Inflation Again: This Time with Feeling

Inflation is dead. Long live inflation.

Stellar Dust Disk Vanishes in 3 Years

According to widely accepted theory, planets evolve from orbiting dust disks surrounding stars. If so, planets trying to form in the dust around one young star didn't have much time. The disk evaporated within 3 years.

Animalympics

As summer Olympics season approaches, we should remember that we humans are not the only ones with some amazing physical abilities.

Scientific Markers Can Mislead

In historical sciences, observable phenomena are often used as indicators of past phenomena. Some recent examples show how these can mislead researchers.

Beethoven Rolls Under Darwin

Beethoven may indeed be rolling in his grave, but not for the reasons some Darwin-loving reporters think.

Too Hot to Handle: Io and Enceladus

Two moons in the solar system are turning up the heat on beliefs that they could be billions of years old.

Astronomers Wrestle with "Endless Mysteries"

Some of the biggest questions in the universe remain completely baffling to astronomers, a leading journal admitted.

Geology Can Be Explosively Rapid

When people hear of "geologic time," they are trained to think of millions of years. Big things can happen in far less time.

Doomed Worlds: Planets Seen Disrupting, Not Forming

Much as astrobiologists would like to see the birth of a new planet, the ones we observe seem to be dying, not being born.

Crater Count Dating Still Unreliable

Worries about the crater count dating method, widely relied upon to infer ages of planetary surfaces, began emerging in 2005. Those worries have not subsided; they have only grown worse. Crater numbers may have nothing to do with age.

Earth's Magnetic Field Less Sustainable than Thought

Geophysicists have found that their favored dynamo theory for Earth's magnetic field is less stable than thought, leaving them wondering how our planet sustained its magnetic field for "geologic time."

Dark Matter as an Escape

Employing exotic unobservable entities such as dark matter may be an escape from scientific rigor in more ways than one.

New Chirality Solution Proposed

It's long been a mystery why cells use one hand of two-handed molecules, like left-handed amino acids and right-handed sugars. A new proposal solves the mystery, explaining how this phenomenon called homochirality arises naturally. Wait a minute...

Planetary Radiometric Dates 1/3 Younger

The half-lives of radioactive isotopes may not be as well-known as thought. One decay rate frequently used to date solar system objects had to be adjusted down to 66% of its former assumed value, impacting theories of planet formation.

Animals Have Biological GPS

Global Positioning System (GPS): that's a function. Maintaining a suite of satellites is one method for achieving the function. But there are other ways to figure out where in the world you are, and two very different animals show the way – naturally – using Earth's global magnetic field.
