Reaching superconductivity layer by layer
Imagine a sheet of material just one layer of atoms thick—less than a millionth of a millimeter. While this may sound fantastical, such a material exists: it is called graphene and it is made from carbon atoms in a honeycomb arrangement. First synt.....»»
Examining the function of salmon cooling stations
You've heard of the salmon run: upon reaching sexual maturity, wild Atlantic salmon, which are born in freshwater rivers but spend most of their adult life in the ocean, swim upstream all the way back to their birthplace to spawn. This remarkable mig.....»»
A self-wrinkling coating for impact resistance and mechanical enhancement
Polymer coating is widely used as a protective layer in various fields such as surface anti-corrosion, anti-penetration and anti-impact. How to enhance the mechanical properties of coatings such as impact resistance is important but challenging, unde.....»»
Mysterious fast radio bursts might be caused by “starquakes,” study finds

High-performance SERS substrate proposed based on 2H-TaS2 and single-atom-layer gold clusters
Recently, a research team led by Professor Yang Liangbao from Institute of Health and Medical Technology, Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS) proposed an electromagnetic field enhancement mechanism based on.....»»
Increase in forest fires may damage the crucial ozone layer
All particles that reach the atmosphere cause different chemical reactions. Particles come partly from natural sources such as volcanic eruptions and forest fires, and partly from pollution and emissions. Aerosol researcher Johan Friberg studies part.....»»
Study reveals relationship between spatiotemporal variations of freezing index and permafrost degradation
The freezing index (FI) is a crucial factor for calculating the temporal and spatial distribution of permafrost and the thickness of the active layer in a permafrost region. Understanding the variation in thermal conditions of the permafrost active l.....»»
Meta-learning helps to estimate oceanic barrier layer structure
The oceanic barrier layer is situated between the base of the ocean's density mixed layer and the top of the isothermal layer, with its thickness fluctuations directly influencing the ocean's vertical mixing process. Changes in the barrier layer impa.....»»
Thousands of Android devices come with unkillable backdoor preinstalled
Somehow, advanced Triada malware was added to devices before reaching resellers. Enlarge (credit: gremlin via Getty Images) When you buy a TV streaming box, there are certain things you wouldn’t expect it to do......»»
Free-space nanoprinting beyond optical limits to create 4D functional structures
Two-photon polymerization is a potential method for nanofabrication to integrate nanomaterials based on femtosecond laser-based methods. Challenges in the field of 3D nanoprinting include slow layer-by-layer printing and limited material options as a.....»»
Parker makes its closest and fastest solar flyby
The Parker Solar Probe is the little engine that just keeps going and going by the sun. On September 27th, it made its 17th close approach and skimmed just 7.26 million kilometers (4.51 million miles) above the sun's "surface" layer (called the photo.....»»
Lynxes and vultures offer insights for European wildlife conservation
EU research is providing the most far-reaching analysis of efforts to boost wild-cat populations and aiding scavengers that help balance the ecosystem......»»
New path for early human migrations through a once-lush Arabia contradicts a single "out of Africa" origin
Our species, Homo sapiens, migrated out of Africa multiple times—reaching the Levant and Arabia between 130,000 and 70,000 years ago, as exemplified by human fossils and archaeological sites found at various locations......»»
Navigating moiré physics and photonics with band offset tuning
When two lattices with distinct angles or periodicities come together, they conjure a moiré superlattice—a realm where astonishing phenomena like superconductivity and optical solitons spring to life. At the heart of this realm lies the moiré fla.....»»
Superconductivity at room temperature remains elusive a century after Nobel Prize for landmark discovery
On April 8, 1911, Dutch physicist Heike Kamerlingh Onnes scribbled in pencil an almost unintelligible note into a kitchen notebook: "near enough null.".....»»
Research reveals how a single enzyme can boost soybean oil production
As a potent source of protein and oil, soybeans are a vital global crop for food, animal feed, industrial applications, and biofuel production. Even minor improvements in soybean seed content can therefore have far-reaching implications for agricultu.....»»
Physicists coax superconductivity and more from quasicrystals
In research that could jumpstart interest into an enigmatic class of materials known as quasicrystals, MIT scientists and colleagues have discovered a relatively simple, flexible way to create new atomically thin versions that can be tuned for import.....»»
Apple"s long-term demand for 3nm chips may be lower than expected
Analyst Ming-Chi Kuo believes that weakness in Apple hardware demand through 2024 is causing a ripple effect that is reaching chip manufacturers, with orders for equipment falling by 30% in the next year.15-inch MacBook AirIn a post on Medium on Wedn.....»»
