A biologist is studying how poison gas can be used to induce a state of "suspended animation" in small animals. Someday, it might even work on people. The idea is that if someone has suffered a critical injury, the technique could be used to delay death so that emergency care could be administered. Roth, a MacArthur "Genius," has had some success with mice. He used hydrogen sulfide to dramatically drop the rodents' breathing rate and reversed the process after six hours. It hasn't scaled up to larger animals so far, but he's working on it. Meanwhile, other techniques to slow metabolism for similar purposes are also showing promising. From CNN:
"You get a state of suspended animation and the creatures do not pass away, and that's the basis of what we see as an alternative way to think about critical care medicine," Roth says. "What you want to do is to have the patient's time slowed down, while everyone around them [like doctors] move at what we would call real time."

If the patient's time -- the process of your death -- were slowed down, doctors would have more time to fix you. In medicine, time is key. An analogy is the history of open heart surgery. For years, surgeons had the technical tools to make simple repairs on the heart, but they couldn't help patients until the development of the heart-lung machine made it possible to preserve the body for more than a few minutes without a heartbeat...
Other researchers are exploring different approaches to tweak metabolism in a critical care setting. A group in Minnesota is developing a drug based on chemicals found in hibernating squirrels. Dr. Philip Bickler, an anesthesiologist at the University of San Francisco Hospital, is also studying animals, including whales and dolphins -- mammals like us, except that they can hold their breath for two hours underwater even during vigorous activity. Bickler says, "There's a lot of potential there. It hasn't been studied in extreme detail, but there may be new ways to protect human tissue from injury.
The EVATAR is a working model of a reproductive system made from a mouse ovary and bits of a human uterus, cervix, vagina, fallopian tubes, and liver. Developed by Northwestern University researcher Teresa Woodruff and her colleagues, the EVATAR is intended to help better test the effects of medicines and toxins on women. And now […]
Texas State University’s Body Farm (AKA Forensic Anthropology Center at Texas State University or FACTS) is a 45-year-old facility where the corpses of medical body donors are left to decompose so that researchers can observe the rate at which human remains are consumed by the elements, scavengers and microbes, allowing them to accurately date the […]
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Maybe it’s entirely because of podcast ads, but drag-and-drop tools like Squarespace have gotten immensely popular in recent years. While it’s definitely a great tool for any non-coders who want to get a small website up and running quickly, managing content with a primarily visual interface can become a pain once you have more than […]
When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else. Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]
