Rochester Institute of Technology and the Instituto Argentino de Radioastronomía (IAR) have collaborated to make the first pulsar observations from South America.

Officials from almost 200 countries hunkered down for another night of talks late Friday as a U.N. climate meeting in Madrid went into overtime without agreement on key issues.

Growing up in the wild makes plants tough. Wild plants evolve to survive the whims of nature and thrive in difficult conditions, including extreme climate conditions, poor soils, and pests and disease. Their better-known descendants—the domesticated plants that are critical to a healthy diet—are often not nearly as hardy. The genes that make crop wild relatives robust have the potential to...

Born pink, blind, and helpless, giant pandas typically weigh about 100 grams at birth—the equivalent of a stick of butter. Their mothers are 900 times more massive than that.

Scientists at Tokyo Institute of Technology (Tokyo Tech) have developed a new methodology that allows researchers to assess the chemical composition and structure of metallic particles with a diameter of only 0.5 to 2 nm. This breakthrough in analytical techniques will enable the development and application of minuscule materials in the fields of electronics, biomedicine, chemistry, and more.

In the world of squirrels, moving away from your home turf has better outcomes for males than for females, according to a new study by University of Alberta ecologists.

With the popularity of online shopping, it's no secret brick-and-mortar stores are fighting to stay relevant. Waiting area entertainment is one way they are standing out, because no one likes to wait. New research in the INFORMS journal Manufacturing & Service Operations Management says funding entertainment is no easy task, but one way to offset the price and increase customer experience and...

A new approach to trapping light in artificial photonic materials by a City College of New York-led team could lead to a tremendous boost in the transfer speed of data online.

Buzzing chainsaws are interrupted by the frequent crash of breaking branches as crews fell towering trees and clear tangled brush in the densely forested Santa Cruz Mountains south of San Francisco.

Antiparticles—subatomic particles that have exactly opposite properties to those that make up everyday matter—may seem like a concept out of science fiction, but they are real, and the study of matter-antimatter interactions has important medical and technological applications. Marcos Barp and Felipe Arretche from the Universidade Federal de Santa Catarina, Brazil have modelled the interaction...

A type of Martian aurora first identified by NASA's MAVEN spacecraft in 2016 is actually the most common form of aurora occurring on the Red Planet, according to new results from the mission. The aurora is known as a proton aurora and can help scientists track water loss from Mars' atmosphere.

Made up of 2-D sheets of carbon atoms arranged in honeycomb lattices, graphene has been intensively studied in recent years. As well as the material's diverse structural properties, physicists have paid particular attention to the intriguing dynamics of the charge carriers its many variants can contain. The mathematical techniques used to study these physical processes have proved useful so far,...

Researchers at Duke University have engineered a bandage that captures and holds a pro-healing molecule at the site of a bone break to accelerate and improve the natural healing process.

In 2015, the first commercial nanopore DNA sequencing device was introduced by Oxford Nanopore Technologies. Based on a synthetically engineered transmembrane protein, nanopore sequencing allows long DNA strands to be channelled through the central lumen of the pore where changes in the ionic current work as a sensor of the individual bases in the DNA. This technique was a key milestone for DNA...

The manipulation of rivers in California is jeopardizing the resilience of native Chinook salmon. It compresses their migration timing to the point that they crowd their habitats. They may miss the best window for entering the ocean and growing into adults, new research shows.

How is knowledge exchanged and shared when interdisciplinary research teams work together? Professor Margarete Boos and Lianghao Dai from the University of Göttingen have investigated this by studying several different research projects. Their study makes concrete recommendations for how teams can best work together and achieve effective collaborations. The results have been published in the...

Control of the polarization of light is a key feature for displays, optical data storage, optical quantum information, and chirality sensing. In particular, the direct emission of circularly polarized (CP) light has attracted great interest because of the enhanced performance of displays such as organic light-emitting diodes (OLEDs) and light sources for characterizing the secondary structure of...

TSCs are emerging devices that combine the advantages of visible transparency and light-to-electricity conversion. One of the valuable prospective applications of such devices is their integration into buildings, vehicles, or portable electronics. Therefore, colour-perception and flexibility are important as well as efficiency. Currently, existing transparent solar cells are based predominantly on...

A team of researchers at McMaster University has developed a self-cleaning surface that can repel all forms of bacteria, preventing the transfer of antibiotic-resistant superbugs and other dangerous bacteria in settings ranging from hospitals to kitchens.

From Sudan to Syria to Bangladesh, climate change is often presented as a powerful and simple root cause of violent conflict and mass migration.
