The resistance: can viruses save us from drug-defying superbugs?

Losing weight is a struggle for many people and research has shown that one diet does not fit all, some people lose weight on a diet while others gain. For obese individuals, the way to lose weight may be highly personalized and involve a specific diet type, counting calories, or one of many different medications.

At least five people who were paralyzed are walking, thanks to a pain stimulator and physical therapy. The stimulator, which is implanted in the body, sends electricity to the spine, and combined with therapy, can retrain the body to walk again. “The first day I took steps on my own was an emotional milestone in my recovery that I’ll never forget, as one minute I was walking with the trainer’s assistance and, while they stopped, I continued walking on my own.”

"Farm to table" is a well-known saying in the food industry, but "lab to table" is also rapidly joining the rank of commonplace terminology. To both reduce the amount of animals killed and lessen the impact on the environment to raise livestock, researchers have found a way to manufacture cell-based meat that is created in a lab, yet still has the texture of meat.

As climate change continues to advance, its impact on farmlands has become more pronounced and increasingly devastating. Farmers and researchers in both South Africa and Nepal are working towards solutions to problems specifically related to climate change. Centered on developing technology, these farmers have found success with NASA satellite imagery as well as local clinics.

In California’s wildfire-prone Sierras, forest managers are turning to an ancient, if not quite intuitive, tool: more fire. In 2019, the Forest Service will manage 250,000 acres with controlled burns and “mechanical thinning,” using equipment to take out small trees. Though such plans face some hurdles, states across the country are adopting them, reducing wildfire severity while often benefiting ecosystems.

In countries like Cambodia, Angola, and Mozambique, rats are saving lives by detecting untriggered land mines. An international nonprofit, Apopo, provides funding a training and works with local organizations to operate at the local level. The rats are light enough that they don’t trigger the explosives and can cover up to 2,000 square feet in just 20 minutes – something that would take a human up to four days to complete.

Researchers from the University of Colorado and Colorado Parks and Wildlife are hoping the experimental antifungal bacterial baths they gave toads in the Rocky Mountains are working. A fungus called Batrachochytrium dendrobatidis has been killing amphibians around the world, but researchers think they may have found a way to stop it. In the lab, the experimental bath showed a 40% decrease in mortality, indicating promising results in the wild.

Scientists have been mapping microbes in public places for a long time and are now tracking Covid-19 by swabbing subways, park benches, ATMs, and even the air, for traces of genetic material to better understand the virus’ transmission dynamics and detect hotspots before transmission becomes widespread. Molecular monitoring has identified how long the virus can live on different surfaces and the origin of different strains, which can flag sanitation priorities and help contact tracers. There are limits to what it can reveal because finding virus on surfaces does not always lead to definite infection.

Genetic genealogy's use in criminal cases has gone mainstream. As the cases of three murder victims in Indiana illustrate, the science of DNA evidence combined with genealogical research and detective work is rapidly ramping up, from a hobby to a curiosity and now to a major commercial and criminal-justice opportunity. Hundreds of missing persons have been identified from decades-old remains, or murder suspects identified from old biological evidence in cold cases. By creating a family tree of the victim or suspect, investigators can zero in on an identity more quickly and inexpensively than ever.

Drug Aid Africa sources unused, unaltered drugs from people who don’t need them anymore and distributes them to people who do need them but can’t afford or access them. Drug Aid Africa provides free routine medications for conditions like sickle-cell anemia, as well as antimalarials, antibiotics and frequent visits to communities where they provide healthcare support and supplies. So far, the organization's efforts have helped more than 10,000 people.
