Knowing which proteins are key to protection from disease, and the deficiencies in expression or activity that are hallmarks of disease, can inform individualized medicine and the development of new therapies.

Twenty years after the release of the human genome, the genetic “blueprint” of human life, an international research team, including the University of British Columbia’s Chris Overall, has now mapped the first draft sequence of the human proteome.

Their work was published Oct. 16 in Nature Communications and announced today by the Human Proteome Organization (HUPO).

A team of New York University scientists has developed a method using holographic imaging to detect both viruses and antibodies. The breakthrough has the potential to aid in medical diagnoses and, specifically, those related to the COVID-19 pandemic.

“Our approach is based on physical principles that have not previously been used for diagnostic testing,” explains David Grier, a professor of physics at NYU and one of the researchers on the project, which is reported in the journal Soft Matter. “We can detect antibodies and viruses by literally watching them stick to specially prepared test beads.”

If fully realized, this proposed test could be done in under 30 minutes, is highly accurate, and can be performed by minimally trained personnel. Moreover, the method can test for either the virus (current infection) or antibodies (immunity).

Leiden chemists Marc Koper and Ian McCrum have discovered that the degree to which a metal binds to the oxygen atom of water is decisive for how well the chemical conversion of water to molecular hydrogen takes place. This insight helps to develop better catalysts for the production of sustainable hydrogen, an important raw material for the chemical industry and the fuel needed for environmentally friendly hydrogen cars. Publication in Nature Energy.

For years there has been a heated debate in the literature: how to speed up the electrochemical production of hydrogen on platinum electrodes in an alkaline environment? Chemist Ian McCrum watched from the sidelines and concluded that part of the debate was caused by the fact that the debaters were looking at slightly different electrodes, making the results incomparable. Time to change that, McCrum thought, who was a LEaDing Fellow postdoc in the group of Professor Marc Koper at the time.

Astronomers at the University of Iowa have determined our galaxy is surrounded by a clumpy halo of hot gases that is continually being supplied with material ejected by birthing or dying stars. The halo also may be where matter unaccounted for since the birth of the universe may reside. Photo courtesy of Christien Nielsen/Unsplash.

Our Interstellar Boundary Explorer launched to space 12 years ago today!

IBEX studies our solar system’s boundary to interstellar space by measuring particles that rocket back towards Earth from the edge of the heliosphere, the vast bubble generated by the Sun’s magnetic field that envelops all the planets. Scientists recently used an entire solar cycle’s worth of data to explore how this boundary changes throughout the Sun’s activity cycles. https://www.nasa.gov/feature/goddard/2020/nasa-ibex-charts-1…sphere-sun

On this day in 1899, Robert Goddard first considered the concept of space flight, which his work would later help make a reality.

On this particular fall afternoon at age 17, he was sent to prune a cherry tree in his backyard. While he worked, he found himself imagining, as he later wrote in his diary, “how wonderful it would be to make some device which had even the possibility of ascending to Mars, and how it would look on a small scale, if sent up from the meadow at my feet.”

It was at that moment that Robert Goddard dedicated himself to making space flight a reality. As he was to recall later, “I was a different boy when I descended the tree from when I ascended for existence at last seemed very purposive.”

NASA hopes it can grab 60g of the Bennu asteroid in just 10 seconds.

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 F_c[ρ_q] does not suppress the effect. We shall investigate this problem numerically in the near future.
