The aviation industry is a major source of greenhouse gas emissions. In 2011 aviation contributed around 3% of Australia’s emissions. Despite improvements in efficiency, global aviation emissions are expected to grow 70% by 2020 from 2005. While the industry is seeking new renewable fuel sources, growing biofuels takes up valuable land and water that could be otherwise used to grow food.
But what if you could grow biofuels on land nobody wants, using just seawater and sunlight, and produce food at the same time?-->
Honest behavior is much like sticking to a diet - you have to be ready for temptation and consider the long-term consequences.
A recent paper says it is the first study to test how the two separate factors of identifying an ethical conflict and preemptively exercising self-control interact in shaping ethical decision-making.
In a series of experiments that included common ethical dilemmas, such as calling in sick to work and negotiating a home sale, the researchers found that two factors together promoted ethical behavior: Participants who identified a potential ethical dilemma as connected to other similar incidents and who also anticipated the temptation to act unethically were more likely to behave honestly than participants who did not.
Women aged 50-69 years who attend mammography screening reduce their risk of dying from breast cancer by 40 percent compared to women who are not screened - according to a major international review of the latest evidence on breast cancer screening. Overall, women who are invited to attend mammography screening have a 23 percent risk reduction in breast cancer death (owing to some attending and some not), compared with women not invited by routine screening programs.
In the UK, this relative risk translates to around eight deaths prevented per 1,000 women regularly attending screening, and five deaths prevented per 1,000 women invited to screening.
Cancer has overtaken cardiovascular disease, which includes heart disease and stroke, as the UK's No 1 killer--but only among men, reveals research published online in the journal Heart.
Cardiovascular disease is still the most common cause of death among women, and kills more young women than breast cancer, the figures show.
The researchers used the latest nationally available data (2012-13) for each of the four UK countries and the Cardiovascular Disease Statistics 2014 report compiled for the British Heart Foundation (BHF) to quantify the prevalence of cardiovascular disease, and find out how it's treated, how much it costs, and how many deaths it causes.
The answer is a combination of an amazing new telescope, a very smart student and an unexpected fusion of two areas of science.-->
The public has a bit of a cultural schism about elections. Everyone says they want more diversity of candidates but an actual primary race is a sign of weakness. In the United States of America, Democrats are trumpeting the fact that they picked their candidate for 2016 back in 2013 and ridiculing Republicans because they have a dozen contenders. And we are told that if polls are too accurate, people will not bother to vote, but if they are not accurately predicting the winner of an election that has not occurred, it is a failure.
Though women are the majority in the life sciences and men might need outreach programs to counteract potential bias against them in the social sciences, in math-intensive fields like physics women still lag.
Sociologists believe that it may be due to misperception; that you either have math ability or you don't. Counter that misperception and you the problem is solved.
Many aquatic species have a reputation for negligent parenting. Having cast their gametes to the currents, they abandon their offspring to their fate. However, hands-on parenting is taken to a whole new dimension in the Syngnathidae fish family.
Instead of leaving the responsibility to the females, seahorse and pipefish males take the pledge to care for their young even before the eggs are fertilized. The females depart soon after placing their eggs directly into the male's brood pouch, leaving the soon-to-be fathers to incubate the developing embryos.
Until now, de novo genetic mutations, alterations in a gene found for the first time in one family member, were believed to be mainly the result of new mutations in the sperm or eggs (germline) of one of the parents and passed on to their child.
Researchers from The Netherlands have now succeeded in determining that at least 6.5% of de novo mutations occur during the development of the child (post-zygotic) rather than from the germline of a parent.
A daily sugar-sweetened beverage habit may increase the risk for non-alcoholic fatty liver disease (NAFLD).
Elon Musk, and NASA both have in mind the idea of doing interplanetary voyages straight away, aiming for Mars, with Obama going so far as to say about the Moon: “But I just have to say pretty bluntly here: We’ve been there before.”. If you hold that view, you are undoubtedly in distinguished company.
Now - there are two things here - yes we've been to the Moon before - but is that the end of all interest in it? But first - how ready are we for interplanetary voyages?-->
For being so small, fruit flies have had a large impact on genetic research. Thomas Werner, an assistant professor of biological sciences at Michigan Technological University, has bridged the miniscule and the massive in an effort to better understand the mechanisms behind several unique features of fruit fly genes.
Over the past week, several studies that Werner co-authored have been published in PLoS ONE, the Proceedings of the National Academy of Sciences, and Nature Education. All are linked by Drosophila--a genus of fruit flies--and the insights that fruit fly genetics provide on human health, specifically cancer-causing genes.
The Global Sanitation Fund's latest Progress Report details how support for nationally-led programs has helped 7 million people in over 20,500 communities become open-defecation free, improved toilets for 4.2 million people and seen eight million people gain access to hand-washing facilities. The governments of Australia, Finland, the Netherlands, Sweden, Switzerland and the United Kingdom contributed.
Established by WSSCC, the GSF funds large-scale behavior change activities to help poor people in the world's hardest-to-reach areas attain safe sanitation and adopt good hygiene practices. The community-led, government-backed activities support existing national efforts, uniting a diverse group of stakeholders to address deficiencies in access to sanitation and hygiene.
Bariatric surgery does not only benefit the health of patients who undergo this weight loss procedure. It also leads to greater intimacy between them and their life partners, and adds a spark to their sex life. It's all in all a shared journey that brings partners closer together, says Mary Lisa Pories of East Carolina University in the US, lead author of a study providing insights into the experience of couples after one of the partners underwent weight loss surgery. The findings are published in Springer's journal Obesity Surgery.
Unlike other forms of methamphetamine available in Australia (speed or base), ice (crystalline methamphetamine or crystal meth) can be smoked. This gives a rapid drug effect because it gets into both the bloodstream and the brain quite quickly.-->
