Open Source Seeds

Irwin Goldman, a vegetable breeder at the University of Wisconsin, Madison, helped organize the campaign. It’s an attempt to restore the practice of open sharing that was the rule among plant breeders when he entered the profession more than 20 years ago.
Good for them. This needs to be supported. The crazy practices of seed companies shouldn’t be legal but they pay lots of cash to politicians and the corrupt politicians (which seems to be an awful lot of them) write bad policy and encourage bad regulation.
Even those administrators taking control of universities have subjugated the search for knowledge and improvement to seek monetary gain instead of what the universities used to prioritize. It is a shame and those that have distorted universities so much should be ashamed.
Initial efforts that lead to the bad place we find universities in now were to promote the adoption of university research. To do so they partnered with business in sensible ways. Then administrators saw money was being made and turned the priority into making money and if that meant restricting the benefits to society of university research so be it. This has created universities that have lost ethical foundations and have destroyed a big part of the value universities used to provide society.

How Healthy Is Squid for Us?
Posted on April 19, 2014 Comments (1)
I try to eat healthfully, especially when I can tweak what I eat to gain a health advantage. I know fish have good qualities. I live in Malaysia now and squid (called sotong here) is often available. I often prefer squid to fish here as the fish use here are often fairly small with bones to deal and not much meat for the effort (it is great sometimes but I am often lazy).
So I looked online for some details, it wasn’t as easy I would have hoped. The Shellfish Association of Great Britain offered a good overview.
They say 100g of raw squid (pre cooking weight) provides about 200% of Vitamin B12, 100% of Selenium, 80% of Copper, 50% of Vitamin B6, 35% of Vitamin E, 34% of Phosphorous, 30 % of Protein, 20% of Niacin, 10% of B1 (Thiamin), 8% of Potassium, 10% of Magnesium, 14% of Zinc.
From various sources online it seems there are 92 calories in 100 grams of Squid with a calorie breakdown of 72% protein, 14% fat and 14% carbs.
From the Heart Association of Australia “omega-3s are found primarily in oily fish, such as Atlantic and Australian salmon, blue-eye trevalla, blue mackerel, gem fish… Other fish such as barramundi, bream or flathead, and seafood such as arrow squid, scallops and mussels, are also good sources of omega-3… To reduce the risk of heart disease, the Heart Foundation recommends that Australian adults consume about 500 milligrams of omega-3 (marine source) every day.”
Using Drones to Deliver Medical Supplies in Roadless Areas

This is an awesome use of technology to tackle important problems. Engineers are great.
[Andreas] Raptopoulos said the new system would be used to leapfrog the building of infrastructure, in the same way mobile networks have overtaken fixed lines in poorly connected countries.
In sub-Saharan Africa, 85% of roads are inaccessible during the wet season, cutting off huge swaths of the population and hindering the transport of medical supplies, he said.
There are three parts to the system delivering medical goods: the UAVs themselves, landing stations where packages can be dropped off and transferred, and the software that ensures vehicles get securely from point to point. Because of their short battery life, networks of drones are needed to work together, shuttling between ground stations
Approximate costings from Matternet put the price of unmanned aerial vehicles at £6,000 each and ground stations at £3,000 each. A network of five ground stations and 10 UAVs, as well as setup and training, would cost a charity in the region of £90,000, according to Raptopoulos. An eight-propeller drone can carry 2kg and travel 10km in good weather. Batteries need to be replaced every 600 cycles.
They are hiring: software engineer and avionic engineering right now. They are Palo Alto, California.
Alternative Career Paths Attract Many Women in Science Fields
Posted on April 5, 2014 Comments (2)
Instead of following traditional paths, women are using their science, technology, engineering, and math degrees to create new careers.
Because women have traditionally been excluded from these disciplines, and because their fresh eyes allow them to make connections between fields, many women are launching careers, and even entire industries, based on a flexible and creative definition of what it means to be a scientist, artist, or engineer. K-12 schools have done a particularly poor job of integrating study across STEM fields and encouraging creativity and interdisciplinary connections.
We continue to teach science, technology, and math in isolation, as if they have little to do with one another. This sort of compartmentalized approach runs counter to what we know about effective learning: Students need to be able to connect content knowledge and concepts to real-world applications in order to develop mastery and passion for a subject.
The challenge for anyone seeking to forge a brave new path through STEM careers, particularly ones that involve interdisciplinary study and practice, is the challenge of job stability. Kendall Hoyt, professor of technology and biosecurity at Thayer School of Engineering explained, “Interdisciplinary career paths are easier to create than they are to sustain, because there is not an established career trajectory and evaluation system.”
The challenge of how to maximize the opportunities for those interested in careers in science, technology, engineering and math is important to all economies. There are difficulties in doing this and so continued focus on this area is good. My personal belief is we focus too much on the gender issue. Yes, we should reduce discrimination. I think we have done well but still have further to go.
Most of the suggested changes in how things should be done help women and also plenty of men that are turned off by the old way of doing things.
I also think we need to be careful in how we use data. Clamoring about discrepancies in a field with far more men (say physics) while not doing the same about a field with far more women (say psychology) is questionable to me. I don’t believe that any field that isn’t 50% male and 50% female is evidence that we need to fix the results so they are 50% each.
I believe we should provide everyone the opportunity to pursue the interests they have. They must perform to earn the right to continue. And we don’t want to waste potential with foolish barriers (for women, minorities or men). But if we do so and certain fields attract more women and others attract more men I think we can waste our effort by being too worried that certain fields are problematic.
If we are concerned it should be based on data and looking at the real world situation. In the coming decades my guess is women will exceed men in careers in many science disciplines (engineering still has fairly high male bias overall though some field, such as bio-engineering are already majority female graduates). It starts with education and women are already the majority of undergraduate degrees in science and engineering overall. And in many disciplines they dominate.
