With striking high-speed video footage, scientists have for the first time detailed how predatory mosquito larvae attack and capture prey in aquatic habitats. Published in the Annals of the Entomological Society of America, this new research sheds light on behavior that has long proven too small and too fast to study, until now. In this video, a Psorophora ciliata larva strikes a prey larva via a sudden neck extension to launch its head away from its body and toward the prey.

After more than three years circling the Earth, the Planetary Society’s LightSail 2 mission has come to an end following a fiery reentry. The satellite was an important tech demo for the idea of solar sailing, which could eventually propel spacecraft to other stars.

LightSail 2 was launched aboard a SpaceX Falcon Heavy rocket in June 2019, settling into an initial orbit at an altitude of around 720 km (450 miles). At that height, the Earth’s atmosphere is still thick enough to create drag, which would threaten to eventually pull the spacecraft down.
But that’s where the plucky little satellite’s special ability came in. Although it’s only the size of a shoebox, LightSail 2 unfurled a big reflective sheet, called a solar sail, about the size of a boxing ring. The idea is that photons from sunlight strike this sail and generate tiny amounts of thrust, allowing the craft to change its orbit.

And LightSail 2 demonstrated this concept beautifully. In three and a half years, the spacecraft completed around 18,000 orbits and traveled 8 million km (5 million miles), adjusting its orbit continuously to keep itself aloft. But all good things must come to an end, and sometime on November 17, drag finally won the tug-of-war and pulled the spacecraft back to Earth.

Telegram has launched the ability to buy and sell short recognizable @ usernames for personal accounts, public groups and channels.

The auction for the best usernames is live on Fragment:
https://fragment.com

You can find @science channel name at this auction: https://fragment.com/username/science

The ownership of these collectible usernames is secured in the immutable ledger of TON, a fast and scalable blockchain network. Owners can add multiple username aliases to their personal account, group or channel.

Each collectible name can be accessed with its @username on Telegram, or outside Telegram using links such as science.t.iss.one and t.iss.one/science.

For the first time in the history of social media, people have full ownership of their usernames. Long-time Telegram users who have been using short usernames they registered early on can now benefit from the platform's growth by selling their usernames in fair, transparent, fully decentralized auctions.

In Korea, the temperature in winter sometimes drops to -20 degrees Celsius.

Traditional Korean houses have rather thin walls, mostly made of wood.

So how did they get through such cold winters? That's thanks to a very smart and very efficient underfloor heating system.

There are many heating systems also designed to add to cooking or cooking hot water for bathing. The underfloor heating system is typical of Korea. It dates back to prehistoric times, and so it is embedded in Korean folklore and traditions.
Please discover this interesting video describing this floor heating system. Video with English subtitles.

New research adds to a small but growing body of study investigating the effects of e-cigarette use on oral health

Smoking is no good for your teeth, that is well-known. But what about vaping? New research from Tufts University suggests using e-cigarettes may not be that much better, finding an association between increased risk for cavities and vaping.

In Finland, the temperature reaches -40 ° C in winter, the trees are covered with so much snow and frost that it seems like a landscape from another planet.

Tutankhamun's tomb, discovered by archaeologists in the Valley of the Kings on Nov. 4, 1922, was found loaded with treasures. Some of those artifacts, like his death mask, are widely known. But others, such as a mannequin that may have helped the boy king choose what to wear, are less famous but offer insight into King Tut's life. Here are 30 fascinating treasures from Tutankhamun's tomb and what they reveal about the iconic ancient Egyptian pharaoh 100 years after the discovery of his remains.

Flushed toilets emit aerosols that spread pathogens contained in feces, but little is known about the spatiotemporal evolution of these plumes or the velocity fields that transport them. Using laser light to illuminate ejected aerosols we quantify the kinematics of plumes emanating from a commercial flushometer-type toilet, and use the motion of aerosol particles to compute velocity fields of the associated flow. The toilet flush produces a strong chaotic jet with velocities exceeding 2 m/s; this jet transports aerosols to heights reaching 1.5 m within 8 seconds of initiating a flush. Quantifying toilet plumes and associated flow velocities provides a foundation for future design strategies to mitigate plume formation or to disinfect pathogens within it.

Buckle up because this trip is going to take you from the remote boreal forests of the Arctic to the far landscapes of the Southern Hemisphere, passing by spectacular lakes, mountains, and beaches along the way…always with the Northern Lights dancing in the sky.

The EctoLife Artificial Womb Facility envisages a controversial new way to be pregnant, with the baby growing in an idealized, but completely inhuman environment: transparent "growth pods" arranged by their hundreds in human baby farming operations.

To be clear from the outset: this is just a concept at this stage, the brainchild of Berlin-based "producer, filmmaker and science communicator" Hashem Al-Ghaili. There are no immediate plans to build an EctoLife facility, this is merely a piece of science fiction Al-Ghaili has extrapolated from the current state of fertility research.

Canadian researchers have discovered two minerals never before seen on Earth, in a sample of 15-tonne meteorite found in Somalia, the ninth-largest meteorite ever found. 🪨✨
The new minerals have been named elaliite and elkinstantonite.

Westminster City Council are fighting back against people who urinate in public by treating walls with a pee paint that give perpetrators a nasty surprise if they attempt to relieve themselves on it.
The paint creates a water-repellent layer so that urine and other liquid bounce back onto the perpetrator doing the peeing, leaving them soaked.
