New study calls for mitigation, monitoring of common grease-proofing food packaging chemicals

Added: 08.11.2021 22:23 | 203 views | 0 comments

A scientist is calling for a better understanding of the health ramifications of ubiquitous 'grease proofing' chemicals that have been used for decades. A new study based on a symposium involving scientists at public and private institutions strikes an urgent tone on the need for new and better ways to detect and mitigate this class of chemical compounds, collectively known as per- and polyfluoroalkyl substances.

How bacteria create a piggy bank for the lean times: Basic science discovery could lead to improved biomaterial production

Added: 08.11.2021 22:23 | 184 views | 0 comments

Bacteria can store extra resources for the lean times. It's a bit like keeping a piggy bank or carrying a backup battery pack. One important reserve is known as cyanophycin granules, which were first noticed by an Italian scientist about 150 years ago. He saw big, dark splotches in the cells of the blue-green algae (cyanobacteria) he was studying without understanding either what they were or their purpose. Since then, scientists have realized that cyanophycin was made of a natural green biopolymer, that bacteria use it as a store of nitrogen and energy, and that it could have many biotechnological applications.

Molecular mixing creates super stable glass

Added: 08.11.2021 22:23 | 200 views | 0 comments

Researchers have succeeded in creating a new type of super-stable, durable glass with potential applications ranging from medicines, advanced digital screens, and solar cell technology. The study shows how mixing multiple molecules -- up to eight at a time -- can result in a material that performs as well as the best currently known glass formers.

Smoke from nuclear war would devastate ozone layer, alter climate

Added: 08.11.2021 22:23 | 193 views | 0 comments

The massive columns of smoke generated by a nuclear war would alter the world's climate for years and devastate the ozone layer, endangering both human health and food supplies, new research shows. The international study draws on newly developed computer climate modeling techniques to paint an even grimmer picture of a global nuclear war's aftermath than previous analyses.

Longstanding magnetic materials classification problem solved

Added: 08.11.2021 22:23 | 190 views | 0 comments

For over 100 years, physicists, chemists, and materials scientists have developed extensive theoretical and experimental machinery to predict and characterize the electronic properties of magnetic materials, but even the most successful classification system, developed almost 75 years ago by Lev Shubnikov, was incomplete. An international team of researchers announced this week that it has finally been completed.

Chemists discover faster-acting forms of insecticide imidacloprid

Added: 08.11.2021 22:23 | 204 views | 0 comments

Scientists have developed seven crystal forms of imidacloprid -- one of the world's most widely used insecticides -- in an effort to sharply reduce its environmental impact. The new forms work up to nine times faster than the original version, meaning a smaller amount can be used to control insects like infectious disease-transmitting mosquitoes, while reducing the chance of harm to other organisms, such as bees.

A rare feat: Material protects against both biological and chemical threats

Added: 08.11.2021 22:23 | 198 views | 0 comments

Researchers have developed a versatile composite fabric that can deactivate both biological threats, such as the novel coronavirus that causes COVID-19, and chemical threats, such as those used in chemical warfare. A material that is effective against both classes of threats is rare. The new material also is reusable. It can be restored to its original state after the fabric has been exposed to threats by a simple bleach treatment.

How mussels make a powerful underwater glue

Added: 08.11.2021 22:23 | 191 views | 0 comments

Blue mussels (Mytilus edulis) spend their days being buffeted by crashing waves. They manage to stay tethered to the rocks or their fellow mussels thanks to a highly effective underwater glue they produce. Because achieving adhesion in the presence of water is so challenging, scientists who are interested in producing effective adhesives for use in wet environments (e.g., for surgical or dental treatments) have turned to mussels for inspiration. After a decade of work in the area, a team has succeeded in uncovering the cellular mechanisms by which mussels fabricate underwater adhesives.
