Researchers at Binghamton University have developed a new manufacturing approach to reduce solar energy costs using continuous electronic sheets and roll-to-roll processing techniques. The hybrid material enables high-quality production with lower costs, making it competitive with silicon-based products.
Researchers found that people who watched videos of someone else performing simple actions were more likely to falsely remember doing the same action themselves two weeks later. This phenomenon, known as observation inflation, may be due to internal simulation of what others are doing while observing them.
Researchers found that early cotton planting boosts yield only with irrigation. In non-irrigated plots, early planting resulted in decreased production, even experiencing a 13% decline in yield one year.

This finding raises questions about the influence of science on public policy debates.
Researchers analyzed text messages sent on September 11, 2001 to track emotional reactions. They found spiking anxiety in the morning and increasing anger throughout the day. The study suggests that anger dominated immediate reactions, which may explain consequences of the attacks.
Passengers in developing countries face a 13 times higher risk of being killed in an air accident than those in First World countries. The study also reveals that even the most economically advanced developing-world countries have seven times the death risk per flight as First World countries.
A recent study found that girls who experienced an insecure attachment to their mother at a young age tend to develop earlier and have their first period sooner. This is because an unstable environment can lead to accelerated pubertal maturation as an evolutionary adaptation to increase reproductive chances.
Researchers have successfully improved the ability of zinc oxide solar cells to absorb visible light using a blended mixture of off-the-shelf dyes. The best result came from a blend that boosted efficiency by nearly eight percent, paving the way for custom dye blends to be formulated for specific solar cell applications.

Researchers found that smokers who try to suppress their thoughts of smoking tend to smoke more than usual when they stop, a phenomenon known as behavioral rebound. This suggests that techniques like thought suppression may not be effective in quitting smoking and could even lead to increased consumption.
A new study suggests that people with a strong fusion of identity with their group will take extreme actions to protect others within the group, but not outsiders. Researchers found that those who identified as fused were more likely to sacrifice themselves for their own group members.
Children as young as 3-4 years old use statistical information to infer the preferences of others. In experiments, they were more likely to give a toy to someone who had selected it from a container with a low proportion of that toy type. This ability is crucial for learning about others' desires and preferences.
A recent study published in Psychological Science discovered that individuals who face restrictions on emigration tend to rationalize their country's system and justify its flaws. This reaction is linked to feelings of system inescapability, particularly among those experiencing poverty.
Researchers found that fields amended with poultry litter can accumulate significant levels of arsenic, which can then migrate into nearby streams and rivers. The study highlights the importance of controlling point sources of arsenic and suggests management practices to protect local regions from agricultural pollutants.
A new study by INFORMS suggests that persuading influential medical centers to adopt electronic medical records can accelerate the adoption of these systems among neighboring hospitals. The research found that targeting well-known, larger, and older hospitals in densely populated regions can significantly increase the rate of adoption.
A study of over 2,000 business units found that employee work perceptions predict important organizational outcomes. Employee job satisfaction is linked to higher retention rates, increased customer loyalty, and better financial performance.
A new study found that angry individuals pay more attention to rewarding images than threatening ones. This suggests that anger is associated with a motivation to approach rewards, rather than avoid threats. The research highlights the importance of understanding how emotions influence visual attention and behavior.

New research on Martian rocks suggests they may hold evidence of living organisms from 4 billion years ago. The findings provide a promising lead for future exobiology missions and shed light on the potential for life on early Mars.
Researchers found that people who stay busy, even with meaningless tasks, are happier than those who sit idly. The study used a survey with two options: drop off the survey at a nearby location or wait out the remaining time by walking to a farther location.
A study by Stanford University researchers found that individuals are more likely to speak up against bias when they hold the belief that people's personalities can change. This implies that confronting prejudice may be an expression of hope and a desire for personal growth, rather than simply a conflict situation.
Recent advances in computing have improved fluid modeling for low Reynolds numbers, but significant challenges remain for high-Reynolds-number flows, crucial in aeronautics and climate modeling.
Scientists at the University of Reading in the UK have created a kite-based system to measure wind speed with high accuracy.
