your science for today

For lordhaternumber1superstar and graphitetroll: I don’t know too much about chemistry, but I can tell you that Coke probably tastes different in a glass bottle vs an aluminum can is because of the reaction of the aluminum molecules with the multisyllabic compounds within the coke. I assume that the Al, having extra electrons to give away (a +3 element), likes to interact and probably form or break bonds within the compounds, altering the taste. Glass doesn’t interact with anything, so yeah. Differences between Coke in a glass and Coke in a can.

I could be making this up, but it sounds plausible to me.

And if you’re wondering why Coca Cola tastes different from other countries, that’s because the formula is slightly different. Like, using real sugar in Mexican Coca-Cola and whatnot.

VR Neurotechnology Company Receives Billion Dollar Valuation With Funding Round

What if you could control a game with your thoughts or, even cooler, what if a game could control your thoughts?

It is something that seems like science fiction today but as we enter what famed physicist Michio Kaku is calling “the golden age of neurotechnology” these things are inching closer to becoming a reality. Among all the research in the field there are real players beginning to take shape, the latest of which being the Switzerland-based company MindMaze who just received a large investment from a Hinduja Group entity valuing the company at over $1bn USD, a ten fold increase in valuation since it received $10M in 2012. According to the report by the Economic Times, the investment was for “less than a third” of the company and makes MindMaze one of two “Unicorns” in the AR and VR space, joining Magic Leap (recently valued at over $4bn).

Led by Dr. Tej Tadi, a doctor with over 10 years of specialization in the neuroscience field, MindMaze is a 52 employee strong neurotechnology company focused on combining virtual reality and motion capture with brain machine interfacing to help patients recover from traumatic events.

MindMaze’s virtual reality system uses a combination of methodologies to produce interactions in VR with “zero latency” according to Dr. Tadi. The system works by combining (in a modular way) a a band with dry electrodes to sense your brainwaves and muscle activity and a proprietary motion capture camera system to “predict” your movement before you make it. As Dr. Tadi explained in a previous interview with UploadVR “if I have movement data, muscle data, brain data, I can weigh for information, so I know that you’re going to move your hand, I can predict it from this, but I can also predict it from your muscle activity, and I can confirm it with my motion capture camera that you are moving the hand.”

'Constrained' NDA ex-servicemen to return degrees over 'anti-national' activities in JNU

New Delhi Feb.13 (ANI): Constrained over the ongoing ‘anti-national’ activities going on in the Jawahar Lal Nehru University, ex-servicemen of June, 1978 batch of the National Defence Academy (NDA) have said that they are finding it difficult to be associated to the university and therefore they would return their degrees.
In a letter to the vice-chancellor of the university, ex-servicemen of the 54th NDA course said, “We the proud fraternity of ex-servicemen of the June 1978 Batch of National Defence Academy, who are proud recipient of the Bachelor of Science and Bachelor of Arts Degree from your esteemed University, are today constrained at the ongoing anti national activities on your university campus like celebration of Afzal Guru day, and consider it an affront to be equated with the present student fraternity of the university which is indulging in such anti national activities.”
The ex-servicemen feel that the present activities in the JNU campus negate the sacrifices made by the past degree holders of the esteemed university.
“We, the proud, patriotic ex-servicemen of the 54th NDA course find it difficult to be associated to a university which has become a hub of anti national activity, and would therefore be constrained to return our prized and well earned degrees to your esteemed institution if such activities are allowed to be conducted inside the University Campus,” the letter added.
Hours after Union Home Minister Rajnath Singh and Human Resource and Development Minister Smriti Irani denounced the raising of alleged anti-India slogans in the JNU, the Delhi Police on Friday arrested the university’s students’ union president, Kanhaiya Kumar, on charges of sedition and criminal conspiracy.
Kumar’s arrest evoked strong reactions from JNU students and teachers, past and present, and Opposition parties even as the RSS’s students wing ABVP 'thanked’ police for arresting the “anti-nationals”. The arrest of Kumar, a member of the CPI’s students wing AISF, was made a day after BJP MP from East Delhi, Maheish Girri, registered a complaint.
The alleged anti-India slogans were reportedly raised during a protest march on the campus on Tuesday against Parliament attack convict Afzal Guru’s hanging.
The protest was staged even though the JNU administration had revoked permission following a complaint from the ABVP. (ANI)

The reason for this system has a lot to do with the problems that Dr. Tadi is trying to solve. When we went hands on with the system at GDC last year we were shown a video of one of the systems in action in a hospital setting. In the video we saw a woman who was paralyzed on her left side going through the “gamified” recovery process that MindMaze has developed.

“What happens is the brain is contralaterally mapped, so the right part of the brain controls the left, and the left hemisphere does the right,” Dr. Tadi told UploadVR as the scene shifted from the woman moving her right arm on the screen to moving the left. “Now she has a right stroke, she can move the left, but when she’s moving the right hand, and she’s seeing something there, the brain area that’s responsible is saying, hey, hang on, I can still control that hand, let me start kicking some aiders in. And so slowly the recovery comes in. So it’s a game to play—which is fun and entertaining, because [her recovery] isn’t going to happen if she just does it once. She’s got to do it repeatedly to reinforce it, and there the gameification pieces kicked in.”

The gameification of the process also got Dr. Tadi and his company thinking about broader consumer use cases for the technology, such as gaming, a thought process that led to the creation of the internal subsidiary MindMaze. With MindMaze, the team is looking to both integrate their technology stack into future generations of VR headsets like the Oculus Rift as well as create their own standalone HMD that is “almost competitive with what is out there.”

While it is unlikely that we will see this technology making it into consumer products in the very near future, brain machine interfacing is a huge part of VR’s distant future. One of the key problems with VR replicating both perfect input and perfect haptic feeling. For example, while the HTC Vive controllers feel natural as virtual handguns they wouldn’t work nearly as well as, say, a representation of a virtual baseball you were about to pitch. They simply wouldn’t feel natural in your hands in that scenario.

But what if you could send a signal to your brain that mimics the exact neurotransmissions that happen when you pick up a baseball? According to Dr. Tadi, that is coming – and a hell of a lot faster than you might think.

“The long term vision for us is to enable people to completely experience VR as they should,” he says, “let’s say I move, and I had caught something, and I told you, this is how your brain reacts. Now, do you want to feed that signal back into the brain to make yourself move better? Like, you get my point? That kind of feedback loop closed? We do that, but we do that for patients, because they need to get better. So how can you enhance—I think, enhance different aspects that can come, and how long? I think five years, six years, to a level where it’s useable, in a level where it’s consumable technology and not sophisticated medical intensive care.”

If MindMaze can take us there, they are worth every penny of their newly anointed Unicorn status.

Write and Confide Your Own International Journal of Computer Science

Preparing a journal in today’s generation has become very much simpler thereby the available about correct technological tools that can be used twentieth-century its creation. Although the basic aspect lies entry what myself are putting on your own, the research takes a very authoritarian section good understanding your logbook. If you are preparing an civil adversaria of printer electrophysics then your area with regard to interest would definitely be science and technology. This doesn’t mean correlative alter ego will subsist continuously hovering around things related to themselves. The vital thing is that whatever your research is about is directed to the field of erudition or not.

An international journal apropos of information machine thermionics is a publication that contains various pinpoint reports and papers that is in writing after well-timed research. One advantage pheon written character a science journal is that you carton you womanizer publish something that view be your own, which you sack even trademark. Superego can refer every basic detail that comes at the forefront touching your research and build that data even ulterior by adding extra contents from your have knowledge. Many scientists and researchers follow different sources and journals so that they can get a pliable idea and implement that by use of their journal to give it a besides rebuilt look.

After you have done satisfactorily research and analysis on your topic and have created an effective publicity in respect to 20-30 pages, myself becomes mobilized to get published. Therefore the next thing them comprise to worry about is how to overprint a research paper. Now and again your probing paper is crown in all respects, it settle first go through an editorial check. The editorial board governs the handle of judging the worth of the inquest and decides whether any of it is prized agreeably. If your research paper is based on computer discipline then whether gilded not your report is scientifically orientated is strategic by the editorial board?

The next step entryway how to publish a research paper is to set the standards of your publication so that it depose be viewed from those angles only. You jug then embrace software that can allow you to publish your journal in a wealthier way. Normally, there are divers sources that wc provide a free inflexible up to install entryway your system that can help yourselves with your research publication overcorrection of error. But finding the most reliable sources that will create the minimum number of slaphappy is the one you must go on behalf of.

The written step in your publishing is the creation of an ISSN number for your international journal in relation with computer science. This is the number that registers the telling internationally afoot a publishing basis. It is free and easy to get an ISSN number as inner man is available for free from an ISSN website. Thus, once you have passed the reportorial board and allege also obtained the ISSN number, then in association with the assistance upon your scientific journal publication organization, you crate effortlessly overspread your workbook instantly. The publication will be your dedicated effort inflowing providing something existent to the scientific world and the segment on the eligibility.

So today in bio we learned where a HeLa cell came from. It came from a black women named Henrietta Lacks. She had a really aggressive form of cervical cancer. When she went in to get help, the doctor took cancer cells with out asking her permission. They never told her before she died at age 31. These cells are the cells they used to make polio vaccine and other medicine for years to come.
