Engineering Mosquitos to Prevent the Transmission of Diseases

Mosquitos are responsible for huge amount of suffering and death. In 2015 200,000,000 people were infected with malaria and 500,000 died.

It is amazing what knowledge science has provided about the causes of human disease. It is great to have videos like this available that let us learn a bit about it from a short and understandable video.

Using our scientific knowledge to design and implement solutions offers great possibilities. But we also have to worry about the risks of such attempts. Making decisions about what risks to take requires well informed people that are able to understand the opportunities and risks and make intelligent decisions.

Deadly Trio of Acidification, Warming and Deoxygenation Threaten Our Oceans

An international panel of marine scientists is demanding urgent remedies to halt ocean degradation based on findings that the rate, speed and impacts of change in the global ocean are greater, faster and more imminent
than previously thought.

Professor Dan Laffoley, International Union for Conservation of Nature, said: “What these latest reports make absolutely clear is that deferring action will increase costs in the future and lead to even greater, perhaps irreversible, losses. The UN climate report confirmed that the ocean is bearing the brunt of human-induced changes to our planet. These findings give us more cause for alarm – but also a roadmap for action. We must use it.“

Results from the latest International Programme on the State of the Ocean (IPSO)/IUCN review of science on anthropogenic stressors on the ocean go beyond the conclusion reached last week by the UN climate change panel the IPCC that the ocean is absorbing much of the warming and unprecedented levels of carbon dioxide and warn that the cumulative impact of this with other ocean stressors is far graver than previous estimates.

Decreasing oxygen levels in the ocean caused by climate change and nitrogen runoff, combined with other chemical pollution and rampant overfishing are undermining the ability of the ocean to withstand these so-called ‘carbon perturbations’, meaning its role as Earth’s ‘buffer’ is seriously compromised.

Professor Alex Rogers of Somerville College, Oxford, and Scientific Director of IPSO said: “The health of the ocean is spiraling downwards far more rapidly than we had thought. We are seeing greater change, happening faster, and the effects are more imminent than previously anticipated. The situation should be of the gravest concern to everyone since everyone will be affected by changes in the ability of the ocean to support life on Earth.”

Among the latest assessments of factors affecting ocean health, the panel identified the following areas as of greatest cause for concern:

Anti-Science Politics in Australia, Canada and the UK

Age of Unreason by George Monbiot

The governments of Britain, Canada and Australia are trying to stamp out scientific dissent.

in Canada… scientists with government grants working on any issue that could affect industrial interests – tar sands, climate change, mining, sewage, salmon farms, water trading – are forbidden to speak freely to the public(17,18,19). They are shadowed by government minders and, when they must present their findings, given scripts to memorise and recite(20). Dozens of turbulent research programmes and institutes have either been cut to the bone or closed altogether(21).

In Australia, the new government has chosen not to appoint a science minister(22). Tony Abbott, who once described manmade climate change as “absolute crap”(23), has already shut down the government’s Climate Commission and Climate Change Authority(24).

Follow the link for sources. Sadly governments are fighting for the crown of how anti-science they can be. It isn’t a matter of the countries that are doing a good job and a better job of using scientific understanding to aid in policy decisions. It is a matter of how extreme the anti-science crowds are in each country.

Trashing the scientific method and the use of scientific knowledge to pursue a pre-determined political agenda is a foolhardy action putting political expediency above effectiveness. Making political judgement, considering the available scientific research is fine, and will result in some people being upset. But the extremely bad process behind ignoring and intentionally sabotaging the use of data and scientific thinking is extremely harmful to society.

Every man has a right to his own opinion, but no man has a right to be wrong in his facts.
– Bernard Baruch (Daniel Patrick Moynihan said something very similar later)

Repair Cafes in The Netherlands

Repair Cafes in The Netherlands Give Life Back to Broken Objects

A new brand of DIY self-sufficiency is spreading across The Netherlands. Skilled craftswomen, mechanics, seamstresses, and handypersons are banding together to resist disposable consumer culture. It is the rise of the Repair Cafe, a place where neighbors get together to extend the life of their material belongings. “Fixers” mend clothes, restore furniture, rehabilitate electrical appliances, and enjoy each other’s company while industriously toiling away. The first cafe was founded by Martine Postma in Amsterdam in October of 2009. Today, there are 20 fully operational Repair Cafes, and 50 more in the planning stages.

I really like these efforts. We throw away too much stuff that has plenty of useful life left. Also it is a great way to build community. And it is an interesting way to learn about products we use everyday (both by fixing them and having your items fixed). The throw away culture is something we should aim to change. By these actions and also by engineers designing products to be fixed instead of thrown away. I donated to a similar fixer collective in Brooklyn via Kickstarter.
