NASA astronauts aboard the International Space Station will conduct a spacewalk on Wednesday, Dec. 21, to install a rollout solar array to increase electrical power in support of operations and scientific research.
Read MoreUsing an egg ‘soup’ to understand how DNA is packed in the nucleus
If you stretched the DNA found in one of your cells from end to end, it would extend approximately 2 meters or 6.5 feet. Every single cell in your body can pack away this much DNA by winding it around proteins called histones. The DNA is opened and closed when cells need access for normal […]
Read MoreHow the science behind epidemics helped physicists develop state-of-the-art conductive paint
In new research published in Nature Communications, University of Sussex scientists demonstrate how a highly conductive paint coating that they have developed mimics the network spread of a virus through a process called ‘explosive percolation’—a mathematical process which can also be applied to population growth, financial systems and computer networks, but which has not been […]
Read MoreA new method to recycle Nylon-6 by unlinking polymer chains
Nylon-6 is a tough, non-biodegradable plastic that cannot be recycled by conventional methods. A new way has now been introduced by a team from the U.S. in the journal Angewandte Chemie International Edition.
Read MoreTrouble at ACS – And at C&E News
Many chemists will have heard about some recent upheavals at the American Chemical Society, and specifically with the society’s relationship to its magazine, Chemical and Engineering News. That’s been a constant part of most our lives as chemists, ACS members or not, and to be honest there have always been some friction points in how […]

Mysterious ichthyosaur graveyard may have been a breeding ground
Some 230 million years ago, massive dolphinlike reptiles called ichthyosaurs gathered to breed in safe waters — just like many modern whales do. That’s the conclusion that researchers arrived at after studying a mysterious ichthyosaur graveyard in Berlin-Ichthyosaur State Park in Nevada. The park is home to the world’s richest assemblage of fossils of […]

Long genital spines on male wasps can save their lives
Fending off an attacker by swordplay with two genital spines turns out to be a moderately useful form of self-defense for male wasps, an unusual study shows. A mason wasp’s rear spikes may be useless when it comes to delivering sperm, but they could save his life. Male wasps (and bees) don’t grow venom-injecting stingers. […]
Read MoreMeasuring gamma-ray bursts’ hidden energy unearths clues to the evolution of the universe
When stars die out, they emit gamma-ray bursts. Although scientist can calculate the explosion energy from dying stars, it is difficult to do when the conversion efficiency is low or unknown. Using light polarization, a research group has found a workaround for this, enabling astronomers to calculate the hidden energy of gamma-ray bursts.

Researchers have developed a method that allows a flapping-wing robot to land autonomously on a horizontal perch using a claw-like mechanism. The innovation could significantly expand the scope of robot-assisted tasks.
