New compound could enhance cancer treatments

...Tepe said. Even though this new compound is in the earliest stage of development, this is potentially good news for the millions of Americans diagnosed with cancer every year. The national Centers for Disease Control and Prevention says more than a half-million Americans die of cancer every year, second only ...

A key signaling molecule in osteoarthritis is identified

...her, resulting in pain and loss of movement. "The earliest indication of the disease is a gradual loss of large molecules called proteoglycans from the surface of the joint cartilage," notes Dr. Yefu Li of the Harvard School of Dental Medicine. "This results in a decrease in the mechanical strength of cartil...

Anthropologists find 4.5 million-year-old hominid fossils in Ethiopia

...n Africa to glance into the fossil evidence on the earliest hominids," said IUB paleoanthropologist Sileshi Semaw, who led the research. Semaw and colleagues also report new evidence that suggests the human ancestors lived in close quarters with a menagerie of antelope, rhinos, monkeys, giraffes and hippos i...

Researchers find new genes necessary to make embryo

...d imparted to the egg, ready to be used during the earliest stages after fertilization. They discovered over 150 additional genes required to make an embryo beyond what was previously known, leading them to conclude that many more genes will be found in the future. The researchers estimate that at least 2,600...

The oldest Homo sapiens

... a new study of the 1967 fossil site indicates the earliest known members of our species, Homo sapiens, roamed Africa about 195,000 years ago. "It pushes back the beginning of anatomically modern humans," says geologist Frank Brown, a co-author of the study and dean of the University of Utah's College of ...

Gorilla diet tips -- Have we 'evolved to eat mush'?

... Southern California (USC) hastens to add that our earliest ancestors weren't "buying cartons of eggs from the market," and probably ate many more raw vegetables, fruits and lean meats than today's heavy-protein advocates. Stanford concedes that studying our ancestors' lifestyles may not provide concrete diet...

TGen and Kronos initiate Alzheimer's disease study

Microorganisms at Lost City are living in fluids with alkaline pH that ranges from 9 to...

Most older people with mild cognitive impairment have AD or cerebral vascular disease

Bennett, director of the Rush Alzheimer's Disease Center at Rush University Medical Center and the principal author of the paper. "From a clinical...

Novel ultrafast laser detection of cancer cells also may improve understanding of stem cells

The technique generates a laser beam in single human cells pumped from a flask through tiny microchannels. The beam is altered by what it encounters. These changes, registered by an imaging spectrometer...

Researchers trace evolution to relatively simple genetic changes

It's a simple Mendelian trait that controls formation of hair, teeth and sweat glands. Darwin talked about 'the toothless men...

New findings about protection against pneumococcal disease

...l in every strain and to provide protection at the earliest stage of infection, when pneumococcus is colonizing the nasal passages. The whole-cell vaccine, or a derivative of it, would be a boon for the developing world, because it is inexpensive, covers all pneumococcal strains, and does not require refrig...

In his lab, the avian embryo is an experimental model capable of being modified to allow for the study of specific heart conditions. For example, hypoplastic left heart syndrome is created by simply tying a small suture around the developing at...

'Motherwell's babies' study may yield up clues for adult diseases

... explained: "We now know that growth from the very earliest days in the womb affects health in adulthood, particularly the risks of heart disease, diabetes and osteoporosis. If the mother eats an unbalanced diet this can trigger her body to produce increased amounts of stress hormones, which can then have lon...

Scientists infuse rat spinal cords with brain-derived human stem cells
