Research suggests that heightened risk taking during adolescence is driven by conflicting brain systems. The socioemotional system becomes more assertive during puberty, while the cognitive-control system matures later. This leads to a vulnerability window in teens where impulsive behavior can be triggered.
Scientists used a magic trick to investigate how magicians manipulate our perception by exploiting social cues and expectations. They found that observers perceived the ball leaving the magician's hand due to cues from the magician's head direction, but not when it was no longer present in the illusion.
New radiocarbon dating reveals Maui's temples were built in cycles with warfare and island consolidation, shifting from open-air ancestral worship to elaborate sacrificial offerings. The findings provide insight into the economic, political, and ritual development of ancient Hawaiian civilization.
This study found that online file-sharing communities, like Napster, exhibit self-imposed rules and symbolisms, similar to traditional gift systems. Online networks have a greater scale and non-sacrificial gifts, providing an alternative consumer-centric model of contemporary gift-giving.
The article examines three common Social Security reform proposals and their impact on vulnerable women. The analysis reveals that privatization proposals fail to cover significant numbers of poor women, while benefits tied to U.S. residency or simple Social Security eligibility are more effective at protecting them.
A recent study by Scott W. Allard found that the welfare-to-work system is struggling to meet the needs of growing areas of poverty, which are increasingly geographically dispersed. The mismatch between service providers and populations in need may worsen under work-first welfare policies.
The Virginia Tech National Bioinformatics Resource Center will focus on Brucella, Caliciviruses, hepatitis A, Rabiesvirus, and Coxiella burnetii/Rickettsias. The center will enable researchers to access, analyze, and study molecular data for these infectious diseases.
Researchers found that nearly one-quarter of hospitalized individuals with current alcohol use disorders had undetected diagnoses, and only half of detected cases received intervention or treatment referral. The study highlights the need for routine screening and education among medical professionals to address this issue.
Research suggests that social structures in insects like bees and ants emerge from group interactions, with patterns of behavior creating complexity. This idea challenges the conventional view that social characteristics are programmed by genes, proposing instead that adaptation follows the development of networks.
A recent study by Kansas State University researchers found that birds cheat on their mates to avoid inbreeding and increase genetic diversity. In a collaborative study of three shore bird species, the team discovered that infidelity rates are significantly lower than those observed in songbirds.
Adam Davis's work focuses on integrating economic value into land conservation for private landowners, using current regulations to drive the economic value of conservation. Companies are finding that investing in protected environments is not only good for the Earth but also a sound financial investment.
Researchers found that Tsavo lions live in large groups of females ruled by a single male, with an average of 7.4 adult females per group. The study suggests that the lions' manelessness may be an adaptation to their hot and dry environment.
Researchers developed a conflict early warning system to predict instability in countries like Afghanistan and Pakistan. The tool uses numerical scores based on civil contention, state repression, and violence to indicate a country's stability.
Researchers found that viewers who watched uncivil debates on TV showed more negative attitudes toward Congress, politicians, and the American political system. Civility in debates had a positive impact on viewer recall of arguments, but hostile exchanges led to de-legitimization of opposing opinions.
The Pittsburgh Supercomputing Center will develop a six-teraflop terascale system, making it the most powerful available for public research. The system, part of NSF's PACI program, aims to facilitate progress in various fields, including climate change and weather forecasting.
A team of researchers at Sandia National Laboratories has developed an intelligent software agent that can defend itself and other computers against cyber attacks. The agent uses a multi-agent collective approach to detect and respond to unusual requests or commands, providing real-time protection against various types of threats.
Applause dynamics studied using physics principles reveal social self-organization and synchronization processes. Researchers found that individual clapping frequencies play a crucial role in achieving synchronization, leading to increased volume and decreased noise intensity.
UT Southwestern Medical Center investigators have developed a rare case of familial filicide in which twin sisters tried to kill their own children. A new classification system, identifying 16 subtypes of filicide, aims to aid understanding and strategies for prevention.
The Cornell researchers will examine new operating rules for the system and the effects of alternative market structures using a simulated Northeast electricity grid and laboratory experiments. They aim to strike a balance between ideal market mechanisms and traditional utility practices while maintaining system stability and reliability.
Archaeologist Stanley Ambrose's findings from the Enkapune Ya Muto rock shelter in Kenya suggest that modern human behavior emerged around 40,000 years ago. The discovery of stone tools and ostrich eggshell beads indicate an early form of social solidarity and adaptive technology.
Janet Randall deciphered the communication system used by great gerbils to warn their kin of danger, discovering a variable warning system that alerts family members to the degree of risk. The gerbils' altruistic motives contrast with those of kangaroo rats, which use foot-drumming to ward off predators.
The Great Lakes Geriatric Interdisciplinary Team Training project brings together health care workers and their patients into teams to identify physical, social and economic needs. The goal is to provide high quality health care while controlling costs by keeping patients at home longer or helping them follow medical care better.
Six American institutions are putting ancient manuscript collections online through the Advanced Papyrological Information System (APIS), making fragile materials accessible to scholars worldwide. The effort aims to digitize and link images, texts, and bibliography for easier research.
