Select Memories Can Be Erased, Leaving Others Intact

Different types of memories stored in the same neuron of the marine snail Aplysia can be selectively erased, according to a new study by researchers at Columbia University Medical Center (CUMC) and McGill University and published today in Current Biology.

Hubble Captures Massive Dead Disk Galaxy That Challenges Theories of Galaxy Evolution

STSCI-H-p1726a-d-1280x720.png

Astronomers combined the power of a “natural lens” in space with the capability of the Hubble Space Telescope to make a surprising discovery—the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang. Researchers say that finding such a galaxy so early in the history of the universe challenges the current understanding of how massive galaxies form and evolve.

Wet and Stormy Weather Lashed California Coast…8,200 Years Ago

SC_FigS2-hires.jpg

An analysis of stalagmite records from White Moon Cave in the Santa Cruz Mountains shows that 8200 years ago the California coast underwent 150 years of exceptionally wet and stormy weather. It is the first high resolution record of how the Holocene cold snap affected the California climate.

Chaotically Magnetized Cloud Is No Place to Build a Star, or Is It?

To make a star, the conditions inside interstellar gas clouds have to be "just right." When it comes to a cloud's magnetic fields, however, those conditions may range from powerful and orderly to weak and chaotic, according to new ALMA observations.

Wildfires Pollute Much More Than Previously Thought

Wildfires are major polluters. Their plumes are three times as dense with aerosol-forming fine particles as previously believed. For the first time, researchers have flown an orchestra of modern instruments through brutishly turbulent wildfire plumes to measure emissions in real time. They have also exposed other never before measured toxins.

Researchers Pinpoint How Detecting Social Signals May Have Affected How We See Colors

Higham2017Web.jpg

The arrangement of the photoreceptors in our eyes allows us to detect socially significant color variation better than other types of color vision, a team of researchers has found. Specifically, our color vision is superior at spotting “social signaling,” such as blushing or other facial color changes—even when compared to the type of color vision that we design for digital cameras and other photographic devices.

Study: Collateral Damage from Cosmic Rays Increases Cancer Risks for Mars Astronauts

Cucinotta_Newswise.jpg

The cancer risk for a human mission to Mars has effectively doubled following a UNLV study predicting a dramatic increase in the disease for astronauts traveling to the red planet or on long-term missions outside the protection of Earth's magnetic field. New predictive model, published in Scientific Reports, shows radiation from cosmic rays extends from damaged to otherwise healthy 'bystander' cells.

Hubble's Tale of Two Exoplanets: Nature vs. Nurture

STSCI-H-p1722a-d890x720.png

Scientists using NASA's Hubble Space Telescope to study two "hot Jupiter" exoplanets--having virtually the same size and temperature, and orbiting around nearly identical stars at the same distance--hypothesized that the planets' atmospheres should be alike. But the researchers found that one planet's atmosphere was much cloudier than the other.
