Nearly three weeks since a 5-month-old pup died of toxic shock after a dip in the Virgin River at Zion National Park, park and health officials are still puzzled how the deadly organisms wound up in the waters.

Global efforts are being made to cut down carbon emissions that cause our planet to warm up. While the efforts are being made in the right direction, scientists warn that we may not see the desired results as soon as we think.

The transition to electric vehicles and renewable sources of electricity, now gaining serious momentum, is largely about dispensing with fossil fuels. But in order to end our reliance on those substances, we need a growing supply of other materials—things like lithium and rare earth elements. Unlike fossil fuels, however, these materials need not be consumed when we put them to use. In principle, devices can be recycled at end of life to return these precious materials to a closed loop that could eventually minimize the need for mining.

The Comet NEOWISE is expected to remain visible to the naked eye through Saturday. Following that, it will be visible with binoculars or a telescope until the end of July.

This week is the best time to see a comet that won’t be visible again for 6,800 years.

Despite the pandemic, NASA is on track to launch its Mars rover, Perseverance, this July from Cape Canaveral, Florida. Its central mission will be to search for evidence of previous life on Mars.

The amount of heat-trapping carbon dioxide in the atmosphere hit a record high in May. That's because humanity kept emitting a prodigious amount of carbon, even through the worst pandemic in a century. But if civilization does begin to significantly cut emissions, global temperatures won't promptly start going down, like flipping a climate switch.

Silver, bug-eyed extraterrestrials zooming across the cosmos in bullet-speed spaceships. Green, oval-faced creatures hiding out in a secret fortress at Nevada’s Area 51 base. Cartoonish, throaty-voiced relatives of Marvin the Martian who don armor and Spartan-style helmets.

If you’ve ever queued on a crowded walkway, sandwiched tightly between two strangers, and thought: ‘There must be a better way to board a plane’, here’s the good news: You’re right. The bad news? Most airlines simply don’t care.
