Many more bacteria produce greenhouse gases than previously thought, study finds
Caltech researchers have discovered a new class of enzymes that enable a myriad of bacteria to "breathe" nitrate when in low-oxygen conditions. While this is an evolutionary advantage for bacterial survival, the process produces the greenhouse gas ni.....»»
Three new extinct walnut species discovered in high Arctic mummified forest
In a new study, scientists describe three new, but long-extinct, walnut species on an island above the Arctic Circle. The fossils were discovered further north than any known walnut species, living or extinct, and represent some of the oldest-known r.....»»
New study investigates the reconstruction of the intertropical convergence zone
The study focuses on the so-called Intertropical Convergence Zone (ITCZ), a low-pressure trough near the equator whose position and intensity changes seasonally with the position of the sun. Trade winds from the northern and southern hemispheres meet.....»»
Teaching biology—no more stressing out over structural formulas
Structural formulas are a source of dread for many students, but they're an essential tool in biology lessons. A joint study has shown that the stress levels of students working with chemical formulas are significantly reduced if they are given simpl.....»»
Study projects loss of brown macroalgae and seagrasses with global environmental change
Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role of seaweeds and seagrasses in coastal ecosystems, and.....»»
What can social media tell us about public views on climate change?
IIASA researchers contributed to a new study, analyzing the main narratives in public discussions of climate change on social media. The research is published in the journal Current Research in Environmental Sustainability......»»
Pacific cod can"t rely on coastal safe havens for protection during marine heat waves, study finds
During recent periods of unusually warm water in the Gulf of Alaska, young Pacific cod in near shore safe havens where they typically spend their adolescence did not experience the protective effects those areas typically provide, a new Oregon State.....»»
China calls on scientists of all nations to study lunar samples, but notes obstacle with the US

Fifty-three experts weigh in on the global methane budget
Accurate estimates of atmospheric greenhouse gas levels are needed to understand and address the drivers of climate change. Of particular interest is atmospheric methane, which has increased in concentration by 160% since preindustrial times and acco.....»»
Only 4% of teen football academy prospects make top tier, study finds
Just 4% of talented teen academy prospects make it to the top tier of professional football, a new study has shown. A sample of nearly 200 players, aged between 13–18, also revealed only 6% of the budding ballers even go on to play in lower leagues.....»»
Study determines stellar mass and origin of a protostellar system
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have conducted molecular line observations of a protostellar system known as VLA 1623. Results of the observational campaign, published June 18 on the pre-print server arXiv,.....»»
Newly-discovered bacterial regulatory mechanism has implications for antibacterial control measures
Research spearheaded by four biologists within the College of Arts and Sciences at Indiana University Bloomington has uncovered a new regulatory mechanism shared by many bacteria, which may have profound implications for anti-bacterial control measur.....»»
Scientists uncover previously unknown properties of gallium
Nearly 150 years after gallium was discovered and added to the periodic table, University of Auckland scientists have uncovered previously-unknown aspects of the metal's structure and behavior......»»
New strategy to obtain carbon nanotube fibers with higher dynamic strength
In a study published in Science on June 21, Prof. Jian Muqiang from Peking University and the Beijing Graphene Institute and others developed a strategy to fabricate carbon nanotube fibers with the dynamic strength up to 14 GPa......»»
Changing water conservation attitudes positively impacts water availability, study finds
The increased demand for clean water and its limited supply has made water management one of the most pressing challenges facing society today. Changing attitudes about water conservation could significantly impact water consumption and help address.....»»
Wind tunnel study shows hypersonic jet engine flow can be controlled optically
What if the future of space travel were to look less like Space-X's rocket-based Starship and more like NASA's "Hyper-X," the hypersonic jet plane that, 20 years ago this year, flew faster than any other aircraft before or since?.....»»
Do vertebrate populations really decline so much? Calculations indicating severe declines might be wrong, says study
A widely-used Living Planet Index (LPI) characterizes the average change in population sizes of vertebrates and is considered one of the main indicators of the state of the planet......»»
Antarctic ice shelves hold twice as much meltwater as previously thought
Slush—water-soaked snow—makes up more than half of all meltwater on the Antarctic ice shelves during the height of summer, yet is poorly accounted for in regional climate models......»»
Phytochemical diversity and herbivory are higher in tropical forests, says study
It is widely accepted that biological interactions are stronger or more important in generating and maintaining biodiversity in the tropics than in temperate regions. However, this hypothesis has not been fully tested in ecology and evolutionary biol.....»»
Early childhood problems linked to persistent school absenteeism
Children who are not considered "school-ready" by their teachers are more than twice as likely to become persistently absent at some point in their education, according to a new study led by the University of Leeds......»»
Looking for atmospheres in the ultimate quest for extraterrestrial life
To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba has used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his.....»»
