In the mind's eye: How the brain makes a whole out of parts

... such work is driven by curiosity about one of the fundamental mysteries: how the brain works. "Our ability to see is one of the great evolutionary accomplishments of the human brain," Connor said. "We still don't know how the visual system accomplishes this marvel of information processing. Such experiments ar...

UC San Diego partners with Venter Institute to build marine microbial genomics cyberinfrastructure

...Along with providing a novel approach to advancing fundamental biological knowledge, analysis of the marine genome data will allow us insight into natural marine products and how they can be applied for pharmacy and medicine," said Wooley, the university's Associate Vice Chancellor for Research. "The new resourc...

Chemical guidance of T cells leads to immunologic memory and long-term immunity

...ese new findings not only provide insight into the fundamental behavior of the immune system, but also suggest that attention needs to be paid to chemokines and chemokine receptor function when designing new vaccine strategies and evaluating whether drugs targeting chemokines might have unanticipated effects on ...

Molecule by molecule, new assay shows real-time gene activity

...ented insights into gene expression and many other fundamental biological processes in living cells." The central...g methods open up new possibilities for addressing fundamental questions about the precise events and factors involved in regulating these essential processes. Thi...

Basic research leads to a novel cancer therapy

...lows down its growth, and shrinks its tissue. This fundamental principle led to the development of SUTENT®, whose active ingredient is Sunitinib. SUTENT® was recently approved for clinical use in the United States, and it is expected to be brought onto the German market this year. When particular growth factors...

Sun protection for plants

Scientists in Sheffield working on the fundamental biological processes of plants could make signific...e, commented, "This demonstrates how research into fundamental biological processes has the potential to have a big impact on people's lives around the world. Many...

Cracking the genetic code for control of gene expression

...rea of research at the moment, likely owing to its fundamental importance to many biological processes. The findings of the Finnish scientists have implications to the study of cancer, evolution, development biology and many other areas of biology. The work revealed a potential mechanism explaining why many diff...

New mechanism for essential genome-wide gene silencing identified

... also, including humans. In an indication of their fundamental nature, critical genetic systems are frequently conserved with few changes in life forms that diverged during evolution millions of years ago. "In our experiments, we saw SUMO binding to histones across the genome, suggesting that if this mechanism ...

High-resolution light microscope reveals the fundamental mechanisms of nerve communication

...in the story of light microscopy, one in which the fundamental questions of biological processes at the nanoscale can potentially be answered with focused light. ...

Research could lead to better drugs and whiter whites

... cleaning and paper manufacturing. "Improving our fundamental knowledge of how enzymes work is important to a wide range of pharmaceutical and industrial fields," said Professor Nigel Scrutton, one of the lead researchers at Manchester. "Enzymes are central to the existence of life because most chemical reacti...

Most human-chimp differences due to gene regulation ?not genes

...hors suggest that altering the regulation of these fundamental and ancient genes may be harmful. In fact, five of the 100 most stable genes have altered expression levels in liver cancer. When they also looked for human genes with significantly higher or lower expression levels, they found 14 genes with increas...

Tandem transcripts team together

...Guigó. "The 'one gene, one protein' rule has been fundamental to molecular biology. However, as we deepen our understanding of the eukaryotic genome, a picture emerges that challenges this paradigm ?not a picture in which the sequences in the genome have distinct functions, but rather one in which the sequence...

Loosen leash on cancer protein 'watchdog,' researchers say

...." Mendrysa said the results were an enlightening fundamental discovery about suppressing hereditary intestinal cancers. But she also said the work raised a number of questions that would need to be answered before the research could translate into human therapy. "These mice were genetically modified at concep...

ASU researchers find link between social behavior, maternal traits in bees

...social life emerged from a solitary lifestyle is a fundamental question," Amdam said. "One theory is that social behavior emerged through new evolutionary inventions. Another is that ancestral solitary phenotypes (characteristics of an organism) were the building blocks of social life, providing a foundation fro...

Evolution of 'irreducible complexity' explained

...on by natural selection. "Our work demonstrates a fundamental error in the current challenges to Darwinism," said Thornton. "New techniques allowed us to see how ancient genes and their functions evolved hundreds of millions of years ago. We found that complexity evolved piecemeal through a process of Molecul...

One big biology question solved

...ian research team has solved one of biology's most fundamental questions ?why males produce sperm and females produce eggs. The finding is a breakthrough that could lead to improved infertility treatment, cancer therapy and pest management. The team, led by Dr Josephine Bowles and Professor Peter Koopman fro...

Taking evolution's temperature: Researchers pinpoint the energy it takes to make a species

...netics Institute. "It tells us something about the fundamental mechanisms that shape biodiversity on the planet." Speciation - when animals or plants actually evolve into a new species - occurs when life forms with a common ancestor undergo substantial genetic change. Using a mathematical model based on the bo...
