Researchers at Georgetown University Medical Center have discovered both normal and abnormal liver stem cells, which may provide a new target for experimental treatment. The study found that blocking the stat3 gene was effective in preventing liver cancer in mice, opening up new possibilities for treating this devastating disease.
Researchers found that people feeling sad spend more money to acquire the same commodities as those in a neutral emotional state. This is because sadness and self-focus cause one to devalue possessions and increase willingness to pay for new material goods to enhance sense of self.
A study from Johns Hopkins Children's Center reveals alarming delays and lapses in emergency care among first-responders during child cardiac arrests, highlighting the importance of rapid response and basic life-saving techniques.
A study of pregnant women with preeclampsia found elevated levels of a peptide that raises blood pressure, potentially explaining its development. The researchers hope the findings may lead to treatment for preeclampsia by targeting specific tissues.
A Michigan State University physician reports the first nationally documented death from acute asthma caused by environmental tobacco smoke (ETS) in a bar employee. The case highlights the need for legal protections against ETS in workplaces, particularly for vulnerable employees with pre-existing conditions like asthma.
The European College of Neuropsychopharmacology (ECNP) offers a unique opportunity for young scientists to expand their knowledge and skills by working on scientific projects. The ECNP Research Grant for Young Scientists provides up to €50,000 funding for projects in neuropsychopharmacology or closely related disciplines.
The U.S. Department of Energy Joint Genome Institute has released an upgraded version of its IMG/M metagenome data management and analysis system, featuring five new metagenome datasets from recent studies on termite hindgut microbiota and TM7 microbe. The new system now contains 2,953 reference genomes.
A Northwestern University professor is studying rivers to understand how organic carbon is processed and consumed by microorganisms, revealing that it's a bigger component of global carbon cycling than thought. The study provides a framework for assessing these processes and sheds light on the internal cycling of carbon in rivers.
A study found that young women who increased their drinking during the high school-to-college transition were more likely to experience physical and sexual victimization. The majority of freshmen women did not experience any victimization, but those who drank alcohol had substantially higher rates of physical and sexual assault.
Researchers found that cognitive disfluency can be caused by both psychological and physical distance, leading to more abstract perceptions of the city. The study used italicized fonts and game Balderdash to demonstrate this phenomenon.
A study by University of Leeds researchers found that human psychology and automatic pilot can compromise data security. Employees tend to oversimplify risks and fail to consider consequences, leading to errors. To improve security, organisations should design systems with user involvement and implement triggers for critical thinking.
Researchers have discovered a moss protein that may play a crucial role in preventing Alzheimer's disease. The study found that the moss protein has an evolutionary conserved function with human presenilin, suggesting that it may provide clues to its primary role in mammalian systems.
Researchers from Uppsala University found that the body-centered cubic crystal structure of iron in the inner core explains seismic wave patterns. This discovery may impact our understanding of the earth's heat balance and magnetic field stability, opening new perspectives for studying the earth's past, present, and future.
Researchers at Stanford University have created nanoscale drums that can resonate in the same way, despite having different shapes. This discovery has implications for spectroscopy and may lead to new designs for computer chip circuits.
Scientists from PNNL found that split oxygen atoms exhibit unexpected chemical behavior on reduced titanium oxide surfaces. The team discovered that one oxygen atom stays in place while the other shimmies away, likely stealing energy from the stationary one.
This special issue examines homicide rates across various countries and cultures, highlighting factors such as alcohol consumption, economic inequality, and neighborhood-level factors. The study provides insights into the complex relationships between homicide rates and these variables.
A recent study found that gadolinium-containing contrast agents can cause allergic-like reactions in premedicated patients, including children and adults. Pre-medication with corticosteroids and antihistamines may not completely eliminate the risk of breakthrough reactions.
