Chemistry
We summarize the week's scientific breakthroughs every Thursday.
- Physics
Can room-temperature superconductors work without extreme pressure?
The next generation of materials that conduct electricity with no resistance could shrug off the need for high pressure and low temperatures.
- Earth
Phosphorus for Earth’s earliest life may have been forged by lightning
Lightning strikes can supply one of life’s essential elements, long thought to be delivered by meteorites billions of years ago.
- Quantum Physics
‘Designer molecules’ could create tailor-made quantum devices
Scientists are making molecules suited to a variety of quantum tasks by building them up, atom by atom.
- Chemistry
Chemists are reimagining recycling to keep plastics out of landfills
Recycling plastics is really hard, and usually creates low-quality materials that aren’t good for much. Chemists are trying to change that.
- Chemistry
This weird chemical bond acts like a mash-up of hydrogen and covalent bonds
Chemistry students are taught that hydrogen bonds and covalent bonds are distinct, but a new study shows they exist on a continuum.
- Chemistry
Zinc-air batteries are typically single-use. A new design could change that
Swapping out the electrolyte in zinc-air batteries helps these next-gen power sources last longer.
- Earth
Plastic drinking water pipes exposed to high heat can leak hazardous chemicals
Lab tests exposing commonly used water pipes to wildfire-like heat show damaged pipes can leach the carcinogen benzene and other chemicals.
- Chemistry
A new iron-based catalyst converts carbon dioxide into jet fuel
Jet fuel made from carbon dioxide could one day reduce pollution from air travel.
- Planetary Science
50 years ago, scientists caught their first glimpse of amino acids from outer space
In 1970, scientists detected amino acids in a meteorite. Fifty years later, a variety of chemical ingredients for life have been found in other space rocks.
- Physics
Supercooled water has been caught morphing between two forms
A new experiment used ultrafast techniques to reveal high-density water transforming into low-density water at subfreezing temperatures.
- Chemistry
A new portable device can reveal a chili pepper’s heat
The “Chilica-pod” measures levels of the fiery capsaicin compound in peppers.
- Chemistry
Heating deltamethrin may help it kill pesticide-resistant mosquitoes
A simple chemical trick creates a much faster-acting form of a common insecticide, which could help fight malaria and other mosquito-borne illnesses.
