One of the vast untapped potentials of medicine is the access to imaging equipment. A billion people have difficulty getting access to an x-ray, and that says nothing about access to MRIs or CAT scans. Over the past few years, [Jean Rintoul] has been working on a low-cost way to image the inside of a human body using nothing more than a few electrodes. It can be done cheaply and easily, and it’s one of the most innovative ways of bringing medical imaging to the masses. Now, this is a crowdfunding project, aiming to provide safe, accessible medical imaging to everyone.

It’s called Spectra, and uses electrical impedance tomography to image the inside of a chest cavity, the dielectric spectrum of a bone, or the interior of a strawberry. Spectra does this by wrapping an electrode around a part of the body and sending out small AC currents. These small currents are reconstructed using tomographic techniques, imaging a cross-section of a body.

[Jean] gave a talk about Spectra at last year’s Hackaday Superconference, and if you want to look at the forefront of affordable medical technology, you needn’t look any further. Simply by sending an AC wave of around 10kHz through a body, software can reconstruct the internals. Everything from lung volume to muscle and fat mass to cancers can be detected with this equipment. You still need a tech or MD to interpret the data, but this is a great way to bring medical imaging technology to the people who need it.

A common species of freshwater green algae is capable of removing certain endocrine disrupting chemicals (EDCs) from wastewater, according to new research from the Desert Research Institute (DRI) in Las Vegas.

EDCs are natural hormones and can also be found in many plastics and pharmaceuticals. They are known to be harmful to wildlife, and to humans in large concentrations, resulting in negative health effects such as lowered fertility and increased incidence of certain cancers. They have been found in trace amounts (parts per trillion to parts per billion) in treated wastewater, and also have been detected in water samples collected from Lake Mead.

In a new study published in the journal Environmental Pollution, DRI researchers Xuelian Bai, Ph.D., and Kumud Acharya, Ph.D., explore the potential for use of a species of freshwater green algae called Nannochloris to remove EDCs from treated wastewater.

Designed by Hong Seonghwan, Lee Hyungtaek, Lee Taekkyung, and Song Yoojin, Median AMB is a median ambulance concept that responds to traffic accidents on highways. Due to the location, there are more likely serious injuries compared to those standard roads, however, when congestion occurs, it can be difficult for ambulance to arrive on time. This concept ambulance is designed to use highway’s media strip, in this way, it will arrive quickly without the need to stop to save most crucial minute.

Median AMB rides median strip as its track, so regardless the traffic, it can reach the accident site for quick rescue task. It returns to the tollgate and transfers patient to the waiting ambulance. It’s a smart system where patients can go to the hospital quickly for further treatments.

I do think that due to the many problems of super fungus that are basically very damaging to human health I think there are other fungi that can basically stop this with like mosses and other symbiotic fungis that can basically boost the defenses of nature itself and the human populations aswell. Usually you have a super fungus because there is not a natural fungis that can shoulder the defense against malignant destruction fungus. There is always a natural defense against large scale destruction fungus that can just eat this fungi and also give food to people. But it is because the basically natural defenses against fungi that are poisonous makes it so that the super fungus are evolving too quickly. A simple basically moss that spread and be a defensive measure eating the poisonous fungi then creating a better environment.

Every year, an estimated 23,000 Americans die from antibiotic-resistant superbugs – germs that evolve so quickly, existing treatment options can’t eradicate them.

But it’s not just deadly drug-resistant bacterial infections that are spreading. We also have to worry about drug-resistant fungal infections, too.

For the association between nutrient intake and the risk of death, the researchers found:

Adequate intake of certain nutrients is associated with a reduction in all-cause mortality when the nutrient source is foods, but not supplements, according to a new study. There was no association between dietary supplement use and a lower risk of death.

In addition, excess calcium intake was linked to an increased risk of cancer death, which the researchers found was associated with supplemental doses of calcium exceeding 1,000 mg/day. The study was published on April 9 in Annals of Internal Medicine.

A new cancer “vaccine” that’s injected directly into a single tumor can trigger the immune system to attack cancer cells throughout the body, a small new study suggests.

The researchers say that the experimental therapy essentially turns tumors into “cancer vaccine factories,” where immune cells learn to recognize the cancer before seeking it out and destroying it in other parts of the body. “[We’re] seeing tumors all throughout the body melting away” after injecting just one tumor, said lead study author Dr. Joshua Brody, director of the Lymphoma Immunotherapy Program at the Icahn School of Medicine at Mount Sinai in New York.

Still, the research, published today (April 8) in the journal Nature Medicine, is very preliminary. The therapy has only been tested in 11 patients with non-Hodgkin’s lymphoma (a cancer of immune system cells), and not all of these patients responded to the treatment. But some patients did have remission for relatively long periods, and the results were promising enough that the therapy is now also being tested in patients with breast and head and neck cancers, the authors said.

Bacteria’s ability to develop antibiotic resistance is well known — but it turns out fungi are also evolving to withstand modern medicine.

Now one such fungus is cropping up in hospitals all across the globe and killing half the people who contract it within 90 days, according to an alarming story by The New York Times — raising concerns about a new global epidemic.

Great white sharks—one of the ocean’s most fearsome apex predators—thrive with toxic levels of poisons flowing in their veins, according to a new study by OCEARCH.

Researchers recently came to that conclusion after taking blood samples from 40 white sharks off South Africa, according to an April 3 report on OCEARCH.org.

The samples revealed “alarmingly high levels of poisonous heavy metals, like arsenic and mercury, in sharks’ blood,” says the report.
