These freeze-drying algae can awaken from cryostasis, and could help spaceflights go farther
Antarctica's McMurdo Dry Valleys contain some of Earth's coldest and driest deserts. The environment there is so extreme that the Dry Valleys have been used as Mars analogs to test prototype equipment for future Mars exploration......»»
Cold storage research could put a freeze on red meat waste
A new report shows inconsistent fridge temperatures and confusing cold storage advice could be contributing to meat waste in Aussie households......»»
Soft, living materials made with algae glow under stress
A team of researchers led by the University of California San Diego has developed soft yet durable materials that glow in response to mechanical stress, such as compression, stretching or twisting. The materials derive their luminescence from single-.....»»
Mimicking a bird"s sticky spit to create cellulose gels
Using a small bird's nest-making process as a model, researchers from North Carolina State University have developed a nontoxic process for making cellulose gels. The freeze-thaw process is simple, cost-effective, and can create cellulose gels that a.....»»
Thousands of programmable DNA-cutters found in algae, snails, and other organisms
A diverse set of species, from snails to algae to amoebas, make programmable DNA-cutting enzymes called Fanzors—and a new study from scientists at MIT's McGovern Institute for Brain Research has identified thousands of them. Fanzors are RNA-guided.....»»
Scientists explain unique formation of ancient algae that evolved photosynthesis and oxygenated the planet
Scientists have for the first time revealed how blue-green algae—visible as the slippery green slime in stagnant water, riverbeds, and seashores—weaves itself into large weblike structures......»»
New map shows how climate change affects your community and its vulnerability to weather
Across the globe, the past few years have been characterized by scorching summers that endanger the health of outdoor workers and biting winters that often freeze pipes and other critical infrastructure......»»
Scientists build a spatial atlas of the chloroplast proteome, the home of photosynthesis
Plants and algae convert solar energy into chemical energy through photosynthesis. This process is vital for life on Earth and provides us with oxygen, food, fuels, and other valuable products. Photosynthesis occurs inside the cells, in structures ca.....»»
Brazil vows more aid as Amazon waters dry up
Brazil's Vice-President Geraldo Alckmin said Wednesday that more help would be sent to an Amazon state where rivers are drying up in a severe drought, causing mass die-offs of fish and dolphins......»»
Paint drops form “fried egg” patterns if concentration, temp is just right
Key insights into influential factors could lead to better control of drying process. Enlarge / As paint drops dry, they can look like a “fried egg” (left) or develop a more even pigment distribution (right). (credit: S.M.M......»»
Guest commentary: A look at two unions with common goals in Detroit 3 negotiations
Former Unifor President Jerry Dias: "I honestly would have believed that hell would freeze over before the UAW would strike with what we settled for here in Canada.".....»»
Indian spacecraft heads towards center of solar system
India's sun-monitoring spacecraft has crossed a landmark point on its journey to escape "the sphere of Earth's influence", its space agency said, days after the disappointment of its moon rover failing to awaken......»»
Did animal evolution begin with a predatory lifestyle?
Were the first animals predators or filter feeders like the sponges living in today's oceans? And what role did symbiosis with algae play, as with reef-building corals? Surprising findings by a research group led by Prof. Dr. Thomas W. Holstein of He.....»»
Ethics rules needed for human research on commercial spaceflights, panel says
New guidelines are needed to assure that research on human subjects performed on commercial spaceflights is conducted ethically, a panel of experts say in a commentary appearing in the September 28 issue of the journal Science. Their paper is titled.....»»
Study reveals how marine bacteria combat algae
Algae and bacteria are inseparable in ocean ecosystems, with bacteria playing a crucial role in regulating the growth and metabolism of algae. In addition to mutualism, bacteria have developed various molecular-based strategies to combat algae......»»
Top crypto marketplace hacked after cloud provider attacked
Mixin Network loses $200 million as operators freeze deposits and withdrawals......»»
Thousands of California wells are at risk of drying up despite landmark water law
Even though California enacted sweeping legislation nearly a decade ago to curb excessive agricultural pumping of groundwater, new research predicts that thousands of drinking water wells could run dry in the Central Valley by the time the law's rest.....»»
Video: Student engineers develop early warning system for blue-green algae
With temperatures rising due to global warming, blue-green algae blooms have become increasingly common on Alberta lakes. Early detection is crucial because the algae produce toxins that can be harmful to humans and animals......»»
Polar experiments reveal seasonal cycle in Antarctic sea ice algae
In the frigid waters surrounding Antarctica, an unusual seasonal cycle occurs. During winter, from March to October, the sun barely rises. As seawater freezes it rejects salts, creating pockets of extra-salty brine where microbes live in winter. In s.....»»
Toxic algae blooms are the new normal as CO2 levels keep rising
Ponds, rivers, and lakes all over are getting hit by blooms of blue-green algae. Enlarge / An algal bloom clogging a waterway near Lough Neagh in Northern Ireland. (credit: Chris Banaiuk) Standing on the marina, Rob Skel.....»»
How did plants first evolve into all different shapes and sizes? We mapped a billion years of plant history to find out
Plants range from simple seaweeds and single-celled pond scum, through to mosses, ferns and huge trees. Paleontologists like us have long debated exactly how this diverse range of shapes and sizes emerged, and whether plants emerged from algae into m.....»»
