Long Island measurements reveal household products and buildings as major summer pollution sources

phys.org

Products such as hairspray, paint and household disinfectants are increasingly causing summertime air pollution—and cities aren't accounting for it, which makes it harder to issue air quality advisories and enact regulations, new research…

Hawaiian hot spot study uncovers evidence of true polar wander

phys.org

On Earth, everything is moving. The planet spins, the tectonic plates shift and the spin axis wobbles, as do the magnetic poles, which makes determining how things move a rather tricky proposition. For Rice University's Richard Gordon,…

'Self-blinking dyes' simplify nanoscale imaging without sacrificing precision

phys.org

Nanobodies are extremely small antibody fragments that bind to specific molecules. When nanobodies are labeled with dyes, they can be used as probes to enhance super-resolution microscopy. However, conventional blinking dyes often perform…

Undergraduate student may have solved puzzle regarding isolated galaxies that have stopped producing stars

phys.org

An undergraduate astrophysics student at UC Berkeley has found three unusual galaxies—cataloged as Shapiro Dwarf Galaxies I, II and III. Each galaxy is far from other galaxies and has stopped making stars, a combination that is extremely…

New polystyrene uses 50% plant-based material and breaks into fragments for potential recycling

phys.org

Polystyrene is used in protective packaging for televisions and electronic devices, in decorative boards and baseboards for interior construction, and in petri dishes. It is one of the world's most important plastics, with nearly 20…

First global genome atlas reveals overlooked microscopic life in hundreds of lakes and reservoirs

phys.org

Tiny single-celled organisms help keep lakes clear, but some can also contaminate the water. An international research team has analyzed DNA data from 362 lakes to create the first global genome atlas of these organisms. With the findings…

Giant tortoises outnumber people in Seychelles, with nearly 183,000 on Aldabra

phys.org

A landmark survey of the world's largest free-roaming giant tortoise population has revealed that the once-endangered species is thriving and stable in the Seychelles.

Acoustic experiments confirm topology can persist at gapless critical points

phys.org

Two studies on critical topology have recently been published in the journal Nature. These studies were led by the teams of Prof. Baile Zhang at Nanyang Technological University, Singapore, and Prof. Jianhua Jiang at the University of…

New display technology combines record brightness with pixels that stretch like rubber

phys.org

A research team led by Professor Jiwoong Yang of the Department of Energy Science and Engineering at DGIST has developed the world's first foundational technology for an ultrahigh-resolution stretchable quantum dot display (QLED) that can…

Use of natural gas or propane in commercial kitchens exposes workers to air pollution and dangerous heat
