The Pandemic Everyone Fears

Dayna K. Myers, Global Health Now

If humanity is lucky, the next flu virus with pandemic potential will unfold somewhere quick to catch and contain the threata country with a strong public health service and well-stocked hospitals.If we're unlucky, a novel, lethal and highly infectious flu virus will break out in a crowded, unprepared megacity that lacks public health infrastructure.

Did Water-Based Life Originate Without Water?

Lisa Zyga, Phys.org

When trying to understand the origins of life on Earth, researchers run into a paradox: while water is an indispensable solvent for all known life forms that exist today, water also inhibits the formation of string-like chains of nucleic acid polymers such as RNA that were likely precursors of life. This raises the question: how could the nucleic acids have formed in the first place?

Lawyers Are Arguing That Coffee Causes Cancer

Alex B. Berezow, ACSH

A judge in California is going to determine whether or not coffee causes cancer.Think about that. We live in a society where judges and lawyers -- not medical doctors, scientists, or even a group of really clever AP biology high school students -- get to determine the credibility of biomedical research. The stakes are high: If coffee is deemed carcinogenic, then the State of California will be required to give up all pretense at common sense and sanity.

Why We Still Don't Have a Space Elevator

The Economist

FOR decades engineers and science-fiction writers have dreamed of lifts capable of carrying things into orbit from the Earth's surface. Konstantin Tsiolkovsky, a Russian scientist, suggested the idea in 1895, inspired by the Eiffel Tower. And in 1979 Arthur C. Clarke wrote an entire novel, The Fountains of Paradise, about the construction of such a space elevator.

Ancient Societies Deliberately Cultivated Weeds

Andrew Masterson, Cosmos

Plant domestication, the theory runs, comprises a long history during which humans select traits advantageous to farming practice. Qualities such as seed size, nutritional content, climatic resilience and reproductive reliability ideally become concentrated, resulting in a comparatively small number of widely cultivated plants.

How Responsible Are Killers with Brain Damage?

Micah Johnson, Sci American

Charles Whitman lived a fairly unremarkable life until August 1, 1966, when he murdered 16 people including his wife and mother. What transformed this 25-year-old Eagle Scout and Marine into one of modern America's first and deadliest school shooters? His autopsy suggests one troubling explanation: Charles Whitman had a brain tumor pressing on his amygdala, a region of the brain crucial for emotion and behavioral control.

Orca Taught to Imitate Human Words

Michelle Starr, Science Alert

A captive orca named Wikie has become the first killer whale known to recognisably make sounds that are not part of her native repertoire - including human language words like "hello" and "bye bye".An international team of researchers has just published a study demonstrating the talking abilities of 14-year-old Wikie, who lives at Marineland Aquarium in Antibes, France.

The Making of the Largest Satellite Constellation

Dan Oberhaus, Motherboard

Matt Desch didn't set out to change the world, but he just might do it anyway. As the CEO of Iridium, the only company that provides satellite communications to every inch of the globe, he is at the helm of Next, a fleet of telecommunications satellites that is arguably one of the most ambitious space projects ever undertaken.By this time next year, Iridium will have sent 75 Next satellites into orbit. Each one will be replacing a first-generation Iridium satellite that has been in orbit for almost two decades.

Robot Learns to Evolve Synthetic Protocells

James Urquhart, Chemistry World

An AI equipped robotic system that enables synthetic protocells to evolve could help unravel how complex life formed on Earth. The fully automated system, which make use of machine learning, could aid understanding of other complex chemical systems too.Oil-in-water droplets are often used as protocell models because, while chemically simple, they can exhibit complex and cell-like behaviours, such as movement and division.

Brain 'Pacemaker' Could Slow Alzheimer's

BBC News

LaVonne Moore has Alzheimer's disease, but her doctors hope her dementia symptoms could possibly be kept in check by a new type of treatment.Electric wires implanted deep in her brain stimulate areas involved with decision-making and problem-solving.

Old Fathers May Be Riskier Than Old Mothers

Robert D. Martin, NPR

This may be surprising to some: A woman's age is not alone in affecting pregnancy and birth, despite the impression often given.Reviewing Paul Raeburn's book Do Fathers Matter?, Tabitha Powledge wrote:

The Scientific Failure of the Original Elegant Universe

Ethan Siegel, Forbes

Scientific theories, at their best, are simple, straightforward, full of predictive power, and contain an elegance or beauty all their own. Newton's simple F = ma and Einstein's E = mc2 are simple equations that house profound truths and enable so much to be derived; the quark model and General Relativity are simple to describe but incredibly deep theories that govern the interactions of particles; ideas like supersymmetry, grand unification and string theory extend the known physical symmetries to even greater levels.

What Does It Mean to Die?

Rachel Aviv, The New Yorker

Before having her tonsils removed, Jahi McMath, a thirteen-year-old African-American girl from Oakland, California, asked her doctor, Frederick Rosen, about his credentials. How many times have you done this surgery? Hundreds of times, Rosen said. Did you get enough sleep last night? He'd slept fine, he responded.

Do Neutrons Decay into Dark Matter?

Clara Moskowitz, Scientific American

Neutrons shouldn't be all that mysterious. Found inside every atomic nucleus, they may seem downright mundanebut they have long confounded physicists who try to measure how long these particles can live outside of atoms. For more than 10 years researchers have tried two types of experiments that have yielded conflicting results.

A.I. Is the Weapon of the Next Cold War

Jeremy Straub, The Conversation

It is easy to confuse the current geopolitical situation with that of the 1980s. The United States and Russia each accuse the other of interfering in domestic affairs. Russia has annexed territory over U.S. objections, raising concerns about military conflict.

The 'Self' Is Real and Science Can Study It

Serife Tekin, Aeon Magazine

Know thyself' is one of philosophy's most ancient aphorisms. But is there such a thing as the self and, if there is, can it be empirically investigated through scientific methods? Antirealists deny the existence of the self for them it is an illusion, a fiction of the mind. If there was no one to perceive it, there would not be a self.

Wave of Volcanoes Created Earth's 1st Supercontinent

Alice Klein, NewScientist

The world's continents arrived in a blaze of fury. A pressure blow-out seems to have caused vast amounts of molten rock to spew out of the Earth and harden into solid land.Until about 2.2 billion years ago, Earth was mostly underwater. A few small landmasses existed, but nothing like the vast continents we have today.
