New Medical Discovery A team of scientists at the Boston Children’s Hospital have invented what is being considered one the greatest medical breakthroughs.
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.

Nature is a wondrous beauty as the ice age flower blooms after 32000 years of being non-existent.
According to Discover Magazine, Russian scientists announced that they had unearthed the fruit and brought tissue from it back to life. after the seeds were buried over 32000 years ago. The discovery was made in northwestern Siberia, where the winter team of Russian scientists found the seeds of the flower and regrew it. The plant breaks the previously held record of the oldest tissue to give life to healthy plants, which was previously held by the Israeli date palm seed.
In 1995, researchers studying and working with ancient soil composition in an exposed Siberian riverbank found 70 fossilized Ice Age squirrel burrows, some of which stored up to 800,000 seeds and fruits. With the help of the permafrost, the narrow-leafed campion plant tissue was preserved well enough for the team at the Russian Academy of Sciences to culture the cells to see if they would grow. The team, led by team leader Svetlana Yashina, were successful and re-created Siberian conditions in the lab and watched as the refrigerated tissue sprouted buds that developed into 36 flowering plants within weeks.
Tardigrades (commonly known as waterbears or moss piglets) are small, water-dwelling, segmented animals with eight legs. They form the phylum Tardigrada, part of the superphylum Ecdysozoa.
Tardigrades were first described in 1773 by Johann August Ephraim Goeze, who called them kleiner Wasserbär, meaning 'little water bear' in German. The name Tardigrada means "slow walker" and was given by Lazzaro Spallanzani in 1777. The name water bear comes from the way they walk, reminiscent of a bear's gait. The biggest adults may reach a body length of 1.5 millimetres (0.059 in), the smallest below 0.1 mm. Freshly hatched tardigrades may be smaller than 0.05 mm.
Some 1,150 species of tardigrades have been described. Tardigrades occur throughout the world, from the Himalayas (above 6,000 metres (20,000 ft)), to the deep sea (below 4,000 metres (13,000 ft)) and from the polar regions to the equator.
The most convenient place to find tardigrades is on lichens and mosses. Other environments are dunes, beaches, soil, and marine or freshwater sediments, where they may occur quite frequently (up to 25,000 animals per litre). Tardigrades often can be found by soaking a piece of moss in spring water.
Tardigrades are able to survive in extreme environments that would kill almost any other animal. Some can survive temperatures of close to absolute zero, or 0 Kelvins (−273 °C (−459 °F)), temperatures as high as 151 °C (304 °F), 1,000 times more radiation than other animals, and almost a decade without water. Since 2007, tardigrades have also returned alive from studies in which they have been exposed to the vacuum of outer space for a few days in low Earth orbit.
New, colorful monkey species discovered in Africa rain forest
A shy, brightly colored monkey species has been found living in the lush rain forests at the heart of the Democratic Republic of Congo, a find that utterly surprised the researchers who came upon it.
"When I first saw it, I immediately knew it was something new and different — I just didn't know how significant it was," said John Hart, a veteran Congo researcher who is scientific director for the Lukuru Wildlife Research Foundation, based in Kinshasa.
In fact, the find was something of a happy accident. Hart first spied the suspect monkey in 2007 while sifting through photographs brought back from a recently concluded field expedition to a remote region of the central Democratic Republic of Congo (formerly known as Zaire).
The image that caught his eye hadn't been taken in the field. It was snapped in a village, and showed a young girl named Georgette with a tiny monkey that had taken a shine to the 13-year-old. [See Georgette and the monkey.]
Strange, black objects seen from 200 miles above the surface of Mars are generating interest and speculation that the unidentified objects could be anything from geysers to sunbathing colonies of microorganisms.
NPR compares several photos of the objects, including one taken by the Mars Reconnaissance Orbiter on Jan. 27, which appears to show, "little black flecks dotting the ridges, mostly on the sunny side, like sunbathing spiders sitting in rows."
The objects were first spotted in 1998. Interestingly, they appear when the surface of Mars begins to warm, appearing in the same location most of the time. And then, when the Martian winter approaches, they disappear with the same precise regularity. The images have been brought into greater detail by Michael Benson, in his book "Planetfall: New Solar System Visions."
Most scientists, including teams from the U.S. Geological Survey, from Hungary, from the European Space Agency all have their own theories but the leading explanation is that the objects are geysers of CO2 exploding from underneath the planet's surface.
"If you were there, you'd be standing on a slab of carbon dioxide ice," Phil Christensen of Arizona State University told NPR. "All around you, roaring jets of carbon dioxide gas are throwing sand and dust a couple hundred feet into the air. The ground below would be rumbling. You'd feel it in your spaceboots."
And while the geyser theory is the most popular explanation, it has yet to be factually verified.
In the meantime, there are some interesting alternative theories, including one from a group of Hungarian scientists, who have speculated that the objects are actually colonies of photosynthetic Martian microorganisms who emerge each year to sunbathe in the warm weather.
