In a NASA simulation of an asteroid impact, scientists concluded they couldn’t stop a space rock from decimating Europe

Posted by in categories: asteroid/comet impacts, existential risks

Scientists around the world have been bamboozled this week by a fictitious asteroid heading toward Earth.

A group of experts from US and European space agencies attended a week-long exercise led by NASA in which they faced a hypothetical scenario: An asteroid 35 million miles away was approaching the planet and could hit within six months.

These meteorites landed on Earth after a 22-million-year voyage

Posted by in category: space

For the first time, scientists have been able to precisely map the flight path of an asteroid that landed on Earth and trace it back to its point of origin. The boulder-size fragment’s journey to our planet began 22 million years ago, according to new research.

The asteroid, known as 2018 LA, appeared like a fireball in the skies over Botswana on June 2, 2018, before breaking apart and landing in the Central Kalahari Game Reserve.

Prior to breaking up in Earth’s atmosphere, scientists determined that the asteroid was about 5 feet (1.7 meters) in diameter, weighed 12566 pounds and had been traveling at 37282 miles per hour.

Solar Wind Traveling 1,118,468 mph Due to Hit Earth Sunday

Posted by in category: futurism

Just days after Earth was hit by a coronal mass ejection (CME), it appears another blast of solar wind is due to impact Earth on Sunday; it is currently traveling at a brisk 1118, 468 mph towards the planet.

A minor G1-class Geomagnetic Storm is possible late Saturday into much of Sunday as the solar wind interacts with the Earth’s magnetic field. While the National Weather Service’s Space Weather Prediction Center has not issued any advisory for this solar wind yet, a watch or warning could be posted tomorrow for this event.

Hydroxyl Molecule Signature Detected in an Exoplanet Atmosphere for the First Time

Posted by in categories: alien life, chemistry, sustainability

An international collaboration of astronomers led by a researcher from the Astrobiology Center and Queen’s University Belfast, and including researchers from Trinity, has detected a new chemical signature in the atmosphere of an extrasolar planet (a planet that orbits a star other than our Sun).

Crew-1 Mission | Return

Posted by in categories: robotics/AI, space travel

SpaceX and NASA are targeting Saturday, May 1 at 8:35 p.m. EDT, or 00:35 UTC on May 2, for Dragon to autonomously undock from the International Space Station (ISS) and splashdown off the coast of Florida on Sunday, May 2 at approximately 2:57 a.m. EDT, 6:57 UTC, completing its first six-month operational mission to the Station.

A series of departure burns will move Dragon away from the orbiting laboratory, followed by the vehicle jettisoning the trunk to reduce weight and mass to help save propellant for the deorbit burn. Once complete, Dragon will re-enter Earth’s atmosphere and deploy its two drogue and four main parachutes in preparation for a soft water landing.

Targeting tumors with nanoworms

Posted by in categories: bioengineering, biotech/medical, chemistry, nanotechnology, supercomputing

Getting closer.


Drugs and vaccines circulate through the vascular system reacting according to their chemical and structural nature. In some cases, they are intended to diffuse. In other cases, like cancer treatments, the intended target is highly localized. The effectiveness of a medicine —and how much is needed and the side effects it causes —are a function of how well it can reach its target.

“A lot of medicines involve intravenous injections of drug carriers,” said Ying Li, an assistant professor of mechanical engineering at the University of Connecticut. “We want them to be able to circulate and find the right place at the right time and to release the right amount of drugs to safely protect us. If you make mistakes, there can be terrible side effects.”

Harvard scientists create gene-editing tool that could rival CRISPR

Posted by in categories: bioengineering, biotech/medical, genetics

Harvard’s Wyss Institute has created a new gene-editing tool that enable scientist to perform millions of genetic experiments simultaneously.


Researchers from the Harvard’s Wyss Institute for Biologically Inspired Engineering have created a new gene-editing tool that can enable scientists to perform millions of genetic experiments simultaneously. They’re calling it the Retron Library Recombineering (RLR) technique, and it uses segments of bacterial DNA called retrons that can produce fragments of single-stranded DNA.

When it comes to gene editing, CRISPR-Cas9 is probably the most well-known technique these days. It’s been making waves in the science world in the past few years, giving researchers the tool they need to be able to easily alter DNA sequences. It’s more accurate than previously used techniques, and it has a wide variety of potential applications, including life-saving treatments for various illnesses.

The Army Wants to Give Its Robots Living Muscle Tissue

Posted by in categories: military, robotics/AI

It’s exactly as weird as it sounds.


The U.S. Army is looking into using animal muscle tissue as a means to move robots.

The Army Research Laboratory believes its bots could use real muscle, which allows most living things to move and manipulate their environments, instead of mechanical arms, wheels, tracks, and other systems to travel across the battlefield. The concept, which some might find disturbing, is an example of the new field of “biohybrids.”
