NASA-funded robotic sub finds bottom of world's deepest sinkhole

A robotic vehicle designed for underwater exploration plunged repeatedly into the depths of Mexico’s mysterious El Zacatón sinkhole in late May, finding its previously undiscovered bottom 318 meters below the surface and generating a sonar map of its inner dimensions. The vehi...

Early exposure to indoor fungus molecules may protect infants against future allergies

...fectious ones that can develop resistance to drugs designed to eliminate them." Iossifova says further research is needed to determine how early microbial exposures affect the development of certain allergic conditions—including asthma, dermatitis and hay fever—later in life....

Keeping the immune system from starting a 'food fight'

...olic diseases, the researchers suggest. Treatments designed to reinforce that barrier may therefore provide the "next frontier" of therapies to combat the rising tide of chronic metabolic disease, they said. "Humans were not meant to deal with little to no exercise and a constant bombardment of nutrients,"...

Simple home spit test to spot deadly pre-eclampsia

A simple spit test designed to detect pre-eclampsia in the early stages is bei...ustry, the magazine of the SCI. The test, which is designed to be used at home, will allow mums-to-be to check for themselves whether they are at risk of the co...

Students invent protective pouch to enhance cell therapy

...tested biomaterials and constructed the prototype, designed to fit inside the portal vein. This large blood vessel, about the diameter of an index finger, carries blood from the digestive system into the liver. The pouch components are made to be compressed and inserted with catheters that a physician can...

Scientists identify prion's infectious secret

... sites within well-behaved proteins. Here, Tessier designed the arrays so that he could observe protein folding and amyloid formation in real time. Tessier covered the array with peptides from baker’s yeast and then added prion protein to the array, also from the same yeast species. He found that a small ...

Egyptians, not Greeks were true fathers of medicine

...gate the medicinal plants of ancient Egypt. He has designed his research to determine which modern species the ancient botanical samples are most related to. "This may allow us to determine a likely point of origin for the plant while providing additional evidence for the trade routes, purposeful cultivati...

WHO data confirms low level of resistance to Tamiflu

...ia, and pneumonia. About Tamiflu Tamiflu is designed to be active against all clinically relevant influenza viruses and works by blocking the action of the neuraminidase (NA) enzyme on the surface of the virus. When neuraminidase is inhibited, the virus is not able to spread to and infect other cells i...

Study shows continued success for new HPV vaccine against virus responsible for cervical cancer

...f HPV types 16 and 18. "It's the first vaccine designed specifically to prevent cancer," says Dr. Ault, on... HPV." To date there is no vaccine specifically designed to treat disease that is already established. Dr. Ault explains the current HPV vaccine is meant to...

DOE JGI sets 'gold standard' for metagenomic data analysis

... datasets in order to set a gold standard, we have designed the reference-simulated metagenome." Through the Nature Methods publication, Mavrommatis has invited others to contribute new methods as they arise to continue to update the server and sustain the value of the system. This is also facilitated thr...

Spreading viruses as we breathe

...dispersed in the air." As part of the study QUT designed and built a machine to measure the distance a droplet travels in the air prior to drying. "This droplet could potentially be carrying a virus," she said. "The significant part of our research has found that rather than the droplet falling direc...

Decoding protein structures helps illuminate cause of diabetes

...emists at the University of Wisconsin-Madison have designed a powerful analytical tool capable of measuring molecular structures quickly and accurately enough to catch moving proteins in mid-fold and see the shapes of intermediate steps. As described in this week's online issue of the Proceedings of the Nati...

Biodegradable microspheres deliver time release vaccines, stimulate different immune response

... used as a delivery system for a brain cancer drug designed to inhibit tumor growth. "It's like an Everlasting Gobstopper or a bar of soap. It wears away slowly over time, delivering its payload," says Wilson-Welder. The researchers vaccinated mice with microspheres loaded with ovalbumin, a protein fro...

Scientists see DNA get 'sunburned' for the first time

... in less than a picosecond. They took specially designed strands of DNA -- ones made solely of thymine bases, in order to boost the chance of observing a reaction between adjacent thymines -- and exposed them to UV light. Then they timed the reactions that caused the new thymine bonds to form. Kohler st...

Bones in motion: Brown scientists to create new 3-D X-ray system

...om a biomedical standpoint." The system will be designed and built with a $1.8-million grant from the W.M. Keck Foundation, one of the nation's largest philanthropic organizations and a major supporter of pioneering discoveries in science, engineering and medical research. The system will fill a v...

Natural antibiotics yield secrets to atom-level imaging technique

...ack viruses, fungi and even cancer cells, so drugs designed to mimic them could have widespread medical applications, said Ramamoorthy, who is an associate professor of chemistry and an associate research scientist in the Biophysics Research Division. While researchers have identified hundreds of AMPs in r...

Scientists identify pancreatic cancer stem cells

...m cells. They are resistant to traditional therapy designed for cells that rapidly turn over because stem cells don't, according to some researchers. Thus, they remain after tumors shrink and may be responsible for cancer recurrence and metastasis. This study confirms at least one of those concepts, the re...

NIH researchers discover protein that appears to regulate bone mass loss, the cause of osteoporosis

...s, is to determine whether experimental treatments designed to correct the immune deficiency of X-linked Hyper IgM Syndrome can also reverse the bone loss. If so, the knowledge gained from these studies may benefit people at risk of developing osteoporosis. ...
