Ledger starts shipping its high-end hardware crypto wallet

Posted by in category: energy

Ledger, a French startup mostly known for its secure crypto hardware wallets, has started shipping new wallets nearly 18 months after announcing the latest Ledger Stax devices.

The updated wallet features an E-Ink display and has been designed in partnership with Tony Fadell, one of the main designers behind the iPod. E-Ink technology is generally used for e-book readers like the Amazon Kindle or the Rakuten Kobo because the displays look good in daylight and don’t require a lot of power.

After fulfilling all preorders, the company will list the Ledger Stax on its website once it has more stock available. The reason the hardware wallet fell behind schedule is the company may have overpromised on the design front. The Ledger Stax features a curved E-Ink display. It said it has been more difficult than expected to produce curved E-Ink displays at scale.

Ford teases new F-150 Lightning-based EV SuperTruck ahead of Pikes Peak [Video]

Posted by in categories: climatology, sustainability

Ford Performance is at it again. The high-performance unit is teasing its new Ford F-150 Lightning-based EV SuperTruck ahead of its official debut. To showcase its abilities, Ford’s new electric SuperTruck will compete in the upcoming Pikes Peak International Hill Climb.

Based on its best-selling electric pickup, Ford’s Performance team tweaked the Lightning-based EV SuperTruck to boost power and aerodynamics.

Ford says running test electric vehicles at Pikes Peak enables it to “push the boundaries of EV powertrains in the most extreme conditions.” The team then relays what it learns to improve Ford’s production vehicles.

Researchers develop new electrode binder material for high-performance sodium-ion batteries

Posted by in categories: energy, materials

Lithium-ion batteries have been at the forefront of energy storage technologies. However, the availability of lithium is limited. Consequently, the growing demand for energy-storage systems has led to the search for low-cost and more accessible materials for rechargeable batteries. Sodium-ion batteries (SIBs) are a promising candidate due to the virtually unlimited sodium (Na) resources in seawater and salt deposits.

Top US coal producer Wyoming just approved a $1.2B solar farm

Posted by in categories: solar power, sustainability

Wyoming just approved its largest solar farm – 771 megawatts (MW) of utility-scale solar plus battery storage.

Developer Enbridge has been issued a siting permit by the Industrial Siting Council to construct and operate Cowboy Solar I & II on private land leases in Laramie County, in the state’s southeast corner. Next steps will be to obtain county, environmental, and municipal permits.

Cowboy Solar I will include 400 MW of solar power and 136 MW of battery storage, while Cowboy Solar II will have 371 MW of solar power and 133 MW of battery storage.

T Cell Activation and Proliferation: The Three Signal Process

Posted by in category: biotech/medical

The immune system provides an integral defense against cancer growth and progression. Activating an anti-tumor immune response relies on several biological steps that can ultimately result in the elimination of tumor cells. T cell activation, a process requiring three “signals,” is required for optimal anti-tumor immunity.

T cells, immune cells generated in the thymus, have a programmed affinity for a specific particle foreign to the body. T cells must become specially “trained” to recognize this foreign protein, known as an antigen. After leaving the thymus, T cells circulate throughout the body in search of their antigen.

Antigen presenting cells (APCs) comprise another category of immune cells required for effective anti-tumor immunity. APCs also circulate the body, where they locate, process, and “present” pieces of antigen on their surface. A surface molecule called a major histocompatibility complex (MHC) holds the antigen on the outside of the APC.
