New Medical Discovery
A team of scientists at the Boston Children’s Hospital have invented what is being considered one the greatest medical breakthroughs in recent years. They have designed a microparticle that can be injected into a person’s bloodstream that can quickly oxygenate their blood. This will even work if the ability to breathe has been restricted, or even cut off entirely.
This finding has the potential to save millions of lives every year. The microparticles can keep an object alive for up to 30 min after respiratory failure. This is accomplished through an injection into the patients’ veins. Once injected, the microparticles can oxygenate the blood to near normal levels. This has countless potential uses as it allows life to continue when oxygen is needed but unavailable. For medical personnel, this is just enough time to avoid risking a heart attack or permanent brain injury when oxygen is restricted or cut off to patients.
Dr. John Kheir, who first began the study, works in the Boston Children’s Hospital Department of Cardiology. He found inspiration for the drug in 2006, when he was treating a girl in the ICU who had a sever case of pneumonia. At the time, the girl didn’t have a breathing tube, when at the time she suffered from a pulmonary hemorrhage. This means her lungs had begin to fill up with blood, and she finally went into cardiac arrest. It took doctors about 25 minutes to remove enough blood from her lungs to allow her to breath. Though, the girl’s brain was severely injured due to being deprived of oxygen for that long and she eventually died.

The microparticles used are composed of oxygen gas pocketed in a layer of lipids. A Lipid is a natural molecule that can store energy and act as a part of a cell membrane, they can be made of many things such as wax, vitamins, phospholipids, and in this case fat is the lipid that stores the oxygen.
These microparticles are around two to four micrometers in length and carry about three to four times the oxygen content of our own red blood cells. In the past, researchers had a difficult time succeeding as prior tests caused gas embolism. This meant that the gas molecules would become stuck trying to squeeze through the capillaries. They corrected this issue by packaging them into small deformable particles rather ones where the structure was rigid.
Potential Future Uses
Medical: There is the obvious medical uses where the microparticles can be used to save off death from a restriction in breathing due to inflammation of the lungs, collapsed lungs, and the like. It would be good to have these injections ready in hospitals and ambulances for when the time is needed.
Military: Can you imagine a navy seals capability when they wouldn’t need to surface for air and could stay underwater for over 20 minutes? If a boat was to begin to sink, you could shoot yourself as the boat is going down to ensure you aren’t drowned in the under current of the sinking vessel. How about for toxic gases when a facemask is unavailable. The military could have a number of uses for such a medical advancement.
Private Sector: Really this can be used as a precaution for anything nautical where the potential to drown is a real danger. Deep sea rescue crews could inject themselves prior to making a rescue, underwater welders can use it in case they become stuck or air is lost to their suits. The potential use for anything water related seems extremely worthwhile.
In the end, this is an amazing medical advancement and I cant help but recall the movie the Abyss when they took the pill, their helmets filled with air, and they were told they can breathe the water. Well what if they really couldn’t “breathe” water” but since the urge to breathe is natural, that must take place… even if you’re not breathing air per se. But your body was provided with enough oxygen for a time period by taking a pill. It’s just goes to show that anything, absolutely anything that can be thought up, can potentially one day become reality. Thank you scientists, for reminding me that people and their ingenuity are nothing short of awesome.

Spanish fresco restoration botched by amateur22 August 2012 Last updated at 12:46 ET
An elderly parishioner has stunned Spanish cultural officials with an alarming and unauthorised attempt to restore a prized Jesus Christ fresco.
Ecce Homo (Behold the Man) by Elias Garcia Martinez has held pride of place in the Sanctuary of Mercy Church near Zaragoza for more than 100 years.
The woman took her brush to it after years of deterioration due to moisture.
Cultural officials said she had the best intentions and hoped it could be properly restored.Donation
The woman, in her 80s, was reportedly upset at the way the fresco had deteriorated and took it on herself to "restore" the image.
BBC Europe correspondent Christian Fraser says the delicate brush strokes of Elias Garcia Martinez have been buried under a haphazard splattering of paint.
The once-dignified portrait now resembles a crayon sketch of a very hairy monkey in an ill-fitting tunic, he says.
The woman appears to have realised she was out of her depth and contacted Juan Maria Ojeda, the city councillor in charge of cultural affairs.
Art historians are expected to meet at the church soon to discuss how to proceed.
Mr Ojeda said: "I think she had good intentions. Next week she will meet with a repairer and explain what kind of materials she used.
"If we can't fix it, we will probably cover the wall with a photo of the painting."
The fresco is not thought to be very valuable, but has a high sentimental value for local people.
Our correspondent says that to make matters worse, the local centre that works to preserve artworks had just received a donation from the painter's granddaughter which they had planned to use to restore the original fresco.

Scientists Find ‘Miracle Molecule’ In Red Wine, Blueberries
By Suzanne Monaghan and Dr. Brian McDonough
PHILADELPHIA (CBS) – There may be another health benefit drinking red wine.
Scientists report a so-called “miracle molecule” found in red wine might help improve mobility and prevent falls among older adults. The ingredient is called ‘resveratrol.’ Assistant Professor of Pharmacology at Duquesne University Jane Cavanaugh says they tested the effect on laboratory mice.
“As these animal age, they lose some of their motor coordination. Very similar as to humans do as they age. And when we gave them out the resveratrol, the older mouse has less loss of motor coordination.”
Resveratrol is also found in grapes, blueberries and other dark-skinned fruits.
“We just used blueberries in our study and actually when they eat the whole fruit it’s actually more effective than the resveratrol alone and you don’t need as much.”
A person would have to drink at least a bottle of wine compared to only a handful of fruit to get the same amount.
The finding was presented at the American Chemical Society meeting in Philadelphia on Sunday.
KYW Newsradio Medical Editor Dr. Brian McDonough says, “We already know resveratrol helps reduce inflammation of the body. It helps lower cholesterol and there have been some studies that show it reduces the risk of heart disease and certain forms of cancer.”
But, Dr. McDonough says its effects on mobility were previously unknown. “This report takes a look at balance issues in the elderly. If there was something out there that could help reduce the incidence of falls it would be critical and certainly beneficial.”
Eager to incorporate resveratol-rich ingredients in your diet? Dr. McDonough says it probably wouldn’t hurt (although he stresses moderation when drinking any alcohol).
“There’s obviously no harm in red grapes, blueberries and nuts and people who drink red wine in moderation seem to do well as well. I really believe at this point you could look at these options. Studies will be done and manufacturers are going to take a look at how they can make a magic pill of some sorts. But at this point you can do a great deal with diet.”

New family of spiders found in Oregon cave
By By JEFF BARNARD, AP Environmental Writer – 8 hours ago
GRANTS PASS, Ore. (AP) — Amateur cave explorers have found a new family of spiders in the Siskiyou Mountains of Southern Oregon, and scientists have dubbed it Trogloraptor — Latin for cave robber — for their fearsome front claws.
The spelunkers sent specimens to the California Academy of Sciences in San Francisco, which has the West Coast's largest collection of spiders. Entomologists there say the spider — reddish brown and the size of a half dollar — evolved so distinctly that it requires its own taxonomic family — the first new spider family found in North America since the 1870s.
"It took us a long time to figure out what it wasn't," said Charles Griswold, curator of arachnids at the academy. "Even longer to figure out what it is. We used anatomy. We used DNA to understand its evolutionary place. Then we consulted other experts all over the world about what this was. They all concurred with our opinion that this was something completely new to science."
"It's a good example of how science works — professional and citizen scientists share information," he added.
The discovery is described in the Friday online edition of the journal ZooKeys.
Jonathan Coddington, curator of arachnids at the Smithsonian Institution and associate director for science at the National Museum of Natural History, agreed that the spiders represent a family never seen before.
"This is really a distinct event," he said. "To walk out in the woods and find an example of an ancient lineage that no one has ever seen before is special."
Norman I. Platnick, curator emeritus of spiders at the American Museum of Natural History, said the discovery was as exciting to spider scientists as the discovery of a new dinosaur to paleontologists.
"Because it belongs to one of the more primitive groups of true spiders, it has the potential to change many of our current ideas about the early evolution of spiders," he said. "But it is better than a fossil, because we can study the entire organism, along with its behavior and physiology, not just those aspects that happen to have been fossilized."
Coddington said caves tend to keep primitive species from evolving, because they are sheltered from climatic and other changes.
"Once you figure out a lifestyle, you can just do it for millions of years," he said.
The Oregon spider's species name — marchingtoni — honors Deschutes County sheriff's Deputy Neil Marchington, who was on the first Western Cave Conservancy expedition in 2010 to inventory the critters in a cave on private land outside Grants Pass. A year later he led academy scientists to the site to collect live specimens.
"A lot of times, caves are very unique ecosystems, and what we find in there can be very special," said Marchington from the jail in Bend where he works. "At other times, they can be completely normal."
He said about a dozen of them collected bugs from the walls and ceiling of the cave and put them in vials of preservative, then sent them down to the academy.
"We don't know exactly how they work yet," Griswold said of the spiders. "We've seen these spiders alive. But we haven't seen them eat anything yet. They are very shy.
"They make a little web, but hang under this web. They hang some of their legs out in space. This is all in the dark in a cave. We think the legs are stretched out waiting for something to come by, like a fly, and when it hits the legs, the claws may just snap shut."
Though scientists built a small artificial cave for the spiders in their lab, the spiders would not eat any of the insects, and died.
Griswold said new families of spiders are described around the world every 20 years or so, but the last ones to be found in North America date to the 1870s, when two families of desert spiders were found in Southern California, Arizona and Mexico, and another was found in the Appalachian Mountains.
After the spiders were found in the Oregon cave, scientists from San Diego State University went looking in the redwoods of Northern California, and found a spider in the same family, but a new species, living in underground cavities beneath boulders and logs, Griswold said.
