Building on the moon and Mars? You’ll need extraterrestrial cement for that

Posted by in categories: chemistry, engineering, habitats, space travel

Sustained space exploration will require infrastructure that doesn’t currently exist: buildings, housing, rocket landing pads.

So, where do you turn for construction materials when they are too big to fit in your carry-on and there’s no Home Depot in outer space?

“If we’re going to live and work on another planet like Mars or the moon, we need to make concrete. But we can’t take bags of concrete with us—we need to use local resources,” said Norman Wagner, Unidel Robert L. Pigford Chair of Chemical and Biomolecular Engineering at the University of Delaware.

A groundbreaking power-generating system delivers electricity to an Air Force Base electrical grid

Posted by in categories: energy, engineering

For the first time ever, electricity is delivered through heated supercritical carbon dioxide.

The method has so far succeeded in adding 10 kilowatts to the grid.

Researchers were inspired by elevators to create the system.

Human cognition-enhancing CORD7 mutation increases active zone number and synaptic release

Posted by in categories: biotech/medical, engineering, neuroscience, singularity

This article tells of possible way to increase brain intelligence through a certain mutation which in theory could be altered for biological singularity like effects in the future.


Humans carrying the CORD7 (cone-rod dystrophy 7) mutation possess increased verbal IQ and working memory. This autosomal dominant syndrome is caused by the single-amino acid R844H exchange (human numbering) located in the 310 helix of the C2A domain of RIMS1/RIM1 (Rab3-interacting molecule 1). RIM is an evolutionarily conserved multi-domain protein and essential component of presynaptic active zones, which is centrally involved in fast, Ca2+-triggered neurotransmitter release. How the CORD7 mutation affects synaptic function has remained unclear thus far. Here, we established Drosophila melanogaster as a disease model for clarifying the effects of the CORD7 mutation on RIM function and synaptic vesicle release.

To this end, using protein expression and X-ray crystallography, we solved the molecular structure of the Drosophila C2A domain at 1.92 Å resolution and by comparison to its mammalian homolog ascertained that the location of the CORD7 mutation is structurally conserved in fly RIM. Further, CRISPR/Cas9-assisted genomic engineering was employed for the generation of rim alleles encoding the R915H CORD7 exchange or R915E, R916E substitutions (fly numbering) to effect local charge reversal at the 310 helix. Through electrophysiological characterization by two-electrode voltage clamp and focal recordings we determined that the CORD7 mutation exerts a semi-dominant rather than a dominant effect on synaptic transmission resulting in faster, more efficient synaptic release and increased size of the readily releasable pool but decreased sensitivity for the fast calcium chelator BAPTA.

Meet ‘Copernicus’: TAE’s planned billion-degree, hydrogen-boron nuclear fusion reactor

Posted by in categories: climatology, engineering, nuclear energy, sustainability

TAE’s latest backers include the likes of Google and Chevron

TAE has earned the backing of forward-thinking investors and, so far, has raised a total of $1.2 billion for its commercial fusion development thanks to a track record of exceeding milestones and performance capability. TAE’s mission is to provide a long-term solution to the world’s rapidly increasing electricity demand while ensuring global energy independence and security.

To that end, the company recently closed its Series G-2 financing round, in which it secured $250 million from investors in the energy, technology, and engineering sectors. By avoiding carbon and particulate emissions, TAE’s safe, non-radioactive method minimizes any negative effects on the environment or the effects of climate change.

Digital security dialogue: Leveraging human verification to educate people about online safety

Posted by in categories: education, engineering, ethics, internet, security

Online safety and ethics are serious issues and can adversely affect less experienced users. Researchers have built upon familiar human verification techniques to add an element of discrete learning into the process. This way users can learn about online safety and ethics issues while simultaneously verifying they are human. Trials show that users responded positively to the experience and felt they gained something from these microlearning sessions.

The internet is an integral part of modern living, for work, leisure, shopping, keeping touch with people, and more. It’s hard to imagine that anyone could live in an affluent country, such as Japan, and not use the internet relatively often. Yet despite its ubiquity, the internet is far from risk-free. Issues of safety and security are of great concern, especially for those with less exposure to such things. So a team of researchers from the University of Tokyo including Associate Professor Koji Yatani of the Department for Electrical Engineering and Information Systems set out to help.

Bill Gates’ Strange Plan to Dim the Sun

Posted by in categories: bitcoin, climatology, engineering, sustainability

Bill Gates is funding more research into dimming the sun! Check out how solar geoengineering works.


Bill Gates is a man who recently suggested the world should eat 100% synthetic beef, has argued that bitcoin is bad for the planet, co-founded Microsoft, and remains one of the richest people in the world.

He is also very interested in dimming the light from the sun to reduce or delay the effects of climate change, according to a forthcoming study from the Bill Gates-backed Harvard University Solar Geoengineering Research Program — which aims to evaluate the efficacy of blocking sunlight from reaching our planet’s surface.

Locusts can detect cancer in humans

Posted by in categories: biotech/medical, chemistry, engineering, neuroscience

Earth.com


A new study led by Michigan State University (MSU) has found that locusts can reliably detect through smell a variety of human cancers. The insects can not only “smell” the difference between healthy and cancerous cells, but they can also distinguish between different cancer cell lines. These findings could provide a basis for devices which use locust sensory neurons to enable the early detection of cancer by using only biomarkers in a patient’s breath.

“Noses are still state of the art,” said study senior author Debajit Saha, an assistant professor of Biomedical Engineering at MSU. “There’s really nothing like them when it comes to gas sensing. People have been working on ‘electronic noses’ for more than 15 years, but they’re still not close to achieving what biology can do seamlessly.”

Quantum control for advanced technology: Past and present

Posted by in categories: engineering, mathematics, quantum physics

One of the cornerstones of the implementation of quantum technology is the creation and manipulation of the shape of external fields that can optimize the performance of quantum devices. Known as quantum optimal control, this set of methods comprises a field that has rapidly evolved and expanded over recent years.

A new review paper published in EPJ Quantum Technology and authored by Christiane P. Koch, Dahlem Center for Complex Quantum Systems and Fachbereich Physik, Freie Universität Berlin along with colleagues from across Europe assesses recent progress in the understanding of the controllability of quantum systems as well as the application of quantum control to quantum technologies. As such, it lays out a potential roadmap for future .

While quantum optimal control builds on conventional control theory encompassing the interface of applied mathematics, engineering, and physics, it must also factor in the quirks and counter-intuitive nature of quantum physics.
