Staring straight into the eye of a monster

By Tom Yulsman | September 12, 2018 8:06 pm

As Florence swirled toward the Carolinas today, an astronaut took some chilling photos of the hurricane

“Ever stared down the gaping eye of a category 4 hurricane? It’s chilling, even from space.”

So writes Alexander Gerst, a European Space Agency astronaut aboard the International Space Station who shot this stunning photo looking straight down into the eye of fearsome Hurricane Florence.

As of 5 p.m. EDT on Wednesday, the hurricane was bearing down on Carolina coastal areas with m …

A Simple Blood Test Could Tell You the Time Inside Your Body

By Rosemary Braun, Northwestern University | September 12, 2018 2:40 pm

In life, timing is everything.

Your body’s internal clock – the circadian rhythm – regulates an enormous variety of processes: when you sleep and wake, when you’re hungry, when you’re most productive. Given its palpable effect on so much of our lives, it’s not surprising that it has an enormous impact on our health as well. Researchers have linked circadian health to the risk of diabetes, cardiovascular disease and neurodegeneration. It’s also known that the timing of meals  …

What is the Evidence for Hurricanes in the Distant Past?

By Erik Klemetti | September 12, 2018 9:04 am

Hurricanes are massive meteorological events and, as we’ve seen recently in Puerto Rico, enormous humanitarian disasters. Yet, on a geologic timescale, massive storms like hurricanes and typhoons are ephemeral moments that are surprisingly difficult to read in the rock record, even if they seem like such powerful forces when they occur. Right now, Hurricane Florence is bearing down on the  Carolinas and it makes me wonder, what evidence could we expect to find for the hurricane 100, 1,000 …

Pigeon Poop And Strange Static: How We Proved The Big Bang

By Korey Haynes | September 11, 2018 3:00 pm

Sometimes scientific discoveries are made in world-class laboratories, when brilliant scientists come together to prove a wonderful idea true with fresh experiments. And sometimes, the secrets of the universe are hidden under a pile of pigeon poop.

And so it happened that the first observation of the crackle of nascent energy left over from the Big Bang was not some long-sought holy grail of science. Instead, it was an annoying bit of static mistaken for bird droppings. Such is the lofty  …

Feasting off unusually warm sea surface waters, Hurricane Florence has exploded in strength

By Tom Yulsman | September 10, 2018 7:09 pm

National Hurricane Center: “Unfortunately, the models were right”

When I woke up this morning, Hurricane Florence was a Category 1 storm with maximum sustained winds a little above 100 miles per hour. As the storm has moved over very warm waters during the day, it has exploded in intensity to a Category 4 storm with max winds of 140 miles per hour.

As the National Hurricane Center put it this afternoon:
Unfortunately, the models were right. Florence has rapidly intensified into a …

Technology Aims to Bring Us Longer Lives. How Ethical is That?

By John K. Davis | September 10, 2018 2:07 pm

Life extension – using science to slow or halt human aging so that people live far longer than they do naturally – may one day be possible.

Big business is taking this possibility seriously. In 2013 Google founded a company called Calico to develop life extension methods, and Silicon Valley billionaires Jeff Bezos and Peter Thiel have invested in Unity Biotechnology, which has a market cap of US$700 million. Unity Biotechnology focuses mainly on preventing age-related diseases, but …

Watch as Florence blossoms from a tropical storm to a hurricane that now poses life-threatening impacts

By Tom Yulsman | September 10, 2018 10:12 am

An animation of amazingly detailed satellite imagery shows Florence strengthening and heading toward the U.S. East Coast

After blossoming into a hurricane yesterday, Florence strengthened further overnight into a Category 3 storm this morning with maximum sustained winds of 115 miles per hour.

Feasting off the energy from unusually strong sea surface temperatures, Hurricane Florence is intensifying quickly and tracking inexorably toward landfall along the U.S. Southeast or Mid- …

When is it OK For Archaeologists to Dig Up the Dead?

By Bridget Alex | September 7, 2018 5:00 pm

Banana was code for human bones, on one archaeological dig where I’ve worked. We were excavating a cemetery, several thousand years old, and had permits from the appropriate authorities. However, certain religious groups in the area had a history of protesting any destruction of burials, so we kept our work discrete.

We packed excavated skeletons in boxes labeled “bananas” and referenced the fruit when discussing the project in public.

Our team had legal approval and scientific  …
