Spying on Animals' Movements to Learn How They're Feeling

by Elizabeth Preston in Inkfish



Rory Wilson recalls some nervous waterbirds.

"I've seen pelicans in Galapagos, in the port," the Swansea University biologist says. One set of birds was standing by the fish-gutting area and waiting for scraps, while another group stood out of the fray in some nearby bushes. Although both sets of pelicans acted the same, a closer look at the birds waiting for fish scraps revealed that they were quaking slightly. The tips of their wings trembled.

Wilson thinks the tremor in the pelicans... Read more »

A new type of memory storage on the horizon

by Gabriel in Lunatic Laboratories

For those of us old enough to remember the days of the Apple II, you know that storage has exponentially increased. Even just 10 years ago 20+ gigs of data seemed huge, now my cellphone has 64 gigs. Yet we still need more data storage and we are looking for new ways to get it. Now a way to use weak molecular bonding interactions to create well-ordered and stable metal–organic monolayers with optoelectronic properties has been found. The development could form the basis for the scalable fabrica........ Read more »

Standard Model at the horizon

by Marco Frasca in The Gauge Connection

Hawking radiation is one of the most famous effects where quantum field theory combines successfully with general relativity. Since 1975 when Stephen Hawking uncovered it, this results has obtained a enormous consideration and has been derived in a lot of different ways. The idea is that, very near the horizon of a black hole, a […]... Read more »

Move over solar pannels, introducing spray-on solar cells

by Gabriel in Lunatic Laboratories

Solar panels, they are big, heavy, cannot flex, and are still very inefficient. While efficiency isn’t the big issue, flexibility has relegated solar panels to rooftops and solar farms. Well that is until now, researchers have just invented a new way to spray solar cells onto flexible surfaces using miniscule light-sensitive materials known as colloidal quantum dots (CQDs)—a major step toward making spray-on solar cells easy and cheap to manufacture....

ALMA Japan: Hi-Def Imaging of Spiral Gas Arms from Twin Baby Stars (w/video)

by DJ Busby in Astronasty

We know that about half the the stars out there (with sizes close to that of our sun) are binary systems. However, for a long time we've been lacking information on how they develop, since it's not been easy to get a whole lot of data from surrounding scattered mass that's so damned far away!

Blu-ray solar power

So here’s something you don’t see everyday.

As surprising as this was, there is even better news, we know why they improve performance.... Read more »

Found: The Ideal Fatness for Elephant Seals

by Elizabeth Preston in Inkfish

Like many new mothers, a female elephant seal puts herself on a strict diet after giving birth. She dives into the Pacific and spends two months eating everything she can find. It’s only by working hard at building up her blubber stores that she can get back her ideal body. Northern elephant seals (Mirounga angustirostris) […]The post Found: The Ideal Fatness for Elephant Seals appeared first on Inkfish.... Read more »

Where Do All Those Leaves Come From?!

by Mark E. Lasbury in The 'Scope

You rake leaves and lug them to the curb, or you push them into your neighbor’s yard with your blower. Either way, do you know where the matter/mass in all those leaves comes from? You won’t believe the answer. But the leaf may be passé. New research is showing how artificial leaves can produce oxygen for space travel and hydrogen for fuel cells.... Read more »

Understanding the past to know more about our future: study finds spikes in carbon dioxide levels correlated with end of last glacial cycle

by Jonathan Trinastic in Goodnight Earth

We've always thought that the last glacial cycle correlated with a slow rise in CO2, however new data from Antarctica shows quick spikes in CO2 and methane lasting under 100 years.

Tagged Dolphins Adjust by Swimming Slowly

by Elizabeth Preston in Inkfish

Scientists love the data they get by attaching electronic tags to animals, but these devices can be a literal drag. For animals that fly or swim, tags can mess up their mechanics and force them to spend more energy. That’s what scientists expected to see when they studied dolphins with data loggers suction-cupped to their […]The post Tagged Dolphins Adjust by Swimming Slowly appeared first on Inkfish....

Dude, wheres my Hover Car? Oh wait…

by Gabriel in Lunatic Laboratories

We all (of a certain age) remember the Jetsons, a futuristic family with hi-tech gadgets and gizmos. However, nothing said, “the future is here” quite like things hovering. Even in the movie Back to the future, they have hover boards and flying cars. Unfortunately we don’t, which is a shame because according to the 1950’s we are the future, we should have hover-cars and hover boards… well the wait is over. Yep, introducing the first real hover board!... Read more »

A Venusian Mystery Explored Once More

by Gabriel in Lunatic Laboratories

Venus, the place where women are from... supposedly. To say Venus has a harsh climate would be an understatement, this is one of many reasons why we will never (or maybe not soon) see a "long lasting" Venus rover counterpart to our Mars rover missions. Still, the planet (much like all the other plants) can teach us a lot about not just our own origins, but the origins of the universe. Also like all our neighbor planets Venus is hiding something beneath its brilliant shroud of clouds, a mystery t........ Read more »
