Harsh out of necessity

In a study, MS patients showed more severe moral judgments than average, even in neutral conditions, attributing negative emotions to external causes. This 'externally oriented thinking' helps them minimize damage but also leads to an inability to reflect on emotions and identify real causes of their negative emotional state.

Rare disease gene has a key role in chronic hepatitis C infection

A recent study published in PLOS Pathogens identifies a host gene involved in the formation of Hepatitis C virus particles. The gene, ABHD5, regulates the efficiency of virus assembly and release from human host cells. High levels of ABHD5 expression lead to fewer lipid droplets, while lower levels result in their accumulation.

Stem cells know how to open up and unwind

Research found that heterochromatin organisation in embryonic stem cells is maintained in an open form through the action of key stem cell factors. This open architecture may contribute to keeping stem cells unspecialised and full of developmental potential.

Want to eat better? Sorry, we're closed

Research from Ohio State University found that stores in low-income areas are often closed too early, limiting access to healthy food options. The study suggests that extended store hours and transportation services could help meet consumers' needs.

Gene therapy halts pulmonary hypertension progression in large animal pre-clinical study

Scientists used gene therapy to halt pulmonary hypertension progression in a large animal model. The approach delivered SERCA2a gene via aerosol inhalation, slowing vascular changes and improving heart function. Further studies are needed to assess long-term efficacy and safety before human clinical trials.

Are we alone? Setting some limits to our uniqueness

A new paper uses exoplanet discoveries to estimate the probability of advanced life evolving on habitable planets. The authors find that unless the odds are extremely low, humanity is likely not the universe's first technological civilization. They calculate a 'pessimism line' below which human uniqueness would be impossible.

Underwater archaeology looks at atomic relic of the Cold War

The article discusses the recent declassification of documents on the USS Independence, a World War II aircraft carrier used as a target in the first atomic bomb tests. The documents provide insight into the ship's post-Bikini history, including radiation levels and decisions to remove contaminated fuel oil.

Why fraternal twins run in families

Researchers identified two genes associated with twinning, including one linked to higher levels of FSH that may lead to multiple eggs being released at once. The findings have implications for infertility treatments and may help predict how women respond to fertility treatments.

Ocean views linked to better mental health

A study by Michigan State University found that residents with ocean views experience significantly lower levels of psychological distress compared to those with green space. The researchers suggest that blue spaces may have a calming effect on the mind, while human-made areas in green spaces may not.

Friends 'better than morphine'

Research at University of Oxford found that individuals with more friends have a higher pain tolerance due to increased endorphin release, which promotes social bonding and pleasure. Additionally, the study discovered correlations between fitter people, those with higher stress levels, and smaller social networks.

WSU researcher improves mental health evaluations

A new assessment tool has been developed to gauge the risk of patients with mental illnesses committing crimes, improving upon the current evaluation system. The tool aims to strike a balance between patient rights and freedoms and public safety, facilitating quicker evaluations and hospitalizations for high-risk patients.

Science news story on Sci-Hub provides detailed view of user base; related editorial

A recent study on Sci-Hub usage reveals that the site's millions of users are scattered across the globe, with significant activity detected in China, India, and Iran. The study also highlights the unintended consequences of Sci-Hub's illegal paper acquisition methods, including the impact on libraries and scientific communities.

Bearded dragons show REM and slow wave sleep

Scientists have discovered REM and slow-wave sleep in bearded dragons, a finding that suggests brain sleep dates back at least to the evolution of amniotes. The study's authors believe that this common origin is more plausible than convergent evolution, given the early branching out of reptiles.

Personal cooling units on the horizon

Researchers at Penn State have developed a nanowire array that can cool about 5.5 degrees Fahrenheit using 36 volts, an electric field level safe for humans. The material is flexible, can be powered by a 500g battery pack for two hours, and could potentially be incorporated into firefighting gear or athletic uniforms.

A long-noncoding RNA regulates repair of DNA breaks in triple-negative breast cancer cells

A new study has identified a long non-coding RNA that plays a crucial role in the repair of DNA breaks in triple-negative breast cancer cells. The research found that blocking this RNA significantly increases sensitivity to radiation therapy, providing new insight into the biology of this tough-to-treat breast cancer subtype.

How cancer cells escape from tumors and spread

Cancer cells' ability to slide past obstacles and travel out of primary tumors is enabled by abnormal protein fiber scaffolding and the agility of cancer cells themselves. The researchers developed a model environment that mimics protein fibers, allowing them to observe and quantify the behavior of breast cancer cells.

Junk-food junkies go healthy when rewarded

Researchers at Cornell University found that consumers who have poor eating habits benefit most from long-term reward incentives for healthy food choices. In contrast, healthy eaters are more likely to purchase less healthy items when offered price breaks.

Insect outbreaks reduce wildfire severity

A University of Vermont-led study finds that insect outbreaks, such as mountain pine beetle and western spruce budworm infestations, significantly reduce wildfire severity. This contrasts with popular attitudes linking the two, and provides new insights for forest management and policy applications.

Brain cells divide the work to recognize bodies

Researchers from KU Leuven measured individual brain cell responses to animal and human body images, finding that each cell specializes in recognizing specific features. The findings suggest a collaborative process where different cells work together to recognize bodies.

How we understand others

A recent study examined the relationship between empathy and understanding others' mental states. The findings suggest that people who tend to be empathic do not necessarily understand other people well at a cognitive level. Social skills seem to be based on multiple abilities that are independent of each other.
