Researchers at the University of Illinois have developed an automated optical film-thickness measurement technique that is both inexpensive and nonintrusive. The technique uses light reflection to measure film thickness with an accuracy of one-hundredth of a millimeter.
A study by UCSF researchers found evidence of faulty DNA repair in some infertile men, similar to those with certain cancers. The study suggests that defective DNA repair may be a reason for male infertility and potentially increase the risk of offspring infertility and cancer.
A Yale study reveals that training low-income parents and inner city daycare teachers to engage three-to five-year-olds in make believe play can significantly strengthen children's skills for succeeding in school. This play-based approach enhances vocabulary, language usage, counting, fine motor control, and social/emotional growth.
Compton Gamma Ray Observatory's Burst And Transient Source Experiment (BATSE) discovered nearly 30 new exotic astrophysical objects and phenomena, rewriting astronomy textbooks. The instrument also contributed to 10 scientific prizes and 18 Ph.Ds.
Historical case of Eva Peron's secret surgery highlights the ongoing challenges of balancing medical care with social and political implications, according to Dr. Barron H. Lerner. Despite apparent openness in modern times, many confidential details remain hidden from public scrutiny.
Researchers discovered how brain fills in missing information to help us perceive objects, even when they're partially blocked. This process allows for consistency and continuity in our visual world, enabling us to recognize shapes and objects accurately.
A study by Kermyt Anderson found that stepfathers invest significant amounts of money and time in their stepchildren. Despite initial assumptions portraying stepfathers negatively, the research suggests they gain mating benefits and opportunities for lifetime reproductive success.
Researchers at Northwestern University found that adult memories of childhood events and relationships are no more accurate than chance, contradicting the idea that memory is a continuous tape. The study's findings have important implications for psychiatrists and mental health professionals who rely on patient reports.
Compressing coronary angiograms for delivery over telephone or computer lines can lead to diagnostic errors, according to researchers. Image quality is progressively lost with increasing compression, making it difficult for clinicians to detect subtle diagnostic features.
Researchers will discuss potential anti-cancer properties of selenium in broccoli and analyze human exposure to toxic chemicals through hair analysis. The meeting will also focus on the ongoing contamination of the Great Lakes by toxaphene, a pesticide banned in 1986.
A study found that the plasmin system, which regulates blood clots, may also play a role in Alzheimer's disease. The researchers suggest that destroying amyloid-beta protein deposits with tPA could be a potential treatment for the disease. Further research is needed to confirm this model and explore its effectiveness.
Researchers have found no evidence of gradual dinosaur extinction but rather a catastrophic event. Scientists also explore the formation of the Hawaiian volcanic Island of Hilo Ridge, which challenges previous theories on its origin.
Researchers found a significant increase in lobular breast cancer among postmenopausal women taking combined hormone-replacement therapy. The study reported a 2.6-fold increase in incidence among those who took the therapy for six months or more.
Scientists at the University of Illinois found that piezoelectric ceramics' properties decrease as they become thinner, affecting their performance in microelectromechanical systems. To optimize thin-film structures, researchers must understand the factors influencing material properties.
The Columbia University Asthma Coalition aims to improve asthma care among high-risk populations through a three-pronged approach. Researchers will implement culturally appropriate programs, increase public awareness, and form partnerships with primary care providers to ensure implementation of National Asthma Education and Prevention ...
Researchers discovered a direct link between apoE and cerebral amyloid angiopathy (CAA), a leading cause of bleeding strokes in the elderly. Decreasing apoE expression may inhibit CAA buildup, lowering the risk for cerebral hemorrhage.
Crystals grown in space may produce better semiconductor materials due to reduced gravity effects. The 'detached growth' process, performed on the space shuttle, has produced pencil-thin crystals with uniform distributions.
Research reveals that individuals coping with HIV/AIDS exhibit diverse information-seeking behaviors, from avoiding information to seeking out multiple sources. Understanding these complexities is crucial in developing effective treatment programs, as uncertainty can be a natural part of life for some individuals.
A new study predicts that anal Pap smear screening every two to three years would detect pre-cancerous lesions among high-risk HIV-negative men and allow for early treatment of anal cancer. The analysis suggests that this simple procedure could save lives at a cost comparable to annual mammography.
Researchers have made the first direct observations of magnetic reconnection, a switch that allows energy to be transferred between solar wind and Earth. The phenomenon is responsible for aurora borealis, aurora australis, and occasional radio and satellite disruptions.
Researchers propose a 10-year effort to understand Arabidopsis genes and their interactions. The goal is to build a complete "wiring diagram" of the plant's biological pathways and create a 'clickable plant' for interactive exploration.
A collaborative study found that media coverage of new medications tends to exaggerate their benefits, ignore their risks, and fail to disclose their costs. Only 40% of news stories citing experts with financial ties to the drug being studied disclosed this potential conflict of interest.
The FDA has approved a new cancer treatment using microscopic glass beads that deliver localized radiation to liver tumors. The treatment involves injecting radioactive glass beads into the liver, where they kill malignant cells with minimal side effects.
