Prehistoric mystery organism verified as giant fungus

..., any given type of plant will typically contain a similar ratio of carbon-12 to carbon-13 as another plant of the same type. "But if you’re an animal, you will look like whatever you eat," Boyce said. And Prototaxites displayed a much wider variation in its ratio of carbon-12 to carbon-13 content than would...

Stanford scientists make major breakthrough in regenerative medicine

Gene hunters close in on Lou Gehrig’s disease

...the works that will replicate the research using a similar number of patients and controls. Traynor, who has a joint affiliation with the National Institute of Mental Health in Bethesda, Md., collaborated in this study with lead author Jennifer Schymick and fellow researcher John Hardy, Ph.D., both of the La...

Cells use 'noise' to make cell-fate decisions

...s havoc on electronic devices. But within cells, a similar kind of biochemical "noise" is beneficial, helping cells transform from one state to another, according to a new study led by a UT Southwestern Medical Center researcher. Dr. Gürol Süel, assistant professor of pharmacology, said his research and th...

Microfluidic chip helps solve cellular mating puzzle

...ng behavior. Human cells ‘talk?to one another in a similar way, and it’s important to understand this process." Yeast cells mate by sending out pheromone designed to catch the attention of nearby cells of the opposite mating type. When a prospective partner picks up this "scent," it alters its shape and s...

Anti-herpes treatment reduces HIV levels in women infected with both viruses

...ical and sub-clinical manifestations of HSV with a similar efficacy on HIV as HSV suppressive therapy, would represent a long-lasting form of HIV prevention. The development and evaluation of an HSV vaccine should rank high on the international research agenda.' Gareth Thomas, UK Minister for International...

Turtles are loyal in feeding as well as in breeding

... able to return to exactly the same sites via very similar routes. We do not yet know why they return to the same sites, but these findings give us a much better picture of the behaviour of adult turtles at sea, where they spend the majority of their life cycle.' Scientists have long known that marine tur...

Lower carbon dioxide emissions from coal-fueled power plants possible with technology development

Rochelle will share one third of the TXU funds with other colleagues in the university’s College of Engineering and in the Jackson School of Geosciences. These colleagues ...

Lizards 'shout' against a noisy background

Liposuctioned fat stem cells to repair bodies

...in humans. Therapies using bone marrow stem cells, similar to fat stem cells, have achieved some successes, but the focus is shifting to fat, since the tissue is easier to access and extract than the bone marrow. That fat-based methods work is not surprising, perhaps, because adipose tissue is closely relate...

Ultrathin films deliver DNA as possible gene therapy tool

...edical procedures to open blocked arteries. While similar in concept to currently available drug-coated stents, Lynn's devices could offer additional advantages. For example, Lynn hopes to deliver genes that could prevent the growth of smooth muscle tissue into the stents, a process which can re-clog arter...

'Terror bird' arrived in North America before land bridge, study finds

"It was previously thought that Titanis immigrated to Texas across the Panamanian land bridge that formed about 3 million years ago connecting North and South America," said MacFadden, a curator of vertebrate paleo...

New culture method for hepatitis C virus uses primary hepatocytes and patient serum

...bursts of virus produced every 10-14 days. This is similar to what has been reported during clinical HCV infection, possibly due to the host's natural defenses. Interestingly, cultured hepatocytes responded to viral replication by displaying signs of distress and cell death and by expressing interferon-beta...
