Man Rides a Bike on a Rope

Domingo, 1 Octubre 2017

Mountain bike trials is a discipline of mountain biking in which the rider attempts to pass through an obstacle course without setting foot to ground. Belgian mountain bike trials cyclist and world champion Kenny Belaey managed to bike across a sackline 120-metres above the ground while suspended between two mountains in the French Alps.

His first attempt at crossing the stomach-churning course was not successful, but he had another try with his safety harness.

A girl was found living among monkeys in an Indian forest. How she got there is a mystery.

Viernes, 7 Abril 2017

Amid a troop of monkeys in the Katraniaghat forest range in northern India roamed a naked human girl, playing with the primates as if she were one of them. She looked emaciated, her hair disheveled. But she appeared to be in a comfortable state, until the police arrived.

A group of woodcutters had alerted authorities after spotting the girl, believed to be 10 to 12 years old. When police approached her, the monkeys surrounded the girl, protecting her as one of their own, and attacking an officer as the girl screeched at him. After rescuing the girl, the officer sped away in his patrol car, the monkeys chasing him.

She was soon admitted to a state-run hospital in Bahraich, a city in the northern Indian state of Uttar Pradesh, where she has remained for the past two months. Doctors believe the girl had been raised by monkeys for quite some time, and her story has so far mystified authorities, sending them searching through reports of missing children in an attempt to identify her.

In the Indian press, the girl has also drawn comparisons to Rudyard Kipling’s Mowgli, a child from Seoni, India, featured as the prominent character in Kipling’s “The Jungle Book.”

Based on her behavior, it appears she could have lived among the primates since she was an infant. When the girl arrived at the hospital, she had wounds all over her body.

The thin, weak girl looked like she had not eaten for many days. Although she was capable of walking on her feet, she would sometimes suddenly drop down on all fours.

The way she moved, even her eating habits were like that of an animal. She would throw food on the ground and eat it directly with her mouth, without lifting it with her hands. She used to move around using only her elbows and her knees.

Now, doctors are tasked with teaching her how to transition to life as a human, a task that initially proved difficult because of her aversion to human interaction.

She behaves like an ape and screams loudly if doctors try to reach out to her. Another doctor treating her said the girl struggles to understand anything, and makes apelike noises and facial expressions.

But over the past two months, the girl’s health and behavior have improved significantly, doctors say. She has begun to walk normally by herself and eat food with her own hands. She is still unable to speak, and has begun to use gestures to communicate. Occasionally, she smiles.

Introducing Zealandia

Scientists think New Zealand might be part of a lost underwater continent.

New Zealand is made up of many small islands, but geologists say they’re all connected by one underwater continent.

A group of geologists believes New Zealand and several surrounding islands, including New Caledonia, should be reclassified as part of an eighth continent called Zealandia. The archipelago, or group of islands, is currently grouped with Australia in the Australasia region. But scientists think there is enough geological evidence to give New Zealand its own continent designation.

The islands are connected by submerged continental crust. That crust, or outermost layer of earth, is separate and distinct from Australia and Antarctica. About 94% of that 1.9 million-square-mile land mass  is underwater. Still, the geologists argue that the area should count as its own continent.

The geologists spent more than two decades gathering enough data to make the case for Zealandia.

They argue that if Earth’s surface was mapped the way other planets have been—that is, without massive oceans to obscure landforms - Zealandia would long ago have been recognized as a continent.

Indian children died after eating lychees on empty stomach

USA and Indian scientists say a mystery illness that killed more than 100 children a year in northern India was caused by eating lychees on an empty stomach.

For more than two decades, apparently healthy children in a region of Bihar suffered sudden seizures and lost consciousness.

Almost half died, baffling doctors.

New research now suggests they were poisoned by the fruit.

Hypoglycin

Most of the victims were poor children in India’s main lychee-producing region who ate fruit that had fallen on to the ground in orchards, the journal said.

Lychees contain toxins that inhibit the body’s ability to produce glucose, which affected young children whose blood sugar levels were already low because they were not eating dinner.

They woke screaming in the night before suffering convulsions and losing consciousness as they suffered acute swelling of the brain.

Researchers examining sick children admitted to hospital in Muzaffarpur between May and July 2014 found a link to an outbreak of sickness that caused brain swelling and convulsions in children in the Caribbean.

That outbreak was caused by the ackee fruit, which contained hypoglycin, a toxin that prevents the body from making glucose. Tests then showed that lychees also contained hypoglycin.

This led health officials to tell parents to make sure young children got an evening meal and limit the number of lychees they were eating.

Children suffering symptoms associated with the outbreak should be rapidly treated for hypoglycaemia, or low blood sugar, officials said.

The number of reported cases of the sickness has since fallen from hundreds each year to about 50.

Swedish Taxi-pod

Students in Goteborg’s busy city centre do not need to take a bus or a traditional cab to travel through the city anymore. They can use a new service – a Taxi-pod, a three-wheeled yellow slightly miniature and battery-powered car.

The company Burst was founded in November 2014 with the idea to beat traffic. The idea is to solve the problem for traffic in centres in big cities. The company would like to provide a perfect service for short trips within the city from A to B. The idea is also to reduce vehicle emissions in central areas.

People using the bus travel probably for longer distances, they do not need to be in a hurry, and they do not need to get straight to their final destination. But for lots of people, traveling quickly is very important.

However, it is not just speed that concerns the makers of these cars, but improving the quality of air. They see a huge potential for solving congestion problems and problems with air quality in pretty much all cities across the globe.

One of the passengers finds that the Taxi-pods are environmentally friendly, cheap, easy to get by in the city and fun.

What is glass?

Jueves, 2 Junio 2016

Believe it or not, glass is made from liquid sand. You can make glass by heating ordinary sand (which is mostly made of silicon dioxide) until it melts and turns into a liquid. You won’t find that happening on your local beach: sand melts at the incredibly high temperature of 1700°C (3090°F).

When molten sand cools, it doesn’t turn back into the gritty yellow stuff you started out with: it undergoes a complete transformation and gains an entirely different inner structure. But it doesn’t matter how much you cool the sand, it never quite sets into a solid. Instead, it becomes a kind of frozen liquid or what materials scientists refer to as an amorphous solid. It’s like a cross between a solid and a liquid with some of the crystalline order of a solid and some of the molecular randomness of a liquid.

Glass is such a popular material in our homes because it has all kinds of really useful properties. Apart from being transparent, it’s inexpensive to make, easy to shape when it’s molten, reasonably resistant to heat when it’s set, chemically inert (so a glass jar doesn’t react with the things you put inside it), and it can be recycled any number of times.
