Embed Germ Defence behaviours at home to reduce virus spread now and in the future
As COVID-19 vaccines are rolled out, a roadmap for unlocking Britain is announced, new research which looked at data from over 28,000 users of the website 'Germ Defence' since May 2020 highlights the continued, critical importance of breaking chains of virus transmission within our homes.

Light-emitting tattoo engineered for the first time
Scientists at UCL and the IIT -Istituto Italiano di Tecnologia (Italian Institute of Technology) have created a temporary tattoo with light-emitting technology used in TV and smartphone screens, paving the way for a new type of "smart tattoo" with a range of potential uses. The technology, which uses organic light-emitting diodes (OLEDs), is applied in the same way as water transfer tattoos.

TOPMed: Analyzing human genomes to understand mutations, human evolution
What kind of questions would you ask if you had access to the full DNA makeup of tens of thousands of people? Would you look for disease-causing mutations? Would you be curious about how modern humans are related? Those are some of the issues that researchers are studying as part of a project called TOPMed, the Trans-Omics for Precision Medicine Program.

Menthol cigarettes linked to 10 million extra smokers, hundreds of thousands of premature deaths
Menthol cigarettes contributed to 378,000 premature deaths in the United States between 1980 to 2018, according to a new University of Michigan study. The research shows that about 10 million smokers were attributable to menthol cigarettes, which researchers estimate accounted for about 3 million life years lost.

Opioid agonist treatment could substantially reduce drug related deaths if used more widely
New evidence that opioid agonists such as methadone and buprenorphine could substantially reduce drug related deaths if more widely used in the community and prison, and for longer, has been published in Lancet Psychiatry today [25 February]. Treatment of people addicted to opioids with methadone or buprenorphine also known as 'opioid agonist treatment' (OAT) reduces many of the harms associated with injecting drug use including death by overdose, suicide, injury, or other causes.

New Coronavirus Toolkit allows for ’open access’ of antibodies and genetic tools to further global research into COVID-19 variants
An international consortium, led by scientists in Scotland, have devised a Coronavirus Toolkit which gives researchers from across the world open access to materials, including antibodies and genetic tools, which can be easily and immediately ordered via an online portal - to further research into COVID-19.

Forests' long-term capacity to store carbon is dropping in regions with extreme annual fires
Forests’ long-term capacity to store carbon is dropping in regions with extreme annual fires
Researchers have analysed decades' worth of data on the impact of repeated fires on ecosystems across the world. Their results, published today in the journal Nature Ecology and Evolution , show that repeated fires are driving long-term changes to tree communities and reducing their population sizes.

Artificial 'brain' reveals why we can't always believe our eyes
Artificial ’brain’ reveals why we can’t always believe our eyes
A computer network closely modelled on part of the human brain is enabling new insights into the way our brains process moving images - and explains some perplexing optical illusions. It's very hard to directly measure what's going on inside the human brain when we perceive motion - even our best medical technology can't show us the entire system at work.

Green fuels for aviation
Green fuels for aviation
Researchers at the Paul Scherrer Institute PSI and the partner institute Empa have started a joint initiative called SynFuels. The goal is to develop a process for producing kerosene from renewable resources. In this way liquid fuel mixtures of the highest quality, which would allow the most residue-free combustion possible and thus be suitable for aircraft propulsion, should be obtainable using carbon dioxide and hydrogen from renewable resources.

Genetic treatment extends fruit fly lifespan and prevents Alzheimer’s damage
Modifying brain cell activity can extend the lifespan of fruit flies while also preventing the damage characteristic of Alzheimer's disease, finds a new study led by UCL researchers. The researchers found that by modifying the levels of two different proteins that are active in two different types of brain cells, they could extend fruit fly lifespans by around 7-9% (close to an extra week), they report in PNAS.

Smartphones could help to prevent glaucoma blindness - study
Smartphones could help to prevent glaucoma blindness - study
Smartphones could be used to scan people's eyes for early-warning signs of glaucoma - helping to prevent severe ocular diseases and blindness, a new study reveals. Some of the most common eye-related diseases are avoidable and display strong risk factors before onset, but it is much harder to pinpoint a group of people at risk from glaucoma.

Copepods can find mates even in turbulent conditions
Copepods can find mates even in turbulent conditions
Copepods (minute crustaceans with paddle-like feet) can differentiate between disturbances in water generated by nearby organisms and turbulence caused by wind or waves - an ability which helps them to find mates. It had previously been assumed that turbulent conditions would impede the quest for mates.

New insights into the mechanism of nuclear fission
New insights into the mechanism of nuclear fission
Nuclear physicists at the University of Cologne have contributed to an international research collaboration to show the way the spin of the two fragments, resulting from the splitting of an atomic nucleus, is generated / publication in Nature A series of experiments at the ALTO particle accelerator facility in Orsay, France, has revealed that the fragments resulting from nuclear fission obtain their intrinsic angular momentum (or spin) after fission, not before, as is widely assumed.

Earth’s Gulf Stream System at its weakest in over a millennium 
A new study involving researchers from UCL has found consistent evidence of a decline in ocean currents, with the Gulf Stream System, also known as the Atlantic Meridional Overturning Circulation (AMOC), at its weakest in over 1,000 years.

Light-twisting ’chiral’ nanotechnology could accelerate drug screening
In a new drug screening technique that relies on gold nanorods to twist light, a red glow can signal the failure of a medication being designed to treat "amyloid” diseases such as Type II diabetes and pancreatic cancer. The technique was developed by researchers from the University of Michigan, Jilin University in China and the Federal University of São Carlos in Brazil.

Prioritizing oldest for COVID-19 vaccines saves more lives, years of life
On Dec. 8 in Coventry, England, Margaret Keenan, 90, became the first patient in the U.K. to receive the Pfizer COVID-19 vaccine. (AP photo by Jacob King) Challenging the idea that older people with shorter life expectancies should rank lower in coronavirus immunization efforts, new UC Berkeley research shows that giving vaccine priority to those most at risk of dying from COVID-19 will save the maximum number of lives, and their potential or future years of life.

Using Submarine Cables to Detect Earthquakes
Seismologists at Caltech working with optics experts at Google have developed a method to use existing underwater telecommunication cables to detect earthquakes. The technique could lead to improved earthquake and tsunami warning systems around the world. A vast network of more than a million kilometers of fiber optic cable lies at the bottom of Earth's oceans.

For first time, researchers send entangled qubit states through a communication channel
In a breakthrough for quantum computing, University of Chicago researchers have sent entangled qubit states through a communication cable linking one quantum network node to a second node. The researchers, based in the Pritzker School of Molecular Engineering at the University of Chicago, also amplified an entangled state via the same cable first by using the cable to entangle two qubits in each of two nodes, then entangling these qubits further with other qubits in the nodes.
