Cities change the songs of birds

...in adapting to urban life, researchers have gained insight into the kinds of environmental pressures that inf...which focuses on an urban “survivor,?provides some insight into the mechanism behind the homogenizing impact of the urban environment. The capacity of great ti...

A valuable fly for research into disease

...ack to the last century and have provided valuable insight into the fundamental principles of biology and genetics. Only in recent years, however, and thanks in large part to the discovery of the high degree of homology between the genetic make-up of flies and vertebrates, has Drosophila emerged as one of th...

How mammals fuel milk production may have implications for cancer

...l Cell Metabolism, published by Cell Press, offers insight into the manner in which the mammary glands of mammals meet the incredible metabolic demands of milk production. As the normal pathways of breast development undoubtedly affect breast cancer, the findings may have therapeutic implications, the resear...

The power of one: A simpler, cheaper method for cell fusion

...ell research, where it affords researchers greater insight into how genes guide protein synthesis. It also may be used to create large quantities of different disease-specific antibodies and has helped scientists clone mammals. The current technique for electrofusion requires a pricey electrical pulse-gen...

Learning during sleep?

...nvestigations which promises previously impossible insight into the largely under-researched field of information processing in the brain (Nature Neuroscience, November 2006). The question of how the brain stores or discards memories still remains largely unexplained. Many brain researchers regard the conso...

PET imaging shows young smokers quick benefit of quitting

... organ or tissue function?will continue to provide insight into coronary risk analysis and risk management (such as smoking cessation and lowering one's cholesterol)," he added. In the Hokkaido University study, researchers examined the effects of smoking cessation on coronary endothelial dysfunction in 1...

Environmental toxins may cause body's defenses to worsen lung disease

... the cells react to these stimuli, we hope to gain insight into what triggers and mediates the immune system response," Borchers says. This will help scientists determine which lymphocytes are important for regulating damage in the lungs, so they can develop ways to "tweak" the immune system and prevent th...

Mysterious 'neural noise' actually primes brain for peak performance

...r you. Similarly, intuition may be less a burst of insight than a rough consensus among your neurons. Pouget and his team are now expanding their findings across the entire cortex, because every part of our highly developed cortex displays a similar underlying Bayes-optimal structure. "If the structure i...

Sea urchin genome suprisingly similar to man and may hold key to cures

...ding ancestral sea urchin genes may give important insight on their function in humans, in the same way the s...ine creatures. Those cells also might provide some insight into human immunity to diseases. Calestani, who teaches genetics at UCF, worked with Davidson at ...

Detailed 3-D image catches a key regulator of neural stem cell differentiation in action

...Having a specific inhibitor would give us a lot of insight into the development of the fetal nervous system and would allow us to chemically push embryonic stem cells to acquire a neuronal fate in an informed way," adds Pfaff. Scp1 belongs to group of proteins called small carboxyl-terminal phosphatases (...

Study illuminates how the plague bacteria causes disease

...stood mechanism. The findings offer important new insight into the factors that lend Yersinia their ability to spawn disease, the researchers said. The results might also contribute to new strategies for fighting the bug. "Yersinia injects several virulence factors into its host," said C. Erec Stebbins of ...

University of Iowa scientists explore function of 'junk DNA'

...ning how these microRNAs are expressed may give us insight into these critical biological processes," said Borchert, who is lead author of the study. "Up to now it's been understood that one enzyme controls their expression, and we now show that in some cases it's a completely different one." Genes that c...

Seals protect brain, conserve oxygen by turning off shivering response on icy dives

...Circle in Tromsø, Norway. The research provides insight into how seals allow their bodies to cool (become hypothermic) during a dive, presumably to better cope with a lack of oxygen (hypoxia). Research into hypothermia and hypoxia is important because they are problems that affect people under a variety o...

Evolution and the workaround

... cells adapt to internal perturbations could offer insight into how pathogens and cancer cells mutate to evade the body’s defenses and resist treatment with drugs. The Stowers researchers used the benign budding yeast Saccharomyces cerevisiae as their model organism and deleted a key cell division gene ...

An artificial cornea is in sight, thanks to biomimetic hydrogels

...jects, worked with potential sponsors and provided insight into polymer physics. Nabeel Farooqui in Ophthalmology developed histology procedures. Won-Gun Koh, a former postdoctoral fellow in Chemical Engineering, first synthesized the polymer that Myung ultimately developed. Qi Liao, a graduate student in Ch...

Worms produce surprise insight into human fever

...alth of data on innate immunity plus a surprising insight into another classic metazoan response to infection fever. The first pathway was p38 MAPK/CED-3, which is also required for the activation of programmed cell death under certain stresses. The other was a heat shock transcription factor-1 (HSF-...

Neural stem cells lend the brain a surprising capacity for self-repair

...e journal Cell, published by Cell Press. The novel insight into the brain's natural ability to heal might ultimately have clinical implications for the treatment of brain damage, according to the researchers. The researchers found that mice whose brains were severely damaged by loss of the genes "Numb" and ...

Fish species plays surprise role in aiding coral reef recovery

...after overfishing. In doing so, the study provides insight into the poorly understood—and potentially complex—forces that influence the state of coral reefs under ecological stress. The work appears in the December 19th issue of the journal Current Biology, published by Cell Press, and is reported by David B...

Critical hearing gene helps send auditory messages to brain

History-hunting geneticists can still follow familiar trail

...larities and differences of mtDNA, scientists gain insight about the size of groups and how they moved around the world. "When you look at ancient migration, you're always asking the question, 'How big was the population, how many were there?'" said Michael Miyamoto, a professor and associate chairman of ...
