From algae, they created a luminous material that does not need energy.

For their work, the scientists studied the bioluminescent waves that sometimes appear on the beaches of San Diego during red tides. The light comes from single-celled algae called dinoflagellates. Scientists have found that they begin to glow only under mechanical action. To fabricate the devices, researchers inject a solution of Pyrocystis lunula dinoflagellate into a cavity made of a soft, elastic, transparent material.

A record for cooling a substance in history has been set.

Physicists at the University of Basel have cooled a tiny copper circuit on a silicon chip to 220 microkelvins. This is a record low temperature obtained in such experiments. Almost absolute zero.

Scientists have made malarial mosquitoes fight the disease themselves.

They modified the genes of Anopheles gambiae mosquitoes, the main vectors of malaria in Africa. The researchers modified the insects' digestive process so that two special molecules, so-called antimicrobial peptides, are produced in their intestines. Peptides of "anti-malarial" mosquitoes change their metabolism, shorten their lifespan and impair their ability to transmit the malaria parasite. The first trials showed good results, but scientists will need another two to three years to conduct field studies.

Deadly pneumonia was cured with the help of microrobots.

Researchers at the University of California, San Diego have developed micro-robots that can swim in their lungs. The devices destroyed pneumonia-causing bacteria in the lungs of mice. As a result of treatment, 100% of mice survived, while in the control group, all individuals died. Microrobots are made from algae cells, the surface of which is speckled with nanoparticles filled with antibiotics. The algae provides propulsion, which allows the microrobots to float and deliver antibiotics directly to more bacteria in the lungs.

A pair of drones shared 3D printing duties.

Engineers from four countries have developed a 3D printing system consisting of two drones that perform different functions: one of them is responsible for the printing itself, and the second makes sure that the printed object matches the plan.

Lemurs began to hug trees for cooling.

Sifaki Verro, large lemurs native to Madagascar, have developed a peculiar way to cool off in hot weather. When the air temperature rises above thirty degrees, these primates descend to the ground and hug the cool tree trunks.

Apple is preparing a flexible iPhone with a self-healing screen.

The company has patented "Electronic device with flexible display cover". This confirms that the company is developing a flexible iPhone. What the patent says: - iPhone will get a foldable screen with the display outward - Self-healing material will protect against scratches - The material will be plastic and soft, not glassy. Apple creates many patents. Ideas are not always realized in life, so it is clearly not worth expecting such a device in the near future.

A new island has appeared on Earth.

Since September 10, volcanic eruptions in the islands of Tonga have formed an island of cooled lava measuring 24,000 square meters. Moreover, the island continues to grow - it is already visible from space.

The prototype ion-powered drone lasted more than 4 minutes in the air - it has no propellers at all.

Startup Undefined Technologies announced that it was able to prove the commercial viability of an ion-powered drone project. Having no propellers or any other mechanics, the "silent" Silent Ventus drone lasted 4.5 minutes in the air. Such a device promises to be convenient in the city, where it will not disturb residents with noise during the delivery of goods.

TechRax blogger staged an accident to test the accident sensor in the iPhone 14.

To test the sensor, the enthusiast used a Mercury sedan, which was equipped with a remote accelerator control system, and the mobile device was tied with tape to the headrest of the driver's seat. The vehicle was twice pushed into the carcasses of other vehicles in the field. The accident detector in the smartphone worked - after the accident, the iPhone began to play loud sounds and automatically dial 911.

How much garbage did people leave on Mars?

Chagri Kilic, a robotics researcher at West Virginia University, has calculated that over 50 years of exploring the surface of Mars, humans have left 7,119 kilograms of debris on the planet. Kilich calculated in kilograms the mass of all spacecraft ever sent to the Red Planet and subtracted the weight of the still working - 9979 - 2860 = 7119. In total, there are three main types of debris on Mars - discarded equipment (for example, containment shells of spacecraft), inactive or broken devices.

Hideo Kojima, NASA and Anicorn unveil the Space Ludens watch.

Silver watch with gold accents. Beneath the dial is an engraved NASA inscription, and on the case is the Kojima Productions slogan "From Sapiens to Ludens". They worked on the clock for 2 years. As part of the partnership, Anicorn will also release several accessories, including t-shirts and a detailed wearable Luden mask. Only buyers of a rare edition of watches will be able to get it. In total, the manufacturer will release only 100 of these masks. The watch will go on sale on September 27, 2022. The price of the accessory is not yet known.

Climate warming has accelerated the decomposition of wood by termites.

Biologists have estimated the rate at which termites decompose dead wood in different climates and found that the insects became more active by more than 6.5 times for every 10 degrees Celsius increase in temperature. This means that as termites warm up, they will play an increasingly important role in the carbon cycle, and their populations will spread around the world.

Four-dimensional ultrasound has proven that people react to taste and smell even in the womb.

The study involved a hundred women at 32-36 weeks of pregnancy. On the day of the study, the women were not allowed to eat or drink flavored beverages before visiting the doctor. 20 minutes before the scan, they received a capsule of carrot or cabbage powder. After that, doctors took pictures of the facial expressions of as yet unborn children. Scientists believe that the mother's diet during pregnancy can affect the taste preferences of children. Also, the right diet of a woman is able to form healthy eating habits for a child.

iPhone 14 proved to be more repairable than five previous models.

iFixit dismantled the new Apple flagship and was pleasantly surprised - the design of the phone implies an easier repair. In particular, you can easily remove not only the front of the smartphone with a display, but also the rear glass. This has never happened in the modern history of Apple - now you can approach the replacement of the necessary parts from two sides.

The Greenwich Observatory has announced the winners of the Astronomy Photographer of the Year 2022.

More than 3,000 submissions from 67 countries were reviewed. The big winner was Gerald Rehmann with his photograph of Comet Leonard, which was discovered in 2021. Now she is rapidly leaving our solar system and, according to scientists, will never return.

Standing behind the cash register during a robbery reduced the risk of injury for salespeople.

Psychologists from Canada and the United States studied videos of attacks on 760 US stores to understand how the behavior of the seller depends on the risk of injury during a robbery. It turned out that if at the beginning of the attack the victim is behind the cash register, then the risk of using weapons by the perpetrator is reduced. How the raid ends for the seller depends 6-11 percent on the place where the employee meets the beginning of the incident.

VR glasses helped to reduce the dose of anesthetic during surgery.

Immersion in VR allowed anesthesiologists to reduce the dose of propofol required for sedation during hand surgery. Also, patients who used VR glasses took less time in the postoperative department of the clinic compared to patients from the control group.

Satellite Internet from Starlink has become available on all continents of the Earth.

Starlink's broadband Internet service is now available on all continents of the Earth, said company founder Elon Musk. SpaceX has launched 54 more Starlink satellites into orbit, and now the size of the company's satellite constellation has exceeded 3 thousand.

The James Webb telescope is broken.

Problems began with the main device - the MIRI mid-infrared camera. The saddest thing is that the camera itself works without deviations, and the spectrograph began to act up. It was he who was the main element of the telescope and allowed to "sniff" other planets and galaxies, recognizing their chemical composition.
