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 ...
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.
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.
Study finds unexpected link between cell suicide and longevity
What is the secret to aging more slowly and living longer? Not antioxidants, apparently.
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 ...
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.
Chemists develop new way to kill cancer cells resistant to the chemotherapy drug cisplatin
A new study from MIT and the University of Toronto offers a possible way to overcome that resistance. The researchers found that when cisplatin was delivered to cellular structures called mitochondria. DNA ...
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.
How birds lost their penises
In animals that reproduce by internal fertilization, as humans do, you'd think a penis would be an organ you couldn't really do without, evolutionarily speaking. Surprisingly, though, most birds do exactly ...
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. ...
Preventing cell death from infection: Scientists demonstrate method to find new therapies
Scientists at The Scripps Research Institute (TSRI) have demonstrated the power of a new drug discovery technique, which allows them to find—relatively quickly and cheaply—antibodies that have a desired ...
Researchers develop mitoflash technique to predict lifespan of nematodes
Researchers find unfolded-protein-response can both activate and degrade cell death receptor 5 protein
A major hub for cell-fate decisions
In a recently published study, LMU researchers show that, in a nerve-cell lineage in the nematode Caenorhabditis elegans, a single protein controls the rate of cell-cycle progression, and decides whether cells divide, differentiate ...
