The Ethics of Developing COVID-19 Treatments and Vaccination
CMU's experts explore the options Researchers and doctors around the world are in a race to save lives, not only through caring for patients sick with COVID-19, but in the hunt to discover an effective treatment or vaccine. In the rush to do science quickly, Carnegie Mellon University ethicist Alex John London says it is easy to make mistakes.

Antibiotic matter waves
Antibiotic matter waves
One of the central tenets of quantum mechanics is the wave-particle duality. It tells us that even massive objects behave like both particles and waves. A number of previous experiments have shown this for electrons, neutrons, atoms and even large molecules. Quantum theory maintains that this is a universal property of matter.

False memories of crime appear real when retold to others
People are no better than chance at identifying when someone else is recounting a false or real memory of a crime, according to a new UCL study. The findings, published in Frontiers in Psychology , build on a previous study that was the first to successfully implant false memories of committing a crime - involving either assault or assault with a weapon that resulted in police contact.

When Maxwell's demon takes its time
When Maxwell’s demon takes its time
Researchers at the Universities Vienna and Stuttgart have investigated a version of Maxwell's demon embodied by a delayed feedback force acting on a levitated microparticle. They confirmed new fundamental limits that time delay imposes on the demon's actions which are not covered by the standard laws of thermodynamics.

University of Minnesota Twin Cities designs respirator mask prototypes from filter technology
The need for N95 masks has skyrocketed in recent weeks in response to COVID-19. To address this challenge, an interdisciplinary research team at the University of Minnesota Twin Cities has designed two respirator mask prototypes from donated filter material by Cummins and bendable components from Bedford Industries.  The masks - one modified anesthesia mask and one single-use, disposable mask - are being developed to be close to a N95-equivalent with three distinctive components in mind: ventilation, fit and resilience to supply chain fluctuations.

Red wine component mimics oestrogen to support healthy ageing
Some dietary compounds such as resveratrol, which is commonly found in red wine, can mimic oestrogen to activate anti-ageing proteins called sirtuins, finds a new UCL study.

Saturn's 'energy crisis' solved with data from Cassini's final mission
Saturn’s ’energy crisis’ solved with data from Cassini’s final mission
Data gathered by the Cassini spacecraft during the final months of its mission show why Saturn's upper atmosphere is much hotter than expected. Scientists have long wondered why Saturn's upper atmosphere is hotter than would be expected by heating from the Sun alone - a conundrum dubbed Saturn's ‘energy crisis'.

Open science in the era of COVID-19
Science moving forward without traditional forms of peer review could shorten the path to solutions - but it also increases the chances that low-quality science gets overhyped. Usually, if biomedical researchers want to publish in a high-quality journal, their research must first withstand review by several outside experts.

Stronger Atlantic currents drive temperate species to migrate towards the Artic Ocean
Stronger Atlantic currents drive temperate species to migrate towards the Artic Ocean
The Arctic Ocean increasingly resembles the Atlantic, not only regarding its temperature but also the species that live there. However, scientists from the CNRS and Université Laval, Quebec 1 showed that an unprecedented strengthening of Atlantic currents is playing a major role in this phenomenon called 'Atlantification'.

AI techniques used to improve battery health and safety
AI techniques used to improve battery health and safety
Researchers have designed a machine learning method that can predict battery health with 10x higher accuracy than current industry standard, which could aid in the development of safer and more reliable batteries for electric vehicles and consumer electronics. The researchers, from Cambridge and Newcastle Universities, have designed a new way to monitor batteries by sending electrical pulses into them and measuring the response.

Memory cells that help us interpret new situations
Memory cells that help us interpret new situations
Neurons that store abstract representations of past experiences are activated when a new, similar event takes place. Imagine you are meeting a friend for dinner at a new restaurant. You may try dishes you haven't had before, and your surroundings will be completely new to you. However, your brain knows that you have had similar experiences - perusing a menu, ordering appetizers, and splurging on dessert are all things that you have probably done when dining out.

Insect wings hold antimicrobial clues for improved medical implants
Insect wings hold antimicrobial clues for improved medical implants
U sing a range of advanced imaging tools, functional assays and proteomic analyses , a study by the University of Bristol has identified new ways in which nanopillars can damage bacteria. These important findings will aid the design of better antimicrobial surfaces for potential biomedical applications such as medical implants and devices that are not reliant on antibiotics.

Making Biofuels Cheaper by Putting Plants to Work
Making Biofuels Cheaper by Putting Plants to Work
Biofuels are an important part of the broader strategy to replace petroleum-based gasoline, diesel, and jet fuels that we use today. However, biofuels have so far not reached cost parity with conventional petroleum fuels. One strategy to make biofuels more competitive is to make plants do some of the work themselves.

U-M engineers work to disinfect N95 masks for frontline medical personnel
The N95 respirator mask is, for many medical care professionals, the first line of defense against COVID-19 and dwindling supplies are one of the biggest threats to health systems during this pandemic. University of Michigan engineers are working quickly to address the shortage by developing efficient, effective and scalable ways to disinfect masks, which are typically discarded after one use.

Common coronaviruses are highly seasonal, with most cases peaking in winter months
Four types of human coronaviruses that cause common respiratory infections are sharply seasonal and appear to transmit similarly to influenza in the same population, according to a new study by University of Michigan School of Public Health researchers. The authors of the study, published as a preprint in the Journal of Infectious Diseases, say it's not possible to tell whether the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19 also behaves like this but hope their findings will help better prepare for what's yet to come in the pandemic.

Synthesizing sugars: U-M chemists develop method to simplify carbohydrate building
Carbohydrates are complex molecules, difficult to synthesize in the lab, but doing so is useful in studying beneficial sugars such as those found in human breast milk, or enabling researchers to tailor the chemical structure of drug candidates, vaccines and natural products. University of Michigan chemists have developed a simple method of synthesizing carbohydrates that widens the range of labs that can use synthetic chemistry to generate and study novel carbohydrate structures.

How the chemical industry can meet the climate goals
How the chemical industry can meet the climate goals
ETH researchers analysed various possibilities for reducing the net CO2 emissions of the chemical industry to zero. Their conclusion? The chemical industry can in fact have a carbon-neutral future. Switzerland's Federal Council has decided that the country should become carbon-neutral by 2050. This may be challenging as far as car traffic and the entire power sector are concerned, but not impossible - with systematic electrification and the exclusive use of carbon-neutral energy sources, for example.

School closures play marginal role in containing COVID-19 but are key to restarting society
School closures do not appear to have a significant effect on the spread of infections during coronavirus outbreaks such as COVID-19 but will be crucial to how we restart society after lockdown, according to a new study led by UCL. The systematic review, published today in The Lancet Child & Adolescent Health,  is the first study to look at the evidence and emerging data on the benefit of school closures and other school social distancing interventions in outbreaks such as SARS, MERS and COVID-19.
