Lead pollution and industrial opportunism in China

By Tee L. Guidotti

Mengxi Village, in Zhejiang province, in eastern coastal China, is an obscure rural hamlet not far geographically but far removed socially from the beauty, history, and glory of Hangzhou, the capital. Now it is the unlikely center of a an environmental health awakening in which citizens took direct action by storming the gates of a lead battery recycling plant that has caused lead poisoning among both children and adults in the village.

SciWhys: How does an organism evolve?

By Jonathan Crowe
The world around us has been in a state of constant change for millions of years: mountains have been thrust skywards as the plates that make up the Earth’s surface crash against each other; huge glaciers have sculpted valleys into the landscape; arid deserts have replaced fertile grasslands as rain patterns have changed. But the living organisms that populate this world are just as dynamic: as environments have changed, so too has the plethora of creatures inhabiting them. But how do creatures change to keep step with the world in which they live? The answer lies in the process of evolution.

Last refuge or no hiding place? The last scene of all.

By David Jolley
As young fit people, few of us have ambition to spend our last days with others in a Home shared with others who have become impaired, disabled and dependent on care from others. Older and nearer this reality we may find that it has its attractions.

On the future of medical textbooks

By John Firth
Medical textbooks are often spoken of as dinosaurs – they may have dominated the medical world years ago, but things have moved on, and they’re now out-of-date and heading towards extinction with the Dodo. While there is some truth in this, it’s not the whole truth, and it’s my feeling that medical textbooks will continue to play a big part in the future of medical publishing, albeit in a different form.

Long term care and older people

By Tom Dening
Suddenly care homes are hot news. As I drove to work this week, the two leading national stories were both on this topic. First was the shocking care provided to the residents of Winterbourne View in Bristol. As one scene of abuse was followed by another, the whole effect was increasingly distressing and I could only watch to the end in order to ensure that action was going to follow. ‘Call the police’ was going through my head throughout. The second story was about Southern Cross, the care home provider that expanded rapidly but has now run into trouble as its income can no longer finance the rents for the homes.

Neuromania

By Paolo Legrenzi and Carlo Umlitá
Increasingly often, the press offers explanations of human behaviour by drawings, photographs, and graphic descriptions of sections of the brain which show that part of our grey matter that is activated when we think about something or plan an action. We are told that how we behave depends on the functioning of certain neurons. We hear about new disciplines such as neuroeconomics, neuroaesthetics, neuroethics, neuropolitics, neuromarketing, and even neurotheology (over 20,000 results on Google!).

Fertility and the full moon

By Allen J. Wilcox

In her novel, Prodigal Summer, Barbara Kingsolver celebrates the lush fecundity of nature. The main character marvels at the way her ovulation dependably comes with the full moon.

It’s a poetic image – but is there any evidence for it?

Actually, no. It’s true that the length of the average menstrual cycle is close to the length of the lunar cycle. But like

SciWhys: What is gene mutation?

By Jonathan Crowe
In my last three posts I’ve introduced you to the world of biological information, taking you from the storage of biological information in libraries called genomes, which house information in individual books called chromosomes (themselves divided into chapters called genes), to the way the cell makes use of that stored information to manufacture the molecular machines called proteins.

A passionate “green” Calvinism

By Belden C. Lane

Who would think to find a green theology, celebrating the earth’s startling beauty, in somber, Calvinist Geneva? Who would expect lusty commentaries on the Song of Songs, delighting in sex and natural beauty, in the austere meeting houses of Puritan New England? Who would imagine a vibrant nature mysticism in the writings of Jonathan Edwards, author

For ‘in vitro’, 15 is the perfect number

By Dr Sesh Kamal Sunkara

In vitro fertilization (IVF) involves the retrieval of an egg and fertilization with sperm in the laboratory (in vitro) as opposed to the process happening within the human body (in vivo), with a natural conception. IVF was first introduced to overcome tubal factor infertility but has since been used to alleviate all types of infertility and nearly four million babies have been born worldwide as a result of assisted reproductive technology.

Does exercise really boost your mood?

By Michael Otto

In the New York Times, Gretchen Reynolds posed the question, “Does exercise really boost your mood?” There is a clear, clean answer to this question – yes! In fact, the evidence that regular, moderate exercise can boost your mood is overwhelming. From population-based studies to well-controlled clinical trials – exercise is associated with better mood. Specifically, exercise is

The most human computer?

By Dennis Baron
Each year there’s a contest at the University of Exeter to find the most human computer. Not the computer that looks most like you and me, or the computer that can beat all comers on Jeopardy, but the one that can convince you that you’re talking to another human being instead of a machine.

To be considered most human, the computer has to pass a Turing test, named after the British mathematician Alan Turing, who suggested that if someone talking to another person and to a computer couldn’t tell which was which, then that computer could be said to think. And thinking, in turn, is a sign of being human.

“Free”dom and consumer rights

By Andrew Trask
In 2002, the Concepcion family received a “free” cell phone when they signed up with AT&T. Unfortunately, the free phone was not as free as the Concepcions thought; AT&T charged them sales tax for it. The Concepcions were angry, and sued. Their case was merged with a large class action. AT&T invoked its right (hidden in the fine print of its cell-phone contract) to arbitrate the case. The arbitration provision was pretty generous: the Concepcions would not have to pay any costs, and if they won more from the arbitrator than AT&T offered in settlement, AT&T would give them $7,500.

The belated revenge of the health care Grinches

By Edward Zelinsky
It hasn’t been fun being a health care Grinch. Until recently, we health care Grinches have been the objects of bi-partisan scorn.

We have been warning that health care cost control will be painful and will entail reduced medical services and lower payments to health care providers. “Nonsense,” retorted President Obama. Taking a page from the Republican book of bromides as he plugged his health care reforms, Mr. Obama assured the nation that health care costs can be controlled painlessly, by purging “waste” and “fraud.”

Boobies, for fun & profit

By Gayle Sulik
A blogger who goes by the name of The Accidental Amazon recently asked: “When did breast cancer awareness become more focused on our breasts than on cancer? Is it because our culture is so obsessed with breasts that it slides right past the C word?”

The Amazon’s questions are important — but they are inconvenient; blasphemous to the pink consumption machine, disruptive to the strong societal focus on pink entertainment,

Chernobyl disaster, 25 years on

On April 26, 1986, the world’s worst nuclear power plant accident occurred at the Chernobyl nuclear power station. Now, 25 years later, the current crisis in Fukushima is being called the “worst since Chernobyl.” Will we avoid another disaster? And further more, in another 25 years, how will we feel about nuclear energy?
