Katherine Powell (University of Akron) Ghana - Health Care Program (9 days): Given I had never traveled outside of the United States, traveling to Ghana proved to be a major culture shock in more ways than one. The heat was incredible, the people were unbelievable. Everyone there exuded a relaxed nature, and everyone on my team agrees that the Ghanaians exhibited a level of generous hospitality unmatched by anyone anywhere. Traveling as a student, I was uncertain as to what sort of cases we would be seeing, and what type of circumstances we would find ourselves facing. However, through the guidance of Edem and his family, that skepticism quickly fell away as we dove into learning about the culture, meeting the locals, and providing care and education to those who would not otherwise have had the chance to learn about health and their bodies. As a students, I felt empowered to then return the education I was receiving overseas to the beautiful people of Ghana. We encountered many obstacles, such as limited supplies, and spiritual traditions that greatly minimized our ability to apply the necessary care. We were all able to take home a different aspect of learning, teaching and culture by the end of the week. My only regret was that this trip was in fact so short in length. Should there be a next time, I would aim for at least two weeks. Between the hospitality of Edem and his family, the helpfulness of the ABV staff in the States, and my team, I don’t see why we wouldn’t return in the near future.
Women who consume 1,000 mg of calcium a day—regardless if consumed in food or supplements—may live longer, new research suggests.
Calcium, an essential nutrient for bone health, is commonly found in dairy products as well as vitamins. Despite calcium’s health benefits, past studies have linked calcium supplements to heart disease risk.
The researchers analyzed data from the large-scale Canadian Multicentre Osteoporosis Study (CaMos) seeking to determine whether calcium and vitamin D intake were associated with overall increased risk of death. The research is published in the Journal of Clinical Endocrinology & Metabolism.
Homes and buildings chilled without air conditioners. Car interiors that don't heat up in the summer sun. Tapping the frigid expanses of outer space to cool the planet. Science fiction, you say? Well, maybe not any more. A team of researchers at Stanford has designed an entirely new form of cooling structure that cools even when the sun is shining. Such a structure could vastly improve the daylight cooling of buildings, cars and other structures by reflecting sunlight back into the chilly vacuum of space.
Learn about what the number 400 means for our future. On May 9th, for the first time ever, the world's most important CO2 monitoring station recorded daily CO2 concentrations above 400 parts per million -- the highest levels found on earth in over 5 million years.Already we're seeing the deadly effects of climate change in the form of rising seas, wildfires and extreme weather of all kinds, and passing 400 PPM is an ominous sign of what might come next.The safe level of carbon dioxide in the atmostphere is 350 parts per million, but the only way to get there is to immediately transition the global economy away from fossil fuels and into into renewable energy, energy efficiency, and sustainable farming practices in all sectors (agriculture, transport, manufacturing, etc.).
While the level fluctuates seasonally and varies across different latitudes, this is yet another sign that our dependence on fossil fuels is out of control.
According to the National Oceanic and Atmospheric Administration’s (NOAA) Fisheries Office of Protected Resources, the Kemp’s Ridley, which are distributed largely throughout the Gulf of Mexico and U.S. Atlantic seaboard, has experienced a dramatic decrease in nesting sizes since 1947 from an estimated 42,000 to just 200 annually between 1978 and 1991.
However, this number has increased steadily over the past decade peaking in 2009 at just over 20,000.
The world’s largest concentrated solar power plant opened in March in the middle of Abu Dhabi’s western region, amid the country’s giant oil fields.
The $600 million plant’s hundreds of mirrors direct sunlight towards towers full of water. These are heated to drive steam turbines that provide enough electricity for thousands of homes.
In a country whose vast wealth is generated by oil, adopting a new technology that produces only 100 megawatts of power — about a tenth the amount of a large coal-fired plant — may seem a mere token, but it is part of a much larger industrial strategy for the region.
Serious money and political clout in Europe, the Middle East, and North Africa is aimed at building hundreds of similar plants. The potential is so great that all the electricity requirements of these desert countries — and a good slice of Europe’s — could be met by 2050.
More than half of Panama's forests are on land belonging to indigenous people, who say a key UN policy designed to safeguard the forests is in fact over-riding their interests.
REDD – Reducing Emissions from Deforestation and forest Degradation – is designed to slow climate change by preventing the destruction of the world’s most vulnerable forests. It is a key part of the UN’s attempts to tackle a warming climate, and failure in Panama will have impacts much further afield.
y the National Coordinating Body of Indigenous Peoples in Panama (Coonapip), will test a provision of the 2007 UN Declaration on the Rights of Indigenous Peoples, which says they have the right to refuse projects and investments which affect their natural resources.
“When it comes to the forests of Panama, we are not mere stakeholders to be consulted”, said Betanio Chiquidama, president of Coonapip and cacique (chief) of a reserve that is home to more than 33,000 people in the east of the country.
“More than half the country’s forests are on the lands of indigenous people. How can an effective plan to save these forests be negotiated if the indigenous leaders are not at the table?
“The pressure on the forests has never been greater – for food, fuel, fibre and mineral exploration. But we also know that there are other lands that could be used for these purposes; the answer is not to kill our forests.”
Water found in a deep, isolated reservoir in Timmins, Ont., has been trapped there for 1.5 billion to 2.64 billion years — since around the time the first multicellular life arose on the planet — Canadian and British scientists say.
The water pouring out of boreholes 2.4 kilometres below the surface in the northern Ontario copper and zinc mine is older than any other free-flowing water ever discovered. It is rich in dissolved gases such as hydrogen and methane that could theoretically provide support for microbial life.
"What we can be sure of is that we have identified a way in which planets can create and preserve an environment friendly to microbial life for billions of years," said a statement from Greg Holland, the Lancaster University geochemist who is the lead author of the study.
His Canadian co-authors included Barbara Sherwood Lollar and Georges Lacrampe-Couloume at the University of Toronto; Greg Slater at McMaster University in Hamilton; and Long Li, who is currently an assistant professor at the University of Alberta, but worked on the project while at the University of Toronto.
Some Canadian members of the team are currently testing the water to see if it contains microbial life — if they exist, those microbes may have been isolated from the sun and the Earth's surface for billions of years and may reveal how microbes evolve in isolation.
Microbes that have been isolated for tens of millions of years have been found in water with similar chemistry at even slightly deeper depths below the surface in a South African gold mine, using hydrogen gas as an energy source, the researchers noted.
The researchers estimated how old the water was based on an analysis of the xenon gas dissolved in it. Like many other elements, xenon comes in forms with different masses, known as isotopes. The water in the Timmins mine contained an unusually high level of lighter isotopes of xenon that are thought to have come from the Earth's atmosphere at the time it became trapped.
The Water Capacitor turns water into a hydrogen-oxygen gas mixture that can then be used as a fuel for heating, cooking, welding, fixed generators, and powering internal combustion engines.
The Water Capacitor will then be incorporated into a kit offered from True Green solutions to individual consumers.
The Proof of Principle was demonstrated in Stanley Meyer's original water splitting devices as hydrogen fuel was extracted from water with his Electrical Polarization invention that was documented in his patents through the mode of operability.
Edward Mitchell has already built a working prototype and is now refining the design to be incorporated into a complete Exciter Array (Water Fuel Capacitor(C)) Kit.
A lot can change in 28 years, and Google has put together a very graphic demonstration of just how much can happen geographically with a new effort that combines global, annual Landsat satellite image composites with its Google Earth Engine software.
Near the moonscape summit of the Mauna Loa volcano in Hawaii, an infrared analyser will soon make history. Sometime in the next month, it is expected to record a daily concentration of carbon dioxide in the atmosphere of more than 400 parts per million (p.p.m.), a value not reached at this key surveillance point for a few million years.
There will be no balloons or noisemakers to celebrate the event.
Researchers who monitor greenhouse gases will regard it more as a disturbing marker of humanity’s power to alter the chemistry of the atmosphere and by extension, the climate of the planet. At 400 p.p.m., nations will have a difficult time keeping global warming in check, says Corinne Le Quéré, a climate researcher at the University of East Anglia in Norwich, UK, who says that the impact “is getting very dangerously close to reaching the 2 °C target that governments around the world have pledged not to exceed”.
It will be a while, perhaps a few years, before the global CO2 concentration averaged over an entire year, passes 400 p.p.m.. But topping that value at Mauna Loa is significant because researchers have been monitoring the gas there since 1958, longer than any other spot. “It’s a time to take stock of where we are and where we’re going,” says Ralph Keeling, a geochemist at the Scripps Institution of Oceanography in La Jolla, California, who oversees that centre’s CO2 monitoring efforts on Mauna Loa. That gas record, known as the Keeling curve, was started by his father, Charles Keeling.
Researchers at the Harvard Stem Cell Institute have discovered a hormone that holds promise for a dramatically more effective treatment of type 2 diabetes, a metabolic illness afflicting an estimated 26 million Americans. It could eventually mean that instead of taking insulin injections three times a day, you might take an injection of this hormone once a week or once a month, or in the best case maybe even once a year,” said Doug Melton (right). Melton and postdoctoral fellow Peng Yi discovered the hormone betatrophin, which has the potential to improve diabetes treatment.
Researchers at the Harvard Stem Cell Institute (HSCI) have discovered a hormone that holds promise for a dramatically more effective treatment of type 2 diabetes, a metabolic illness afflicting an estimated 26 million Americans. The researchers believe that the hormone might also have a role in treating type 1, or juvenile, diabetes.
The hormone, called betatrophin, causes mice to produce insulin-secreting pancreatic beta cells at up to 30 times the normal rate. The new beta cells only produce insulin when called for by the body, offering the potential for the natural regulation of insulin and a great reduction in the complications associated with diabetes, the leading medical cause of amputations and non-genetic loss of vision.
The researchers who discovered betatrophin, HSCI co-director Doug Meltonand postdoctoral fellow Peng Yi, caution that much work remains to be done before it could be used as a treatment in humans. But the results of their work, which was supported in large part by a federal research grant, already have attracted the attention of drug manufacturers.
