality are age-dependent.
Scientists engineer bacteria-killing molecules from wasp venom

Scientists have engineered powerful new antimicrobial molecules from toxic proteins found in wasp venom. The team hopes to develop the molecules into new bacteria-killing drugs, an important advancement considering increasing numbers of antibiotic-resistant bacteria.
Carnivores living near people feast on human food, threatening ecosystems
- ScienceDaily
- 20/10/12 22:42
Ecologists have found that carnivores living near people can get more than half of their diets from human food sources, a major lifestyle disruption that could put North America's carnivore-dominated ecosystems at risk.
Sharp rise in natural disasters in last 20 years, Asia hardest hit, UN says
There has been a dramatic increase in extreme weather events in the past 20 years, which are taking a heavy human and economic toll worldwide and are on track to expand further, and Asia has been hardest-hit, the United Nations said on...
Using robotic assistance to make colonoscopy kinder and easier
- ScienceDaily
- 20/10/12 21:20
Scientists have made a breakthrough in their work to develop semi-autonomous colonoscopy, using a robot to guide a medical device into the body. The milestone brings closer the prospect of an intelligent robotic system being able to guide instruments to precise locations in the body to take biopsies or allow internal tissues to be examined.
Chemists create new crystal form of insecticide, boosting its ability to fight mosquitoes and malaria
- ScienceDaily
- 20/10/12 21:20
Through a simple process of heating and cooling, researchers have created a new crystal form of deltamethrin -- a common insecticide used to control malaria -- resulting in an insecticide that is up to 12 times more effective against mosquitoes than the existing form.
COVID-19 antibodies last at least three months; so do symptoms for many
People infected with COVID-19 develop antibodies targeting the new coronavirus that last for at least three months, according to two reports published on Thursday in Science Immunology. The two studies, together involving nearly 750 patients, both point to immunoglobulin G (IgG) antibodies, which start showing up well after an infection begins, as the longest-lasting. Researchers found IgG...
Tighter border policies leave migrants vulnerable to effects of climate change
As the planet continues to warm, people living in the world's most vulnerable regions—like arid or low-lying nations—must contend with the decision to stay in a place where livability is decreasing or leave for countries with more stable climate and economic conditions.
Carnivores living near people feast on human food, threatening ecosystems
Ecologists at the University of Wisconsin-Madison have found that carnivores living near people can get more than half of their diets from human food sources, a major lifestyle disruption that could put North America's carnivore-dominated ecosystems at risk. The researchers studied the diets of seven predator species across the Great Lakes region of the U.S. They gathered bone and fur samples for...
