New sensor uses MRI to detect light deep in the brain
Using this approach, researchers can map how light spreads in opaque environments. Using a specialized MRI sensor, MIT researchers have shown that they can detect light deep within tissues such as the brain. Imaging light in deep tissues is extremely difficult because as light travels into tissue, much of it is either absorbed or scattered.

New model explaining difficulty in language comprehension
Built on recent advances in machine learning, the model predicts how well individuals will produce and comprehend sentences. Cognitive scientists have long sought to understand what makes some sentences more difficult to comprehend than others. Any account of language comprehension, researchers believe, would benefit from understanding difficulties in comprehension.

New tool can assist with identifying carbohydrate-binding proteins
Groundbreaking research can help alleviate the challenges affiliated with studying carbohydrates. One of the major obstacles that those conducting research on carbohydrates are constantly working to overcome is the limited array of tools available to decipher the role of sugars. As a workaround, most researchers utilize lectins (sugar-binding proteins) isolated from plants or fungi, but they are large, with weak binding, and they are limited in their specificity and in the scope of sugars that they detect.

New activity trackers for dolphin conservation
Experiments with custom-made biologging devices offer new insight into dolphin swimming and energy requirements Study: Tag-based estimates of bottlenose dolphin swimming behavior and energetics. (DOI: 10.1242/jeb. Just like a smartwatch can tell its wearer how many calories they consume during exercise, data from dolphin wearables can now be used to estimate how much energy dolphins use when they swim.

Why some wet surfaces are less slippery
Why some wet surfaces are less slippery
Many surfaces get slippery when wet. Some surfaces have the opposite behaviour: they get less slippery. UvA researchers have now shed light on why this is the case. Hydrogen bonds between the surface and the water turn out to play an important role. The research, carried out by PhD candidate Liang Peng in collaboration with five physicists and chemists from UvA, ARCNL and the German Max Planck Institute for Polymer Research, was published in Physical Review Letters this week.

Better procurement policies boost construction innovation
Reusing asphalt or making a movable bridge deck out of biocomposite material are just two examples of innovation in the world of civil construction. Municipalities, provinces and other major infrastructure clients are in a position to push for such innovations in their tenders. But new techniques can come with construction risks that companies are not always willing to take.

A process to produce fuel from banana peel
A process to produce fuel from banana peel
This green process could be used to valorize other food remains rich in cellulose or lignin The banana is an excellent source of energy, nutritionists will tell you unanimously. So is the peel, according to Marie-Josée Dumont, but in the fuel sense of the term. The professor from the Department of Chemical Engineering at Laval University and her colleagues at McGill University have just taken a new step towards a fuel based on banana peel by substantially improving the efficiency of an existing chemical process.

The forgotten half of the brain to recover memory
The forgotten half of the brain to recover memory
A research team at the University of Lausanne has succeeded in preserving the memory of Alzheimer's mice by boosting the metabolic functions of glial cells rather than neurons, a striking shift in treatment strategies. The results can be found in the journal "Glia". Alzheimer's disease progressively affects the memory until the loss of autonomy of individuals.

Sharpsnout seabream's mortality during early life stages has a genetic base
Sharpsnout seabream’s mortality during early life stages has a genetic base
The high mortality in the early stages of life is a common phenomenon in fish and other species, but it is little studied due to its complexity. A study by the University of Barcelona and the Centre for Advanced Studies of Blanes (CEAB-CSIC) has analysed whether this mortality in the sharpsnout seabream ( Diplodus puntazzo ), a species of the Mediterranean with an important commercial interest, occurs by chance or whether it is genetically determined.

A team of researchers, led by the UPF, characterize rare, damaged cells (senescent cells) that block the functions of their neighbour healthy cells and identify ways to neutralize them and improve tissue regeneration
Senescent cells, which emerge after tissue injury, create an aged-like inflamed microenvironment that is negative for stem cell function and tissue repair. The finding provides a basis for mitigating the loss of muscle regenerative capacity in elderly people and for improving muscle repair in young healthy people.

COMPASS for Highly Sensitive Rapid Tests
COMPASS for Highly Sensitive Rapid Tests
A newly developed rapid test needs only a few seconds to reliably detect pathogens such as SARS-CoV-2. It is based on specially designed magnetic nanoparticles. The current rapid tests for diagnosing infectious diseases are speedy, but not really fast. For example, antigen self-tests, PCR tests or ELISA tests for coronavirus take 15 minutes to several hours before a reliable result is available.

Gender equality is good for economic growth
Over 500 years, the economy developed better in parts of Europe where women married in their 20s instead of their teens, according to a study by economic historians Alexandra de Pleijt from Wa-geningen University in the Netherlands and Jörg Baten from the University of. Their study has been published in the journal World Development .

A mathematical model shows a global trend towards mutualism between species
A team led by researchers from Universidad Carlos III de Madrid (UC3M) and Universidad Politécnica de Madrid (UPM) has developed a new mathematical model to study changes in ecological interactions between microbe populations. One of the conclusions they have found is that there is a trend towards mutualism, that is, towards a relationship in which species benefit each other.

Acids help against airborne viruses
Acids help against airborne viruses
A new study by various Swiss universities shows that aerosols in indoor air can vary in acidity. This acidity determines how long viruses remain infectious in the air - with profound implications for virus transmission and strategies to contain it. Viruses such as SARS-CoV-2, influenza virus and others travel from person to person essentially by hitchhiking on aerosols.

Photonic chip with record-breaking radio frequency dynamic range
Researchers at the University of Twente have developed a revolutionary programmable integrated microwave photonic filter with a record-breaking dynamic range. This represents a major breakthrough in the integration of functionality and performance in radio frequency photonic signal processors. David Marpaung, one of the authors of the study says: "Our work breaks the conventional and fragmented approach of integration, functionality and performance that currently prevents the adoption of these photonic systems in real applications.

How nerve and vascular cells coordinate their growth
How nerve and vascular cells coordinate their growth
Study by the Universities of Bonn and Heidelberg provides insights into a carefully choreographed dance Nerve cells need a lot of energy and oxygen. They receive both through the blood. This is why nerve tissue is usually crisscrossed by a large number of blood vessels. But what prevents neurons and vascular cells from getting in each other's way as they grow? Researchers at the Universities of Heidelberg and Bonn, together with international partners, have identified a mechanism that takes care of this.
