Dogger Bank: Submerged Island Is The Perfect Spot For The World's Biggest Wind Farm

Science2.0 - 55 min 14 sec ago

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.

Destination Ceres: Inside The Dawn Spacecraft's Revolutionary Ion Engine

Science2.0 - 1 hour 50 min ago

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.

Human Activity May Be Supporting Growth Of Harmful Algae In Lakes

Science2.0 - 2 hours 15 min ago

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.

University 'Ethics Boards' As A Way To Evade Scientific Controversy

Science2.0 - 5 hours 1 min ago

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.

Mitochondria - The Chemists' Organelle

Science2.0 - 9 hours 32 min ago
I am writing a book on mitochondria and after a few months of research you begin to see a common thread - serendipity.  Sometimes big things happen because of what seems to be luck, a group of people all happen to be in one place at one time, they are all spurred on by each other and then dramatic things occur.

Obsessing Over Gender Differences In Test Scores Won’t Fix Anything

Science2.0 - 11 hours 50 min ago

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.

Fast Food Commercials Aimed At Kids 'Deceptive'

Science2.0 - 11 hours 54 min ago
Fast food advertising doesn't emphasize healthy menu items enough, and by giving away toys in things like Happy Meals restaurants are being deceptive even by their own self-regulation standards, according to scholars who showed 100 children aged 3–7 years McDonald’s and Burger King children and adult meal ads, randomly drawn from ads that aired on national U.S. television from 2010–11.

After seeing the ad, children were asked to recall what they had seen and transcripts evaluated for descriptors of food, healthy food (apples or milk), and premiums/tie-ins. All children’s ads contained images of healthy foods, like apples and milk, but premiums/tie-ins were recalled much more frequently than healthy food.

Deadly Frog Fungus Dates Back To 1880s

Science2.0 - 12 hours 38 min ago

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.
