Switched on IR-active organic pigments
In photosynthesis and organic photovoltaics, pigment molecules convert light into electrical charge. A team of chemists have now produced an unusual organic pigment, which is "switched on" by an electrical charge to become a potent dye that absorbs l.....»»
A promising target for new RNA therapeutics now accessible
Only recently, a new era in medicine began with the first RNA vaccines. These active substances are modified RNAs that trigger immune responses of the human immune system. Another approach in RNA medicine targets the body's own RNA and its protein mo.....»»
Critical takeover vulnerabilities in 92,000 D-Link devices under active exploitation
D-Link won't be patching vulnerable NAS devices because they're no longer supported. Enlarge (credit: Getty Images) Hackers are actively exploiting a pair of recently discovered vulnerabilities to remotely commandeer net.....»»
High-performance terahertz modulators induced by substrate field in Te-based all-2D heterojunctions
High-performance active terahertz (THz) modulators are of great importance for next generation communication technology. However, they currently suffer from the tradeoff between modulation depth and speed......»»
A simple, inexpensive way to make carbon atoms bind together
The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon—a carbon atom bond.....»»
Tiny cracks in rocks may have concentrated chemicals needed for life
The gentle flow of warm fluids could have given pre-life chemistry a boost. Enlarge / Active geology could have helped purify key chemicals needed for life. (credit: Christof B. Mast) In some ways, the origin of life is.....»»
Pacific rock samples offer glimpse of active Earth 2.5 billion years ago
In Earth science, small details can help explain massive events. Rita Parai, an assistant professor of Earth, environmental and planetary sciences in Arts & Sciences at Washington University in St. Louis, uses precision equipment to measure trace lev.....»»
A new estimate of US soil organic carbon to improve Earth system models
Soil contains about twice as much carbon as the atmosphere and plants combined. It is a major carbon sink, capable of absorbing more carbon dioxide from the atmosphere than it releases. Management of soil carbon is key in efforts to mitigate climate.....»»
Cloud Active Defense: Open-source cloud protection
Cloud Active Defense is an open-source solution that integrates decoys into cloud infrastructure. It creates a dilemma for attackers: risk attacking and being detected immediately, or avoid the traps and reduce their effectiveness. Anyone, including.....»»
Archaeologists illuminate ancient culinary practices using chemical biomarkers
Ceramic pots endure the corrosive effects of thousands of years, and organic remains preserved inside the pores can shed light on the culture, values, diets, and daily life of societies. This research is achieved with the help of biomarkers......»»
Researchers show depth-dependent responses of soil organic carbon under nitrogen deposition
In a study published in Global Change Biology, scientists from the Institute of Earth Environment and the South China Botanical Garden of the Chinese Academy of Sciences have shed light on understanding the effects of nitrogen addition on soil organi.....»»
Researchers develop a thermoelectric material with optimal cost, efficiency and flexibility
A research team has developed an inorganic-organic thermoelectric composite that promises competitive pricing while addressing efficiency and flexibility challenges in thermoelectric technology......»»
Cats with MDR1 mutation at risk of severe reactions to popular medication
More than half a million cats in the United States could be at risk of a severe or even fatal neurological reaction to the active ingredient in some top-selling parasite preventatives for felines......»»
Promising advances in organosilica membranes for separating organic liquid mixtures
In many chemical-related industries, such as pharmaceuticals, oil refineries, and food and beverage factories, separating organic liquid mixtures is an essential step. A staple method to achieve this is distillation, which involves heating a mixture.....»»
SWAT team’s Spot robot shot multiple times during standoff
It's believed to be the first time Boston Dynamics' dog-like robot has taken a bullet during active duty and highlights how it can make police work safer......»»
Sleeping supermassive black holes awakened briefly by shredded stars
A new investigation into an obscure class of galaxies known as Compact Symmetric Objects, or CSOs, has revealed that these objects are not entirely what they seem. CSOs are active galaxies that host supermassive black holes at their cores. Out of the.....»»
Curbside collection improves organic waste composting, reduces methane emissions
Most organic household waste ends up in landfills, where it generates methane, a powerful greenhouse gas. Composting food and garden waste instead of sending it to landfills can significantly reduce methane emissions and help mitigate global warming......»»
Researchers challenge the limits of molecular memory, opening the door to the development of molecular chips
Some molecules respond to external light pulses by changing their structure and holding certain states that can be switched from one to another. These are commonly referred to as photoswitches and usually have two possible states. Recently, however,.....»»
New study reveals influencers of global biogenic volatile organic compound emission trends over the last 20 years
Biogenic volatile organic compounds (BVOCs) emitted by vegetation are important precursors of ozone and secondary organic aerosols in the atmosphere, affecting air quality, clouds, and climate. However, BVOC emissions remain highly uncertain because.....»»
Additional nutrients intensify dead zones in oceans, researchers find
As more and more nutrients from land and air enter the world's oceans, the dead zones without oxygen in the water will increase in size and intensity. That is the warning that Ph.D. student Zoë van Kemenade, an organic geochemist at NIOZ, draws from.....»»
Integration of theory prediction and experimental electrooxidation of glycerol on nanosheets
Glycerol, a major by-product of biomass refining accounting for approximately 10% of the yield, presents a significant challenge due to its global surplus. The presence of multiple active hydroxyl groups in glycerol unveils vast potential for the pro.....»»
