Climate change coping mechanism discovered in humble algae      (via sciencedaily.com)     Original source 

One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops.

Research shows wildfire smoke may linger in homes long after initial blaze      (via sciencedaily.com)     Original source 

Newly published research on indoor air quality shows wildfire smoke may linger in homes long after the initial blaze has been put out or winds have shifted. The findings show that wildfire smoke can attach to home surfaces like carpet, drapes or counters -- extending the exposure for those inside and potentially causing health problems even after an initial cleaning activity by air purifiers.

What phytoplankton physiology has to do with global climate      (via sciencedaily.com)     Original source 

Phytoplankton, tiny photosynthetic organisms in the ocean, play a crucial role in the global carbon cycle and influence Earth's climate. A new study reveals how variations in the physiology of phytoplankton, particularly regarding nutrient uptake, can impact the chemical composition of the ocean and even the atmosphere. This suggests that changes in marine phytoplankton physiology can affect global climate.

Over 40 percent of Antarctica's ice shelves reduced in volume over 25 years      (via sciencedaily.com)     Original source 

71 of the 162 ice shelves that surround Antarctica have reduced in volume over 25 years from 1997 to 2021, with a net release of 7.5 trillion tons of meltwater into the oceans, say scientists.  They found that almost all the ice shelves on the western side of Antarctica experienced ice loss. In contrast, most of the ice shelves on the eastern side stayed the same or increased in volume.  Over the 25 years, the scientists calculated almost 67 trillion tonnes of ice was exported to the ocean, which was offset by 59 trillion tons of ice being added to the ice shelves, giving a net loss of 7.5 trillion tons.

Large swings in past ocean oxygen revealed      (via sciencedaily.com)     Original source 

As the climate warms, there is major concern that Earth's ocean will lose oxygen. A study has revealed that locked in ancient deep-sea sediments is evidence for oxygen loss in the world's ocean during past glacial periods, indicating that widespread oxygen loss with current climate change may not be permanent.

Flooding that closed Alaska's Dalton Highway also caused widespread ground sinking      (via sciencedaily.com)     Original source 

The massive 2015 flooding of the Sagavanirktok River in northern Alaska had immediate impacts, including closure of the Dalton Highway for several days, but it also contributed to longer-term ground subsidence in the permafrost-rich region.

Rivers may not recover from drought for years      (via sciencedaily.com)     Original source 

Lack of rainfall is not the only measure of drought. New research shows that despite a series of storms, the impact of drought can persist in streams and rivers for up to 3.5 years.

Killer whales' diet more important than location for pollutant exposure      (via sciencedaily.com)     Original source 

Both elegant and fierce, killer whales are some of the oceans' top predators, but even they can be exposed to environmental pollution. Now, in the largest study to date on North Atlantic killer whales, researchers report the levels of legacy and emerging pollutants in 162 individuals' blubber. The animals' diet, rather than location, greatly impacted contaminant levels and potential health risks -- information that's helpful to conservation efforts.

Warm summers and wet winters yield better wine vintages      (via sciencedaily.com)     Original source 

Wine quality is notorious for varying from year to year, but what makes for a 'good year?' Researchers show that weather plays an important role in determining wine quality. By analyzing 50 years’ worth of wine critic scores from the Bordeaux wine region in relation to that year’s weather, the researchers showed that higher quality wine is made in years with warmer temperatures, higher winter rainfall, and earlier, shorter growing seasons—conditions that climate change is predicted to make more frequent.

Epiphytes, amazing plants like moss and bromeliads found in trees, face growing threats      (via sciencedaily.com)     Original source 

Epiphytes, plants such as orchids and mosses that grow in trees, draw nutrients from the air and create refuge for all sorts of other life forms. They are the foundation of forest canopy ecosystems, but they are facing threats from human and natural disturbances.

Discovery of invisible nutrient discharge on Great Barrier Reef raises concerns      (via sciencedaily.com)     Original source 

Scientists using natural tracers off Queensland’s coast have discovered the source of previously unquantified nitrogen and phosphorus having a profound environmental impact on the Great Barrier Reef. Groundwater discharge accounted for approximately one-third of new nitrogen and two-thirds of phosphorus inputs, indicating that nearly twice the amount of nitrogen enters the Reef from groundwater compared to river waters.

Newly-discovered 'margarita snails' from the Florida Keys are bright lemon-yellow      (via sciencedaily.com)     Original source 

A newly-discovered, bright yellow snail has been discovered in the Florida Keys and named in honor of Jimmy Buffet's song 'Margaritaville.' The lemon-colored marine snail, along with its lime-green cousin from Belize, is the subject of a recent study ; researchers think these snails' bright colors might help deter predators.

Early human migrants followed lush corridor-route out of Africa      (via sciencedaily.com)     Original source 

Scientists have found early human migrants left Africa for Eurasia, across the Sinai peninsula and on through Jordan, over 80-thousand years ago. Researchers have proved there was a 'well-watered corridor' which funneled hunter-gatherers through The Levant towards western Asia and northern Arabia via Jordan.
