Self-healing textiles not only repair themselves, but can neutralize chemicals

Posted by in categories: biological, materials

UNIVERSITY PARK, Pa. — Someday, chemically protective suits made of fabric coated in self-healing, thin films may prevent farmers from exposure to organophosphate pesticides, soldiers from chemical or biological attacks in the field and factory workers from accidental releases of toxic materials, according to a team of researchers.

“Fashion designers use natural fibers made of proteins like wool or silk that are expensive and they are not self-healing,” said Melik C. Demire l, professor of engineering science and mechanics. “We were looking for a way to make fabrics self-healing using conventional textiles. So we came up with this coating technology.”

NASA’s Fermi mission expands its search for dark matter

Posted by in categories: cosmology, particle physics

Dark matter, the mysterious substance that constitutes most of the material universe, remains as elusive as ever. Although experiments on the ground and in space have yet to find a trace of dark matter, the results are helping scientists rule out some of the many theoretical possibilities. Three studies published earlier this year, using six or more years of data from NASA’s Fermi Gamma-ray Space Telescope, have broadened the mission’s dark matter hunt using some novel approaches.

“We’ve looked for the usual suspects in the usual places and found no solid signals, so we’ve started searching in some creative new ways,” said Julie McEnery, Fermi project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “With these results, Fermi has excluded more candidates, has shown that dark matter can contribute to only a small part of the gamma-ray background beyond our galaxy, the Milky Way, and has produced strong limits for dark matter particles in the second-largest galaxy orbiting it.”

Dark matter neither emits nor absorbs light, primarily interacts with the rest of the universe through gravity, yet accounts for about 80 percent of the matter in the universe. Astronomers see its effects throughout the cosmos—in the rotation of galaxies, in the distortion of light passing through galaxy clusters, and in simulations of the early universe, which require the presence of dark matter to form galaxies at all.

U.S. Air Force’s plan to improve radio communications? Plasma bomb the atmosphere

Posted by in categories: military, satellites


Radio communication is a weak point for most military operations — it is often not long enough or strong enough to adequately meet soldiers’ needs. The U.S. Air Force’s “go big or go home” solution to improve their long-distance calls? Supercharge the atmosphere by detonating aerial plasma bombs attached to tiny satellites, reports New Scientist.

The Air Force is asking for help in developing plasma bombs, which would be delivered to the atmosphere by tiny cube satellites and then detonated to release ions upon arrival. The Air Force is working with several research teams, each of which is tasked with coming up with their own design for the plasma bombs. The first stage of the project is theoretical, requiring researchers to come up with an atmospheric plasma delivery method. Selected researchers then will be invited to test their proposal in a vacuum chamber simulator and eventually on exploratory flights.

Commercial Space Travel And Colonization: SpaceX, NASA, And NextSTEP Make Preparations For Lift Off

Posted by in categories: business, Elon Musk, space travel, sustainability

Commercial space travel is about to become a reality brought about by many private companies bent on taking their earthbound successes into space. The FAA is now open to granting permits to private companies to travel into space. It is hoped that this activity will lead to the colonization of Mars.

Elon Musk of SpaceX has the goal of beginning the colonization of Mars in the next decade. He plans to make commercial space travel and colonization a reality in his lifetime, according to The Washington Post. Mr. Musk is the mastermind behind both Tesla and SpaceX. He is one of the most brilliant minds of our time. An innovator and businessman, Elon has a track record of making dreams a reality and turning his plans into tangible results. Comparing his project to the colonization of America, Mr. Musk explains why he thinks people will agree to move to mars.

Why haven’t we found any aliens yet?

Posted by in categories: alien life, evolution

Many years ago, Carl Sagan predicted there could be as many as 10,000 advanced extraterrestrial civilizations in our galaxy.

After nearly 60 years of searching without success, a growing list of scientists believe on Earth only came about because of a lucky series of evolutionary accidents, a long list of improbable events that just happened to come together at the right time and will never be repeated. Is it possible they are right and we are all there is? Highly unlikely.

Earth is a typical rocky planet, in an average solar system, nestled in the spiral arm of an ordinary galaxy. All the events and elements that came together to build our world could happen almost everywhere throughout the galaxy and there should be nothing unusual about the evolution of life on this planet or any others.

My dispatch for Vice from the recent successful RAAD Festival—a giant gathering of longevity enthusiasts:

In less than a month, I’ll mark the two-year anniversary to my presidential campaign for the Transhumanist Party. My run for the White House was never about winning, but spreading the idea that Americans can achieve indefinite lifespans through science and technology—if only the government were to help out and put significant resources into the anti-aging field.
