AI helps reduce Amazon hydropower dams’ carbon footprint

Posted by in categories: robotics/AI, sustainability

A team of scientists has developed a computational model that uses artificial intelligence to find sites for hydropower dams in order to help reduce greenhouse gas emissions.

Hydropower dams can provide large quantities of energy with carbon footprints as low as sources like solar and wind. But because of how they’re formed, some dams emit dangerously high levels of greenhouse gases, threatening sustainability goals.

With hundreds of currently proposed for the Amazon basin—an ecologically sensitive area covering more than a third of South America—predicting their in advance could be critical for the region, and the planet.

Student discovers unusual new mineral inside a diamond

Posted by in category: chemistry

A Ph.D. student at the University of Alberta has discovered a new and curious mineral inside a diamond unearthed from a mine in South Africa.

The —named goldschmidtite in honor of Victor Moritz Goldschmidt, the founder of modern geochemistry—has an unusual chemical signature for a mineral from Earth’s mantle, explained Nicole Meyer, a in the Diamond Exploration Research and Training School.

“Goldschmidtite has high concentrations of niobium, potassium and the rare earth elements lanthanum and cerium, whereas the rest of the mantle is dominated by other elements, such as magnesium and iron,” said Meyer.

EV battery cooling technology to cut range anxiety

Posted by in categories: engineering, government, transportation

The i-CoBat project, operating under the UK government’s Faraday Battery Challenge, aims to create an electric vehicle (EV) battery pack which is cooled through immersion using MIVOLT, a biodegradable cooling fluid developed by specialist manufacturer M&I Materials, the project’s leader. Warwick Manufacturing Group (WMG), the manufacturing research arm of the University of Warwick, along with engineering consultancy Ricardo plc, are partnering with M&I to optimise the EV battery cooling technology for a longer lasting, safer battery product.


A UK consortium is developing new EV battery cooling technology, with the aim of minimising range anxiety for electric vehicle users.

Instant messaging in proteins discovered

Posted by in category: biotech/medical

Proteins are essential for every living cell and responsible for many fundamental processes. In particular, they are required as bio-catalysts in metabolism and for signaling inside the cell and between cells. Many diseases come about as a result of failures in this communication, and the origins of signaling in proteins have been a source of great scientific debate. Now, for the first time, a team of researchers at the University of Göttingen has actually observed the mobile protons that do this job in each and every living cell, thus providing new insights into the mechanisms. The results were published in Nature.

Researchers from the University of Göttingen led by Professors Kai Tittmann and Ricardo Mata found a way to grow high-quality protein crystals of a human protein. The DESY particle accelerator in Hamburg made it possible to observe protons ( with a positive charge) moving around within the protein. This surprising “dance of the protons” showed how distant sections of the protein were able to communicate instantaneously with each other—like electricity moving down a wire.

In addition, Tittmann’s group obtained high-resolution data for several other proteins, showing in unprecedented detail the structure of a kind of hydrogen bond where two heavier atoms effectively share a proton (known as “low-barrier hydrogen bonding”). This was the second surprise: the data proved that low-barrier hydrogen bonding indeed exists in proteins resolving a decades-long controversy, and in fact plays an essential role in the process.

Application filed by US Secretary of Navy

Posted by in categories: energy, materials

The electromagnetic field generator includes a shell, an electrostatic generator, a power plant, a thermoelectric generator, and an electric motor. The shell has embedded polycrystalline ferroelectric ceramic material which is polarized such that the ceramic material exhibits strong Piezoelectric Effect properties thus inducing high frequency vibrations. The shell may be further doped with radioactive elements which under high frequency vibrations induce gamma ray emission. The electrostatic generator is for charging up the shell and is disposed within the shell. The power plant is to generate thermal power, and is disposed within the sphere. The thermoelectric generator is to convert the thermal power generated by the power plant to electrical energy. The electric motor powered by the electrical energy generated by the thermoelectric generator, and supplies input voltage such that the shell spins at high angular speeds, vibrates at high frequencies, and generates an electromagnetic field.

What came before the Big Bang? A trip through cosmology, multiverses, fifth dimensions and a big bounce

Posted by in categories: cosmology, particle physics

Where were you before you were conceived?

The question itself has no meaning: there was no “you” to be anywhere at all.

Asking questions like “what happened before the Big Bang?” is similarly meaningless.

Identification of maize seeds

Posted by in category: biotech/medical

Varietal purity is the most important quality parameter of maize seeds, which has direct and prominent influence on the output and quality of maize. For the first time, to our knowledge, we present a new kind of terahertz (THz) scanning imaging technology for identification of maize seeds. Terahertz images of DNA samples are obtained by point-by-point scanning imaging technology. Inspection and identification of specific kinds of seeds are realized successfully by using the method of component pattern analysis. In this method, what we need are only data of image and absorption spectral information of samples; no specific features of samples are required. This technology provides a new approach for the detection and identification in biology and it can also be extended to poison inspection.

Daimler Ends Gas Engine Development: Full Focus On Electric Cars

Posted by in categories: sustainability, transportation

Daimler has just announced that it is halting all future development of gasoline engines. The automaker will solely focus on electric cars from here on out. This implies that Mercedes-Benz is taking the same approach.

The future is electric. We all know that and so too does Daimler now with this move to electric-drive only for future vehicles.
