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…

Ladies of Litchfield: 1/?

The result of the last four days of my holidays from work. Quick 2-hour paintings of Daya, Red, Nicky, and Poussey (my fave). Will I do more? Probably. This show just has so many amazing characters - so much diversity.

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.”

Spark Your Brain


Adding exercise to your lifestyle sparks your brain function to improve learning on three levels:

First, it improves your mind’s alertness, attention,  mood, and motivation.

Second, it prepares and encourages nerve cells to bind to one another, which is the cellular basis for logging in new information.

Third, it spurs the development of new nerve cells from stem cells in the hippocampus.


Clementine: “Well, before we do the ultrasound, are there any new developments with the pregnancy?”

Umbra: “No. Just the same old complaint. The kid keeps hurting me…”

Clementine: “Well, you’re in your second trimester and the baby’s a vampire. As it grows, it’s taking twice as much plasma from you. We have to find an additional source. But first, let’s see how it’s doing. Maybe we’ll find out what you’re having too.”

New plan proposed to send humans to Mars

New Rochelle NY (SPX) Jul 01, 2015
A new, cost-constrained U.S. strategy to send humans on Mars, could be achieved within projected NASA budgets by minimizing new developments and relying mainly on already available or planned NASA assets. This approach is described in “A Minimal Architecture for Human Journeys to Mars,” published in New Space, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is

Day two of the week leading up to an all new Trauma: the midseason finale episode! We’re pleased to introduce one of our favorite members of the cast, Wilson Cruz as Dr. Colton Redken!

Meet Dr. Colton Redken, a flaming personality kindling within a middle-aged attending surgeon’s body. Rough around the edges and quick to lash out when threatened, he can be quick to judge his peers and hard of letting go of his initial assumptions. When you get to know him, however, he becomes much more complexly woven in his own intricate pattern of fear and pain. Get to know more about the man behind the hard exterior and learn to bend your views in light of new developments right along with Redken in the midseason finale of Trauma this Thursday at 12/11c!


The Challenger 2 is an advanced main battle tank built by BAE Systems Land Systems (formerly Vickers Defence Systems, then Alvis Vickers Ltd). Challenger 2 is in service with the British Army and with the Royal Army of Oman. The UK placed orders for 127 Challenger 2 tanks in 1991 and an additional 259 in 1994. In 1993 Oman ordered 18 Challenger 2 tanks and an order for a further 20 tanks was placed in November 1997.

Challenger 2 is equipped with an L30, 120mm rifled tank gun from BAE Systems Land Systems (formerly RO Defence). In January 2004, Land Systems was awarded a contract to develop a new smoothbore 120mm gun for the British Army Challenger tanks. Under the contract, a Challenger 2 has been armed with the Rheinmetall L55 smoothbore gun, as fitted on the Leopard 2A6 tank, and began firing trials in January 2006.

The L30 gun is made from electro-slag refined steel (ESR) and is insulated with a thermal sleeve. It is fitted with a muzzle reference system and fume extraction. The turret is capable of 360° rotation and the weapon elevation range is from -10° to +20°.

There is capacity for 50 120mm projectiles, including armour-piercing fin-stabilised discarding sabot (APFSDS), high-explosive squash head (HESH) or smoke rounds. The L30 gun can also fire the depleted uranium (DU) round with a stick charge propellant. With the DU round, the L30 is part of the Charm 3 gun, charge and projectile system.

The gun control is provided by an all-electric gun control and stabilisation system from BAE Systems. Challenger 2 is also equipped with a Boeing 7.62mm chain gun, which is located to the left of the main tank gun. The loader has a 7.62mm GPMG L37A2 anti-air machine gun, mounted on the cupola.

The turret is protected with second generation Chobham armour. A nuclear, biological and chemical (NBC) protection system is located in the turret bustle. On each side of the turret are five L8 smoke grenade dischargers, from Thales AFV Systems Ltd (formerly Helio Mirror Company).

Challenger 2 can also set a smoke screen by the injection of diesel fuel into the engine exhausts.
