Over at Make: Blog, George Hart shows that if you put a challenge out
there, no matter how crazy, someone might just do it. So 15 years after
he made some plans for a theoretical sphere made with 480 wooden pieces
and 960 connections, someone actually built it. In this case it was

These flash drives by Shu-Chun Hsiao are serious. The drives are encased
in concrete and are embossed with the weight of each one, a number that
correlates with the flash drive’s capacity. I love the idea, but 256g
sticking out the front of my desktop is just going to destroy itself.
P.S. This wou…

Seed bombs are little balls of clay, compost, and seeds that you can
toss into a vacant lot to try and get some new plants to grow. It’s a
guerrilla gardening technique and you can see how to make one here . If
you just want to pick one up and live in San Francisco you can now buy
them from a vendin…

A prisoner in the UK wanted to ink some skin so badly he made a tattoo
machine from a Sony PlayStation. He did it by attaching a motor from the
PlayStation to a sharpened ballpoint pen. It must’ve worked because he
gave tattoos to others before he was caught it was taken away. Sony

An extremely rare " grolar bear "–a polar-grizzly bear hybrid–was shot and killed by an Inuit hunter in Canada’s Northwest Territories last month.
Global warming has reportedly been driving grizzly bears ( Ursus arctos horribilis ) farther north in search of food, bringing them into polar bear ( U. maritimus ) territory. Polar bears, meanwhile, are finding themselves stranded on land instead of their usual sea ice, bringing them into contact with the grizzlies.
Editor’s Note: Scientific American’s George Musser will be chronicling his experiences installing solar panels in Solar at Home (formerly 60-Second Solar). Read his introduction here and see all posts here .
Solar arrays can do more than feed energy into the power grid. They might also be able to help the grid cope with a problem many people aren’t aware of: the fact that electrical appliances not only consume energy, but also momentarily store and release it. The worst culprits are motors and transformers, whose internal magnetic fields represent a significant cache of energy, giving these devices a type of electrical inertia that causes them to get out of sync with the grid. To describe the problem and a possible solution, I’ve invited a two-part guest blog from Arnold Mckinley of Xslent Energy Technologies . Here’s part one.
LEH, INDIA–In the high-altitude desert of the Indian trans-Himalayas, one man is buying time for villagers suffering from global warming by creating artificial glaciers. [More]

As you read this sentence, you probably think that this moment–right now–is what is happening. The present moment feels special. It is real. However much you may remember the past or anticipate the future, you live in the present. Of course, the moment during which you read that sentence is no longer happening. This one is. In other words, it feels as though time flows, in the sense that the present is constantly updating itself. We have a deep intuition that the future is open until it becomes present and that the past is fixed. As time flows, this structure of fixed past, immediate present and open future gets carried forward in time. This structure is built into our language, thought and behavior. How we live our lives hangs on it.
Yet as natural as this way of thinking is, you will not find it reflected in science. The equations of physics do not tell us which events are occurring right now–they are like a map without the “you are here” symbol. The present moment does not exist in them, and therefore neither does the flow of time. Additionally, Albert Einstein’s theories of relativity suggest not only that there is no single special present but also that all moments are equally real [see “ That Mysterious Flow ,” by Paul Davies; Scientific American , September 2002]. Fundamentally, the future is no more open than the past.

BOMBARDIER TRAXX locomotives will operate double-deck coaches in the Mazovian region
Bombardier Transportation and “Koleje Mazowieckie – KM” Sp. z o.o. have signed an agreement for the delivery of eleven TRAXX electric locomotives. The value of the contract amounts to approximately 41 million euros ($54 million US). The delivery of the locomotives is scheduled for summer 2011.
TORRANCE, Calif., U.S.A., May 12, 2010 – Honda’s experimental Bodyweight Support Assist walking assist device will be showcased in the National Design Triennial “Why Design Now?” exhibition at the Cooper-Hewitt, National Design Museum, Smithsonian Institution in New York, NY, from May 14, 2010, through January 9, 2011. The exhibition of design innovation will showcase the work of designers from around the world that demonstrate the value of design in helping solve some of society’s most urgent human and environmental problems including sustainability, accessibility, universality, fair trade, conservation, health, education, creative capitalism, and underserved audiences. The designers are being recognized for enhancing human experience by inventing solutions that are as beautiful as they are just.
