anonymous asked:

could you explain how important advanced math is, even for folks who aren't going to go into fields of work requiring advanced math?

maths is what lets new and better technology be made, new analysis techniques for experimental and real-life data, prediction of crimes (mathematical criminology is a real thing it’s so interesting), prediction and prevention of disasters, weather forecasting, did I say better technology, medical equipment improvements, al sorts. Advanced maths is what lets us understand what we’re doing and what the world around us is doing, and its applications are without a doubt endless. Maths is still shit

Doing some advanced reading (or highlighting??? haha) for tomorrow’s first Parasitology lecture. I’ve had a brief encounter with parasites from last semester’s Clinical Microscopy during our lectures and lab activities on Fecalysis. I guess I better start getting used to dealing with stool samples twice a week for the next few months to get to know more about these organisms haha.

Quick DNA Tests Crack Medical Mysteries Otherwise Missed

Researchers are developing a radical way to diagnose infectious diseases. Instead of guessing what a patient might have, and ordering one test after another, this new technology starts with no assumptions.

The technology starts with a sample of blood or spinal fluid from an infected person and searches through all the DNA in it, looking for sequences that came from a virus, a bacterium, a fungus or even a parasite.

Scientists at the University of California, San Francisco are reporting this week their first results from the technique, which relies on a technology calledNext Generation Sequencing.

One of their early patients is Andrea Struve, a 21-year-old San Franciscan who returned from 40 days in the Australian Outback last year with a nasty set of symptoms.

“I was in classes, sweating profusely with a fever and joint pain, and it just wasn’t fun, so that’s when I went to the doctor,” she says.

Her doctor made a bunch of educated guesses about the underlying cause, but all the tests came back negative. So physicians enrolled Struve in a study at UC San Francisco to try out a different approach.

“As opposed to the way we normally diagnose infectious disease — meaning we target a single infectious agent at a time — this test works by detecting all the DNA present in clinical samples,” says Dr. Charles Chiu, who is running the study.

Chiu extracted DNA from Struve’s blood and ran it through a superfast sequencing machine. He compared the DNA he found with a huge library of DNA sequences from all sorts of infectious agents. It turns out that she was infected with a virus related to chicken pox — one that normally causes a roseola rash in young children.

3D Printers Can Now Churn Out “Living” Blood Vessels
In a breakthrough that could lead to printable organs and an enhanced understanding of human physiology, researchers from Lawrence Livermore National Labs have 3D-printed functional blood vessels that look and function like the real thing.
By George Dvorsky

In a breakthrough that could lead to printable organs and an enhanced understanding of human physiology, researchers from Lawrence Livermore National Labs have 3D-printed functional blood vessels that look and function like the real thing.

3D bioprinters are similar to conventional 3D printers, but instead of using inert materials, they use “bio-ink:” basic structural building blocks that are compatible with the human body.

To create the 3D-printed blood vessels, a LLNL team headed by research engineer Monica Moya combined this special biomaterial with living cells. The material and environment were designed to enable small blood vessels, or human capillaries, to develop on their own. A release from LLNL explains:

This process takes a while, so initially, tubes are printed out of cells and other biomaterials to deliver essential nutrients to the surrounding printed environment. Eventually, the self-assembled capillaries are able to connect with the bio-printed tubes and deliver nutrients to the cells on their own, enabling these structures to function like they do in the body.

“If you take this approach of co-engineering with nature you allow biology to help create the finer resolution of the printed tissue,” Moya said. “We’re leveraging the body’s ability for self-directed growth, and you end up with something that is more true to physiology. We can put the cells in an environment where they know, ‘I need to build blood vessels.’ With this technology we guide and orchestrate the biology.”

The resulting blood vessels cannot be transplanted, but they’re suitable for toxicology studies and medical treatment testing (which will lead to a decreased dependency on lab animals), and Moya says they will provide a test bed for fundamental science.  What’s more, 3D bioprinting efforts like these could eventually lead to so-called organs on a chip, which will help to alleviate the current organ donor shortage.

The LLNL scientists will soon be able to utilize a brand new 3D bioprinting lab equipped with a more precise printer capable of higher resolution and larger structures.

“It’s going to change the way we do biology,” said Moya.

YEAH, SCIENCE!

UK Woman Gets “World’s Most Advanced” Bionic Hand Replacement

A new technology has enabled a woman who was born without a right hand to ride a bike for the first time, among other new abilities.

Steeper Group, which is based in Leeds, created the “BeBionic” small hand for Nicky Ashwell, a 26-year-old from London; the company claims it is the most “anatomically accurate” out there and offers an “unrivalled level of precision and natural movements”.

EVERYONE W/ A CAMERA: RECord yourself on camera answering these three specific questions RE: Future Technology: 

  1. How would you feel about the self-driving car? Would you feel out of control? Do you think it seems dangerous? Do you think it would reduce the death rate of car accidents? 

  2. How do you feel about the idea of brain chips? Does it sound fun or scary to you? 

  3. How do you feel about medical technology evolving to the point of making immortality a reality? Is the point of life that it’s finite?

I’m loving the current look of my study table. I recently bought a snake plant because I’ve been dying to have at least one succulent plant in my bedroom for months now haha. Now I’ve finally got one!

I also recycled an old reagent bottle and filled it with tiny scrolls of inspirational messages that our university library has been giving to the students daily.

Please Help!!!

As some of you know, my father left his job as a pediatrician so that he could create an application that makes it easier for doctors and patients to communicate and share information. It has been a really hectic year with trying to launch a business and my dad has spent nearly all his waking hours putting his heart into this project. unfortunately, doctors are reluctant to try it out- even for free. He’s nearly defeated and it breaks my heart…

Currently there is a huge medical conference/contest that could be the last big chance to turn the app around. The top 4 medical ideas are selected for a paid conference at Harvard! The catch is- to vote you must be a doctor or med student… if any of you ARE either, or know either, or would consider signal boosting this, I will be forever grateful!!

Please share this with any med students and doctors, even if they don’t vote maybe they will like the idea and want to be involved!!

Thank you so much and best wishes- this means more to me than I can explain. I know it’s a really long shot to gain awareness through my art and plant blog, but the internet is surprising.

One of the most fascinating aspects of emerging medical technology is how close we’re coming to being able to map and understand an entire human organism in real time. The gifs above come from GE’s new Revolution CT Scanner, a technology that exists today. Imagine what will exist tomorrow. In coming years, we may be able to push past the mapping of blood flow to begin mapping interactions between neural synapses, the reactions that make up our consciousness, that determine the most fundamental aspects of who we are. And once we can map our consciousness in real time, what’s to prevent us from replicating it?

3-D Printers Help Grow New Jaws For Dogs At UC Davis

Previously, the doctors had to wait until they cut into the dog to form the titanium plate. But with UC Davis’ new 3-D printing facility, they can now print an exact replica of the dog’s skull ahead of time, allowing doctors to plan and cut down on anesthesia time in the operating room.<br/>

The future is here.

Scientists look deeper into the body with new fluorescent dye

Glowing dyes help scientists see inside the body and diagnose ailments, but they needed a certain type of molecule to improve the imaging depth. They invented a long wavelength near-infrared fluorescent molecule, and it works.

In recent years, physicians and researchers have increasingly turned to glowing dyes to look beneath the skin. An eye doctor, for example, might inject a dye into a patient’s blood before shining a bright light in her eye. The dye causes the blood vessels to glow, providing a roadmap of the patient’s retina on a computer screen.

At Stanford and elsewhere, researchers have worked to create dyes that, when stimulated, emit light of long wavelengths close to infrared light. Such a light, which is not visible to the human eye, could then be viewed by a special camera and be projected to a monitor to produce deeper, sharper images from inside the body.

This fluorescent imaging can help to pinpoint tumor locations near the skin’s surface in a variety of cancers, such as head and neck, melanoma and breast cancer.
