¿Te imaginas cantando la misma canción durante milenios?

Un estudio reciente sobre los pájaros del sol de África Oriental sugiere que estas vibrantes aves han estado haciendo precisamente eso.

Este descubrimiento es una sorpresa para los biólogos. Los pájaros jóvenes aprenden mucho de la misma manera que nosotros aprendemos a hablar. A través del mimetismo, imitan los sonidos de otras aves a su alrededor. Sin embargo, a lo largo de generaciones, las aves a menudo llegan a desarrollar sus propias canciones únicas.

Do you love collecting seashells when you go to a beach? Well, you may need to think twice in the future. 

Mauritius, an island country located east of Africa, is facing a shocking dilemma: there are now fewer seashells on its sandy beaches.

Shells such as the Monetaria annulus, a species of sea snails whose shells are adorned with a gold ring, and the Monetaria moneta, also known as money cowrie, are now much harder to find than before. 

Did you know that nearly 1.8 million homes in the U.S. use wood chips or wood pellets for heating?

These organic materials from plants and trees are known as biomass and are considered renewable sources of energy. 

But are they really as green as they claim to be? We look at the controversy and both sides of the argument. 

What might you expect to find at the bottom of the Antarctic ocean? Surely not an icefish breeding ground twice the size of Paris!

The breeding ground was discovered in February 2021, but the findings were only published recently. Located in the Weddell Sea, the colony stretched across 92 square miles of the ocean floor. Using a remotely operated camera and several dives, researchers concluded there are over 60 million active nests.

Did you know that seven of the hottest years in recorded history have been the last seven years?

This was confirmed recently by the EU's Copernicus Climate Service. In fact, 2021 was the fifth hottest as evidenced by the devastating flash floods, wildfires in the west, and hurricanes in the east. Ocean heat also set record high temperatures in 2021.

Let’s take a look at how this report is connected with our actions, the science of atmospheric heat, and its interplay with the mechanisms of our planet.

Hydropower dams, or dams that produce electricity from water, are sources of renewable energy that are considered good for the environment.

However, the recent destruction of a hydro dam in Norway reveals that sometimes these ‘green’ dams can have a negative impact on ecosystems.

A campaign by fisher Tore Solbakken and 120 other members of a Norwegian angling club urged the Norwegian government to destroy the dam in order to restore local fish populations to their ecosystems. 

What do makeup, toothpaste, and chocolate have in common?

If you guessed palm oil, you’d be correct! This creamy, odorless oil can be found in countless products we use and foods we eat in our daily lives. In fact, we consume close to 70 million tons of palm oil every year!

Can you imagine singing the same song for millennia?

A recent study on East African sunbirds suggests that these vibrant birds have been doing just that.

This discovery comes as a surprise for biologists. Young birds learn much in the same way we learn to speak. Through mimicry, they imitate the sounds of other birds around them. Over generations, however, birds often come to develop their own unique songs.

Why have the sunbirds stuck to the same tunes? Let’s find out.

A mediados de diciembre, seis supermercados anunciaron una decisión conjunta de dejar de vender carne vacuna procedente de Brasil. La razón: los productos de carne de res provenían de ganado criado en áreas deforestadas ilegalmente.

La misma empresa responsable de los productos de res, JBS, también está vinculada al cuero vendido a empresas que fabrican bolsos y zapatos.

Una pequeña ciudad de 30.000 habitantes se convertirá en la primera de Estados Unidos en reducir sus emisiones de carbono.

A principios de noviembre, Ithaca, Nueva York, votó para descarbonizar el 100 % de sus edificios para 2030. La descarbonización implica reemplazar las fuentes de energía que utilizan combustibles fósiles con fuentes renovables para alimentar la ciudad.

Este es un plan ambicioso, especialmente cuando el mundo espera alcanzar cero emisiones de carbono solo para 2050. ¿Cómo planea Ithaca lograr este objetivo?
