From chaos to order: Proteins can re-structure themselves to create important substances
The protein "MIPS" changes its internal structure when it becomes active. Its disordered active center becomes a defined structure with special functions. The protein plays a key role in the production of inositol, which is also known as vitamin B8,.....»»
Analysis of heterostructures for spintronics shows how two desired quantum-physical effects reinforce each other
Spintronics uses the spins of electrons to perform logic operations or store information. Ideally, spintronic devices could operate faster and more energy-efficiently than conventional semiconductor devices. However, it is still difficult to create a.....»»
Scientists propose a new method to search for dark matter using LIGO
A new study published in Physical Review Letters (PRL) proposes using gravitational wave detectors like LIGO to search for scalar field dark matter......»»
The memory in seeds: How plants carry environmental clues across generations
Phenotypic plasticity enables plants to adjust their physical traits in response to environmental variations, playing a vital role in their survival and adaptability. While past research has primarily focused on how these traits manifest within a sin.....»»
Photoacoustic sensor achieves high-sensitivity detection of multiple greenhouse gases
Recently, Prof. Gao Xiaoming's team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, developed a novel photoacoustic spectroscopy (PAS)-based sensor that enabled simultaneous, high-sensitive detection of CO2, CH4, and.....»»
Ethanol: A viable alternative to sugar-based carbon sources for biomanufacturing
In a recent review published in Biotechnology for Biofuels and Bioproducts, a research team led by Associated Professor Wang Peng from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with Dr. Rodrigo Lede.....»»
Reinventing the clock: NASA"s new tech for space timekeeping
Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for example, relies on precise timing signals from satellite.....»»
Scientists find new epigenetic switch, revealing how genes are regulated in early development
The team of Professor Christof Niehrs at the Institute of Molecular Biology (IMB) in Mainz, Germany, has discovered that a DNA modification called 5-formylcytosine (5fC) functions as an activating epigenetic switch that kick-starts genes in early emb.....»»
Do bacteria age?
Any organism that lives, grows and reproduces must also age. People often think of aging in the physical sense—gray hair, slowed movements and wrinkles—but aging fundamentally occurs on a molecular level, inside of cells......»»
Black hole pairs may unveil new particles
In a paper published in Physical Review Letters this week, physicists from Amsterdam and Copenhagen argue that close observations of merging black hole pairs may unveil information about potential new particles. The research combines several new disc.....»»
Scientists decipher the energy patterns in our cells
Our cells harness energy for essential functions such as division, wound healing, and our immune response to diseases including cancer. But until now, the mechanics of how that energy affects cell behavior—and how this relates to health outcomes—.....»»
New strategy for simulating nonadiabatic dynamics of molecules at metal surfaces
A research team has proposed a novel approach to accurately describe electron transfer mediated nonadiabatic dynamics of molecules at metal surfaces. Their works were published in Physical Review Letters......»»
Soil pH drives microbial community composition: Study shows how bacteria work together to thrive in difficult conditions
Though a founding concept of ecology suggests that the physical environment determines where organisms can survive, modern scientists have suspected there is more to the story of how microbial communities form in the soil......»»
Energy transmission in quantum field theory requires information: Research finds surprisingly simple relationship
An international team of researchers has found a surprisingly simple relationship between the rates of energy and information transmission across an interface connecting two quantum field theories. Their work was published in Physical Review Letters.....»»
Generating spin currents directly using ultrashort laser pulses
An international team of physicists has found that it is possible to generate spin currents directly using certain kinds of ultrashort laser pulses. In their study, published in the journal Physical Review Letters, the group used a linearly polarized.....»»
Organization of DNA in chromosomes can be explained by weak interactions between nucleosomes, research suggests
An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes......»»
Neural network improves tunable diode laser absorption spectroscopy quantification accuracy
A research group from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences recently developed a neural network-based absorbance recovery method to improve the accuracy of single path tunable diode laser absorption spect.....»»
AirPods 4 tidbits: Secret capacitive button, Vision Pro lossless
Historically, AirPods cases have always had a physical button on the back to initiate pairing with your iPhone. With the announced this week, however, Apple is switching things up. Instead of a physical pairing button, the AirPods 4 case has a hidde.....»»
iPhone 16 Camera Control is about to free up a lot of Action buttons
iPhone 16 and iPhone 16 Pro introduce a new Camera Control button. As I’m thinking about this physical hardware button, it occurs to me that I’m sort of getting an Action button for the first time — despite currently being an iPhone 15 Pro Max.....»»
The PS5 Pro brings the game console’s disc drive era to an end
Sony relegates physical game discs to a peripheral afterthought. Enlarge / Notice anything missing from the one and only model of the PS5 Pro? (credit: Sony) Here at Ars, we've been publicly musing about whether the worl.....»»
