Cell Biology: Active Transporters Are Universally Leaky
May 2, 2013 — Biochemists found that as active transporters in cell membranes undergo conformational changes to allow their main substrates to pass through through, small molecules like water slip through as ... > full story -
Scientists Revolutionize Creation of Genetically Altered Mice to Model Human Disease
May 2, 2013 — Scientists have efficiently created mouse models with multiple gene mutations in a matter of weeks. Because the method does not require embryonic stem cells, the approach also could allow any animal ... > full story -
3-D Simulation Shows How Form of Complex Organs Evolves by Natural Selection
May 2, 2013 — Researchers have developed the first three-dimensional simulation of the evolution of morphology by integrating the mechanisms of genetic regulation that take place during embryo development. The ... > full story -
Use of Laser Light Yields Versatile Manipulation of a Quantum Bit
May 1, 2013 — By using light, researchers have manipulated the quantum state of a single atomic-sized defect in diamond -- the nitrogen-vacancy center -- in a method that not only allows for more unified control ... > full story -
Computer Algorithms Help Find Cancer Connections
May 1, 2013 — Using powerful algorithms developed by computer scientists, medical researchers have assembled the most complete genetic profile yet of acute myeloid leukemia, an aggressive form of blood ... > full storyMore: -
'Dirty Dozen' Invasive Species Threaten UK
May 1, 2013 — Parts of the UK are at greater risk of invasion by non-native aquatic species than previously thought, according to new research. The first to include human factors in models used to predict where ... > full story -
How 'Traffic' in Our Cells Works Both for and Against Us
May 1, 2013 — A mechanism that permits essential substances to enter our cells while at the same time removing from them harmful components also has a “down side.” This negativeaspect prevents vital ... > full story -
How Petals Get Their Shape: Hidden Map Located Within Plant's Growing Buds
April 30, 2013 — Why do rose petals have rounded ends while their leaves are more pointed? Scientists have revealed that the shape of petals is controlled by a hidden map located within the plant's growing ... > full story -
