Rising ocean temperatures, pollution have oysters in hot water

... she said. In addition to filtering water, oysters create a kind of reef that other marine life depends upon. "Studies have shown that there are more than 300 species reliant on oyster reefs, including at least 12 species important for their commercial or recreational value, such as blue crabs, sheepshea...

Report calls for improved monoclonal antibodies against solid tumors

... the nearly 20 years since scientists were able to create monoclonal antibodies that could be safely used in humans, eight monoclonal antibodies have been approved for use in clinical treatments to trigger immune responses to cancer cells, modulate cancer cell growth, and deliver drugs to cancer cells. Of t...

Genetic study of Neanderthal DNA reveals early split between humans and Neanderthals

...hod to clone and insert missing fragmented DNA and create a library of Neanderthal DNA. Unlike the libraries used to sequence the human genome, which contained only human DNA fragments, the Neanderthal DNA library is riddled with contamination from microbes that lived off the nutrients in the Neanderthal ...

Novel regulatory mechanism identified for key tumor suppressor p53

...ively small proteins around which DNA is coiled to create structures called nucleosomes. Compact strings of nucleosomes, then, form into chromatin, the substructure of chromosomes. With histones, methylation is well recognized as a regulatory mechanism, but the fact that other proteins are also be modifie...

U of S Vaccine and Infectious Disease Organization team discovers key step in flu virus replication

...information will help the researchers learn how to create harmless influenza viruses that can be used as live vaccines. The pathway can be thought of as an assembly line with a switch to turn it on, says Zhou. "If the switch is turned on, the pathway enables efficient production of more viruses. But on...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

...sing that the researchers are currently working to create an online encyclopedia of Raman shift values. With that information, a technician could readily reference a Raman shift for a particular virus to identify an unknown virus. To make their finding commercially viable, they're developing a business m...

Ferns provide model for tiny motors powered by evaporation

Scientists looked to ferns to create a novel energy scavenging device that uses the power of evaporation to move itself---materials that could provide a method for powering micro and nano devices with just water or heat. "We've shown that this idea works," said Michel Maharbiz, assista...

Nano-devices hold promise for early-stage cancer detection

... high-profile interdisciplinary research. It will create novel and exciting learning environments for training, and attract new industrial partnerships." Plans call for the lab to occupy approximately 9,600 square feet and include a clean room, bonding and packaging facilities, characterization faciliti...

Single molecular 'mark' seen as pivotal for genome compaction in spores and sperm

...ively small proteins around which DNA is coiled to create structures called nucleosomes. Compact strings of nucleosomes, then, form into chromatin, the substructure of chromosomes. To test the team's observations, Krishnamoorthy performed an experiment in yeast in which she altered the histone's chemical c...

High HPV concentrations combined with smoking significantly raise risks of cervical cancer

... Gunnell's study, in fact, suggests that both may create a biochemical synergy that propels the disease. The researchers looked at "Pap" smear examination data from 105,760 Swedish women and identified 499 women with cervical cancer in situ, along with 499 cancer-free women as controls. For these women, t...

Researchers create genetically matched embryonic stem cells for transplantation

... another method, somatic cell nuclear transfer, to create customized embryonic stem cells to repair genetic ... Stem Cell Institute-associated labs attempting to create human embryonic stem cells with that technique. "However, generating embryonic stem cells from unfer...

Experimental vaccine protects mice against deadly 1918 flu virus

... have imagined five years ago that we'd be able to create a vaccine that protects against one of the deadliest forms of influenza the world has ever seen?" adds Dr. Nabel. "It's because the 1918 flu virus has been reconstructed that we are now able the further understand it. Hopefully, this virus will help ...

Researchers barcode DNA of Venice museum's vast fungi collection

...and best preserved collection of fungi in Italy to create an unprecedented DNA database. These 28,000 samples of fungi that represent 6,000 species - many of which are quite rare - are housed at the Venice Museum of Natural History, a partner with UC Berkeley for this ambitious project. The collection also...

Pleasure and pain: Study shows brain's 'pleasure chemical' is involved in response to pain too

...using magnetic resonance imaging (MRI) in order to create a precise map of the brain's structure, and combined that with their PET scans to find the exact areas of dopamine activity. The volunteers answered questions from two standardized questionnaires repeatedly both in a control (no pain) state and w...

Paramecia adapt their swimming to changing gravitational force

...stable, so Valles and Guevorkian were also able to create conditions simulating zero-gravity and inverse-gravity. By dialing the magnetic field up or down, the researchers could change the swimming behavior of the paramecia dramatically. In high gravity, the organisms swam upward mightily to maintain their...

Cardiologist's 'living chip' changes science of disease monitoring

...ors ?integrating living cells with electronics ?to create a "biological chip." When implanted, this chip can detect physiologic and chemical changes with faster, improved accuracy. These more accurate results, retrieved without invasive testing, allow for better and timely response and, the hope is, a healt...

Study: Living coral reefs provide better protection from tsunami waves

...idealize a number of factors, because we wanted to create a model that could be used for a general shoreline," Kunkel said. "For example, we had to consider a perfectly even ocean floor, because uneven ones can funnel a wave into a certain area." Despite the limitations of the model, Oppenheimer said it p...

Three-dimensional, miniature endoscope opens new diagnostic possibilities

... two waves of light, provides the data required to create three-dimensional images. To demonstrate the device's application in a live animal, the researchers used the system to image metastatic ovarian tumors on the abdominal wall of a mouse. The SEE probe was passed into the abdominal cavity through a...
