A new field of ecology explores how humans influence urban ecosystems, raising questions about accountability and stewardship. Cities are increasingly recognized as significant ecological systems with diverse conditions, energy-intensive operations, and a substantial ecological footprint.
The study will analyze marine life around eight oil platforms in the Santa Barbara channel, focusing on species with desired natural products. The research aims to determine the distribution, abundance, and genetic similarities of these organisms, as well as their potential for harvesting sustainably.
Scientists have found that the tropical Pacific Ocean played a key role in driving past ice ages, cooling by at least 3 degrees Celsius during each of the last five ice ages. This discovery challenges the long-held theory that high latitude and North Atlantic processes were the primary drivers of climate change.
Researchers observed a bright X-ray flare from a brown dwarf, LP 944-20, which lasted nearly two hours and had an energy comparable to small solar flares. The flare's origin is believed to be in twisted magnetic fields beneath the surface of the brown dwarf, providing strong hints about the existence of turbulent magnetized hot material.
Researchers analyze three whale species to assess their recovery status and develop novel approaches to understanding decline. The study highlights the difficulties in determining when a population has recovered, emphasizing the need for data-driven conservation policy.
The Fender's blue butterfly requires specific nectar and host plants to complete its reproductive cycle. A new study by University of California, Santa Barbara researcher Cheryl B. Schultz found that the species needs approximately 20 milligrams of wild flower nectar per square meter to support its population.
Researchers at the University of California, Santa Barbara, have made a groundbreaking discovery about how marine bacteria acquire iron from seawater. The marinobactin and aquachelin siderophores, produced by these bacteria, exhibit a unique ability to bind to iron and form vesicles, raising questions about their physiological role.
The XMM-Newton satellite is now operational, sending home images of celestial objects and observing bright binary stars, pulsars, and cataclysmic variables. It will study massive black holes and exotic stars, mapping the cosmos to greater distances.
A new study links human breast cancer to the mouse mammary tumor virus, proposing that humans acquire the virus from infected mice. The authors found a similar viral sequence between human breast cancer and mouse mammary tumor virus, suggesting a potential preventive vaccine.
A groundbreaking study published in Nature reveals that many coral reef fish spend their life cycle close to home, rather than drifting in the open ocean. This finding has significant implications for marine conservation and fisheries management, as it challenges the prevailing view of larval dispersal.
Researchers discovered strong evidence of a 55.5 million-year-old global warming event linked to a massive methane release. The 'latest Paleocene thermal maximum' led to the extinction or disappearance of deep-sea species and changed ecosystems. Further research is needed to understand this phenomenon.
A team of scientists discovered the oldest known dinosaur fossils in Madagascar, dating back to 230 million years ago. The fossils were found by a young local boy named Mena who led researchers to a hill with a mound of bones, sparking an eight-year dig that yielded spectacular results.
A team of paleontologists has discovered jaws from two of the oldest dinosaurs ever found, along with eight other prehistoric animals, in a rich bed of fossils in Madagascar. The discovery provides a unique glimpse into the mid-late Triassic Period and illuminates scientific understanding of this era.
A captive breeding program aims to replenish the nearly decimated population of white abalone by leveraging their unique reproductive needs. The mollusks require close proximity with an opposite sex for fertilization, hindering effective reproduction and making conservation efforts challenging.
Three tiny teeth found in a piece of lower jawbone from a small Jurassic period mammal on Madagascar's island, contradicting widely-held ideas on mammalian evolution. The discovery more than doubles the age of the oldest known mammal from Madagascar and provides new insights into early branching events in the family tree of mammals.
Researchers are working to create a better lung surfactant mixture that can be easily produced without batch variance, tailored to specific cases. The new formulation aims to reduce mortality rates by 30-50% for infants with neonatal respiratory distress syndrome.
Researchers successfully eliminated an invasive South African worm that was causing deformed shells and stunted growth in California's abalone. By removing susceptible snails and using the 'epidemic threshold of transmission theory,' they were able to break the parasite's cycle, offering a new glimmer of hope for conservation efforts.
Researchers found that oxygen supplementation can significantly reduce the effects of retinal detachment by protecting photoreceptor cells and limiting cell abnormality. This breakthrough suggests that ophthalmologists may want to consider providing oxygen therapy to patients diagnosed with retinal detachment while awaiting surgery.
Researchers at UC Santa Barbara discovered a unique protein-based adhesive that explains the abalone shell's exceptional fracture resistance. This 'biological rubber' helps maintain its structure by releasing sacrificial links that break before the whole molecule, providing both strength and elasticity.
Researchers at University of California, Santa Barbara have discovered a way to disarm microbial pathogens using a novel approach. The findings, published in Science, identify a master switch that controls bacterial infection and lead to the development of new vaccines and antibiotics.
The Yanomamo tribe, numbering around 25,000, is facing a major survival crisis due to the devastating floods in Venezuela's Amazon region. The flooding has imperiled clusters of Yanomamo living near the Orinoco River and destroyed their staple food crops, leading to increased sicknesses and potentially uncontrollable epidemics.
