A new kind of plastic that is able to maintain its original qualities when recycled

Posted by in category: materials

A team of researchers from the U.S., China, and Saudi Arabia has developed a new kind of plastic that is able to maintain its original qualities when recycled. In their paper published in the journal Science Advances, the group describes how the new plastic is made and how well it did when tested for recyclability.

For many years, plastics have been seen as a highly desirable modern advancement—they are light, strong, bendable when needed, and can be used in a very wide variety of applications. The down side to plastics, of course, is that they do not recycle very well and they take a very long time to decay. This has led to millions of tons of plastic waste winding up in landfills and in the water table. Because of that, scientists have been hard a work looking for a new kind of plastic that has all the advantages of the old plastic but also can be easily recycled. In this new effort, the researchers claim to have developed just such a plastic.

The researchers made the new plastic by preparing a bridged bicyclic thiolactone from a bio-based olefin carboxylic acid. The result was a plastic (they called PBTL) that had all the qualities of traditional plastics. They next tested their plastic by conducting bulk depolymerization at 100°C using a catalyst. Testing of the result showed the PBTL had been broken down into its original monomer. They followed that up by breaking down samples of PBTL (using a catalyst) at room temperature. And once again, close examination showed the sample had been broken down to the original monomer.

Genetic background may affect adaptions to aging

Posted by in categories: biotech/medical, chemistry, genetics, life extension, neuroscience

How we adapt to aging late in life may be genetically influenced, according to a study led by a psychologist at the University of California, Riverside.

The research, published in Aging Cell, has implications for how relate to aging. Epigenesis is a process in which chemicals attached to DNA control its activity. Epigenetic changes, which can be passed on to offspring, may be critical to accelerated aging as well as declines in cognitive and physical functioning that often accompany aging. Epigenetic modifications resulting in altered may occur due to a number of biological processes, including one the researchers focused on: DNA methylation.

In DNA methylation, groups are added to the DNA molecule. DNA has four different types of nucleotides: A, T, G, and C. DNA methylation occurs at the C bases of eukaryotic DNA. Changes in DNA methylation correlate strongly with aging.

The 15 Weirdest Galaxies in Our Universe

Posted by in category: cosmology

There are galaxies shaped like jellyfish, galaxies that consume other galaxies, and galaxies that seem to lack the dark matter that pervades the rest of the universe. Here are the strangest galaxies in the universe.

Tesla cars are going to play elevator music through external speaker because Elon Musk likes it

Posted by in categories: Elon Musk, media & arts, sustainability, transportation

Tesla vehicles are equipped with extrernal speakers.

The main function is to output a pedestrian warning sound, which has become required for electric vehicles in many markets due to the fact that they are quiet at low speeds.

Tesla CEO Elon Musk has been playing around with ideas on how to release other features that take advantage of the fact that the vehicles are now equipped with external speakers.

“The Inconstant Universe” –Weird Findings Point to a New Physics

Posted by in categories: cosmology, quantum physics

“Our standard model of cosmology is based on an isotropic universe, one that is the same, statistically, in all directions,” says astrophysicist John Webb at the University of New South Wales about the universal constant which appears inconstant at the outer fringes of the cosmos, it occurs in only one direction…” That standard model itself is built upon Einstein’s theory of gravity, which itself explicitly assumes constancy of the laws of Nature. If such fundamental principles turn out to be only good approximations, the doors are open to some very exciting, new ideas in physics.”

Those looking forward to a day when science’s Grand Unifying Theory of Everything could be worn on a t-shirt may have to wait a little longer as astrophysicists continue to find hints that one of the cosmological constants is not so constant after all.

Blue Origin team delivers lunar lander mockup to NASA

Posted by in categories: engineering, space travel

WASHINGTON — The Blue Origin-led team that is one of three working on lunar lander concepts for NASA’s Artemis program has delivered a full-sized mockup of that lander to the agency for testing by engineers and astronauts.

Blue Origin announced Aug. 20 that its “National Team” has installed an engineering model of the lander in the Space Vehicle Mockup Facility at the Johnson Space Center. The full-sized, but low-fidelity, mockup includes both the descent element, developed by Blue Origin, and ascent element, built by Lockheed Martin, and stands more than 12 meters high.

Oumuamua Could be Alien Probe as New Study Rules Out Alternative Explanation

Posted by in category: alien life

Oumuamua is an interstellar object that reached the solar system two years back. It showed unusual acceleration in its course across space, which led scientists to believe it could be a probe from another planet or even extraterrestrials. What it is.

Why it’s important

Oumuamua, from the very first day of its discovery, literally perplexed scientists, as it showed an unusual acceleration in its course across space. Now, in a new study report published in The Astrophysical Journal Letters, Loeb and Thiem Hoang, an astrophysicist at the Korea Astronomy and Space Science Institute, has claimed that the hydrogen hypothesis will not work in the real world, which means there could be still a scope that advanced aliens from deep space might have visited the solar system.

“Cold Tube” cooling system uses half the energy of an air conditioner

Posted by in categories: energy, sustainability

Air conditioners are a convenient way to cool down offices and homes, but they use huge amounts of energy in the process. A team of scientists has been developing an alternative solution for those warm summer months called the Cold Tube, which works by absorbing body heat emitted from a person and can use around half the energy of traditional systems as a result.

The notoriously bad energy efficiency of air conditioners has motivated the development a range of environmentally friendly solutions, from attachments that use water mist to pre-cool the units to solar-powered systems that produce hot water at the same time. In 2018, Richard Branson even launched a US$3 million competition aimed at developing more energy efficient air conditioners.

Similarly, the research team behind the Cold Tube has been investigating next-generation systems that keep people cool in more efficient ways. Made up of scientists from the University of British Columbia, Princeton University, the University of California, Berkeley and the Singapore-ETH Centre, the team took aim at the dehumidification process that is a critical function of today’s air conditioning systems.
