The older we get, the less likely we are to hear well, as our inner ear sensory hair cells succumb to age or injury. Intriguingly, humans are one-upped by fish here. Similar hair cells in a fish sensory system that dots their bodies and forms the lateral line, by which they discern water movement, are readily regenerated if damage or death occurs.

Researchers have developed a new informatics technology that analyzes existing data repositories of protein modifications and 3D protein structures to help scientists identify and target research on “hotspots” most likely to be important for biological function.

Palaeontologist Dr Gareth Dyke writes for The Conversation about the scientific debate around the new Jurassic World film

Data from 20 million cells collected by U of T researchers to develop detailed cell map.

Microfluidic cell-squeezing device opens new possibilities for cell-based vaccines.

Thawing cells in a regulated environment presents many challenges. The need to minimize variability through standardization is crucial. Whereas the science of cell freezing has become highly standardized in order to improve and retain optimal viability and function, cell thawing has been overlooked and has much to gain from similar standardization.

Gel permeation chromatography (GPC) is the most widely accepted and used analytical method for  obtaining molar mass averages of both synthetic and biopolymers. Traditionally, molar mass averages are obtained via a peak position calibration involving a series of standards of known molar mass and chemistry analyzed by GPC coupled to a differential refractive index (RI) detector.

Cell-based assays have become the go-to technology for pharmaceutical, environmental, and toxicology labs. Cells are far less costly to maintain than test animals and don’t involve the ethical considerations. But the complexity of cell-based assays compared with chemical or biochemical assays presents distinct challenges to laboratory managers.

Horizon Discovery Group plc (LSE:HZD) (Horizon), the international life science company supplying research tools and services that power genomics research and the development of personalized medicines, today (Apr. 20) announced it has signed a supply and commercialization agreement with Thermo Fisher Scientific, the world leader in serving science.

Problem: The human genome encodes thousands of secreted proteins, each of which is an actor in
the delicate biochemical balance of diagnostics. Even a slight change in any one of these proteins can
mean the difference between sickness and health. Such a change also provides a critical window into
the body and helps to direct diagnosis and treatment, however, the vast majority of secreted proteins
are present in concentrations well below what conventional technologies can measure, and their role in
human health is poorly understood.

New details revealed in the coordinated regulation of large stretches of DNA.

Collaborating scientists from The Scripps Research Institute (TSRI) and the University of California (UC) San Diego have developed a powerful new system for studying how proteins and other biological molecules form and lose their natural folded structures.
