Sea creatures store carbon in the ocean – could protecting them help slow climate change?

Heidi Pearson, University of Alaska Southeast

As the prospect of catastrophic effects from climate change becomes increasingly likely, a search is on for innovative ways to reduce the risks. One potentially powerful and low-cost strategy is to recognize and protect natural carbon sinks – places and processes that store carbon, keeping it out of Earth’s atmosphere.

Is Cloning the Future of Genomics?

Almost every human condition can be linked back to your genes. The list of genetic conditions is lengthy. Diseases like muscular dystrophy, Crohn’s disease, birth defects like spina bifida, and some cancers just barely scrape the long list of ailments that can be passed from one generation to the next. And, it seems that many of us try to overcome our genetics at every opportunity. We work to live a healthy lifestyle, eat the right foods, limit stress, and get enough rest each day. What if there was a better way to protect yourself and those you love from your own genes?

Humans walking on two legs because of exploding stars, new study says

Walking on two legs is an evolutionary leap that led humans to conquer the world. But, why humans are walking on two legs? It’s still unclear. Now, according to a new study published on the University of Chicago’s Journal of Geology, the reason might be exploding stars a few million years ago.

8 Things that make Life on Earth Possible

Earth, our blue planet is an oasis in the vast, cold, and dark space. It is the only planet we know of that can support life. The fossil record tells us that life on Earth has lasted at least 3.5 billion years (the Earth is about 4.54 billion years old), with the oldest physical traces of life dating back 3.7 billion years. And, if some kind of disaster doesn’t intervene, our planet should continue to host life for at least another 1.75 billion years. Here are the 8 things that make life on Earth possible.

Tragic tale of a ‘man-eating’ tigress tells us so much about the climate crisis

Nayanika Mathur, University of Oxford

The way that we live on Earth is causing an unprecedented acceleration in species extinction. Now, more than half a million species “have insufficient habitat for long-term survival” and are likely to go extinct unless their natural environments are restored. But we are already seeing major problems from this intrusion, not least through an increase in human-animal conflict.

Top 10 Largest Crocodiles Ever Recorded

Although crocodiles are really large reptiles and can get enormous sizes, they suffer from a prevalence of “big fish” stories and over-exaggeration. In the Internet age, photographs of crocodiles often manipulated digitally to make the animal look much larger than it is. So, how big the largest crocodiles are actually? Here are the top 10 largest crocodiles ever recorded.

UN report warns one million species at risk of extinction

We, humans, are destroying the Earth’s wilderness, very fast. Actually, we are the main (and probably the only) cause of the sixth major extinction event in the history of our planet. Now, a recent UN report says at least one million species (animals, plants, and insects) are at the risk of extinction. There will be serious consequences for life on Earth, and also for human beings.

Two neutron stars collided near the solar system 4.6 billion years ago

According to a new study published in the May 2, 2019 issue of Nature, 4.6 billion years ago, two neutron stars collided near the early Solar System (actually about 1000 light years from the gas cloud that eventually formed the Solar System). This violent collision has created heavy elements like silver, gold, platinum, cesium, and uranium. Study says 0.3% of the Earth’s heaviest elements have been created by this event.
