Bizarre Particles Flying Out of Antarctica's Ice

Rafi Letzter, Space.com

There's something mysterious coming up from the frozen ground in Antarctica, and it could break physics as we know it.Physicists don't know what it is exactly. But they do know it's some sort of cosmic ray a high-energy particle that's blasted its way through space, into the Earth, and back out again. But the particles physicists know about the collection of particles that make up what scientists call the Standard Model (SM) of particle physics shouldn't be able to do that.

The Organic Food Industry Gets Fat on Lies

Henry Miller, RealClearScience

In The Wealth of Nations, the 18th century economist and philosopher Adam Smith observed about the chicanery of some businessmen, People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices. Nowhere is that truer than in today's organic agriculture and food industries.

Rat Version of Hepatitis E Found in Humans for First Time

George Dvorsky, Giz

A 56-year-old man from Hong Kong has contracted the rat-specific version of hepatitis E, something never observed before in a human patient. Health officials are now scrambling to understand how this could have happenedand the possible implications.

Antibiotics May Treat Appendicitis Without Surgery

Brigit Katz, Smithsonian

When a patient presents at the hospital with appendicitis, the standard course of action is to remove the appendix in an emergency surgery. But as the Associated Press reports, a new study published in the Journal of the American Medical Association suggests that there may be an effective, but less invasive alternative to treating appendicitis: antibiotics.

Uncommon "Medicane" Storm Headed for Greece

Dennis Mersereau, Pop Sci

An uncommon type of storm known as a Medicane is swirling to life in the eastern Mediterranean Sea. The nicknamea portmanteau of Mediterranean and hurricaneis given to low-pressure systems that form over the sea and take on tropical or subtropical characteristics. Storms of this nature only form once or twice a year due to the Mediterranean sea's cool waters.

Trinkets Under Churches Reveal Middle Ages Religion

Ingrid P. Nuse, SciNordic

Archaeologists have unearthed vast quantities of coins, pearls, and hairpins under the floors of medieval churches throughout Scandinavia.More than 20,000 coins have been found in Norway alone, half of which date to between 1180 CE and 1320 CE.

Cosmic Dust Could Reveal New Types of Galaxies

Gareth Willmer, Horizon

Measuring the vast quantities of cosmic dust in interstellar space may be a key to unlocking various mysteries of the cosmos, including how the grains form and whether new types of galaxy are obscured by the particle clouds.Cosmic dust grains, which are born in stars, are the building blocks for other stars and rocky planets such as Earth as well as maybe life itself. However, our understanding of the dusty universe and the processes that form it remains limited.

'Traffic Jams' of Cells Help to Sculpt Embryos

Jordana Cepelewicz, Quanta

What do incipient organs, traffic jams and the frothy head of foam at the top of a beer glass have in common? Far more than expected, according to results published in Nature earlier this month. For the first time, using a series of clever, state-of-the-art techniques, scientists have uncovered the balance of physical forces that shapes tissues in developing embryos.

Can the Ghost Dolphin Survive Obscurity?

Forest Ray, Hakai Magazine

A ghost haunts the coasts of southern Brazil, Uruguay, and northern Argentina. The franciscana, cousin to the Amazon River dolphin, is also known as the La Plata dolphin, for the river in which it was first sighted, and as the ghost dolphin, for its rarity. The franciscana is officially listed as vulnerable, although so little is known about the elusive mammal it may effectively be endangered.

The Tragic Story of Hans Hellmann

Andrew Grant, Physics Today

In 1933, quantum chemist Hans Hellmann was one of the hundreds of German professors who lost their posts when all non-Aryans were deemed unfit for civil service. A year later, he fled Nazi Germany with his family to seek refuge and employment in the USSR, where he received a prestigious appointment from the state and became a Soviet citizen.

The Pieces of Mars That Have Landed on Earth

Ethan Siegel, Forbes

As the planets orbit the Sun, well-separated from one another, we tend to assume they don't exchange material very frequently. The Solar System may be a violent place, rife with asteroid strikes and cometary collisions, but planets themselves are too big and massive to be affected by these. When large, energetic collisions impact your planet, the worst they typically do is create a crater and blanket your world in debris.

How to Search for Dead Cosmic Civilizations

Abraham Loeb, Scientific American

The rate of growth of new technologies is often proportional to past knowledge, leading to an exponential advance over time. This explosive process implies that very quickly after a civilization reaches technological maturity, it will develop the means for its own destruction through climate change, for example, or nuclear, biological or chemical weapons.

Atheists Are Not as Rational as They Think

Lois Lee, Conversation

Many atheists think that their atheism is the product of rational thinking. They use arguments such as I don't believe in God, I believe in science to explain that evidence and logic, rather than supernatural belief and dogma, underpin their thinking.

Beware of Epistocracy

Steven Novella, Neurologica

OK this is my new favorite word: epistocracy. I first encountered it reading an article about attempts by the Indian government to control what passes for knowledge. It has the same root as epistomology which is the philosophy of knowledge, or how to legitimately separate opinion from fact.

Why Atheists Are Not as Rational as They Like to Think

Lois Lee, Conversation

Many atheists think that their atheism is the product of rational thinking. They use arguments such as I don't believe in God, I believe in science to explain that evidence and logic, rather than supernatural belief and dogma, underpin their thinking.

Templeton Funds More Atheist Bashing

Jerry Coyne, Why Evolution Is True

Lois Lee, a religious scholar whom I've written about before, is the lead investigator on a big Templeton grant, or, as The Conversation describes her in erroneous spelling, Principle [sic] Investigator on the Understanding Unbelief programme. Templeton gave her and her co-PI Stephen Bullivant (also a religious scholar) nearly three million dollars to study the nature and variety of unbelief.

Life as an Accelerator Operator

Shannon Brescher Shea, Symmetry

One Friday night in March, accelerator operator Alyssa Miller was chatting with fellow staff members in the rec center at the US Department of Energy's Fermi National Accelerator Laboratory right after she finished her shift. As they talked, several of her colleagues' cell phones started buzzing. Scrambling to check their messages, they realized the local utility company had abruptly stopped providing the accelerator complex with electricity.

Can We Understand the Fine Structure Constant?

Sean Carroll, Prep Universe

Sir Michael Atiyah, one of the world's greatest living mathematicians, has proposed a derivation of , the fine-structure constant of quantum electrodynamics. A preprint is here. The math here is not my forte, but from the theoretical-physics point of view, this seems misguided to me.

What Can Sci-Fi Teach Us About the Space Force?

Matt Kamen, Wired UK

Donald Trump's Space Force, whatever it ends up becoming, brushes right up against the limits of science fiction, where images of interplanetary fleets are common. With a proposed budget of $8 billion over five years relatively paltry, given the costs involved with space exploration, especially at military scale it's more likely that whatever materialises in the real world will be more of a domestic defence shield than a star convoy.

How (Not) to Win a Nobel Prize in Physics

Yuen Yiu, Inside Science

On Oct. 2, we will find out who will win this year's Nobel Prize in physics. If you've published your own earth-shattering discovery about the physical world, you might be wondering if you can expect an early morning call. An analysis of past winners reveals some trends.

Lasers Reveal Ancient Mayans' Surprising Complexity

Bruce Bower, ScienceNews

A laser-shooting eye in the sky has revealed the previously unappreciated size and complexity of ancient Maya civilization, both before and during its presumed heyday, scientists say.Maya people in what's now northern Guatemala built surprisingly extensive defensive structures and roads as part of political systems featuring interconnected cities, starting at least several hundred years before the rise of Classic Maya society, an international team reports in the Sept. 28 Science. Classic Maya sites date to between around 250 and 900.

The Fourth Copernican Revolution

Martin Rees, Nautilus

The sun formed 4.5 billion years ago, but it's got around 6 billion years more before its fuel runs out. It will then flare up, engulfing the inner planets. And the expanding universe will continueperhaps foreverdestined to become ever colder, ever emptier. To quote Woody Allen, eternity is very long, especially toward the end.

Blobs Beneath Earth Could Be Remnants of Magma Ocean

Stephanie Pappas, LS

Mysterious blobs deep in the Earth's mantle could be minerals that precipitated out of an ancient magma ocean that formed in the collision that also created the moon.These blobs, called ultralow velocity zones, are found very deep in the mantle, close to the Earth's core. They are known only because when seismic waves from earthquakes travel through them, the waves slow dramatically.

In New York, Rats Are Beating Cats

Tanya Loos, Cosmos Magazine

Feral cats fail to fulfil their role as rat controllers in New York City, new research reveals.Cats (Felis catus) are often released in New York in the belief that they will make a dent on the city's centuries-old rat problem. However, a study of the two species in the mean streets of Gotham reviewed 306 videos of cat-rat interactions over a 79-day period and found that just two yes, two rodents lost their lives.

How Reliable Are the Memories of Sexual Assault Victims?

Jim Hopper, Sci Am

Incomplete memories of sexual assault, including those with huge gaps, are understandableif we learn the basics of how memory works and we genuinely listen to survivors. Such memories should be expected. They are similar to the memories of soldiers and police officers for things they've experienced in the line of fire.

60 Years of DARPA's Favorite Inventions

Evan Ackerman, IEEE Spectrum

This year, the U.S. Defense Advanced Research Projects Agency (DARPA) turned 60. To celebrate, DARPA held a conference in Washington, D.C. One of the highlights was an exhibit hall full of both current DARPA programs as well as unique artifacts from DARPA's history. We've put together a gallery of the most interesting things we saw there.

A Drug Intoxication Mimics Brain Death

Ross Pomeroy, RealClearScience

In a new case report, Turkish doctors from Dokuz Eylul University present a curious case of drug intoxication mimicking brain death. Their account is published in Acta Neurologica Belgica.At an unstated date, a 15-year-old female was discovered unresponsive surrounded by various empty bottles of pharmaceuticals, including aspirin, acetominaphen, and the migraine drug diclofenac sodium.

Is the Ketamine Boom Getting out of Hand?

Megan Thielking, Stat

Walk into Kalypso Wellness Centers in San Antonio, Texas, and you might be treated with one of five proprietary blends of ketamine. They're not cheap $495 per infusion and not covered by insurance, but the company offers a monthly membership program to cut costs and advertises discounts for members of the military and first responders.

Australia's Gun Control Laws Likely Won't Work in U.S.

Karen Kaplan, L.A. Times

On a spring day in the Tasmanian town of Port Arthur, a lone gunman shot an elderly couple at the inn they owned, 22 diners lunching at a nearby tourist spot, two tour bus drivers and several of their passengers, four occupants of a BMW, and two customers at a gas station.

Genetic Determinism Rides Again

Nathaniel Comfort, Nature News

It's never a good time for another bout of genetic determinism, but it's hard to imagine a worse one than this. Social inequality gapes, exacerbated by climate change, driving hostility towards immigrants and flares of militant racism. At such a juncture, yet another expression of the discredited, simplistic idea that genes alone control human nature seems particularly insidious.
