A recent NIH study suggests that taking short breaks can strengthen memories of new skills by solidifying them in the brain. Researchers found that volunteers' performance improved primarily during rest periods and not during practice, with gains correlating to changes in brain wave patterns.
A study on Spanish teen series reveals that audiences tend to favor male and female characters based on gender, with males being seen as 'rebels' and females as 'nice people'. The study highlights the need for more diverse and complex characters to break away from traditional stereotypes.
The first 'OSNAP' results show that deep water formation in the Labrador Sea plays a minor role in Atlantic Meridional Overturning Circulation (AMOC) variability. Instead, deep waters moving south through the abyssal basins east of Greenland dominate AMOC variability.
The study found a 16.1% decline in ICD placements not meeting Medicare coverage criteria at hospitals that settled with the DOJ, while non-Medicare patients also showed declines. Hospital-level variation remained, with top performers having less than 3.8% of ICDs not meeting criteria
A series of setbacks can lead to an 'action crisis,' causing individuals to question the importance of their goal. New research reveals that repeated struggles and setbacks can cause people to devalue their goal, making it harder to stick to it. However, knowing ahead of time when an action crisis may occur allows individuals to prepar...
Researchers found that species' phenology shifted four days earlier per decade after 1981, with increased synchrony between species pairs from 0.97 to 6.1 days per decade. However, the magnitude of shifts and correlations with temperature changes remain uncertain due to short time series and variations among species.
Canada's legacy in health is threatened by unacceptable Indigenous health disparities and a need for healthcare reform. The Lancet Series calls for bold action to address these challenges and ensure a sustainable health system for all Canadians.
A recent spike in homicide rates across the nation doesn't tell the whole story. According to a new UT Dallas study, long-term factors like segregation and poverty play a more significant role in increases than short-term fluctuations. The study found that most cities' homicide rates have remained relatively stable over time.
Researchers used Facebook ads targeted at users' personality traits, showing up to 1.4 times more clicks and 1.5 times more product purchases than non-targeted ads. The study suggests that psychological targeting is an effective approach to digital mass persuasion.
A new neuroendovascular technique called ADAPT has shown impressive 90-day outcomes for stroke patients with large-vessel clots. Approximately 58% of patients achieved a good outcome after thrombectomy using the direct-aspiration, first pass technique.
A new technique combines economics and volcano science to identify past eruptions from tree-ring temperature reconstructions, potentially pinpointing previously unknown eruptions. The method may help separate volcanic impacts on climate from random variability, informing policy and scientific applications.
The book series will be published in six electronic issues per year, featuring topical review articles covering present and future trends in modern chemical research. This format allows for faster indexing, discovery, and citation of contributions.
Researchers found that thinking of the future as now can motivate individuals to accomplish their goals. By considering deadlines in days instead of months or years, people are more likely to start working on their objectives. This shift in time metrics reduces procrastination and increases willingness to save for long-term goals.
The study found that Finland's temperature rose in two phases: from the 1930s to the late 1960s, and then faster from the 1970s onwards. The annual average temperature has risen by more than 2 degrees Celsius over the past 40 years.
Cyclone Narelle's intensity has steadily weakened as it moved southward towards Western Australia. TRMM satellite data showed falling cloud heights and weaker rainfall, indicating a significant decrease in the storm's power.
A new study reveals that consumers presented with options one at a time tend to be less satisfied and committed to their choices. The authors found that this is due to the uncertainty of future alternatives, leading to a feeling of hope that undermines satisfaction levels.
Center-pivot irrigation, invented in 1949, improves water distribution and reduces evaporation, resulting in more efficient farming. The technique is used worldwide, covering 20% of cultivated fields, which produce 40% of global food supply.
A new study led by Johns Hopkins University psychologist Amy Shelton found that people with better social skills are more proficient in taking another person's perspective, including spatial ones. This ability is crucial for those on the autism spectrum and may be related to empathy and tolerance.
Tropical Storm Songda has strengthened over the past few days, with maximum sustained winds reaching 69 mph. The storm is expected to continue intensifying, but its center will remain offshore from Luzon, Philippines. Gusty winds, heavy rainfall, and rough surf are forecast for the western side of the storm.
Researchers developed an innovative technique, Intelligent Outlier Detection Algorithm (IODA), to detect errors in sensitive technological systems. The algorithm can identify faulty readings or problems associated with failing sensors and isolate bad data.
Astronomers have identified the brightest source in the gamma-ray sky, with galaxy 3C 454.3 emitting flares 10 times brighter than its summer levels. The blazar's exceptional brightness is due to its orientation, with a jet aimed straight at Earth.
A new study published in Economic Inquiry explores how potential losers can use small concessions to successfully appease expected winners, but only under specific conditions. The researchers found that appeasement can be a good plan when choice is possible, and trade should be chosen over conflict.
The winners of the 2009 Science in Society Journalism Awards are Alison Bass, Jason Felch and Maura Dolan, Michael J. Berens and Ken Armstrong, and Pamela Ronald, who received $2,500 cash prizes for their investigative reporting on topics such as pharmaceutical industry manipulation, DNA-based forensic evidence, and genetic engineering.
Wei Biao Wu and Xiaofeng Shao's article, 'A limit theorem for quadratic forms and its applications,' presents a new statistical method for analyzing time series data. The researchers used a physical dependence measure to characterize time-series dependence, deviating from traditional approaches.
The Lancet Series on Health System Reform in China brings together scientific evidence on China's major health challenges and its health strategies. The series aims to foster collaboration between China, the World Health Organization, and international partners to strengthen the Chinese people's healthcare.
A study by the University of Tennessee investigates the temporal patterns and statistical persistence of total coliform bacteria in a stream. The research found that short-term persistence is dominated by runoff events, while longer-term persistence is likely related to baseflow, or groundwater supply.
Research suggests shifts in party control occur roughly every 14 years, with presidential and full cycle changes completing about every 26-28 years. The study provides a theoretical model for explaining these cycles and refines the understanding of national electoral realignments.
Researchers found that thinking about larger resource accounts makes consumption seem cheaper, leading to increased spending. This 'accessible account effect' applies to food, time, and other everyday purchases.
A University of Iowa professor suggests that word repetition, variations in word difficulty, and simultaneous learning of multiple words account for the vocabulary explosion in children. The researcher's computational simulations support this theory.
Researchers found that consumers tend to spend more money on brand-name items when someone they don't know is nearby. In contrast, consumers are more likely to buy cheaper items when no one is around. The study suggests that store owners can increase profits by optimizing product placement to minimize feelings of isolation or anxiety.
Researchers studied the plant's leaves, discovering an 'active snap-buckling instability' that controls rapid closure. The study reveals key mechanisms for the plant's trap-like movement, with implications for biomimetic systems and tiny artificial devices.
