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......»»
Microplastics have infected critical Arctic ice algae
A critical component of the food web in the Arctic is at risk. According to a new study published in the journal Environmental Science and … The post Microplastics have infected critical Arctic ice algae appeared first on BGR. A crit.....»»
A Critical Arctic Organism Is Now Infested With Microplastics
The algae Melosira arctica is the foundation of the food chain, and its contamination could have major consequences for ecosystems and the climate......»»
Arctic ice algae heavily contaminated with microplastics, reports new research
The alga Melosira arctica, which grows under Arctic sea ice, contains ten times as many microplastic particles as the surrounding seawater. This concentration at the base of the food web poses a threat to creatures that feed on the algae at the sea s.....»»
Using solar farms to generate fresh desert soil crust
In the arid regions of the American Southwest, an unseen world lies beneath our feet. Biocrusts, or biological soil crusts, are communities of living organisms. These industrious microbes include cyanobacteria, green algae, fungi, lichens, and mosses.....»»
Sea ice algae on which Arctic animals rely under threat from climate change
Sea ice algae is an essential resource for the survival of many species living in the Arctic......»»
Study shows diatoms provide an attractive habitat for bacteria
Single-celled algae and marine bacteria live in a complex but largely unexplored relationship. Now, a new study shows that the surface of diatoms is a surprisingly diverse habitat for bacteria. A team from the University of Oldenburg was able to demo.....»»
Feces from coral-eating fish may act as "probiotics" for reefs
Until recently, fish that eat coral—corallivores—were thought to weaken reef structures, while fish that consume algae and detritus—grazers—were thought to keep reefs healthy. But scientists have discovered that feces from grazers leave large.....»»
Integrative morphological and molecular assessment reveals diversity of Gracilariaceae algae in China
Gracilariaceae are economically and ecologically important red algae found worldwide that are used to produce agar. Although Gracilariaceae diversity in China has been well described in morphological studies, molecular phylogenetic studies are rare......»»
"Snowball Earth" might have been rather slushy: Study
Millions of years ago, the Earth was so cold that most of its surface was covered in ice. But that hard freeze might have been slushier than once thought......»»
Ocean warming intensifies viral outbreaks within corals
The breathtaking colors of reef-building corals come from photosynthetic algae that live inside the corals. A groundbreaking three-year study has found that viruses may increase their attacks on these symbiotic algae during marine heat waves......»»
How to Make A Unique “Rewrite” Clock With Arduino, CNC, And Sequins
This project is a continuation of my quest to build a robotic clock that can write and rewrite the time continuously, day in and day out. My first attempt, Doodle Clock, was a failure due to the marker drying up. Doodle Clock #2 failed because.....»»
Unwanted visitor ruins spring break in Florida—toxic algae
With its brilliant sun, white sand and turquoise water, Lido Key Beach would make for a perfect postcard of Florida beaches if it weren't for the dozens of dead fish lying on the shore, killed by a toxic algae bloom known as red tide......»»
Earlier algae blooms, lingering toxins: Invasive species cause big changes to a lake"s microbial community
New research from University of Wisconsin–Madison scientists traces two tiny invasive species through their outsized effects on the water quality, algae blooms and toxic conditions in a Wisconsin lake......»»
Apple cutting costs with bonus payment changes, hiring freeze
Apple's efforts to cut costs has led it to extend its hiring freeze into more areas, a report claims, as well as making changes to how it doles out promotions and bonuses to employees.Apple ParkWhile other major names in tech are performing mass layo.....»»
Heart tissue heads to space to aid research on aging and impact of long spaceflights
Johns Hopkins Medicine researchers are collaborating with NASA to send human heart "tissue-on-a-chip" specimens into space as early as March. The project is designed to monitor the tissue for changes in heart muscle cells' mitochondria (their power s.....»»
Different coarse-grained contents affect mechanical characteristics of frozen soil under freeze-thaw cycles
Frozen soil in nature is a multiphase composite geomaterial consisting of mineral solid particles, ice crystals, unfrozen water, and porous air. In cold regions, the deformation properties of frozen soils with different coarse-grained contents change.....»»
Microscopic chalk discs in oceans play a key role in Earth"s carbon cycle by propagating viruses
A Rutgers-led team of scientists studying virus-host interactions of a globally abundant, armor-plated marine algae, Emiliania huxleyi, has found that the circular, chalk plates the algae produce can act as catalysts for viral infection, which has va.....»»
Use of algae to support sustainable fertilizer production
Research into algae that could support the sustainable production of biofertilizers has been published by Sheffield researchers. Agricultural challenges such as the sustainable supply of biofertilizers could be solved by new research showing how diff.....»»
Machine learning model speeds up assessment of catalysts for decarbonization technology from months to milliseconds
Next time you drive past farms or prairies and ponds on a rural road, look around. They are a rich source of biomass. That includes corn, soybeans, sugar cane, switchgrass, algae and other plant matter. These carbon-rich materials can be converted to.....»»
Researchers uncover how photosynthetic organisms regulate and synthesize ATP
ATP, the compound essential for the functioning of photosynthetic organisms such as plants, algae, and cyanobacteria, is produced by an enzyme called "chloroplast ATP synthase" (CFoCF1). To control ATP production under varying light conditions, the e.....»»
