Virtual tutoring: What started as a pandemic phenomenon has evolved from a temporary fix to an educational fixture‎

When Amanda Neitzel first evaluated a live virtual reading-tutoring program called AirReading two years ago, she found what most educators would have predicted: modest results. One semester of live video tutoring nudged struggling early readers forward by roughly a month's worth of learning. But when she ran the study across a full school year, the difference was extraordinary. Literacy gains more than doubled.

Could exoplanets locked in eternal day and endless night support life?‎

Ever so slightly bigger than Earth, the exoplanet LHS 3844b orbits its parent star, LHS 3844, a red dwarf 48.5 light-years from our solar system. Its rotational speed mirrors its orbital speed. The result? One side of LHS 3844b is perpetually bathed in scorching sunlight, locked into a never-ending, blistering hot day, while the other is forever shrouded in darkness so cold that particles are incapable of movement, a state known as absolute zero (zero Kelvin).

What happened to Australia's snow season? A climate expert explains‎

There's nothing like gliding down a snow-covered slope. That is, if you ask the thousands of people who make an annual pilgrimage to our alpine resorts during the Australian winter. But this year, the start to the snow season has been far from spectacular.

Hidden health risks found in New York City's free-roaming cats‎

Cats may be cute and adorable, but stray and feral cats can sometimes pose a risk to human health. Veterinary researchers have discovered that more than 50% of free-roaming cats in New York City carry parasites that could potentially be transmitted to humans.

10 fathers took extended leave to care for their babies—how their family life changed‎

The UK government launched a major review of parental leave in July 2025, with recommendations expected in early 2027. One question sits at the heart of the review: What difference does parental leave make to family life?

Largest viral-protein library gives researchers new way to probe emerging pathogens‎

To prevent viruses from sickening or killing us—whether it's an individual case of hepatitis B or a COVID pandemic—it's crucial to understand how the proteins they make initiate changes in our bodies that allow them to flourish. A new tool has broadened the scale at which researchers can study these proteins, promising to speed basic discoveries in virology, inform the development of new vaccines and treatments, and help humanity protect against emerging pathogens.

Why bees are struggling to survive this summer‎

You may be spotting dead bumblebees lying on pavements near you during the summer months. There are several reasons for this, some related to the weather and some very much due to humans.

If so many people live with toxoplasmosis, how dangerous is this brain parasite really? Should I be worried?‎

About 1 in 3 people worldwide have been infected with a microscopic parasite called Toxoplasma gondii—or simply "toxo"—which can cause toxoplasmosis. After the initial infection, toxo settles into our muscles and brains, where it can remain for life.

Tiny mountain lakes pose big, overlooked flood risks, new study warns‎

A new international study involving scientists from the University of Aberdeen has revealed a critical blind spot in global climate risk assessments—the growing danger posed by small alpine lakes formed by glacier retreat and permafrost thaw. Published in Nature Sustainability, the research highlights how these lakes, which are often too small to appear in conventional hazard databases, can still unleash sudden and destructive floods with little warning.

New ligand engineering strategy creates more active nanocluster catalysts‎

A joint research group from Tohoku University, Tokyo University of Science, Tokyo Metropolitan University and the Japan Fine Ceramics Center has developed a thermal catalyst that exhibits high carbon monoxide (CO) oxidation activity under low-temperature conditions.
