NASA telescopes start the year with a double bang
A colorful, festive image shows different types of light containing the remains of not one, but at least two exploded stars. This supernova remnant is known as 30 Doradus B (30 Dor B for short) and is part of a larger region of space where stars have.....»»
Piezoelectric-enhanced p-n junctions in photoelectrochemical systems
Photoelectrochemical (PEC) water splitting is a potentially feasible strategy for converting solar energy to green hydrogen. However, current PEC systems suffer from relatively low charge separation efficiency and sluggish water oxidation reaction, w.....»»
Reusing plastic waste to kickstart radical chain reactions, improving process safety and efficiency
Single-use plastics are a major environmental concern, but now, rather than being disposed of as garbage, used plastic bags from the grocery store could be utilized to carry out a reaction that can detoxify hazardous chemicals......»»
Study finds that ecological evidence used by government policy-makers is unstable over time
A large study, led by academics from Royal Holloway, University of London, found research used by policy-makers regarding conservation and environmental management is unstable over time and can quickly become out of date: presenting a serious potenti.....»»
Webb spots a second lensed supernova in a distant galaxy
In November 2023, the James Webb Space Telescope observed a massive cluster of galaxies named MACS J0138.0-2155. Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 appears warped by th.....»»
Electrocatalytic CO₂ conversion advancing toward large-scale deployment
Global CO2 emissions continue to grow, reaching 36.1 Gt in 2022, stimulating the implementation of carbon taxes and impacting energy use. The electrocatalytic CO2 reduction reaction (CO2RR) to produce high value-added chemicals and liquid fuels contr.....»»
Uncontrolled chemical reactions fuel crises at LA County"s two largest landfills
Hundreds of feet underground, in a long-dormant portion of Chiquita Canyon landfill, tons of garbage have been smoldering for months due to an enigmatic chemical reaction......»»
Opinion: COP28 agreement on adapting to climate change kicks the real challenge down the road
COP28 concluded late on Wednesday morning to a mixed reaction. The Dubai agreement extracted a promise from nearly 200 countries to transition away from fossil fuels, but it leaves many questions unanswered when it comes to keeping global average tem.....»»
Computational model captures the elusive transition states of chemical reactions
During a chemical reaction, molecules gain energy until they reach what's known as the transition state—a point of no return from which the reaction must proceed. This state is so fleeting that it's nearly impossible to observe it experimentally......»»
Three novel inorganic clusters accelerate chemical reactions to create carbon–carbon bonds
Perfume, rubbing alcohol, a cholesterol medication and even biological processes all depend on a chemical process called the aldol reaction. The reaction primarily combines compounds to form carbon–carbon bonds, which are incredibly strong and prov.....»»
Research progress in pump-probe experiments at high-intensity laser facilities
The reaction kinetics of energetic materials is a key factor in determining the detonation characteristics and safety. The complexity of the reaction process and the lack of experimental means remain a notable challenge in experimental research and f.....»»
James Webb provides a second view of an exploded star
A beautiful supernova remnant, Cassiopeia A, was recently imaged by the James Webb telescope. See how the observation compares to a previous MIRI image......»»
As school students strike for climate once more, here"s how the movement and its tactics have changed
On Friday, students will once again down textbooks and laptops and go on strike for climate action. Many will give their schools a Climate Doctor's Certificate signed by three leading climate academics......»»
Unexpected discovery at the air-water interface for CO₂ reaction impacting geophysical and biological cycles
Ocean acidification, mammal respiration, and aerosol formation all depend on chemistry that occurs at air-water interfaces. In new research, scientists from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have discover.....»»
Astronomers inspect supernova remnants with MeerKAT
Using the MeerKAT radio telescope, astronomers from the National Radio Astronomy Observatory (NRAO) in Charlottesville, Virginia, and elsewhere have investigated a batch of 36 high latitude supernova remnants. Results of the observations campaign, pu.....»»
Study examines the perceptions of pre-service teachers on peer reaction video feedback
Teacher training courses are integral to teacher education programs. However, they often offer limited opportunities for novice teachers to practice teaching and receive feedback on their performance. In this regard, peer evaluation of a teacher's re.....»»
Laser-induced hydrothermal growth for electrocatalytic applications
In the new study published in the journal International Journal of Extreme Manufacturing on 1 November 2023, researchers from the UK and China reported a novel technique based on a laser-induced hydrothermal reaction (LIHR) mechanism for the growth o.....»»
Cross-cultural mentoring to enhance education for Samoan infants and toddlers in Aotearoa
New research led by AUT academics shows how to enhance early childhood education for Samoan pepe meamea (infants and toddlers)—the majority of whom are taught in English-medium centers......»»
Tesla ready to launch its long-delayed Cybertruck
The EV maker is now displaying Cybertrucks in showrooms before the Nov. 30 event. One salesman in California said reaction to the stainless-steel behemoth has been ‘love it or hate it.'.....»»
macOS Sonoma: How to control reaction effects with hand gestures
