                     The first-ever coffee concrete sidewalk is now being put to the test

     We regularly report on potentially industry-changing developments in the materials space, but it’s not often that we see them put to practical use. RMIT has partnered with a local Victorian government council, the Macedon Ranges Shire Council, to lay organic waste-enhanced concrete sidewalks (or 'footpaths' as they're called Down Under) in a world-first trial. Two types of concretes – one made with coffee biochar and one with wood chip biochar – were laid alongside standard concrete, which will act as a control.

                                  Amprius takes the next step toward a more powerful, field-ready wearable battery

Ultra-high density battery vests give next-gen soldiers twice the energy

     Amprius began shipping its remarkable silicone-anode batteries in 2022, laying claim to the world's highest-density battery cells along the way. It's now focusing attention on a unique use case: a military-spec wearable battery for warfighters.

       The idea is simple enough; soldiers of the future will need to carry maximum energy at minimal weight to feed the host of mission-critical electrical hardware they'll wear, stash and carry by hand through the field. Amprius claims its ultra-dense batteries will double the runtime of existing solutions, enabling soldiers to stay out longer without needing to stop for recharge.

                                  Still frame from a video shot inside a humanoid robot factory in China

    A 20-second video from inside a Chinese humanoid robot factory is causing some consternation today around social media. It shows a range of highly realistic-looking, partially skinned humanoids under construction.
    The video, uploaded by user 'meimei4515,' is uncredited, but shows several moving androids with human-like hair and skin – in stark contrast to most of the general-purpose humanoids we'd normally cover, which are designed to look like robots, rather than trying to fool anyone.
Here, there are rows of pretty cyborg-ladies, disembodied heads on stands, fully human-like presenter types wearing shirts and pants, and a surreal tree of humanoid arms, flexing and twirling their white-fingered hands in concert. It looks for all the world like a grittier version of Westworld's backstage workshop.

                            Anger is never a great look, especially inside your blood vessels

     Even brief periods of anger caused by triggering memories can negatively impact our blood vessels' ability to relax. That's the finding of a new study that could have implications on how we look at heart attack and stroke risk.
    While there have been observational studies in the past linking negative emotions like anger to an increased risk of heart attacks, scientists working with the American Heart Association wanted to see if they could more precisely pin down how an experience of anger actually affects our blood vessels and the cells lining them.

So they recruited 280 healthy adults with an average of 26 years to participate in a study in which they were asked to sit quietly and relax for 30 minutes before moving to the next step. Then, researchers took their blood pressure, heart rate, measured their dilation of their blood vessels using finger probes, and took blood samples. Next, the participants were assigned an emotional task based on their place in one of four randomly assigned groups.
