"A new genetic biomarker that indicates an increased risk for developing breast cancer can be found in an individual's "junk" (non-coding) DNA, according to a new study featuring work from researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech and their colleagues."

An curious contagious cancer, found in dogs, wolves and coyotes, can repair its own genetic mutations by adopting genes from its host animal, according to a new study in the journal Science.

Dogs Decoded reveals the science behind the remarkable bond between humans and their dogs and investigates new discoveries in genetics that are illuminating the origin of dogs - with surprising implications for the evolution of human culture. Other research is proving what dog lovers have suspected all along: Dogs have an uncanny ability to read and respond to human emotions. Humans, in turn, respond to dogs with the same hormone responsible for bonding mothers to their babies. How did this incredible relationship between humans and dogs come to be? And how can dogs, so closely related to fearsome wild wolves, behave so differently?

ScienceDaily (May 4, 2011) - Using simple robots to simulate genetic evolution over hundreds of generations, Swiss scientists provide quantitative proof of kin selection and shed light on one of the most enduring puzzles in biology: Why do most social animals, including humans, go out of their way to help each other? In the online, open access journal PLoS Biology, EPFL robotics professor Dario Floreano teams up with University of Lausanne biologist Laurent Keller to weigh in on the oft-debated question of the evolution of altruism genes.

A new algorithm may give quantum computers a new, practical job: quickly solving monster linear equations. Such problems are at the heart of complex processes such as image and video processing, genetic analyses and even Internet traffic control.

Genomic DNA was isolated from Staphylococcus aureus samples provided by Mahendra Trivedi and sub cultured samples provided by Bangalore Genei using Ultrapure Genomic DNA prep Kit.

The objective of the project by Trivedi Science is to Genotype five samples (CONTROL Versus TREATED) of the same line with five primers on Enterobacter aerogenes ATCC 13048.

The major question of how to increase crop yield dramatically, has been solved by the new upcoming biotechnological methods, there are various threats posed by these methods when it comes to genetically modified plants.

Trivedi Science - Solation of genomic DNA from Klebsiella pneumonia (ATCC 15380) samples, generating RAPD-Fingerprinting profiles showing Polymorphic bands with five RAPD primers

Unique science of Mahendra Trivedi. He has given extremely, amazing results in agriculture, materials science, plants genetics and biotechnology.

Organic cotton production is the process of growing cotton by using methods and materials that have a low impact on the environment. The seeds used to grow cotton are untreated and are not modified genetically.

Many journals have published without hesitation the findings of our research in Materials Science, agriculture, genetics and Microbiology etc.

Waste paper-enhancing enzyme: Waste paper-enhancing enzyme is a biological protein that is genetically modified and deeply fermented.

Common beans (Phaseolus vulgaris L.) are the most important legume staple food in Kenya coming second to maize. In Central Highlands of Kenya, the 0.4-0.5ton ha-1 output is below the genetic yield potential of 1.5-2ton ha-1 partly due pests and diseases. Plant parasitic nematodes (PPN) have been reported to cause yield losses of up to 60% on beans. Though bean production is important in the Central highlands of Kenya, information on PPN associated with the beans in the region is lacking. This study was therefore undertaken to establish the diversity of PPN associated with common beans and to assess the root knot nematode damage on beans in the region. The study covered 50 farms (32 in Kirinyaga and 18 in Embu Counties) distributed in eight localities namely Kibirigwi (L1), Makutano (L2), Kagio (L3), Mwea (L4) and Kutus (L5) in Kirinyaga County and Nembure (L6), Manyatta (L7) and Runyenjes (L8) in Embu County and covering three Agro Ecological Zones (AEZs); UM2 (L1, L2, L3 & L4), UM3 (L5, L7 & L8) and UM4 (L6) AEZs. Manyatta (L7) and Nembure (L6), had the highest and second highest gall indices, respectively, while Kibirigwi (L1), Makutano (L2) and Mwea (L4) had some of the lowest gall indices. The most common PPN in bean roots were Meloidogyne spp. Pratylenchus spp. and Scutellonema spp. with a frequency of 94.38%, 78.25% and 59.13%, respectively. This further confirm the importance of these nematodes in bean production systems. Upper Midland 3 (UM3) AEZs and UM4 had higher nematode population densities and diversity than UM2. Disease severity and nematode composition and distribution were notably low in the irrigated areas Kibirigwi, Kagio and Mwea compared to rain-fed areas such as Makutano, Nembure and Manyatta.

Patricia Chocano-Bedoya (University of Massachusetts, Amherst) et al. American Journal of Epidemiology, doi: 10.1093/aje/kws363 "Einen Haken hat die segensreiche Wirkung von Eisen und Zink allerdings: Eine signifikante Wirkung trat nur dann auf, wenn die Frauen mehr davon eingenommen hatten, als es der eigentlich empfohlenen Tagesdosis entspricht. "Weitere Studien sind deshalb dringend nötig, um festzustellen, ob die Vorteile einer höheren Eisen- und Zinkgabe die Risiken aufwiegen", betonen die Forscherinnen. Ebenfalls weiter untersucht werden muss ihrer Ansicht nach, warum ein weiteres Mineral, Kalium, PMS sogar zu fördern scheint. Selbst Frauen, die über längere Zeit knapp weniger als die empfohlene Tagesdosis von 4.700 Milligramm Kalium aufgenommen hatten, entwickelten häufiger Beschwerden als Teilnehmerinnen mit sehr niedrigen Kaliumwerten. Warum das so ist, müsse aber noch geklärt werden, sagen Chocano-Bedoya und ihre Kolleginnen."

"Insulin und Fettstoffwechsel: Insulin führt ja nicht nur den Muskelzellen die Glucose zu, sondern auch den Fettzellen. Von denen wird die Glucose zu Speicherfett "umgebaut" mit dem Ergebnis, daß die Fettzelle wächst. Gleichzeitig hemmt Insulin die Lipolyse, d.h. vorhandenes Körperfett wird weniger gut abgespalten und es wird schwieriger, sein Körpergewicht zu reduzieren. Andererseits behindern die bei der Fettspaltung entstehenden und durch die Nahrung aufgenommenen freien Fettsäuren den Insulinrezeptor, so daß es zu einer Insulinresistenz kommen kann (weil das im Blut zirkulierende Insulin dann nicht mehr dort andocken kann). Man spricht dann auch von einer Fettsäureresistenz. Insulin ist ein anaboles (=aufbauendes) Hormon, weswegen es auch in der Tiermast eingesetzt wird. (Stichwort: Masthormon). Nach dem zweiten Weltkrieg wurde unterernährten Stadtkindern Insulin in geringen Dosen verabreicht, damit sie leichter an Gewicht zulegen konnten."
