Protection against many common pathogens and environmental stressors is written into our DNA. Our skin responds to sun exposure. Our immune system mounts defenses when we get the flu. Our bodies inherently work to mitigate the potential for harm caused by these health threats. However, these intrinsic responses are not always quick, robust, or appropriate enough to adequately defend us from harm, which is why many people experience sunburn after intense sun exposure or suffer severe symptoms, even death, following exposure to the flu.

Military service members, first responders, and civilian populations face threats far more severe than sunburn and respiratory infections. Pathogens with pandemic potential, toxic chemicals, and radioactive materials can all quickly and powerfully overwhelm the body’s innate defenses. And though significant public and private investment has been focused on the development of traditional medical countermeasures such as drugs, vaccines, and biologics to guard against the worst effects of these health threats, current countermeasures are often limited in their effectiveness and availability during emergencies.

DARPA is looking to make gains beyond the status quo. Inspired by recent advances in understanding of when and how genes express their traits, DARPA’s new PReemptive Expression of Protective Alleles and Response Elements (PREPARE) program will explore ways to better protect against biological, chemical, or radiological threats by temporarily and reversibly tuning gene expression to bolster the body’s defenses against – or directly neutralize – a given threat.

Amazing how quickly things are changing in brain health and mental health — see the news about Interaxon, Akili, NeuraMetrix, Apple, Calm, Halo Neuroscience, Mindstrong Health, Calm, Novartis, Pear Therapeutics, in the last 6 months alone, and consider joining the discussion in December smile (link opens 2-minute video)

Imagine a videogame cleared by the FDA to treat ADHD, depression, or substance abuse — how will doctors prescribe it, patients access it, and insurers pay for it?

Imagine a free “annual brain check-up” — what may it look like, and how can it lead into personalized interventions to improve function and prevent/ delay/ treat cognitive decline and Alzheimer’s Disease?

Imagine being responsible for the health & wellness of a million people — how will you educate them to navigate most-likely-to-help interventions, such as breathing/ exercise/ meditation/ apps/ biofeedback/ tDCS to regulate stress?

Imagine investing $100 million in startups developing noninvasive, digital neurotechnologies — where, and how, will you find great opportunities to generate financial and social returns?

It is rush hour and you are crammed inside a train carriage with a stranger’s armpit pressing against your face. Are you feeling relaxed?

Studies have shown that repeated infringement of personal space in cities can trigger the brain’s threat system, which makes us feel stressed.

Other factors such as constant contact with strangers and traffic noise all contribute to city dwellers being most likely to suffer from chronic stress.

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.

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.”

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.

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.

Helping farmland flourish

Precision farming combines technologies that customise the care that plants receive without increasing labour on the farmer’s side. The project consortium targeted the development of innovative agriculture techniques by monitoring key indicators of crop health and targeting treatment only for plants or infested areas that require it.

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 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.
