Sequence may contain genes controlling stature and tumor development
Scientists report on Friday in the journal Genome Research that they have successfully cloned and characterized a previously intractable DNA sequence: a 554-kilobase-pair genomic segment near the centromere of the human Y chromosome. This sequence contains eight putatively active genes that could be implicated in sex-associated height differences and gonadal tumor development.
This pericentromeric gap was one of the few holes remaining in the "finished" sequence of the human genome reported last October by the International Human Genome Sequencing Consortium. This "finished" sequence was the culmination of a 13-year effort to elucidate the order and orientation of 2.85 billion basepairs that comprise the human genome. The high-quality sequence spanned more than 99% of the euchromatic (gene-containing) portion of the genome with an accuracy of 99.999%, but despite this accomplishment, substantial sections of chromosomal sequences were still missing.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
