A collaborative project between 3D image analysis software company Lume VR Ltd. and scientists at the University of Cambridge showed off a new virtual reality tool today that gives scientists a new view of the inner workings of human cells.

The researchers hope the Google Street View-style tool will provide an up close and personal way to understand fundamental problems in biology to help new treatments for disease. The details are published in the scientific journal “Nature Methods.”

By using VR, scientists can “walk” through the “byways” and “highways” within the cells themselves and see proteins fold and unfold. They also can potentially see where things go wrong when they go wrong and even rewind biological processes by looking through recorded and visualized datasets.

The software, vLUME, uses super-high-resolution microscopy data that is collected, collated and digested. After that, the data needs to be rendered in a manner understandable by

Virtual reality software which allows researchers to ‘walk’ inside and analyse individual cells could be used to understand fundamental problems in biology and develop new treatments for disease.

The software, called vLUME, was created by scientists at the University of Cambridge and 3D image analysis software company Lume VR Ltd. It allows super-resolution microscopy data to be visualised and analysed in virtual reality, and can be used to study everything from individual proteins to entire cells. Details are published in the journal Nature Methods.

Super-resolution microscopy, which was awarded the Nobel Prize for Chemistry in 2014, makes it possible to obtain images at the nanoscale by using clever tricks of physics to get around the limits imposed by light diffraction. This has allowed researchers to observe molecular processes as they happen.

It sounds like something out of science fiction films such as Inception, but a new gadget has allowed MIT scientists to plant ideas in people’s dreams. 

Researchers used an app combined with a sleep tracking device to “plant” ideas in people’s minds as they slept. 

The monitor waits for people to enter a suggestible stage of sleep, then the app plays a message telling them to think about trees.

Two-thirds of volunteers who heard the prompt, went on to dream about trees.

The researchers describe the technique as “targeted dream incubation”, LiveScience reported. 

The research relies on the sleep-tracking device (called Dormio) detecting an early sleep stage known as “hypnagogia”.

Hypnagogia (the earliest sleep stage) is similar to the REM stage, but people can still hear audio during hypnagogia while they dream. 

Lead researcher Haar Horowitz said, “This state of mind is trippy,

Imagine strapping on a wearable device before you hit the bed. You fall asleep, and at a certain point, the gadget guides your dreams and even records them. This is not a work of science fiction — but a reality, created in a lab at Massachusetts Institute of Technology (MIT).

MIT scientists have developed a sleep-tracking gadget named Dormio. It can alter dreams by manipulating a sleep stage called hypnagogia, which occurs when the mind transitions from experiencing drowsiness to a time when it loses consciousness. Individuals that enter hypnagogia can hear audio while they dream, unlike the Rapid eye movement (REM) stage, where most of the dreaming happens. They have published their findings in the Journal Consciousness and Cognition.

The device may help boost creativity or improve memory. It may help build new commercial technologies that can affect sleep onset, sleep quality, sleep-based memory consolidation, and learning, Dr Pattie

Seven years ago, my student and I at Penn State built a bot to write a Wikipedia article on Bengali Nobel laureate Rabindranath Tagore’s play “Chitra.” First it culled information about “Chitra” from the internet. Then it looked at existing Wikipedia entries to learn the structure for a standard Wikipedia article. Finally, it summarized the information it had retrieved from the internet to write and publish the first version of the entry.

However, our bot didn’t “know” anything about “Chitra” or Tagore. It didn’t generate fundamentally new ideas or sentences. It simply cobbled together parts of existing sentences from existing articles to make new ones.

Fast forward to 2020. OpenAI, a for-profit company under a nonprofit parent company, has built a language generation program dubbed GPT-3, an acronym for “Generative Pre-trained Transformer 3.” Its ability to learn, summarize, and compose text has stunned computer scientists like me.

Do Computer Scientists Use Math?

May 3, 2020 | computer | No Comments

Recently a student, “James”, asked if it was possible to him to work in the computer field, even if he doesn’t like math and says he is not good at it.

The short answer: yes. The longer answer? Yes and no.

There is a huge opportunity for development of all kinds of software and hardware that doesn’t require mathematics, per se. Fields like software/app design and UX (user experience) quality assurance require understanding of the language involved and how the software interacts with the overall hardware, but not deep mathematics.

So James can certainly make a good career working with computers without knowing his epsilons and deltas.

But will math be useful?

Some areas – like some of the formulas we memorize in calculus class – will not be useful. But others, like discrete mathematics – will prove very useful to James: they will teach him concrete concepts he can … Read More

R is an open source programming language which has quickly gained huge popularity in the statistical software industry. With millions of statisticians and data scientists using this language all over the world, its popularity is expected to grow rapidly in the coming years. R can be considered as a statistical analytical package which includes all types of models, tests and analyses for manipulation and management of data. Those who wish to grow their career in the world of data science should definitely opt for R Programming Training.

Why R Programming Language is Hugely Popular among Data Scientists

R offers businesses with the most sophisticated and advanced business analysis tools that help them to utilize data in the most efficient manner. Discussed below are some of the reasons as to why it is preferred by data scientists:

Open Source

The best part about R is that, it is open source. This … Read More
