Climate change is expected to lead to a major ecological upheaval in Antarctica as predatory king crabs potentially invade the continental shelf. The invasion could disrupt the primeval marine communities that have lived there for millions of years, leading to a loss of unique biodiversity.
Researchers at Moffitt Cancer Center have identified PHF20 as a novel transcriptional factor that regulates gene P53, a crucial gene for normal cell growth and tumor suppression. The study found that PHF20 directly interacts with p53 and stabilizes it, allowing for its activation in response to DNA damage.
Researchers at the University of Liverpool have developed novel compounds targeting the glycine receptor to treat chronic pain without sedative effects. The project aims to create a safe and effective oral tablet, addressing a huge unmet medical need for 20% of adults in Europe and the US.
Researchers used Active Shape Model to simulate fluid forces acting on breast cancer cells in blood flow. The study aims to develop new therapies targeting metastasis by understanding mechanical properties of cancer cells.
A new silicone model makes it possible for researchers to intuitively understand protein structures, positions, and interactions. The model allows users to test ideas about molecular interactions and simulate docking maneuvers, which can lead to innovation in drug design.
Researchers create super-sensor using nanoscale gold spheres to detect single samples of the smallest known viruses. The sensor uses 'whispering gallery mode' to measure precise frequency changes, allowing for accurate detection and sizing of viruses.
Heavy rainfall observed by NASA's TRMM satellite over Tropical Storm Isaac poses significant risks to the eastern Caribbean, particularly Hispaniola and Cuba. The storm is expected to bring extreme rainfall totals of 8-12 inches, with isolated amounts reaching up to 20 inches.
Research from the University of East Anglia shows that nearly half of UK private water supplies are contaminated, putting under-10s at almost five times higher risk of stomach infections. Children in these households suffer around five bouts of sickness or diarrhoea per year, a rate similar to developing countries.
The study reveals that inhibitory Smads bind directly to their targets without requiring phosphorylation, constituting a crucial step in the regulation of gene transcription. This discovery sheds light on how organisms achieve balance between TGF-beta signaling pathways, critical for maintaining tissue and organism health.
A study by Adrian Bejan suggests that larger bodies tend to have longer lifespans and greater distances traveled. This applies to both animate and inanimate systems, with rivers, jets of air, and vehicles following a similar pattern.
Tropical Storm Tembin made a quick track across southern Taiwan before re-emerging over the open waters of the Philippine Sea. The storm has strengthened and expanded since crossing the island, with tropical-storm-force winds extending out 170 miles from its center.
A recent study found that Mexican-Americans with an ancestral link to Amerindian tribes have higher insulin resistance levels, a key indicator of several chronic conditions. The research suggests that ethnicity information is crucial in identifying individuals at high risk of disease, and that genetic markers can be used for personaliz...
Researchers at the University of Gothenburg discovered how astrocytes control the formation of new neurons in the brain. By secreting specific molecules and cell-cell interactions, astrocytes regulate the birth rate of new neurons and their integration into existing neuronal networks.
Researchers discovered that pollutant particles accumulate in specific areas of the urban environment, forming coherent structures. This finding can help generate maps to identify high-pollution zones and inform strategies for mitigating pollution.
Researchers have developed a digital microscope that creates high-resolution images at fast speeds, enabling scientists to study biological processes like cell activity in greater detail. The new device uses a programmable micromirror system to reject unwanted light and improve image quality.
A study published in The Veterinary Journal found that horse branding is unreliable for identification due to poor legibility and tissue damage. Researchers examined brand marks on over 250 horses and found that only a small percentage could be clearly read.
Researchers at Cedars-Sinai Medical Center found that multifocal glioblastoma patients have significantly shorter overall survival compared to those with single tumors, even when treated with the same therapies. Median overall survival for multifocal patients was six months, while single-tumor patients survived 11 months.
A recent survey conducted by IPAC-CO2 Research Inc. found that only 2% of Canadians reject the concept of climate change, while most believe it is real and caused by human activity. The survey also revealed divisions in opinions on how to address climate change, with some prioritizing cleaner cars and others supporting a carbon tax.
Physicists from the University of Southampton used Diamond Light Source's new I10 Beamline to search for 'hidden magnetic states' in exchange-spring magnets. They have identified at least three different classes of these states, which could provide important confirmation of a theoretical model.
Researchers at University of Minnesota develop new non-invasive brain scan technique to study seizures immediately after they occur. The method could lead to breakthroughs in identifying the brain regions responsible for seizures and finding effective treatments.
The US Department of Homeland Security is conducting a series of tests in the Boston subway system to measure the real-world performance of new sensors designed to detect biological agents. The sensors, developed by several companies, are expected to identify and confirm the release of biological agents within minutes.
Engineers at Oregon State University have developed a method to use microwave heating to synthesize copper zinc tin sulfide, a promising solar cell compound. This approach saves money, works well, and can be scaled up easily compared to traditional methods.
A study reveals that theatre demand is driven by different classes, with the working class favoring comedy and the intellectual class preferring drama. The results show that wealthier individuals are influenced by reviews, while those in the middle class opt for classic theatres.
The National Association of Science Writers has awarded $2,500 to investigative journalists who reported on the impact of science on society. The winners include authors of books like 'Panic Virus' that shed light on vaccine controversies and environmental issues.
A Kaiser Permanente study found that obese children and adolescents are twice as likely to have gallstone disease compared to those with a normal body mass index. Hispanic youth are more likely to develop gallstones than youth of other races and ethnicities.
Glenn Hicks led a groundbreaking workshop in Dhaka, introducing modern approaches to biotechnology research. He found Bangladeshi students were eager to learn but needed practical training, highlighting the importance of education for quality of life.
Research found that desert-like, or xeric, yards have a more even bird community and superior habitat compared to moist, or mesic, grass lawns. Native plants in urban yards offer birds 'mini-refuges' and help offset losses of biodiversity in cities.
