You are on the Pro Robot channel and today we are going to talk about the soldiers of the future. Exoskeletons, ballistic helmets, military suits, chips and more are already being introduced into the armaments of different countries. In this issue we will find out what the super-soldier of the future will be like and what developments are being conducted in the military industry. Watch the video to the end and write your opinion in the comments: will robots replace humans in military service?

A giant star called VVV-WIT-08 exhibited a smooth, eclipse-like drop in brightness to a depth of 97% in 2012; minimum brightness occurred in April 2012 and the total event duration was a few hundred days, according to an analysis of data from the VISTA Variables in the Via Lactea survey (VVV), a project using the British-built VISTA telescope in Chile and operated by ESO.

It may belong to a new class of ‘blinking’ binary system, where a giant star — 100 times larger than the Sun — is eclipsed once every few decades by an as-yet unseen orbital companion.

The four spacecraft went up aboard a Long March 2D rocket on Thursday (June 10).

China launched four new satellites into orbit on Thursday (June 10), including a commercial satellite for tracking near-Earth asteroids.

Artemis 1: NASA SLS megarocket hits another milestone.

NASA’s SLS rocket that will carry Orion to the Moon for the Artemis I mission is shaping up. With the core stage in place, here’s a look at NASA’s megarocket.

When exposed to human-made noise, seagrass posidonia reveals permanent severe lesions in their sensory organs that sense gravity, which threatens their survival. This is the main conclusion of a recent study of the Laboratory of Applied Bioacoustics (LAB) of Universitat Politècnica de Catalunya BarcelonaTech (UPC) titled “Seagrass Posidonia is impaired by human-generated noise,” which is published in Nature Communications Biology.

These new findings demonstrate that plants have the physiological ability to perceive sounds, and just as importantly, reveal that commonly encountered sources of noise in the ocean can contribute to deplete their populations.

The last 100 years have seen the introduction of many sources of artificial noise in the sea environment, which have shown to negatively affect marine organisms. Many aspects of how noise and other forms of energy may critically impact the natural balance of the oceans are still unstudied. A lot of attention has been devoted to determining the sensitivity to noise of fish and marine mammals, especially cetaceans and pinnipeds, because they are known to possess hearing organs. Recent studies conducted at the Laboratory of Applied Bioacoustics (LAB) of the Universitat Politècnica de Catalunya, Barcelona Tech (UPC) have also shown that cephalopods, anemones and jellyfish, while lacking similar auditory receptors, are also affected by artificial sounds. Indeed, marine invertebrates have sensory organs whose main functions allow these species to maintain equilibrium and sense gravity in the water column.

The US Centers for Disease Control and Prevention now calls the Delta variant of the novel coronavirus, also known as B.1.617.2, a “variant of concern.”

The variant of concern designation is given to strains of the virus that scientists believe are more transmissible or can cause more severe disease. Vaccines, treatments and tests that detect the virus may also be less effective against a variant of concern. Previously, the CDC had considered the Delta variant to be a variant of interest.

Humans can do lots of things that plants can’t do. We can walk around, we can talk, we can hear and see and touch. But plants have one major advantage over humans: They can make energy directly from the sun.

That process of turning sunlight directly into usable energy —called photosynthesis —may soon be a feat humans are able to mimic to harness the sun’s energy for clean, storable, efficient fuel. If so, it could open a whole new frontier of clean energy. Enough energy hits the earth in the form of sunlight in one hour to meet all human civilization’s energy needs for an entire year.

Yulia Puskhar, a biophysicist and professor of physics in Purdue’s College of Science, may have a way to harness that energy by mimicking plants.

NASA finally approves the launch of an infrared asteroid hunting space telescope able to locate threats 30M miles away…

NASA has approved the Near-Earth Object Surveyor space telescope to help the space agency be better prepared for future asteroids that could pose a threat to Earth.

The 20-foot-long infrared telescope would help astronomers and planetary scientists find ‘most’ of the potentially hazardous asteroids and comets that come within 30 million miles of Earth’s orbit, also known as near-Earth objects (NEOs).
