NASA’s Juno mission to Jupiter made the first definitive detection beyond our world of an internal magnetic field that changes over time, a phenomenon called secular variation. Juno determined the gas giant’s secular variation is most likely driven by the planet’s deep atmospheric winds.

The discovery will help scientists further understand Jupiter’s interior structure—including atmospheric dynamics—as well as changes in Earth’s magnetic field. A paper on the discovery was published today in the journal Nature Astronomy.

“Secular variation has been on the wish list of planetary scientists for decades,” said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio. “This discovery could only take place due to Juno’s extremely accurate science instruments and the unique nature of Juno’s orbit, which carries it low over the planet as it travels from pole to pole.”

Standard snapshots from space don’t quite show Earth in all its glory. There’s so much more to see.

To reveal details impossible to observe with the naked eye, Rice University engineers are building a portable spectrometer that can be mounted on a small satellite, flown on an airplane or a drone or someday even held in the hand.

Bioengineer Tomasz Tkaczyk and his colleagues at Rice’s Brown School of Engineering and Wiess School of Natural Sciences have published the first results from a NASA-funded project to develop a small, sophisticated spectrometer with unusual versatility. Their paper appears in Optics Express.

Liquids, with their flowing dynamics, are often far from equilibrium. This makes it particularly hard to model processes in soft matter or living tissue, which contain liquids. New research from the University of Tokyo’s Institute of Industrial Science (IIS) offers an elegant approach to modeling the self-organization of out-of-equilibrium systems.

Such systems naturally try to self-organize into more stable states. Colloidal suspensions—homogeneous suspensions of undissolved particles in a liquid, which are widespread in nature—tend to separate out over time if colloids strongly attract with each other. A major difficulty in modeling this process is the complex dynamical interaction between colloids and liquid. The two components have very different dynamics that are hard to unite in a single model.

The IIS study, published in Nature Computational Materials, resolves this through an approach termed fluid particle dynamics (FPD). Instead of being treated as solids, the suspended colloid particles are simulated as undeformable highly viscous liquid droplets. This effectively makes the colloidal suspension a binary liquid mixture, and removes the need for complicated treatment of a solid-liquid boundary condition.

The Giant Magellan Telescope should be observing the heavens by 2026.

What is dark matter made of? It’s one of the most perplexing questions of modern astronomy. We know that dark matter is out there, since we can see its obvious gravitational influence on everything from galaxies to the evolution of the entire universe, but we don’t know what it is. Our best guess is that it’s some sort of weird new particle that doesn’t like to talk to normal matter very often (otherwise, we would have seen it by now). One possibility is that it’s an exotic hypothetical kind of particle known as an axion, and a team of astronomers are using none other than black holes to try to get a glimpse into this strange new cosmic critter.

The Expedition 59 crew is exploring space’s long-term impacts on biology and physics today helping astronauts go to the Moon in 2024. #Moon2024

The six residents aboard the International Space Station kicked off the workweek today exploring microgravity’s long-term impacts on biology and physics. The Expedition 59 crew is also ramping up for a fourth spacewalk at the orbital lab this year.

NASA is planning to send men and women to the Moon in 2024 and life science on the station will help flight surgeons keep lunar astronauts healthy. The space physics research will also provide critical insights to engineers designing future spacecraft and habitats for exploration missions.

CRISPR technology is a simple yet powerful tool for editing genomes. It allows researchers to easily alter DNA sequences and modify gene function.

It has many potential applications include correcting genetic defects, treating and preventing the spread of diseases and improving crops. By delivering the CRISPR enzyme Cas9 nuclease coupled with synthetic guide RNA (gRNA) into a cell, the cell’s genome can be cut at a desired location, that allows existing genes to be removed or add new ones.

And it doesn’t want the details of the case made public.

Elon Musk’s space company is taking the U.S. to court.

On April 29th and 30th, the XPRIZE Foundation hosted an event at its headquarters in Culver City, California that could have a profound effect on the evolving landscape of biorejuvenation research: the Future of Longevity Impact Roadmap Lab.

For those unfamiliar, the XPRIZE Foundation is famous for designing multi-million-dollar, global competitions to incentivize the development of technological breakthroughs, perhaps the most well-known being its first: the Ansari XPRIZE, which offered a $10,000,000 award for the first non-governmental organization to launch a reusable manned spacecraft into space twice within two weeks.

With this event, the purpose of which was to gather subject matter experts to brainstorm a potential longevity-research prize, XPRIZE has turned its focus towards solving the critical problem of age-related diseases on society and extending healthy human lifespan for all. As I was fortunate enough to directly participate in this exciting meeting, I’d like to share some of my experiences with you all.
