In models that explore how humans act when their reputation is at stake, usually assumptions were made that are at odds with reality. In a new, more realistic model, scientists explore what happens when information is incomplete and people make mistakes. In their model, previously successful strategies do not lead to sustained cooperation, and in most cases do not evolve at all.
Facebook, Snapchat, and Instagram may not be great for personal well-being. The first experimental study examining use of multiple platforms shows a causal link between time spent on these social media and increased depression and loneliness.
Climate change is impacting the Caribbean, with millions facing increasing food insecurity and decreasing freshwater availability as droughts become more likely across the region, according to new research.
Alarming examples of the dangers from chemical weapons have been seen recently in the use of industrial chemicals and the nerve agent sarin against civilians in Syria, and in the targeted assassination operations using VX nerve agent in Malaysia and novichok nerve agent in the UK.
A new study found that 21 percentof the United States' greenhouse gas pollution (1.2 Pg CO2e year) could be removed through enhanced management of forest, grassland, agricultural, and coastal areas. An offset at this level would be the equivalent to pollution from every single US car and truck on the road.
Researchers have developed a wireless system that leverages the cheap RFID tags already on hundreds of billions of products to sense potential food contamination -- with no hardware modifications needed. With the simple, scalable system, the researchers hope to bring food-safety detection to the general public.
Researchers developed a versatile remote gaming interface that allowed experts as well as hundreds of citizen scientists all over the world through multiplayer collaboration and in real time to optimize a quantum gas experiment in a lab. Both teams quickly used the interface to dramatically improve upon the previous best solutions, that scientists had established after months of careful optimization. The experiment aims to unravel how humans solve complex, natural science problems.
Researchers have explored how renewable energy cooperatives have evolved. They have found that these cooperatives have developed a significant capacity to survive and adapt in response to the hostile context brought about by the economic and political regime.
The majority of consumers, even those who prefer online shopping, think the extinction of brick-and-mortar stores would be bad for society, according to a new study that explores consumers' perceptions of today's transforming retail environment.
Banks, pension funds and other institutional investors have a key role to play in efforts to avoid dangerous climate change. A limited number of these investors have considerable influence over the Amazon rainforest and boreal forests that are known 'tipping elements' in the climate system. Protecting these 'tipping elements' should be a priority for investors to help reduce both climate change and systemic financial risks created by it.
Computer algorithms are playing a growing role in analyzing hydrophone audio data when monitoring marine life, but human listeners can complement and enhance these algorithms. A project known as Orcasound has produced a web application that will enable citizen scientists to listen to livestreaming audio from hydrophones near the San Juan Islands.
