Rivian opens its adventure charging network to other EVs today

The first of more than 90 Rivian fast-charging locations opened to other EVs today.

Today, Rivian announced that it is opening up the Rivian Adventure Network of fast chargers to drivers of all other makes of electric vehicles, beginning with its location in Joshua Tree, California. The Joshua Tree Charging Outpost, which has 12 DC fast chargers, is now accessible to any EV with a CCS1 charging port, as well as any Tesla or EV equipped with a native NACS (J3400) port using an adapter. A planned hardware upgrade in the future will add native NACS cables. (Rivian is switching the plugs on its own EVs from CCS1 to NACS in 2025.)

Rivian revealed its plans in early 2021 to build charging stations, a few months before it let us loose in the R1T electric pickup. The Rivian Adventure Network currently has deployed banks of fast chargers at 91 sites across the US, with another 12 in the works. (A separate Rivian Waypoint Network is building out level 2 chargers with J1772 plugs.)

All but one of the Adventure Network sites have at least six DC fast chargers, although until now, all have been the preserve of Rivians alone. In total, the automaker plans to have 3,500 DC fast chargers in the Adventure Network.

Bitcoin hits $100,000

Trump-fueled crypto rally rages on as bitcoin hits new high.

Late Wednesday, bitcoin hit $100,000—a major milestone for the cryptocurrency, which has been experiencing a massive upswing since Donald Trump won the 2024 presidential election.

Trump is a shiny new crypto supporter, launching his own cryptocurrency on the campaign trail and hoping to woo crypto enthusiast voters by promising to slacken the Biden administration's heightened scrutiny of cryptocurrency.

According to CNN, bitcoin's latest record high came shortly after Trump announced his intentions to nominate Paul Atkins to lead the Securities and Exchange Commission (SEC) once Gary Gensler—a noted crypto critic—resigns on Inauguration Day.

E-tattoos could make mobile EEGs a reality

Epidermal electronics attached to the skin via temporary tattoos (e-tattoos) have been around for more than a decade, but they have their limitations, most notably that they don't function well on curved and/or hairy surfaces. Scientists have now developed special conductive inks that can be printed right onto a person's scalp to measure brain waves, even if they have hair. According to a new paper published in the journal Cell Biomaterials, this could one day enable mobile EEG monitoring outside a clinical setting, among other potential applications.

EEGs are a well-established, non-invasive method for recording the electrical activity of the brain, a crucial diagnostic tool for monitoring such conditions as epilepsy, sleep disorders, and brain injuries. It's also an important tool in many aspects of neuroscience research, including the ongoing development of brain-computer interfaces (BCIs). But there are issues. Subjects must wear uncomfortable caps that aren't designed to handle the variation in peoples' head shapes, so a clinician must painstakingly map out the electrode positions on a given patient's head—a time-consuming process. And the gel used to apply the electrodes dries out and loses conductivity within a couple of hours, limiting how long one can make recordings.

By contrast, e-tattoos connect to skin without adhesives, are practically unnoticeable, and are typically attached via temporary tattoo, allowing electrical measurements (and other measurements, such as temperature and strain) using ultra-thin polymers with embedded circuit elements. They can measure heartbeats on the chest (ECG), muscle contractions in the leg (EMG), stress levels, and alpha waves through the forehead (EEG), for example.
