Trees are crucial organisms in many terrestrial ecosystems. Tree responses to climate variations could influence the global carbon and water cycles considerably and affect the ecosystem services that forests provide. However, ...

Worldwide, an estimated 220 million people are drinking groundwater containing the toxin arsenic (As) at concentrations above the World Health Organization guideline of 10 parts per billion. About 94% of the people at risk ...

Most antivirals in use today target parts of an invading virus itself. Unfortunately, SARS-CoV-2—the virus that causes COVID-19—has proven hard to kill. But viruses rely on cellular mechanisms in human cells to help them ...

A rotating black hole is such an extreme force of nature that it drags surrounding time and space around with it. So it is only natural to ask whether black holes could be used as some sort of energy source. In 1969, mathematical ...

The world was stunned when The Lancet, medicine's most respected scientific journal, retracted a blockbuster article within two weeks of its publication over data credibility.

It's quiet in the laboratory, almost peaceful. But I'm holding live SARS-CoV-2 in my hands and this virus is not to be taken lightly.

In 1935, E. Schrödinger proposed his well-known cat thought experiment suggesting, but not explaining, how a measurement transforms the probable states of an atom into the actual state of a cat (alive or dead). Rather than ...

Despite the pandemic, NASA is on track to launch its Mars rover, Perseverance, this July from Cape Canaveral, Florida. Its central mission will be to search for evidence of previous life on Mars.

Trees marked by Aboriginal cultural practices are a distinctive part of the Australian landscape. A recent discovery on Wiradjuri country in New South Wales shows some of these "culturally modified trees" may be much younger ...

The coronavirus has traveled the globe, infecting one person at a time. Some sick people might not spread the virus much further, but some people infected with the SARS-CoV-2 are what epidemiologists call "superspreaders."

Although bacteria are single-celled and microscopically small, they still need energy to survive, just like us. One of the most efficient ways of acquiring energy for bacteria is through sweet, soluble carbohydrates: sugars.

Crystals only one atom thick are commonly obtained by starting with layered materials, where thousands of individual atomic planes are stacked together by weak van der Waals interactions. Scientists have spent many decades ...
