The impact of energy development on bird populations
The greater sage-grouse is an iconic bird that lives in the western United States, and its populations are in decline. A new study published in the Journal of Wildlife Management reveals that energy development has negative impacts on sage-grouse reproduction.
Thinking in acids and bases
Researchers from the National Institute for Physiological Sciences in Okazaki designed and tested a probe to track brain pH in mice during a visual task. The new proton image sensor has increased spatial and temporal accuracy compared with previous techniques, and revealed distinct patterns of pH changes in the primary visual cortex that were induced by different stimulus patterns, making it a...
Topology protects light propagation in photonic crystal
Researchers of AMOLF and TU Delft have seen light propagate in a special material without it suffering from reflections. The material, a photonic crystal, consists of two parts that each have a slightly different pattern of perforations. Light can propagate along the boundary between these two parts in a special way: it is topologically protected and, therefore, does not bounce back at...
Types of vaping products used by hospitalized patients with severe lung injury
This report describes the kinds of vaping products used by and the clinical characteristics of patients hospitalized in California last year with e-cigarette or vaping-associated lung injury.
Unwanted behavior in dogs is common, with great variance between breeds
All dog breeds have unwanted behavior, such as noise sensitivity, aggressiveness and separation anxiety, but differences in frequency between breeds are great. Various unwanted behavior traits often occur simultaneously, as indicated by a study recently completed by Professor Hannes Lohi's research group from the University of Helsinki.
Using technology during mealtimes may decrease food intake, study finds
When 119 young adults consumed a meal while playing a simple computer game for 15 minutes, they ate significantly less than when they ate the same meal without distractions, said lead author Carli A. Liguori, an alumna of the University of Illinois at Urbana-Champaign's food science and human nutrition program.
West coast dungeness crab stable or increasing even with intensive harvest, research shows
Fishermen from California to Washington caught almost all the available legal-size male Dungeness crab each year in the last few decades. However, the crab population has either remained stable or continued to increase, according to the first thorough population estimate of the West Coast Dungeness stocks.
What women really want
Earlier research purported to show links between a woman's cycle and how attracted she was to men's behavior. Research at the University of Göttingen questions this. It showed shifts in women's cycles did not affect their preferences for men's behavior. Researchers found, however, that when fertile, women found all men slightly more attractive. Irrespective of their cycle, flirtier men were...
World-first system forecasts warming of lakes globally
Pioneering research led by the UK Centre for Ecology & Hydrology (UKCEH) has devised the first system that classifies lakes globally, placing each of them in one of nine 'thermal regions.' This will enable scientists to better predict future warming of the world's lakes due to climate change, and the potential threat to cold-water species such as salmon and trout.
'More scary than coronavirus': South Korea's health alerts expose private lives
‘Safety guidance texts’ sent by the authorities contain an avalanche of personal information and are fuelling social stigmaCoronavirus latest updatesAs the number of coronavirus cases in South Korea exceeded 6,000 this week, there was a rise, too, in complaints about information overload in the form of emergency virus text alerts that have included embarrassing revelations about infected...

From "flat Earth" to climate denial, kids are deluged with fake science
"It's a big issue that goes way beyond science education," one educator...
South Korea has tested 140,000 people for the coronavirus. That could explain why its death rate is just 0.6% — far lower than in China or the US.
Experts have suggested that coronavirus death rates could decrease as more mild cases are...

Tapping into 35 years of satellite imagery, researchers have dramatically enlarged the database regarding how climate change is affecting kelps, near-shore seaweeds that provide food and shelter for fish and protect coastlines from wave damage.
Food scientists slice time off salmonella identification process

- 20/3/6 02:35
An international team of scientists has launched a comprehensive overview of all proteins expressed in the brain. The open-access database offers medical researchers an unprecedented resource to deepen their understanding of neurobiology and develop new, more effective therapies and diagnostics targeting psychiatric and neurological diseases.
Downsizing the McMansion: Study gauges a sustainable size for future homes

A new scholarly paper assesses a big factor in the needed transformation of our living spaces toward sustainability -- the size of our homes.
Scientists monitor brains replaying memories in real time
- ScienceDaily
- 20/3/6 02:35
In a study of epilepsy patients, researchers monitored the electrical activity of thousands of individual brain cells, called neurons, as patients took memory tests. They found that the firing patterns of the cells that occurred when patients learned a word pair were replayed fractions of a second before they successfully remembered the pair.
More accurate climate change model reveals bleaker outlook on electricity, water use
- ScienceDaily
- 20/3/6 02:35
A new model more accurately captures how climate change will impact electricity and water use. The researchers recommend that city planners use the model now to better evaluate potential risk of power shortages and blackouts.

Hedgehog numbers are declining in part because so many are killed while crossing our roads.
Limited coronavirus testing in the US has meant its death rate appears alarmingly high — but it will likely drop
