The moment the comet disintegrated

The moment the comet disintegrated

Two photos taken with the Hubble space telescope last week show that comet C / 2019 Y4 broke into at least 55 pieces. C / 2019 Y4 was first detected in December 2019 by the ATLAS astronomical robot system of the University of Hawaii, USA. Astronomers have predicted it will increase its brightness and be visible to the naked eye in May 2020, becoming one of the most spectacular comets in the past two decades. However, C / 2019 Y4 suddenly dimmed since mid-March, causing many experts to speculate that the comet's core may have been fragmented or disintegrated. This hypothesis was confirmed on April 11 after amateur astronomer Jose de Queiroz first captured three comet fragments.

The most durable life jacket in the world, the fabric is 15 times stronger than steel

Dutch firm Vollebak has just launched a life jacket which is known as the most durable in the world with a dyneema outer surface - a fabric 15 times harder than steel. For years, this extreme sportswear brand has created the best and most durable outfits on the planet. With the product "Indestructible Puffer", the surface of the shirt cannot be waterproof or cut or torn.

Why are China and many countries racing to make artificial sun?

Why are China and many countries racing to make artificial sun?

In the search for clean energy, China and many countries are seeking fusion reactor solutions. Human energy needs never seem to have a limit. From fossil fuels, we begin to learn about nuclear energy, then the forms of renewable energy. However, any form of energy has its drawbacks. Fossil energy is cheap but polluting, high-cost and low-cost renewable energy, and nuclear energy has a radiation risk. Finding an infinite source of energy is the dream of man.

Without wipers, how will Tesla's Cybertruck clean up dust on the windshield?

Without wipers, how will Tesla's Cybertruck clean up dust on the windshield?

The Cybertruck monster car may have a lot of things that are superior to other conventional cars but it also lacks a lot of seemingly basic things. One of the shortcomings is that there is no wiper. It makes the front part of the car and front glass look like a complete plane, but this omission can be dangerous for drivers when dirt on the road can lose visibility. But with a new patent for using "Laser pulses to clean the dirt that sticks to glass on vehicles and mounts on solar panels", Tesla says it has a solution for cleaning dust. dirt on the windshield without the need for a traditional wiper.

US and France cooperate to track marine life from space

US and France cooperate to track marine life from space

According to New Atlas, NASA engineers in collaboration with French researchers at Center National d'Etudes Spatiales (CNES) started using space laser devices installed on CALIPSO and Cloud-Aerosol Lidar satellites. to track small marine creatures - krill, baby squid and small fish. CALIPSO lidar technology tracks the largest migration of organisms on the planet Researchers in the US and France used CALIPSO lidar in space to track the largest migration of organisms on the planet - (Photo: NASA).

Technology helps people see the world through animal eyes

Technology helps people see the world through animal eyes

Technology of analyzing quantitative color models helps scientists understand the behavior of animals and apply them to determine how to camouflage them. Researchers from the University of Queensland and Exeter have developed Quantitative Color Model Analysis (QCPA) technology that allows people to process and visualize environmental information in a similar way to animals. This technology enables humans to understand how animals perceive their surroundings through complex images and color patterns that control their behavior.

The first "built" residential 3D printer in the world

The first "built" residential 3D printer in the world

The non-profit organization New Story in collaboration with technology companies Icon and Echale is working to build the world's first residential area with 3D printing technology. This project was implemented in the Mexican state of Tabasco. As planned, 50 houses for the poorest in the village in this area will be built. Currently, 2 houses built with 3D printing technology have been completed.

The US military is dreaming of a device that helps soldiers see through walls

The US military is looking to help soldiers can "see through the wall" as in the film to quickly detect enemies in difficult missions. It is important to be able to quickly detect the location of an enemy's hideout to plan for raids and lightning attacks. Understanding that, the US Special Operations Command (SOCOM) wanted to create a detector capable of quickly detecting enemies' hiding places. According to the National Interest, the goal of this project is to create a handheld device that can detect objects behind an average sized space of about 15m2 and within a distance of nearly 2m.

Ribbed liquid metal helps the robot to heal itself

Ribbed liquid metal helps the robot to heal itself

In Japan, robotic researchers from Tokyo University's JSK Laboratory have created a prototype robotic leg with a metal ribbed that can repair fractures. How did it do this? Simply by melting itself and then changing itself into a single piece. The work was presented at the recent IEEE / RSJ 2019 International Conference on Smart Robots and Systems (IROS). Researchers who developed a special metal veins for robots from Japan said the module will automatically recover consists of two halves connected through magnets and springs.

The Li-S battery helps the smartphone to work all week without charging

The new battery could power smartphones for five days or allow electric cars to run 1,000km on a single charge. Associate Professor Matthew Hill, Dr. Mahdokht Shaibani and Professor Mainak Majumder (from left to right) are involved in the development of Li-S batteries at Monash University. (Photo: New Atlas). Researchers at Monash University in Melbourne develop "the world's most efficient" lithium-sulfur batteries, which are four times more efficient than conventional batteries. They are seeking to commercialize this technology and enhance its benefits in the fight against climate change. They published their research today in the journal Science Advances.
