Superbugs That Resist Antibiotics Can Evolve in 11 Days | I Contain Multitudes

Published

Antibiotics like penicillin have a critical role in medicine, but using them is not a decision to be taken lightly.

Before the discovery of penicillin and other antibiotics, a cut on your knee or an ear infection could kill you. In 1928, a physician named Alexander Fleming found that a mold in one of his petri dishes was killing the bacteria he was trying to grow. This strain of mold formed the basis for one of the most significant medical discoveries in history: penicillin. Antibiotics soon became lifesavers, and so precious that unused penicillin was reclaimed from patients’ urine to give to others. However, even back then, Fleming knew that bacteria could become resistant to penicillin. In this episode, Ed Yong explains how serious the situation can become: “Bacteria have always been evolving ways of resisting the things that try to kill them. And now the overuse of antibiotics is exacerbating that problem.” Ed looks at shocking new footage of mutating bacteria thriving in antibiotics a thousand times stronger than can kill their non-superbug ancestors.

    An important message – we all have to do our part to not take antibiotics for granted. Thanks for another great video!

    Good show, but I want to know. What ARE viruses? You don't have to make a video and some commentor may explain.

    Great video, thanks. Let's not forget that although Fleming discovered penicillin, it was actually Florey and Chain in the midst of WWII that turned it into medicine. All three shared the Nobel prize in 1945.

How NeuroTechnology is Changing Our Lives

Published

By



Who among us anticipated that in 2015 we would be talking through our steering wheels while driving? From the basic ways we communicate to how we pay bills and make purchases, technology is transforming our lives. Add neuroplasticity, the scientific discovery that our brains change throughout our lives, to the mix, and what lies ahead becomes even more interesting.

Zack Lynch, Chairman and Founder of the Neurotechnology Industry Organization, will present his vision for the future and will moderate a conversation with:

Jen Hyatt, founder of Great Britain’s Big White Wall, a company that provides a 24/7 safe online community of people who are anxious, down or not coping, guided by trained professionals.

Corey McCann, MD, PhD, founder of Pear Therapeutics, a company that combines digital therapies with supplements, medical foods and pharmaceuticals to create more effective treatment solutions.

Jocelyn Faubert, PhD, whose laboratory at the University of Montreal has yielded technologies that led to the launch of CogniSens, a neurotechnology company that specializes in measuring, identifying and improving neurobiological activity, whose practical applications are used for attention training, in the identification of mild perceptual impairment related to a variety of illnesses, and by professional sports teams and elite military forces.

Professor Merryn Tawhai – Digital Breaths: The benefits of bioengineering (2018)

Published

Royal Society Te Apārangi | 2018 NZ Research Series
Digital breaths: The benefits of bioengineering

An aging population and increase in people living with chronic disease calls for new approaches to reduce healthcare costs and improve patient outcomes. Recent advances in imaging, sensor, and communications technologies, combined with innovative bioengineering approaches, has the potential to revolutionise healthcare. However, does New Zealand have the capability to become a world leader in this industry?

Professor Merryn Tawhai explains how each stage of this multi-disciplinary process, from a science discovery through to the applied science and then clinical research, are each critical to developing both technology and devices that can reduce the burden of chronic disease. Merryn’s own research advances computer modelling of the human lung in search of better methods to diagnose and treat lung disease, particularly in the older generation.

About the speaker:
From a keen interest in biology and mathematics in her youth, Professor Merryn Tawhai is now the Director of the Medical Technologies Centre of Research Excellence (MedTech CoRE) and Deputy Director of the Auckland Bioengineering Institute at University of Auckland.

At the 2016 New Zealand Research Honours, Merryn was awarded the MacDiarmid Medal by Royal Society Te Apārangi for her research to create anatomically detailed models of the respiratory system. The medal is awarded for outstanding scientific research that has the potential for human benefit, and the models created by Professor Tawhai provide new tools for diagnosis, prognosis and treatment of lung disease.

This talk was held at Royal Society Te Apārangi in Wellington on Thursday 21 June and was proudly presented in partnership with the Auckland Bioengineering Institute of University of Auckland and the Medical Technologies Centre of Research Excellence (MedTech CoRE).
