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......»»
Cyanobacterial blooms can also occur at colder temperatures, even under ice
Mass developments of cyanobacteria, so-called blue-green algae blooms, repeatedly threaten the quality of water bodies and drinking water resources worldwide. Cyanobacteria are considered to be heat-loving, and massive algal blooms are reported mainl.....»»
Snow algae: Investigating how algal blooms impact mountain snowpack
Scott Hotaling, an Assistant Professor in the Department of Watershed Sciences in the Quinney College of Natural Resources, is exploring how the watermelon-tinted blooms of snow algae impact mountain snowpack—where they come from, what triggers a b.....»»
How does a drying Great Salt Lake affect carbon cycling?
As water levels at the lake continue to decline, the complex natural systems the lake supports are shifting, too. Ecohydrologist Erin Rivers from the Quinney College of Natural Resources is investigating how shifting water levels at the Great Salt La.....»»

Study finds timing of drought is more damaging to invertebrates than severity
Populations of various species of aquatic insects and other invertebrates respond to flooding and waterway drying due to drought in different ways that can be anticipated, according to a new Penn State-led study that employed a novel method to assess.....»»
New species of ultrasmall microalgae found in home aquarium could have multiple useful applications
A new species of microalgae was found in water from a home aquarium. While analyzing DNA samples taken from the algae, researchers from the University of Tokyo discovered a DNA sequence that didn't match any on record. This new species is the smalles.....»»
Long, dense spikes on red algae-derived metal-polysaccharide show promise for anti-microbial applications
Antibiotic resistant bacteria are becoming more and more of a concern as traditional sources of anti-microbial treatments become less effective. Therefore, researchers at Ben-Gurion University of the Negev are looking farther afield for promising com.....»»
Humans found to have influenced the growth of blue-green algae in lakes for thousands of years
In recent years, there have been increasing reports of toxic blue-green algae blooms in summer, even in German lakes, caused by climate warming and increased nutrient inputs. But humans have had an influence on the development of blue-green algae sin.....»»
"Friend or foe" bacteria kill their algal hosts when coexisting is no longer beneficial
Scientists have detailed a lifestyle switch that occurs in marine bacteria, in which they change from coexisting with algae hosts in a mutually beneficial interaction to suddenly killing them. The results are published today in eLife......»»
Ransomware victims are refusing to pay, tanking attackers’ profits
The drying up of payouts is forcing attackers to hunt bigger game and re-extort. Enlarge / Holding up corporations, utilities, and hospitals for malware-encrypted data used to be quite profitable. But it's a tough gig lately, you.....»»
The Mesopotamian Marshes Are Disappearing, Again

Amid economic downturn, space investment plummeted in 2022
One reason is that investors may have been wary after the space SPAC crash. Enlarge / Sir Richard Branson took to the sky in the summer of 2021. But since then, with no additional spaceflights, Virgin Galactic's stock has taken a.....»»
Microalgae could be the future of sustainable superfood in a rapidly changing world, study finds
Algae. It's what's for dinner. This variation on the iconic US advertising slogan from the beef industry may sound funny, but it's no joke that the current agriculture system is a major source of greenhouse gas emissions and environmental pollution......»»
Study finds that UV-emitting nail polish dryers damage DNA and cause mutations in cells
The ultraviolet nail polish drying devices used to cure gel manicures may pose more of a public health concern than previously thought. Researchers at the University of California San Diego have studied these ultraviolet (UV) light emitting devices,.....»»
Research improves ability to identify and study algae species
Harmful algal blooms create challenges around the globe for water quality and health risk management for humans, wildlife and pets. A team of researchers from the University of Oklahoma is leading an effort toward better management of Microcystis blo.....»»
Scientists uncover coral-algae reward, punishment system
In human society, reward and punishment are introduced as an incentive to induce cooperation. However, some people still try to cheat to win. So, is there a system with clear rewards and punishments in the world of other organisms? The answer is "yes.....»»
Protecting biocatalysts from oxygen
Certain enzymes from bacteria and algae can produce molecular hydrogen from protons and electrons—an energy carrier on which many hopes are riding. All they need for this purpose is light energy. The major obstacle to their use is that they are des.....»»
After "22 low sales, "23 rebound uncertain

Methane emissions offset carbon uptake in Baltic macroalgae habitats
Bladderwrack in the Baltic Sea emits significant amounts of methane, which, to some extent, can offset the uptake of atmospheric carbon dioxide by these algae. This is shown by a new study from Askö Laboratory, where the fluxes of greenhouse gases b.....»»
Ailing manatees in Florida"s Brevard County appear to have outlasted Christmas freeze
