Scientists study seismic waves to understand tectonic plate dynamics, aiming to resolve the long-standing 'great plate debate'. They use data from seismometers worldwide to characterize wave origins and time delays, creating a X-ray image of the planet's internal structure.
Researchers have identified a brain region involved in planning movement, which also controls gain control of eye movements. This finding provides new insight into how the brain adjusts to moving objects, allowing for smooth image display.
Familial Dysautonomia, a devastating disorder, has been linked to mutations in the IKBKAP gene. The gene's disruption leads to poor development and degeneration of sensory and autonomic nervous systems, resulting in symptoms such as abnormal sweating and insensitivity to pain.
A University of Michigan study finds that ancient human fossils from Australia and Europe show distinctive characteristics to an older African population, contradicting the 'Eve theory'. The research suggests that multiple groups of humans survived and thrived globally, rather than a single ancestral group replacing others.
Researchers at WashU Medicine discovered that Gram-positive bacteria like Streptococcus and Staphylococcus use cholesterol-dependent cytolysins to inject toxins into host cells, paving the way for entry of other proteins. This finding could lead to new approaches in treating antibiotic-resistant infections.
Researchers have discovered a gene that makes mousepox virus deadly to lab mice, raising concerns about its potential misuse in biowarfare. The technique could be used to strengthen biological weapons based on viruses affecting humans.
Astronomers studied 37 nearby galaxies using Hubble Space Telescope images in ultraviolet light, finding that faraway galaxies may not be inherently odd-shaped. The survey suggests that astronomers are detecting the 'tip of the iceberg' of very distant galaxies, and that their shapes may be influenced by incomplete observations.
Researchers have successfully introduced a new gene into the unfertilized eggs of rhesus monkeys, resulting in several pregnancies and live births. The breakthrough technology has the potential to develop animal models of diseases with greater resemblance to human conditions.
Researchers have discovered a 4.4-billion-year-old zircon crystal that suggests the early Earth had a low-temperature environment with water and conditions suitable for life. The findings contradict conventional wisdom, which predicted a magma ocean, and may indicate the Earth cooled faster than thought.
Children's adjustment problems after divorce depend on their temperament and mother's parenting style, according to a study. Impulsive children at risk of depression if mothers are inconsistent with rules and discipline.
Researchers design 5-Helix protein to block HIV entry into human cells, offering a promising alternative to current treatments. The protein has potential applications as a broad-spectrum inhibitor against various viruses and could serve as a model for generating antibodies against HIV.
The discovery confirms the existence of an event horizon around the massive black hole Cygnus XR-1. The data shows chaotic fluctuations in ultraviolet light from swirling gas, consistent with theories of what scientists predict to see when matter falls close to the event horizon.
Researchers found that gene Rb2 inhibits angiogenesis, a critical process for tumor growth. The study suggests that Rb2 may be used to treat lung cancer and glioblastoma by blocking blood vessel formation.
The Idaho National Laboratory's Rapid Solidification Process (RSP) Tooling has been recognized by the Department of Energy for its innovative approach to fabricating precision tooling. This process enables mass-produced items to be created more quickly and cheaply, reducing production costs and turn-around time.
The Idaho National Laboratory's lithium battery solid electrolyte has been recognized by the DOE as a top consumer product, offering substantial savings and improvements in safety. The technology promises longer-lasting rechargeable batteries with reduced waste, making it suitable for applications such as space exploration and pacemakers.
Researchers at Johns Hopkins Children's Center found a faulty releasing hormone receptor gene in three families with isolated growth hormone deficiency type 1-B, the most common type of growth hormone-deficient dwarfism. The study suggests that this condition is not caused by a defect in human growth hormone production.
A new computer recycling model developed by Purdue University's Julie Ann Stuart can help recyclers determine the economic viability of processing bulk materials. The model takes into account factors such as metal prices and helps prevent financial losses for recyclers.
