Vaccine passports/COVID passes: The best way of preventing another lockdown or a threat to civil freedoms and rights?

COVID passes may help prevent lockdowns, but experts warn of risks including segregation, surveillance, and economic barriers. Some researchers advocate for mandatory covid passes as a 'mechanism to target restrictions' and reduce cases, while others argue they introduce profound risks and can exacerbate existing inequalities.

Can eating alone be bad for your heart?

A recent study published by The Menopause Society suggests that eating alone may contribute to an increased risk of heart disease in older women. Older women who eat alone have poorer nutritional knowledge and intake, as well as a higher prevalence of angina, a type of chest pain caused by reduced blood flow to the heart.

Quantum Physics in Proteins

A new analytical technique combines quantum physics and molecular biology to track biomolecule changes in less than a trillionth of a second. By analyzing the collective movement of atoms, researchers were able to reduce 6000 dimensions to four and characterize conical intersections of quantum states in complex molecules.

100% renewable energy using building science

Researchers found that combining resource diversification, excess generation, building efficiency, and demand flexibility can reduce or eliminate long-duration energy storage in some regions. This approach enables the achievability of a fully renewable system with technology building blocks accessible today.

Social media is reshaping British universities’ value systems in a scramble for likes and shares

Researchers at the University of Cambridge found that universities are increasingly using social media metrics to claim impact in research, despite this being a 'naïve and problematic' grasp of the concept. This is linked to institutional isomorphism, where organisations imitate each other's approaches to uncertain goals.

Study: In much of the US, virtual school did not lower COVID-19 case rates in surrounding communities

A nationwide study of 895 US school districts found that opening schools for in-person learning did not increase COVID-19 case rates in surrounding communities, except in the South. The researchers controlled for local policies and community mobility data to analyze the impact of schools on community spread.

CO2 can be turned into a valuable resource

Researchers from the Paul Scherrer Institute found that CO2 electrolysis can produce formic acid, a promising product for various industries, but generates more CO2 than it consumes. The production process is commercially viable, but depends on a renewable energy mix to have a positive climate effect.

Restoring normal sleep reduces amyloid-beta accumulation in mouse model of Alzheimer’s disease

In a mouse model of Alzheimer's disease, researchers found that restoring normal sleep reduced amyloid-beta plaque accumulation. The thalamic reticular nucleus played a previously unsuspected role in symptoms associated with Alzheimer's, and its restoration could be a potential therapeutic approach.
