Billions of years ago, Mars could have been a planet very like Earth with copious liquid water on its surface. But over time, that water rose into Mars’s thin atmosphere and evaporated off into space. There are only very small amounts of water vapor left in the atmosphere today, and a new study shows that vapor is being lost even faster than previously believed.

The research, published in the journal Science, used data from the Trace Gas Orbiter in orbit around Mars to see how water moved up and down through the layers of the Martian atmosphere in order to understand how fast it evaporates away. They found that the vapor changes through the seasons and that in the warmer months the atmosphere hosts a whole lot more water than expected, in a state called “supersaturation.”

When the atmosphere becomes supersaturated, this makes the evaporation of water happen even faster. “Unconstrained by saturation, the water vapor globally penetrates through the cloud level, regardless of the dust distribution, facilitating the loss of water to space,” the authors explain. Even when the density of dust or ice particles in the atmosphere changes, that still doesn’t stop supersaturation, so the evaporation of water continues at a brisk pace.

Neuroregeneration entails not only neurogenesis, but also regrowth of lost connections and birth of non-neuronal cells. While adult neurogenesis in humans is only known to occur definitively in a few precisely circumscribed regions of the brain, work in other species suggests that science has only scratched the surface of the full regenerative potential of our own nervous systems.

The serotonergic system has widely been shown to control many aspects of neuroregeneration. In some regions, it facilitates neurogenesis, while in others, it seems to inhibit it. In the case of inhibition, a recent example has been published in PLOS Biology. The authors used a zebrafish model of Alzheimer’s disease to show that amyloid-induced interleukin-4 (IL4) promotes neurogenic stem cell proliferation by suppressing the production of serotonin. In these animals, there is a unique neuro-immune interaction through which IL4 secreted by dying neurons activates microglia. In turn, microglia reciprocate by revving up neural stem cell proliferation.

Uranium contaminated groundwater that is unsafe to drink could be cleaned up using the new remediation technique.

An electrochemical technique could prevent the spread of uranium in contaminated groundwater and provide a new way to source material for use in nuclear fuel.

In October 2019, Google made a big announcement. It announced its 53-qubit quantum computer named Sycamore had achieved ‘quantum supremacy.’ That’s when quantum computers can complete tasks exponentially more quickly than their classical counterparts. In this case, Google said its quantum machine completed a task in 200 seconds that would have taken the world’s most powerful computer 10,000 years to complete. IBM, another major player in quantum computing, took issue with the findings. Either way, it was a big milestone in quantum computing, and it’s leading to a lot of hype in the field. Here’s how quantum computing works, and how it could change everything from Wall Street to Big Pharma and beyond.

SET-listed satellite service provider Thaicom is in talks with three foreign companies on partnership deals to operate ground stations for satellite data transmission as the government works towards opening the satellite industry to private operators through a licensing regime.

The ground stations, known as satellite gateways, are responsible for transmitting data to and from the satellite to the local area network. The antennas and equipment for converting the radio frequency signal to an internet protocol signal for terrestrial connectivity are already installed.

The deals are expected to be concluded this year, with operations kicking off next year, according to Thaicom chief executive Anant Kaewruamgvongs.

One of the new products unveiled at CES this year is a new kind of home security system — one that includes drones to patrol your property, along with sensors designed to mimic garden light and a central processor to bring it all together.

Sunflower Labs debuted their new Sunflower Home Awareness System, which includes the eponymous Sunflowers (motion and vibration sensors that look like simple garden lights but can populate a map to show you cars, people and animals on or near your property in real time); the Bee (a fully autonomous drone that deploys and flies on its own, with cameras on board to live-stream video); and the Hive (a charging station for the Bee, which also houses the brains of the operation for crunching all the data gathered by the component parts).

Roving aerial robots keeping tabs on your property might seem a tad dystopian, and perhaps even unnecessary, when you could maybe equip your estate with multiple fixed cameras and sensors for less money and with less complexity. But Sunflower Labs thinks its security system is an evolution of more standard fare because it “learns and reacts to its surroundings,” improving over time.

A new satellite will provide more detailed information about rising sea levels and other changes in Earth’s oceans. Meet Sentinel-6/Jason-CS.

JNS.org – An Israeli-made machine that creates fresh drinking water from air was named the “Energy Efficiency Product of the Year” in the 2020 Smart Home Mark of Excellence Awards at the Consumer Electronics Show (CES) in Las Vegas on Wednesday.

Presented annually during CES by the Consumer Technology Association, the Mark of Excellence Awards recognize the technology industry’s top smart-home innovations. The water-from-air appliance, named “GENNY,” was manufactured by the Rishon Letzion-based company Watergen.
