Why Do Seahorses Have Square Tails?      

Scientists use a 3D printer and a hammer to find out

by Mary Beth Griggs

We’ve got a lot to learn from a seahorse’s tail. Unlike other animals, these fishes’ tails are square, not round–a fundamental difference in shape that scientists believe could lead to new developments in medicine, robotics, and even defense.

In a paper published today in Science, researchers found that the difference in shape actually made a huge difference in how resilient the seahorse’s tail is.

In order to figure out why the seahorse tail is square while so many other animal’s tails are round (rats, lizards, monkeys, cats, etc.), scientists printed out 3D replicas of the square tails and similarly sized round tails.

Then they smashed them with a hammer…

Man Finds Rare Nintendo PlayStation Console From Early '90s
In 1988, Sony and Nintendo worked together on a CD-ROM peripheral for the SNES. In 1991 it was revealed at the Consumer Electronics Show by Sony but the day after Nintendo announced that, actually, it was partnering with Phillips for its CD tech. Sony, furious, more or less spite-developed its half of the tech into the PlayStation 1 we know today, to get back at Nintendo. Because it was never actually released the Sony/Nintendo PlayStation is quite rare. So this one is quite a big deal.

A Satellite’s First Look at Earth Has a Stunning Photo of the Sahara

By Katharine Trendacosta

Sentinel-2A conducted its first ever scan of Earth on June 27th. The result was this gorgeous image of the Sahara in central Algeria, showing a glorious terrain of rocks and sand.

Sentinel-2 is the second of six planned Sentinel missions. A pair of satellites with multispectral high-resolution imaging systems, Sentinel 2 will be used to track land use, vegetation stress, soil and water cover, or satellite imagery for emergency response. This Sahara photo is only one of the first photos picked up by the satellite, the rest being shots of Europe.

The Yeezy Boost 750 Headphones

Kegan McDaniel, co-founder of KERO products, has re-imagined the boosts as headphones utilizing the different features from the sneaker. Overall taking in a grey color-way with the ear pads of course reminiscing of the Yeezy Boost sole, the cord takes from the rope lacing and finally the Adidas and YZY branding. Would you guys like rocking these with your boosts?

Hey I have a computer that is touch screen(I can't remember the exact model but it's the windows one that does a 360 and all that jazz) and I was wondering if u knew an app that lets me write in my stylus and converts to written font ?? I saw it once but haven't Been able to find it since. Thanks

Hi. Try using Windows Journal. Here’s a quick guide (excuse my handwriting):

On the Pen toolbar, tap Selection Tool‌ and draw a loop around the text that you want to convert. The page will look like this:

Tap the Actions menu, and then tap Convert Handwriting to Text.

A pop up will open with options about the conversion, including line breaks, and allowing you to edit a word if it converts it incorrectly.

Solar Energy Conversion Under Dark Conditions

By Amanda Staller

A research team from the University of Texas at Arlington comprised of both present and past ECS members has developed a new energy cell for large-scale solar energy storage even when it’s dark.

Solar energy systems that are currently in the market and limited in efficiency levels on cloudy days, and are typically unable to convert energy when the sun goes down.

The team, including ECS student member Chiajen Hsu and two former ECS members, has developed an all-vanadium photoelectrochemical flow cell that allows for energy storage during the night.

“This research has a chance to rewrite how we store and use solar power,” said Fuqiang Liu, past member of ECS and assistant professor in the Materials Science and Engineering Department who led the research team. “As renewable energy becomes more prevalent, the ability to store solar energy and use it as a renewable alternative provides a sustainable solution to the problem of energy shortage. It also can effectively harness the inexhaustible energy from the sun.”

Tangible Holographic Plasma

Fairy Lights in Femtoseconds: Aerial and Volumetric Graphics Rendered by Focused Femtosecond Laser Combined with Computational Holographic Fields

We present a method of rendering aerial and volumetric graphics using femtosecond lasers. A high-intensity laser excites a physical
matter to emit light at an arbitrary 3D position. Popular applications can then be explored especially since plasma induced by a femtosecond laser is safer than that generated by a nanosecond laser. There are two methods of rendering graphics with a femtosecond laser in air: Producing holograms using spatial light modulation technology, and scanning of a laser beam by a galvano mirror. The holograms and workspace of the system proposed here occupy a volume of up to 1 cm^3; however, this size is scalable depending on the optical devices and their setup. This paper provides details of the principles, system setup, and experimental evaluation, and discussions on scalability, design space, and applications of this system. We tested two laser sources: an adjustable (30-100 fs) laser which projects up to 1,000 pulses per second at energy up to 7 mJ per pulse, and a 269-fs laser which projects up to 200,000 pulses per second at an energy up to 50 ¹J per pulse. We confirmed that the spatiotemporal resolution of volumetric displays, implemented with these laser sources, is 4,000 and 200,000 dots per second. Although we focus on laser-induced plasma in air, the discussion presented here is also applicable to other rendering principles such as fluorescence and microbubble in solid/liquid materials.
