Beta-catenin molecule is required for tooth root formation
- ScienceDaily
- 13/1/23 20:42
The tooth root, together with the surrounding periodontium, maintains the tooth in the jaw. The root develops after the crown forms, a process called morphogenesis. While the molecular and cellular mechanisms of early tooth development and crown morphogenesis have been extensively studied, little is known about the molecular mechanisms controlling tooth root...

Household chores: Gender equality's final frontier
- ScienceDaily
- 13/1/23 20:42
Working-class couples that buck convention and live together rather than marry take on traditional roles when it comes to housework, according to a new study by a Cornell University sociologist. Cohabiting women do a disproportionate share of the housework, even when the women work and the men don't – and even when the women want to share the housework more...

Through the use of hyperbaric, oxygen-rich chambers, medical researchers have found a way to restore a significant amount of neurological function in brain tissue thought to be chronically damaged by stroke, traumatic injury, and metabolic disorder -- even years after the original...
Space instrument adds big piece to solar corona puzzle
- ScienceDaily
- 13/1/23 20:42
How can the solar atmosphere get hotter, rather than colder, the farther you go from the sun's surface? This mystery has puzzled solar astronomers for decades. A suborbital rocket mission that launched in July 2012 has just provided a major piece of the puzzle.
Synesthesia traced to colors of kids magnetic letters: Learning and memory may play central role
- ScienceDaily
- 13/1/23 20:42
People with color-grapheme synesthesia experience color when viewing written letters or numerals, usually with a particular color evoked by each grapheme (i.e., the letter 'A' evokes the color red). In a new study, researchers present data from 11 color grapheme synesthetes who had startlingly similar color-letter pairings that were traceable to childhood toys containing magnetic colored...

Personal epigenetic 'signatures' found consistent in prostate cancer patients' metastases
- ScienceDaily
- 13/1/23 20:40
In a genome-wide analysis of 13 metastatic prostate cancers, scientists at the Johns Hopkins Kimmel Cancer Center found consistent epigenetic “signatures” across all metastatic tumors in each patient. The discovery of the stable, epigenetic “marks” that sit on the nuclear DNA of cancer cells and alter gene expression, defies a prevailing belief that the marks vary so much within each...
Actual Facebook Graph Searches blog highlights creepy results
When Facebook introduced its new Graph Search feature at a much-hyped event in California last week, tech observers predicted that the results would reach into Facebook users' information in unexpected ways and be, well, just creepy.
A new Tumblr blog called Actual Facebook Graph Searches is proving that prediction true....

Retrovirus in the human genome is active in pluripotent stem cells
- ScienceDaily
- 13/1/23 19:39
A retrovirus called HERV-H, which inserted itself into the human genome millions of years ago, may play an important role in pluripotent stem cells. The discovery, which may help explain how these cells maintain a state of pluripotency and are able to differentiate into many types of cells, could have profound implications for therapies that would use pluripotent stem cells to treat a range of...
Scientists underestimated potential for Tohoku earthquake: Now what?
- ScienceDaily
- 13/1/23 19:39
The massive Tohoku, Japan, earthquake in 2011 and Sumatra-Andaman superquake in 2004 stunned scientists because neither region was thought to be capable of producing a megathrust earthquake with a magnitude exceeding 8.4. Now earthquake scientists are going back to the proverbial drawing board and admitting that existing predictive models looking at maximum earthquake size are no longer...
