Genetic Mutations Can Be Benign or Cancerous—a New Method to Differentiate Between Them Could Lead to Better Treatments
Ryan Layer, The Conversation | May 27, 2022 | 5 min read
Tumors contain thousands of genetic changes, but only a few are actually cancer-causing. A quicker way to identify these driver mutations could lead to more targeted cancer treatments.

Drug Makers on the Apoptotic Trail
Ted Agres | Jun 24, 2001 | 4 min read
Apoptosis, a key process in the development of embryonic tissue differentiation, later helps to regulate the normal cellular life cycle by destroying damaged cells. When something goes awry, too little apoptosis can make cancer cells resistant to chemotherapy and even death-defiant. At the other extreme, premature or excessive apoptosis has been linked to neurodegenerative diseases, such as Alzheimer's, and to nerve cell loss in strokes. Not surprisingly, many major pharmaceutical companies rec

For Olfaction, a Hypothesis is Felled

Peter MombaertsCourtesy of Peter MombaertsRarely do scientific studies claim that something is not the case. Rarer still do negative results appear in top-tier journals. Yet two recent papers in Nature describe what olfactory sensory neurons do not do.12The olfactory system is often compared to the immune system. The key cell types in each system, the olfactory sensory neuron (OSN) and the lymphocyte, can detect a wide variety of chemicals, both natural and synthetic. Chemical recognition by the

Aptamers Identify Protein Signatures
Ricki Lewis | Apr 1, 2001 | 3 min read
Graphic: Leza BerardoneA technique not deemed "sexy" enough for commercialization a decade ago may finally find its niche in proteomics. SomaLogic Inc. of Boulder, Colo. is pioneering aptamers, which are modified DNA molecules that bind specific proteins in body fluid samples. Aptamers are initially selected for specific binding activities from a huge starting pool, then variants are obtained during subsequent rounds of amplification. The technology builds on the ability of aptamers to bind tena
