Hmmm; there is another use for this type of satellite just can’t openly state.

SHANGHAI—China launched a satellite to monitor its greenhouse gas emissions early on Thursday, the latest step in efforts to cut its carbon footprint, the official Xinhua news agency said.

The launch follows the United States joining China in formally ratifying the Paris agreement to curb climate-warming emissions. It also comes as large sections of northern China have been shrouded in near-record levels of air pollution for most of the past week, disrupting flights, closing factories and schools, and forcing authorities to issue red alerts.

Nice.

Scientists have enlisted the exotic properties of graphene, a one-atom-thick layer of carbon, to function like the film of an incredibly sensitive camera system in visually mapping tiny electric fields in a liquid. Researchers hope the new method will allow more extensive and precise imaging of the electrical signaling networks in our hearts and brains.

The ability to visually depict the strength and motion of very faint electrical fields could also aid in the development of so-called lab-on-a-chip devices that use very small quantities of fluids on a microchip-like platform to diagnose disease or aid in drug development, for example, or that automate a range of other biological and chemical analyses. The setup could potentially be adapted for sensing or trapping specific chemicals, too, and for studies of light-based electronics (a field known as optoelectronics).

It may be possible to reduce, stop or even prevent absence seizures, the most common form of childhood epilepsy, according to a study published in the leading scientific journal Neuron.

Using an advanced technology called optogenetics and a rodent model, researchers at Stanford University School of Medicine showed that it is possible to trigger seizures by inducing synchronized, rhythmic activity within a particular structure in the brain called the thalamocortical tract. Importantly, they also demonstrated that disrupting this activity is sufficient to terminate the seizures.

For the study the team, led by Dr Jeanne Paz, inserted a gene that encodes for a light-sensitive cell-surface protein into a set of nerve cells situated in the thalamocortical tract of rat and mice models of absence seizures. This way, the scientists were able to prevent these cells from firing by shining a yellow light onto them.

Michigan State University scientists have engineered “molecular Velcro” into to cyanobacteria, boosting this microalgae’s biofuel viability as well as its potential for other research.

The findings, featured in the current issue of ACS Synthetic Biology, show how MSU researchers have designed a surface display system to attach cyanobacteria, also known as blue-green algae, to yeast and other surfaces. The proof-of-concept may improve the efficiency of harvesting algae as well as open avenues to improve the construction of artificial microbial communities for sustainable biofuel production or other industrial projects.

“Inadequate cyanobacterial toolkits limited our ability to come up with biological solutions,” said Derek Fedeson, MSU graduate student and the study’s co-lead author. “So, we wanted to add another tool to the toolbox to expand the capacity of these bacteria, which can harness solar energy for the production of useful compounds.”

Herbs treating Tuberculosis.

A centuries-old herbal medicine, discovered by Chinese scientists and used to effectively treat malaria, may help treat tuberculosis and slow the evolution of drug resistance.

A new study shows the ancient remedy artemisinin stopped the ability of TB-causing bacteria, known as Mycobacterium tuberculosis, to become dormant. This stage of the disease often makes the use of antibiotics ineffective.

What are the unique properties of diamond that make it a supermaterial?

Diamond has long been known to have exceptional properties, largely resulting from the symmetry of the cubic lattice made of light carbon atoms connected by extremely strong bonds. These exceptional properties include thermal conductivity five times higher than that of copper and the widest optical transparency of any material extending from the UV to the RF part of the electromagnetic spectrum. Additionally, diamond also has some interesting chemical properties as it is extremely inert, though it can become a conductor by adding boron. In this manner, one could leverage synthetic diamond for use in electrochemical incineration where existing electrode materials have only a limited lifetime.

Researchers used nitrogen-doped graphene quantum dots to convert carbon dioxide into liquid hydrocarbons like ethylene and ethanol for use as fuel.

The wonder material known as graphene may have a new trick up its sleeve: converting carbon dioxide into liquid fuels. A team of researchers at Rich University in Texas used nitrogen-doped graphene quantum dots (NGQDs) as a catalyst in electrochemical reactions that create ethylene and ethanol, and the stability and efficiency of the material is close to common electrocatalysts such as copper.

In the fight to slow climate change, reducing the amount of carbon dioxide that enters the atmosphere is crucial, and plenty of research is looking into how we can capture carbon at the source, using clay, engineered bacteria, metal-organic frameworks, or materials like the “Memzyme” and sequester it into rock and concrete. Other studies are focusing on converting the captured carbon into liquid hydrocarbons, which can be used as fuel.

For the first time, MIT physicists have observed a highly ordered crystal of electrons in a semiconducting material and documented its melting, much like ice thawing into water. The observations confirm a fundamental phase transition in quantum mechanics that was theoretically proposed more than 80 years ago but not experimentally documented until now.

The team, led by MIT professor of physics Raymond Ashoori and his postdoc Joonho Jang, used a spectroscopy technique developed in Ashoori’s group. The method relies on electron “tunneling,” a quantum mechanical process that allows researchers to inject electrons at precise energies into a system of interest—in this case, a system of electrons trapped in two dimensions. The method uses hundreds of thousands of short electrical pulses to probe a sheet of electrons in a semiconducting material cooled to extremely low temperatures, just above absolute zero.

With their tunneling technique, the researchers shot electrons into the supercooled material to measure the energy states of electrons within the semiconducting sheet. Against a background blur, they detected a sharp spike in the data. After much analysis, they determined that the spike was the precise signal that would be given off from a highly ordered crystal of electrons vibrating in unison.
