Feb. 11, 2016 — Researchers have discovered how cells in the human body build their own ‘railway networks’, throwing light on how diseases such as bowel cancer work. The microtubule tracks are vital for ... read more

Feb. 10, 2016 — DNA is unwound by a type of “pumpjack” mechanism, similar to the way one operates on an oil rig, a team of scientists suggests. This finding is based on new close-up images of the proteins that ... read more

Chemical Cages: New Technique Advances Synthetic Biology

Feb. 10, 2016 — A clever means of localizing and confining enzymes and the substrate molecules they bind with has been presented by researchers, speeding up reactions essential for life ... read more

Expression of a 'Ouija Board' Protein That Can Summon 'Monster' Genes

Feb. 8, 2016 — Biologists have studied Drosophila melanogaster flies to discover a new protein dubbed “Ouija Board,” which plays an important role in the biosynthesis of the steroid hormones necessary for ... read more

Feb. 5, 2016 — The ability to see the direction in which something is moving is vital for survival. Only in this way is it possible to avoid predators, capture prey or, as humans in a modern world, cross a road ... read more

Feb. 5, 2016 — Cells are not uniform spheres; they generally come in a variety of disparate shapes. In the broadest sense, this variation in shapes is known as cell polarity, and it is an essential property for a ... read more

Feb. 5, 2016 — IBS researchers create multiplex Digenome-seq to find errors in CRISPR-Cas9 ... read more

Feb. 4, 2016 — Using a special profiling technique, researchers have determined the mechanism of action of a potent antibiotic, known as tropodithietic acid, leading them to uncover its hidden ability as a ... read more

Feb. 4, 2016 — Researchers have discovered a molecular regulator that allows salmonella bacteria to switch from actively causing disease to lurking in a chronic but asymptomatic state called a ... read more

Hair Thinning by Stem Cell Loss

Feb. 4, 2016 — Why people lose their locks in old age may be related to the aging of hair follicle stem cells, two new studies suggest. Though it is known that mammals that live for longer lifespans lose their ... read more

Feb. 4, 2016 — A process has been uncovered by researchers that uses pressure to deliver chemical probes in a fine-tuned manner into living ... read more

How Roots Grow

Feb. 4, 2016 — In contrast to animals, plants form new organs throughout their entire life, such as roots, branches, flowers and fruits. Researchers wanted to know to what extent plants follow a pre-determined plan ... read more

Feb. 3, 2016 — A new study helps explain how fruit flies get their keen sense of smell. Researchers have identified a set of genetic control switches that interact early in a fly's development to generate ... read more

Biomolecule's Behavior Under Artificial Conditions More Natural Than Expected

Feb. 2, 2016 — Researchers often analyze isolated biomolecules in test tubes, and it is doubtful if the results can be applied to densely-packed cells. A team of researchers monitored the folding of an RNA ... read more

Piecing Together the Cells Elevator-Like Mechanism for Sodium

Feb. 1, 2016 — Researchers have pieced together how sodium is transported into and out of our cells. This could be a potential benefit for the development of novel treatments against some forms of cancer and ... read more

Feb. 1, 2016 — Damaged cells can commit suicide by a process of apoptosis, or programmed cell death. If this mechanism fails to work properly, the cell can become cancerous. Scientists are helping to explain ... read more

The Harbingers of Aging

Jan. 29, 2016 — Researchers have detected age-dependent alterations in metabolism and gene regulation in middle-aged fruitflies, and show that these effects are linked to a reduction in lifespan, suggests a new ... read more

Jan. 29, 2016 — Stem cells have been put into plasters and bandages to help heal wounds for the first time, thanks to a newly developed technique. The method of encasing stem cells in an alginate gel made from ... read more

Jan. 28, 2016 — An estimated 15 million Americans suffer from food allergies, many of them children. These are non-trivial concerns, as food allergy or intolerance can cause symptoms ranging from a harmless skin ... read more

Jan. 28, 2016 — Live mouse progeny can be generated with assisted reproduction using germ cells from males without any Y chromosome genes. In these males, the two Y genes previously demonstrated to be essential for ... read more
