The James Webb telescope captured the first ever star WR140 with incredible resolution.

The rings in the photo are streams of matter that a collapsing star in a pre-supernova state throws out during processes similar to inhalation-exhalation.

Chemists figured out how to make a liquid crystal display out of fish scales.

Japanese chemists have learned how to synthesize carbon nanoonions (CNO) from fish scales. The stable optical properties of scale nanoonions will make it possible to produce large-area flexible radiating films and LED devices. This work opens up new possibilities for the development of next-generation displays.

The drone opened the cupboard and turned the valve.

Swiss engineers taught the drone how to manipulate objects, such as opening cabinets and turning valves. It has 12 propellers that can be rotated so the drone can hover in any position. The complex manipulator was replaced with a simple stick with a hook at the end. Before starting work, the drone builds a trajectory so that the door or other object comes from the current position to the specified one. To do this, engineers hung on objects (and the drone itself) spherical infrared markers - cameras around the perimeter of the room track their position with an accuracy of tenths of a millimeter. Hypothetically, a drone can be trained to handle almost any object that can be pulled or pushed. At the same time, while it is only able to work indoors, which is equipped with a tracking system, and, for example, is not adapted to the street.

In China, they introduced a computer case with an aquarium for fish.

MetalFish has released the Y2 Fish Tank Chassis - and its name speaks for itself. The capacity of the built-in aquarium was 13 liters - this is about half the volume of the body. The kit comes with a filter, a pump and an oxygenator for aeration, which is powered by a USB connector. The manufacturer claims that you can install a Micro-ATX or Mini-ITX board, a video card up to 220 mm in size and a small power supply into the case.

A new species of giant jellyfish has been found off the coast of Papua New Guinea.

Diver Dorian Borcherds photographed a giant translucent jellyfish. Marine biologist Lisa-Anne Gershwin carefully examined the recording and came to the conclusion that it contained a previously unknown species. The discovered jellyfish was described as teardrop-shaped with a pattern on the sides. She is the size of a soccer ball. The new species is similar to the jellyfish Chirodectes maculatus, which was seen in 1997 off the Great Barrier Reef off the coast of Australia. Researchers then captured and studied the animal.

AI discovered alternative physics without human intervention.

A team from Columbia University showed the trained artificial intelligence a set of frames representing typical physical actions - burning, rotating, etc. And then, the algorithm was asked to describe this case with formulas. The AI has successfully completed the task - its formulas are working. But these are generally other formulas that are in no way connected with current physics. There is no breakthrough knowledge for our physics.

In China, a national relic, the Pingnan Wan'an Bridge in the city of Ningde, burned down.

The bridge has over 900 years of history. After a fire, it cannot be restored.

Scientists have discovered episodic memory in dolphins

They conducted an experiment and offered eight dolphins a game - people stood along the edges of the round pool, but only one of them had the ball in their hands. The animals had to swim up to the right person on the first attempt and ask him for a toy. The experiment was carried out for two days. All eight dolphins successfully answered the question "where?", and only one of them did not cope with the question "who?". So the animals demonstrated that they not only remember the event, but also the context accompanying it.

The concentration of "eternal chemicals" in rainwater is exceeded almost all over the world.

Swedish and Swiss scientists have measured the concentrations of four major "timeless chemicals" in rainwater and found that they are well above safe levels almost everywhere in the world. In particular, the norms established in the USA for drinking water. "Eternal Chemicals" (PFAS) is a group of 4.7 thousand artificially synthesized substances. The most famous of them is Teflon. They are used to dye clothing and food packaging; creation of cosmetics; production of dirt- and water-repellent coatings. Ingested PFAS increases the risk of cancer, malformations in newborns, liver and thyroid diseases, and hormone problems.

European birds have faded due to the climate crisis.

The colorful plumage of European birds has faded over the past 15 years due to climate change. This can lead to problems during the mating season - the bright color of birds attracted partners. Color changes can be caused by a combination of a 1.23°C increase in temperature and a 0.64 mm decrease in rainfall. Becoming less bright, the birds adapted to the new environmental conditions. They may now have to change their breeding strategy.

Iceland's Fagradalsfjall volcano erupts for the first time in 6,000 years.

The Icelandic Meteorological Office has urged people to stay away from the volcano. The fact is that the eruption goes through a volcanic crack, and this can lead to strong explosions or significant dispersion of ash in the stratosphere. In addition, in this case, toxic fumes can evaporate.

Xiaomi showed the MiGu headband for controlling smart home devices with the power of thought.

There are three sensors on the headband that register brain signals and convert them into commands. The device can be used not only to control gadgets, but also to detect stress or fatigue while driving a car. The prototype was assembled by the company's employees as part of an annual developer forum dedicated to ideas that may be useful in the future. Not the fact that Xiaomi will undertake to finalize the project.

Because of the abnormal heat, the source of the Thames dried up for the first time.

For the first time in the history of observations, the source of the Thames dried up due to abnormal heat in the city of Cirencester, Gloucestershire. According to the UK Met Office, July 2022 was the driest in England since 1935.

Two glowing Labradors were born in South Korea.

Koreans continue experiments on editing the genome. This time, Labradors were born with strengthened hips and the code cleaned from unnecessary DNA mutations. And at the same time, they added the genome of the green fluorescent protein. Now puppies glow under ultraviolet light.

Xiaomi has released a Korin Zero backpack with a built-in cooling system.

A fan is placed in the back, which rotates at a speed of 3500 rpm and is powered by a power bank. Korin Zero is made of waterproof materials and weighs about 1.5 kg. The volume is 16 liters. There is a compartment for a laptop, mouse and other accessories, a pocket for an umbrella, and a USB in the strap for charging your smartphone on the go. On the Chinese crowdfunding platform Xiaomi Youpin, the backpack costs 499 yuan.

Scientists have come up with proton resistors for an artificial brain.

They are a million times faster than the neurons in the human head. Using simple and affordable compounds of phosphorus and silicon, scientists have created analog logic elements that operate much faster than silicon transistors and a million times faster than synapses in the human brain. The comparison with the brain is not accidental. The neurons in the complex can be quite large, while the new logic elements - proton resistors - can be thousands of times smaller. It will be possible to fit such a powerful analog processor into the volume of the brain that it will be something unimaginable by modern standards. However, many more discoveries remain to be made for this, although the main thing - the basic element - scientists have already invented.
