Portable cocaine sensor developed at UC Santa Barbara

...to continue her studies in the sciences, either in biochemistry or biology. McCall Wood said, "I'm really excited about this work. It let me know what research is like and I definitely want to pursue this. Everyday we would go into the lab and test a different hypothesis. I found it really exciting and extremel...

Picking particles faster than one at a time

...ife Sciences Divisions, who is also a professor of biochemistry and molecular biology at the University of California at Berkeley, calls "crystallization in silico." "In theory, you need twice as many particles as the molecular weight of what you want to image," explains Umesh Adiga, a member of Glaeser's labor...

'Computer-chemistry' yields new insight into a puzzle of cell division

...lph, the Duke assistant professor of chemistry and biochemistry who led the research. "It's very exciting. I think it's a really hard problem." A successful docking between the two enzymes not only requires the "active sites" -- where chemical reactions occur --on the phosphatase and the kinase to link precisely...

Biologists discover new pathway into plant cells

...it does," said Andrew Karplus, an OSU professor of biochemistry and biophysics. "And with work done by a graduate student, Ganapathy Sarma, we also now have a clear understanding of what the molecular structure of the toxin looks like. With continued research, we should not only be able to determine how the prote...

New U. of Colorado at Boulder flu chip may help combat future epidemics, pandemics

...oulder Professor Kathy Rowlen of the chemistry and biochemistry department. Current methods for characterizing flu subtypes infecting patients take about four days. The Flu Chip is expected to be in wide use in laboratories within a year, said Rowlen, who has led the two-year CU-Boulder research effort. Rowlen...

The nude mouse tale: Omega-3 fats save the life of a terminal cancer patient

... few months to live," said Pardini, a professor of biochemistry and associate director of the Nevada Agricultural Experiment Station at the University of Nevada, Reno. "But five years later, he is still alive, and has even gained a little weight." The cancerous tumors found in D.H.'s lungs have shrunk to 10 per...

Cancer support cells may evolve, fuel tumor growth, study shows

...said Dr. Terry Van Dyke, professor of genetics and biochemistry and biophysics in the School of Medicine, member of the UNC Lineberger Comprehensive Cancer Center and the study's senior author.Thus, research focused solely on the predominant cancer cell, such as epithelial cells that form the bulk of many tumors ...

Scientist uses form to explain function of key building blocks of life

...of the National Academy of Sciences. Professor of biochemistry John Markley, along with a team that included graduate student I-Jin Lin, studied iron-sulfur proteins called rubredoxins that transfer energy in the form of electrons throughout living systems. Rubredoxin is a key part of processes like photosynth...

Novel enzyme offers new look at gene regulation

...Yi Zhang, the lead author. Zhang is professor of biochemistry and biophysics at UNC's School of Medicine and the university's first Howard Hughes Medical Institute investigator. He also is a member of the UNC Lineberger Comprehensive Cancer Center. The new study is now online in the journal Nature. "Human gen...

Free-energy theory borne out in large-scale protein folding

...Pernilla Wittung-Stafshede, associate professor of biochemistry and cell biology, Matthews and graduate student Corey Wilson of biochemistry and cell biology. "We know that misfolded proteins play a key but mysterious role in Alzheimer's, P...

Sperm stem cells closer to being like embryonic stem cells

Novel protein complex enables survival in hostile environment

...from published works by Robert White, professor of biochemistry at Virginia Tech, who studies how metabolic systems evolved and collaborates with Mukhopadhyay. "It is possible that M. jannaschii had this enzyme for cofactor biosynthesis and having it in advance gave the organism a selective advantage when oxygen,...

University of Delaware researchers develop cancer 'nanobomb'

... a team that includes Eric Wickstrom, professor of biochemistry and molecular biology at Thomas Jefferson University in Philadelphia, and his student Greg Cesarone, and UD graduate students Shaoxin Lu, Kousik Sivakumar and postdoctoral researcher Kasif Teker. Panchapakesan received his bachelor' TM s degree in...

Student scientists create living bacterial photographs

...dents' faculty advisers and associate professor of biochemistry at The University of Texas at Austin. "This is a great example of the emergent field of synthetic biology--using principles of engineering in biology." "We're making bacteria that are all independently functioning computers and we can get them to do...

New classification of eukaryotes has implications for AIDS treatment, agriculture and beyond

...sification conveys important information about the biochemistry and metabolism of disease-causing organisms. The new classification recognizes 6 major clusters of organisms, rather than the 4 traditional Kingdoms. Here are three examples. 1) Pneumocystis, an opportunistic pathogen causing mortality in AIDS pati...

New discovery: If it weren't for this enzyme, decomposing pesticide would take millennia

...rd V. Wolfenden, Alumni Distinguished professor of biochemistry and biophysics at the UNC School of Medicine. "The half-life of the pesticide is longer, by several orders of magnitude, than the half-lives of other known environmental pollutants in water," Wolfenden said. "The half lives of atrazine, aziridine, p...
