Chemists have taken another major step in the quest to use carbon-hydrogen bonds to create new molecules, a strategy that aims to revolutionize the field of organic synthesis.

The journal Nature is publishing the work by chemists at Emory University. They demonstrated the ability to selectively functionalize the unreactive carbon-hydrogen (C-H) bonds of an alkane without using a directing group, while also maintaining virtually full control of site selectivity and the three-dimensional shape of the produced.

“The catalyst control we have found goes beyond what has been achieved before,” says Huw Davies, an Emory professor of organic chemistry whose lab led the research. “We’ve designed a catalyst that provides a huge shortcut for how chemists can turn a simple, abundant molecule into a much more complex, value-added molecule. We hope this gives people a fundamentally new view of what can be achieved through C-H functionalization.”

Not good; hope we can by 2045 have new methods to create weather/ drought resistant vegetation, and matured the improved options around converting sea water to fresh water so no one suffers from harsh weather including droughts.


Longer, hotter, more regular heat waves could have a damaging effect on life expectancy and crop production in Africa warn climate scientists in a study published in the journal Environmental Research Letters. Examining temperature data from 1979 to 2015, the researchers caution that heat waves classified as unusual today could become a normal occurrence within 20 years. This scenario could be triggered by an increase in average global temperature of 2 degrees.

Risk all year round

Located between the Tropic of Cancer and the Tropic of Capricorn, Africa experiences high levels of solar radiation all year round and heat waves can occur in any season, not just during summer months. Running climate models through to 2075, the scientists found that so-called unusual heat waves could occur as frequently as four times per year towards the end of the century. In other words, one dangerously hot spell for every season of the year.

“ALL ABOARD” the QC train is leaving the station.


If you’ve ever had a train set, you might remember the tiny street lamps that are often part of the model landscape. Today, the bulbs from those toy lamps are helping to shed light on quantum computing.

In fact, there’s been a spate of developments lately in quantum computing, and not just IBM’s announcement of its upcoming cloud service. Here are three recent advances from research institutions around the world.

NEW YORK: A team of US researchers has come up with a rough map of part of the brain that controls vision and leaves things out even when they are plainly in sight.

The frontal cortex is often seen as our “thinking cap,” associated with thinking and making decisions. But it’s not commonly connected with vision.

At a time when the global technology giants are set to leverage the benefits of AI for your daily lives, India seems to be reluctant to get on to this bus.

Scientists have devised a way to build a “quantum metamaterial” — an engineered material with exotic properties not found in nature — using ultracold atoms trapped in an artificial crystal composed of light. The theoretical work represents a step toward manipulating atoms to transmit information, perform complex simulations or function as powerful sensors.

The research team, led by scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley, proposes the use of an accordion-like atomic framework, or “lattice” structure, made with laser light to trap atoms in regularly spaced nanoscale pockets. Such a light-based structure, which has patterned features that in some ways resemble those of a crystal, is essentially a “perfect” structure — free of the typical defects found in natural materials.

Researchers believe they can pinpoint the placement of a so-called “probe” atom in this crystal of light, and actively tune its behavior with another type of laser light (near-infrared light) to make the atom cough up some of its energy on demand in the form of a particle of light, or photon.

Nice list of experts on Quantum; however, I would love to see someone from the Lab from Los Alamos to discuss Quantum Internet and University of Sydney from their Innovation Lab or the lady herself “Michelle Simmons” on the panel. Hope to see registration soon.


The announcement was made at the Global Derivatives Trading & Risk Management conference in Budapest, Hungary.

“Quantum computers enable us to use the laws of physics to solve intractable mathematical problems,” said Marcos de López de Prado, Senior Managing Director at Guggenheim Partners and a Research Fellow at Lawrence Berkeley National Laboratory’s Computational Research Division. “This is the beginning of a new era, and it will change the job of the mathematician and computer scientist in the years to come.”

As de Prado points out on the Quantum for Quants website, “Our smartphones are more powerful than the systems used by NASA to put a man on the moon.”

A strange new behavior of water molecules has been observed inside crystals of beryl, a type of emerald, caused by bizarre quantum-mechanical effects that let the water molecules face six different directions at the same time.

Under normal conditions, the two hydrogen atoms in each water molecule are arranged around the oxygen atom in an open “V” shape, sometimes compared to a boomerang or Mickey Mouse ears.

But in a new experiment, scientists have found that hydrogen atoms of some water molecules trapped in the crystal structure of the mineral beryl become “smeared out” into a six-sided ring. [T he Surprisingly Strange Physics of Water].

Last September, researchers detected an exceptionally weak signal that lasted for about a tenth of a second: the gentle chirp of a gravitational wave. This feat, which confirmed a prediction made by Albert Einstein 100 years ago, is worthy of the Nobel prize.

Layout of IBM’s five superconducting quantum bit device. In 2015, IBM scientists demonstrated critical breakthroughs to detect quantum errors by combining superconducting qubits in latticed arrangements, and whose quantum circuit design is the only physical architecture that can scale to larger dimensions. Now, IBM scientists have achieved a further advance by combining five qubits in the lattice architecture, which demonstrates a key operation known as a parity measurement — the basis of many quantum error correction protocols.

IBM Research has announced that effective Wednesday May 4, it is making quantum computing available free to members of the public, who can access and run experiments on IBM’s quantum processor, via the IBM Cloud, from any desktop or mobile device.

IBM believes quantum computing is the future of computing and has the potential to solve certain problems that are impossible to solve on today’s supercomputers.

Exploding polymer-coated gold nanoparticles in the world’s tiniest engine (credit: Yi Ju/University of Cambridge NanoPhotonics)

University of Cambridge researchers have developed the world’s tiniest engine, capable of a force per unit-weight nearly 100 times higher than any motor or muscle.

The new nano-engines could lead to nanorobots small enough to enter living cells to fight disease, the researchers say.

Professor Jeremy Baumberg from the Cavendish Laboratory, who led the research, has named the devices “actuating nanotransducers” (ANTs). “Like real ants, they produce large forces for their weight,” he quipped.
