West Australian fossil find rewrites land mammal evolution

...is little fossil fish, Gogonasus, is therefore the ultimate 'Mother' of all tetrapods." The research findings are published today in the journal Nature. "Gogonasus is the new pivotal fossil for understanding the earliest phase in the transition from sea-going fish to land-dwelling tetrapods - from dinos...

Advance helps explain stem cell behavior

...ttern formation mechanism will be essential to the ultimate use of stem cells in medical research and disease treatment, the scientists said. Ideally, researchers would like to create a "transcriptional network model" that simulates all of the complex and interactive steps in this patterning process, Gross sa...

A natural chemical found in strawberries boosts memory in healthy mice

...very different from that of healthy mice. Thus the ultimate goal is to stop neuronal loss. Nevertheless, memory-enhancing drugs can improve Alzheimer's disease symptoms. The observations that fisetin protects and promotes survival of cultured neurons and boosts memory in healthy mice make it a promising ca...

Nano-devices hold promise for early-stage cancer detection

...etect food- and water-borne pathogens. "The ultimate goal is to develop reliable and inexpensive detection and imaging products that can be used in a doctor’s office or possibly even at home as part of a regular exam," said Steve Hranilovic, assistant professor of electrical and computer engineering at...

Protein 'fingerprint' in spinal fluid could spot Alzheimer's disease

...use to diagnose illness and guide treatment is the ultimate goal. But the finding has important implications for current Alzheimer's research, as well. "You might have a promising treatment for the disease, but how can you know for sure that it's impacting on the underlying pathology, rather than just easi...

Researchers develop technologies to devour food pathogens

...ely believe it could help save lives, which is our ultimate goal." Industry has shown interest in Bhunia's technology, as well as the chlorine dioxide work done by Linton and the project's co-leader, Mark Morgan, a professor of food science. "We are currently working on an industrial tunnel system to appl...

Math model predicts cancer behavior

...ironment around tumor cells determines the tumor's ultimate cellular makeup and invasive potential. The investigators have focused on the events of invasion and metastasis (movement of a tumor to distant sites), Quaranta said, because these events mark "the critical transition of a tumor that in the end wil...

Newly discovered fish named after New York aquarium biologist

...servation Society's New York Aquarium received the ultimate honor recently, when a freshwater fish discovered on the African island nation of Madagascar was named after him. Dr. Paul Loiselle, who has dedicated much of his career safeguarding Madagascar's little- known freshwater fishes, received the honor f...

Liposuctioned fat stem cells to repair bodies

...ecular tags could allow scientists to pull off the ultimate trick of taking a patient’s own fat cells and using them for therapy, Collas told researchers gathered at the EuroSTELLS Workshop ‘Exploring Chromatin in Stem Cells?held on January 23-24, in Montpellier, France. "Fat tissue is an underappreciated so...

Walking molecule now carries packages

...ing machines at the scale of single molecules will ultimate be the most efficient way to build objects or to deliver material. "It resembles the way nature does it: the molecule carrier transports carbon dioxide across a surface," he said. "In the human body, the molecule hemoglobin carries oxygen from and ...

Stanford scientists make major breakthrough in regenerative medicine

...bodies against injury, deformity, and disease. The ultimate medical treatment would be to change an abnormal organ or tissue back to its vibrant, normal state," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "This study is a landmark in regenerative medicine; the Stanford group has accompl...

Tiny clue reveals new path toward heart disease

...revent the disease, the researchers said. "The ultimate goal is to determine who will develop cardiovascular disease," said lead study investigator Liyong Wang, Ph.D., a research associate at the Duke Center for Human Genetics. "Our discovery could lead to a clinical tool for assessing a person's risk of ...

Penn researchers replace organ in adult mice using 'single-parent' stem cells

...he routine function of adult tissue, which was the ultimate goal for deriving these stem cells." To study uniparental stem cells and the possible effects of genomic imprinting, McLaughlin's team created an experiment in which they would attempt to reconstitute the hematopoietic, or blood-producing, stem ce...

Chemical switch triggers critical cell activities

...lled E3, which then helps E2 hand NEDD8 off to the ultimate target molecule at the end of the race. In the cell, this NEDD8 relay race triggers a number of biochemical reactions, one of which takes the brakes off cell division, allowing cells to multiply, according to the researchers. These thioester bonds ar...

Antivirals effectively curb influenza virus

"The ultimate resolution of these issues must await considerations of larger samples of European early modern humans and chronologically intervening specimens. But this fossil is a major addition to the growing body of fossil, genetic and archaeological evidence ...

Bats prey on nocturnally migrating songbirds

...dence. Indeed, presence of feathers in diet was no ultimate demonstration of a bird-based diet, although indicative. New innovative approaches were thus necessary for proving the case. But how to study the foraging habits of an elusive predator that chases its favourite prey several hundreds if not thousands ...

Researchers create artificial enzyme that mimics the body's internal engine

The protein cytochrome c oxidase (CcO) is the ultimate enzyme responsible for all aerobic life on Earth, from bacteria to people. It is also a crucial component of the cellular machinery that generates energy in our body. With such impressive credentials, you might expect that scientists would have a cle...
