The modular design approach allows taller turbines to be made using wood that also weighs less, meaning more can be made with less material.
Larger turbine structures use more steel which is carbon carbon-intensive process and goes against the idea of using renewable energy.
If aliens were to be in touch tomorrow, humanity would be ill-prepared, scientists warn — something that needs to change as soon as possible.
In the Lord of the Rings, there was “one ring to rule them all.” Now, a team of researchers is developing their own single ruler, an approach to CAR T-cell therapy that could treat all forms and types of blood cancer.
In experiments in mouse models of different blood cancers, the treatment rapidly eliminated tumors, including in mice with acute myeloid leukemia (AML), a difficult-to-treat type of blood cancer for which researchers have struggled to develop effective immunotherapies.
There was also no evidence of serious side effects in the animals. And, finally—and distinctly from the standard approach to current CAR T-cell therapies—it provided the mice with a healthy supply of new blood cells.

On every count, nanoelectrofuel flow batteries appear to beat lithium-ion batteries for use in EVs and larger systems. Influit expects that its current generation of nanoelectrofuel, together with the entire ecosystem needed to produce, distribute, and recycle the fuel that the company is building around it, should cost $130/kWh when used in an EV. In comparison, lithium-ion batteries cost around $138/kWh. True, lithium-ion’s costs should drop below $100/kWh in a few years, but Influit expects its next-generation nanoelectrofuel to fall even further, to around $50 to $80/kWh. That next-gen system should have 5 times the energy density of present Li-ion systems.
Here’s what that means for an EV.
A typical EV battery today occupies about the same volume as would a flow battery with 400 liters of nanelectrofuel. If nanoparticles made up 30 percent of the weight of that fuel, the EV would have a range of only 105 km. Raise that to 40 percent, and the range would climb to 274 km. At 50 percent, it hits 362 km. And at 80 percent, it’s 724 km (450 miles). And that’s all assuming the flow battery’s tank remains the same size.
Facing a power wall and the limit of physics, chip makers are in a constant battle to reengineer and re-evaluate ways to build a better CPU.
NEW YORK (AP) — Nearly three years after rioters stormed the U.S. Capitol, the false election conspiracy theories that drove the violent attack remain prevalent on social media and cable news: suitcases filled with ballots, late-night ballot dumps, dead people voting.
Experts warn it will likely be worse in the coming presidential election contest. The safeguards that attempted to counter the bogus claims the last time are eroding, while the tools and systems that create and spread them are only getting stronger.
Gen DT Thompson ought to be proud of United States Space Force accomplishments during his tenure. Also, I remember his forward-leaning thoughts on establishing a new service as a guest speaking at my Space 300 Course in early 2019. At the time, the rank and file response was to maintain the status quo and not create a Space Force.
The James Webb Space Telescope recently trained its sights on unusual and enigmatic Uranus, an ice giant that spins on its side. Webb captured this dynamic world with rings, moons, storms, and other atmospheric features—including a seasonal polar cap. The image expands upon a two-color version released earlier this year, adding additional wavelength coverage for a more detailed look.
With its exquisite sensitivity, Webb captured the dim inner and outer rings of Uranus, including the elusive Zeta ring—the extremely faint and diffuse ring closest to the planet. It also imaged many of the planet’s 27 known moons, even seeing some small moons within the rings.
In visible wavelengths as seen by Voyager 2 in the 1980s, Uranus appeared as a placid, solid blue ball. In infrared wavelengths, Webb is revealing a strange and dynamic ice world filled with exciting atmospheric features.
