Smaller plates help reduce food waste in campus dining halls

A University of Illinois study found that shifting from round to oval plates with smaller surface areas can significantly reduce food waste in dining halls. The researchers observed significant reductions in food selection, consumption, and waste when diners used the oval plates, resulting in nearly 20 grams less food waste per plate.

Scientists probe electronic angular momentum to a chemical reaction for the first time

Researchers have successfully probed electronic angular momentum to a chemical reaction at the quantum state-resolved level, offering a detailed understanding of molecular crossed beam experiments and theoretical simulations. This breakthrough reveals subtle influences of electronic angular momentum on chemical product distributions.

Could post-COVID-19 tourists become less adventurous?

Research found that post-pandemic tourism is influenced by a behavioral immune system, leading to increased nationalism, xenophobia, and avoidance of crowds. Tourists may choose familiar destinations over new ones, increasing destination loyalty. This could have long-term implications for businesses during the COVID-19 era.

Theory could accelerate push for spintronic devices

Rice University scientists develop a new theory that can help identify materials for advanced spintronic devices, which depend on electron spin states. The theory predicts heteropairs of two-dimensional bilayers that enable large Rashba splitting, making room-temperature spin transistors possible.

Openly available toolkit to help lab-based coronavirus research

A new, openly available SARS-CoV-2 laboratory research toolkit was published in PLOS Biology. The toolkit includes a 'single plasmid reverse genetics' system allowing researchers to manipulate the coronavirus genome and study individual mutations. This will fast-track investigation of COVID-19 research, including novel variants, drug d...

A tangled food web

The study argues that trophic levels are insufficient to assess aquaculture sustainability due to changing feed compositions and energy requirements. Researchers advocate for more nuanced assessments, such as voluntary certifications and incentives for environmentally responsible practices.

Development of an electroceutical to drastically reduce high-risk, preterm labor

A non-invasive electroceutical developed to detect early preterm labor and suppress uterine contractions. The device uses a donut-shaped electrode inserted into the cervix to sense signals of uterine contractions, providing a potential breakthrough in preventing premature birth.

Scientists investigated more thoroughly Walker breakdown in 3D magnetic nanowires

Scientists studied how the cross-sectional geometry of 3D nanowires affects domain wall dynamics and Walker breakdown phenomenon. The research found that oscillatory behavior can be explained by energy changes due to deformation during rotation, promising new possibilities for nano-oscillators and radiofrequency electromagnetic radiation.

European unions' support varies for precarious workers

A recent study by Cornell University researchers found that European unions have been practicing solidarity in many cases, improving working conditions for peripheral workers. In contrast, some unions have adopted a dualist approach, prioritizing their own members' interests over those of non-unionized workers.
