Money talks when trying to influence climate change legislation

Climate lobbying is big business. A new analysis shows that between 2000 and 2016, lobbyists spent more than two billion dollars on influencing relevant legislation in the US Congress. Unsurprisingly, sectors that could be negatively affected by bills limiting carbon emissions, such as the electrical utilities sector, fossil fuel companies and transportation corporations had the deepest pockets.

Quantum dot white LEDs achieve record efficiency

Researchers have demonstrated nanomaterial-based white-light-emitting diodes (LEDs) that exhibit a record luminous efficiency of 105 lumens per watt.

Brain function partly replicated by nanomaterials

Researchers have created extremely dense, random SWNT/POM network molecular neuromorphic devices, generating spontaneous spikes similar to nerve impulses of neurons. They conducted simulation calculations of the random molecular network model complexed with POM molecules, which are able to store electric charges, replicating spikes generated from the random molecular network. They also demonstrated that this molecular model would very likely become a component of reservoir computing devices. Reservoir computing is anticipated as next-generation artificial intelligence.

Simpler interferometer can fine tune even the quickest pulses of light

A super compact interferometer will give scientists an unprecedented ability to fine tune even the quickest pulses of light for a host of applications, and could render traditional instruments for measuring light beams obsolete.

Carbon nanotubes used to develop clothing that can double as batteries

Engineers are creating clothing that can charge your cell phone. What makes this possible are the unique properties of carbon nanotubes: a large surface area that is strong, conductive and heat-resistant.

‘Star in a jar’: World record for stellarators set

When Germany’s Wendelstein 7-X fusion facility set a world record for stellarators recently, a finely tuned instrument proved the achievement. The record strongly suggests that the design of the stellarator can be developed to capture on Earth the fusion that drives the sun and stars.

Biosensor chip detects single nucleotide polymorphism wirelessly, with higher sensitivity

Scientists have developed a chip that can detect a type of genetic mutation known as a single nucleotide polymorphism (SNP) and send the results in real time to an electronic device. The chip is at least 1,000 times more sensitive at detecting an SNP than current technology. The advance could lead to cheaper, faster and portable biosensors for early detection of genetic markers for diseases such as cancer.

Swimming bacteria work together to go with the flow

Swimming bacteria can reduce the viscosity of ordinary liquids like water and make them flow more easily, sometimes down to the point where the viscosity becomes zero: the flow is then frictionless.
