Brain tumor cells decimated by mitochondrial 'smart bomb'
An experimental drug that attacks brain tumor tissue by crippling the cells' energy source called the mitochondria has passed early tests in animal models and human tissue cultures, say Houston Methodist ...
Scientists unlock key to cancer cell death mystery
An international team of scientists has announced a new advance in the ability to target and destroy certain cancer cells.
Mitochondria and the great gender divide
(Medical Xpress) -- Why are there two sexes? Its a question that has long perplexed generations of scientists, but researchers from UCL have come up with a radical new answer: mitochondria.
Star Wars-inspired bacterium provides glimpse into life
(PhysOrg.com) -- A bacterium whose name was inspired by the Star Wars films has provided new clues into the evolution of our own cells and how they came to possess the vital energy-producing units called mitochondria.
Team uses nanoparticles to enhance chemotherapy
(Phys.org) —University of Georgia researchers have developed a new formulation of cisplatin, a common chemotherapy drug, that significantly increases the drug's ability to target and destroy cancerous cells.
The vital question: Why is life the way it is?
How gold nanoparticles can help fight ovarian cancer
Positively charged gold nanoparticles are usually toxic to cells, but cancer cells somehow manage to avoid nanoparticle toxicity. Mayo Clinic researchers found out why, and determined how to make the nanoparticles effective ...
Songbirds may have 'borrowed' DNA to fuel migration
A common songbird may have acquired genes from fellow migrating birds in order to travel greater distances, according to a University of British Columbia study published this week in the journal Evolution.
Key cellular mechanism in the body's 'battery' can either spur or stop obesity
Becoming obese or remaining lean can depend on the dynamics of the mitochondria, the body's energy-producing "battery," according to two new studies by Yale School of Medicine researchers featured as the ...
Researchers discover new organism: Finding will help scientists understand the origins of multicellular life
Researchers at the University of Arkansas have discovered and characterized a new organism that will help scientists understand the molecular mechanisms and ancestral genetic toolkit that enabled animals ...
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 ...
Amoeba offers key clue to photosynthetic evolution
(PhysOrg.com) -- The major difference between plant and animal cells is the photosynthetic process, which converts light energy into chemical energy. When light isn't available, energy is generated by breaking ...
Mapping subcellular temperature profiles with genetically-encoded thermosensors
New sensor tracks zinc in cells, could be exploited for early diagnosis of prostate cancer
Zinc, an essential nutrient, is found in every tissue in the body. The vast majority of the metal ion is tightly bound to proteins, helping them to perform biological reactions. Tiny amounts of zinc, however, ...
