Repair or replace? This is a difficult choice for consumers when appliances that they own, like TVs and refrigerators, break down. Too often, the only option, or at least the cheaper one, is to replace an appliance rather than get it repaired.
However, a new law in the United Kingdom may help extend the life of some of these larger appliances. It requires manufacturers to make spare parts that consumers can buy to repair their products.
El 11 de marzo de 2011, la costa noreste de Japón fue sacudida por un terremoto de magnitud 9,0, el más grave en la historia del país. En 40 minutos, los temblores siniestros provocaron un tsunami masivo, que arrasó la costa y causó un daño incalculable a la planta nuclear de Fukushima Daiichi.
A raíz de los dos desastres naturales, murieron más de 15.000 personas. Casi medio millón de residentes se vieron obligados a evacuar sus hogares.
Imagínese 5.200 millones de galones de agua moviéndose por segundo, ¡casi 100 veces el caudal del río Amazonas!
La Corriente del Golfo, una poderosa corriente del océano Atlántico, es responsable de este movimiento de agua.
Imagine 5.2 billion gallons of water moving per second -- nearly 100 times the flow of the Amazon River!
The Gulf Stream, a powerful Atlantic ocean current, is responsible for this movement of water.
However, evidence shows that the Gulf Stream is slowing down, and the current is weaker than it has been for thousands of years. Scientists are concerned that it could completely shut down by 2100. This could have devastating implications for climate, sea levels, and extreme weather events. Let’s find out more.
On March 11, 2011, Japan’s northeastern coast was roiled by a magnitude 9.0 earthquake, the most serious in the country’s history.
Within 40 minutes, the ominous tremors triggered a massive tsunami, which washed ashore and caused untold damage to the Fukushima Daiichi nuclear plant.
In the aftermath of the twin natural disasters, more than 15,000 people perished. Nearly half a million residents were forced to evacuate their homes.
La sabiduría viene con la edad, dice el viejo refrán. Y Wisdom, el albatros de Laysan, lo prueba. Tiene 70 años, vive en estado salvaje y está llena de sorpresas.
Etiquetado por primera vez en 1956, Wisdom se ha vuelto muy especial para los amantes de las aves de todo el mundo. Su larga vida ha remodelado nuestro conocimiento sobre los albatros y su comportamiento. A lo largo de los años, ha sobrevivido a sus compañeros y ha criado a casi 36 polluelos.
Cuando Jamie Hill vio una fotografía de un cardenal de aspecto peculiar, primero pensó que había perdido pigmentación (color de piel) en algunas de sus plumas.
Hace cuarenta y dos mil años, nuestra Tierra no se parecía en nada a lo que es hoy.
Los vientos solares provocaron deslumbrantes despliegues de luces en los polos de nuestro planeta, tormentas eléctricas arrasaron los continentes y la radiación cósmica llenó la atmósfera, todo gracias a un giro del campo magnético de la Tierra.
Wisdom comes with age, goes the age-old saying. And Wisdom, the Laysan albatross, proves it. She is 70 years old, lives in the wild, and is full of surprises.
First tagged in 1956, Wisdom has since become very special to bird-lovers everywhere. Her long life has reshaped our knowledge of albatross and their behavior. Over the years, she has outlived mates and raised nearly 36 chicks.
On February 1, Wisdom and her current mate welcomed their newest chick at the world’s largest albatross colony in Midway Atoll, Hawaii.
The Albatross
Forty-two thousand years ago, our Earth looked nothing like it does today.
Solar winds caused dazzling displays of lights at our planet’s poles, electrical storms raged across the continents, and cosmic radiation filled the atmosphere -- all thanks to a flip of the Earth's magnetic field.
