The scientific legacy of Dolly the Sheep
Twenty years ago, British scientists introduced the world to Dolly the sheep, the first mammal to be cloned using nuclear transfer. She only lived for seven ...
Optogenetics: Controlling the brain with light
(04:50) This animation illustrates optogenetics -- a radical new technology for controlling brain activity with light. Ed Boyden (http://mcgovern.mit.edu/principal-investigators/ed-boyden), the co-in...
Cloning Does Not Lead To Early Aging — Relatives Of Dolly Doing Well
Using relatives of Dolly the Sheep, scientists have found that cloned animals do not age faster than their non-cloned peers.
‘Army Of Half-Cloned Mice' Created In China From Artificial Sperm

How far away is human cloning?
Will affluent people start cloning replicas for easy organ donations? Will large corporations begin cloning low cost labor forces? The short answer is no. The longer answer is a little more complicat...
China Human Cloning: Scientific Plant Ready To Crank Out Human Clones
Technology at Boyalife Group is advanced enough to replicate human being, chief executive Xu Xiaochun says. By the year 2020, they hope to have cloned 1 million cattle for China's growing beef demand....
How The Brain Controls Sleep
Sleep is usually considered an all-or-nothing state: The brain is either entirely awake or entirely asleep. However, MIT neuroscientists have discovered a brain circuit that can trigger small regions ...
Sonogenetics: Sound Waves Successfully Used To Control Brain Cells
Scientists say simulating neurons with ultrasound is less invasive than light-based optogenetics. Sound waves have been used to control brain cells for the first time by scientists in California. Dubb...
Revolutionizing A Revolutionary Technology
Optogenetics, a technology that allows scientists to control cells with light, has blown the doors wide open in neuroscience since its debut less than a decade ago. With a new $1-million grant from th...
New Biomarker Identified In Women With Mental Illness
Psychiatric disorders can be difficult to diagnose because clinicians must rely upon interpreted clues, such as a patient’s behaviors and feelings. For the first time, researchers at University of Cal...
Recalling Happier Memories Can Reverse Depression
“Once you identify specific sites in the memory circuit which are not functioning well, or whose boosting will bring a beneficial consequence, there is a possibility of inventing new medical technolog...
Researchers Find “Lost” Memories
Memories that have been “lost” as a result of amnesia can be recalled by activating brain cells with light. In a paper published today in the journal Science, researchers at MIT reveal that they were ...
Scientists Are Closer to Recreating the Woolly Mammoth
Geneticists extracted genetic material from mammoths preserved in Arctic permafrost and used a new DNA scissoring technique, allowing them to make precision edits to elephant DNA and splicing in mammo...
Exploring the universe of the cell; The 2012 GE Healthcare Cell Imaging Competition images
An animated film of the beautiful cell images that competed in the 2012 Cell Imaging Competition; first shown in Times Square New York, 20th April 2013. GE H...
Optogenetics: A wireless, optical router for your brain
It's even weirder than it sounds, too: optogenetics is the manipulation of a cell's functions with light.
Cloning
In biology, cloning is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects or plants reproduce asexually. C...
Flow cytometry
In biotechnology, flow cytometry is a laser-based, biophysical technology employed in cell counting, cell sorting, biomarker detection and protein engineering, by suspending cells in a stream of fluid...
Multicolumn countercurrent solvent gradient purification
Multicolumn Countercurrent Solvent Gradient Purification (MCSGP) is a form of chromatography that is used to separate or purify biomolecules from complex mixtures. It was developed at the Swiss Federa...
Copurification
Copurification in a chemical or biochemical context is the physical separation by chromatography or other purification technique of two or more substances of interest from other contaminating substanc...
Digital holographic microscopy
Digital holographic microscopy (DHM) is digital holography applied to microscopy. Digital holographic microscopy distinguishes itself from other microscopy methods by not recording the projected image...
Evolutionarily significant unit
An Evolutionarily Significant Unit (ESU) (often lowercased where used without abbreviation, as "evolutionarily significant unit") is a population of organisms that is considered distinct for purposes ...
Fluorescence recovery after photobleaching
Fluorescence recovery after photobleaching (FRAP) denotes an optical technique capable of quantifying the two dimensional lateral diffusion of a molecularly thin film containing fluorescently labeled ...
Chromatography
Chromatography (/ˌkroʊməˈtɒɡrəfi/; from Greek χρῶμα chroma "color" and γράφειν graphein "to write") is the collective term for a set of laboratory techniques for the separation of mixtures.The mixture...
