Study of long-term student engagement challenges 'one great teacher' narrative of education

A positive relationship with a teacher at an early age may help children to feel more engaged with school, but not necessarily in the long term, new research shows. A new study of more than 3,600 young people in Australia shows that their 'school engagement' -- their interest in school and willingness to learn -- fluctuates between ages eight and 15, especially during the transition between...

Researchers prove fundamental limits of electromagnetic energy absorption

Electrical engineers have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers optimize devices designed to block certain frequencies of radiation while allowing others to pass through, for applications such as stealth or wireless communications.

Infections from these bacteria are on the rise: New blood test cuts diagnosis time from months to hours

Researchers have designed a platform to perform blood-based diagnoses of nontuberculosis mycobacteria, simplifying and shortening a long-complicated procedure from 6 months to 2 hours. Rapid, accurate diagnosis has never been more important as cases of NTM infections have continued to increase annually, spreading from subtropical regions to more temperate zones in part due to global climate...

FRYL gene variants linked to a new neurological disorder

A recent study links the FRYL gene to a new neurodevelopmental disorder in humans. They used fruit flies to establish that the loss of a functional copy of the FRY-like transcription coactivator (FRYL) gene is the underlying cause of this new disorder in fourteen individuals.

Vac to the future

Scientists recently published the results of a competition that put researchers to the test. For the competition, part of the NIH-funded Computational Models of Immunity network, teams of researchers from different institutions offered up their best predictions regarding B. pertussis (whooping cough) vaccination.

How fear unfolds inside our brains

The stress-induced mechanisms that cause our brain to produce feelings of fear in the absence of threats -- such as in PTSD -- have been mostly a mystery. Now, neurobiologists have identified the changes in brain biochemistry and mapped the neural circuitry that cause generalized fear experiences.

A new world of 2D material is opening up

Materials that are incredibly thin, only a few atoms thick, exhibit unique properties that make them appealing for energy storage, catalysis and water purification. Researchers have now developed a method that enables the synthesis of hundreds of new 2D materials.

How home food availability affects young children's nutrient intake

Early childhood is an important time for learning about nutrition and establishing healthy eating behaviors. Young children rely on parents to provide food options, and the availability of food in the home affects their dietary choices. A new study looks at changes in home food availability and nutrient intake for children from 2 to 4 years old.

Information overload is a personal and societal danger

We are all aware of the dangers of pollution to our air, water, and earth. In a recently published letter, scientists are advocating for the recognition and mitigation of another type of environmental pollution that poses equivalent personal and societal dangers: information overload.

Surprising insights about debris flows on Mars

The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by liquid water, can also be formed by the action of evaporating CO2 ice, according to a new study.

Gut bacteria important for overcoming milk allergy

Researchers have discovered a link between gut bacteria and the success of milk-allergy oral immunotherapy. The study found that Bifidobacterium -- a genus of beneficial bacteria in the gut -- was associated with a higher chance of successful treatment. The finding may help in the development of more effective oral immunotherapies, perhaps by combining them with probiotic supplements.

It's hearty, it's meaty, it's mold

Scientists are exploring how tuning the genomes of mushrooms and molds can transform these food sources into gourmet, nutrient-packed meals made with minimal processing and a light environmental footprint.

Perovskite solar cells: Vacuum process may offer a short track to commercialization

Which process is best suited for mass production of perovskite solar cells? While solvent-based manufacturing processes are used in laboratories around the world, vacuum vapor-phase deposition processes are still the standard for the production of thin films for photovoltaics or organic light-emitting diodes. A new study that reveals major differences in the scientific discussion of these...
