Last month was the fourth warmest May on record, two reports out today agree

By Tom Yulsman | June 18, 2018 1:54 pm

In their monthly climate reports released today, both NASA and NOAA agree that last month was fourth warmest among all Mays dating back to 1800.

This means that the period 2014 through 2018 has brought the five warmest Mays in 138 years of record-keeping, according to NOAA’s report. The warmest was May 2016.

“May 2018 also marks the 42nd consecutive May and the 401st consecutive month with temperatures, at least nominally, above the 20th century average,” according to NOAA.

Vote for Groups C and D in the Geology World Cup

By Erik Klemetti | June 18, 2018 10:17 am

I’ll have another post later today with some of the geology news of the weekend, including the eruptions in Kīlauea and Fernandina, along with the earthquake in Japan. However, first I’ll give everyone a chance to vote for Groups C and D in the Geology World Cup. If you haven’t voted in Group A or Group B, do it!

Group C

Australia: The only country that is also a whole continent, Australia also boasts the oldest crystals on Earth – the ~4.4 billion-year-old Jack Hills zircon. Off its  …

Happy National Pollinator Week!

By lshell | June 18, 2018 9:13 am

From June 18 to June 24 we celebrate the pollinators that make most of our food possible. This week, take a moment to make and share your observations with scientists. Our editors selected five projects in need of your help. More about pollinators from Penn State’s website:


“Pollinators include bees, butterflies, beetles, flies, some birds and some bats. They move pollen from male structures (anthers) of flowers to the female structure (stigma) of the same plant species …



Ayahuasca, the Psychedelic Antidepressant?

By Neuroskeptic | June 17, 2018 6:09 am

A traditional Amazonian psychedelic brew is an effective and rapid-acting antidepressant, according to a paper just published. But the new study revives some long-standing questions.

Ayahuasca is a mixture of herbs, traditionally used for spiritual and therapeutic purposes. The main active ingredients are N,N-DMT, a potent psychedelic, and several molecules that inhibit the enzyme MAO. The MAO inhibitors serve to prevent the N,N-DMT from being broken down by the digestive system, allowing …

El Niño is gestating in the Pacific, possibly heralding warmer global temps and extreme weather in 2019

By Tom Yulsman | June 15, 2018 5:17 pm

While 2019 is still a long way off, we’ve now got some strong hints that the coming year could bring even warmer global temperatures, plus droughts in some regions, and floods in others.

These climatic and weather effects would come from an El Niño that seems to be gestating in the tropical Pacific.

A warming of tropical Pacific waters beneath the surface, along with the output of computer and statistical modeling, have prompted the National Oceanic and Atmospheric Administration to  …

Science Festivals: Report from the Front Lines

By cnickerson | June 15, 2018 3:10 pm

By Caroline Nickerson

Over the past few months, members of the SciStarter team have been working around the country to share new citizen science projects at science festivals. It’s been so much fun to join others excited about science and get a chance to meet some of you!

Organizing a science festival is a labor of love, fueled by the passion of the coordinators, exhibitors, and participants.

The Cambridge Science Festival was one of the first of its kind in the United States. Ma …

To Avoid Humans, More Wildlife Now Work the Night Shift

By Kaitlyn Gaynor, University of California, Berkeley | June 15, 2018 11:46 am

For their first 100 million years on planet Earth, our mammal ancestors relied on the cover of darkness to escape their dinosaur predators and competitors. Only after the meteor-induced mass extinction of dinosaurs 66 million years ago could these nocturnal mammals explore the many wondrous opportunities available in the light of day.

Fast forward to the present, and the honeymoon in the sun may be over for mammals. They’re increasingly returning to the protection of night to avoid the  …

How Can a Baby Have 3 Parents?

By Jennifer Barfield, Colorado State University | June 15, 2018 11:21 am

It seems impossible, right? We have been taught from the time we were young that babies are made when a sperm and an egg come together, and the DNA from these two cells combine to make a unique individual with half the DNA from the mother and half from the father. So how can there be a third person involved in this process?

To understand the idea of three-parent babies, we have to talk about DNA. Most people are familiar with the double helix-style DNA which make up the 23 pairs of chromo …

Vote in Group B of the 2018 Geology World Cup

By Erik Klemetti | June 15, 2018 8:53 am

Yesterday, we started the 2018 Geology World Cup with voting for Group A, so let’s move to the next group!

Group B

Morocco: Much of Morocco’s geology is linked with the slow collision of Africa and Europe. The Atlas Mountains rise up on the western side of Africa and represent the the stresses put on the two plates by Africa plowing into Europe over the last 65 million years. The mountain range that pre-dated the Atlas Mountains (called oddly enough the “Anti-Atlas”) were formed in the …

Seriously, Science?

Flashback Friday: Bumblebees detect electric fields with their body hair.

By Seriously Science | June 15, 2018 6:00 am

We’ve already covered some of the amazing things that bees can do, from making perfectly hexagonal honeycombs to doing “the wave” to scare off predators. And it turns out they even have the power to detect electric fields! Although it was known that bees can detect electric fields around flowers, how they achieve this amazing feat was a mystery… until now! According to these scientists, bees are actually covered with small hairs that respond to electricity. Be sure to check out the video …
