The Expedition 72 crew studied micro-algae and DNA-like nanomaterials on Tuesday to improve health in space and on Earth. The orbital residents also worked on cargo transfers and lab maintenance aboard the International Space Station.

NASA Flight Engineer Nick Hague began his day processing radiation-resistant samples of Arthrospira C micro-algae and stowing them in an incubator for analysis. The samples will be exposed to different light intensities to observe how they affect the micro-algae’s cell growth and oxygen production. Results may advance the development of spacecraft life support systems and fresh food production in space.

Afterward, Hague joined Commander Suni Williams of NASA for a different research session mixing water with samples of messenger RNA, or mRNA, and protein to create DNA-like nanomaterial products inside the Kibo laboratory module’s Life Science Glovebox. Flight Engineer Butch Wilmore then transferred the samples, exposed them to ultrasonic waves, and imaged them with a spectrophotometer to measure the intensity of light at different wavelengths and evaluate the quality of the nanomaterials. The samples will also be returned to Earth for further evaluation. Results may lead to improved therapies for Earth and space health conditions as well as advance the space economy.

A team of cybersecurity researchers at Stony Brook University has uncovered a new way for scammers to steal from unsuspecting cryptocurrency users. They have posted a paper to the arXiv preprint server describing the new crypto scam and how users can protect themselves.

Cryptocurrency is a type of digital currency run on a secure online platform. One example is Coinbase. Crypto currency is stored in a crypto wallet. In this new study, the team in New York reports that scammers have found a way to get people to redirect crypto payments away from intended recipients and toward wallets held by the scammers.

The researchers call the scam typosquatting. It involves setting up Blockchain Naming Systems (BNS) that are similar to those used by well-known entities. It exploits the use of simple word-based addresses rather than the complicated and hard-to-remember letter and digit codes commonly associated with crypto wallets.

Researchers at Rice University have found a new way to improve a key element of thermophotovoltaic (TPV) systems, which convert heat into electricity via light. Using an unconventional approach inspired by quantum physics, Rice engineer Gururaj Naik and his team have designed a thermal emitter that can deliver high efficiencies within practical design parameters.

The research could inform the development of thermal-energy electrical storage, which holds promise as an affordable, grid-scale alternative to batteries. More broadly, efficient TPV technologies could facilitate renewable energy growth—an essential component of the transition to a net-zero world. Another major benefit of better TPV systems is recouping from industrial processes, making them more sustainable. To put this in context, up to 20–50% of the heat used to transform raw materials into consumer goods ends up being wasted, costing the United States economy over $200 billion annually.

TPV systems involve two main components: photovoltaic (PV) cells that convert light into electricity and thermal emitters that turn heat into light. Both of these components have to work well in order for the system to be efficient, but efforts to optimize them have focused more on the PV cell.

Artificial intelligence holds the potential to bring a commercial and economic rebirth for the United States and its allies. Yet the U.S. Congress is getting skittish. Its leaders are reportedly negotiating a lame-duck bill to regulate the AI industry.

As officials push and prod on the new technology, they should exercise caution.

Could AGI be here by 2025? In a shocking new interview, Sam Altman — OpenAI’s CEO — just dropped some MAJOR revelations about their path to artificial general intelligence.

Unlike his usual careful corporate speak, Sam appears surprisingly confident about what’s ahead.

In this video, I break down Sam’s latest statements, OpenAI’s five-level roadmap to AGI, and why this matters for YOU.

After working full-time in AI since January 2023 and studying these developments closely, I’ll give you my analysis on:

Supported, in part, by NASA and administrated by Resources for the Future, Kevin Boyle and colleagues from Moravian University, Penn State, and the University of Rhode Island have assessed the feasibility of implementing a smartphone app designed to convey cholera risk forecasts to households to mitigate the threat of cholera in Bangladesh. This forms part of early warning measures.

The research is titled “Early warning systems, mobile technology, and cholera aversion: Evidence from rural Bangladesh,” and it appears in the Journal of Environmental Economics and Management.

For the research, the team developed CholeraMap, an Android-based smartphone application that conveys cholera risk forecasts to households. The app enables users to access risk predictions – from low to medium to high – for both their community and individual home locations.
