Connie K. Ho for redOrbit.com With food items like cheese and wine, it´s thought that a longer time of preparation will give it a better taste. This idea of age affecting quality was highlighted in a new study by Northwestern University scientists. A recent study by researchers at Northwestern University found that people whose fathers and grandfathers waited until they were older to have children tended to have a higher amount of resources for the body to repair cells and tissues....

Naphthalene is best known as the key ingredient in mothballs According to a new study, children exposed to high levels of the common air pollutant naphthalene are at increased risk for chromosomal aberrations (CAs), which have been previously associated with cancer. These include chromosomal translocations, a potentially more harmful and long-lasting subtype of CAs. Researchers from the Columbia Center for Children's Environmental Health (CCCEH) at the Mailman School of Public Health,...

Does Polyploidy Play A Role In The Italian Endemic Flora?

Besides the obvious differences between plants and animals, subtle ones lie concealed within the cell, even within the nucleus. In both plant and animal cells, the nucleus contains DNA, which condenses into chromosomes during cell division. Chromosomes can be counted at that stage, revealing the chromosome number for each species. Here comes a difference: while the chromosome number spans a relatively short range across animal species (2-296: 46 in man), some plant species have over 1000...

They have identified new functions of cohesin SA1 that are relevant for cancer and CdLS Cohesin is a ring-shaped protein complex involved in the spatial organization of the genome and in mitotic chromosome structure. Vertebrate somatic cells have two versions of cohesin that contain either SA1 or SA2, but their functional specificity has been largely ignored. Researchers of the Spanish National Cancer Research Centre (CNIO) under the direction of Ana Losada have identified new functions of...

(Ivanhoe Newswire) -- In today's society, kids already act and look older than they are. Recent research has proved that the DNA of 10-year-olds who have experienced violence at a young age are found to show wear and tear normally associated with aging. "This is the first time it has been shown that our telomeres can shorten at a faster rate even at a really young age, while kids are still experiencing stress," Idan Shalev, a post-doctoral researcher in psychology and neuroscience at the...

Children Age Faster When Exposed To Violence And Bullying

Researchers have found that violence in the lives of children can cause changes in their DNA equivalent to seven to 10 years of premature aging. Scientists measured this cellular aging by studying the ends of children´s chromosomes, called telomeres. Telomeres are DNA sequences that act like the plastic tips on shoelaces, which prevent the DNA in chromosomes from unraveling. Each time a cell divides, the telomeres become shorter until a cell dies when it can´t divide anymore,...

Children who have experienced violence might really be older than their years. The DNA of 10-year-olds who experienced violence in their young lives has been found to show wear and tear normally associated with aging, a Duke University study has found. "This is the first time it has been shown that our telomeres can shorten at a faster rate even at a really young age, while kids are still experiencing stress," said Idan Shalev, a post-doctoral researcher in psychology and neuroscience at...

Predicting Risk Of Heart Attacks With Chromosome Length
2012-03-26 12:19:20

Scientists in Boston, Massachusetts have discovered a chromosomal link to heart cancer by studying the length of proteins in a chromosome. The key factor at play in this research are telemores, or DNA protein complexes. These protein complexes can be thought of as “caps”, protecting chromosomes from deteriorating and melding with other chromosomes. As time goes on and chromosomes continue to replicate and cells divide, these telemores will naturally shorten. How much these...
