Bill Gates isn’t going to use it to track you.

Your next doctor’s appointment could soon become much more informative thanks to new microchips the size of dust mites, only visible beneath a microscope.

Picture this: Your surgeon wants to continuously monitor your lungs prior to a procedure to ensure your respiratory system is strong enough to deal with anesthesia. So, a technician uses a hypodermic needle to inject a few small microchips into your body. Then, they use an ultrasound machine to communicate with the chips, which show your lungs are primed for the operation. Your subsequent surgery is a breeze.

The US Defense Advanced Research Projects Agency (DARPA) has recently commissioned three private companies, Blue Origin, Lockheed Martin and General Atomics, to develop nuclear fission thermal rockets for use in lunar orbit.

Such a development, if flown, could usher in a new era of spaceflight. That said, it is only one of several exciting avenues in rocket propulsion. Here are some others.

The standard means of propulsion for spacecraft uses chemical rockets. There are two main types: solid-fueled (such as the solid rocket boosters on the Space Shuttle), and liquid-fueled (such as the Saturn V).

In a decade-long quest, scientists at Berkeley Lab, the University of Hawaii, and Florida International University uncover new clues to the origins of the universe – and land new chemistry for cleaner combustion engines.

For nearly half a century, astrophysicists and organic chemists have been on the hunt for the origins of C6H6, the benzene ring – an elegant, hexagonal molecule comprised of 6 carbon and 6 hydrogen atoms.

Astrophysicists say that the benzene ring could be the fundamental building block of polycyclic aromatic hydrocarbons or PAHs, the most basic materials formed from the explosion of dying, carbon-rich stars. That swirling mass of matter would eventually give shape to the earliest forms of carbon – precursors to molecules some scientists say are connected to the synthesis of the earliest forms of life on Earth.

On June 11, 2021 CNSA published new Hi-Res Mars images Zhurong Rover (Chinese Tianwen-1 mission) with amazing details of Utopia Planitia on Red Planet. Rover dropped/deployed special instrument camera to make group images. Camera made first shot capturing Mars Lander and Zhurong Rover together in single frame. Resolution of the images is incredible. Chinese Zhurong Mars Rover has been working on the surface of Mars for 26 Martian days, carrying out environmental perception, fire surface movement, and scientific exploration. Zhurong also made first panoramic 360 degrees image at Utopia Planitia on Mars. There is image of Parachute pack and Heat Shield on the surface of Red Planet.

A secure quantum internet is one step closer thanks to a quantum memory made from a crystal, which could form a crucial part of a device able to transmit entangled photons over a distance of 5 kilometres. Crucially, it is entirely compatible with existing communication networks, making it suitable for real-world use.

There has long been a vision of a quantum version of the internet, which would allow quantum computers to communicate across long distances by exchanging particles of light called photons that have been linked together with quantum entanglement, allowing them to transmit quantum states.

The problem is that photons get lost when they are transmitted through long lengths of fibre-optic cable. For normal photons, this isn’t an issue, because networking equipment can simply measure and retransmit them after a certain distance, which is how normal fibre data connections work. But for entangled photons, any attempt to measure or amplify them changes their state.
