Phys.org / Bees and fish exposed to crop chemicals show significant behavioral changes
Plant protection products protect crops from pests, diseases and weeds. However, many of the fungicides, herbicides and insecticides also have a negative effect on terrestrial and aquatic organisms such as pollinators or ...
Phys.org / A genetic switch lets plants accept nitrogen-fixing bacteria
Researchers are one step closer to understanding how some plants survive without nitrogen. Their work could eventually reduce the need for artificial fertilizer in crops such as wheat, maize, or rice.
Phys.org / NASA's ESCAPADE mission to Mars—twin satellites dubbed Blue and Gold will launch in early November
The first dual-satellite mission to another planet, NASA's ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers), is scheduled for launch no earlier than Sunday, Nov. 9, from Cape Canaveral, Florida. The two identical ...
Phys.org / Entanglement swapping using sum-frequency generation between single photons demonstrated for first time
The National Institute of Information and Communications Technology (NICT) has successfully demonstrated entanglement swapping (one of the key quantum communication protocols) using sum-frequency generation (SFG) between ...
Phys.org / Woodpeckers grunt and brace their bodies like athletes to maximize drilling power
Woodpeckers pack a punch, pounding wood with extreme force and experiencing decelerations of up to 400g. Now, researchers reveal in the Journal of Experimental Biology that drilling woodpeckers turn themselves into hammers ...
Phys.org / Three newly discovered toads give birth to live young
An international team of researchers has discovered three new, bizarre, and wart-covered species of tree toads from Tanzania that give birth to fully developed toadlets. A key element of the study was the examination of specimens ...
Phys.org / Quantum 'pinball' state of matter in electrons allows both conducting and insulating properties, physicists discover
Electricity powers our lives, including our cars, phones, computers, and more, through the movement of electrons within a circuit. While we can't see these electrons, electric currents moving through a conductor flow like ...
Phys.org / Compact laser system shows 80% efficiency for ultrashort light pulses is possible
Lasers that emit extremely short light pulses are highly precise and are used in manufacturing, medical applications, and research. The problem: efficient short-pulse lasers require a lot of space and are expensive.
Phys.org / Kinase atlas uncovers hidden layers of cell signaling regulation
The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme's "tail" called phosphorylation patterns.
Phys.org / Mapping a new frontier with AI-integrated geographic information systems
Over the past 50 years, geographers have embraced each new technological shift in geographic information systems (GIS)—the technology that turns location data into maps and insights about how places and people interact—first ...
Phys.org / Growing transgenic plants in weeks instead of months by hijacking a plant's natural regeneration abilities
Plant biologists have developed a method for growing transgenic and gene-edited plants that cuts the slow and expensive process down from months to weeks.
Phys.org / Experimental evolution uncovers how bacteria develop drug resistance
The bacteria Acinetobacter baumannii (A. baumannii) is a haunting presence in many hospitals in the United States, where more than one in 100 patients are treated for A. baumannii infections. This species of bacteria is known ...
