A fresh look into grasslands as carbon sinks

Grasslands have the capability to store carbon, functioning as an important tool in a battle against climate change. While scientific interest in grassland soil for carbon sequestration is not new, researchers from the Chinese Academy of Sciences and Colorado State University have provided a fresh analysis of the existing research on soil carbon sequestration in grasslands. According to the...

Researchers fabricate cobalt copper catalysts for methane on metal-organic framework

The world is highly dependent on fossil fuels to power its industry and transportation. These fossil fuels lead to excessive carbon dioxide emission, which contributes to global warming and ocean acidification. One way to reduce this excessive carbon dioxide emission that is harmful to the environment is through the electroreduction of carbon dioxide into value-added fuels or chemicals using...

Cell chatter tells story of arterial thickening

Arteries can become thicker due to high blood pressure. However, the cause of this thickening is unclear. TU/e researchers along with colleagues from Trinity College Dublin in Ireland have developed a new computer model to study the arterial thickening in detail. The model shows that both mechanical changes in the artery due to higher blood pressure and cell communication involving so-called...

A step towards quantum gravity

In Einstein's theory of general relativity, gravity arises when a massive object distorts the fabric of spacetime the way a ball sinks into a piece of stretched cloth. Solving Einstein's equations by using quantities that apply across all space and time coordinates could enable physicists to eventually find their "white whale": a quantum theory of gravity.

First results from the paleomagnetic study of Cumbre Vieja

Josep M. Parés, coordinator of the Geochronology and Geology Program at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), has led the first study of the magnetic properties of the lava and ash produced during the 2021 eruption of the Cumbre Vieja volcano (island of La Palma, Canary Islands, Spain), which has been published in the journal Geosciences.

Elephant tweets highlight divide on conservation issues

An analysis of social media posts has highlighted how attention on Twitter does not align with the most pressing threats to wild elephants, which may have negative consequences for elephant conservation and lead to resentment from local communities that live with elephants.

Will strong and fast-switching artificial muscle be feasible?

In the American action movie "Pacific Rim," giant robots called "Jaegers" fight against unknown monsters to save mankind. These robots are equipped with artificial muscles that mimic real living bodies and defeat monsters with power and speed. Research is being conducted on equipping real robots with artificial muscles like the ones shows in the movie. However, the powerful strength and high speed...

No music training? No problem: Even novices intuit complex music theory

Your co-worker’s annoying humming may be more virtuosic than you think. People without musical training naturally improvise melodies that have hallmarks of tunes composed by professionals, a new study shows. It seems that most individuals follow the arcane rules of music composition, even those who are unaware those rules exist. “It’s cool,” says Samuel Mehr, an expert on...

The future of NASA's laser communications

NASA uses lasers to send information to and from Earth, employing invisible beams to traverse the skies, sending terabytes of data—pictures and videos—to increase our knowledge of the universe. This capability is known as laser, or optical, communications, even though these eye-safe, infrared beams can't be seen by human eyes.

The answer to the ‘egg prick’ question | Brief letters

Egg prickers | Anger management | Dario Fo play | Missing Keir StarmerStephen Walkley (Letters, 11 August) asks what an “egg prick” is, after I mentioned it in a letter. An unkind friend suggested, when my letter appeared, that it’s someone who writes letters to the Guardian about eggs. In fact, it’s a gadget that makes a tiny hole in an eggshell, thereby preventing the shell from breaking...

NASA data, acoustic soundscapes assess health of Amazon rainforest

From space, parts of the Amazon rainforest that have previously been logged or burned may look fully recovered with a healthy, lush, and green canopy. They may seem to be places buzzing with activity and full of sounds. But inside the rainforest the animal life may tell a different story of damage to their environment through a quieter soundscape.
