Blood vessels behind eyes are secret to the age of the human brain

first_imgTimes of India: The secret behind the actual age of your brain is inside your eyes.Scientists have found that the width of blood vessels in the retina, located at the back of the eye, may indicate brain health years before the onset of dementia.Retinal blood vessels share similar size, structure, and function with blood vessels in the brain and can provide a way of examining brain health in living humans.Individuals who had wider retinal venules showed evidence of general cognitive deficits, with lower scores on numerous measures of neuropsychological functioning, including verbal comprehension, perceptual reasoning, working memory and executive function.Surprisingly, the data revealed that people who had wider venules at age 38 also had lower IQ in childhood, a full 25 years earlier.Younger people who score low on intelligence tests, such as IQ, tend to be at higher risk for poorer health and shorter lifespan, but factors like socioeconomic status and health behaviours don’t fully account for the relationship.Psychological scientist Idan Shalev of Duke University wondered whether intelligence might serve as a marker indicating the health of the brain, and specifically the health of the system of blood vessels that provides oxygen and nutrients to the brain.Read the whole story: Times of Indialast_img read more

Platts: Libyan Output Drop-Off Hits OPEC’s July Oil Production

first_img[mappress]Press Release, August 9, 2013 Crude oil output from the Organization of the Petroleum Exporting Countries (OPEC) fell 110,000 barrels per day (b/d) to 30.34 million b/d in July from 30.45 million b/d in June, a Platts survey of OPEC and oil industry officials and analysts showed Thursday.“When the consuming world wonders why oil prices remain relatively high, the Libyan production drop-off cited in our report is a reason,” said John Kingston, Platts global director of oil, “as well as the declines seen from South Sudan, Egypt, Syria, and in particular, the decline in Nigeria, though it rose slightly this month.”The key production increases are coming from: the United States, Canada, and swing producer Saudi Arabia.“Ultimately, it’s a lot of heavy lifting for those three countries, given the shortfalls in so many other locations,” Kingston noted.A 130,000 b/d increase from OPEC kingpin Saudi Arabia failed to offset the 200,000 b/d month-over-month crude output drop in Libya, where production and exports have been affected by strikes about pay and conditions as well as protesters demanding oil sector employment. Libyan crude output was estimated at an average 1 million b/d in July.Libya’s main oil export terminals at Es Sider, Ras Lanuf and Zueitina remained closed this week. Prime Minister Ali Zeidan said last week that crude exports had dropped by more than 70% to just 330,000 b/d. Nuri Berruien, head of the National Oil Corporation, told Platts in early August that output had dropped to around 820,000 b/d.Output increases, albeit small, were seen in Kuwait and in Nigeria last month, where the Trans-Niger pipeline briefly came back on stream before being shut down again after a new leak.Output from sanctions-strapped Iran dipped by 20,000 b/d to 2.66 million b/d. Iraqi production fell for the third consecutive month, to 2.98 million b/d in July from 3 million b/d in June, 3.1 million b/d in May and 3.15 million b/d in April. Angolan production fell by 30,000 b/d to 1.75 million b/d.OPEC exceeded its overall production ceiling of 30 million b/d by 340,000 b/d in July. The group agreed at its Vienna meeting in June to maintain the ceiling established in January 2012 but which does not include individual country quotas.last_img read more

One year after this historical event, the Himalayan Mountaineering Institute was established on 4th November 1954 — a result of personal initiative of Pundit Jawaharlal Nehru the first Prime Minister of India and Dr BC Roy the then Chief Minister of West Bengal to promote mountaineering in India. The HMI has trained approximately 40,000 personnel, including 2000 overseas trainees, including many famous mountaineers. Since 1954, the institute organised numerous mountaineering expeditions in the Himalayan regions and overseas, including the Alps under the leadership of institute heads.last_img read more
