... shift in the way we think of provider continuity, arguing the need to expand the meaning to include the patient and informal caregivers. Currently, provider continuity is defined by visits over time to the same clinician. Buetow points out that many patients and informal caregivers are co-providers of healt...

Endurance running may be key to evolution of human body form

... most transforming events in human history. We are arguing the emergence of humans is tied to the evolution of running." This work started 13 years ago when Lieberman and Bramble began questioning why pigs are such poor runners. Bramble noted that unlike horses, dogs, cheetahs and other good runners, pigs...

How running made us human

... most transforming events in human history. We are arguing the emergence of humans is tied to the evolution of running." That conclusion is contrary to the conventional theory that running simply was a byproduct of the human ability to walk. Bipedalism the ability to walk upright on two legs evolved in t...

University of Chicago researchers discovered that humans are a 'privileged' evolutionary lineage

...e involved in controlling brain size and behavior, arguing that genes that affect brain size and behavior are preferential targets of selection during human evolution. Lahn and his colleagues now are focusing on these outlier genes, which may reveal more about how the human brain became bigger and better. Fo...

Component of plastic stimulates growth of certain prostate cancer cells

... under intense debate for several years, with some arguing that exposure to the chemical among humans is safe, with others contending that it may promote the growth of human tumor cells and alter the growth and development of animals. Also participating in the study were Yelena Wetherill, Ph.D., Nicola Fish...

Ecologists see the primeval wood for the trees

...iew of ancient woodland as closed canopy forest by arguing that ancient woodlands would have resembled modern parkland because of the action of large grazing animals such as aurochs (primitive cattle), tarpan (wild horses), deer and wild boar. There are no stands of primeval virgin woodland in Europe today,...

Physics team puts new twist on spin hall effect

...ical firestorm, resulting in more than 50 articles arguing for and against the possibility. As the heated debate raged on, Wunderlich and Kaestner developed a new type of device to measure magnetization at each side of a high-mobility, ultra-thin conducting layer embedded within a semiconductor chip using bu...

Family trees of ancient bacteria reveal evolutionary moves

...nts for transitions that triggered change, but I'm arguing that a lot of these things could be evolutionary." Blank presented her research at the 2004 annual meeting of the Geological Society of America, held, Nov. 7-10 in Denver. Blank's finding that Cyanobacteria emerged first in fresh water lakes or stre...

Scientists will discuss remarkable advances in whale research at the annual meeting of AAAS

... for scientific research. The Japanese government, arguing that minke whales are relatively abundant, allows the slaughtered giants to be sold as food. In the early 1990s, conservationists began to suspect that threatened and endangered species also were being commercially exploited. To find out, Palumbi dec...

Ancient olfaction protein is shared by many bugs, offering new pest control target

... the gene, the flies' sense of smell was restored, arguing not only that the gene's sequence has been conserved over 250 million years of evolution but that the gene's function in olfaction has also been conserved. Future designs of pesticides and disease-controlling insect repellents may be able to utilize ...

Fat may affect electrical impulses in brain, heart

...t site is found in several other proteins as well, arguing for an evolutionarily conserved function for this amino acid sequence. Most strikingly, five of six amino acids adjacent to the attachment site matched a site where palmitate is known to attach to CD36, an abundant protein vital for moving fatty mol...

New discovery blurs distinction between human cells and those of bacteria

...tween eukaryotic cells and those of prokaryotes by arguing that bacterial cells are more complex than one would imagine, and that many of them have evolved sophisticated mechanisms," Yeates said. While microcompartments have been directly observed in only a few organisms, "surely there will be many more," Ye...

Warming most evident at high latitudes, but greatest impact will be in tropics

...re really being hammered by climate change. We are arguing that this might not be true," said Joshua Tewksbury, a UW assistant professor of biology. "To predict the impact of climate change, we need to know the amount of change and how organisms are able to tolerate that change. Previous research has focused...

Research suggests fitness of Florida panthers improved by limited breeding with Texas animals

...he said was dismissed from his government post for arguing that developers should not be given permits to clear areas where the endangered species has not been seen before. "Our results support his contention that the panther is a generalist. You certainly don't want to give up areas to developers by assumin...

Species take care of each other in ecological communities

...ources. The research team modified this theory by arguing that the birth rate and mortality rate are not identical across species, but there is a "density-dependent" probability of birth and death. The more abundant species have lower birth rates and higher mortality rates. "The consequence is that when a s...

When seeing is misleading: Clutter leads to high-confidence errors

"It's a way to present the state-of-the-art in preeclampsia research," said Dr. Roberts, professor and vice chairman of research in the department of obstetrics, gynecology and reproductive sciences at the Univer...

Mankind benefits from eating less meat

...o 233 billion kilos per year. The researchers are arguing for a "protein transition". We must eat less meat and partly replace our protein requirements with so-called Novel Protein Foods (NPFs). These NPFs are based on plant proteins that are derived from, for example, peas or soya. While we don't all have ...
