Attempts to put a dollar value on the natural world – so-called “natural capital” or “ecosystem services” – have produced some frankly staggering numbers. A seminal 1997 paper valued the world’s ecosystem services at US$33 trillion (A$42 trillion) a year. This estimate was controversial, given that it dwarfed the entire global market economy, which at the time stood at roughly US$18 trillion a year.
New research published in Diabetologia shows that use of statins is associated with a 46% increase in the risk of developing diabetes, even after adjustment for confounding factors. The study is by Professor Markku Laakso, Institute of Clinical Medicine, University of Eastern Finland and Kuopio University Hospital, Finland, and colleagues.
The number of women in paid employment has risen significantly over the past 40 years. In developed countries especially, there are increasing numbers of women reaching top positions in different fields of work. And new research shows how girls are doing far better than boys educationally across the world.-->
The use of psychedelics, such as LSD and magic mushrooms, does not increase a person's risk of developing mental health problems, according to an analysis of information from more than 135,000 randomly chosen people, including 19,000 people who had used psychedelics, sponsored by an LSD advocacy group in Norway. The results are in Journal of Psychopharmacology.
Why can cancer cells be so resilient, even when faced with the onslaught of nearly toxic drug cocktails, radiation, and even our own immune system?
A new research report appearing in the March 2015 issue of The FASEB Journal, shows that intermediate filaments formed by a protein called "vimentin" or VIF, effectively "insulate" the mitochondria in cancer cells from any attempt to destroy the cell. Under normal circumstances, VIF serves as the "skeleton" for cells by helping them maintain their shapes.
Sunday marks the 106th celebration of International Women’s Day.
Since New Yorkers first celebrated it in 1909, American women have made great strides toward equality in the workplace, politics and at home. Long gone are the days when women couldn’t vote or sex discrimination was blatant and legal.
A new sequencing technique may provide a clearer picture of how genes in mitochondria, the "powerhouses" that turn sugar into energy in human cells, shape each person's inherited risk for diabetes, heart disease and cancer, according to a study.
The powerful new tool may help researchers better explain why some people get sick and others do not despite being the same age and weight, or having the same bad habits (e.g. smoking). Researchers have long sought to determine these risks by looking at diet and variations in nuclear genes inherited from both parents. These analyses have left out differences in mitochondrial genes (mtDNA), the second kind of DNA in every cell, which we inherit from our mothers.
Planning permission has been given for what could become the world’s largest offshore wind farm on the Dogger Bank, off England’s east coast.
If fully constructed, the project will have up to 400 turbines with a total generation capacity of 2.4 GW. That’s enough to power 1.9 million households – more than Manchester and Birmingham combined.
The NASA spacecraft Dawn has spent more than seven years traveling across the Solar System to intercept the asteroid Vesta and the dwarf planet Ceres.
Now in orbit around Ceres, the probe has returned the first images and data from these distant objects.
But inside Dawn itself is another first – the spacecraft is the first exploratory space mission to use an electrically-powered ion engine rather than conventional rockets.
Intensified land-use, sewage discharge, and climate change have likely favored disproportionate development of harmful algae in freshwaters. A new study found that blooms of one type of harmful algae, called cyanobacteria, have increased disproportionately over the past two centuries relative to other species, with the greatest increases since 1945.
Cyanobacteria pose a serious threat to drinking water sources worldwide because they can release toxins into the surrounding environment.
Evaluations of research ethics do not benefit from a tick-box approach.
Australia’s social science research, like that in most developed countries since the infamous Milgram experiments took place at my alma mater in 1961, occurs under the watchful eye of ethics boards.
New gaps are opening up in educational achievement between teenage boys and girls, according to a comprehensive new report from the Organisation for Economic Co-operation and Development (OECD).
Analysis of its 2012 Programme for International Student Assessment (PISA) tests of 15-year-olds in reading, mathematics and science across countries, shows that unfortunately, patterns between the performance of girls and boys have not changed much over time, although some of the gaps have closed a little.-->
A deadly fungus responsible for the extinction of more than 200 amphibian species worldwide has coexisted harmlessly with animals in Illinois and Korea for more than a century, a pair of studies have found.
Amphibians in Illinois have been coexisting with the fungus Batrachochytrium dendrobatidis, or Bd, for at least 126 years without adverse effects seen in other parts of the world such as mass-die offs, according to research published Jan. 13 in the journal Biological Conservation. In a study published March 4 in PLOS ONE, researchers were able to date the fungus in Korea back to 1911. The results will help scientists better understand the disease caused by Bd, chytridiomycosis, and the conditions under which it can be survived.
You can see it through a telescope, or watch a documentary about it, but you can't stick your nose out and take a whiff. Speaking of Chemistry returns this week to answer the very important question, "What does space smell like?" Matt Davenport, Ph.D., reveals the stinky secrets of the cosmos from the people who have been there.
Only 14% of young women who enter university for the first time chose science-related fields of study such as engineering, manufacturing and construction. This is one of the headline findings of a new report from the Organisation for Economic Co-operation and Development that examines gender equality in education across 64 countries and jurisdictions. In comparison, 39% of young men who entered university chose to pursue one of those fields of study.
