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.....»»
A blue miracle in the Eifel: How sapphires formed in volcanoes
Researchers at Heidelberg University are studying the formation of this characteristically blue-colored crystal in volcanic melts.....»»
Researchers find sucrose breakdown is key to melon seed germination in cold conditions
A research team has found that cold-tolerant melon seeds (THY) maintained higher neutral invertase activity at low temperatures, enabling sustained sucrose decomposition into glucose, which supports seed germination. This contrasts with cold-sensitiv.....»»
Wind, temperatures pick up as fire scorches northern California
Crews continued to fight a massive fire in northern California on Sunday, as authorities in the western US state warned of increasing winds and rising daytime temperatures......»»
Saturday Citations: E-bike accident spike; epigenetics in memory formation; Komodo dragons now scarier
This week, we reported on new epigenetic findings in memory formation as well as a dramatic spike in micromobility-related head injuries, so there's a whole lot of head-related science on the front burner these days. There were new findings regarding.....»»
Last Monday Was the Hottest Day on Record
The record for daily global temperature, recorded by taking averages of land and sea temperatures around the world, was shattered twice last week......»»
Ice 0: Researchers discover a new mechanism for ice formation
Ice is far more complicated than most of us realize, with over 20 different varieties known to science, forming under various combinations of pressure and temperature. The kind we use to chill our drinks is known as ice I, and it's one of the few for.....»»
Stud offers insights for the future design of highly efficient multi-element electrocatalysts
Professor Zhe Weng and Chunpeng Yang from Tianjin University published a paper titled "Unveiling multi-element synergy in polymetallic oxides for efficient nitrate reduction to ammonia" in the journal Science China Materials......»»
New research underscores the close relationship between Saharan dust and hurricane rainfall
Giant plumes of Sahara Desert dust that gust across the Atlantic can suppress hurricane formation over the ocean and affect weather in North America. But thick dust plumes can also lead to heavier rainfall—and potentially more destruction—from la.....»»
Stress granules found to play an unsuspected role in blood vessel formation
The behavior of the cells that make up our blood vessels is crucial to our well-being. Conditions such as inflammation, oxygen deprivation and viral infection can stress these cells and disrupt the formation of new, often pathological, blood vessels......»»
Next generation biosensor reveals gibberellin"s critical role in legume nitrogen-fixation
Researchers at the University of Cambridge have demonstrated that the plant hormone gibberellin (GA) is essential for the formation and maturation of nitrogen-fixing root nodules in legumes and can also increase nodule size. They identified the speci.....»»
380-million-year-old rocks provide insights into past climate and geothermal energy
Rocks undergo changes over millions of years. Yet it is possible to extract information from them about the climate at the time of their formation......»»
Heat-sensitive trees moving uphill due to rising temperatures, study finds
Trees in the Brazilian Atlantic Forest are migrating in search of more favorable temperatures, with species in mountain forests moving uphill to escape rising heat caused by climate change, a new study reveals......»»
Spontaneous supercrystal discovered in switching metal-insulator
A supercrystal formation previously unobserved in a metal-insulating material was discovered by a Cornell-led research team, potentially unlocking new ways to engineer materials and devices with tunable electronic properties......»»
How mantle hydration changes over the lifetime of a subduction zone
Because of interactions with Earth's hot mantle, water-logged oceanic plates release water as they slide beneath less dense overriding plates in subduction zones. This water rises and hydrates the mantle above it, contributing to the formation of vol.....»»
Working to strengthen Pacific Northwest defenses against wildfires and wildfire smoke
In the summer of 2020, wildfire smoke blanketed the city of Portland, Oregon, leading to a prolonged period of poor air quality and health concerns for residents. Subsequently, in 2021 the city experienced a heat wave with temperatures reaching as hi.....»»
Don"t underestimate the increasingly warm summer temperatures, says Swiss expert
What's happened to the summer? I've been asked this question a lot over the past few weeks. Just like May, June was changeable, wet and lacking in sunshine. But it wasn't too cold. According to MeteoSwiss, the average daily temperature in June was st.....»»
One half of this wild exoplanet reaches temperatures of 1,450 degrees Fahrenheit
On the planet WASP-39 b, one side is in perpetual morning and the other is in perpetual evening......»»
"It"s unbearable": heat waves scorch southern and eastern Europe
Unrelenting heat is blanketing swathes of southern and eastern Europe, with dozens of cities on red alert as scorching temperatures fuel wildfires, strain power grids, and make daily life unbearable......»»
Baby bull sharks are thriving in Texas and Alabama bays as the Gulf of Mexico warms
In late spring, estuaries along the U.S. Gulf Coast come alive with newborn fish and other sea life. While some species have struggled to adjust to the region's rising water temperatures in recent years, one is thriving: juvenile bull sharks......»»
Unlocking the genetic code of Amur grape: Insights into plant cold tolerance and evolution
