A new class of antibiotics to fight against drug resistant superbugs

Scientists trawling through thousands of soil samples have discovered a whole new class of antibiotics capable of killing drug-resistant bacteria. The chemical, which has been called malacidin, appears to be non-toxic in humans and effective in tackling the hospital superbug MRSA, raising hopes that it could be used to develop a new treatment. www.inkl.com/newsletters/morning-edition/news/new-type-of-antibiotic-discovered-in-soil-in-breakthrough-for-fight-against-drug-resistant-superbugs?

Drug addiction prevented by vaccination

istock-502686281 (1)

One of the best defences we have against viral infections is vaccination. Vaccines prime the body’s immune system to fight an incoming infection and have been credited with the widespread eradication of smallpox and the near-eradication of polio. There are nine vaccines currently in development that could dramatically change how humans live. They include vaccines for cancer, HIV, malaria and drug addiction. https://www.nbcnews.com/mach/science/anti-drug-vaccines-could-be-game-changer-people-battling-addiction-n749416

Tobacco companies forced to tell the truth in advertising

5CD63CB4-D974-427A-A34A-1947FDF88E3B

Major American cigarette manufacturers are now publishing anti-smoking ads to correct the misleading statements they made over many years about the effects of smoking, a move that complies with a court order filed in 2006. The ads explain that smoking kills and cigarettes are intentionally designed to get people addicted. https://www.washingtonpost.com/business/big-tobaccos-anti-smoking-ads-begin-after-decade-of-delay/2017/11/21/8841d418-ce82-11e7-a87b-47f14b73162a_story.html

A glue that could save lives

IMG_2408

Australian and American biomedical engineers have developed a stretchy surgical glue that rapidly heals wounds. It’s seen as a breakthrough that has the potential to save lives in emergencies. The injectable glue, MeTro, is based on a naturally occurring protein. It’s applied directly to the wound and then activated with UV light to form a complete seal, eliminating the need for staples or stitches. Its elasticity means it’s designed to work well on shape-changing internal organs like the lungs and heart. http://www.news.com.au/technology/science/human-body/injectable-stretchy-glue-that-heals-wounds-in-60-seconds-could-save-lives/news-story/f00161d15e7ae014d01380e5dba40ffc

New cancer treatment- gene therapies

IMG_2263

Scientists are researching ways of deactivating or repairing faulty DNA within people’s bodies, another pathway that could lead to breakthrough cures. Specialists take a patient’s immune cells and reprogram them with a new gene that instructs them to detect and kill specific cancer cells. They then inject those reprogrammed cells back into patients’ bodies, where they go to work destroying deadly malignancies. In a clinical trial, 83 percent of patients saw remission within three months. This technique is one of several classified as “gene therapies.” https://www.washingtonpost.com/opinions/a-new-cancer-drug-may-be-the-first-in-a-line-of-revolutionary-treatments/2017/09/10/d1526d92-8e82-11e7-8df5-c2e5cf46c1e2_story.html?

A new way to diagnose and treat disease

IMG_2322

The effectiveness of smart pills, biosensors and drug-delivery systems depends on the surrounding tissue inside the body. To overcome this, researchers from Cal Tech have created a mini wireless chip that can vary its output frequency in relation to a local magnetic field, enabling a precise location to be determined. In addition to one day measuring factors such as pH, blood sugar, and temperature inside the body, developments like this should enable massive improvements in our ability to diagnose and treat disease as well as possibilities for life extension. http://www.kurzweilai.net/miniature-mri-simulator-chip-could-help-diagnose-and-treat-diseases-in-the-body-at-sub-millimeter-precision?

Diagnose skin cancer with your smart phone

IdeaSpies skinvision_-1200x0

Worried about a strange mole on your body? Imagine being able to receive a diagnosis through your smartphone so you can decide whether to visit your doctor before your next scheduled visit. That’s the broad idea behind a recent project created by computer scientists at Stanford University, which applied the extraordinary machine vision powers of cutting-edge deep learning neural networks to the world of dermatology. www.digitaltrends.com/cool-tech/deep-learning-algorithm-cancer/#ixzz4X0xkOJ

A 10 sec check for cancer

IMG_2288

Scientists from the University of Texas at Austin have developed a pen called the “MacSpec pen” that can screen and analyze tissue samples for cancer in just 10 seconds when the process usually takes weeks. The pen, which looks like a white permanent marker with a cord down its back, is made with a 3D-printed surgical-ready plastic tip and uses water instead of gases and other harming solvents. The tool works by releasing a small water droplet onto a tissue sample and sucking the water, with some residual tissue, into a mass spectrometer to analyze the tissue samples in real time. With 93 percent accuracy, the researchers identified lung, ovary, thyroid and breast cancers using both mice and human tissue samples. https://www.google.com.au/amp/newatlas.com/macspec-pen-cancer-healthy-tissue/51238/%3famp=true
