Biohybrid micro/nanorobots that integrate biological entities with artificial nanomaterials have shown great potential in the field of biotechnology. However, commonly used physical hybridization approaches can lead to blockages and damage to biological interfaces, impeding the optimal exploitation of natural abilities.

Viruses are tiny packets of destruction and there are more of them than any other biological entity on the planet.

Who doesn't like to be noticed by their company for going above and beyond the call at work, especially if there's bonus pay? Yet, subjective performance evaluations can lead to feelings of unfairness when they're not in an employee's favor.

How can we best employ human rights education when it comes to working with youth?

Meteors may help astronomers devise a new way to locate dark matter—mysterious and invisible particles that have so far only been discerned by the effect they have on the natural world.

In an apparent attempt to distract investors, firms forced to disclose bad news via mandatory Securities and Exchange Commission filings are more likely to issue a press release touting unrelated news around the time of the filing.

As municipal planning and design shifts away from the sprawling, car-centric model that dominated much of the 20th century, developers and local governments can disagree over how to grow cities sustainably. Transit-oriented development (TOD), which prioritizes population density, walkability, land-use diversity and parking around transit nodes, is a long-standing field. However, much of the research in past years has omitted the critical component of land development potential.

Deep below the ocean's surface, the seafloor contains large quantities of naturally occurring, ice-like deposits made up of water and concentrated methane gas. For decades, climate scientists have wondered if this methane hydrate reservoir might "melt" and release massive amounts of methane to the ocean and the atmosphere as ocean temperatures warm.

The types of ocean bacteria known to absorb carbon dioxide from the air require more energy—in the form of carbon—and other resources when they're simultaneously infected by viruses and face attack from nearby predators, new research has found.

Replete with tunneling particles, electron wells, charmed quarks and zombie cats, quantum mechanics takes everything Sir Isaac Newton taught about physics and throws it out the window.

Many of the drugs we utilize in modern medicine are naturally produced by microbes. Penicillin, an antibiotic derived from certain molds, is one of the most notable natural products due to its recognition as one of the biggest advances in medicine and human health. As DNA sequencing has become cheaper and faster, scientists now have access to hundreds of thousands of microbial genomes and the natural products they produce.

A new study from scientists at the University of Miami (UM) Rosenstiel School of Marine, Atmospheric, and Earth Science suggests that the pattern of temperature change of the world's oceans may not be an indication of an impending abrupt climate change event as depicted in the movie "The Day After Tomorrow."

Physicists at Ural Federal University (UrFU) and their colleagues from the Institute of Electrophysics, Ural Branch of the Russian Academy of Sciences, and the Institute of Ion Plasma and Laser Technologies, Academy of Sciences of Uzbekistan have developed a technology for the growth of nonspherical nanoparticles that are synthesized in the process of ion implantation.

Fresh water is a finite resource vulnerable to contamination.

A black-coated Canada lynx was photographed for the first time by a researcher at the University of Alberta, Canada. Thomas Jung, also employed by the Government of Yukon, recorded the animal in a 30 second video on a cell phone.

Hospital wastewater (HWW) contains plenty of persistent compounds, dangerous substances, and pathogenic microorganisms, such as antibiotics, psychiatric drugs, β-receptor blockers, anesthetics, analgesics, anti-inflammatory drugs, and X-ray contrast agents.

Bacteria produce slimy biofilms to coat and protect themselves and make them less susceptible to antimicrobial drugs and chemical cleaning products. The biofilms have implications for health and various industries, as they can cause fouling, corrosion and bacterial contamination.

Recently, a research team led by Prof. Qin Xiaoying from Hefei Institutes of Physical Science of Chinese Academy of Sciences found the thermoelectric properties of N-type Bi2Te2.7Se0.3(BTS) could be improved by introducing a small amount of Ag9AlSe6 nanoparticles into BTS matrix.

As more and more high-tech systems are exposed to the space environment, space weather prediction can provide better protection for these devices. In the solar system, space weather is mainly influenced by solar wind conditions. The solar wind is a stream of supersonic plasma-charged particles which will cause geomagnetic storms, affect short-wave communications, and threaten the safety of electricity and oil infrastructure when passing over the Earth.

Southwest Research Institute scientists have compiled 41 solar occultation observations of Saturn's rings from the Cassini mission. The compilation, published recently in the journal Icarus, will inform future investigations of the particle size distribution and composition of Saturn's rings, key elements to understanding their formation and evolution.

Jacks and barracuda in Heʻeia fishpond were found to feed on Australian mullet, an invasive species introduced to Oahu waters in the 1950s. This finding, published in Aquaculture, Fish, and Fisheries by researchers from the University of Hawaiʻi at Mānoa, University of California at Santa Barbara (UCSB), and Paepae O Heʻeia suggests that these native predatory fish may provide a form of biocontrol on populations of the invasive mullet species.

In the Late Viking Age, a grave was built that looks very similar to one of the most spectacular graves of the Roman Age in Norway.

Satellites face greater chances of collision with space debris as a result of reduced density in the upper atmosphere.

River herring once swam up Connecticut's streams to reproduce by the billion, and then reverse their journey back to sea. In recent years, though, their migration has become increasingly perilous, and their numbers have plummeted. Obstructions like dams have been added to many of the streams and rivers and the population has been drastically overfished.

A new model gives wildlife managers the ability to gather the necessary data in a matter of minutes
