How the First Nine Months Shape the Rest of Your Life
By ANNIE MURPHY PAUL Wednesday, Sep. 22, 2010
Heide Benser / Corbis
What makes us the way we are? Why are some people predisposed to be anxious, overweight or asthmatic? How is it that some of us are prone to heart attacks, diabetes or high blood pressure?
There's a list of conventional answers to these questions. We are the way we are because it's in our genes. We turn out the way we do because of our childhood experiences. Or our health and well-being stem from the lifestyle choices we make as adults.

One woman's dream to create national parks in the sea
SHAUL SCHWARZ / REPORTAGE BY GETTY FOR TIME
The Sargasso Sea has no shores. The 2 million-sq.-mi. body of water in the middle of the Atlantic is defined by two features: the ocean currents forming the North Atlantic subtropical gyre, which cycles around the sea, and sargassum, the free-floating golden-brown seaweed. The sargassum can be found scattered throughout the sea, sometimes entwined in vast waterborne mats. When Christopher Columbus encountered the sargassum while crossing the Atlantic, he ordered his men to fathom the depths, believing he had struck land. The oceanographer Sylvia Earle, though she prefers not to think in land-based metaphors, calls the sargassum "the golden rain forest of the sea," a base for scores of juvenile creatures, a floating nursery in a sea that was long believed to be a watery desert. She has traveled to Bermuda, on the western fringes of the Sargasso Sea, to see the sargassum and the ocean life she has worked for decades to protect. "The sargassum is the shelter," she says as her boat passes beyond Bermuda's coral reefs. "It is the island in the stream."/.../

Albert Einstein proposed that time is a relative concept and the higher you live
above sea level the faster you should age
Scientists use atomic clocks to show that time moves faster at altitude,

The world’s most accurate clock has neatly shown how right Albert Einstein was 100 years ago, when he proposed that time is a relative concept and the higher you live above sea level the faster you should age.
Einstein’s theory of relativity states that time and space are not as constant as everyday life would suggest. He suggested that the only true constant, the speed of light, meant that time can run faster or slower depending on how high you are, and how fast you are travelling.
Now scientists have demonstrated the true nature of Einstein’s theory for the first time with an incredibly accurate atomic clock that is able to keep time to within one second in about 3.7 billion years – roughly the same length of time that life has existed on Earth./.../

The Secrets of the Supercentenarians
By Samiha Shafy
How is it possible to live more than a century yet still remain healthy and lucid? Scientists believe there may be a genetic link. The Kahn siblings in America, aged 108, 104 and 100, are helping researchers to unlock those secrets.
Helen is 108 years old. She hates salads, vegetables, getting up early and just about everything that has to do with a healthy lifestyle. She loves rare hamburgers, chocolate, cocktails and nightlife in New York: all the exotic restaurants, Broadway shows, movie theaters — where she recently saw “Iron Man 2″ — and the Metropolitan Opera. That’s where she attended her first opera, “Samson et Delila,” in 1918. It was a present from her father for her 17th birthday.
State of the Heart’ CVD Report
Every year, 17.1 million lives are claimed by the global burden of heart disease and stroke - 82% of which are in the developing world . The number of deaths – especially in low- and middle-income countries (LMICs) – is alarming and saddening, particularly since through steps such as eating a healthy diet, regular physical activity and avoiding tobacco, the majority of these deaths could be prevented.
On the occasion of the 10th anniversary of World Heart Day the World Heart Federation, in partnership with the World Health Organization (WHO) and the World Economic Forum (WEF), is launching the ‘State of the Heart’ CVD Report.
- The World Heart Federation has initiated this report – the first of its kind – to reflect on the great achievements in cardiovascular disease (CVD) over the past decade, and raises awareness of the challenges still ahead of us in the fight against the number one killer worldwide.
- The report also calls upon employers, healthcare professionals, policy-makers and other stakeholders to implement the necessary activities to fight the growing burden of CVD.
New Discoveries into the Pathogenesis of Type 1 and Type 2 Diabetes

What is social cohesion?
As a concept, social cohesion has a long tradition in academic enquiry. It is of fundamental importance when discussing the role of consensus and conflict in society. From the mid‐1990s, interest in the dynamics of social cohesion grew amid concerns prompted by the impact of globalisation, economic change and fears fuelled by the ‘war on terror’. There is, however, no agreed definition of social cohesion. Most current definitions dwell on intangibles, such as sense of belonging, attachment to the group, willingness to participate and to share outcomes. They include three common elements: Shared vision: Most researchers maintain that social cohesion requires universal values, mutual respect and common aspirations or identity shared by their members.
A property of a group or community: Social cohesion tends to describe a well‐functioning core group or community in which there are shared goals and responsibilities and a readiness to cooperate with the other members.
A process: Social cohesion is generally viewed not simply as an outcome, but as a continuous and seemingly never‐ending process of achieving social harmony.
Differences in definition concern the factors that enhance (and erode) the process of communal harmony, and the relative weight attached to the operation of specific factors. The key factors are:
Economic: Levels of unemployment and poverty, income distribution, population mobility, health, life satisfaction and sense of security, and government responsiveness to issues of poverty and disadvantage.
Political: Levels of political participation and social involvement, including the extent of voluntarism, the development of social capital, understood in terms of networks, norms and social trust that facilitate coordination and co‐operation for mutual benefit.
Socio‐cultural: Levels of consensus and divergence (homogeneity and heterogeneity) on issues of local and national significance.
The present survey has adopted an eclectic, wideranging approach, influenced by the work of social scientists Jane Jenson and Paul Bernard, to incorporate five domains:
Belonging: Shared values, identification with Australia, trust.
Social justice and equity: Evaluation of national policies.
Participation: Voluntary work, political and cooperative involvement.
Acceptance and rejection, legitimacy: Experience of discrimination, attitudes towards minorities and newcomers.
Worth: Life satisfaction and happiness, future expectations./.../
Regulatory Action on Rosiglitazone by the U.S. FDA
NEJM | September 23, 2010 | Topics: Drugs, Devices, and the FDA
Janet Woodcock, M.D., Joshua M. Sharfstein, M.D., and Margaret Hamburg, M.D.
There have been ongoing concerns about the safety of the diabetes drugs containing rosiglitazone (Avandia, Avandaryl, and Avandamet) — a thiazolidinedione antidiabetic agent indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.
In 2007, a meta-analysis of controlled clinical trials found increases in the risk of myocardial infarction and a near-significant increased risk of death from cardiovascular causes when rosiglitazone was compared with placebo or with standard diabetes drugs.1 Following an advisory committee meeting held in July 2007, the U.S. Food and Drug Administration (FDA) added information about the possibility of ischemic cardiovascular risk to the drug’s existing boxed warning. At the same time, the FDA also required the sponsors to conduct a head-to-head cardiovascular safety trial of rosiglitazone versus pioglitazone — the other antidiabetic drug in this class available in the United States. After new data became available, the FDA held a second advisory committee meeting on rosiglitazone safety on July 13 and 14, 2010. On September 23, 2010, the FDA announced regulatory actions stemming from these deliberations
The case of rosiglitazone underscores the need for a robust evidence base to demonstrate the safety of medicines administered long-term. The FDA is committed to advancing the science of drug safety evaluation, during both drug development and in the postmarketing period.
Editor’s note: The European Medicines Agency also took regulatory action on rosiglitazone on September 23 (www.ema.europa.eu/docs/en_GB/document_library/Press_release/2010/09/WC500096996.pdf).

Medications used to treat neurologic and psychiatric conditions increase smokers’ nicotine metabolism
|Researchers from UMDNJ- Robert Wood Johnson Medical School found carbamazepine and oxycarbamazepine, medications commonly used to treat neurologic and psychiatric conditions, increase nicotine metabolism in smokers.|
As nicotine metabolism increases, cravings for nicotine return more quickly which could lead to more frequent cigarette consumption among individuals who also take these medications.
Study author Jill M. Williams, M.D., an associate professor of psychiatry and director of the Division of Addiction Psychiatry at UMDNJ-Robert Wood Johnson Medical School, said "the effects of these medications may have serious implications on nicotine metabolism and smoking behaviour."
