SpaceX will become the co-owner of valuable data, biological samples, and possibly even patents and intellectual property related to human spaceflight, according to the terms and conditions of a new program inviting research on crewed Dragon missions.

The company started quietly inviting proposals “for exceptional science and research ideas that will enable life in space and on other planets,” to be executed on orbit using its Dragon spacecraft capsule. Specifically, SpaceX says it’s looking for research studies and experiments focused on fitness, or solutions to increase “efficiency and effectiveness,” and those focused on human health during long-duration spaceflight missions.

Selected research study groups would have access to SpaceX’s crewed Dragon missions, opening up a whole new use case for one of the company’s core products.

The rare condition posterior cortical atrophy (PCA) involves strange, troubling issues with vision and spatial awareness – including difficulty judging distances, seeing movement, and recognizing objects – and a new study highlights its close relationship to Alzheimer’s disease in more detail than ever before.

PCA and Alzheimer’s have long been linked with each other, because they share a lot of the same pathological changes in the brain. However, the rarity of PCA has made it hard for researchers to fully assess it in relation to Alzheimer’s.

To address that, an international team of researchers analyzed data on 1,092 individuals with PCA, finding that it was a very strong predictor for Alzheimer’s: in 94 percent of cases, tell-tale Alzheimer’s brain changes were observed, and were most likely contributing to PCA.

Scientists want to send a swarm of small umbrellas into space to block the Sun’s warming ways from reaching the Earth’s surface.

Summary: Researchers developed the world’s first 3D-printed brain tissue that grows and behaves similarly to natural brain tissue, marking a significant leap forward for neurological and neurodevelopmental disorder research.

This novel 3D-printing technique uses a horizontal layering approach and a softer bio-ink, allowing neurons to interconnect and form networks akin to human brain structures.

The ability to precisely control cell types and arrangements provides unparalleled opportunities to study brain functions and disorders in a controlled environment, offering new avenues for drug testing and understanding brain development and diseases like Alzheimer’s and Parkinson’s.

By better taming the Jekyll-and-Hyde nature of an alternative to the semiconductor—one that transitions from electricity-resisting insulator to current-conducting metal—Nebraska’s Xia Hong and colleagues may have unlocked a new path to smaller, more efficient digital devices. The team reports its findings in the journal Nature Communications.

The semiconductor’s ability to conduct electricity in the Goldilocks zone—poorer than a metal, better than an insulator—positioned it as the just-right choice for engineers looking to build transistors, the tiny on-off switches that encode the 1s and 0s of binary. Apply some voltage to the control knob known as a gate insulator, and the semiconductor channel allows electric current to flow ; remove it, and that flow ceases.

Millions of those nanoscopic, semiconductor-based transistors now coat modern microchips, switching on and off to collectively process or store data. But as minuscule as the transistors already are, the demands of consumers and competition continue pushing electrical engineers to shrink them even further, either for the sake of squeezing in more functionality or downsizing the devices that house them.

Heartbeat-induced pulsations of cerebral blood vessels can directly entrain neuronal activity.

Saskatchewan’s capital city is moving forward with plans to electrify its Regina Transit fleet, signing a five-year contract with Nova Bus to acquire 53 battery electric city buses.

A subsidiary of the Volvo Group based in Quebec, Nova Bus manufactures long-range electric bus options with absolutely massive battery packs — up to 564 kWh on its biggest models, with the option of DC fast-charging or charging through overhead wires.

The first installment of its larger order will see seven of its LFSe+ 40-foot, long-range buses delivered to the City of Regina early in 2025 at a cost of $10.8 million (Canadian). The city will follow that with 13 more buses later in 2025 at a cost of $22.4 million, with an additional $21.2 million set to be spent on facility upgrades and infrastructure to support the electric buses.

After topping Tesla in the final three months of 2023, BYD is starting the year off strong with EV sales rising another 50% in January.

BYD sold 105,304 fully electric cars last month, up 48% from the 71,338 handed over last year. Production was also up significantly, with 114,365 EVs built last month, up 64% YOY.

Interestingly, BYD’s all-electric vehicles are beginning to outpace its plug-in hybrids (PHEVs). BYD’s PHEV sales were up 21% to 95,715 last month. Production was only up 9% to 90,749 units.
