Breakthrough in plant disease: New enzyme could lead to anti-bacterial pesticides
Plant diseases pose significant challenges to agricultural productivity, presenting formidable hurdles that require urgent attention. Left unchecked, these diseases can spread rapidly, inflicting widespread damage on crops and leading to reduced yiel.....»»
Predicting solar storms before they leave the sun
When giant solar storms hit Earth, they trigger beautiful auroral displays high in Earth's atmosphere. There's a dark side to this solar activity, though. The "space weather" it sets off also threatens our technology. The potential for damage is why.....»»
How Kepler’s 400-year-old sunspot sketches helped solve a modern mystery
A sharp decline in sunspot activity in the 17th century has long puzzled astronomers. Enlarge / A naked-eye sunspot group on May 11, 2024. There are typically 40,000 to 50,000 sunspots observed in ~11-year solar cycles. (credit:.....»»
Senate passed child protection bills that could dramatically regulate social media
The Senate has passed two major child protection bills that could have a dramatic impact on how social media apps operate. If the bills make it through the House to become law, then social media apps would have to make it possible for users to dis.....»»

Green synthesis of copper oxide nanoparticles from mangifera indica: A solution for agricultural disease management
A research team has successfully synthesized green copper oxide nanoparticles (CuO.NPs) from Mangifera indica (M. indica) leaf extract. The CuO.NPs showed potent activity against gram-positive and negative bacteria, as well as fungicidal effects on p.....»»
Imaging below the surface reveals one of Los Angeles"s webs of faults
A major fault is often surrounded by a web of secondary faults created as the forces that cause slip deform nearby rocks. This damage zone can act as a record of fault activity, but what we can learn from it—such as how the fault may behave during.....»»
How to pause Activity Rings in watchOS 11 when you need a break
While Activity Rings are a staple for fitness enthusiasts, there might be times when you need to pause them. Here's how you can do it in watchOS 11.How to pause Activity Rings in watchOS 11The Activity Rings on the Apple Watch are a great way to keep.....»»
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.....»»
Climate is most important factor in where mammals choose to live, study finds
While human activity has had a massive effect on the natural world, a new study from North Carolina State University finds that climate is still the most influential factor in determining where mammals can thrive. The work sheds light on how climate.....»»
Ecommerce activity is causing a spike in pollution by warehouses
Warehouses associated with ecommerce outlets are causing more traffic, which means more local pollution......»»
Research shows the ocean is becoming too loud for oysters
Baby oysters rely on natural acoustic cues to settle in specific environments, but new research from the University of Adelaide reveals that noise from human activity is interfering with this critical process......»»
Nature-inspired novel catalyst paves the way for efficient hydrocarbon decomposition
A research team affiliated with UNIST has developed a novel catalyst that mimics the ability of a natural enzyme to break down harmful hydrocarbons, paving the way for a more environmentally friendly and energy-efficient approach to reducing pollutio.....»»
Researchers advance understanding of a key celiac enzyme
Celiac disease affects around one in a hundred people worldwide, and those that have the autoimmune disorder have no choice but to stick to a gluten-free diet forever—at the moment, doctors have no other way to treat the illness......»»
Study reveals key gene protecting plants from harmful metals in soil
The negative impact of human activity on Earth doesn't just affect our planet's atmosphere—it goes much deeper, into its soils. For instance, excessive application of manure or sewage sludge can increase heavy metal concentrations in agricultural l.....»»
Discovery of a tRNA modification enzyme that also acts on nucleosides
The genetic information on DNA is transcribed into messenger RNA (mRNA) and translated to the amino acid sequence by transfer RNA (tRNA) on the ribosome. Modified nucleosides within RNA are involved in maintaining and regulating the protein synthesis.....»»
Scientists replicate enzyme that captures carbon
Scientists from King's College London have recreated the active site of Acetyl-CoA Synthase, an enzyme involved in capturing carbon from the atmosphere. The research, carried out in collaboration with Imperial College London, advances our understandi.....»»
Gene silencing tool has a need for speed: Research provides deeper insight into RNAi tool design
RNA interference (RNAi) is a process that many organisms, including humans, use to decrease the activity of target RNAs in cells by triggering their degradation or slicing them in half. If the target is a messenger RNA, the intermediary between gene.....»»
Study identifies RNA molecule that regulates cellular aging
A team led by UT Southwestern Medical Center researchers has discovered a new way that cells regulate senescence, an irreversible end to cell division. The findings, published in Cell, could one day lead to new interventions for a variety of conditio.....»»
