Once every few hundred thousand years the magnetic poles flip so that a compass would point south instead of north. While changes in magnetic field strength are part of this normal flipping cycle, data from Swarm have shown the field is starting to weaken faster than in the past. Researchers think power grids and communication systems would be most at risk. Is there work that you are engaged in that could help mitigate the effects of our world turning ‘upside down’???
Changes measured by the Swarm satellite show that our magnetic field is weakening 10 times faster than originally predicted, especially over the Western Hemisphere. The Swarm satellites not only pick up signals coming from the Earth’s magnetic field, but also from its core, mantle, crust and oceans.

People are usually given a breathalyser test to determine whether they are over the legal limit for alcohol consumption. Here’s a more pleasant application of this testing – - -

Perhaps current human breathalyzer testing will expand to being a diagnostic tool for people, too! There are ideas in the works – check out this article: Sports concussion ‘breathalyser’ proposed Scientists at the University of Birmingham in the U.K. are developing a “breathalyser” to detect concussions, which will be used to prevent brain injuries among athletes, especially children.
And, should you manage to pick up the April 2014 issue of Journal of Medical Engineering & Technology, there’s an interesting research article on this topic [Designing breathalyser technology for the developing world: how a single breath can fight the double disease burden (Authors: Sarah Krisher, Alison Riley, and Khanjan Mehta, Vol. 38, No. 3 , Pages 156-163(doi:10.3109/03091902.2014.890678)] Abstract: The meteoric rise in the prevalence of non-communicable diseases, alongside already high rates of infectious diseases, is exacerbating the ‘double disease burden’ in the developing world. There is a desperate need for affordable, accessible and ruggedized diagnostic tools that detect diseases early and direct patients to the correct channels. Breath analysis, the science of utilizing biomarkers in the breath for diagnostic measures, is growing rapidly, especially for use in clinical diagnostic settings. Breathalyser technologies are improving scientifically, but are not yet ready for productization and dissemination to address healthcare challenges. How does one ensure that these new biomedical devices will be suitable for use in developing communities? This article presents a comprehensive review of breath analysis technologies followed by a discussion on how such devices can be designed to conform with WHO’s ASSURED criteria so as to reach and sustain in developing countries where they are needed the most.
Cities, citizens and businesses all have a role to play when it comes to creating smarter and sustainable systems to plant, grow and distribute food. For a taste of some companies that are trying to make a difference, read about these three innovative ideas.
Lab to Fork: Growing Meat to Save Animals, Environment
The idea of beef produced in a petri dish may be hard to swallow for some, but one start-up believes the concept will grow on people. Brooklyn, New York-based Modern Meadow Inc. is developing what it calls bio-fabricated meat by using a technology called tissue engineering. By cultivating muscle cells in a vat to produce meat protein, the company hopes to reduce the slaughtering of animals and create a more humane food-supply system. Modern Meadow also says lab-grown meat offers a more sustainable and economical alternative to the traditional livestock industry because of fewer greenhouse-gas emissions and less land and water use.
Where Tunnel-Raised Lettuce Is the Bomb
For a group of sustainable farmers in London, there’s light at the end of the tunnel. LED light, to be exact. It’s helping them grow heads of salad in abandoned WWII bomb-shelter tunnels 33 meters underground, near the Clapham North subway station. A company called ZeroCarbonFood finds the subterranean space perfect for raising lettuce and micro greens through hydroponics, or gardening without soil. ZeroCarbonFood says the system uses 70 percent less water than conventional farming and is pesticide-free. The group, which is leasing the tunnels from Transport London, aims to sell the produce to high-end restaurants as well as through retail markets, and boasts that the turn-around time from picking to customer delivery is as little as four hours.
Saving Bees and Creating a Buzz
Global honeybee colonies have been endangered by pesticides and other pathogens, putting crops that depend on pollination such as almonds, berries, fruits and vegetables at risk, as well as honey supplies. To help restore colonies and to promote awareness of the issue, Philips has designed what it calls the urban beehive, which permits indoor beekeeping at home. The sleek and pod-like beehive has a glass shell that contains honeycomb-like frames, which allow bees to build their wax cells. By pulling on a chain, smoke can be released into the hive to calm the bees before it’s opened to allow honey harvesting.

For those of us fortunate enough to have been granted the full use of all of our limbs throughout all of our life, it is nearly impossible to understand the challenges faced daily by those who don’t have unlimited mobility. There are numerous charities around the world that work tirelessly to collect funds for research. There are countless hospitals and clinics staffed by caregivers and rehabilitation specialists.
This story is about the brilliant work of a man whose own physical abilities have been reduced – and his gift of new mobility to others who need a helping (robotic) hand…
Invented by Dr. Goffer, the Founder and President and Chief Technical Officer of ReWalk Robotics, the ReWalk allows paraplegics to stand upright, walk and in some cases climb stairs. He is a graduate of Technion University in Israel. An Israeli inventor who became quadriplegic after an ATV accident in 1997, it was through his own personal experience in utilizing mobility devices for people with spinal cord injury that Dr. Goffer developed the ReWalk.
