Tiny carbon nanotube pores make big impact
Scientists have created a new kind of ion channel based on short carbon nanotubes, which can be inserted into synthetic bilayers and live cell membranes to form tiny pores that transport water, protons, small ions and DNA. These carbon nanotube "porins" have significant implications for future health care and bioengineering applications.

Scientists make enzyme that could help explain origins of life
Mimicking natural evolution in a test tube, scientists have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth.

Contamination likely explains 'food genes in blood' claim
Laboratory contaminants likely explain the results of a recent study claiming that complete genes can pass from foods we eat into our blood, according to a molecular biologist who re-examined data from the controversial research paper.

Mechanism that allows differentiated cell to reactivate as a stem cell revealed
A 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 favor the retention of stem cell properties is crucial for regenerative medicine.

Meiotic cell division 'the other way round'
Meiosis is the two-step series of cell divisions that make sexual reproduction and genetic diversity possible. Researchers have now dived into the process of meiosis in specific plant species and revealed that these plants display an inversion of the standard meiotic phases.

Why plants don't get sunburn
Plants rely on sunlight to make their food, but they also need protection from its harmful rays, just like humans do. Recently, scientists discovered a group of molecules in plants that shields them from sun damage. Now scientists report on the mechanics of how these natural plant sunscreens work.

Genome sequencing of the jujube tree completed
The complete, high quality sequencing of the jujube genome has been announced by researchers. Jujube is the most economically important member of the Rhamnaceae family, and the jujube genome is particularly difficult to sequence due the high level of heterozygosity and other complicating factors. It is the first time that a genome in the Rhamnaceae, Buckthorn, family has been sequenced.

Advances in Graves' disease, including a new mouse model
A unique mouse model of Graves' disease, an autoimmune disorder that causes hyperthyroidism, has been developed by scientists, and new research findings may help improve the treatment of Graves' disease, experts report.

Healthy fractions of oats efficiently recovered; leads to development of new food applications
Methods to broaden the use of oats in, for example, snacks and beverages, have been uncovered by a researchers. Fractions with 56% beta-glucan and 73% protein were obtained.

Bee's knees for identifying genetic triggers of novel adult traits
Scientists have long sought to identify the specific DNA changes that can trigger new traits, allowing species to adapt. For development of the embryo, it is usually the master control regions of a gene that dominate, but what about in an adult? Researchers have now found that adults play by a different set of rules, relying on the contributions of novel genes -- called taxonomically restricted genes, TRGs are only found in a given species -- found in honeybees.
