How Coating Cities in White and Blue Paint Can Lower Global Temperatures

Posted by in category: habitats

Painting playgrounds blue to reflect visual and infrared sunlight to reduce surface temperatures to fight the urban heat island effect.


Painting roofs white is seen as a way to reduce surface and building interior temperatures. Using blue paint adds infrared reflectivity.

Meta-mutants! This is what AI thinks humans look like in the metaverse

Posted by in category: robotics/AI

Artificial intelligence has produced creepy images of what it thinks humans will look like in the metaverse.

Craiyon AI, a popular text-to-image system, created several different pictures of what people might look like if humans all join the metaverse. Each has an augmented reality headset merged with their face.

A number of tech companies, including Mark Zuckerberg’s Meta, are pouring billions of dollars to create virtual worlds where people will be able to shop, work and be entertained.

New heat-tolerant, high-capacity capacitor created with solid electrolytes borrowed from all-solid-state batteries

Posted by in categories: chemistry, climatology, sustainability, wearables

Capacitors are energy storage devices—consisting of two electrodes and an electrolyte—that are capable of rapid charging and discharging because of charge adsorption and desorption properties at the electrode-electrolyte interface. Because capacitors’ energy storage does not involve chemical reactions, their storage capacity is lower than that of lithium-ion batteries, but they are useful for power leveling for renewable energy that requires repeated charging at high currents, regenerative braking energy for trains and electric or hybrid cars, as well as instantaneous voltage drop compensation devices that prevent equipment failure due to lightning strikes. They are also expected to be used to store energy for wearable devices in the near future.

Most capacitors use a liquid electrolyte with a low boiling point, which can only be used at temperatures below 80℃. Ceramic capacitors that use solid inorganic materials as a dielectric can be used at temperatures above 80℃, but their is much lower than liquid electrolyte capacitors, which limits their use to electronic circuits.

To increase the energy storage of capacitors, it is necessary to have a large contact area at the interface between the electrode and the electrolyte. Making a large contact area is difficult using ; so, the creation of a capacitor with high storage capacity that can also operate at high temperatures has been desired for a long time.

How Does the TARDIS Work?

Posted by in categories: media & arts, space travel, time travel

The TARDIS is the iconic time machine and spacecraft from the popular sci-fi series Doctor Who. The TARDIS functions by folding space using technology that taps into higher dimensions. But is there any scientific basis for this?

AI Allows Dead Woman to Talk to People Who Showed Up at Her Funeral

Posted by in category: robotics/AI

Marina Smith, a 87-year-old woman who passed away in June, was able to address the mourners at her own funeral in the UK — sort of, at least, thanks to the power of artificial intelligence.

The woman was able to surprise the guests at the funeral in the form of a “holographic conversational video experience,” created by a startup called StoryFile.

The company was founded by Smith’s LA-based son Stephen and was originally created to preserve the memories of Holocaust survivors.

Australia turns gold mine into physics lab to study dark matter

Posted by in category: cosmology

A gold mine located over half a mile (one km) underground in Victoria, Australia, has been converted into the Stawell Underground Physics Laboratory to study dark matter, a press release from Australia’s Nuclear Science and Technology Organization (ANSTO) said.

Scientists believe that dark matter, the invisible substance largely unknown to mankind, makes up 85 percent of our universe’s mass. To know more about it, scientists have been building dark matter detectors, and one of the “most sensitive” detectors delivered some significant results last month.

Nvidia Details Grace Hopper CPU Superchip Design: 144 Cores on 4N TSMC Process

Posted by in category: computing

Nvidia shared more performance benchmarks, but as with all vendor-provided performance data, you should take these numbers with a grain of salt. These benchmarks also come with the added caveat that they are conducted pre-silicon, meaning they’re emulated projections that haven’t been tested with actual silicon yet and are “subject to change.” As such, sprinkle some extra salt.

Nvidia’s new benchmark here is the score of 370 with a single Grace CPU in the SpecIntRate 2017 benchmark. This places the chips right at the range we would expect — Nvidia has already shared a multi-CPU benchmark, claiming a score of 740 for two Grace CPUs in the SpecIntRate2017 benchmark. Obviously, this suggests a linear scaling improvement with two chips.

AMD’s current-gen EPYC Milan chips, the current performance leader in the data center, have posted SPEC results ranging from 382 to 424 apiece, meaning the highest-end x86 chips will still hold the lead. However, Nvidia’s solution will have many other advantages, such as power efficiency and a more GPU-friendly design.
