Yale Researchers Discover New Cancer Cell Vulnerability

July 21, 2014

1 Comment

New research from Yale University found that simultaneous inhibition of both telomerase and p21 inhibited tumor growth in mice. Yale School of Medicine and Yale Cancer Center researchers have uncovered a genetic vulnerability of cancer cells that express telomerase — an enzyme that drives their unchecked growth — and showed that telomerase-expressing cells depend upon […]

New Way to Regrow Human Corneas Could Help Overcome a Major Cause of Blindness

July 16, 2014

1 Comment

Harvard-affiliated researchers have discovered a new way to regrow human corneas that could help researchers overcome a major cause of blindness. Researchers have identified a way to enhance regrowth of human corneal tissue to restore vision, using a molecule that acts as a marker for hard-to-find limbal stem cells. This work, a collaboration among the […]

Researchers Reveal That a Doppler Effect Influences Segmentation

July 15, 2014

0 Comments

New research from the Max Planck Institute shows that the rhythm of segmentation is influenced by a Doppler effect that arises from gene expression waves occurring in a shortening embryonic tissue. Many animals exhibit segmental patterns that manifest themselves during development. One classical example is the sequential and rhythmic formation the segmental precursors of the […]

Scientists Coax Human Embryonic Stem Cells to Organize

July 1, 2014

0 Comments

Using geometry, scientists from the Laboratory of Stem Cell Biology and Molecular Embryology at Rockefeller University have coaxed human embryonic stem cells to organize themselves. About seven days after conception, something remarkable occurs in the clump of cells that will eventually become a new human being. They start to specialize. They take on characteristics that […]

Neuroscientists Inhibit Muscle Contractions by Shining Light on Spinal Cord Neurons

June 27, 2014

0 Comments

In a newly published study, MIT neuroscientists show that they can control muscle movement by shining light on spinal cord neurons in mice. For the first time, MIT neuroscientists have shown they can control muscle movement by applying optogenetics — a technique that allows scientists to control neurons’ electrical impulses with light — to the […]

Using an existing FDA-approved drug for rheumatoid arthritis called tofacitinib citrate, a man with alopecia universalis has grown a full head of hair, eyebrows and eyelashes, as well as facial, armpit, and other hair. A man with almost no hair on his body has grown a full head of it after a novel treatment by […]

Scientists Discover New Species of Horned Dinosaur – Mercuriceratops Gemini

June 19, 2014

1 Comment

A newly published study details the discover of a new species of dinosaur named Mercuriceratops Gemini, which was approximately 6 meters long and lived about 77 million years ago during the Late Cretaceous Period. Cleveland, Ohio – Scientists have named a new species of horned dinosaur (ceratopsian) based on fossils collected from Montana in the […]

MOF-Associated Complexes Mediate Genetic Fair Play

June 18, 2014

1 Comment

Scientists from the Max Planck Institute have discovered that the same evolutionary stable MOF protein that regulates X dosis in flies is also involved in compensatory mechanisms in mice. Sexually dimorphic animals are often distinguished by unequal number of the X-chromosomes. While males have only one X chromosome, females have two copies, prompting an evolutionary […]

Visual System of Marine Annelids Provides Insight Into the Evolution of Eyes

June 10, 2014

1 Comment

Scientists of the Max Planck Institute have reconstructed the first neuronal map of the visual system of marine annelids, gaining insight into the evolution of eyes. Larvae of the marine bristle worm Platynereis dumerilii orient themselves using light. Early in their development, these larvae swim towards the light to use surface currents for their dispersal. […]

Scientists Confirm Cellular Basis for Memory by Implanting and Erasing Fear in Rats

June 2, 2014

0 Comments

In a newly published study, scientists at the University of California show the ability to selectively remove a memory and predictably reactivate it by stimulating nerves in the brain at frequencies that are known to weaken and strengthen the connections between nerve cells. Researchers at the University of California, San Diego School of Medicine have […]

Research Shows Diet Beverages Play a Positive Role in Weight Loss Program

May 28, 2014

3 Comments

A new 12-week clinical study is the first prospective, randomized clinical trial to directly compare the effects of water and diet beverages on weight loss within a behavioral weight loss program, revealing that drinking diet beverages helps people lose weight. Aurora, Colorado – A groundbreaking new study released today by the University of Colorado’s Anschutz […]

Scientists Engineer First Living Organism with an Expanded Genetic Alphabet

May 8, 2014

1 Comment

A newly published study details how researchers at The Scripps Research Institute were able to create the first living organism with an expanded genetic alphabet. Scientists at The Scripps Research Institute (TSRI) have engineered a bacterium whose genetic material includes an added pair of DNA “letters,” or bases, not found in nature. The cells of […]
