The Pacific Northwest National Laboratory is conducting a marathon testing regime to ensure personal radiation detection equipment meets new standards for identifying potential threats. The tests will evaluate the electrical systems, mechanical operations, environmental susceptibilities, and radiological sensitivities of over 100 instr...
Researchers identified two genetic signatures in CLL samples, one associated with a good prognosis and the other with a mutation in the Ig gene. The study suggests that miRNA expression may be used to predict CLL behavior and provides new targets for future drug development.
A new UCSD study found that general pediatricians and specialists frequently miss diagnosing Kawasaki disease in children under six months and over eight years old, leading to preventable coronary artery damage. The study aims to raise awareness and provide recommendations to improve diagnosis and treatment of the disease.
Recent findings by scientists at Lawrence Berkeley National Laboratory and University of California, San Francisco, reveal telomere crisis as a key event in breast cancer progression. The researchers found that telomere length decreases in hyperplasia, carcinoma in situ, and invasive cancers, indicating increased genomic instability.
A phase 1 vaccine trial has demonstrated that a group A streptococcal vaccine appears safe and well-tolerated, inducing immune responses capable of conferring protection against multiple strains. The study's findings suggest that a specific dose and schedule may be effective in preventing group A streptococcal infections.
Despite searching for large lakes and seas, no conclusive evidence of water has been found. However, the Spirit rover did uncover small amounts of water in rock samples. The team also took spectacular photographs of Martian landscapes, including 3-D images that provided valuable insights.
A new study found that children walk almost as much as their grandparents did in the 1940s, with over 75% of 17/18-year-old trips taking place on foot. The researchers suggest transport policy should prioritize pedestrians' needs.
The American Physiological Society has awarded over $36,000 to its 2004 undergraduate research fellows. The fellowships cover travel and living expenses during a 10-week fellowship program.
A new study found that three mahogany species require specialized soils with specific plant nutrients, limiting their distribution. The research has significant implications for forest management and 'green' certified timber.
Researchers found that monkeys with impaired dopamine receptors were more productive and accurate in their tasks, while those without the receptors procrastinated. The study uses a gene knockdown technique to deplete D2 receptors, leading to improved performance.
Research reveals that women in IT jobs face complex interactions of factors including social networks, age, parenthood, and education level. Managers can address the issue by creating diverse networking opportunities and helping employees develop their own skills.
Researchers analyze daily temperature ranges to explain global warming trends. A new seismic model reveals the cause of New Zealand's volcanism by tracking magma movement. Small robotic aircraft can now patrol the ocean, providing high-resolution oceanographic observations.
Researchers at the University of Warwick analyzed French trade cards to understand consumer habits, social values, and advertising techniques during the 18th century. The study revealed how trade cards seduced people into buying goods by showing beautiful displays and suggesting exclusivity.
Researchers at the University of Nevada, Reno recorded a cluster of nearly 1,600 small earthquakes beneath Lake Tahoe, causing the nearby Slide Mountain to rise by 8 millimeters. The earthquakes coincided with an unprecedented uplift of the mountain, which scientists believe was caused by magma movement about 20 miles deep.
A new study has found that high levels of thyroid hormone are linked to an increased risk of miscarriage in women who are resistant to normal levels. The research, conducted on a family with a rare genetic disorder, revealed a significant increase in miscarriage rates among affected mothers compared to unaffected relatives.
A recent study published in JAMA found that excessive maternal thyroid hormone levels can lead to miscarriage and negatively impact fetal growth, with unaffected fetuses being more susceptible to these effects. The study also discovered that high maternal thyroid hormone levels can induce a catabolic state during fetal life.
Researchers found genetic changes in mice fed a low-calorie diet that suppressed diseases and protected against chemical exposure. Compounds mimicking these changes target key receptors, including PPARalpha, with potential for developing life-extending drugs.
Excess nitrogen and phosphorus from farming activities cause eutrophication, creating a food web that imperils frogs. A parasite, Ribeiroia ondatrae, infects tadpoles, causing deformities.
A study found that vaccinated cases were half as contagious as unvaccinated cases, with varying levels of contagiousness depending on the number of lesions. The authors suggest continued monitoring to improve vaccine policy decisions for future generations.
A recent study analyzing 100,000 students preparing for the SAT, ACT, and GRE reveals poor study habits among high schoolers. The study found that students spent more time on the test preparation website than expected, with many not practicing math or reading comprehension questions.
A team of researchers has developed an implantable electronic device that can help doctors monitor heart rhythms and prevent atrial fibrillation (AF) attacks. The device uses lower energy shocks to terminate AF episodes, reducing pain and risk of complications.
