It's easy to learn chemistry. Mr. Science Teacher provides a simple solution for anyone wanting help in understanding chemistry.

Effingham, IL (PRWEB) February 02, 2013

Did high school chemistry ever seem like a foreign language? How can teachers expect students to comprehend the foundations of chemistry when many are stuck trying to just understand the language?

Forget the frustration, the countless hours of homework, and the lost efforts on exams. Relax. Were going to climb mountains. The goal is to attain success and this is the day to do it.

With about ten minutes of effort, anyone will be able to write and name the correct formula for thousands of chemical compounds without knowing any chemistry. The key to the language of chemistry is simply adding and subtracting numbers to get to zero. Mr. Science Teacher has made understanding Chemistry simple, by first downloading Mr. Science Teachers Periodical Table of Ions and then watch a short YouTube video. Its all free.

It's amazing at how easy naming chemical compounds is about to get. Download Mr. Science Teachers Periodic Table and watch the video today.

Mr. Science Teacher ® Announces "The Language of Chemistry"

AMSTERDAM, February 4, 2013 /PRNewswire/ --

Comprehensive, referenced and well-structured data allows users to increase speed and accuracy of decision making in the drug development process

Elsevier, a world-leading provider of scientific, technical and medical information products and services, today announced the launch of Reaxys Medicinal Chemistry. It offers medicinal chemists access to comprehensive, referenced and well-structured data to enhance the compound selection process across discovery and pre-clinical stages in drug research and development. Reaxys Medicinal Chemistry will significantly improve the efficiency and productivity of researchers engaged in the process of designing compounds and optimizing their compatibility with one or more targets in order to successfully treat a disease.

Dr. Juergen Swienty-Busch, Product Lead for the Reaxys suite at Elsevier, said, "The greatest challenge of medicinal chemistry is to reduce the number of drug candidates that fail in late stages, significantly increasing the cost of bringing a drug to market. The well-known mantra 'fail early, fail cheap' is now central to the drug discovery process, with much of the responsibility borne by medicinal chemists."

Medicinal chemists develop strategies to find new drugs and to improve not only the efficacy of compounds but also selectivity, ADME properties and safety end-points. To support these strategies, medicinal chemists need to have access to up-to-date, well organized and high-quality experimental data on druggable targets, pharmacological effects, biological data points, and ADME properties associated with chemical compounds.

Reaxys Medicinal Chemistry sources its data from a vast repository of peer-reviewed journal articles, patents and regulatory information, encompassing millions of compounds and associated biological data linked to thousands of druggable proteins. It brings this information together into a single, easily searchable solution that gives pharmaceutical companies access to comparative data.

Reaxys Medicinal Chemistry can be used in conjunction with Elsevier's suite of life science products; including Reaxys, the leading chemistry discovery engine, and PharmaPendium, which focuses on regulatory approvals and drug safety. This solution effectively brings together lead identification, confirmation and drug repurposing.

February 4, 2013

Cambridge, MA: On Monday, February 4, 2013, JoVE (Journal of Visualized Experiments) will launch the first scholarly scientific video publication for chemistry. Following its successful introduction of video publications for the biological and physical sciences, JoVE received numerous requests for a chemistry counterpart. In response, the journal is launching a new section, JoVE Chemistry, dedicated to visualized publication of experiments across different areas of chemistry research including organic chemistry, chemical biology, electrochemistry, and polymer chemistry, among others.

"Similar to research in biology and physics, experimental research in chemistry suffers from a lack of reproducibility that can be solved by visualized publication. Therefore, it is natural to expand JoVE's novel publication approach to chemistry as well", says Moshe Pritsker, the CEO and co-founder of JoVE.

The debut article in JoVE Chemistry features a novel experimental approach to investigate antifreeze proteins using a device known as the nanoliter osmometer. This video article was filmed at the laboratory of Dr. Ido Braslavsky at the Hebrew University of Jerusalem in Israel. Explaining the function of antifreeze proteins, Dr. Braslavsky says: "When an antifreeze protein binds to an ice crystal, the protein inhibits growth of ice and lowers the melting point. This creates a difference between the melting and freezing point of ice known as thermal hysteresis."

By studying the properties of ice-binding proteins and thermal hysteresis, scientists gain insight into how arctic organisms can survive freezing temperatures without cellular destruction. Ice binding proteins are already used in hypothermia therapy, cryosurgery, the making of low-fat ice cream, and the lengthening of shelf life in frozen foods.

Dr. Braslavsky tells us, "I am studying the potential for antifreeze proteins to be used in cryopreservation. If we can learn from nature how to freeze or survive freezing better, we can use these strategies to extend our own lives." He also explains that, "chemistry is highly visual, and contains a lot of microscopy and reactions that change color when complete. By putting these aspects of chemistry in the forefront of publication and demonstrating the experimental steps, JoVE will become invaluable to chemists and make hard-to-learn techniques reproducible."

"JoVE pays tribute to the central science with the opening of the newest section, JoVE Chemistry," says Alexa Meehan, the JoVE's Deputy Editorial Director. "This highly anticipated addition will facilitate the experimental research in one of the purest sciences and will further a transition of JoVE from a biological journal into a platform video journal for all scientific disciplines."

JoVE expands scientific video publication into chemistry

Modern computer games consoles have controllers that vibrate – when you crash your car in a racing game or get shot in a shoot-em-up, you get a jolt through your fingers, which is designed to increase the realism of the game and enhance your experience.

Imagine if you could do the same thing with chemistry. You sketch out some molecules, then move them together to see if (or how) they will react. As virtual electron clouds approach each other, they push back, resisting your efforts to push them any closer. You try different angles until you find the right geometry, or push hard enough to force them to react with each other.

All the while, in the background, the computer is making quantum chemical calculations in real time. This is Markus Reiher’s vision of the future. Together with his team at the Swiss Federal Institute of Technology (ETH) in Zurich, he is developing ‘haptic quantum chemistry’ systems. This involves both working out ways to speed up quantum chemical calculations to the point where they can be done in real time, but also developing ways of translating those calculations into a physical feedback system that exploits our incredibly sensitive sense of touch.

At the moment, the system is controlled by a pen-like device, but Reiher has visions of taking it into three dimensions using hardware developed for virtual reality simulations.

Such physical feedback would be a much more intuitive way for chemists to learn and explore reaction mechanisms and map out potential energy surfaces. Trying to work out whether your latest synthesis plan is reasonable? Give it a go in the virtual world first. Stuck on a reaction mechanism homework problem? Feel your way to the answer.

Of course, there are computational, theoretical and technological hurdles to get over, but the chemists have an advantage – they can feed off the resource-hungry world of video games to provide the hardware and computational power. Using chips developed to handle the graphics engines of realistic games means that massive numbers of calculations can be done in parallel.

When my tutors said that synthetic chemistry is something you ‘just get a feel for’, I don’t think this is quite what they had in mind, but I’m definitely looking forward to the day when I can.
