Catalyzing ammonia formation at lower temperatures with ruthenium
Nitrogen is an essential nutrient for plant growth. While about 80% of earth is nitrogen, it is mostly contained in the atmosphere as gas, and hence, inaccessible to plants. To boost plant growth, especially in agricultural settings, therefore, chemi.....»»
New model refutes leading theory on how Earth"s continents formed
The formation of Earth's continents billions of years ago set the stage for life to thrive. But scientists disagree over how those land masses formed and if it was through geological processes we still see today......»»
Engineers develop general, high-speed technology to model, understand catalytic reactions
Researchers have been studying the industrial production of ammonia for a century. But they've struggled to find ways to improve the low-yield, low-efficiency process......»»
Giant pangolin rediscovered in Senegal
In March 2023, temperatures in eastern Senegal soared to 40°C, with the cooling rains still months away. Yet, for the dedicated field team from the NGO Panthera—committed to global feline conservation—and the Direction des parcs nationaux du Sé.....»»
First 3D visualization of an aluminum nanocomposite for the auto industry
Manufacturing cars with strong, lightweight aluminum alloys rather than steel could improve fuel efficiency and extend electric vehicle range, but the material's instability at high temperatures has held the alloys back from widespread adoption......»»
Heat claims 175,000 lives a year in Europe: WHO
Heat kills over 175,000 people a year in Europe, where temperatures are rising quicker than the rest of the globe, the World Health Organization's (WHO) European branch said Thursday......»»
Ancient Antarctic microorganisms are aggressive predators
In Antarctica there is a small lake, called Deep Lake, that is so salty it remains ice-free all year round despite temperatures as low as -20°C in winter. Archaea, a unique type of single-celled microorganism, thrive in this bitterly cold environmen.....»»

Extreme heat kills over 175,000 people a year in Europe, where temperatures are rising quicker than the rest of the globe, the World Health Organization's (WHO) European branch said Thursday......»»
Wildfires encroach on homes near Denver as heat hinders fight
A wildfire on the edge of metro Denver crept within a quarter-mile of evacuated homes, but authorities said Thursday morning they were hopeful to save hundreds of threatened residences as they grapple with sweltering temperatures and firefighters suf.....»»
New perspectives for using corals in climate research
Ancient ocean temperatures are most commonly reconstructed by analyzing the ratio of different oxygen atoms in the calcium carbonate remains of fossils. However, this presents many challenges, including a combination of biological processes known as.....»»
Extreme heat in India: A crisis on the rise
As global temperatures continue to rise, India is grappling with increasingly severe heat waves. As early as April, many Indian cities, including New Delhi, the capital, have experienced record temperatures above 115 degrees Fahrenheit......»»
Tipping risks from overshooting 1.5°C can be minimized if warming is swiftly reversed, says research
Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5°C of global warming after a period of overshoot. A new study indicates that these risks can be minimized if warming is.....»»
Paris Olympics athletes and fans melt in "brutal" heat
After heavy rain drenched last week's opening ceremony, the Paris Olympics on Tuesday wrestled with entirely different conditions as temperatures soared to 35 degrees Celsius......»»
Ammonia-free gallium nitride semiconductor production found to improve crystal quality, reduce environmental impact
Gallium nitride (GaN) semiconductors can now be grown without ammonia, a toxic chemical that needs a sophisticated detoxifying system before it can be released into the atmosphere. The new technique is not only more environmentally friendly but also.....»»
The sun"s corona is weirdly hot, and Parker Solar Probe rules out one explanation
By diving into the sun's corona, NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause of the corona's searing temperatures, according to University of Michigan research published in The Astrophysical Journal L.....»»
Stem cell harmony: How solanaceae plants maintain homeostasis through receptor compensation
A pivotal study sheds light on the evolutionary conservation of stem cell homeostasis in Solanaceae, revealing how receptor compensation mechanisms ensure the continuous and orderly formation of plant organs. This research uncovers the genetic interp.....»»
Agricultural soils are efficient ice nucleating particles in the southern great plains
INPs are a rare subset of atmospheric aerosol that can initiate ice formation in clouds. There is a significant gap between scientists' ability to measure INPs and to predict their concentrations and variability in large-scale weather and climate mod.....»»
Genomewide prediction: A promising approach for improving russet formation in apple breeding programs
A research team has demonstrated that genomewide prediction is a promising approach for targeting russet formation in apple breeding programs. This method effectively predicts the russet trait, which is a complex quantitative trait controlled by many.....»»
Astronomers explain rapid formation of organic macromolecules in protoplanetary disks around young stars
An international team of researchers led by the University of Bern has used observation-based computer modeling to find an explanation for how macromolecules can form in a short time in disks of gas and dust around young stars. These findings could b.....»»
NASA data shows July 22 was Earth"s hottest day on record
July 22, 2024, was the hottest day on record, according to a NASA analysis of global daily temperature data. July 21 and 23 of this year also exceeded the previous daily record, set in July 2023. These record-breaking temperatures are part of a long-.....»»
Ensuring quality in tropical vegetables: Addressing chilling injury through antioxidant systems
A research team has found that optimal storage temperatures are crucial for preserving vegetables' quality, with tropical plants particularly susceptible to low temperatures, leading to a "chilling injury" (CI) condition......»»
