EXPLAINER: How warming affects Arctic sea ice, polar bears
Majestic, increasingly hungry and at risk of disappearing, the polar bear is dependent on something melting away on our warming planet: sea ice......»»
How the loss of urban trees affects education outcomes
It's well established that urban tree cover provides numerous environmental and psychological benefits to city dwellers. Urban trees may also bolster education outcomes and their loss could disproportionately affect students from low-income families,.....»»
Most coastal Arctic infrastructure faces instability by 2100, study warns
A new study has produced the first map of all coastal communities and infrastructure across the Arctic, showing the vulnerability of the built environment to threats from climate change......»»
Building concrete on Mars from local materials
Imagine you've just gotten to Mars as part of the first contingent of settlers. Your first challenge: build a long-term habitat using local materials. Those might include water from the polar caps mixed with specific surface soils. They might even re.....»»
Protective salt marshes along coasts are in danger across the globe but it"s not too late to act, researchers say
Salt marshes are among coastal habitats endangered by both rising sea levels and urban development......»»
Arctic Wolf acquires BlackBerry’s Cylance endpoint security assets
Arctic Wolf and BlackBerry announced they have entered into a definitive agreement for Arctic Wolf to acquire BlackBerry’s Cylance endpoint security assets. Cylance is the pioneer of AI-based endpoint protection trusted by thousands of organization.....»»
Stem cell transplants could save the world"s corals, say researchers
Climate change is bleaching and killing off vast amounts of the world's coral due to rising sea temperatures. Dr. Benyamin Rosental of Ben-Gurion University of the Negev and his colleagues have proposed an out of the box potential solution: transplan.....»»
New study says we"re unlikely to find liquid water on Mars anytime soon
More than a hundred years ago, astronomer Percival Lowell made the case for the existence of canals on Mars designed to redistribute water from the Martian ice caps to its lower, drier latitudes. This necessarily meant the existence of Martians to bu.....»»
New climate chemistry model finds "non-negligible" impacts of potential hydrogen fuel leakage
As the world looks for ways to stop climate change, much discussion focuses on using hydrogen instead of fossil fuels, which emit climate-warming greenhouse gases (GHGs) when they're burned. The idea is appealing. Burning hydrogen doesn't emit GHGs t.....»»
What 92 years of data say about ice cover
Warming air temperatures are changing ice cover in seasonally frozen lakes worldwide. The timing of ice formation and melting, called ice phenology, affects lake temperatures, seasonal stratification, and lake ecology, though much about these dynamic.....»»
Shrinking wings, bigger beaks: Birds are reshaping themselves in a warming world
For wildlife, climate change is a bit like the "final boss" the protagonist faces in a video game: big, hulking and inescapable......»»
Rising drought frequency poses new threats to US wildlife, study finds
People around the world are dealing with drought, so it's not shocking that it affects wildlife, too: lack of moisture contributes to habitat loss, affects how animals compete for resources, and leads to dehydration and heat stress. The surprising pa.....»»
New data from "the last ice area" may help long-term conservation efforts in the Arctic
Earlier this year our international team of scientists from the Refuge Arctic consortium departed Iqaluit, Nvt. on a 56-day research expedition in the far north. We were sailing aboard the icebreaker CCGS Amundsen and our main objective was to study.....»»
Sea sponge-inspired microlenses offer new possibilities in optics
Beneath the ocean's surface, simple marine animals called sea sponges grow delicate glass skeletons that are as intricate as they are strong. These natural structures are made of a material called silica—also known as bioglass—that is both lightw.....»»
Buried landforms reveal North Sea"s ancient glacial past
An international team of researchers, including a glaciologist at Newcastle University, UK, has discovered remarkably well-preserved glacial landforms buried almost 1 km beneath the North Sea......»»
Satellites capture dramatic increase in HFC-125, a potent greenhouse gas
HFC-125 is a greenhouse gas becoming a major contributor to global warming, and in the first study to use satellites to measure its concentration in the atmosphere, researchers found it has increased exponentially in the past 20 years......»»
California researchers find sea otter population helps stop invasion of green crabs
Though sea otters are an unofficial mascot of Monterey County and popular among tourists and locals alike, they are also described as voracious predators that help keep problematic invaders out of coastal waters......»»
King tides are back and what they"re telling us
King tides return this weekend and with them a reminder of rising sea levels......»»
How much permafrost will melt this century, and where will its carbon go?
Among the many things global warming will be melting this century—sea ice, land glaciers and tourist businesses in seaside towns across the world—is permafrost. Lying underneath 15% of the northern hemisphere, permafrost consists of accumulating.....»»
Neural mechanisms of aggression reveal how fighting female flies focus on their foes
In most research labs, the scientists are on the same page about why they're pursuing a research project. But the Rubin Lab at HHMI's Janelia Research Campus isn't an ordinary research lab. The lab is examining how aggression affects vision in female.....»»
Study reveals complex bacterial dynamics of urinary tract infections
Urinary tract infections (UTIs) are a major widespread health issue that affects millions of patients globally every year. These infections are not only uncomfortable, but also challenging to treat, as they may often reoccur after the first infection.....»»
