Scientists make enzyme that could help explain origins of life
Mimicking natural evolution in a test tube, scientists at The Scripps Research Institute (TSRI) have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth.
Scientists resurrect 700-year-old viruses
Scientists' new analysis of plant proteins advances our understanding of photosynthesis
A world without plants would be a world without oxygen, uninhabitable for us and for many creatures. We know plants release oxygen by absorbing carbon dioxide and breaking down water using sunlight through ...
New studies bring scientists closer to combating dangerous unstable proteins
Scientists at The Scripps Research Institute (TSRI) have discovered a way to decrease deadly protein deposits in the heart, kidney and other organs associated with a group of human diseases called the systemic amyloid diseases.
First detailed picture of a cancer-related cell enzyme in action on a chromosome unit
A landmark study to be published in the October 30, 2014 print edition of the journal Nature provides new insight into the function of an enzyme related to the BRCA1 breast-cancer protein. The study by a t ...
Chamber of secrets: How cells organise themselves influences their ability to communicate
From basketball to handball, rugby to American football, teams in a variety of sports huddle together to agree tactics in secret. Cells, too, can huddle to communicate within a restricted group, scientists ...
Precise and programmable biological circuits
A team led by ETH professor Yaakov Benenson has developed several new components for biological circuits. These components are key building blocks for constructing precisely functioning and programmable bio-computers.
Bacteria are hard-wired for survival, E. coli study suggests
Some bacteria are able to thrive even when under continued attack, scientists have found, in a development that may help explain how our immune systems can't always prevent infections.
Sniffing out new repellents: Why mozzies can't stand the DEET
The smell of mozzie repellent is as much a part of summer as barbecues and the cricket. Despite supermarket and pharmacy shelves overflowing with insect repellents, there are actually only a few active ingredients ...
YEATS protein potential therapeutic target for cancer
Federal Express and UPS are no match for the human body when it comes to distribution. There exists in cancer biology an impressive packaging and delivery system that influences whether your body will develop cancer or not.
Right place, right time: Cellular transportation compartments
Proteins are the machinery that accomplishes almost every task in every cell in every living organism. The instructions for how to build each protein are written into a cell's DNA. But once the proteins are constructed, they ...
Imaging the genome: Cataloguing the fundamental processes of life
The team of researchers, led by Dr Rafael Carazo Salas from the Department of Genetics, combined high-resolution 3D confocal microscopy and computer-automated analysis of the images to survey the fission ...
Study gives new view on how cells control what comes in and out
A common protein plays a different role than previously thought in the opening and closing of channels that let ions flow in and out of our cells, researchers at Johns Hopkins report. Those channels are critical ...
A mechanism that allows a differentiated cell to reactivate as a stem cell revealed
The study, performed with fruit flies, describes a gene that determines whether a specialized cell conserves the capacity to become a stem cell again. Unveiling the genetic traits that favour the retention ...
