Stealth Worms May Improve Insect Pest Control

...ckly. Depending on climate conditions, this method works best on greenhouse ornamentals and vegetables, citrus, cranberry, turfgrass and other crops, rather than on high-acreage crops like cotton and soybeans. "The beauty of this is that in the last 20 years nematodes have been formulated and commercializ...

Molecular thermometers on skin cells detect heat and camphor

...the most fundamental of our five senses because it works through our largest organ, the skin. Through the skin we can detect temperature, texture, and understand both pleasure and pain. A few years ago, the Scripps Research and GNF team, which was led by Scripps Research Assistant Professor Ardem Patapout...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...of signaling enzymes known as serine proteases and works by cutting the amino acid chain of other proteins. Romesberg and his colleagues showed that LexA's action was necessary for the evolution of resistance to the antibiotics in vitro. The effect in vivo was dramatic. Blocking LexA in rodent models of E...

Sugar beet virus mutation requires Texas touch

... in Minnesota and North Dakota, Rush said his team works with growers and sugar company representatives at harvest time. Soil samples and infected beets are brought back to the lab at Bushland. Sugar beets are planted in the contaminated soil and the virus is purified from the infected plants, he said. Th...

Researchers working on abnormalities in the kidneys will also benefit from the improved scanning, research is currently underway at the University to investigate vascular ...

Mutation in clams protects against paralytic shellfish poisoning but raises human health risk

...red tide)." Betty Twarog, a neurophysiologist who works at UMaine's Darling Marine Center in Walpole, Maine, did research in the 1960s and 1970s showing that PSP toxin resistance varies among shellfish species. In laboratory studies, the investigators exposed clams to PSP toxins and monitored the shellfi...

Chemists synthesize molecule that helps body battle cancers, malaria

Second messenger NAADP shows fast, dose-related impact on satiety cycle

...t to be a so-called "second messenger," because it works from inside cells, rather than externally. However its mode operation remains unknown ?and controversial in several aspects. Results of a new study "establishes NAADP as a new second messenger, and the study of this novel molecule has potential to e...

Understanding how bacteria communicate may help scientists prevent disease

...lent invader," said Rahul Kulkarni. While Kulkarni works with Vibrio cholerae as a model bacteria, quorum sensing appears to be a universal process in bacteria. So what he learns about the communication process known as quorum sensing could one day help scientists prevent a broad range of diseases caused b...

Moffitt-USF head toward first human trials of anti-cancer drug that targets protein AKT

...y. The Moffitt-USF team discovered that tricirbine works only against tumors in which the cancer-causing Akt protein is abundant and/or abnormally active. "These tumors are addicted to hyperactive Akt and cannot survive without it," explains Saïd Sebti, Ph.D., Moffitt's Manuel and Adeline Garcia Professor...

Newest HIV drugs should be used with FUZEON(R)

Mosaic mouse technique offers a powerful new tool to study diseases and genetics

..., which Luo and his colleagues developed for mice, works on the same principal as the method currently used to create mosaic fruit flies. The researchers begin with two embryonic stem cells whose chromosomes have been engineered to carry two inactivated segments of a green fluorescent protein molecule. Mic...

Morphine for Chest Pain Increases Death Risk
