Brent Heeringa's research focuses on three specific problems: optimal algorithms for hierarchical data, dynamic models of information organization, and new models for categorical data. His project aims to create systems where desired information is quick and easy to find.
The NRL's P-3 aircraft and Air Force Reserve WC-130J conducted meteorological research on tropical cyclones in the Western Pacific from August to September. The project aims to increase predictability of tropical cyclones and gather data to validate satellite-based techniques for intensity estimation.
The Engineering and Physical Sciences Research Council (EPSRC) has announced a £250 million initiative to create 44 training centers across the UK, generating over 2000 PhD students. These centres will focus on tackling pressing issues like climate change, energy, and high-tech crime.
A comprehensive analysis by CIFOR offers options to address forest destruction and degradation's role in global greenhouse gas emissions. The report suggests integrating REDD with tighter emissions targets for a more ambitious climate strategy.
UC Davis researchers are exploring a new gene therapy approach to cure AIDS by replacing HIV-infected immune cells with HIV-resistant ones. They plan to conduct safety and efficacy trials using a mouse model before moving on to human clinical trials.
Jeannie Albrecht is heading one of 29 academic/industrial research teams working on prototypes to expand the security, manageability, and versatility of networking systems. The team aims to build a user-friendly experiment control and management framework called Gush to support large-scale network management.
The Linheng Li Lab has identified the precise location of the bone marrow stem cell niche, building on previous discoveries. The findings reveal a special zone that includes both osteoblastic and endothelial components, which maintains HSCs in their resting state and promotes expansion in response to stressors.
Scientists have discovered that transporting juvenile salmon downstream can hinder their ability to migrate back to their breeding grounds as adults. The study found that transported juveniles had lower survivorship and were less likely to find their way home, due to being disoriented by the boat journey. This can reduce the genetic fi...
The Stowers Institute's Workman Lab has made a groundbreaking discovery of a novel histone demethylase protein complex, which plays a crucial role in regulating transcription elongation. The research reveals that this protein complex associates with the heterochromatin protein 1a and stimulates its histone demethylation activity.
Frank Morgan has received a three-year NSF grant to research manifolds with density, a generalization of Riemannian manifolds. This work builds on previous summer research and aims to solve isoperimetric problems in probability theory and geometry.
The Obesity Institute at Children's National Medical Center gathered experts to discuss translational, clinical and community research successes in childhood obesity prevention and treatment. Key findings include successful community interventions for inner-city youth, emerging genomic research on high LDLs and type 2 diabetes risk.
A recent study found that patients with idiopathic pulmonary fibrosis are three times more likely to experience severe coronary events, including heart attacks. The disease is also linked to increased risks of angina, stroke, and deep vein thrombosis.
Research finds that progressive lung damage in CF patients can begin as early as infancy, even if lung function is normal shortly after diagnosis. Early intervention in the first six months of life may be key to slowing disease progression.
Researchers developed a transgenic mouse model expressing mutant prion protein, resulting in a fatal neurological disorder. The discovery may help unravel the mystery of this progressive disease affecting humans and animals.
The Baumann Lab discovered an important step in the maturation pathway of telomerase, an enzyme that replenishes chromosome ends with every cell division. This finding sheds light on human health and demonstrates that interfering with telomerase maturation can inactivate telomerase.
The University of Texas M. D. Anderson Cancer Center is hosting its first international conference on inflammatory breast cancer to bring together clinicians and scientists to share new clinical discoveries and educational workshops. The conference aims to improve diagnosis and management of this rare but deadly disease through joint i...
A team of scientists at the University of Granada has developed a new optical technique that can distinguish between original and bootleg CDs. This method uses light diffraction on the CD surface to identify differences between industrial processes and homemade copies, allowing for the detection of bootleg CDs.
Women exposed to secondhand smoke as adults or children are more likely to face fertility problems and suffer miscarriages, with a 68% increased chance of difficulty getting pregnant. The study analyzed data from over 4,800 non-smoking women and found that four out of five reported exposure to secondhand smoke during their lifetime.
A team of geologists analyzed a cave stalagmite and found that the Eastern Mediterranean became drier between 100 A.D. and 700 A.D., coinciding with the fall of Roman and Byzantine rule in the region. The high-resolution climate record shows sharp drops in precipitation around 100 A.D. and 400 A.D., which may have weakened these empires.
Researchers at Berkeley Lab have created ceramics that mimic mother of pearl, outperforming human-synthesized composites by 300 times in terms of toughness. The materials use a combination of alumina and polymer to dissipate strain energy and achieve remarkable strength and resistance to fracture.
A new study reveals that the brain's nerve cells can survive with damaged connections for several months before deteriorating further. The research suggests a time window in which damaged connections between brain cells could recover under the right conditions, potentially halting symptoms and allowing functional recovery.
The AAAS/Subaru SB&F Prize for Excellence in Science Books promotes science literacy among young readers. The prize recognizes 19 finalists in four categories, including children's picture books, middle grades science books, young adult science books, and hands-on activity books. Winners will receive $1,500 and a plaque.
Researchers at Massachusetts General Hospital found a subpopulation of hematopoietic stem cells that reproduce much more slowly than expected. This discovery may lead to improved treatment outcomes for leukemia and other marrow-based diseases through enhanced bone marrow repopulation.
A new study found that a fractional dose of a commonly used meningitis vaccine is as effective as the full dose, allowing for more efficient use of scarce vaccine resources. The research was conducted in Uganda and suggests that using 1/5 doses could be an alternative in mass vaccination campaigns during epidemics.
