New paper highlights the co-benefits of coordinating climate action and peacebuilding

Climate change can manifest in different ways: stronger tropical droughts, extreme droughts, warmer climates and highly unpredictable rainfall patterns. All these endanger the availability of food, which in turn could increase conflict over resources, which can turn violent in the absence of spaces for dialogs and negotiations to transform conflict by peaceful means. Violent conflict affects...

Genomes OnLine Database introduces new features

Since its launch 25 years ago, the Genomes OnLine Database (GOLD) has matured from six projects on a spreadsheet into a flagship genomic metadata repository, making curated microbiome metadata that follows community standards freely available, and enabling large-scale comparative genomics analysis initiatives.

Researchers unveil evolution of paleodiet at Neolithic Qujialing site

The sustainable development of agriculture has laid a solid foundation for the birth of human civilization and countries. Early agriculture has long been a focus of archaeology. China is the only country in the world with two independent agricultural systems, that is, rice farming in the south and millet farming in the north.

Astronomers see stellar self-control in action

Many factors can limit the size of a group, including external ones that members have no control over. Astronomers have found that groups of stars in certain environments, however, can regulate themselves.

Searching for new particles using quantum sensors

In a recent study published in the journal National Science Review, a laboratory search for exotic spin-dependent interactions was conducted with an ensemble-NV-diamond magnetometer. New experimental constraints on two types of exotic interactions were established at the micron scale.

Oldest Pterodactylus fossil found in Germany

Pterosaurs, the flying reptiles of the dinosaur era, originated in the Late Triassic (227 million years ago) and became extinct at the end-Cretaceous extinction event (66 million years ago). With wing spans ranging from 1 to 12 meters, they dominated the world's skies for more than 160 million years.

Team creates nano-magnets that could restore damaged nerve cells

Neurons are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at every step in between. Neurons, also called nerve cells, are composed of three main parts: the cell body, the dendrites and the axon—a long, thin...

Flexible strain sensor enabled by carbon nanofibers can 'read lips'

Wearable, flexible strain sensors unobtrusively monitor tiny vibrations of human skin in real time and with great accuracy, thanks to innovative fabrication techniques using composite materials. High sensitivity and a wide working range are key parameters for a high-quality strain sensor, but it's difficult to attain both characteristics on the same sensor due to limitations in structure and...

Scientists propose framework for understanding establishment of plants after long-distance dispersal

Mechanisms of plant colonization after long-distance dispersal (LDD) and current related knowledge were the topic of a review by Prof. Li Dezhu's team at the Kunming Institute of Botany of the Chinese Academy of Sciences (CAS), in collaboration with researchers from the Xishuangbanna Tropical Botanical Garden of CAS, the Hebrew University of Jerusalem, and the University of Edinburgh.

Increasing crop yields by breeding plants to cooperate

A simple breeding experiment, combined with genetic analysis, can rapidly uncover genes that promote cooperation and higher yields of plant populations, according to a new study published November 29 in the open access journal PLOS Biology, by Samuel Wuest of the University of Zurich and Agroscope, Switzerland, and colleagues. The results have the potential to quickly increase crop productivity...

Bats are the death metal singers of the animal world, research shows

Mammals can produce sound from ventricular folds, used by humans only for Tuvan throat singing and ‘death metal grunting’It has long been known Ozzy Osbourne has a taste for bats. But now it seems the mammals are also fans of his.Bats greet each other with death metal growls, scientists have discovered, and possess a vocal range which far surpasses that of most humans. Continue...
