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.....»»
Stretchable, flexible, recyclable: 3D printing method creates fantastic plastic
Princeton engineers have developed an easily scalable 3D printing technique to manufacture soft plastics with programmed stretchiness and flexibility that are also recyclable and inexpensive—qualities not typically combined in commercially manufact.....»»
Commission approves Minnesota"s first carbon-capture pipeline: Its future hinges on the Dakotas
Minnesota utility regulators on Dec 12 unanimously approved what would be the state's first carbon dioxide pipeline, stretching 28 rural miles from an ethanol plant near Fergus Falls to the North Dakota border......»»
How much permafrost will melt this century, and where will its carbon go?
Among the many things global warming will be melting this century—sea ice, land glaciers and tourist businesses in seaside towns across the world—is permafrost. Lying underneath 15% of the northern hemisphere, permafrost consists of accumulating.....»»
Bringing the power of tabletop precision lasers for quantum science to the chip scale
For experiments that require ultra-precise measurements and control over atoms—think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates—lasers are the technology of choice, the more spectrally pure (emitting a single col.....»»
New chemical structures show vastly improved carbon capture ability
Oregon State University researchers have synthesized new molecules able to quickly capture significant amounts of carbon dioxide from the air, an important tactic in climate change mitigation......»»
Scientists control quantum states in new energy range
An international team of scientists led by Dr. Lukas Bruder, junior research group leader at the Institute of Physics, University of Freiburg, has succeeded in producing and directly controlling hybrid electron-photon quantum states in helium atoms......»»
How sulfur affects the carbon cycle of subtropical seagrass meadows: New findings from Florida Bay
Seagrass meadows have an important climate protection function due to their long-term carbon storage potential. An international research team led by the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) has now been able to show that seagr.....»»
Brazilian beef and leather companies fall short in tackling deforestation, a study finds
The next United Nations climate conference, COP30, will be held in Belem, the capital of an Amazon region where widespread deforestation mainly driven by cattle farming has turned the surrounding rainforest from a vital carbon sink into a significant.....»»
Two key proteins boost tomato"s phosphorus efficiency and plant health
Phosphorus is a critical nutrient for plant growth, yet it is often locked away in soils and inaccessible to plants. The natural process of arbuscular mycorrhizal symbiosis (AMS), in which plants exchange carbon for essential nutrients with fungi, is.....»»
High velocity clouds comprise less of the Milky Way"s mass than thought, astronomers find
Sometimes in astronomy, a simple question has a difficult answer. One such question is this: what is the mass of our galaxy?.....»»
New technique for spotting Dyson rings unveiled
Dyson spheres and rings have always held a special fascination for me. The concept is simple: build a great big structure either as a sphere or ring to harness the energy from a star. Dyson rings are far more simple and feasible to construct and in a.....»»
Graphene stacking discovery could herald new era for quantum applications
Graphene, a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, is known for its exceptional properties: incredible strength (about 200 times stronger than steel), light weight, flexibility, and excellent conduction of elect.....»»
Sink to source: Arctic is now emitting more carbon than it absorbs
After locking carbon dioxide in its frozen soil for millennia, the Arctic tundra is undergoing a dramatic transformation, driven by frequent wildfires that are turning it into a net source of carbon dioxide emissions, a US agency said Tuesday......»»
The Arctic is on fire: Report details how tundra has become a carbon emitter
Increasingly frequent and severe wildfires have become a yearly concern for many Arctic communities, and a chapter of a new U.S. report involving one Canadian university—Université de Montréal—suggests that they are also having a significant im.....»»
Raspberry Pi 500 makes an 8GB Pi 5 into a compact, inexpensive desktop PC
New Pi 5-powered PC also launches with optional portable 1080p monitor. One of the selling points of the Raspberry Pi 5 (released in October 2023) is that it was fast enough and h.....»»
Not so simple machines: Cracking the code for materials that can learn
It's easy to think that machine learning is a completely digital phenomenon, made possible by computers and algorithms that can mimic brain-like behaviors. But the first machines were analog and now, a small but growing body of research is showing th.....»»
A new global carbon trading market could be held hostage by speculators
Our planet's future hangs in the balance due to the unabated greenhouse gas emissions from burning fossil fuels. Treating these emissions as something that can be owned and exchanged in a market has been touted as a solution since the early 1990s, wh.....»»
Plans to stabilize Earth"s climate rely on emerging carbon removal technology—we need to get moving, say researchers
Global carbon emissions from fossil fuels continue to rise and 2024 is likely to be the world's hottest year on record......»»
This $20 accessory should be in the stocking of every PC gamer
PC gamers are always difficult to shop for, but any PC gamer will appreciate this simple $20 accessory as a gift......»»
Your AI clone could target your family, but there’s a simple defense
The FBI now recommends choosing a secret password to thwart AI voice clones from tricking people. On Tuesday, the US Federal Bureau of Investigation advised Americans to share a s.....»»
