Researchers used a powerful computing cluster to simulate moon motions over 1 billion years, discovering that the sun's gravity pulls smaller moons from their orbits. The study reveals how giant planets capture and shape the orbits of tiny moons, shedding light on Jupiter's unusual satellite system.
Research reveals Amazon forest fragments are more susceptible to extinction due to overhunting, increased airborne pollutants, and heightened fire risks. Climate change may further exacerbate these effects, threatening biodiversity in fragmented landscapes.
Researchers have found a new, hidden piece of the influenza virus that may kill immune system cells. This protein was discovered by accident while studying
UT Southwestern Medical Center has been awarded $3.6 million in funding to support 19 research projects across various disciplines. The largest grant will go towards developing a cancer-detecting blood test, which has already shown promising results in clinical trials.
A study by Professor Melissa DelBello found that quetiapine added to divalproex reduced psychotic symptoms in significantly more patients than divalproex alone. The quetiapine combination group also showed improved outcomes without treatment-emergent extrapyramidal symptoms.
Researchers at Thomas Jefferson University developed a computer model showing that familial adenomatous polyposis (FAP) may begin when adult stem cells in the colon go out of control. The model suggests that an increase in stem cells triggers colon cancer, indicating that cancer may be a stem cell disorder.
Researchers at Northwestern University have developed a method to create triangular nanoprisms in large quantities, which can be used as new diagnostic labels for detecting biological weapons and diseases. The nanoparticles' unique optical properties make them a promising building block for detection science.
Researchers found that repeatedly exposing people to positive images of stigmatized groups, such as African Americans and the elderly, can alter their nonconscious attitudes towards those groups. This strategy may help reduce prejudices and improve social welfare.
Carl Picconatto, a chemist from Wisconsin, has been named a congressional fellow by the American Chemical Society to work in Rep. Connie Morella's office on science and technology issues. He previously interned at the National Academy of Sciences and holds degrees from Columbia University and the University of Notre Dame.
A team of scientists has successfully guided human embryonic stem cells to become precursor brain cells in a laboratory dish. Transplanted into baby mice, these cells further differentiated into neurons and astrocytes, paving the way for potential treatments of Parkinson's disease and spinal cord injuries.
Research found giant pandas have moderate genetic diversity compared to other carnivores, with some populations showing signs of isolation. To ensure the species' survival, conservation efforts focus on restoring gene flow among populations through natural corridors and ecological restoration.
Researchers investigated the influence of gender on upper airway structure and function, finding no gender differences in resistance and Pcrit. These findings contradict previous assumptions and suggest a possible explanation for the male predominance of OSA, potentially related to neurochemical control or other factors.
A new study suggests that smaller hospitals can perform heart bypass surgeries with similar outcomes to high-volume hospitals for low-risk patients. Moderate- and high-risk patients, however, should still seek major medical centers with high-bypass volumes to minimize mortality risk.
USGS scientists Jon Keeley and C.J. Fotheringham argue that natural fire regimes in chaparral ecosystems are not characterized by frequent small fires, but rather by landscape-scale crown fires. They suggest that limited, strategically placed burns are more cost-effective than large-scale prescription burning.
A study by UCSF found that cancer patients often prefer to experience pain over the side effects of opioid analgesics. Effective pain management requires repeated assessment and adjustments in dosage, according to experts.
Researchers discover widespread hybridization between introduced rusty crayfish and native species, altering ecosystems and leading to population displacement. The study highlights the significant impact of non-native species invasions on biodiversity.
Researchers question the efficacy of prescribed burning in reducing large, intense forest fires. They argue that this technique is not suitable for closed-canopy forests and shrublands where natural fires are more frequent and severe. This approach can also have negative ecological consequences.
Richard Sachleben, a Massachusetts chemist, has been named a congressional fellow by the American Chemical Society. He will work on energy technology and infrastructure safety issues for the Energy Subcommittee of the U.S. House of Representatives Committee on Science.
A NASA review highlights known and potential gender differences in physiological responses to spaceflight, including cardiovascular and exercise physiology, barophysiology, and pharmacotherapeutics. The review also addresses reproductive issues such as menstrual function and endometriosis in space.
Researchers at UC Berkeley and Stanford University discovered how lobsters sniff their way around a watery world by flicking antennules into contact with chemosensory hairs sensitive to chemicals. This motion captures detailed maps of swirling odors, suggesting that small differences in odor concentration are preserved.
