Turbulences theory closer high-energy physics than previously thought

Many scientists have been disappointed that no new elementary particles have been discovered at CERN's Large Hadron Collider since the Higgs Boson in 2012. The failure to detect particles that had previously been predicted by theory is only one example of a 'hole' that has recently appeared in the concept of naturalness in theoretical physics. In simple terms, the concept states that physical parameters should depend roughly equally on all the terms used to calculate them, in terms of proportion.

Understanding stock market returns: Which models fits best?

Understanding stock market returns hinges on understanding their volatility. Two simple but competing models have been dominant for decades: the Heston model, introduced in 1993, and the multiplicative model, which dates back to 1990. American physicists recently compared the two models by applying them to the United States stock market and using historical data from two indexes: the S&P500 and Dow Jones Industrial Average.

Long range intrinsic ferromagnetism in two-dimensional materials

A collaborative FLEET study has reviewed recent progress in 2-D ferromagnetism, and predict new, possible 2-D ferromagnetic materials.

Stable majorities

How could prebiotic information-bearing DNA sequences survive in the face of competition from a vast excess of shorter molecules with random sequences? LMU scientists now show that a relatively simple mechanism could have done the trick.

Dark Matter is Real. "Dark Matter" is a Terrible Name for It

Astronomers have been grappling with the mystery of dark matter for a long time, and I mean a looong time. The history of dark-matter investigations goes back at least to 1906, when physicist Henri Poincaré's 1906 speculated about the amount of “matière obscure” in the Milky Way. Or really, it goes to back to 1846 and the first successful detection of dark matter: the discovery of the planet Neptune, whose existence had been inferred by its gravitational pull well before it was actually obse

How to ice-proof the next generation of aircraft

To prevent ice formation on aircraft during flight, current systems utilize the heat generated by burning fuel, but these high-temperature, fuel-dependent systems cannot be used on the proposed all-electric, temperature-sensitive materials of next-generation aircraft. As some scientists search for new anti-icing methods, some have taken a different approach. They've published evidence showing that equipment important in controlling landing and takeoff can double-up as icing control. It depends on plasma actuators.

Gender parity: Not a foregone conclusion in all fields

Women constitute approximately 47 percent of the workforce yet they are still underrepresented at the highest levels of business, government, medical and academic hierarchies.

'Featherweight oxygen' discovery opens window on nuclear symmetry

Researchers at Washington University in St. Louis have discovered and characterized a new form of oxygen dubbed "featherweight oxygen"—the lightest-ever version of the familiar chemical element oxygen, with only three neutrons to its eight protons.

Putting a new spin on Majorana fermions

Scientists have proposed a new method for producing more robust Majorana fermions, a kind of quasiparticle that could act as stable bits of information in next-generation quantum computers.
