A new study of 332 US manufacturing companies found that international joint ventures and multinational operations increase downside risk, contradicting common business wisdom. Domestic joint ventures also failed to reduce financial risks.
A new study by Stanford University researchers finds that global aquaculture production has more than doubled in the past 15 years, but it also adds to the world's supply of fish. However, the growing demand for carnivorous species like salmon and shrimp threatens the sustainability of ocean fisheries.
Researchers identified a working 'inhibitory synapse' between brain neurons and hair cells in the cochlea, suggesting a feedback mechanism that wires ears and brain for hearing. This discovery moves researchers closer to understanding human and mammalian hearing development.
Teenage girls with lactose intolerance can consume dairy products daily without discomfort, as they adapt to increased consumption over three weeks. The study's findings suggest that slowly adding dairy to the diet can help alleviate bloating and gas, while still meeting calcium needs.
Researchers solved the 'nug30' problem, a test of computer capabilities that challenged computer scientists for 32 years, by designing an efficient algorithm and leveraging high-performance computing resources. The solution demonstrates advancements in combinatorial optimization problems and their applications in real-world fields.
The structure of E. coli intimin-receptor complex shows how the bacterium attaches to intestinal cells, using a protein-protein complex with rigid arms and attaching hands. This finding could lead to new drug designs to thwart infection.
A new study from Ohio State University reveals that trade agreements between countries can significantly reduce the likelihood of military conflicts. Countries belonging to the same preferential trade arrangements (PTAs) were 30-45% less likely to become involved in military disputes, compared to those without such agreements.
Expansion of methadone programs would reduce the spread of HIV to the general population, resulting in significant health benefits. The study estimated that expansion of methadone treatment capacity would cost between $8,200 and $10,900 for every quality-adjusted life year gained.
Researchers use 18th-century formula to reconcile DNA study discrepancies and create more consistent picture of evolution's history. By considering all possible evolutionary trees, Bayesian mathematics allows for a more accurate understanding of the evolutionary history of life.
A study by researchers at Johns Hopkins and two other academic medical centers found that large fluctuations in eye pressure during the day or over consecutive days are associated with greater risk of vision loss. Glaucoma patients who experienced low fluctuations in pressure had a lower risk of further vision loss compared to those wi...
A three-year study of 351 people from Sweden aged 80 and over reveals that psychoactive medications have negative effects on cognitive performance. The results show that individuals taking these medications experience lower performance scores and a more severe decline in cognitive function compared to those not on medication.
Researchers have designed a molecule that selectively inhibits gelatinase enzymes, which help tumors grow and spread. This discovery may lead to new treatments for breast and prostate cancers, as well as other types of cancer and inflammations.
The National Science Foundation has awarded a $1.1 million research grant to the University of Alaska Museum to create the Arctic Archival Observatory, the first NSF-funded observatory of its kind in the U.S. The grant will enhance hands-on opportunities for graduate students and improve access to museum holdings.
Scientists at NIH and Whitehead Institute have grown malaria parasites in fruit flies, creating a model for studying parasite development in insects. The new model has identified a part of the insect immune system that naturally attacks malaria parasites.
