A sensor could monitor gut health via engineered bacteria

Posted by in categories: bioengineering, biotech/medical, health

Esearchers have devised a new way to get a sneak peek into what’s going on deep in your digestive system, creating a swallowable sensor that, with the help of engineered bacteria and a tiny electrical circuit, can detect the presence of molecules that might be signs of disease and then beam the results to a smartphone app.

The device, which scientists validated in pigs, remains a prototype and needs to be refined before it could be used in people. But the researchers, who reported their work Thursday in the journal Science, combined innovations in synthetic biology and microelectronics to create a modular platform that could be adapted to identify a wide range of molecules.

Measles makes alarming return to Europe and the Americas

Posted by in categories: biotech/medical, economics, health, neuroscience

Why it matters: Measles is a killer disease. It’s estimated that more than 2 million children a year died from measles in the 1980s, but due to global vaccine programs (including Gavi, the Vaccine Alliance launched in 2000), that number has been brought under 70,000 cases. The return of measles to Europe and the Americas could suggest that some of our vaccine successes could be reversing or unraveling. In the case of Venezuela, measles outbreaks are mostly due to the effect of broad economic problems on its health care system, but for Europe and the U.S. measles outbreaks show the effects of powerful and well-organized anti-vaccine movements.

What’s next: Vaccines do not cause autism, but more advocacy is needed to counteract the false claims of anti-vaccine groups. In April 2018, the European Commission proposed activities to strengthen the EU’s capacity to vaccinate its population and address what some call “vaccine hesitancy.” In the U.S., however, there are still 18 states that allow non-medical vaccine exemptions linked to personal or philosophical beliefs.

Peter Hotez is a professor and dean of the National School of Tropical Medicine at Baylor College of Medicine, where he is also director of the Texas Children’s Hospital Center for Vaccine Development, and the author of “Vaccines Did Not Cause Rachel’s Autism.”

Swallowable ‘bacteria on a chip’ could help diagnose colon cancer, bowel disorders and gut ulcers

Posted by in categories: biotech/medical, computing, genetics, health

Unlike other ingestible chips, this new version by MIT contains millions of genetically engineered living cells to act as sensors, designed to light up when they detect bleeding.

It’s the latest advance in a growing field of sensors that can be swallowed or worn to monitor our health.

Pills equipped with cameras, thermometers and acidity gauges already look for disease and track digestion.

New robots set to transform farming

Posted by in categories: food, health, robotics/AI

The Robots are Coming!


European consumers expect a clean supply chain and biodiversity to be conserved. Therefore, reducing the inputs of pesticides and chemical fertilisers to a minimum and/or replacing them by agro-ecological or robot solutions is required. Furthermore, the average age of European farmers is among the highest of all sectors, thus farming needs to attract young people with attractive working opportunities.

This is where the new agricultural robot solution for precision farming developed within the context of the EU Flourish (Aerial Data Collection and Analysis, and Automated Ground Intervention for Precision Farming) project can play a part. Use of robots in precision farming has the potential not only to increase yield, but also to reduce the reliance on fertilisers, herbicides and pesticides through selectively spraying individual plants or through weed removal.

Quantum dots made from tea leaves lay waste to lung cancer cells

Posted by in categories: health, quantum physics, solar power, sustainability

Full of antioxidants and vitamins, tea is pretty good for you, and green tea extracts have even been used as effective carriers for cancer drugs. New research led by Swansea University has found a novel way to wring more health benefits out of the stuff, by making quantum dots from tea leaves and using them to slow the growth of lung cancer cells.

Quantum dots are semiconductor particles so small they exhibit strange electrical and optical properties, such as the ability to fluoresce in different colors, or help with certain chemical reactions. Their glowing properties mean they’re showing up in TVs and solar cells, and in medical applications as biomarkers to help doctors precisely locate tumors. They’re also being used to treat cancer, fight antibiotic-resistant bacteria and convert CO2 into liquid fuels.

The problem is, manufacturing them can be a costly and complicated process, and the end results can be toxic. So the Swansea team, along with researchers from Bharathiar University and K. S. Rangasamy College of Technology, set about making quantum dots out of humble tea leaves.

Physical exercise doesn’t slow down dementia once it appears, study shows

Posted by in categories: biotech/medical, health, neuroscience

Physical exercise is a key piece of the brain health puzzle, but certainly not a magic pill.


___ Exercise ‘doesn’t slow’ progression of dementia (NHS Choices): A trial in which people with dementia took part in a moderately intense exercise programme for 4 months found their mental decline did not slow and may even have worsened faster than in people who did not take part in the programme…While the exercise.

Almost everything you know about e-waste is wrong

Posted by in categories: computing, economics, health

Many of us think we know what electronic waste is because we wonder what to do with devices we no longer want or need.

It’s the old cellphone and its charger stuffed in the drawer.

It’s that old laptop, monitor or printer packed behind the door or in the basement.

CDC Map Shows Every State Affected by the Salmonella Egg Outbreak

Posted by in categories: biotech/medical, food, health, sustainability

If someone tells you to go suck an egg, you might want to think twice about it if you live on the east coast. The United States Centers for Disease Control and Prevention announced last month that a Salmonella outbreak affecting hundreds of millions of eggs had been traced back to a farm in Hyde County, North Carolina. Public health officials have traced consumers’ illnesses in nine different states to the outbreak. Last week, the CDC released a map showing the outbreak’s spread.

Rose Acre Farms, the company responsible for the outbreak, distributes eggs all over the US, to both grocery stores and restaurants. As a result of contamination on the North Carolina farm, over 206 million eggs were exposed to Salmonella braenderup, a bacteria that causes severe diarrhea. The outbreak began in mid-April and appears to be slowing down, but in a multi-state outbreak like this, officials at the CDC may not hear about people getting sick right away. Therefore, the data on the case continues to evolve as reports roll in. The most recent numbers count 35 illnesses, 11 hospitalizations, and no deaths. Here’s a map of the outbreak’s current extent:
