When light and atoms share a common vibe
Scientists from EPFL, MIT, and CEA Saclay demonstrate a state of vibration that exists simultaneously at two different times. They evidence this quantum superposition by measuring the strongest class of quantum correlations between light beams that interact with the vibration. An especially counter-intuitive feature of quantum mechanics is that a single event can exist in a state of superposition - happening bothhere andthere , or bothtoday andtomorrow .

New blood-test device monitors blood chemistry continually
New blood-test device monitors blood chemistry continually
The new device can continuously sense levels of virtually any protein or molecule in the blood. The researchers say it could be transformative for disease detection, patient monitoring and biomedical research. For even the most routine of medical checkups, a blood test is often the first order of business.

TESS dates an ancient collision with our galaxy
TESS dates an ancient collision with our galaxy
A single bright star in the constellation of Indus, visible from the southern hemisphere, has revealed new insights on an ancient collision that our galaxy the Milky Way underwent with another smaller galaxy called Gaia-Enceladus early in its history. An international team of scientists led by the University of Birmingham adopted the novel approach of applying the forensic characterisation of a single ancient, bright star called ν Indi as a probe of the history of the Milky Way.

Emotional headlines have an impact regardless of the credibility of the source
New HU study on the influence of "fake news" on the brain Neurocognitive studies by researchers at the Humboldt-Universität zu Berlin (HU) show that headlines with emotional content influence our judgments about other people even when we consider the media source to be untrustworthy. Rumours, half-truths and misinformation can be consumed and shared non-stop online and have an enormous reach.

Brain Stem Cells Divide over Months
Brain Stem Cells Divide over Months
For the first time, scientists at the University of Zurich have been able to observe stem cells in the adult mouse brain that divide over the course of several months to create new nerve cells. The study shows that brain stem cells are active over a long period, and thus provides new insights for stem cell research.

Climate change: threshold for dangerous warming will likely be crossed between 2027-2042
The threshold for dangerous global warming will likely be crossed between 2027 and 2042 - a much narrower window than the Intergovernmental Panel on Climate Change's estimate of between now and 2052. In a study published in Climate Dynamics , researchers from McGill University introduce a new and more precise way to project the Earth's temperature.

New mechanism of force transduction in muscle cells discovered
New mechanism of force transduction in muscle cells discovered
Researchers of Münster University reveal mechanobiological function of muscle-specific adhesion protein / Study published in "Nature Communications" The ability of cells to sense and respond to their mechanical environment is critical for many cellular processes but the molecular mechanisms underlying cellular mechanosensitivity are still unclear.

A step toward understanding why COVID-19 boosts stroke risk
A UCLA-led study may help explain how COVID-19 increases the risk for stroke. Scientists made the finding by running fluid spiked with a COVID-19-like protein through a 3D-printed model of the arteries of a patient who had suffered a stroke. Although COVID-19 was first identified by its severe respiratory symptoms, the virus has caused strokes in young people who had no known risk factors.

New app to monitor Parkinson’s progression at home
A new smartphone app developed by researchers at UCL and Birkbeck, University of London, is enabling doctors to remotely monitor their patients' progression of Parkinson's symptoms, as reported in a new clinical trial. The findings, published in npj Parkinson's Disease , show that the app can provide clinicians with a more complete picture of a person's condition than they can get from a typically brief medical check-up.

A weather station for epilepsy
A weather station for epilepsy
To do this, Baud collaborated with Vikram Rao, neurologist at UCSF, to obtain neuronal activity data collected over several years using devices implanted long-term in the brains of patients with epilepsy. After confirming that there were indeed cycles of cerebral epileptic activity, the scientists turned their attention to statistical analysis.

Triaxial testing facility: Transition rock under pressure
Triaxial testing facility: Transition rock under pressure
By Birgit Baustädter Neither hard like stone, nor soft like soil: transition rock is important for almost every construction project, but difficult to study. But this is now possible at the TU Graz. Transition rock is soft rock and hard soil; it is inhomogeneous, anisotropic and brittle. "This material can be found almost everywhere where building activities are undertaken.

Poorer teens at substantially greater risk of obesity
More than one third of UK teenagers are starting adult life with excess weight (either overweight or obese), and rates are even higher among the poorest, finds a new study led by UCL researchers. The research, published today in a briefing paper  by the Centre for Longitudinal Studies (CLS) at the UCL Social Research Institute, shows that one in five (21%) young people were obese at age 17, and a further one in seven (14%) were overweight, based on data collected in 2018-19 .

AI-supported test predicts eye disease three years before symptoms
A pioneering new eye test, developed by scientists at UCL in collaboration with the Western Eye Hospital, London, may predict wet AMD, a leading cause of severe sight loss, three years before symptoms develop. Researchers hope their test could be used to identify the disease early enough so that treatment can effectively prevent any vision loss.

Survey says: Canadians asking for better food systems and food sparked by COVID-19 access
Shopping anxiety, higher food prices and individual income limitations are some of the factors making access to food challenging for Canadians during the COVID-19 pandemic, a new study suggests. Researchers conducted an online inter-provincial survey with residents of B.C. Alberta, Ontario, Quebec and the Atlantic provinces during the first wave of COVID-19.
