Don’t Miss This Newly Discovered, Bright Green Comet Streaking Past Earth This Week

Posted by in category: space

Earth is getting a special celestial visitor this week in the shape of comet C/2018 Y1 Iwamoto — this sparkling, green-hued hunk of ice and minerals is already visible in the night sky through telescopes and even binoculars.

It’s the first binocular comet of 2019 – which means a comet that’s visible from Earth through binoculars, as you might have guessed from the name; we only get a few of them each year.

This particular comet was only discovered a couple of months ago – credit due to amateur astronomer Masayuki Iwamoto – and the icy rock is calculated to take 1,371 years to orbit the Sun on a stretched out, elliptical path.

3D Printed Dress from Iris van Herpen Pushes Boundaries of Fashion

Posted by in categories: 3D printing, education

Too many people believe that art and science exist as polar opposites and have delineated the disciplines as existing in an irreconcilable dichotomy that acts to drive the two types of knowledge apart. This conceptualization of the knowledge cultures is akin to placing two magnets next to each other such that their same poles when aligned repel each other: it foolishly denies the absolute attraction that exists when you simply flip one magnet the other way. Centuries ago, this attraction between art and science was understood as a given. The most easily identifiable product of this was a person such as Leonard da Vinci, whose work didn’t move back and forth between science and art, but rather understood the two as inextricably interwoven.

In the world of 3D printing, there appears to be developing an understanding that the bubbles of art and science are actually simply contorted ways of viewing a larger field of human knowledge. Dutch designer Iris van Herpen likes to play in the field and apply her understanding to the creation of fashion collections. Her pieces are explorations that encourage collaborative efforts because of the breadth of expertise in a wide variety of fields needed to create the pieces she has in mind. For a 2013 collection, she worked with photographer Nick Knight, who had captured images of the way water moved when splashed upon the nude body, in order to turn those images into garments. It became clear to Knight that van Herpen understood the inseparable nature of art and science, as he explained in an interview with the New York Times:

New molecules reverse memory loss linked to depression, aging

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

These molecules not only rapidly improve symptoms, but remarkably, also appear to renew the underlying brain impairments causing memory loss in preclinical models.

“Currently there are no medications to treat cognitive symptoms such as memory loss that occur in depression, other mental illnesses and aging,” says Dr. Etienne Sibille, Deputy Director of the Campbell Family Mental Health Research Institute at CAMH and lead scientist on the study.

What’s unique and promising about these findings, in the face of many failures in drug development for mental illness, is that the compounds are highly targeted to activate the impaired brain receptors that are causing memory loss, he says.

The Green New Deal could help farmers help the planet

Posted by in category: climatology

This month, a group of Democratic lawmakers called for an ambitious plan for the United States to reach net-zero carbon pollution in 10 years. While experts debate whether the proposal is technologically or politically feasible, the so-called Green New Deal is about more than shifting to cleaner, more advanced forms of energy sources. It’s also about shifting to more traditional forms of agriculture.

While farming generally takes a back seat to energy in discussions of climate, it accounts for up to a third of carbon pollution, by one account. Tractors and trucks that harvest and transport our food burn gasoline and diesel, generating pollution. Synthetic fertilizers derived from fossil fuels spur the release of heat-trapping gas from the soil, and cows and sheep emit large volumes of planet-warming pollution. Then there is the matter of agricultural giants burning forests to clear land for farming and grazing, thereby releasing carbon stored in trees into the atmosphere and reducing the capacity of the land to store CO2.

And yet, while agriculture is a big part of the problem, it can also be part of the solution. Smart growing practices can help soak up pollution and store it in the ground — what’s known as carbon farming.

Monkeys With Superpower Eyes Could Help Cure Color Blindness

New Map of Dark Matter Spanning 10 Million Galaxies Hints at a Flaw in Our Physics

Posted by in categories: cosmology, physics

An invisible force is having an effect on our Universe. We can’t see it, and we can’t detect it — but we can observe how it interacts gravitationally with the things we can see and detect, such as light.

Now an international team of astronomers has used one of the world’s most powerful telescopes to analyse that effect across 10 million galaxies in the context of Einstein’s general relativity. The result? The most comprehensive map of dark matter across the history of the Universe to date.

It has yet to complete peer-review, but the map has suggested something unexpected — that dark matter structures might be evolving more slowly than previously predicted.

Soon you may be able to 3D print clothing in your own home

Posted by in categories: 3D printing, habitats

In contrast, 3D-printed clothes can simply be dumped into blenderlike machines that turn the plastics into powder that can then be used to print out something new. And since 3D printing easily allows for custom sizing, the process is inherently frugal with materials.

But there are plenty of challenges that must be overcome before 3D-printed apparel goes mainstream.

One is cost. Even the smallest home 3D printers run several hundred dollars. A printer capable of printing human-sized apparel is beyond the reach of individual consumers. And it takes far longer to print an article of clothing than to produce a similar article via weaving or knitting. Peleg’s jacket, for example, takes about 100 hours to print.
