New project aims to make large-scale lobster farms feasible

...ct larvae from the wild. The lobster larval growth cycle is extremely complicated and as yet reproduction and growth to adulthood has not been accomplished in captivity in reliable numbers. Development of collection methods to get enough larvae to support large-scale commercial culture has so far not been...

One gene links newborn neurons with those that die in diseases such as Alzheimer's

...ts of the brain, cells called neurons go through a cycle of death and replenishment. New research from Rockefeller University's Fernando Nottebohm, Ph.D., shows that these replaceable neurons share something in common with the neurons that die in people with diseases such as Alzheimer's and Parkinson's: bo...

Study reveals candidate targets for anti-retroviral therapeutics

...s encoded by Ty elements and the steps of the life cycle in yeast are similar to the proteins encoded by retroviruses and their life cycles in animal cells. Scientists believe that these simple elements in a single-celled organism are a good model for understanding how retroviruses such as HIV interact wit...

Product improves peptide identification for proteomics research

... Trap XCT Ultra offers significantly improved scan cycle times, enabling collection of mass spectra at rates up to three times faster than its predecessors. "The combination of the new LC/MSD Trap XCT Ultra with Agilent's breakthrough HPLC-Chip/MS technology will set a new standard for protein identificat...

High fidelity keeps human DNA assembly line humming

...nthesis can lead to cancer or can support the life cycle of an invading virus. Researchers consider control of RNA synthesis to be a huge issue in human health. It is also the foundation of how living systems function. In the world of molecular biology, much attention has been given to how RNA is made. Bu...
