In virtual reality, you can now touch anything and feel it in reality.

The HaptX G1 contains 2 gloves (450 grams each) and a backpack (8 kg). Gloves simulate touching objects in virtual reality. Gloves are pressed against the part of the hand that touches something in the VR environment. This happens with the help of compressed air, which is supplied from a backpack. The cost of the device is $4.500

The world may be left without beer.

Production under threat due to climate change. The main ingredients for beer, such as hops and barley, do not tolerate heat very well. For example, barley production in Europe fell by 12% between 1964 and 2015 due to the weather. If the climate crisis worsens, the necessary ingredients for brewing beer will not be available.

Yusuke Narita's radical decision

Japanese professor Yusuke Narita proposed to solve the problem of aging in the Land of the Rising Sun in a radical way - by mass suicide of the elderly. He believes that gerontocracy is holding back progress in the country - there are a lot of elderly people in the country, they pull the budget on themselves and do not allow young people to break through. In general, the professor himself said that this is a metaphor, but young Japanese do not think so - he already has thousands of followers.

Black holes could be alien computers.

Black holes could be alien computers. Such a funny theory was put forward in a very authoritative German Max Planck Institute. According to scientists, the physics and behavior of black holes make them ideal quantum computers with endless possibilities. And it is possible that advanced aliens have learned to use them.

Xiaomi is on guard for your laziness.

The company has released a "smart" toilet for cats, which can be left uncleaned for 14 days. The gadget automatically removes all unnecessary in a special container, and then eliminates odors. The second feature is the connection to a smartphone: the device will tell you if something is wrong with the health of the pet.

Spices from all over the world were found on a ship that sank centuries ago.

Maritime archaeologists have stumbled upon a 15th-century ship that belonged to the King of Denmark. There they found a huge collection of spices: dill, ginger, saffron, cloves and about 3,000 more samples. The spices have spent 527 years under water and have retained their full flavor.

Elon Musk has named his Shiba Inu dog, Floki, CEO of Twitter.

He noted that the dog is perfect for this position: “He is good at numbers, he has excellent style.”

In Hawaii, the Kilauea volcano has woken up again.

Lava floods the roads, the eruption has already triggered an earthquake of 4.8 points and the locals are not in the mood for jokes.

Scientists have tested the male contraceptive "on demand" - one hundred percent effective.

They found a compound that blocks sAC activity in sperm. Tests on male laboratory mice showed that after taking the drug with TDI-11861, no more than 6% of spermatozoa remained mobile in one individual. But the effect turned out to be short-lived and completely reversible - the contraceptive effect disappeared in a day. During the second experiment, males who took the drug mated with females. None of the 52 attempts to conceive offspring were unsuccessful. Side effects scientists have not yet found.

Leonardo da Vinci calculated the gravitational constant almost exactly long before Newton.

Modern physicists have discovered a series of sketches in da Vinci's diaries with triangles and sand-like particles pouring out of a jar. They translated notes written in the famous left-handed mirror script, which reads from right to left. It turned out that da Vinci described experiments with the fall of various objects. He already then suggested that water or sand would not fall at a constant speed, but would rather accelerate due to gravity - this idea was far ahead of its time.

Biologists have proposed kangaroos to "help" cows cope with their contribution to global warming.

They found that the feces of baby kangaroos could be useful in combating global warming: the bacteria contained in them reduced the production of methane in an artificial cow's stomach, which could potentially work on live cows. If successful, farmers will receive an inexpensive feed supplement that will reduce their farms' methane emissions. Sheep, cows and goats release huge amounts of dangerous greenhouse gas during digestion. It is about 30 times better than carbon dioxide at retaining heat in the atmosphere.

The meteorite Sar2667 entered the Earth's atmosphere in northern France.

This is the seventh case in history when the fall of a meteorite was predicted, and the calculated consequences were confirmed - Sar2667 did not cause any damage by disappearing into the dense layers of the atmosphere. It's nice that such incidents have learned to predict.

The Spanish police will inform the women about the past of their boyfriends.

The police decided to tell women if their partners were involved in cases of domestic violence in the past five years. Access to information will not be automatic - officers will have to assess the vulnerability of potential victims and the likelihood of being at risk of abuse after a complaint. An exception will be made only for women whose data is in the VioGen database of victims of gender-based violence - they will find out about their boyfriend's past right away.

Biologists have disproved the myth about the ability of trees to communicate through a mushroom network.

Canadian biologists conducted a meta-analysis of 26 studies and concluded that trees are not able to transmit signals to each other through an underground mushroom network. So they refuted the popular point of view of their colleagues. Also doubtful was the assumption that mature trees transfer nutrients to seedlings through an underground fungal network. Such streams do exist. But there is no evidence that they are impossible without mycorrhiza. That is, fungi do not affect plant growth. In addition, no work has supported the idea that trees send insect damage signals through the fungal network.

Women recognize unmarried men by smell.

Australian scientists conducted an experiment in which they asked 82 heterosexual women aged 18 to 35 to rate male body odors. It turned out that the aroma of unmarried men attracts them more. The researchers found that the body odor of a single man seemed more pleasant to most women. In addition, the more attractive the men's fragrance was, the higher the participants in the experiment rated their appearance. Perhaps the difference in smell is due to the fact that married men have better health and hygiene than single men, as well as testosterone levels and dietary habits.

Air pollution can cause depression.

American scientists have found a link between long-term exposure to air pollution and an increased risk of depression in old age. It has been found that an increase in average long-term exposure to fine particulate nitrogen dioxide in humans is associated with an increased risk of developing depression. However, the effect varied depending on comorbidities and other factors.

Scientists are close to creating a super-powerful quantum computer.

A team from the University of Sussex has developed a system capable of transferring information from one chip to another with 99.999993% reliability at record speeds. This, the researchers say, shows that the chips can be connected together to create a more powerful quantum computer. Potentially, this technology can be used in any area, including the creation of drugs through accurate simulation of chemical reactions, weather forecasting or analysis of the possible effects of climate change.

Chinese Chery is developing an ejection seat for cars.

In the event of an inevitable accident, the seats will shoot out of the car, saving the driver and passengers from injury. The development company has not yet told how the roof of the car will open and how the seats will land.

A drone that can fly and swim underwater.

The TJ-FlyingFish consists of a central domed hull and four struts, each equipped with a propulsion unit at the end. When the aircraft is in flight, all four struts point upward and the propellers rotate at the higher of the two speeds. After landing on the water, the poles turn down and rotate at a slower speed, guiding the drone underwater. After the drone finishes its stay under water, it can return to the surface and fly away. The TJ-FlyingFish weighs 1.63 kg and can soar for 6 minutes on a single battery charge or move underwater for 40 minutes. It is also capable of descending to a maximum depth of 3 m, and its maximum underwater speed is 2 m/s. The drone is completely autonomous and does not need an operator.

ChatGPT passed the USMLE exam for a US medical license.

It is noteworthy that the exam includes non-obvious questions that are almost impossible to google - you need to apply logic to answer. Over three attempts to pass the exam, ChatGPT scored between 52.4% and 75.0% of the scores. Passing score - 60%. It's funny that the PubMedGPT AI, trained exclusively on medical literature, was able to pass the exam by only 50.8%.
