New clues to how sex evolves

... All four of these genes code for different but highly related "zinc-finger" proteins, proteins that usually recognize specific sequences of DNA. Each protein acts to pair and link together one or two specific chromosomes among C. elegans's full set of six. The him and zim genes appear in tandem on a sin...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

...s genes inside the cell. It thus promises to be a highly effective tool when combating the spread of any new strain of virus, as well existing strains. One could give it as a preventive measure without the need to tailor it to a particular flu strain or mutation. This has obvious benefits when dealing wit...

Cities change the songs of birds

...hways, and indeed the birds of urbanized areas are highly similar: The same few species become common everywhere, while the area’s original species variety is lost. The new study, which focuses on an urban “survivor,?provides some insight into the mechanism behind the homogenizing impact of the urban enviro...

Tiny Tampa Bay fish key to evolution of immune system

...tman, of USF's Moffitt Cancer Center - bombarded a highly concentrated, crystallized form of an immune system protein isolated from the fish with X-rays, yielding incredibly high-resolution images of its structure. The lancelet also is known as amphioxus, or by the scientific name Branchiostoma floridae. "...

Researchers link ocean organisms with increased cloud cover and potential climate change

... an amount comparable to what has been measured in highly polluted areas of the globe. If confirmed by field studies, this connection between clouds and biological activity could add a critical new component to global climate models. Many environmental scientists believe that increased cloud cover may be ...

How mammals fuel milk production may have implications for cancer

...gland for lactation is among the most critical and highly conserved in mammals, as provision of nutritional support is essential for the survival of offspring,?said Lewis Chodosh, lead author of the study at the University of Pennsylvania School of Medicine. “Given its remarkable importance, it has been a r...

HIV-1 kills immune cells in the gut that may never bounce back

...g longer, healthier lives since the development of highly active antiretroviral therapy (or HAART) in 1995. In fact, most patients on the drug regimen do so well that, according to blood tests, their immune cells appear to return to pre-HIV levels. But two new studies from Rockefeller University and the Aar...

NYU biologists identify gene that coordinates two cellular processes

...te such connections show that most genes fall into highly interconnected groups called modules. These modules are often enriched for genes that share the same role. In order to determine the functions of genes whose role is unknown, researchers examine genes in the same module whose function has already bee...

A buffet for early human relatives

...ica became drier, while tool-wielding Homo ?with a highly varied diet ?survived and evolved. The new study casts doubt on that theory by showing that Paranthropus, like Homo, also consumed a variety of foods. "Thus, other biological, social or cultural differences may be needed to explain the differ...

Scientists crack genetic secrets of human egg

...roduced. Then the computer analysis began. In a highly sophisticated game of match, every gene in the egg that was found in other tissues was eliminated, so that only unique genes remained. Cibelli said that the team identified 5,331 human genes that are overexpressed in the egg. Of those, 1,430 are my...

The largest obstacle remaining is optimizing the system to dispense the appropriate amount of chlorine dioxide, Morgan said. Enough of the gas must be deployed to kill the pathogens, but too much can cause a ...

Mysterious 'neural noise' actually primes brain for peak performance

"If the structure is the same, that means there must be something fundamentally similar among vision, movement, reasoning, loving--anything that takes place in the human cortex...

Pheromone from mother's milk may rapidly promote learning in newborn mammals

...ropéen des Sciences du Goût. Newborn mammals are highly dependent on their mother's milk for survival, and they typically exhibit a defined sequence of actions when searching for milk. This searching behavior rapidly becomes increasingly directed, showing that mammalian newborns are efficient learners. Pa...
