The study confirms the protective brain hypothesis, suggesting that large-brained mammals live longer and reproduce more times due to enhanced survival. The analysis of 493 species reveals a link between brain size and longevity, with larger brains associated with greater survival rates.
A new study challenges the long-held critical depth hypothesis, which suggests that phytoplankton bloom in temperate oceans due to improving light conditions. Instead, researchers found that winter storms play a key role in creating blooms, and warmer ocean temperatures may actually curtail productivity.
Agricultural Research Service chemist Thomas Wang found that resveratrol, a bioactive compound in grapes and plant foods, can inhibit cancer cell growth but also increase tumor vessel development with prolonged exposure. The study suggests that diet complexity and gene expression are key layers in cancer development.
Chemists from NYU and Russia's St. Petersburg State University have created crystals with a twisting mechanism that reverses when they thicken, creating needles with colorful helical structures.
The Low-Cost Imaging Terminal Seeker (LCITS) technology can swiftly engage and defeat multiaxis attacks by small swarming boats, increasing the number of targets that can be engaged in a short amount of time. LCITS successfully concluded its program, paving the way for its transition to the fleet.
Researchers at Rockefeller University have identified two compounds emitted by mosquito predators that deter female mosquitoes from laying eggs in pools of water. These natural insect repellents could provide an environmentally friendly alternative to controlling disease-carrying insects.
Mice cages alter brains in mice used in laboratories, affecting outcomes of research, according to a breakthrough study published in PLoS One. The type of cage can change the brain's olfactory bulb and levels of aggression.
The adoption of digital patient records, increased regulation, and provider consolidation highlight the need for better information security in healthcare. Patient concerns about sharing medical information online are common, with a recent survey showing three-quarters of patients worried about health websites breaching their privacy.
Researchers at Florida Institute of Technology have developed a streamlined process for synthesizing the chemical compound CDNI-Glu, reducing production time from 150 hours to 24 hours. The licensed technology will be commercially available through Tocris, enabling neuroscientists to study brain neural networks more efficiently.
Scientists at NIH identify novel Staphylococcus aureus toxin LukGH, which destroys human immune cells and increases MRSA severity. The toxin is secreted into the environment, forming pores in neutrophils that lead to their destruction.
Researchers identify silencing genes in malignant plasma cells that can be targeted by inhibitors of the Polycomb repressor complex. This approach may lead to new strategies for treating multiple myeloma.
Tropical Depression 6E has been downgraded to a remnant low pressure system in the Eastern Pacific Ocean. It's now being stretched by strong vertical wind shear and moving into cooler waters, making strengthening back into a tropical storm unlikely.
Astronomers have discovered the first case of a distant galaxy being magnified by a quasar, allowing them to measure the masses of these host galaxies. This breakthrough provides new insights into galaxy formation and evolution, enabling scientists to better understand the relationship between quasars and their host galaxies.
Seemingly redundant portions of the fruit fly genome contribute to normal development by ensuring genes are turned on and off at the appropriate times. The discovery sheds light on the potential importance of 'junk DNA' in understanding developmental disorders.
The new ARC Center of Excellence in Plant Cell Wall Biology will enhance biotechnologies for crop industries, associated food industries, and renewable transport fuels. The center will be led by the University of Adelaide and involves collaboration with international partners to develop new technologies and processes.
The International AIDS Society (IAS) has announced the winners of four prestigious scientific awards, recognizing innovative HIV and AIDS research. The Women, Girls and HIV Investigator Prize was awarded to Naina Rani for her work on mainstreaming the Prevention of Parent to Child Transmission program in India.
A novel microfluidic HIV test developed by Prof. Alexander Revzin uses antibodies to 'capture' white blood cells called T cells affected by HIV. The test detects the types and levels of inflammatory proteins released by the cells, providing six parameters simultaneously from a small blood sample.
NOAA has selected Scripps Institution of Oceanography, UC San Diego, to lead a new research partnership, CIMEC, to study climate change and coastal ecosystems. The institute will focus on ecosystem-based management of fisheries and continue the longstanding work of JIMO in climate and ocean sciences.
Agnieszka Bialek wins Royal Photographic Society's Selwyn Award for her work on multi-spectral imaging, which reveals details unseen by the eye. Her IRIS technology captures eight replicated images of an object at different wavelengths, enabling characterisation of materials with variations in colour or appearance.
Research finds key gene expression pathways involved in Candidiasis-associated denture stomatitis, with significant up-regulation of TLR2 and CD28 signaling. Saliva analysis reveals six extracellular protein genes linked to stomatitis.
