                                  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.

Videoclipul fabricii de umanoizi din China se cufundă înapoi în valea neobișnuită PDF Imprimare

                                  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.

Furios? Vasele tale de sânge plătesc prețul, demonstrează un nou studiu PDF Imprimare

                            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.

T. Rex nu a fost atât de inteligent pe cât ni s-a făcut să credem PDF Imprimare

                                     We still wouldn't call a T. rex not that clever to their face

     While we don't like to talk ill of the dead, new physiological analysis has found that the king of the dinosaurs was not so smart after all. It upends previous research that last year likened the brain and neuronal composition of the Tyrannosaurus rex to that of a primate.
    It's been a rough year or two for the long extinct dinosaur. First, we questioned their teeth, finding that those iconic chompers could very much have been smaller and hidden behind lips, and now an international team of paleontologists, behavioral scientists and neurologists have concluded that the T. rex wasn't smarter than your average lizard or crocodile. Why all the hate, science?

                       The 2024 AI Index report highlights what needs to change about AI

    Outperforming humans is one thing, but its rapid rise has meant that AI has created some problems for itself – and we're nervous.

Last week, we discussed AI's incredible evolution in terms of its performance against humans. Almost across the board, AI has surpassed humans in a range of performance-based tasks, necessitating the development of new, more challenging benchmarks. Arguably, that degree of development could be classed as a 'good.' This follow-up article discusses the not-so-good that has resulted from AI's rapid evolution.

The recently released 2024 AI Index report by Stanford University’s Institute for Human-Centered Artificial Intelligence (HAI) comprehensively examines AI's global impact. The seventh edition of the annual report has more content than previous editions, reflecting AI's rapid evolution and growing significance in our everyday lives.

Written by an interdisciplinary team of academic and industrial experts, the 500-page report provides an independent, unbiased look at the health of AI. We've already spoken about the 'good' – now it's time to tackle the bad and the ugly.

With AI now integrated into many facets of our lives, it must be responsible for its contribution, especially to important sectors like education, healthcare, and finance. Yes, the addition of AI can provide advantages – optimizing processes and productivity, discovering new drugs, for example – but it also carries risks.
