 "Building on recent work programming computers to identify synthetic pathways leading to pharmaceutically complex molecules, researchers in Poland and South Korea have unveiled computerized methods to suggest only synthetic strategies that bypass patent-protected aspects of essential drugs.""When we started this project, I was somewhat skeptical that the machine would find any viable synthetic alternatives -- after all, these are blockbuster drugs worth gazillions of dollars, and I was sure that the respective companies had covered the patent space so densely that no loopholes remained," says senior author Bartosz Grzybowski, Developing the painstakingly increases purity and reduces the cost. The researchers decided to freeze each target molecule to allow the computer to approach on basis of mechanistic rule. In each run the program recommended the commercial synthesis. "By algorithmically locating the key bonds on which patents hinge and propagating them down Chematica's retrosynthetic trees, we can generate synthetic solutions from alternative yet economical starting materials, achieving a real practical impact," Grzybowski says. This is saying that Chematicas existing functions propose new plans that avoided those already patented. Chematicas patent dodging ability could help the chemists with new approach and avoid the patent law. These programs are trying to aid pharmaceutical companies help protect their property and help boost research and development of organic chemistry.

Lab 7

Lab 7 was the most difficult labs their was to code. This lab involved designing and coding. The main part of the lab was to link our web pages to one where you just click lab1-lab7 without having to go back and forth. We first did this by duplicating our folders of lab1-lab6 and copying them into lab 7. This was because we needed the files to be copied into the lab 7 directory to ensure the links wouldn't change when we create our web page. Once all files are in we have to create a index.html in lab 7 because this was the homepage and how the website would read it as index.html. After this part we had to go back into Photoshop to design our images to click for each lab. After this is created we head back into Dreamweaver to start coding the index all together. We first start by putting our heading banner which we learned in the previous lab. Then we inserted all 6 lab images using the <img> tag. An example was: <img src="Images/lab1.png" alt="Lab1" cla...

Lab 8 Reflection

During this lab the main goal was to create flash talk movie about one of the topics that we researched about.  A flash talk movie is a brief speech or presentation, intended to grab the attention of the audience and convey key information in a quick, insightful, and clear manner. The point of this flash talk was to describe in 2 minutes  the importance of the Internet and the effects on people and society. The three main topics given to choose from were Net Neutrality, Internet Censorship, Advanced option: Protocol Vulnerabilities and/or hacks. The topic I chose to talk about in this video was Net Neutrality. Net Neutrality is “Net neutrality is the principle that Internet service providers treat all data on the Internet equally, and not discriminate or charge differently by user, content, website, platform, application, type of attached equipment, or method of communication” (Wikipedia). This means that we as consumers of the Internet we are to surf freely among the web with...

" Minority and dissident communities face a perplexing challenge in countries with authoritarian governments. They need to remain anonymous to avoid persecution, but also must establish a trustworthy identity in their communications." Computer science and researchers traveled to three countries to help assess their challenges of maintaining a secure social media presence. They designed an app for android that would create a safeguard for the members for their anonymity and reliability of posts. The three countries were Mongolia, Zambia, and Turkey. These countries suffer from restricted speech, like Russia and China.  " The problem with anonymous communication is you don't know if it's credible," said Miriam Metzger.  This is where the app SecurePost comes into play because it allows the community to create secure groups on famous media, like Facebook, to maintain consistent presence on social media. The app allows total anonymity and flags any potential pos...
