A research team in Ehime University prepared a new type of synthetic polymer, which can be degraded into a combination of well-defined low molecular weight compounds under very mild acidic conditions. The new polymer, poly(β-keto enol ether), has great potential to be utilized as an environmentally friendly material in the near future.
If scientists could give living cells magnetic properties, they could perhaps manipulate cellular activities with external magnetic fields. But previous attempts to magnetize cells by producing iron-containing proteins inside them have resulted in only weak magnetic forces. Now, researchers reporting in ACS' Nano Letters have engineered genetically encoded protein crystals that can generate magnetic forces many times stronger than those already reported.
Today, as world leaders gather for the UN General Assembly, hundreds of emerging leaders focused on fighting global inequality came together at the Bill & Melinda Gates Foundation's third annual Goalkeepers event in New York City.
Majorana bound states have attracted scientists' interests and topological superconductors (TSCs) are predicted to host exotic Majorana states that obey non-Abelian statistics and can be used to implement a topological quantum computer. Recently, experimental scientists provide strong evidences for the existence of Majorana zero-energy mode in vortex cores in single material platforms of Fe(Te,Se) bulk single crystals and similar compounds of iron-based superconductors.
This is the first study in the Mediterranean to combine boat and marina sampling data with crew surveys to better understand the role these boats play in spreading alien species. The researchers from the University of Pavia, Italy found that boats traveling to new marinas were likely to be transporting alien species in the biofouling: living growth on submerged areas of the vessel.
CORVALLIS, Ore. - Ocean-based actions have greater potential to fill in gaps in climate change mitigation than previously appreciated, an Oregon State University scientist and two co-authors explain in a paper published today in Science.
The article by OSU distinguished professor Jane Lubchenco and her collaborators aims to connect the dots between two new international reports, one highlighting the devastating impact of climate change on the ocean, the other an analysis of ocean-related solutions to climate change.
Osaka, Japan - Hydrogen occurs in nature as H2 molecules; however when deuterium isotopes—so called "heavy hydrogen"—are introduced, the result can be deuterium hydride (HD) or deuterium gas (D2). These compounds are useful starting materials in fine chemical production; however, the natural abundance of these gases is low and the techniques used for producing D2 are expensive and energy intensive. Researchers from Osaka University have now developed a catalyst that promotes selective production of D2 and HD from the inexpensive starting material formic acid in the presence of D2O.
Weeds are thieves. They steal nutrients, sunlight and water from our food crops. In the case of sugarcane, yield refers to the amount of biomass and the sucrose concentration of the cane, which ultimately determines the amount of sugar produced. Two weedy culprits, namely itchgrass and divine nightshade, reduce cane biomass and sucrose yield.
PITTSBURGH, Sept. 25, 2019 - The research community is increasingly recognizing video as more than just a medium to disseminate scientific findings after a study's conclusion. A powerful tool, film can engage study participants and become an integral part of the scientific process, when deployed thoughtfully.
To guide this emerging practice, University of Pittsburgh Graduate School of Public Health scientists performed the first review of studies on use of film in public health research, reporting their findings in the journal Qualitative Health Research.
Jackdaws can learn from each other to identify "dangerous" humans, new research shows.
The birds are known to recognise individual people, and respond differently to those they see as a threat.
In the new study, by the University of Exeter, a person unknown to the jackdaws approached their nest, and scientists played a recording of either a warning call or "contact calls" (suggesting no threat).
The next time the jackdaws saw this person, the birds that had heard the warning call reacted defensively by retuning more quickly to their nests.
