...f thousands of years ago," although recent studies suggested Homo sapiens might have had contact with Homo erectus in Asia 50,000 years ago. Reed says: "Not only did modern humans live contemporaneously with close cousins such as Neanderthals, but also with more archaic hominids such as Homo erectus,...

Use of aspirin or other NSAIDs increases survival

...re and radiation dose. Laboratory studies have suggested that by inhibiting the COX-1 and COX-2 enzymes, NSAIDs may enhance programmed cell death (apoptosis) and inhibit the development of blood vessels (angiogenesis) that feed a tumor. The Fox Chase researchers concluded that inhibiting these COX enzymes...

"The only other human fecal source near the wells is sanitary sewer lines," Borchardt said. "Sanitary sewers can leak and it is possible the leakage ...

Is more better: Counting birds may only tell part of the story

... by Beatrice Van Horn in 1983, where she initially suggested that density could be a misleading indicator of habitat quality if it was disconnected from reproductive success or survival. After reviewing multiple studies, Bock and Jones found that counts are generally good indicators, but that there are some...

The staircase parallels the outside exterior wall, thereby enabling a balcony above and a first-floor exit in a large semicircularshaped expanse of glass below. In order to keep the new wing that extends ...

Acoustics meeting in San Diego

...est. Last year in the journal Nature, researchers suggested that some version of decompression sickness might be involved. Meanwhile, recent studies show that marine mammals might commonly carry "supersaturated" levels of nitrogen, in which a higher-than-normal amount of nitrogen gas is dissolved in their bo...

Mitochondria findings may help beat wide range of disease

...etheless able to fuse -- surprised them because it suggested that mitochondria contain within themselves all the proteins necessary for fusion. This stands in stark contrast to the process of single-membrane fusion, which requires many additional cellular proteins to carry out this important function. "We obse...

Channel protein converts vibrations to electrical signal

...nt discovery of the tip-link protein, cadherin 23, suggested that their structure is too rigid for this role. "Part of the TRPA1 molecule is a long chain of ankryin repeats, and we think that the ankryin repeats actually form the elastic element that had been defined biophysically," Corey said. He plans furthe...

Perceptual decision-making hub pinpointed in human brain

...4 Nature. Although earlier studies in monkeys had suggested that such a decision-making hub exists, its location in the human brain was not previously known. The researchers took advantage of the fact that it takes the brain longer to figure out what it's looking at when an image is very blurred or obscur...

Scientists explain how morphogens work

...nd transcytosis. In extracellular diffusion, it is suggested that morphogens move across cells by traveling across the surface of cells. Alternatively, the transcytosis model proposes that cells transfer morphogen molecules through endocytosis, which is the incorporation of substances into a cell by pinching o...

Researchers redrawing the Tree of Life

...classification of others. In the past, most people suggested magnolias or buttercups were some of the earliest evolving flowering plants, or the base of the flowering plants tree. Now, Hilu said, a small shrub from New Caledonia called an Amborella forms the base, with water lilies coming directly after that. ...

New version of tumor-suppressor linked to progression of childhood cancer

...d prostate cancers. However, previous studies have suggested that TrkA acts as a tumor-suppressor in NB. Dr. Andrew R. Mackay and colleagues from the University of L'Aquila in Italy found a previously undiscovered variant of TrkA, called TrkIII, which exhibits oncogenic properties in human NB cells. TrkIII lev...

Biomedical engineers at case develop first sliver-sized sensor to monitor glucose levels

"We also thought that color can be seen better from the outside if the sliver is not too deep, and if it gets distorted by the skin this can be corrected ...
