A mating strategy among redback spiders where males seek out immature females appears to benefit both sexes, a new U of T Scarborough study has found.
Salk scientists develop new approach to identify important undiscovered functions of proteins.
Wistar scientists revealed the mechanism implicated in the defective function of tumor-associated dendritic cells (DCs), a specialized type of immune cells that expose the antigens on their surface to activate the T cells.
Researchers at the University of Colorado Anschutz Medical Campus have discovered that color vision in mice is far more complex than originally thought, opening the door to experiments that could potentially lead to new treatments for humans.
Indiana University researchers have identified a way to block the ability of parasites that cause malaria to shield themselves against drug treatments in infected mice--a finding that could lead to the development of new approaches to combat this deadly disease in humans.
A genetic mutation that occurred over 700 million years ago may have contributed to the development of certain organs in human beings and other vertebrates. This change, a random error in the evolutionary process, facilitated the connection of the gene networks involved in animal embryogenesis. The study, published in the journal Nature Communications, was participated in by experts from the Centre for Genomic Regulation, the Department of Genetics from the University of Barcelona Institute of Biomedicine, and the Anton Dohrn Zoological Station in Italy.
Danish researchers have just presented a previously unknown mechanism that inhibits the ability of cells to develop into cancer cells.
A new study led by SBP describes the biology behind why muscle stem cells respond differently to aging or injury. The findings, published in Cell Stem Cell, have important implications for the normal wear and tear of aging.
A team of Arizona State and Harvard scientists has invented a major new advance in DNA nanotechnology. Dubbed 'single-stranded origami,' their new strategy uses one long, thin noodle-like strand of DNA, or its chemical cousin RNA, that can self-fold -- without even a single knot -- into the largest, most complex structures to date. The strands forming these structures can be made inside living cells, opening up the potential for nanomedicine.
Helping to make creation of nano-sized structures more user-friendly, scientists have designed single-stranded DNA and RNA (ssDNA and ssRNA) that can fold into desired shapes on command, and at an unprecedented scale.
