2022-08-30 17:00:05 In 2024, China will launch the Xuntian space telescope with a field of view 300 times larger than that of the American Hubble, but with the same resolution - 2.5 billion pixels

It will share its orbit with the Chinese space station instead of being at Lagrangian point 2, 1.5 million kilometers away from the planet like James Webb.

For maintenance and instrument replacement, the telescope will be able to dock with the module of the Chinese space station. Its lifetime is 10 years, but with proper care it can last even longer.

The Xuntian will weigh more than 10 tons and carry five scientific instruments: a terahertz module, a multichannel imager, an integral field spectrograph, a planetary coronagraph and a head module.

2022-08-30 14:02:00 Land sharks can roam for two hours on land: how do they do it

Terrestrial sharks - these predators were only to be feared in the water, but now it turns out that there is no rest from them on land.

On the Great Barrier Reef, representatives of "land-walking" sharks were spotted for the first time in 2020. Scientists at Florida Atlantic University said the epaulette shark is the most evolved species known to science.

Scientists have found that spotted predators move on land using their pectoral fins - they act as "legs. To move from one place to another, sharks use their fins to lift their body and push off flat surfaces.

It turned out that both newborn and juvenile sharks initially had the skill to move on land. The mature specimens, able to get their own food, are no longer needed.

The data obtained, according to scientists, in the future will help reveal the secrets of how individual species cope with the effects of abrupt climate change.

In this video, a man with the disease feels his life changing in seconds, thanks to an advanced deep brain stimulation (DBS) technique that makes the right parts of the brain work.

Wonders of science and human ingenuity.

2022-08-30 06:00:03 Invisible coating makes wood "fireproof"

Scientists at Nanyang Technological University in Singapore (NTU Singapore) have invented an invisible coating that makes wood "fireproof" while retaining its natural color.

Without treatment, wood burns easily and ignites. Current methods of protecting wood buildings from fire require the use of fire retardant panels or paint coatings that hide the natural veins of the wood.

The new invisible coating provides a fire barrier, is easy to apply, effective at containing the spread of fire and produces little smoke when burning.

2022-08-29 17:00:06 Worms can help in the treatment of cancer - if you "dress" them in special hydrogel shells containing anti-cancer drugs.

The fact is that some species of tiny worms parasitizing in the human body show an increased interest in cancer cells, which they "smell" from afar. Such couriers can be used to specifically "attack" cancerous tissues.

2022-08-29 14:02:00 Electrical brain stimulation improved memory in older adults

Researchers found that stimulation of the inferior parietal lobes at a selected frequency improved word recall from the end of the list, indicating working memory activation. And stimulation of the dorsolateral prefrontal cortex at 60 hertz affected word recall at the beginning of the list, and this reflected long-term memory performance. Improvements in memory were observed by the third day of the experiment, and the result persisted for one month after electrical stimulation.

2022-08-29 11:00:09 Jetson's CEO flies a personal copter to work.

Jetson has released a video showing the Jetson One eVTOL. In the video, the company's CEO sits in the cockpit of the flying machine and takes a flight to work. He does it as easily and confidently as if he was driving an ordinary car. The video is meant to intrigue, but we can't help but point out that the Jetson One is not yet well suited for real life.

Patan's entire journey takes place in desert terrain, moving dangerously close to trees, probably because the car's flight altitude is severely limited. Takeoff and landing take place in spacious, empty lots of private homes, which has nothing to do with a busy highway or parking lot.

It's worth noting that it's really cool.

2022-08-29 06:00:04 Hiking boots with hydraulic pistons keep hikers' feet from spraining

German startup Terrein won an ISPO award in the second quarter of 2022 and is now preparing to launch the first model of Ascent hiking shoes with ankle protection against sprains.

The Ascent boots feature a pair of hydraulic pistons on either side of the foot that are in a deactivated position when in their standard, safe position. They take the form of elastic straps and do not squeeze the foot. However, as soon as the foot begins to bend beyond the allowable limits, the plunger activates and rigidly fixes the ankle, preventing it from shifting in the wrong direction.
Such a shoe will keep you safe from injury before you even feel anything. This design also applies to medical orthoses. Відкрити / Коментувати

2022-08-28 17:00:04 Jupiter consumed many planets as it grew to gigantic proportions

Although Jupiter is the largest planet in the solar system, we know very little about its inner workings. Telescopes have taken thousands of pictures of swirling clouds in the gas giant's upper atmosphere, but these storms also act as a barrier that keeps us from seeing what's inside this planet.

In a new study, scientists were finally able to look beyond Jupiter's cloud cover using gravity data collected by NASA's Juno space probe. The data allowed astronomers to map the rocky material in the giant planet's core, which revealed a surprisingly high content of heavy elements. The chemical composition suggests that Jupiter devoured nucleating planets, or planetesimals, to build mass during its formation. Відкрити / Коментувати

This is a wet rubber crumb pouring technology used in playgrounds, parks and recreation areas.

The wet-pour system is a two-layer system that includes a cushioned base pad and a colored top. It is often referred to as "rubber asphalt" or "soft asphalt.

Wet pour, sometimes called soft asphalt, has become a popular type of surface for playgrounds and other outdoor areas throughout the United Kingdom. Відкрити / Коментувати
