Pavement to Parks

- Fono

Major cities like SF and NYC are beginning to realize they could do with a few less roads and parking lots — and they’re doing something about it.

In San Francisco, a handful of parking spaces and public right-of-ways are being remade into mini parks and plazas. Some are lined with trees sprouting from old dumpsters, others are buffered from traffic with large, discarded pipes; inside the improvised borders, tables, small patches of grass and concrete slabs are arranged for seating.

Meanwhile, the temporary pedestrian mall in Times Square is going to become permanent!

Virus Shown To Treat Prostate Cancer

- Dan Harrison

A team of researchers in Alberta have successfully tested a new way to treat prostate cancer with a virus. Viruses, which target specific cells, are injected into the body and seek out the mutations in cancer cells. The virus then replicates and causes the cancer cell to burst, sending thousands of viral particles into the surrounding tumour.

The six men in the study had the virus injected directly into their tumours three weeks before they had surgery to remove the prostate gland as part of standard treatment. The tumour cells are targeted by viruses in the experimental treatment, says Dr. Don Morris of the Tom Baker Cancer Centre in Calgary.

Signs of cancer-cell death were found in the removed prostate tumour, while the normal parts of the prostate showed minimal toxicity and no viral replication, Morris said.

Although this doesn’t represent a cure for cancer (tumours were very rarely completely eliminated), it may lead to cancer becoming a much more treatable illness.

Using Trees To Provide Clean Water.

- Dan Harrison

It turns out that trees can do more than just provide power! The Moringa tree, which grows in Africa, India, South East Asia, and Central and South America, is drought resistant and capable of producing cooking and lighting oil, soil fertilizer, and nutritious food.  In addition, it has be recently publicized that the seeds can reduce the bacteria count in previously untreated water by 90.00 – 99.99%! Although the process can be quite involved, it still has the potential to allow people to have unrestrained access to clean water.

Cuff the Heart

- Adam Clare

A new cuff can help save heart attack victims by limiting blood flow.

Ischemic preconditioning involves using the device to interrupt blood flow in the arm, off and on over a period of 35 to 40 minutes: the cuff is inflated for five minutes, then deflated for five minutes, with the procedure being repeated consecutively four times.

Once at the hospital, the patient receives routine heart attack treatment, including cardiac angioplasty. Preconditioning using the cuff may still be going on throughout this procedure, which uses a tiny inflatable balloon to open up narrowed or blocked blood vessels to the heart.

Researchers, whose paper appears in Friday’s issue of The Lancet, found that those heart attack patients randomly assigned to have preconditioning had an overall reduction in heart muscle damage of 30 per cent, compared to those not treated with the cuff.

Make a Boring Thing Fun by Adding More Boredom

- Adam Clare

I use this technique quite a lot, but somebody else wrote about it in a way better than I could. If you can do two boring tasks at the same time you’ll have an enjoyable experience.

I’ve noticed several related things: 1. I could easily study flashcards while walking. This was less mysterious because I coded walking as pleasant. 2. I can’ t bear to watch TV sitting down. Walking on a treadmill makes it bearable. This didn’t puzzle me because I coded TV watching as pleasant and sitting as unpleasant (although I sit by choice while doing many other things). 3. I have Pimsler Chinese lessons (audio). I can painlessly listen to them while walking. While stationary (sitting or standing), it’s hard to listen to them. 4. When writing (during which I sit), it’s very effective to work for 40 minutes and then walk on my treadmill watching something enjoyable for 20 minutes. I can repeat that cycle many times. 5. Allen Neuringer found he was better at memorization while moving than while stationary. 6. There’s some sort of movement/thinking connection — we move our arms when we talk, we may like to walk while we talk, maybe walking makes it easier to think, and so on.

You could say that walking causes a “thirst” for learning or learning causes a “thirst” for walking. Except that the “thirst” is so hidden I discovered it only by accident. Whereas actual thirst is obvious. The usual idea is that what’s pleasant shows what’s good for us — e.g., water is pleasant when we are thirsty. Yet if walking is good for us — a common idea — why isn’t it pleasant all by itself? And if Anki is good for us, why isn’t it pleasant all by itself? The Anki/treadmill symmetry is odd because lots of people think we need exercise to be healthy but I’ve never heard someone say we need to study to be healthy.
