Scientists have found that colloidal particle clusters exhibit beautiful and unexpected symmetry, obeying a simple mathematical principle. The discovery may have implications for understanding the atomic-scale structure of liquids and the properties of matter.
A new study suggests that human activities are a leading cause of warming in the troposphere and cooling in the stratosphere. The research team found that ozone depletion combined with greenhouse gas emissions accounted for most of the recent rise in the tropopause height.
A study has shown that using larger laser treatment zones can safely correct nearsightedness and astigmatism in patients with large pupils. Nearly 56% of patients achieved uncorrected visual acuity of 20/20 or better, while nearly 62% achieved the same level in patients with astigmatism.
Researchers found that the Hawaiian hotspot drifted southward between 47-81 million years ago, contradicting the traditional stationary plume theory. This discovery sheds light on terrestrial dynamics and raises fundamental questions about the mantle's role in controlling plate motions.
A study by geneticists from Stanford and Harvard Universities reveals that humpback, fin, and minke whale populations in the North Atlantic were much higher before commercial hunting. The researchers estimated that there were around 800,000 to 900,000 whales, contradicting previous whaling records.
Researchers have counted the number of proteins that help an egg cell divide, revealing a crucial difference in motor density between the two poles. This discovery has dramatic consequences for embryonic development and understanding cellular forces.
A new study by Cornell University professor David Levitsky found that college freshmen gain an average of 4.2 pounds in their first 12 weeks, with breakfast and lunch at all-you-can-eat dining facilities accounting for 20% of the weight gain. The study suggests that this phenomenon may be contributing to the rise in obesity among Ameri...
Scientists discover that community assembly history influences productivity-biodiversity relationships in natural ecosystems. Experimental study with microorganisms reveals that the sequence of species arrival affects these relationships, which is a key factor in understanding diversity patterns.
Researchers have found that a species of micro-organism, Sulfolobus, has genetic differences between samples from the US, Eastern Russia, and Iceland. This challenges the long-held view that micro-organisms do not differ by geographic location.
Researchers found that recombinant interferons were effective against SARS-CoV replication, with interferon beta showing prophylactic protection and antiviral potential. Interferon alpha was less effective but could be a potential drug of choice in combination with other antiviral drugs.
A new microdialysis probe can detect cytokine markers indicating early infection or rejection responses to implants. This detection method aims to bioengineer the site for optimal device performance, ultimately benefiting public health and economic development.
Researchers identify key genes and cellular pathways contributing to schizophrenia, providing new insights into the disorder's complex biology. The study's findings hold promise for developing novel therapeutic strategies.
Researchers at OHSU found significant differences in free-base nicotine levels among 11 commercial cigarette brands, with some containing up to 36% free-base nicotine. The study's findings have implications for understanding the addictiveness of different tobacco products and may guide future research.
The $18 million SALT Observatory is nearing completion and will feature the largest optical telescope in the Southern Hemisphere. The observatory's primary scientific instrument, a spectrograph, will break light down into its constituent wavelengths to study stars and galaxies outside of the Milky Way.
The study provides strong support for the popular cold dark matter model of the universe, suggesting that galaxies are surrounded by massive, three-dimensional halos. The team measured the shapes of over 1.5 million distant galaxies using weak gravitational lensing, revealing that dark matter halos extend far beyond visible stars.
Combining herbal supplements with regular medication without consulting a doctor can lead to adverse interactions. Patients should discuss their herbal supplement use with their primary physician to ensure safe treatment and prevent unexpected complications.
A recent study found that 15% of African-American youths at risk of dropping out of school reported carrying a gun, with regular carriers more likely to be involved in selling drugs or fighting. The study suggests that carrying a gun may indicate a more serious pattern of behavior, rather than just another risk factor.
A new study measures the emotions of doctors-in-training, finding that anxiety, guilt, and compassion are prevalent feelings. The research highlights the importance of acknowledging and managing these complex emotions to improve medical education and patient care.
Researchers suggest that hydrothermal vent systems like Lost City could have supported early life due to their stability and chemical composition. The systems' ability to produce heat, minerals, and organic compounds for millions of years may have improved the chances for life to emerge and be sustained.
Researchers discover a new class of proteasome inhibitors that change the shape of the protein-digesting enzyme, leading to reduced activity and selective protein degradation. This finding has implications for treating diseases such as heart disease and cancer.
The study explores how older adults adjust their living environments to ensure comfort and flexibility, affecting their identity and well-being. By considering personal aspects of their surroundings, individuals can create a suitable space that accommodates their changing needs.
A study of 543 children found that exposure to violence between parents and harsh punishment are significant risk factors for adult partner violence. Child behavior problems, such as conduct disorder, also predict later relationship violence.
Scientists used an autonomous underwater vehicle to map two deepwater coral reefs, discovering well-developed reefs with nearly 100% living coral cover. The study provides new insights into the structure and composition of deeper coral reefs, which are essential for protecting commercial fisheries.
Researchers found that active involvement in forming an idea, known as generative learning, reduces false memory. Participants were more likely to accurately remember words from a list they created themselves than those presented by others.
A study by Harvard Medical School researchers reveals the subplate, a transient nerve cell structure, plays a crucial role in strengthening thalamic connections to the cortex and mapping out visual wiring patterns. Without it, defects in vision development can occur, such as cerebral palsy.
The WHO leader highlights three key priorities for action: reinstating health as a focus of organizational agendas, scaling up effective interventions to reach more dying children, and building capacity at the district level. Collaborative partnerships are necessary to achieve these goals and reduce child mortality worldwide by two-thi...
Scientists discover Lost City, the tallest hydrothermal vent system ever seen, which can persist for hundreds of thousands to millions of years. This discovery increases the chances of finding early life on the seafloor, with potential implications for life beyond Earth.
Researchers develop novel gene therapy platform using AAV to deliver galanin, a neuroactive peptide that suppresses seizure activity. The treatment reduces sensitivity to focal seizures in laboratory rats, offering hope for treating temporal lobe epilepsy patients.
A recent study found that genetic differentiation among Sulfolobus islandicus populations increases with geographic distance, contradicting the prevailing theory of microbial biodiversity. This discovery suggests a more diverse microbial world than previously predicted.
The study estimates that elimination of major risk factors would reduce disease burden by over 90% for diarrhoea, lower respiratory infections, and ischaemic heart disease. Global healthy life expectancy would increase by over nine years, with the largest gains in sub-Saharan Africa.
