The discovery could open the door to new treatments for obesity and type 2 diabetes.
In a breakthrough at CERN
Established in 1954 and headquartered in Geneva, Switzerland, CERN is a European research organization that operates the Large Hadron Collider (LHC), the largest particle physics laboratory in the world. Its full name is the European Organization for Nuclear Research (French: Organisation européenne pour la recherche nucléaire) and the CERN acronym comes from the French Conseil Européen pour la Recherche Nucléaire. CERN’s main mission is to study the fundamental structure of the universe through the use of advanced particle accelerators and detectors.
The European Space Agency is slated to launch a satellite in 2030 that’s meant to probe the nature of dark matter.
A journey of a billion miles and back begins with a launch.
OSIRIS-REx’s goal: Travel to asteroid Bennu, collect a sample, and return it home. But why Bennu? Meet the NASA Explorers looking for clues to our early solar system in a sample of asteroid rock.
It’s not rockets and satellites that make NASA soar. It’s people. Go inside the space agency and follow the pioneers, risk-takers and experts at the frontline of exploration. This season, follow along with the OSIRIS-REx team, as they launch a spacecraft to an asteroid, collect a sample of Bennu, and bring it home to Earth.

Cutting 1 teaspoon of salt from your diet each day can lower your top blood pressure reading just as much as a typical hypertension medication, even if you don’t have high blood pressure, a new study found.
A teaspoon of salt is 2,300 milligrams — that’s the top daily limit for people over 14 recommended by the latest U.S. nutritional guidelines. However, the American Heart Association recommends a diet with less than 1,500 milligrams of sodium a day.
Swooping magnetic fields that confine plasma in doughnut-shaped fusion facilities known as tokamaks could help improve the efficiency of complex machines that produce microchips. This innovation could lead to more powerful computers and smart phones, near-essential devices that make modern society possible.
Engineers use high-energy light emitted by plasma, the electrically charged fourth state of matter, to create small structures on the surfaces of silicon wafers during their transformation into microchips. These tiny components enable a range of devices, including consumer electronics, video games, medical machinery, and telecommunications. Improving the generation of this light could extend the life of vital parts within the machines and make the manufacture of microchips more efficient.
“These findings could change the microchip industry,” said Ben Israeli, lead author of the paper publishing the results in Applied Physics Letters. Israeli is a graduate student in the Princeton Program in Plasma Physics, based at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), which is managed by Princeton University.
The quest to understand our physical universe may depend on investigating our own mind.

An hypothesized term to fix a small mathematical inconsistency predicted electromagnetic waves, and that they had all the properties of light that were observed before and after him in the Nineteenth Century. Unwittingly, he also pointed science inexorably in the direction of the special theory of relativity
My last two articles, two slightly different takes on “recipes” for understanding Electromagnetism, show how Maxwell’s equations can be understood as arising from the highly special relationships between the electric and magnetic components within the Faraday tensor that is “enforced” by the assumption that the Gauss flux laws, equivalent to Coulomb’s inverse square force law, must be Lorentz covariant (consistent with Special Relativity).
From the standpoint of Special Relativity, there is obviously something very special going on behind these laws, which are clearly not from the outset Lorentz covariant. What i mean is that, as vector laws in three dimensional space, there is no way you can find a general vector field that fulfills them and deduce that it is Lorentz covariant — it simply won’t be so in general. There has to be something else further specializing that field’s relationship with the world to ensure such an in-general-decidedly-NOT-Lorentz covariant equation is, indeed covariant.
