The People’s Republic of China, the French Republic, the Russian Federation, the United Kingdom of Great Britain and Northern Ireland, and the United States of America consider the avoidance of war between Nuclear-Weapon States and the reduction of strategic risks as our foremost responsibilities.

We affirm that a nuclear war cannot be won and must never be fought. As nuclear use would have far-reaching consequences, we also affirm that nuclear weapons—for as long as they continue to exist—should serve defensive purposes, deter aggression, and prevent war. We believe strongly that the further spread of such weapons must be prevented.

We reaffirm the importance of addressing nuclear threats and emphasize the importance of preserving and complying with our bilateral and multilateral non-proliferation, disarmament, and arms control agreements and commitments. We remain committed to our Nuclear Non-Proliferation Treaty (NPT) obligations, including our Article VI obligation “to pursue negotiations in good faith on effective measures relating to cessation of the nuclear arms race at an early date and to nuclear disarmament, and on a treaty on general and complete disarmament under strict and effective international control.”

A large, rocky asteroid is going to fly by Earth next week.

At 1 kilometer (3,280 feet) long, it’s roughly two and a half times the height of the Empire State Building, and it’s been classed a “Potentially Hazardous Asteroid” due to its size and its regular close visits to our planet.

But don’t worry, this month’s visit is going to have a very safe clearance, with the asteroid zipping by at a distance of 1.93 million kilometers (~1.2 million miles) away from Earth – that’s roughly 5.15 times more distant than the Moon.

Five of the world’s largest nuclear powers pledged on Monday to work together toward “a world without nuclear weapons” in a rare statement of unity amid rising East-West tensions.

“A nuclear war cannot be won and must never be fought,” said the joint statement, which was issued simultaneously by the United States, Russia, China, the United Kingdom and France. “As nuclear use would have far-reaching consequences, we also affirm that nuclear weapons — for as long as they continue to exist — should serve defensive purposes, deter aggression, and prevent war.”

The statement also stressed the importance of preventing conflict between nuclear-weapon states from escalating, describing it as a “foremost responsibility.”

Using the world’s smallest computer, University of Michigan (UM) researchers were able to figure out why one species of snail was able to survive a situation that pushed more than 50 others into extinction.

“We were able to get data that nobody had been able to obtain,” researcher David Blaauw said in a press release. “And that’s because we had a tiny computing system that was small enough to stick on a snail.”

Unintended consequences: In 1974, scientists introduced the rosy wolf snail to the Society Islands, home to Tahiti, in the hopes it would help control the population of giant African land snails, which had become a major pest.

An asteroid as large as Big Ben will be approaching Earth in January, 2022. However, it is not the only asteroid heading towards Earth.


The year 2022 has just started and here we are with dire NASA warnings of potentially hazardous asteroids heading for Earth. The National Aeronautics and Space Administration (NASA) has reported that as many as five asteroids are coming towards the Earth in the first month of the year. An asteroid around the size if a bus will approach the Earth in the first week of January itself.

Asteroids, comets, and meteoroids are large rocks in space that orbit the Sun and occasionally vary their orbits due to the gravitational attraction of planets. When these space rocks do collide with any planet, it’s usually a disaster. That’s why, even when an asteroid with a diameter of more than 150 metres approaches Earth, NASA classifies it as a potentially hazardous asteroid and monitors it closely.

Asteroid 2021 YK which is 38 feet (12m) wide is expected to pass within 118,000 miles of Earth by today.

We thought that all the dinosaurs went extinct when an asteroid hit the earth some 65 million years ago until recently. Now we know that some of the dinosaur species, mostly avians, survived and become birds. Scientists are trying to tweak chicken DNA to produce atavistic, dinosaur-like, traits that are embedded in the genes of birds for years.

A research team led by Yale paleontologist and developmental biologist Bhart-Anjan S. Bhullar and Harvard developmental biologist Arhat Abzhanov conducted the first successful reversion of a bird’s skull features back in 2015. The team replicated ancestral molecular development to transform chicken embryos in a laboratory to turn its beak into a snout and palate configuration similar to that of small dinosaurs such as Velociraptor and Archaeopteryx.

“I wanted to know what the beak was skeletally, functionally and when this major transformation occurred from a normal vertebrate snout to the very unique structures used in birds,” Bhullar said.

We live in a very fast-changing world and quite an unpredictable one. In part, it is because we got lots of technological powers while our brain stays just the same as in pre-technological times. What do we teach children in this world? How can we help them to reflect on their thinking, get wiser in using the new technological powers, develop growth mindset and resilience, see the big picture and the interconnections within the complex systems (be that our body, ecological system, or the whole Universe)? We are trying to address these issues by teaching space science, AI and cognitive science, and existential risks and opportunities to pre-teens. In three years, the kids get an opportunity to talk to some of the most prominent thinkers in the field, reflect on deep questions, develop connections with specialists from multiple fields, from space law to ecology to virology, present their work at conferences.

But strangely, this green shade disappears before it reaches the one or two tails trailing behind the comet.

Astronomers, scientists, and chemists have been puzzled by this mystery for almost 90 years. In 1930, it was suggested that this phenomenon was due to sunlight destroying diatomic carbon. The carbon is created from the interaction between sunlight and organic matter on the comet’s head. However, due to the instability of dicarbon, this theory has been hard to test.

Scientists at UNSW Sydney have finally found a way to test this chemical reaction in a laboratory – and in doing so, has proven this 90-year-old theory correct. They solved this mystery with the help of a vacuum chamber, a lot of lasers, and one powerful cosmic reaction.
