Talented sniffer: A receptor known for guiding sperm to egg plays a role in the nose

...tory receptor proteins. Having sperm successfully locate the egg is a crucial step in fertilization. Recent evidence had shown that hOR17-4, a human olfactory receptor protein that is unconventionally expressed on sperm cells, appears to play a key role in sperm-egg communication and chemotaxis prior to ga...

UF scientists have bionanotechnology recipe to find elusive bacteria

...ows. Dye-labeled antibodies are commonly used to locate bacteria in a sample, but traditional methods are not very sensitive -- the glow from one antibody-linked dye molecule just isn't easy to see, and that can create potential health risks. "Sometimes one bacterium makes the difference," Tan said. The...

Arctic mystery no longer: Dinosaurs walked Canada's great north

...es per day for one month with his research team to locate bones during the summer of 2003 and 2004. "You wouldn't expect it, yet dinosaurs and a great variety of plants lived in the High Arctic 240 to 65 million years ago." These were Larsson's first Arctic expeditions. He has also visited Western Africa fi...

Stimulating nerve cells with laser precision

... the procedure, making it tedious and difficult to locate the exact nerve. Optics, on the other hand, can deliver laser precision by stimulating only the nerve cell of interest. The idea of optical stimulation started as the scientists questioned whether they could accurately detect the...

NIH makes award to UNC for Genome Fingerprint Scanning program

...notated genetic sequences to identify proteins and locate novel genes. Proteomics, the study of how proteins interact and respond to changing conditions in complex systems, is increasingly being used to help decipher diseases such as cancer, diabetes, and Alzheimer's. "This powerful genome fingerprint scan...

Academy meeting highlights advances in detecting Amish, Jewish, and Icelandic genetic diseases

...lt of the Human Genome Project, we are now able to locate genetic mutations and know much more about a person's medical future than ever before. For genetic diseases that are endemic among certain peoples, such as the Icelandic, Ashkenazi Jewish, Old World Amish, and Micronesian populations, genetic testin...

Scientists uncover clues to the mystery of 'gene deserts'

...ve the paradox and to help researchers more easily locate critical segments along the vast stretches of DNA deserts, scientists from LLNL, LBNL, and the Pennsylvania State University developed computational tools to decipher gene regulation by comparing the genomes of many different species. When the...

New technique for tracking gene regulators

Hypertension in African Americans linked to two genomic regions

.... Researchers can now use this information to help locate genes affecting hypertension. "When a specific gene variant associated with hypertension is identified, physicians will be able to test patients for their risk of hypertension to head it off early," Rao says. "In addition, research institutions and p...

UCI researchers identify trigger for onset of Alzheimer's, aiding search for new therapies

After the platform was removed, the researchers monitored in subsequent trials how fast the mice swam to where the platform used to be an indication...

Heart Center cardiologist performs rare liver catheter intervention on teen

Justino then deployed a mesh-like occluder device through one of the catheters, thus filling the liver's large abnormal vein. The new device now blocks the sh...

Plants defy Mendel's inheritance laws, may prompt textbook changes

"It seems that these hothead-containing plants keep a cryptic copy of everything that was in the previous generation, even though it doesn't show up in th...

Legendary Siberian tiger, Olga, killed by poachers

... Since January, however, they have been unable to locate her signal despite extensive aerial and ground searches over an area of about 10,000 square kilometers (3,800 square miles). Staff of the Siberian Tiger Project have documented many cases in which lost signals from radio collars are a result of poac...

Molecular motors cooperate in moving cellular cargo, study shows

...ing with One Nanometer Accuracy. The technique can locate a fluorescent dye to within 1.5 nanometers (one nanometer is a billionth of a meter, or about 10,000 times smaller than the width of a human hair). Recent improvements to FIONA now allow scientists to detect motion with millisecond time resolution. S...
