NASA has announced an updated plan to continue New Horizons’ mission of exploration of the outer solar system.

Beginning in fiscal year 2025, New Horizons will focus on gathering unique heliophysics data, which can be readily obtained during an extended, low-activity mode of operations.

While the science community is not currently aware of any reachable Kuiper Belt object, this new path allows for the possibility of using the spacecraft for a future close flyby of such an object, should one be identified. It also will enable the spacecraft to preserve fuel and reduce operational complexity while a search is conducted for a compelling flyby candidate.

AUSTIN (KXAN) — As the City of Austin works toward reducing its carbon footprint, city officials are working to expand programs and infrastructure to help make electric vehicle technology more accessible citywide.

Amy Atchley, senior lead with Austin Energy’s EV equity program, spoke Tuesday at MOVE America 2023, a mobility conference held in downtown Austin. Atchley’s presentation centered around providing EV access to underserved community members, particularly as the city moves toward a 2040 goal of net zero carbon emissions.

With that goal in mind, she noted transportation is the leading emitter of carbon dioxide into the atmosphere. In order to achieve that benchmark, she said the city must have at least 40% of its vehicle miles traveled done via electric vehicle technology by 2030.

The Federal Trade Commission and 17 state attorneys general today sued Amazon.com, Inc. alleging that the online retail and technology company is a monopolist that uses a set of interlocking anticompetitive and unfair strategies to illegally maintain its monopoly power. The FTC and its state partners say Amazon’s actions allow it to stop rivals and sellers from lowering prices, degrade quality for shoppers, overcharge sellers, stifle innovation, and prevent rivals from fairly competing against Amazon.

The complaint alleges that Amazon violates the law not because it is big, but because it engages in a course of exclusionary conduct that prevents current competitors from growing and new competitors from emerging. By stifling competition on price, product selection, quality, and by preventing its current or future rivals from attracting a critical mass of shoppers and sellers, Amazon ensures that no current or future rival can threaten its dominance. Amazon’s far-reaching schemes impact hundreds of billions of dollars in retail sales every year, touch hundreds of thousands of products sold by businesses big and small and affect over a hundred million shoppers.

“Our complaint lays out how Amazon has used a set of punitive and coercive tactics to unlawfully maintain its monopolies,” said FTC Chair Lina M. Khan. “The complaint sets forth detailed allegations noting how Amazon is now exploiting its monopoly power to enrich itself while raising prices and degrading service for the tens of millions of American families who shop on its platform and the hundreds of thousands of businesses that rely on Amazon to reach them. Today’s lawsuit seeks to hold Amazon to account for these monopolistic practices and restore the lost promise of free and fair competition.”

An international research team has made a groundbreaking discovery at the European XFEL X-ray laser, bringing us closer to realizing the potential of atomic clocks.

They achieved this by exciting a highly promising transition in the nucleus of scandium, a readily available element, Deutsches Elektronen-Synchrotron (DESY) announced. This unique resonance demands X-rays with an energy of 12.4 kiloelectronvolts (keV), an astonishing 10,000 times the energy of visible light, with a remarkable width of only 1.4 femtoelectronvolts (feV), equivalent to one second in 300 billion years.

Ralf Röhlsberger, a DESY researcher, emphasizes the significance of this achievement: “This corresponds to one second in 300 billion years.” Such precision would redefine the boundaries of timekeeping accuracy.

The process not only shortens the time required for recycling but also reduces secondary waste streams.

The world is expected to experience a surge in battery demand as it moves to renewable energy sources. And, with the development of sustainable energy technologies, there will be a subsequent increase in the demand for precious metals used in batteries. Many of the materials used in such batteries, like lithium-ion batteries, are not available in abundance, and the best way to meet this need is to recycle old batteries.

To aid in this mission, a team of researchers at Rice University in the United States of America has developed a new recycling process that helps salvage more than 98 percent… More.

The new data also confirms that Texas has cemented its position as the crypto capital of the United States, as miners flock there for abundant clean energy and a permissive regulatory environment.

Texas made up 8.43% of the hashrate in the U.S. as of the end of 2021, and that percentage has jumped to 28.50% as of July 27, 2023 — though Foundry notes that the data was aggregated during a period of heavy curtailment in July, so Texas’s percentage of actual hashrate is even greater than what’s reflected on their latest map. Zhang added that Texas’s growth in Foundry’s map also had to do with the fact that the firm took on more clients there in the past two years.

Given that the U.S. is currently the world leader in terms of its share of the collective hashrate of the bitcoin network, that makes Texas the bitcoin capital of the world.

Imagine a juggler tossing balls into the air. The art of juggling is a dance between motion and pause, where the ball’s speed slows as it ascends, and then quickens on the way down. This dance reveals one of the core tenets of physics: conservation laws.

Simply put, these laws tell us that certain features of our world, like energy, don’t just vanish; they transform from one form to another. In our juggling example, the energy of motion (kinetic energy) morphs into the energy of position (potential energy) and back again.

Conservation laws aren’t just limited to juggling, or even Earth for that matter. They’re universal principles, true across various fields of physics. Yet, they aren’t always straightforward.

Researchers unveil a revolutionary material, tungsten oxide hydrate, enabling dynamic windows that adapt to light and temperature, boosting energy efficiency.

Dynamic windows have long been the dream of architects and engineers, promising buildings that adapt to varying light and temperature conditions.

Now, researchers from NC State University have taken a giant leap forward in this field by unveiling a revolutionary material known as tungsten oxide hydrate. This innovation could pave the way for the next generation of dynamic windows, offering building occupants the ability to switch their windows between three distinct modes: transparency, infrared light blocking, and glare control, according to a university release.

There is a largely untapped energy source along the world’s coastlines: the difference in salinity between seawater and freshwater. A new nanodevice can harness this difference to generate power.

A team of researchers at the University of Illinois Urbana-Champaign has reported a design for a nanofluidic device capable of converting ionic flow into usable electric power in the journal Nano Energy. The team believes that their device could be used to extract power from the natural ionic flows at seawater-freshwater boundaries.

“While our design is still a concept at this stage, it is quite versatile and already shows strong potential for energy applications,” said Jean-Pierre Leburton, a U. of I. professor of electrical & computer engineering and the project lead. “It began with an academic question—’Can a nanoscale solid-state device extract energy from ionic flow?’—but our design exceeded our expectations and surprised us in many ways.”
