Exploring the transferability of extracytoplasmic function switches across bacterial species
Extracytoplasmic function sigma factors (ECFs) have been successfully used for constructing predictable artificial gene circuits in bacteria like Escherichia coli, but their transferability between species within the same phylum remained unknown......»»
Study details a common bacterial defense against viral infection
One of the many secrets to bacteria's success is their ability to defend themselves from viruses, called phages, that infect bacteria and use their cellular machinery to make copies of themselves......»»
Genomic analysis of a species of zooplankton questions assumptions about speciation and gene regulation
When two animals look the same, eat the same, behave the same way, and live in similar environments, one might expect that they belong to the same species......»»
New structures offer insight into how a bacterial motor powers bacterial chemotaxis, a key infectious process
Bacteria existed for millennia before humans and have been infecting us from the beginning. Although we can treat infections through pharmaceuticals, bacteria continue to become resistant to treatment thanks to their rapid evolution. Bacterial infect.....»»
Gigantic Jurassic raptor footprints unearthed in China
Scientists have discovered the tracks of a 5 meter-long raptor dinosaur, challenging what was previously known about the species' size range......»»
Yeast study offers possible answer to why some species are generalists and others specialists
In a landmark study based on one of the most comprehensive genomic datasets ever assembled, a team led by scientists at the University of Wisconsin–Madison and Vanderbilt University offer a possible answer to one of the oldest questions about evolu.....»»
First chromosome-level reference genomes of the ornamental banana and pink banana
The genus Musa, encompassing approximately 70 herbaceous species, is predominantly found in the tropical and subtropical regions of Asia and Oceania. This genus is renowned for being one of the most important food crops globally and popular ornamenta.....»»
Uncovering the diversity of Micropsalliota: Seven new species and one newly recorded species in southern China
Species of Micropsalliota (Basidiomycota, Agaricomycetes, Agaricales, Agaricaceae) are mainly distributed in tropical and /or subtropical regions. These fungi are saprophytic in general and can decompose lignin and cellulose, and thus have significan.....»»
Scientists map soil RNA to fungal genomes to understand forest ecosystems
If a tree falls in the forest—whether or not anyone registers the sound—one thing is for sure: there are lots of fungi around. Within a forest's soil, hundreds of species decompose debris, mobilize nutrients from that decay, and deliver those nut.....»»
The high and mighty Himalayas: A biodiversity hotbed facing significant challenges
The Himalayas are home to a vast diversity of species, consisting of 10,000 vascular plants, 979 birds and 300 mammals, including the snow leopard, the red panda, the Himalayan tahr and the Himalayan monal......»»
Most bees don"t die after stinging—and other surprising bee facts
Most of us have been stung by a bee and we know it's not much fun. But maybe we also felt a tinge of regret, or vindication, knowing the offending bee will die. Right? Well, for 99.96% of bee species, that's not actually the case......»»
These giant, prehistoric salmon had tusk-like teeth
Oncorhynchus rastrosus, a giant species of salmon that lived in the North American Pacific Northwest a few million years ago, sported a pair of front teeth that projected out from the sides of its mouth like tusks, according to a study published Apri.....»»
Unveiling the mysteries of cell division in embryos with timelapse photography
The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis are well-studied in the so-called somatic cells—the cells that have a specialized function, like skin and muscle cells—they remain elusive in the first cells of.....»»
A key gene helps explain how the ability to glide has emerged over-and-over during marsupial evolution
People say "When pigs fly" to describe the impossible. But even if most mammals are landlubbers, the ability to glide or fly has evolved again and again during mammalian evolution, in species ranging from bats to flying squirrels. How did that come a.....»»
Illinois residents encouraged to destroy the eggs of invasive insects to slow spread
While Chicagoans were alarmed to learn the spotted lanternfly had been found in Illinois last year, experts say spring is the time to take action against that insect—as well as another damaging invasive species that has made far more inroads and go.....»»
Study finds climate change is helping tropical fish invade Australian ocean water
A University of Adelaide study of shallow-water fish communities on rocky reefs in south-eastern Australia has found climate change is helping tropical fish species invade temperate Australian waters. The work is published in the Journal of Animal Ec.....»»
Researchers uncover natural variation in wild emmer wheat for broad-spectrum disease resistance
Bread wheat is one of the most important staple crops for millions of people and is apparently the largest cultivated and traded cereal worldwide. Bread wheat is a hexaploid species with three subgenomes (2n = 6x = 42, AABBDD) that has undergone two.....»»
Researchers report on mechanisms of gene regulatory divergence between species
Closely related animal species can look physically different, but you might be surprised to learn that those differences can result not only from DNA sequence changes that alter proteins' structure or function, but also because changes in the DNA aff.....»»
Yes, the YouTube app now hijacks your Apple TV’s screen saver
One of the best features of the Apple TV is its robust collection of Aerial screen savers. When your Apple TV sits idle for a few minutes, tvOS switches to these soothing Aerial videos while it awaits your return. YouTube, however, thinks you’d.....»»
