While manatees in the United States today are more associated with the state of Florida, a relative of theirs once swam the seas along North America’s Pacific coast. Millions of years ago, the Steller’s sea cow (Hydrodamalis gigas) grazed in the kelp forests along the Northern Pacific Ocean and the Bering Sea. This marine mammal is part of the Sirenia order that includes present-day manatees. It could weigh up to four tons and grow to lengths of 26 to 30 feet—much longer than today’s manatees. It grazed along the Northwest’s mighty kelp forests, which today stretches from Baja California, Mexico up the Pacific coastline to Alaska. The sea cow ate huge quantities of kelp from the upper canopy of kelp forests, which allowed needed sunlight to travel down to the forest’s understory.

What a tangled web we weave. When it comes to the impact of the climate crisis on marine food webs, we apparently have not known the half of it. That's according to a new University of Nevada, Las Vegas (51³Ô¹ÏºÚÁÏ) study, which compared ancient and modern ocean ecosystems in a bid to understand how to make them healthier and more resilient.

Researchers claim they have discovered a rare mineral that comes directly from Earth's lower mantle- the region between the planet's core and crust - in a new study published in Science.

By studying these literal chunks of Mars, scientists are learning more about the Red Planet’s deep interior and impact history.

Nevada is called the Silver State because of the silver mining industry which was a big part of the state’s early history. What’s lesser known is that Nevada can mine for minerals like lithium too, and it could one day become something the state is known for like hospitality and tourism.

Lake Mead is lower than it’s ever been, the result of decades of drought and warmer temperatures caused by climate change. The sinking water levels have revealed a different sort of catastrophe; layers of volcanic ash preserved in stone.

Dropping water levels in Lake Mead have revealed a number of interesting things, from sunken boats to bodies in barrels.

The past decade has seen a paradigm shift in the way the world looks at lighting. Homes, offices and streets have turned off wasteful incandescent lights and fluorescent ones that exposed users and the environment to toxic contamination.

Ramping up renewable energy products will require a range of critical metals. One of these elements, tellurium, is gaining in popularity for use in photovoltaics, or solar panels. As global demand for solar panels continues to increase, so is the need for critical metals like tellurium.

Yet another body has been unveiled by the shrinking drought-stricken Lake Mead, bringing the total to at least six skeletal remains as the nation’s largest reservoir continues to dwindle.
