Water is two parts hydrogen and one part oxygen. What if someone says, “Well, that’s not how I choose to think about water”? All we can do is appeal to scientific values. And if they don’t share those values, the conversation is over. If someone doesn’t value evidence, what evidence are you going to provide to prove that they should value it? If someone doesn’t value logic, what logical argument could you provide to show the importance of logic?

Kinetic energy generation from footsteps

Footsteps can power the world. Seriously, this is really exciting. What started off as a Kickstarter campaign, the concept “harnesses the kinetic energy from footsteps and converts it into renewable electricity. By stepping, jumping, or hopping on a ‘pavegen floor tile’, users create clean, off-grid electricity used to power multiple applications – from lighting, to interactive learning displays and charging points.”

Self-filling water bottle draws water from the air.

The water bottle draws inspiration from the Namib Desert beetle, which is able to draw in 12 percent of its weight in water from the air using hydrophilic areas on its back which cause water to condense.

“We use nanotechnology to mimic this beetle’s back so that we too can pull water from the air,” Sorenson told PRI. “We see this being applicable to anything from marathon runners to people in third-world countries, because we realize that water is such a large issue in the world today, and we want to try to alleviate those problems with a cost-efficient solution. We are looking to incorporate this in greenhouses or green roofs in the immediate future, and then later on, we’re looking to see how far we can really scale this up to supply maybe farms or larger agricultural goals.”

Arguably the most remarkable part might be that fact that Sorenson insists the technology does not require much energy; he said the company’s showed how solar cells and a rechargeable battery can be enough. This means the device could potentially be attached to vehicles, buildings, or even a running human, and still be able to grab all the power it needs supply to move the air over the specially-coated surface.

How’s this for an innovative startup: four African girls — the eldest of which is just fifteen years old — have worked together to invent a generator that’s powered by urine. The group presented their creation at this year’s Maker Faire Africa, and it’s so freaking brilliant it makes me want travel back in time and punch 15-year-old me right in the solar plexus.

Possibly one of the more unexpected products at Maker Faire Africa this year in Lagos is a urine powered generator, created by four girls.

The girls are Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15). 1 Liter of urine gives you 6 hours of electricity.

BBC News - Dolphins deserve same rights as humans, say scientists

Dolphins should be treated as non-human "persons", with their rights to life and liberty respected, scientists meeting in Canada have been told.


"We're saying the science has shown that individuality - consciousness, self-awareness - is no longer a unique human property. That poses all kinds of challenges."

Wenn Zweisprachige die Sprache wechseln, so ändert sich auch ihr Geschlechterbild, etwa was "männliche" oder "weibliche" Berufe sind. Dies ergab eine Studie von PsychologInnen der Universität Freiburg. Sie untermauert die These, dass zwischen Sprache und Gedanken ein enger Bezug besteht. › Wissenschaft

So schätzen Männer ihre Mathematikfähigkeiten und Frauen ihre Sprachfähigkeiten besser ein, wenn sie am Anfang eines Fragebogens ihr Geschlecht angeben mussten, als wenn das nicht gefragt war. Das einfache Ankreuzen eines Kästchens reicht offenbar, um Genderunterschiede hervorzurufen [...]

Men and science: LOL


I’m not a misandrist, but men really need to stop trying to understand science. It’s really CUTE how they try and all, but they always end up getting mixed up and making fools of themselves. It’s not their fault—their brains are just not wired to understand complex concepts like asexual cloning.

PS: HEY ANON: With asexual cloning, MEN will be just as obsolete as WOMEN in terms of reproduction. *patpat* YOU TRIED.

The 173-page report concludes: "Taking drugs does not always cause problems, but this is rarely acknowledged by policymakers. In fact most users do not experience significant problems, and there is some evidence that drug use can have benefits in some circumstances."

People with higher intelligence tend to have a harder time falling asleep at night because of increased brain activity.

That explains why I fall asleep so easily…

[Note: The original source doesn't exactly state quoted fact. It just says night owls tend to have a higher IQ than people who rise early.]

Babies Are Born Scientists

Very young children’s learning and thinking is strikingly similar to much learning and thinking in science, according to Alison Gopnik, professor of psychology and affiliate professor of philosophy at the University of California, Berkeley. Gopnik’s findings are described in the Sept 28 issue of the journal Science. She spoke about her work in a video briefing with NSF. New research methods and mathematical models provide a more precise and formal way to characterize children’s learning mechanisms than in the past. Gopnik and her colleagues found that young children, in their play and interactions with their surroundings, learn from statistics, experiments and from the actions of others in much the same way that scientists do.
