The latest science news from Science Daily

An innovative, eel-like robot developed by engineers and marine biologists can swim silently in salt water without an electric motor. Instead, the robot uses artificial muscles filled with water to propel itself. The foot-long robot, which is connected to an electronics board that remains on the surface, is also virtually transparent.

New research shows that a surprising amount of water survives simulated asteroid impacts, a finding that may help explain how asteroids deposit water throughout the solar system.

Using high-powered laser beams, researchers have simulated conditions inside a planet three times as large as Earth. The pressures achieved in this study, up to 1,314 gigapascals (GPa), allowed researchers to gather the highest-pressure X-ray diffraction data ever recorded and generate new, more robust models for the interior structure of large, rocky exoplanets.

A massive decade-long study of Western Equatorial Africa's gorillas and chimpanzees has uncovered both good news and bad about our nearest relatives. The good news: there are one third more western lowland gorillas and one tenth more central chimpanzees than previously thought. The bad news: the vast majority of these great apes (80 percent) exist outside of protected areas, and gorilla populations are declining by 2.7 percent annually.

In a groundbreaking new study, researchers used a customized, low-cost 3-D printer to print electronics on a real hand for the first time. The technology could be used by soldiers on the battlefield to print temporary sensors on their bodies to detect chemical or biological agents or solar cells to charge essential electronics.

The elusive quantum mechanical phenomenon of entanglement has now been made a reality in objects almost macroscopic in size. Results show how two vibrating drumheads, the width of a human hair, can display the spooky action that famously troubled Albert Einstein.

For the first time, astronomers have witnessed the birth of a colossal cluster of galaxies. Their observations reveal at least 14 galaxies packed into an area only four times the diameter of the Milky Way's galactic disk. Computer simulations of the galaxies predict that over time the cluster will assemble into one of the most massive structures in the modern universe.

Telomerase, because of its role in cancer and aging, has long been a target of drug companies who want to block it to stop the uncontrolled cell growth characteristic of cancer, or boost it to create a fountain of youth. The structure of the enzyme complex has been a mystery, however, until now. Scientists have finally obtained a detailed picture of the architecture of the RNA-protein complex, a breakthrough for drug design.

Researchers proposes a new evolutionary origin for mitochondria -- also known as the 'powerhouses of the cell.' Mitochondria are energy-converting organelles that have played key roles in the emergence of complex cellular life on Earth.

Researchers have helped design a compact switch that enables light to be more reliably confined to small computer chip components for faster information processing.
