Marine bacteria in Canadian Arctic capable of biodegrading diesel and oil
Marine bacteria in the frigid waters of the Canadian Arctic are capable of biodegrading oil and diesel fuel, according to a new study published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology......»»
Arctic sea ice near historic low; Antarctic ice continues decline
Arctic sea ice retreated to near-historic lows in the Northern Hemisphere this summer, likely melting to its minimum extent for the year on Sept.11, 2024, according to researchers at NASA and the National Snow and Ice Data Center (NSIDC). The decline.....»»
Drone footage provides new insight into gray whales" acrobatic feeding behavior
Drone footage captured by researchers in Oregon State University's Marine Mammal Institute is offering new insight into the acrobatics undertaken by gray whales foraging in the waters off the coast of Oregon......»»
Bacterial "flipping" allows genes to assume different forms
Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called.....»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»
Better together: Gut microbiome communities found to have enhanced resilience to drugs
Many human medications can directly inhibit the growth and alter the function of the bacteria that constitute our gut microbiome. EMBL Heidelberg researchers have now discovered that this effect is reduced when bacteria form communities......»»
In the gateway to the Arctic, fat, ice and polar bears are crucial. All three are in trouble.
Searching for polar bears where the Churchill River dumps into Canada's massive Hudson Bay, biologist Geoff York scans a region that's on a low fat, low ice diet because of climate change......»»
Graphene spike mat uses ordinary fridge magnet tech to fight antibiotic resistance
With strong bactericidal properties, graphene has the potential to become a game changer in the fight against antibiotic-resistant bacteria. So far there have been no efficient ways to control these properties—and thus no way to make use of graphen.....»»
Shoreline access, lack of parking found to be obstacles to shared usage of coastal resources in Rhode Island
There are obstacles when it comes to sharing marine space, infrastructure, and resources in Rhode Island, a recent study found. With the usage of the state's coastal and offshore waters increasing, University of Rhode Island professor of marine affai.....»»
Our digital 3D models of huge coral reefs could help revive these precious ecosystems
As a team of marine biologists, assessing the health of thousands of square meters of coral reef can be a daunting prospect. Often, we have to monitor some of the most biodiverse ecosystems on the planet, and there's a strict time limit due to the sa.....»»
Chemists discover new ways in which single-celled organisms organize their DNA
It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that structure DNA. Now, Leiden Ph.D. candidate Samuel Schwab has found that the histones in these organisms are much more diverse.....»»
Deeper corals may help shallow reefs recover in the Florida keys
Since the 1970s, coral reefs in the Florida Keys National Marine Sanctuary (FKNMS) have experienced catastrophic declines in coral cover, with as much as a 50% reduction between 1998 and 2011 alone. Although coral reefs within the FKNMS have been hea.....»»
Phytoplankton shield ice shelves from summer heat
In spring, stretches of Antarctic sea ice melt to form pockets of open water called polynyas, which make perfect homes for phytoplankton. These marine microbes can become so abundant that they turn the water green......»»
Experts discover the deadly genetics of cholera, which could be key to its prevention
Experts have used a cutting-edge computational approach to discover the genetic factors that make the bacteria behind cholera so dangerous—which could be key to preventing this deadly disease......»»
AI tools help uncover enzyme mechanisms for lasso peptides
Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tes.....»»
Small "no-take zone" can help protect critically endangered hammerhead shark in Columbia
Researchers are advocating for a "no-take zone" off the coast of Colombia after one of the world's smallest and most threatened hammerhead species was found to do very little traveling outside of a Marine Protected Area in the region......»»
How a bacterial pathogen that causes dysentery manipulates molecular activity to assure its survival
Virginia Tech researchers have learned how bacteria manipulate molecules to infect the host organism. Daniel Capelluto and his research team have discovered the mechanism by which the bacterial pathogen Shigella flexneri, the causative agent of dysen.....»»
Magnetic micro spinbots can perform ultraprecise surface polishing and cleaning
A research team has unveiled an innovative technology for ultraprecision surface polishing and cleaning using simultaneously operating magnetic micro spinbots. These tiny robots, capable of nanometer-scale contaminant removal and polishing, offer a l.....»»
Arctic weather satellite"s first images capture Storm Boris
Just a month after its launch, ESA's Arctic Weather Satellite has already delivered its first images, notably capturing Storm Boris, which has been wreaking havoc across central Europe......»»
Scientists track plastic waste in pristine Canada marine park
Old tires, discarded cups, and cigarette butts litter the magnificent Saguenay Fjord, a marine protected area in eastern Canada that attracts belugas and other whales seeking respite......»»
How plastic pollution poses challenge for Canada marine conservation
One of the largest producers of plastic waste per capita, Canada is struggling to protect its designated marine protected areas from this pollution, experts warn......»»
