Mapping the cellular circuits behind spitting
For over a decade, researchers have known that the roundworm Caenorhabditis elegans can detect and avoid short-wavelength light, despite lacking eyes and the light-absorbing molecules required for sight. As a graduate student in the Horvitz lab, Nikh.....»»
UK court overturns govt go-ahead for Stonehenge road tunnel
A British court on Friday overturned government approval for the construction of a controversial road tunnel close to the Stonehenge stone circle, following opposition from historians, archaeologists and druids......»»
Combining two approaches to advance quantum computing
Quantum computers hold the potential to out-perform all conventional computing systems. Two promising physical implementations for the storage and manipulation of quantum information are the electromagnetic modes of superconducting circuits and the s.....»»
Flexible Computer Processor is the Most Powerful Plastic Chip Yet
Could a flexible processor stuck on your produce track the freshness of your cantaloupe? That's the idea behind the latest processor from UK computer chip designer Arm, which says such a device could be manufactured for pennies by printing circuits d.....»»
How micro-circuits in the brain regulate fear
The brain mechanisms underlying the suppression of fear responses have attracted a lot of attention as they are relevant for therapy of human anxiety disorders. Despite our broad understanding of the different brain regions activated during the exper.....»»
Biomolecular bonsai: Controlling the pruning and strengthening of neuron branches
How neuronal circuits remodel themselves over time, especially during early development, is a major question in neurobiology. Using mice, researchers have uncovered a biomolecular mechanism behind the strengthening of connections from neurons called.....»»
Scientists take first snapshots of ultrafast switching in a quantum electronic device
Electronic circuits that compute and store information contain millions of tiny switches that control the flow of electric current. A deeper understanding of how these tiny switches work could help researchers push the frontiers of modern computing......»»
Scientists develop novel DNA logic circuits
Based on the complementary base pairing rules, a variety of complex secondary structures can be designed and assembled to develop DNA molecular devices with specific functions which play an important role in diverse research fields......»»
Circle is a good example of why SPACs can be useful
Circle is the sort of business that is correct for a SPAC-led debut. It could not go public in a traditional manner in its current state of maturity. In the wake of Coinbase’s direct listing earlier this year, other crypto companies m.....»»
Synthetic biology circuits can respond within seconds
Synthetic biology offers a way to engineer cells to perform novel functions, such as glowing with fluorescent light when they detect a certain chemical. Usually, this is done by altering cells so they express genes that can be triggered by a certain.....»»
Circle wants to help companies access DeFi lending markets with new API
Cryptocurrency company Circle has announced that it plans to launch a new API for companies using Circle accounts to manage crypto assets — and in particular USDC stablecoins. The new API will let companies access decentralized finance (DeFi) proto.....»»
Jeff Bezos is going to space for 11 minutes. Here"s how risky that is
Jeff Bezos can have anything. He could circle the globe in a private jet or sail it forever in a fleet of megayachts. He could afford to buy a the whole NFL; he could buy an archipelago for his family and friends; he could buy over 65,000 Bugatti Chi.....»»
Changing the shape of soft matter using logic circuits made from DNA
The myriad processes occurring in biological cells may seem unbelievably complex at first glance. And yet, in principle, they are merely a logical succession of events, and could even be used to form digital circuits. Researchers have now developed a.....»»
New method developed to improve durability of nano-electronic components, further semiconductor manufacturing
University of South Florida researchers recently developed a novel approach to mitigating electromigration in nanoscale electronic interconnects that are ubiquitous in state-of-the-art integrated circuits. This was achieved by coating copper metal in.....»»
A new direction of topological research is ready for take off
In a joint effort, ct.qmat scientists from Dresden, Rostock, and Würzburg have accomplished non-Hermitian topological states of matter in topolectric circuits. The latter acronym refers to topological and electrical, giving a name to the realization.....»»
Study of bat navigation in extra-large spaces reveals an unknown neuronal code
The brain is often likened to a computer, its hardware consisting of neurons organized in complex circuits; its software a plethora of codes that govern the neurons' behavior. But sometimes, the brain performs exceptionally well even when its hardwar.....»»
For Native Americans, Harvard and other colleges fall short
When Samantha Maltais steps onto Harvard's campus this fall, she'll become the first member of the Aquinnah Wampanoag tribe to attend its prestigious law school. It's a "full-circle moment" for the university and the Martha's Vineyard tribe, she says.....»»
Rare 4000-year comets can cause meteor showers on Earth
Comets that circle the Sun in very elongated orbits spread their debris so thin along their orbit or eject it out of the solar system altogether so that their meteor showers are hard to detect. From a new meteor shower survey published in the journal.....»»
Study reveals food scarcity, desperate diet of Marine killed in Korean War
In the subzero twilight of Nov. 27, 1950, embedded next to the Chosin Reservoir and surrounded by the slopes of treacherous terrain, the 1st Battalion, 7th Regiment of the 1st Marine Division found itself at the center of a closing circle—and an ea.....»»
Better integrated circuits with glide symmetry
Surface plasmon polaritons (SPPs) are highly localized surface waves on the interface between metal and dielectric in the optical frequency band. SPPs do not naturally exist in the microwave and terahertz frequencies, so "spoof" surface plasmon polar.....»»
