University of Rochester researcher receives $1 million grant to study quantum thermodynamics.
It’s still more science fiction than science fact, but perfect energy efficiency may be one step closer due to new research at the University of Rochester.

The third-order term Fpot(ρ)[ρq] Fpot(ρ)[ρq] above corresponds to the third-order energy in the structural expansion for electron systems. This energy plays an important role in the structural stability of metallic hydrogen 16 (Z= 1). This is because the kernel (10) has a strong wave-vector dependence, which cannot properly be treated in the square-gradient type theory. This brings a special stability of the structure in which as many equilateral triangles with q=3kF appear in the reciprocal lattice. It requires an anisotropic structure or a periodic modulation of the lattice for an atomic phase of hydrogen. Another possibility is to form a crystal with two ions in a unit cell (molecular phase). In any case, the atomic phase of bcc structure would not be realized just under the melting line as log as the third order term in Fc[ρq] does not suppress the effect. We shall investigate this problem numerically in the near future.

An asteroid with a diameter the size of a refrigerator could strike the Earth the day before the November election, according to celebrity scientist Neil deGrasse Tyson — but it’s not large enough to do any serious damage.
The famed astrophysicist said the space rock, known as 2018VP1, is hurtling towards Earth at a speed of 25,000 miles per hour and may clip the planet on Nov. 2.

Pfizer has already made “several hundred thousand doses” of a potential coronavirus vaccine as it prepares to seek emergency use in the US by November.
The drugmaker told the Mail on Sunday that scientists in its main British lab have also unearthed drugs that could provide a potential complete cure for COVID-19, as opposed to merely a preventative vaccine.
The firm’s UK boss, Ben Osborn, said the company is manufacturing the huge stockpile of its current vaccine candidate in Belgium “at risk and at scale,” calling it “tremendously exciting.”
Flippy can cook 19 items, including Impossible Burgers, chicken wings, and hash browns, replacing the need for staff to do so.
In November 2018, after an epic, 41-year voyage, Voyager 2 finally crossed the boundary that marked the limit of the Sun’s influence and entered interstellar space. But the little probe’s mission isn’t done yet — it’s now sending home information about the space beyond the Solar System.
And it’s revealing something surprising. As Voyager 2 moves farther and farther from the Sun, the density of space is increasing.
It’s not the first time this density increase has been detected. Voyager 1, which entered interstellar space in 2012, detected a similar density gradient at a separate location.
