But Carole Kleis isn’t just any woman — she’s the wife of a farmer, and a little natural fertilizer doesn’t bother her a bit, even if this particular usage is rather unusual.
"He's done weird things before for birthdays," she said. "But maybe not this weird." [...]
"I was going to put a heart out there after the happy birthday, but I ran out of manure," he said. "It's not hard. Any manure will work but the good, soft, gushy, warm stuff works the best. It kind of melts the snow."
The silicon photonics technology that is being developed with these chips integrates optical circuits onto a small chip: Light can be manipulated on submicrometer scale in tiny strips of silicon called waveguides or photonic wires. Using the unique properties of silicon, combined with state-of-the-art manufacturing technology, these silicon photonic circuits can pack a million times more components on the same footprint as today’s commercial glass-based photonics.
Every year for the past decade, Duck Tape brand duct tape has held a contest for the creative use of their tape in prom dresses and tuxedos. Winners earn scholarship money. Gallery at the link.

This year’s 72-student class is split into four groups that rotate through five courses during the day: Codeworlds (math/English), Being, Space and Place (social studies/English), The Way Things Work (math/science), Sports for the Mind (game design), and Wellness (health/PE). Instead of slogging through problem sets, students learn collaboratively in group projects that require an understanding of subjects in the New York State curriculum. The school’s model draws on 30 years of research showing that people learn best when they’re in a social context that puts new knowledge to use. Kids learn more by, say, pretending to be Spartan spies gathering intel on Athens than by memorizing facts about ancient Greece.
Most sixth-graders don’t expect to ever need to identify integers, but at Quest, it’s the key to a code-breaking game. In another class, when creatures called Troggles needed help moving heavy objects, the class made a video instructing how long a ramp they should build to minimize the force they needed to apply. “They’re picking concepts up as well as, if not better than, at other schools,” says Quest’s math and science teacher Ameer Mourad. Beyond make-believe, Quest is the first middle school to teach videogame design. Salen says building games teaches students about complex systems, which will prepare them for growing fields such as bioinformatics.
The assimilation of viral sequences into the host genome is a process referred to as endogenization. This occurs when viral DNA integrates into a chromosome of reproductive cells and is subsequently passed from parent to offspring. Until now, retroviruses were the only viruses known to generate such endogenous copies in vertebrates. But Feschotte said that scientists have found that non-retroviral viruses called bornaviruses have been endogenized repeatedly in mammals throughout evolution.
Bornavirus (BDV) owes its name to the town of Borna, Germany, where a virus epidemic in 1885 wiped out a regiment of cavalry horses. BDV infects a range of birds and mammals, including humans. It is unique because it infects only neurons, establishing a persistent infection in its host's brain, and its entire life cycle takes place in the nucleus of the infected cells.
The fluid proposed by Ji-Ping Huang of Fudan University in Shanghai, China, and colleagues, contains magnetite balls 10 nanometres in diameter, coated with a 5-nanometre-thick layer of silver, possibly with polymer chains attached to keep them from clumping.
In the absence of a magnetic field, such nanoparticles would simply float around in the water, but if a field were introduced, the particles would self-assemble into chains whose lengths depend on the strength of the field, and which can also attract one another to form thicker columns.
The chains and columns would lie along the direction of the magnetic field. If they were oriented vertically in a pool of water, light striking the surface would refract negatively – bent in way that no natural material can manage.
This property could be exploited for invisibility devices, directing light around an object so that it appears as if nothing is there, or be put to use in lenses that could capture finer details than any optical microscope.
[The bowling green. Enter THE KNAVE, WALTER and DONALD, to play at ninepins]
WALTER
In sooth, then, faithful friend, this was a rug of value? Thou wouldst call it not a rug among ordinary rugs, but a rug of purpose? A star in a firmament, in step with the fashion alike to the Whitsun morris-dance? A worthy rug, a rug of consequence, sir?
THE KNAVE
It was of consequence, I should think; verily, it tied the room together, gather’d its qualities as the sweet lovers’ spring grass doth the morning dew or the rough scythe the first of autumn harvests. It sat between the four sides of the room, making substance of a square, respecting each wall in equal harmony, in geometer’s cap; a great reckoning in a little room. Verily, it transform’d the room from the space between four walls presented, to the harbour of a man’s monarchy.
WALTER
Indeed, a rug of value; an estimable rug, an honour’d rug; O unhappy rug, that should live to cover such days!
DONALD
Of what dost thou speak, that tied the room together, Knave? Take pains, for I would well hear of that which tied the room together.
