Missing boy found 13 years later

In August 2002, a five-year-old boy vanished without a trace after his father dropped him off at preschool. Alabama tot Julian Hernandez was in the legal custody of his mother when he disappeared, and while police suspected his father, Bobby Hernandez, kidnapped him as part of a “non-custodial parental abduction”, they were never able to figure out what exactly happened to the little boy.

It wasn’t until 13 years later, when a young man 1100 kilometres away began applying for colleges, that a dark secret was uncovered.

Living under a different name in Cleveland, Ohio, the 18-year-old student realised there was a problem with his social security number when it failed to verify. With the help of the National Centre for Missing and Exploited Children, where they found five-year-old Julian’s profile. The missing little boy was him.

Shoes with high heels are the fashion choice for many women around the world. However, a new study by Stanford University in the USA proves that wearing high heels over a long period of time can permanently injure the body. The study by a biomotion team from the University scanned the knees of healthy women as they walked at a normal pace in flat shoes, 1.5 inch heels and 3.5 inch heels. The results send a warning to women who want to wear high heels that they risk permanent damage to their knees. The researchers found that when women wear high heels, their knees are held in an awkward, bent position causing the joints to perform as though aged or damaged joints would – increasing the risk the condition known as osteoarthritis, which could require surgery.

Britain’s Daily Express newspaper reports a recent survey of 1,200 women that shows how popular high heels are. It said 93 per cent of women felt sexier and more feminine when they wore heels, 88 per cent said they considered themselves more stylish and 77 per cent said their heels made them feel slimmer. Most women prefer to ignore health warnings, and even the pain and discomfort of wearing heels, to look and feel good.

A British doctor, Tim Allardyce, said he regularly treats women with problems caused by wearing heels. “Because of the odd angle at which the feet are held in high-heeled shoes, it increases the downward pressure on the knees by 25 per cent, placing significant stress on the kneecaps, even when you’re standing still,” he explains. He added: “Standing and walking on the balls of your feet throws the skeleton out of its usual, healthy alignment, which means muscles and joints throughout the body have to compensate to maintain its centre of gravity and keep the body upright.”

“'Major' Ketamine Discovery May Lead to New Antidepressants

The possibility of an antidepressant that delivers ketamine's rapid antidepressant effects but none of its potential harms may be one step closer, new research shows.

Investigators at the National Institute of Health (NIMH) have discovered that ketamine rapidly lifts depression via a by-product of its metabolism. This metabolite singularly reversed depression-like behaviors in mice without triggering any of the anesthetic, dissociative, or addictive side effects associated with ketamine.

"This discovery changes our understanding of how this rapid antidepressant mechanism works and holds promise for the development of more robust and safer treatments," study investigator Carlos Zarate, MD, National Institute of Mental Health, Methesda, Maryland, said in a statement."Ketamine is a reasonable option to consider when patients have tried everything else, as long as it's in the right hands and given at the right time," Dr Zarate told Medscape Medical News."But if you had an alternative drug that works rapidly but which doesn't have any risk of addiction or cause any of ketamine's side effects, you open up the possibility of many others being able to receive an alternative to ketamine," he added.

The study, led by Panos Zanos, PhD, University of Maryland School of Medicine, Baltimore, was published online May 4^th in Nature.‖

The Greenhouse Effect

[1] A greenhouse is a house made of glass. The sun shines
right through the glass and makes it warm inside the
greenhouse. It is possible to grow flowers and
vegetables inside a greenhouse in the winter. Scientists
[5] have a theory that a lot of carbon dioxide in the
atmosphere will act like the glass in a greenhouse. As
the sun shines through the carbon dioxide blanket, the
atmosphere will get hotter and hotter.
Carbon dioxide is produced by combustion, the burning
[10] of fuel. It is being added to the normal atmosphere as
we have more and more cars, more and more houses
and industries. In short, more people produce more
carbon dioxide.
Scientists predict that as a result of more carbon dioxide
[15] in the atmosphere, there will be a global warming, or a
long-term rise in temperatures over the earth.

TEXT

A dam from an open-pit mining complex burst on Thursday in southeastern Brazil, flooding a nearby community and enveloping homes and cars in sludge. Rescue teams descending from helicopters scoured the site for survivors.

The authorities said Thursday night that they were trying to determine the number of casualties, with Brazilian news organizations reporting that at least one person had died. Union officials representing workers at the mine said they feared that as many as 15 people might have died after the dam burst.

The episode in a district of Mariana, a city of 58,000 residents in Minas Gerais State, stunned a country that relies heavily on dams to produce electricity and on mining to generate export revenue. The dam operated by Samarco, a venture between BHP Billiton, the Australian commodities giant, and Vale, the Brazilian mining company, held residue from an open-pit iron ore mining operation.

“We need rigor in determining what happened,” Carlos Eduardo Ferreira Pinto, a prosecutor in Minas Gerais, told reporters on Thursday. “No dam bursts by chance.”
