Book a flight on 'Air Algae?'

(Press-News.org) When the smell of french fries wafts through the airplane cabin, is it from that guy in 24D scarfing down a fast-food meal — or the jet engines? That question certainly could be food-for-thought for imaginative passengers, as airline companies develop a bigger appetite for the fuels described in the current edition of Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, the world's largest scientific society.
In the article, C&EN Senior Business Editor Melody M. Bomgardner explains that with successful test flights completed, airlines are ready and eager to fuel up with biobased jet fuel. That's fuel made from waste cooking oil from fast-food and other restaurants, waste fat, biomass and even algae — the stuff of "pond scum." Biobased fuels are blended into conventional Jet A-1 fuel. Airlines are interested partly because of rising costs for petroleum-based jet fuel.
Bomgardner notes that even though test flights, like a recent United Airlines flight from Houston to Chicago on a 40/60 mixture of bio- and conventional fuel, were a success, a lack of suppliers is making it harder for biobased jet fuels to get off the ground. One major barrier: a shortage of feedstocks like algae oil, waste cooking oil and fuel crops, which makes green jet fuels more expensive. Both the airlines and the biofuel producers are hopeful, however, that support from the private sector and the government will allow these green fuels to fly soon.

Building a terrestrial planet requires raw materials that weren't available in the early history of the universe. The Big Bang filled space with hydrogen and helium. Chemical elements like silicon and oxygen - key components of rocks - had to be cooked up over time by stars. But how long did that take? How many of such heavy elements do you need to form planets?
Previous studies have shown that Jupiter-sized gas giants tend to form around stars containing more heavy elements than the Sun. However, new research by a team of astronomers found that planets smaller than Neptune ...

Reintegrating into civilian society after a long prison term can be difficult for anyone. Finding a place to live and a way to support yourself is challenging, especially for people who don't have a strong network of family and friends to help them out.
The process can be even more troubling for individuals convicted of violent sex crimes and other offenses carrying significant social stigma. Too often, these people are rejected by their communities, even though they are legally authorized to be released from prison.
One such case is currently playing out in the California ...

(Boston) - Socioeconomic status across one's lifetime is related to weight gain and risk of obesity in African American women, according to a new study led by researchers from the Slone Epidemiology Center at Boston University. These findings currently appear online in the journal Ethnicity & Disease.
The researchers followed 23,601 African American women under the age of 55 from 1995 to 2009. These women were participants in the Black Women's Health Study, a follow-up study of the health of African Americans conducted by the Slone Epidemiology Center. The women provided ...

According to the Institute of Medicine, preventable medical errors cause almost 100,000 American deaths every year. If these deaths were included in CDC statistics, medical mistakes would be the sixth leading cause of death. Hundreds of thousands more patients live after suffering from medical negligence, but face serious and long-term injuries.
While these statistics are alarming, forgoing medical care entirely is simply not an option. So what are you to do about medical errors? As a patient, there are several measures you can take to reduce the risk, as well as after-the-fact ...

Since 1990, annual maternal deaths have declined by almost one half and the deaths of young children have declined from 12 million to 7.6 million in 2010.
Some of the world's poorest countries have achieved spectacular progress in reducing child deaths. Rates of child mortality in many African countries have been dropping twice as fast in recent years as during the 1990s. In Botswana, Egypt, Liberia, Madagascar, Malawi, Rwanda and the United Republic of Tanzania, the rate of decline was on average 5 percent or more a year between 2000 and 2010.
Similar progress has been ...

Increasingly, sex offenders are being stripped of even the slightest semblance of privacy rights. But, in Washington State, the school remains one of the last bastions of discretion for minors convicted of a sex offense.
Schools Are Not Sheriff's Departments (But Some Would Like To Change That)
Washington law prevents schools from disseminating a student's criminal history to parents, the public or other students. For juvenile sex crimes that result in required registration as a sex offender, school administrators are informed -- but they may only share this information ...

Actress Sharon Stone, best known for her roles in "Basic Instinct" and "Casino" is being sued by her former live-in nanny Erlinda T. Elemen for wrongful termination, harassment and failure to prevent harassment. In a complaint filed in Los Angeles County Superior Court, Elemen alleges Stone terminated her for accepting overtime pay, and repeatedly making comments during the course of her employment that equated being Filipino with being stupid. Elemen also said the actress criticized her accent and told her not to speak in front of Stone's children so ...

A national research collaboration of senior researchers, including a researcher from Moffitt Cancer Center, has found that 20 to 25 percent of "heavily pre-treated" patients with a variety of cancers who enrolled in a clinical trial had "objective and durable" responses to a treatment with BMS-936558, an antibody that specifically blocks programmed cell death 1 (PD-1). PD-1 is a key immune "checkpoint" receptor expressed by activated immune cells (T-cells) and is involved in the suppression of immunity.
The clinical trial, designed to assess the anti-tumor activity and ...

An Indiana University team of researchers has conducted the most in-depth and diverse genetic analysis of the defense systems that trillions of micro-organisms in the human body use to fend off viruses. The work is among a collection of 16 research papers released today by the Human Microbiome Project Consortium, a National Institutes of Health-led effort to map the normal microbial make-up of healthy humans.
Led by IU Bloomington assistant professor of informatics and computing Yuzhen Ye, the team of bioinformaticists and biologists reconstructed arrays of clusters of ...

A new report published by the AFL-CIO has determined that workplace fatalities are on the rise, despite the troubled economy in which work hours have decreased and unemployment is higher than usual. The findings should inspire review of workplace hazards and every employer's responsibility to provide a safe workplace for employees.
"Death on the Job" Findings
The AFL-CIO's report "Death on the Job" found that 13 workers were killed on the job every day in 2010, totaling 4,690 deaths nationwide. This workplace accident statistic does not include ...
