Gelatin nanoparticles could deliver drugs to the brain
Stroke victims could have more time to seek treatment that could reduce harmful effects on the brain, thanks to tiny blobs of gelatin that could deliver the medication to the brain noninvasively.
New research solves old mystery of silent cell death
Walter and Eliza Hall Institute researchers have for the first time revealed how dying cells are hidden from the immune 'police' that patrol the body.
Arming nanoparticles for cancer diagnosis and treatment
UCD researchers have successfully manipulated nanoparticles to target two human breast cancer cell lines as a tool in cancer diagnosis and treatment.
Toxin targets discovered
Research that provides a new understanding of how bacterial toxins target human cells is set to have major implications for the development of novel drugs and treatment strategies.
Scientists develop 3-D model of regulator protein bax
Scientists at Freie Universität Berlin, the University of Tubingen, and the Swiss Federal Institute of Technology in Zurich (ETH) provide a new 3D model of the protein Bax, a key regulator of cell death. When active, Bax ...
Geometry, programmed death might have enabled evolution of multicellularity
Geometry and programmed cell death may have helped along the evolution of multicellular life, according to new research led by SFI Omidyar Fellow Eric Libby.
Synthetic molecule makes cancer self-destruct
Researchers from The University of Texas at Austin and five other institutions have created a molecule that can cause cancer cells to self-destruct by ferrying sodium and chloride ions into the cancer cells.
Researchers investigate remarkable approach to desalination
Desalination has come a long way, baby. On Aug. 3, some 330 years ago, a certain Captain Gifford of His Majesty's Ship Mermaid, was asked to conduct onboard his 24-gun Royal Naval vessel what may have been ...
Researchers find unfolded-protein-response can both activate and degrade cell death receptor 5 protein
Discovery of a primordial cancer in a primitive animal
Every year around 450,000 people in Germany are diagnosed with cancer. Each one of them dreams of a victory in the battle against it. But can cancer ever be completely defeated? Researchers at Kiel University ...
Scientists reveal details of calcium 'safety-valve' in cells
(Phys.org) —Sometimes a cell has to die—when it's done with its job or inflicted with injury that could otherwise harm an organism. Conversely, cells that refuse to die when expected can lead to cancer. ...
MEMS nanoinjector for genetic modification of cells
The ability to transfer a gene or DNA sequence from one animal into the genome of another plays a critical role in a wide range of medical research—including cancer, Alzheimer's disease, and diabetes.
New method sneaks drugs into cancer cells before triggering release
(Phys.org) —Biomedical engineering researchers have developed an anti-cancer drug delivery method that essentially smuggles the drug into a cancer cell before triggering its release. The method can be likened ...
Study finds unexpected link between cell suicide and longevity
What is the secret to aging more slowly and living longer? Not antioxidants, apparently.
