Making disorder for an ideal battery
- ScienceDaily
- 20/10/12 23:13
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
- ScienceDaily
- 20/10/12 23:13
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
- ScienceDaily

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...
Chemists create new crystal form of insecticide, boosting its ability to fight mosquitoes and malaria
p>Through a simple process of heating and cooling, New York University 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.
Scientists engineer bacteria-killing molecules from wasp venom
A team led by scientists in the Perelman School of Medicine at the University of Pennsylvania has 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 which can cause illness such as sepsis and...
Tetrahedra may explain water's uniqueness
Researchers at the Institute of Industrial Science at the University of Tokyo sifted through experimental data to probe the possibility that supercooled water has a liquid-to-liquid phase transition between disordered and tetrahedrally structured forms. They found evidence of a critical point based on the cooperative formation of tetrahedra, and show its minor role in water's anomalies. This work...
WHO chief says herd immunity approach to pandemic 'unethical'
Tedros Adhanom Ghebreyesus cites lack of understanding of virus and lasting health effectsCoronavirus – latest updatesSee all our coronavirus coverageThe head of the World Health Organization has warned against deliberately allowing coronavirus to spread in the hope of achieving so-called herd immunity, saying the idea is unethical.“Herd immunity is a concept used for vaccination, in which a...
Climate change spurs doubling of disasters since 2000: UN
Climate change is largely to blame for a near doubling of natural disasters in the past 20 years, the United Nations said on Monday.
DC charters offer innovations in pandemic-era education
Returning to school in the nation's capital during the pandemic has proven to be an ongoing experiment in learning—and not just for students.
Russia shuns US lunar program, as space cooperation under threat
Russia is unlikely to participate in the Moon-orbiting station planned by the United States, a Russian official said Monday, marking the probable end of the type of close cooperation seen for two decades on the International Space Station (ISS).

As genome-editing trials become more common, informed consent is changing
- ScienceDaily
- 20/10/12 19:20
As public interest and expanded research in human genome editing grows, many questions remain about ethical, legal and social implications of the technology. People who are seriously ill may overestimate the benefits of early clinical trials while underestimating the risks. This makes properly understanding informed consent, the full knowledge of risks and benefits of treatments, especially...
