The weaponizing of smartphone location data on the battlefield
For soldiers on the battlefield, the act of turning on one’s smartphone has been described as the digital equivalent of lighting a cigarette, as doing so creates a signal about one’s location that can be picked up by the enemy. Despite this, smar.....»»
Researchers find nutrient imbalance in Flathead Lake
As any gardener or farmer can tell you, nitrogen and phosphorus are chemical elements found in soils and fertilizers that plants need to grow. They also know different ratios of nitrogen and phosphorus are ideal or detrimental for different types of.....»»
Physicists Discover a "Family" of Robust, Superconducting Graphene Structures
In 2018, MIT researchers found that if two graphene layers are stacked at a very specific "magic" angle, the twisted bilayer structure could exhibit robust superconductivity, a widely sought material state in which an electrical current can flow thro.....»»
Flashing creates hard-to-get 2D boron nitride
Rice University scientists who "flash" materials to synthesize substances like graphene have turned their attention to boron nitride, highly valued for its thermal and chemical stability......»»

Unusual superconductivity observed in twisted trilayer graphene
The ability to turn superconductivity off and on with a literal flip of a switch in so-called "magic-angle twisted graphene" has allowed engineers at Caltech to observe an unusual phenomenon that may shed new light on superconductivity in general......»»
Tiny lab on a chip analyzes very small volumes of liquid
Scientists from the Institute of Laser Engineering at Osaka University created a prototype terahertz optical spectroscopy system with a sensing area equivalent to the cross-sectional area of just five human hairs. By measuring the shift in peak trans.....»»
"Hot" graphene reveals migration of carbon atoms
The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on the stability of the material.....»»
2D interfaces in future transistors may not be as flat as previously thought
Transistors are the building blocks of modern electronics, used in everything from televisions to laptops. As transistors have gotten smaller and more compact, so have electronics, which is why your cell phone is a super powerful computer that fits i.....»»
New hybrid machine learning forecasts lake ecosystem responses to climate change
Throughout the middle of the 20th century, phosphorus inputs from detergents and fertilizers degraded the water quality of Switzerland's Lake Geneva, spurring officials to take action to remediate pollution in the 1970s......»»

Information energy accounts for dark energy, resolves Hubble tension, avoids the "big chill," and is falsifiable
Stellar heated gas and dust has an entropy, or information content, with an equivalent energy of 1070 joules, directly comparable to the mc2 equivalent energy of the universe baryon mass. In a study published in Entropy, Professor Paul Gough at the U.....»»
Scientists offer solutions to global phosphorus crisis that threatens food and water security
Phosphorus is an essential but often overlooked resource, which is vital for life on Earth and is extracted from phosphate rock for use in crop fertilizers, livestock feeds and food additives. A major new report by scientists warns that global misman.....»»
The secret lives of Darwin"s finches reveal daily commutes equal to the area of 30 soccer fields
Using radio transmitters, scientists have gained new insights into the behavior of medium ground finches in the Galapagos Islands. A study led by McGill University researchers reveals daily movement patterns covering an area equivalent to the size of.....»»
Researchers unveil particle accelerator region inside a solar flare
Solar flares are among the most violent explosions in our solar system, but despite their immense energy—equivalent to a hundred billion atomic bombs detonating at once—physicists still haven't been able to answer exactly how these sudden eruptio.....»»
