One out of every ten newborn infants displays a weird quirk of the human body called “harlequin sign.” It makes babies spontaneously turn parti-colored, especially when their tiny bodies heat up. »
Electrodes currently used to directly monitor the brain are made from solid materials that can damage the tissue they’re inserted into. But a new type of flexible electrode may change that. »
The 2015 Nobel Prize for Physiology or Medicine just went to three scientists who found parasite-killing chemicals that are now important tools for fighting human diseases. But the chemicals in question weren’t created in a lab: one is produced naturally by a bacterium, the other by a plant used in a traditional… »
The first Nobel Prize of 2015 has been awarded jointly to three scientists for their groundbreaking work in developing therapies that fight infections caused by malaria and roundworm parasites. »
If you’ve been debating whether to get a flu shot, you should watch this beautifully terrifying animation of a virus taking over a cell and sending millions of its progeny off to spread the infection. »
Understanding how the brain works is important, but going hands-on to test drugs or other treatments can be difficult. Which is why a team from Brown University has created these miniature ball-shaped brains for use in the lab.
In Africa, only four countries record more than 75% of their births and deaths. This creates an unequal system and impacts on how governments plan for these citizens. »
As sperm swim they transform chemical energy into motion, the way a car’s engine uses gas to propel you down the road. Like that engine, the process is complicated—if just one part stops working, the whole system can grind to a halt. This idea might lead to a contraceptive for men that’s reversible. »
When you go to the doctor, there’s a medical code that determines how your treatment gets billed. Getting treated for urban rabies? Well, that’s distinct from woods-based sylvatic rabies, and your invoice will reflect that. Until today, the system in the US was the same one we used in the 1970s. But there’s a new… »
Security researchers claim that at least 68,000 medical systems — like MRI scanners and infusion systems — from a “large, unnamed US health group” are accessible online for hackers to attack. »
It’s long been thought that anti-inflammatory painkillers need to be taken at the same time as food to protect the stomach. But a handbook for doctors has recently moved away from this advice. »
3D printing is changing the way we build things—but what if the end-product can’t support its own weight until it’s finished? Scientists have developed a way to overcome that problem, by surrounding the whole thing with gel.
It may look like a sci-fi space scene or a Fear and Loathing out-take, but this image, which shows a a zebrafish larva infected with meningitis, could help researchers develop new treatments for the disease. »
The Ig Nobel awards ceremony is a marvelous spectacle encrusted with tradition. But if you really want to know how the winners did their work and why, you need to go to the Ig informal lectures, held at MIT the Saturday after the awards. »
All the cells in our bodies are programmed to die. As they get older, our cells accumulate toxic molecules that make them sick. In response, they eventually break down and die, clearing the way for new, healthy cells to grow. This “programmed cell death” is a natural and essential part of our wellbeing. Every day,… »
A team of scientists has successfully re-routed the signals from a paraplegic man’s brain to his knees, allowing him to walk using his own legs for the first time in five years.
