Potent trivalent inhibitors of thrombin from anticoagulation peptides in insect saliva
Thrombosis, the clogging of blood vessels, is a major cause of heart attacks and embolism. Scientists have now engineered the first inhibitors of thrombin, a protease promoting thrombosis, that is three-fold efficient. In a study published in the jou.....»»
A single peptide helps starfish get rid of a limb when attacked
A signaling molecule that's so potent injected animals may drop more than one limb. Enlarge (credit: Hal Beral) For many creatures, having a limb caught in a predator’s mouth is usually a death sentence. Not starfish,.....»»
Researchers develop novel covalent organic frameworks for precise cancer treatment delivery
A team of researchers at NYU Abu Dhabi (NYUAD), led by Program Head of Chemistry Ali Trabolsi, have developed nanoscale covalent organic frameworks (nCOFs), crystalline organic polymers that have been modified with peptides to treat the most aggressi.....»»
Human "molecular map" contributes to the understanding of disease mechanisms
Scientists at Weill Cornell Medicine in Qatar (WCM-Q) have created an intricate molecular map of the human body and its complex physiological processes based on the analysis of thousands of molecules in blood, urine and saliva samples from 391 volunt.....»»
Pollution of the potent warming gas methane soars and people are mostly to blame
The amount and proportion of the powerful heat-trapping gas methane that humans spew into the atmosphere is rising, helping to turbocharge climate change, a new study finds......»»
Algorithm maps protein degradation patterns to improve infection diagnosis and treatment
Peptides are small fragments of proteins, mainly found in the skin and mucous membranes. Some peptides act as a barrier, protecting the body against infections by fighting off microorganisms like bacteria, viruses, and other pathogens, while others p.....»»
The 15 top methane-emitting nations lack policies to rein them in
While the United States and China have taken important steps to reduce their methane emissions, other significant producers of the potent greenhouse gas rarely have concrete national plans to mitigate it, according to a new University of Maryland ana.....»»
Scientists uncover hidden source of snow melt: Dark brown carbon
Wildfires leave potent climate heaters behind in their wake, particles that enhance the absorption of sunlight and warm the atmosphere. Dropped on snow like a wool poncho, these aerosols darken and decrease the surface reflectance of snowy places......»»
Denmark reports cases of bluetongue disease that can be fatal to sheep but is harmless to humans
Denmark reported Tuesday cases of bluetongue in the country's east, a non-contagious, insect-borne viral disease that is harmless to humans but can be fatal for so-called ruminant animals—mainly sheep but also cows and goats......»»
I didn’t expect the Core i5-14600K to beat the Ryzen 5 9600X
The Ryzen 5 9600X is AMD's latest and great mainstream CPU, but Intel's Core i5-14600K provides potent competition......»»
Study reveals bioactive power of a natural spearmint compound against weeds
A recent study reveals the natural compound (-)-carvone in spearmint as a potent and sustainable alternative to chemical herbicides. This research demonstrates how (-)-carvone targets and degrades microtubules in weeds, inducing cell death and inhibi.....»»
Are Earth"s missing millions of undescribed insect species extinction-prone?
In new research, Griffith ecologists have highlighted the millions of insects that remain undiscovered and unnamed by scientists were likely to be more vulnerable to extinction than named species......»»
Study shows effective regulation and monitoring is key to tackling emissions of a super-greenhouse gas
New research has revealed factories globally are not properly destroying one of the most potent greenhouse gases emitted from the production of fluoropolymers like Teflon, and refrigerants......»»
Trees stripped by invasive caterpillars muster defenses that can harm native insects, research shows
An invasive insect with an insatiable appetite can cause serious problems for a favorite native moth that likes the same food source—even though the two are never in direct competition for a meal, according to new research, published in the journal.....»»
"Masters of shape-shifting": How darkling beetles conquered the world
Large-scale genomic analysis of darkling beetles, a hyper-diverse insect group of more than 30,000 species worldwide, rolls back the curtain on a 150-million-year evolutionary tale of one of Earth's most ecologically important yet inconspicuous creat.....»»
X-ray irradiation technique helps to control cancer-causing poison in corn
Corn, a staple food crop consumed by billions of people and animals worldwide, is frequently contaminated by the fungal toxin aflatoxin B1, a highly potent carcinogen produced by the fungus Aspergillus flavus......»»
Would you trust an ant to amputate your limb? Science is showing they are skilled surgeons
An insect bites off another insect's leg. Is this predatory behavior, aggression, defense, competition or something else? In the case of carpenter ants, it's for the good of the amputee and to the benefit of the colony......»»
Researchers find unexpectedly large methane source in overlooked landscape
When Katey Walter Anthony heard rumors of methane, a potent greenhouse gas, ballooning under the lawns of fellow Fairbanks residents, she nearly didn't believe it......»»
Ancient poppy seeds and willow wood offer clues to the Greenland ice sheet"s last meltdown
As we focused our microscope on the soil sample for the first time, bits of organic material came into view: a tiny poppy seed, the compound eye of an insect, broken willow twigs and spikemoss spores. Dark-colored spheres produced by soil fungi domin.....»»
Invasive insect herbivore alters ecosystem services delivered by cycads
