Science, engineering, and discovery — the research and breakthroughs that matter.

Total solar eclipse to spellbind Europe and more — today's student signal.

Millions of Europeans will contemplate the sky in awe on Wednesday as a rare total solar eclipse crosses part of the continent and plunges a swath of Spain into eerie daytime darkness.

Emergency workers attempting to rescue survivors after a recent earthquake in Kyushu, Japan, also had to cope with extreme summer heat.

What does it mean when brown patches show up in a perfectly healthy lawn? The truth is, it could be anything from drought to dog urine, fungal diseases, pests or too much fertilizer. But many homeowners automatically blame grubs.

When social media arrived on the scene, there were high hopes that they would improve—or even "democratize"—communication about climate change by, for instance, lowering access barriers, creating a more direct channel between science and the public, and giving more voices from ci

A University of Kansas physicist played a leading role in a CERN study showing that two rival explanations for how gluons behave inside atomic nuclei can now be experimentally distinguished.

New research introduces a contactless way to see how mirror-image materials respond differently to circularly polarized light, without first building them into a complete electronic device. The researchers developed a novel method based on light-induced charge separation that all

Mitochondria are often called the powerhouses of the cell. But their ancient origins may also make them drivers of inflammation. Researchers at the University of Illinois Chicago have discovered that proteins released from mitochondria can activate the immune system in a similar

A new study has found that sexual role identities among men who have sex with men vary systematically by age and geographic region.

When certain atoms are irradiated with laser light, they can produce a very different kind of laser light: laser pulses with extremely high frequencies in the X-ray range. These laser pulses, which helped achieve record-breaking results at TU Wien in the 1990s, were the subject o

The good news is that the majority of Australian students have again reached proficiency standards in reading and writing literacy—marking almost 20 years of consistent achievement. These results suggest two-thirds of Australian students meet the reading standard, listed as "stro

Toxoplasma gondii, or Toxoplasma, is a parasite that infects hundreds of millions of people around the world. Although cases are often mild, it can cause severe symptoms in people with weakened immune systems and developing fetuses. It can also persist for years by forming long-l

In extreme environments, habitats are built for survival. Submarines, Antarctic bases and post-disaster dwellings are designed to prioritize health and safety. This is especially the case for habitats in space, where room is limited, contact with Earth is remote and hazards are n

Britain is "on course" to chalk up its warmest summer on record for the second year running, the UK's Met Office weather agency said Tuesday as the country braced for its fifth heat wave of the season.

Once used to defend Britain's shores against Napoleonic France, the Ordnance Survey's detailed maps are now essential for tracking and adapting to climate change.

Invented languages tend to be the stuff of fantasy or science fiction worlds. But as a child, you may have made one up yourself.

Sorry, North America. After winning the cosmic lottery with a pair of coast-to-coast total solar eclipses, now it's Europe's turn.

The Roman emperor Julian (332–363 CE) called bread the food that "among us is thought to be the most nourishing."

Emergency workers attempting to rescue survivors after a recent earthquake in Kyushu, Japan, also had to cope with extreme summer heat.

The habitable zone concept is useful for understanding which worlds might, possibly, maybe, be habitable. It highlights exoplanets at the right distances from their stars for liquid water to potentially exist on their surfaces. But that alone can't determine habitability.

What is the past? It may seem a simple question to answer, but it is more complex than we might think at first. As science, politics, technologies and ways of thinking change, so does our understanding of what went before.

Scientists have shown that genomics can help identify which wild populations are most vulnerable to climate change—offering practical guidance for conserving threatened species before declines become irreversible.

Skin appearance plays an important role in the perception of age, health and attractiveness. Of course, skin appearance is affected by actual skin condition, but previous research has also found that it is affected by adjacent surfaces (e.g., eyebrows, eyes and lips).
