Researchers at the University of Nottingham have identified a key gene, Smed-prep, essential for regenerating a planarian worm's head and brain after amputation. This discovery could one day lead to understanding human organ regeneration and tissue repair.
Cristina Eisenberg's new book highlights the importance of top predators in maintaining healthy ecosystems. Research shows that keystone predators like wolves, cougars, and bears play a critical role in controlling population growth and preventing overgrazing.
A long-term follow-up study of extremely preterm children reveals nearly a quarter had a psychiatric disorder by age 11. The study highlights the need for early cognitive and psychological monitoring to identify emerging neuropsychiatric disorders.
Scientists developed a new computational model to identify targets of regulator genes in the human genome. The method combines biochemical and probabilistic modeling to uncover physical models of cell regulation, offering promise for improving understanding of biological systems.
The McGill University researchers will be working on various projects, including cancer research and bone degeneration, using the new funding. The Canada Foundation for Innovation's investment will help develop Canada's global reputation as a place where outstanding research and training is being conducted.
Molecular biologist Alan Ashworth will receive a $50,000 grant from the Samuel Waxman Cancer Research Foundation to study PARP inhibitors in BRCA-mutated cancers. His research aims to develop novel treatments for triple-negative breast cancer and other related cancers.
Researchers at Johns Hopkins Medicine have identified a protein in sensory cells of fruit flies that allows them to detect and avoid noxious chemicals. The discovery opens up new possibilities for controlling insect pests and protecting crops.
The International Barcode of Life (iBOL) project has received a significant funding boost, totaling $80 million from Canadian agencies. The new funding will support the expansion of DNA barcode data and informatics platforms to facilitate species identification and discovery.
A retrospective study found that complete revascularization significantly improved outcomes for patients with coronary artery disease (CAD), with a 3-year mortality rate of 6.6% compared to 14.8% in those with incomplete revascularization. The study also revealed that advanced medical therapy may contribute to improved mortality rates.
Researchers warn that biometric logins may not be secure on the go due to mobile device limitations. Biometric technology uses fingerprints, voice recognition, or typing patterns for authentication.
USDA ARS scientists collaborated with NRC experts to model radioactive material movement in the vadose zone. They found that gaps in fine-material layers significantly affect tracer transport in soils and shallow groundwater.
Researchers present novel approaches to identify and treat congenital cardiovascular defects, which can lead to heart failure. Studies focus on molecular mechanisms and imaging techniques to diagnose and follow patients.
Researchers found that volunteers high in neuroticism traits had lower volumes of gray matter in the frontal and medial temporal brain regions compared to those high in conscientious traits. This association suggests that personality may influence the rate of brain aging.
Researchers investigate seismic activity in the Midwest US, shedding light on causes of intraplate earthquakes. The study reveals insights into stress within fault zones and the impact of glacial rebound on earthquake frequency. Key findings also highlight correlations between mantle density structures and topographic uplift.
Cyclone 24S was renamed Tropical Storm Sean as it matured, going through two numbered nicknames before receiving its human name. It showed strong thunderstorms with cloud tops as cold as -63°F, and forecasters predict further intensification over the next 12-24 hours.
Iain Buxton, a pharmacology professor at University of Nevada School of Medicine, received a share of $2.6 million in grants to study genetic variants contributing to preterm birth. His study aims to predict and prevent preterm births by identifying alterations in a specific gene.
A study published in Medical Decision Making predicts that adult US obesity rates will remain stable over the next 10 years. However, certain groups such as black young adults, children aged 6-9, and black children are projected to experience rising overweight rates.
The Lancet China special issue was launched at a joint event in Beijing, combining the inauguration of the China Center for Health Development Studies. The issue features various articles on healthcare reform, children's health, air and water quality, and more.
Researchers at Berkeley Lab have created micro-supercapacitors with high energy storage densities, potentially replacing batteries in portable devices. The new technology integrates supercapacitors into microfabrication processes, enabling faster and longer-lasting energy storage.
A study on trembling aspen found that phenolic glycosides and extrafloral nectaries are distributed together in the same leaves, contradicting previous assumptions. The presence of extrafloral nectaries is positively correlated with higher levels of chemical defenses, suggesting a complex relationship between these defense mechanisms.
Researchers at St. Jude Children's Research Hospital found that individuals who received the 1976 vaccine mounted a stronger immune response against both the 2009 pandemic H1N1 virus and a different H1N1 strain. The study suggests that routine vaccination against seasonal flu might confer broader-than-realized protection.
A new study reveals that even slight reductions in PTEN expression can significantly increase cancer susceptibility in specific tissues, implying that environmental factors like diet and carcinogens may drive tumor development. This finding has implications for the development of diagnostic tests targeted to these gene alterations.
Researchers found that men with multiple affected relatives have a substantially increased risk of developing prostate cancer. The study suggests that doctors should urgently recommend early detection screenings for men with several affected relatives, particularly if they have been diagnosed at a young age.
Researchers are developing a new chemical enhanced oil recovery technology to access the remaining oil in existing US reservoirs. The project aims to increase domestic oil production from marginal wells, reducing reliance on deepwater drilling.
