The Intermountain Bird Observatory was keeping tabs on them, and was receiving reports of up to 60 spending the winter here each year.And there’s perhaps no better way to discover those birds than by keeping a yard list.

Over the years, Cool Green Science has covered many wildlife activities that can be enjoyed in a backyard, a city park or a vacant lot.While scavenger hunts don’t have to involve nature, the challenge of finding plants and animals makes for a more rewarding quest.

A new international study using ancient swamp kauri from Northland shows a temporary breakdown of Earth’s magnetic field 42,000 years ago sparked major climate shifts leading to global environmental change and mass extinctions.

Recently, Genge has been interpreting messages the space dust carries, not about its origins, but about its destination: Earth at different points in the planet’s history.

The scene suggests that Nathan imbued his robot creation with disco functionality, but how did he choreograph the dance on Kyoko, and why?.When roboticists work choreographically to determine robot behaviors, they’re making decisions about how human and inhuman bodies move expressively in the intimate context of one another.

Late last year, during the Fox broadcast of a matchup between the Seattle Seahawks and the Washington Football Team, fans were treated to shots of end zone celebrations that felt ethereal, almost dreamlike.

It’s a dramatic departure from how a hardware developer like Boston Dynamics goes about teaching a robot how to move , using decades of human experience to hard code, line by line, the way a robot is supposed to react to stimuli like, um, a person’s foot.

A few years later, he found himself working on the front lines of the young field’s marquee moon shot: the Human Genome Project.Eric Green: I was inside the Human Genome Project from day one, and I can’t stress enough how back then we didn’t know what we were doing.

But while thousands of life scientists pivoted to trying to understand how the novel coronavirus wreaks havoc on the human body, and others transformed their labs into pop-up testing facilities, the field of Crispr gene editing nevertheless persisted.

This book tells stories of restoration at all scales, “from a small plot between sidewalk and curb to areas large enough to be labeled on a world map.” She spends time with people who, faced with seemingly insurmountable challenges, look to nature for solutions.

Neutron stars are best known for powering pulsars, rapidly repeating bursts of radiation driven by the fact that these massive objects can complete a rotation in a handful of milliseconds.

Among those to receive this Wikipedia boost in the past was a candidate named Joni Ernst, whose page received 13,000 views just before Election Day in 2014.

To theorists puzzling over the physical meaning of renormalization, QED hinted that the electron had two charges: a theoretical charge, which was infinite, and the measured charge, which was not.

Unless you are medically vulnerable, or your doctor or local public health official thinks it’s a good idea, the new guidance states, “you do not necessarily need a test.” Previously, the agency had recommended testing for anyone with a “recent known or suspected exposure” to the virus, and CDC director Robert Redfield said in an interview with NBC last month that “anyone who thinks they may be infected—independent of symptoms—should get a test.”.

“There’s a lot of uncertainty in the whole field as to whether [Neuralink] is ever going to be successful,” says Sid Kouider, a former neuroscientist at the French National Centre for Scientific Research, who has since started his own neural interface startup, NextMind.

With the landfall comes a dreaded storm surge—a rise in water level generated by a storm—that scientists say could spread seawater up to 30 miles inland, an inundation the National Hurricane Center just called “unsurvivable.”.

Given that she infects ant colonies with deadly pathogens and then studies how they respond, one might say that Nathalie Stroeymeyt, a senior lecturer in the school of biological sciences at the University of Bristol in the U.K., specializes in miniature pandemics.

During World War I, this stretch of pastoral landscape, which the generals (and now historians) called the Ypres Salient, was one of the most heavily trenched, mined, mortared, bombed, gassed, pillaged, burned, and bullet-riddled places along the Western Front.

As the authors note in the paper, “Only 0.2% of ingested eggs survived gut passage, yet, given the abundance, diet, and movements of ducks in nature, our results have major implications for biodiversity conservation and invasion dynamics in freshwater ecosystems.”.

In a paper posted online in April and under review with Physical Review Letters, the cosmologists Karsten Jedamzik and Levon Pogosian argue that weak magnetic fields in the early universe would lead to the faster cosmic expansion rate seen today.

And if you’re looking for more, Cool Green Science has abundant reviews on a variety of topics, from nature in literary fiction and mystery novels, books for birders and for anglers and traveling naturalists , reviews of field guides and nature references , and much more.

Images place us in time, gluing unremarkable and historically urgent moments in a fixed setting or context, but mostly they thrill our senses in other varied ways.Photographer Stephen Maturen’s snapshot of a young black protester—on his knees and shirtless, hands raised like a goal post—is an image of staggering breadth.

You may never draw as beautifully as Clare Walker Leslie or John Muir Laws, whose nature journals are exquisite, or be as technically accurate as a scientist recording field notes for rigorous studies, but you don’t have to be.

Another study of English and German soccer league games played in full stadiums found that referees have a subconscious bias toward the home team.In Germany, where some stadiums have running tracks that separate the fans from the soccer field, Simmons also found that referees issued fewer fouls to visiting teams.

I moved in March, so I spent my first week of lockdown unpacking boxes and starting a new yard list .I even managed to see the Spotted Gars spawning; something I’ve only observed three times in 20 years of studying these ancient fish!

The elder McMichael is a former investigator who worked with the Brunswick district attorney’s office, which was one of the reasons two prosecutors recused themselves from the case, slowing the process, although I have a hard time believing other racially rooted factors were not at play.

In 1933, Peterson convinced Houghton Mifflin to publish a Field Guide to the Birds as a new way to identify our feathered friends.Identifying nature is fun, but what I love most about field guides is that the change the way you see .

As Mesplé pushed his experiments with ferrofluids further, he found himself wanting the stuff to jump distances, as it does by flowing into the Killing Time skull’s mouth.Like that one time Mesplé tested a particularly powerful magnet with a crescent wrench.

In Peru, that kind of work, maps combined with demographic data, will help the government get cash—around $107 (US)—to those quarantined near Cusco.“Buildings and roads aren't visible on the map yet, but you can see them really clearly in satellite imagery,” says Firth.

In the 1970s, when physicists first worked out the standard model of particle physics—the still reigning set of equations describing the known elementary particles and their interactions—they sought some deep principle that would explain why three generations of each type of matter particle exist.
