High-powered microscopes reveal workings of the cell -- results could impact treatment of Down syndrome, lissencephaly (a brain formation disorder) or cancer Scientists using high-powered microscopes have made a stunning observation of the architecture within a cell — and identified for the first time how the architecture changes during the formation of gametes, also known as sex cells, in order to successfully complete the process. The findings by the international team led by...

A new approach to investigating hard-to-find chromosomal abnormalities has identified 33 genes associated with autism and related disorders, 22 for the first time. Several of these genes also appear to be altered in different ways in individuals with psychiatric disorders such as schizophrenia, symptoms of which may begin in adolescence or adulthood. "By sequencing the genomes of a group of children with neurodevelopmental abnormalities, including autism, who were also known to have...

Sex, Tools And Chromosomes

Researchers at the University of California, Davis have discovered a key tool that helps sperm and eggs develop exactly 23 chromosomes each. The work, which could lead to insights into fertility, spontaneous miscarriages, cancer and developmental disorders, is published April 13 in the journal Cell. Healthy humans have 46 chromosomes, 23 from the sperm and 23 from the egg. An embryo with the wrong number of chromosomes is usually miscarried, or develops disorders such as Down's syndrome,...

Findings provide tools for better understanding of the human genome Chromosomes are strands of DNA that contain the blueprint of all living organisms. Humans have 23 pairs of chromosomes that instruct how genes are regulated during development of the human body. While scientists have developed an understanding of the one-dimensional structure of DNA, until today, little was known about how different parts of DNA are folded next to each other inside the nucleus. Using a powerful DNA...

The search for a solid answer on whether DNA can be reprogrammed or influenced through frequencies and words may have been answered based on a recent study by noted Russian biophysicist and molecular biologist Pjotr Garjajev and supporting article posted at BeWellBuzz.com. Las Vegas, NV (PRWEB) February 23, 2012 The search for a solid answer on whether DNA can be reprogrammed or influenced through frequencies and words may have been answered based on a recent study by noted Russian...

New Study Offers Evidence Against 'Rotting Y' Chromosome Theory

Males of the world, fear not -- researchers have determined that the chromosome which determines maleness is not shrinking after all, and concerns that the gender could be headed for extinction are apparently unfounded. The study, which was led by Jennifer Hughes and David Page of the Whitehead Institute for Biomedical Research and the MIT Department of Biology, have compared the genes of the human Y chromosome to those of chimpanzees and rhesus macaques, according to Guardian Science...

To solve a mystery, sometimes a great detective need only study the clues in front of him. Like Agatha Christie's Hercule Poirot and Arthur Conan Doyle's Sherlock Holmes, Tomomi Kiyomitsu used his keen powers of observation to solve a puzzle that had mystified researchers for years: in a cell undergoing mitotic cell division, what internal signals cause its chromosomes to align on a center axis? "People have been looking at these proteins and players in mitosis for decades, and no one ever...
