Researchers in the biomedical sciences, such as bioelectrochemistry and biomedical engineering, work every day to create new processes and technology that will better the lives of all. The scientific community is recognizing one expert – Karl Diesseroth – for his two innovative techniques that are now widely used to study Alzheimer’s disease, autism, and other brain disorders.

Disseroth has just been awarded the Lurie Prize in Biomedical Sciences for his achievements in the advancement of brain research technology. Disseroth is the pioneer behind a process called CLARITY and the technique called optogenics. In case you missed them, here’s a brief recap:

What Is Penta-Graphene?

Researchers from Virginia Commonwealth University (VCU) in conjunction with universities in China and Japan have discovered a new structural variant of carbon that they are coining “penta-graphene.”

The new material is comprised of a very thin sheet of pure carbon that is especially unique due to its exclusively pentagonal pattern. Thus far, the penta-graphene appears to be dynamically, thermally and mechanically stable.

“The three last important forms of carbon that have been discovered were fullerene, the nanotube and graphene. Each one of them has unique structure. Penta-graphene will belong in that category,” said the paper’s senior author and distinguished professor in the Department of Physics at VCU, Puru Jena in a press release.

The inspiration for this new development came from the pattern of the tiles found paving the streets of Cairo. Professor at Peking University and adjunct professor at VCU, Qian Wang, got the inspiration that inevitably led to penta-graphene while dining in Beijing.

Sensors Make ‘Sixth Sense’ Possible

Scientists from Germany and Japan have developed a new magnetic sensor, which is thin, robust and pliable enough to be smoothly adapted to human skin, even to the most flexible part of the human palm.Image: IFW Dresden

Humans possess five basic senses: touch, sight, hearing, taste and smell. While we do not inherently possess any senses beyond those five, it is possible to tap into extended senses through science and technology.

Magnetoception, for example, is a sense which allows bacteria, insects and even vertebrates like birds and sharks to detect magnetic fields for orientation and navigation. While humans cannot organically perceive magnetic fields, scientist have just created a new sensor that may allow us to do so.

Researchers from Germany and Japan have developed a new magnetic sensor that is thin and pliable enough to be adapted to the human skin. This innovation makes equipping humans with magnetic senses a more viable reality.

This from Leibniz Institute for Solid State and Materials Research Dresden:

These novel magneto-electronics are less than two micrometers thick and weights only three gram per square meter; they can even float on a soap bubble. The new magnetic sensors withstand extreme bending with radii of less than three micrometer, and survive crumpling like a piece of paper without sacrificing the sensor performance. On elastic supports like a rubber band, they can be stretched to more than 270 percent and for over 1,000 cycles without fatigue. These versatile features are imparted to the magnetoelectronic elements by their ultra-thin and –flexible, yet robust polymeric support.

Solutions for the Climate Change Problem

“They will either remember us as the generation that destroyed its home, or the one that finally came to respect it.”

Check out this powerful short film about the need to solve the climate change problem.

Here at ECS, we aim to drive new ideas, experiments, research, and discovery in order to address some of the most pressing global issues. Check out the research our scientists are doing to find a solution to climate change and how our move toward Open Access could have serious implications for action on this topic.

Silicene Moves Us toward Super-Fast Computers

There’s an exciting new development in the world of single-atom thick materials, and surprisingly it doesn’t revolve around graphene.

Instead, scientist have shifted their attention to silicene: an exotic form of silicon that has fantastic electrical properties for computer chips.

Like graphene, silicene is a single-atom thick material that allows electrons to flow through it at amazingly high speeds. However, silicene does not occur naturally like graphene – it instead has to be grown in the lab on a sheet of silver.

Because of the difficulty encountered when attempting to produce silicene, its properties have only been theoretical until now. Recently, Deji Akinwande of the University of Texas at Austin turned his attention to this material and found a way to make a transistor out of silicene.

Electrochemistry Fights World Cancer

SA10519_WCD_Logo_4cCancer is among the leading causes of mortality worldwide. According to the World Health Organization, approximately 14 million new cases and 8.2 million cancer related deaths were recorded in 2012. If no major breakthroughs are made in the field, that number is expected to rise by 70 percent over the next two decades. In honor of World Cancer Day, we’re taking a look at a few ways electrochemical and solid state science aids in the fight against cancer.

Electrochemical Biosensing for Cancer Detection
By taking biopsy slices for colon cancer, researchers were able to use electrochemical biosensors to distinguish between cancerous and normal epithelial tissues. This development helped promote rapid cancer detection by eliminating pretreatment and providing results obtained within minutes of biopsy removal. Read the full paper here.

Polymer Based Sensors to Diagnose Breast Cancer
There are many issues that mammography faces, including the uncomfortableness of the screening and exposure to radiation. In order to solve this issues, electrochemical scientists developed an Electrical Impedance Tomography (EIT) system. This radiation-less technique aims to enhance early detection capabilities by generating a 3-D map of the breast. Read the full paper here.

The Science of Distilling

One brave man is distilling his own potent, yet drinkable, biofuel. Of course, there’s quite a bit of electrochemistry involved via this reflux still.

WARNING: Distilling alcohol is illegal in many places. (It can also be pretty dangerous for the novice distiller, so let’s leave this one to Hackett.)

Bill Nye + Deflategate = Climate Change?

Bill Nye the Science Guy drops some science on the Patriots and takes the opportunity to deliver a message on climate change.

Science can be a strange and wondrous world of extraordinary innovation and unbelievable discovery. Now, one of our favorite scientific innovations has made its return: the cyborg cockroach.

As you may remember, ECS Board Member and Senior VP Dan Scherson once co-authored a paper that detailed how a cyborg cockroach can generate and transmit signals wirelessly. (You can check paper out here – it’s open access!)

Now cyborg cockroaches are making their way back into science with a new study that uses the roaches to pick up sounds with small microphones and seek out the source of that sound.

The purpose of this development is to help emergency personnel find and rescue survivors in the aftermath of an accident.

The Real Science of an Alkali Metal Explosion

You may remember the classic alkali metal explosion demonstration in one of your early chemistry classes. Many educators use this experiment to show the volatile power of chemistry. The thought was that the unstable reaction was caused by the ignition of hydrogen gas, but scientists in the Czech Republic have found new information behind this classic demonstration by using high-speed video.

The researchers began investigating the science behind this experiment by dropping a sodium-potassium alloy droplet into water. From there, they recorded the explosion with a high-speed camera that is capable of capturing 10,000 frames per second.

Of course, there’s a video.
