Potential vaccine developed for deadly leishmaniasis disease

...ck with carbohydrate vaccines is the difficulty in getting them to produce a strong immune response. Vaccine manufacturers achieve this by adding a booster substance ?an adjuvant. The standard existing adjuvant, alum, has limitations. Potential alternative adjuvants are toxic, expensive or have other problem...

'Nano-keys' bind cell receptors and trigger allergic reactions

...e cells are binding to the engineered surfaces and getting turned on. We can then see how the cell is organizing itself due to the stimulus." Collaborators include: David Holowka, Cornell senior scientist in chemistry; and the research groups of Harold G. Craighead, Cornell professor of applied and engineer...

Expedition discovers marine treasures

... Antilles (MINA), called the expedition crucial to getting the area protected to benefit local populations. "The community of about 1,500 people on nearby Saba Island derives a large part of its economy from the atoll, and the atoll is being damaged," Hoetjes said. A petroleum trans-shipment depot on neigh...

Study finds evolution doesn't always favor bigger animals

...of life today, they've all been adapted to a world getting gradually cooler," said Roy. "But our future is destined to be significantly warmer. What are animals going to look like when everything must adapt to a warmer world? Size correlates with many aspects of the biology of an animal so changes in size ar...

Study outlines genetic differences between potential pandemic influenza strains

...e potential to cause a human influenza pandemic is getting more genetically diverse, which makes studying the virus more complex and heightens the need for increased surveillance. She expects further continued diversity in the future. "Change is the only constant. Only time will tell whether the virus evo...

Forsyth scientists gain greater understanding of how embryos differentiate left from right

...ining a significant understanding of asymmetry and getting closer to understanding its impact on humans. This fascinating ion pump has additional roles during development that are a goldmine of novel cellular control mechanisms." Dr. Levin's team looked at molecular genetic and physiological characterizatio...

Rare Chinese frogs communicate by means of ultrasonic sound

...sibility of unusual hearing abilities. "Now we are getting a better understanding of why their ear drums are recessed," Feng said. "Thin eardrums are needed for detection of ultrasound. Recessed ears shorten the path between eardrums and the ear, enabling the transmission of ultrasound to the ears." To test...

UCLA scientists uncover mechanism of response to targeted therapy

...ve tests," Thomas said. "This would save them from getting an added surgical procedure. And we can see, in a very short time, probably in less than a week, whether the drug is working." The study was a collaboration of researchers from the Jonsson Cancer Center, the Crump Institute for Molecular Imaging, th...

Molecular mechanism may explain how fevers spark seizures

...ntaining mutant gamma subunits were not as good at getting to the neuronal cell surface, and Kang wondered what would happen to these receptors when they were exposed to high temperatures. She raised the temperature of cells expressing the mutant receptors to 40 degrees Celsius, simulating a "fever" of 104 d...

New antimicrobial compound adheres to skin to promote healing

...y settings. "In high-school athletics especially, getting staph infections from scratches is a huge problem. Our bioadhesive can adhere to wet skin, cleanse the wound and promote healing," he said, adding that they're also looking at a non-oily gel formulation for use as a combination cleanser and ointment ...

Hamon Distinguished Chair in Basic Cancer Research. The study is available this week online and in an upcom...

Scientists force viruses to evolve as better delivery vehicles for gene therapy

...ng the virus to cells it is ordinarily not good at getting into, or speeding its transport through the body," he said. Though Schaffer acknowledges that the technique could be used to help pathogenic viruses evade the human immune system, potentially making them more virulent, he said that other and easier ...

Parachuting allows krill to eat and run

...stomachs are full and may be an effective means of getting out of harm's way when they can eat no more. It is estimated that Antarctic krill sequester 0.02 metric gigatons of carbon per year through this behavior, equivalent to the annual carbon emissions of 35 million cars. ...
