Cooling speeds up electrons in bacterial nanowires
The ground beneath our feet and under the ocean floor is an electrically-charged grid, the product of bacteria "exhaling" excess electrons through tiny nanowires in an environment lacking oxygen......»»
Research reveals a rare enzyme role change with bacterial defense system assembly
Scientists have revealed a never-before-seen phenomenon in a protein: Alone, the enzyme processes DNA and RNA but, when bound to another protein as part of a defense system, interacts with a completely different type of compound to help bacteria comm.....»»
A new microfabrication strategy for multifunctional 3D artificial sharkskin
Sharks in nature swim at high speeds in a deep ocean due to their high drag reduction ability. Water flows around the sharkskin become disrupted by staggered and overlapping microscale structures named denticles. In addition to this surface roughness.....»»
Permselectivity reveals a cool side of nanopores
Researchers from Osaka University investigated the thermal energy changes across nanopores that allow the selective flow of ions. Switching off the flow of ions in one direction led to a cooling effect. The findings have applications in nanofluidic d.....»»
T-Mobile hits 4.3 Gbps download speeds with mmWave 5G SA test
T-Mobile has been making impressive progress on carrier aggregation 5G SA over the last couple of years. Without mmWave, it has hit up to 3.3 Gbps download speeds. Now the Uncarrier says using mmWave, its 5G SA can deliver a whopping 4.3 Gbps for dow.....»»
A novel microscope operates on the quantum state of single electrons
Physicists at the University of Regensburg have found a way to manipulate the quantum state of individual electrons using a microscope with atomic resolution. The results of the study have now been published in the journal Nature......»»
Nanomaterial with "light switch" kills Gram-negative or Gram-positive bacteria
Health care-associated infections are a common problem in suppurating wound care, as is the rise in multi-drug resistant bacteria. In order to effectively and selectively combat bacterial infections, a team of researchers has developed a bactericidal.....»»
New study finds that male pathology in songbirds drives avian epidemic dynamics
New findings by biological sciences researchers at the University of Arkansas indicate that males play an outsized role in both the infection rate and spread of the avian bacterial pathogen Mycoplasma gallisepticum, a common cause of conjunctivitis i.....»»
Physicist explains X-rays that shouldn"t exist in "cold" plasma
For about 20 years, Caltech Professor of Applied Physics Paul Bellan and his group have been creating magnetically accelerated jets of plasma, an electrically conducting gas composed of ions and electrons, in a vacuum chamber big enough to hold a per.....»»
Collisions change how fast ions surf on plasma waves in fusion experiments and beyond
Just like there are waves in the ocean, waves can also occur in an electrically charged gas called a plasma, made up of electrons and ions. In the ocean, people surf by riding their boards at nearly the same speed as the waves. This matching conditio.....»»
Researchers show excited electrons straightening the skewed lattice of perovskite nanocrystals
Researchers from ETH Zurich, Empa and Stanford have taken snapshots of the crystal structure of perovskite nanocrystals as it was deformed by excited electrons. To their surprise, the deformation straightened out the skewed crystal structure rather t.....»»
Superconducting nanowires detect single protein ions
An international research team led by quantum physicist Markus Arndt (University of Vienna) has achieved a breakthrough in the detection of protein ions: Due to their high energy sensitivity, superconducting nanowire detectors achieve almost 100% qua.....»»
Nature inspires a new wave of biotechnology
Biological molecules called peptides play a key role in many biological activities, including the transport of oxygen and electrons. Peptides consist of short chains of amino acids, the building blocks of proteins. They are also the inspiration for n.....»»
MacBook Air gets solid-state active cooling in intriguing demo
Proof-of-concept explores alternative to fans for sustained, heavy workloads. Enlarge / The active cooling chips are labeled and located in the upper-left corner near a custom heatsink in the 15-inch MacBook Air. What.....»»
The best Lenovo gaming laptops you can buy right now
Lenovo's Legion range of gaming notebooks offer solid design and effective cooling solutions, making them a worthwhile choice......»»
Theoretical work indicates that the future Electron Ion Collider can be used to measure the shape of atomic nuclei
Scientists have developed a new way to study the shapes of atomic nuclei and their internal building blocks. The method relies on modeling the production of certain particles from high-energy collisions of electrons with nuclear targets. Such collisi.....»»
Applying semiconductor manufacturing principles to optoelectronic devices
Optoelectronics detect or emit light and are used in a variety of devices in many different industries. These devices have historically relied on thin transistors, which are small semiconductors that control the movement of electrons and photons made.....»»
AirJet cooling system could make a MacBook Air perform like a MacBook Pro
A solid-state cooling system called AirJet was able to cool an M2 MacBook Air enough to keep with the M2 MacBook Pro when running a demanding benchmark test over a sustained period. The bad news is that the system isn’t available for sale to con.....»»
Living in a +50°C world: Cooling must be considered critical infrastructure, says new report
Experts from the University of Birmingham are calling for global cooling and cold chain to be considered as critical infrastructure as the planet continues to heat......»»
New method for identifying bacteria more easily
Far too many antibiotics are used around the world. As a result, bacteria are becoming resistant to these drugs. Curing bacterial diseases is becoming more difficult than before because antibiotics are perhaps our foremost weapons in the fight agains.....»»
Study show extracellular vesicles can also deliver messages from non-human cells
Messenger bubbles produced by human cells can pick up bacterial products and deliver them to other cells, University of Connecticut researchers report in the Nov. 16 issue of Nature Cell Biology. The discovery may explain a key mechanism by which ba.....»»
