The Value of Audience Attention: What Happens Before the Conversion

What do people pay attention to before the conversion happens? Marketers care a lot about conversion and can get caught up in this metric.

eMarketer is pleased to moderate a special presentation with Clare Carr, vice president of marketing at Parse.ly. This webinar will offer insights and best practices to help marketers understand what people are actually paying attention to, enough to convert, so they can replicate it.

Join this live, interactive webinar to learn:
  • What types of content drives the most engagement
  • Where your audience consumes content and what topics they pay attention to most
  • And… case studies from Hello Fresh and MLB!
Please reserve your seat today. Our Tech-Talk Tuesday will take place on Tuesday, June 12, at 1:00 PM ET. We hope you can attend, but if you sign up and can't make it we'll send you a link to view the deck and the recording the day after the webinar.

Bigravity: A Hidden 'Gear' for Gravity?

Yuen Yiu, Inside Science

Two physicists from Montana State University in Bozeman propose a way to test an existing theory of gravity where a hidden "gear" may explain the mystery of dark energy -- an unknown substance that makes up 70 percent of our universe. The paper, published in Classical and Quantum Gravity, suggests that astronomers may be able to test models of bigravity -- a theory in which there are two different components of gravity, as suggested by its prefix -- using X-ray, radio and gravitational wave measurements of neutron stars.

Galaxy Simulations Are Finally Matching Reality

Adrian Cho, Science Magazine

Philip Hopkins, a theoretical astrophysicist at the California Institute of Technology in Pasadena, likes to prank his colleagues. An expert in simulating the formation of galaxies, Hopkins sometimes begins his talks by projecting images of his creations next to photos of real galaxies and defying his audience to tell them apart. "We can even trick astronomers," says Hopkins, a leader of FIRE, the Feedback in Realistic Environments simulation. "Of course, it's not a guarantee that the models are accurate, but it's sort of a gut check that you're on the right track."

Middleweight Black Holes Could Explain Huge Ones

Daniel Clery, Science Mag

How did giant black holes grow so big? Astronomers have long had evidence of baby black holes with masses of no more than tens of suns, and of million or billionsolar-mass behemoths lurking at the centers of galaxies. But middle-size ones, with thousands or tens of thousands of solar masses, seemed to be missing.

How Aliens Might Handle Environmental Collapse

Adam Frank, The Atlantic

The universe does many things. It makes galaxies, comets, black holes, neutron stars, and a whole mess more. We've lately discovered that it makes a great deal of planets, but it's not clear whether it regularly makes energy-hungry civilizations, nor is it clear whether such civilizations inevitably drive their planets into climate change.

Archaeologists Map a Hidden Roman City

Raja & Lichtenberger, ScienceNordic

How do you study ancient cities when they're hidden from view, covered with hundreds or thousands of years of human development by the growth of towns and cities?For archaeologists like us, it's a constant dilemma.Recently, we joined forces with archaeologists and geoscientists in Denmark and Germany to tackle this challenge.

The Main Purpose of the Brain Is to Make Predictions

Kevin Casey, Horizon

Our brains make sense of the world by predicting what we will see and then updating these predictions as the situation demands, according to Lars Muckli, professor of neuroscience at the Centre for Cognitive Neuroimaging in Glasgow, Scotland. He says that this predictive processing framework theory is as important to brain science as evolution is to biology.

Studies on Universal Basic Income Get Rolling

Carrie Arnold, Nature News

Along the shores of Lake Victoria in western Kenya, mobile phones in several hundred villages ding in unison on the first of every month. For more than 21,000 adults, the sound means one thing: 2,250 Kenyan shillings appearing in their bank accounts. The cash equals one-quarter to half of the average income for a two-adult household in Bomet County, one of the poorest in Kenya.

Does Dark Matter Ever Die?

Kate Becker, PBS NOVA

Dark matter is the unseen hand that fashions the universe. It decides where galaxies will form and where they won't. Its gravity binds stars into galaxies and galaxies into galaxy clusters. And when two galaxies merge, dark matter is there, sculpting the product of the merger. But as for what dark matter actually is? No one knows.

Fossil Pushes Origins of Lizards Back 75 Million Years

Belinda Smith, ABC Sci

Based on a small fossil found in the Italian Alps, these ancient reptiles appear to have survived a mass extinction that wiped out more than 90 per cent of all species.The fossilised creature called Megachirella wachtleri isn't a direct relative of modern snakes and lizards, although they shared a common ancestor that scampered around 260 million years ago.

Japan Killed 112 Pregnant Whales for 'Science'

Brigit Katz, Smithsonian

Japan is facing heated criticism from conservationists after a report revealed that its whaling vessels killed 333 Antarctic minke whales in the Southern Ocean last summer, purportedly for the sake of scientific research. According to Lorraine Chow of EcoWatch, 122 of the slain whales were pregnant and 114 were immature.

How Close Are We to a Real Quantum Computer?

Larry Greenemeier, Sci American

The race is on to build the world's first meaningful quantum computerone that can deliver the technology's long-promised ability to help scientists do things like develop miraculous new materials, encrypt data with near-perfect security and accurately predict how Earth's climate will change.

What Politics and Religion Could Learn from Science

William Saletan, Slate

Over my years as a journalist, I've written about many intractable problems: international conflicts, environmental crises, and culture wars. People have slaughtered one another for worshiping the wrong deity. The world's most powerful country has fallen into the grip of a sociopath. So it kills me when scientists and science journalists fret that science is broken.

One of Pompeii's Victims Had a Brutal Death

David Bressan, Forbes

The first human remains in Pompeii were discovered in April 1748. In the following centuries, more human and animal bones have been found, preserved in the volcanic deposits of the disastrous 79 AD eruption of Mount Vesuvius. More than 1,150 victims have been excavated in the ruins of the former Roman city so far, with some hundreds of other remains of bodies that were discovered but later lost.

The Challenges of Human Reproduction on Mars

Brandon Specktor, Live Science

In 1972, citizen scientist Sir Elton John hypothesized that Mars "ain't the kind of place to raise your kids."While John's remarks were never published in a peer-reviewed journal (though they did peak at No. 2 on the UK Singles Chart), he's not wrong about the Red Planet's inhospitality. With its freezing climate, thin atmosphere and weak gravity, Mars will be a hard place to raise the children necessary to sustain a permanent colony there.

Was Elon Musk Right to Call 'BS' on Nanotech?

Andrew Maynard, The Conversation

In case you missed it, Elon Musk called BS on the field of nanotechnology last week. The ensuing Twitter spat was admittedly rather small on the grand scale of things.But it did throw up an important question: just what is nanotech, and where does the BS end and the science begin?

Genetic Intelligence Tests Are Next to Worthless

Carl Zimmer, The Atlantic

In 2016, I got my genome sequenced while I was working on a book about heredity. Some scientists kindly pointed out some of the interesting features of my genetic landscape. And then they showed me how to navigate the data on my own. Ever since, I've been a genomic wayfarer. Whenever I come across some new insight into the links between our genes and our lives, I check my own DNA.

The Quest for Magma Energy

Nala Rogers, Inside Science

On a bright day in 1981, John Eichelberger stood on a blackened crust above billions of gallons of lava. Plumes of steam leaked from cracks in the basalt surface, driven upward by the lingering smolder of Hawaii's 1959 Kilauea eruption. That eruption had filled a crater hundreds of feet deep with liquid rock.
