The research suggests sex differences may have fueled the evolution of diverse fauna, highlighting the importance of considering both sexes.
Research reveals that rare genetic variants in fruit flies can provide a survival advantage, with individuals with unique traits being less conspicuous to predators. The study's findings offer insights into why genetic variation persists in nature and may have implications for understanding human food-related disorders.
Researchers have discovered critical regions within prions that determine much of their behavior, providing a new framework for exploring prion biology. These regions, known as recognition elements, can be activated by environmental conditions and amino acid sequence alterations.
Researchers found that FDG-PET imaging can identify patients who respond to chemotherapy, allowing for early termination of futile treatment. This improves patient care by providing an alternative approach, such as stopping chemotherapy or switching to a more adequate therapeutic option.
Researchers at the University of Missouri-Columbia are studying the effects of silver nanoparticles on wastewater treatment systems. The study aims to determine how these particles interact with bacteria used for water purification and assess their potential environmental impact.
Researchers at the University of Manchester used a laser scanning system to create a detailed 3D model of dinosaur tracks in Spain. The portable RIEGL LMS Z420i scanner allowed for rapid and high-resolution mapping of the fragile site, preserving important information on dinosaur locomotion.
A recent study published in The Lancet found that Swedish snus is associated with a higher risk of pancreatic cancer, despite being less harmful than smoking. However, switching from cigarettes to snus can potentially lead to significant health benefits for smokers.
St. Jude researchers used a new technique to monitor the movement of DNA repair proteins as they interacted with each other and gathered at the site of damage. The study found that disruption of these proteins can cause mutations, cell death, or cancer, providing critical insights into DNA repair mechanisms.
Researchers have identified a specific class of small peptide elicitors that help plants react to insect attack, triggering defensive chemistry and improving protection against pests. The discovery opens the door for genetic manipulation of plants with improved defense mechanisms.
Scientists on NASA's Mars Exploration Rover mission found evidence of long-past explosive volcanic activity at Home Plate, a plateau in Gusev Crater. The data collected by the rover supports earlier findings that water once existed at or beneath the planet's surface.
The opossum genome sequence has provided significant insights into the evolution of the mammalian immune system, revealing similarities with human immune-related genes. The sequence also revealed ancient DNA elements that have been recruited for specific biological activities, such as regulating gene expression.
A study found that parents typically focus on negative aspects of sex, while peers promote positive messages. Parents are strongest supporters of abstinence and provide information on pregnancy and fertilization, but fail to discuss other topics. Peers encourage non-relational sex and promote sexual freedom, while the media reinforces ...
The first marsupial genome sequence has been published, providing new insights into human evolution and the origins of the human genome. The study found that most genetic innovations leading to the human genome sequence lie in areas referred to as 'junk' DNA, highlighting the importance of non-gene regions in shaping mammalian genomes.
A new NASA study suggests that greenhouse-gas warming may raise average summer temperatures in the eastern United States nearly 10 degrees Fahrenheit by the 2080s. This could lead to extremely hot summertime temperatures, especially during summers with less-than-average frequent rainfall.
A study published in the Journal of Physiology found that adding marine omega-3 fatty acids to a steer's diet increased sensitivity to insulin, improving protein metabolism. This could lead to alternative methods for increasing muscle mass in animal farming.
Sholl's research uses metal hydrides like alanates and borohydrides to create lightweight, low-cost storage materials. This could improve the efficiency of hydrogen cars and reduce pollution.
A recent study has found that children with amblyopia, also known as 'lazy eye,' exhibit poorer fine motor skills and lower perception of social acceptance. The research, led by Ann Louise Webber, used standardized tests to measure the children's motor skills and self-esteem. The results indicate that treating a child's eye condition m...
