Plant scientists have long known that crop yield is proportional to the dose of nitrogen fertilizer, but the increased use of fertilizers is costly and harmful to the environment. Until now, the underlying mechanisms by which plants adjust their growth according to the nitrogen dose has been unknown—a key finding that could help enhance plant growth and limit fertilizer use.

In a new study published in the Proceedings of the National Academy of Sciences (PNAS), plant genomic scientists at New York University’s Center for Genomics & Systems Biology discovered the missing piece in the molecular link between a plant’s perception of the nitrogen dose in its environment and the dose-responsive changes in its biomass.

Taking a novel approach, the NYU researchers examined how increasing doses of nitrogen created changes in plants’ genome-wide expression as a function of time. They then used mathematical models to investigate the rate of change of messenger RNA (mRNA) for thousands of genes within the genome to this experimental set up.

If schedules hold, United Launch Alliance and SpaceX will highlight this weekend with back-to-back rocket launches, a cadence rarely seen on the Space Coast.

First on the Space Force’s calendar is X-37B, a secretive Department of Defense spaceplane that stays in orbit years at a time, testing new systems and capabilities. The 29-foot vehicle will fly on an Atlas V rocket between 6:30 a.m. and 11 a.m. Saturday, though an exact time has not yet been released due to security concerns. Launch Complex 41 will host the attempt.

Though most of the spaceplane’s capabilities are classified, the Space Force said the mission known as Orbital Test Vehicle 6 will host more experiments than ever before. Some of those include testing radiation’s effects on seeds, transforming solar power to transmissible microwave energy, and how space affects different kinds of materials.

Reason has done a great video and article on AI facial recognition, surveillance, etc, and combined it with fashion ideas. It’s created by Zach Weissmueller and Justin Monticello. My interview (as well as others) show up throughout the 11 min video. This is really important watching for the coming future:

Privacy activists say we should be alarmed by the rise of automated facial recognition surveillance. Transhumanist Zoltan Istvan says it’s time to embrace the end of privacy as we know it.

Circa 2015 what about a supercavatating supercarrier :3.

A boat is copying the tech behind a super-fast Russian torpedo by riding a foam tunnel through the water.

Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object’s wake, greatly reducing its drag while simultaneously helping it avoid detection.

The idea originated at Duke University in 2011 when researchers outlined the general concept. By matching the acceleration of the surrounding water to an object’s movement, it would theoretically be possible to greatly increase its propulsion efficiency while leaving the surrounding sea undisturbed. The theory was an extension of the group’s pioneering work in metamaterials, where a material’s structure, rather than its chemistry, creates desired properties.

Six years later, Yaroslav Urzhumov, adjunct assistant professor of electrical and computer engineering at Duke, has updated the theory by detailing a potential approach. But rather than using a complex system of very small pumps as originally speculated, Urzhumov is turning to electromagnetic fields and the dense concentration of charged particles found in saltwater.

Pionic helium exists for long enough to be zapped by lasers, paving the way for more precise measurements of the pion’s mass.

Crucially, plasma treatment of the old rats reduced the epigenetic ages of blood, liver and heart by a very large and significant margin, to levels that are comparable with the young rats. According to the six epigenetic clocks, the plasma fraction treatment rejuvenated liver by 73.4%, blood by 52%, heart by 52%, and hypothalamus by 11%. The rejuvenation effects are even more pronounced if we use the final versions of our epigenetic clocks: liver 75%, blood 66%, heart 57%, hypothalamus 19%. According to the final version of the epigenetic clocks, the average rejuvenation across four tissues was 54.2%.

Researchers have demonstrated that epigenetic age can be halved in rats by using signals commonly found in the blood.

Linking multiple copies of these devices may lay the foundation for quantum computing.

Once unimaginable, transistors consisting only of several- atom clusters or even single atoms promise to become the building blocks of a new generation of computers with unparalleled memory and processing power. But to realize the full potential of these tiny transistors — miniature electrical on-off switches — researchers must find a way to make many copies of these notoriously difficult-to-fabricate components.
