A University of Calgary research team developed a new method for extracting carbon dioxide (CO₂) directly from the air — a fundamental shift in carbon capture technology enabling capture of the most common greenhouse gas from so-called diffuse sources like aircraft, trucks and automobiles that represent half of the greenhouse gases emitted globally.

Professor David Keith, Director of University of Calgary’s (UofC) Institute for Sustainable Energy, Environment and Economy (ISEEE) and a team of researchers from UofC’s Energy and Environmental Systems Group built and operated a prototype system this summer producing results that compared favourably with commercial carbon capture systems. Two ‘provisional’ patents have been filed on the technology but Keith warns there are still “many pitfalls along the path to commercialization.”

Using a process adapted from the pulp-and-paper industry that halves the cost of CO₂ air capture in their custom-built tower, Professor Keith and his team captured the equivalent of about 20 tonnes per year of CO₂ (approximately equal to the yearly output of one person in North America) directly from the air with less than 100 kilowatt-hours of electricity per tonne of carbon dioxide on a single square metre of scrubbing material.

“This means that if you used electricity from a coal-fired power plant, for every unit of electricity you used to operate the capture machine, you’d be capturing 10 times as much CO₂ as the power plant emitted making that much electricity,” explains Professor Keith.

A report co-authored by Keith in the American Chemical Society’s journal Environmental Science & Technology explains “nearly all current research on carbon capture and storage (CCS) focuses on capturing CO₂ from large, stationary sources such as power plants. Such plans usually entail separating CO₂ from flue gas, compressing it, and transporting it via pipeline to be [stored] underground.”

Using CO₂ air capture technology, “a company could, in principle, contract with an oil sands plant near Fort McMurray to remove CO₂ from the air and could build its air capture plant wherever it’s cheapest — China, for example — and the same amount of CO₂ would be removed,” says Professor Keith in a UofC press release.

“While it’s important to get started doing things we know how to do, like wind power, nuclear power, and ‘regular’ carbon capture and storage,” Professor Keith continues, “it’s also vital to start thinking about radical new ideas and approaches to solving this problem.”

ISEEE’s Executive Director David Layzell points out that “energy-efficient and cost-effective air capture could play a valuable role in complementing other approaches for reducing emissions from the transportation sector, such as biofuels or electric vehicles.”

Frieda Birnbaum, aged 60, gave birth to two sons on May 22, at 12:44 pm at Hackensack University Medical Center in Trenton, New Jersey. Both babies were delivered by Caesarean section, and each weighed 4 pounds, 11 ounces and are doing well.

“The mom is in recovery, and she and the babies are doing really well,” said Nancy Radwin a spokeswoman for the medical center.

Doctors believe Birnbaum may be the oldest woman in the United States to give birth to twins. Birnbaum has been married to her husband Ken for 38 years, and underwent in-vitro fertilization last year in Cape Town, South Africa. The couple already had three children, a daughter, 29 and two sons, 6 and 33.

“This is so wonderful, I feel so relaxed. It has been a great experience. I don’t feel like I’m 60. I don’t know what 60 is meant to be,” said Birnbaum as quoted by Newsday, who quotes FOX News.

Women giving birth this late in age, says Radwin, face high risks when they become pregnant.

“There were no guidelines of what to do and what to look for in a pregnancy at the age to 60. Can the heart or the kidneys withstand the pregnancy? It becomes a little risky to take care of this pregnancy,” added Radwin.

One year ago, a now 60 year-old woman also from New Jersey named Lauren Cohen gave birth to twins. Birnbaum and Cohen became friends after Birnbaum contacted Cohen about her giving birth.

Currently, Maria del Carmen Bousada Lara, who lives in Spain, is the oldest woman in the world to give birth to twins. On December 29, 2006, she gave birth to two boys. She was 67 at the time.

Researchers say that new, ten million-year-old fossils found in Ethiopia, prove that the theory that humans may have evolved from a species of great apes eight million years ago, may not be true, but that humans may have split from apes as long as 10.5 million years ago.

At least nine fossilized teeth, one canine tooth and eight molars, of a previously unknown species of apes found in Africa were discovered by a team of researchers from Ethiopia and Japan who then compared the 3-D make up of the teeth to other fossils that date back as far as 8 million years and found that the fossils are likely a “direct ancestor” of apes currently living in Africa and that the new ape fossils were that of a species of gorilla who ate mostly plants high in fiber.

Current fossils and research say that the evolutionary split from apes to humans occurred at least eight million years ago. The new fossils say that the split may have happened as long as 10.5 million years ago.

“Based on this fossil, that means the split is much earlier than has been anticipated by the molecular evidence. That means everything has to be put back,” said researcher at the Rift Valley Research Service in Ethiopia and a co-author of the study, Berhane Asfaw.

Despite the finds, other researchers are not convinced that the findings are correct.

“It is stretching the evidence to base a time scale for the evolution of the great apes on this new fossil. These structures appear on at least three independent lineages of apes, including gorillas, and they could relate to a dietary shift rather than indicating a new genetic trait,” said a Professor at the London Natural History Museum in the United Kingdom, Peter Andrews who also added, “but the fossil evidence for the evolution of our closest living relatives, the great apes, is almost non-existent.

Researchers have named the newly discovered species Cororapithecus abyssinicus whose remains were found in the Afar Region of Ethiopia, the same place where the remains of Lucy were discovered in 1974.

Diamond Brownridge, a 5-year old girl from Chicago, Illinois, has died after a visit to the dentist. Children’s Memorial Hospital officials say that the girl was rushed to the hospital when she never woke up after being sedated for a dental procedure. She had been in a coma, on life support, since being admitted to the hospital early in the weekend.

“She passed very peacefully and beautifully,” said the hospital in a statement that the family issued.

Ommettress Travis, the mother of the girl, was asked not to remain inside the room while dentists were operating on the girl to repair two cavities and to have at least two caps replaced. Travis says after thirty minutes she was asked to come back in and found Brownridge not breathing, in the dentist chair.

Hicham Riba, a specialist and professional in anesthesia, who was also licensed, was the dentist in charge of the procedure.

“My family and I are so sad. May God bless Diamond and her family. Every time you have a tragedy like this, you pray more. I don’t think I will ever go back to a normal life after an experience like this,” Riba said in a statement on Wednesday, September 28.

According to the family, the girl had been given at least a triple dose of medicine that sedated her. Those drugs include: nitrous oxide gas, a single dose of an “oral agent” and an IV.

A judge has ordered that all equipment and materials used during the operation be protected and examined. The girl’s medical records have also been ordered to be examined.

There is no word on whether or not any charges will be filed against Riba or any of the dentist’s staff.

Chinese authorities say they are preparing to launch a crackdown on melamine-laced milk after the scandal over tainted products, which made hundreds of thousands of children ill two years ago and damaged China’s brand reputation overseas, resurfaced.

China has dispatched inspectors to sixteen provinces to urge local governments to thoroughly investigate cases concerning food safety.

The decision comes after milk products tainted with the industrial chemical melamine were removed from sale in Shanghai and the provinces of Shaanxi, Shandong, Liaoning and Hebei, the state-run Xinhua News Agency said.
