It's one thing to recognize your childhood home when you see it in a photograph and quite another to accurately describe or draw a picture of it based on your recollection of how it looked. A new report published online on April 28 in Current Biology, a Cell Press publication, offers some of the first clear evidence that monkeys, like humans, have the capacity for both forms of memory. The researchers found that rhesus monkeys can flexibly recall extremely simple shapes from memory, as evidenced by their ability to reproduce those shapes on a computer touch screen. The ...

Our own social status influences the way our brains respond to others of higher or lower rank, according to a new study reported online on April 28 in Current Biology, a Cell Press publication. People of higher subjective socioeconomic status show greater brain activity in response to other high-ranked individuals, while those with lower status have a greater response to other low-status individuals. These differences register in a key component of the brain's value system, a region known as the ventral striatum. "The way we interact with and behave around other people ...

Box jellyfish may seem like rather simple creatures, but in fact their visual system is anything but. They've got no fewer than 24 eyes of four different kinds. Now, researchers reporting online on April 28 in Current Biology, a Cell Press publication, have evidence revealing that four of those eyes always peer up out of the water, regardless of the way the rest of the animal is oriented. What's more, it appears that those eyes allow the jellies to navigate their way around the mangrove swamps in which they live. "It is a surprise that a jellyfish—an animal normally considered ...

For the first time, scientists have been able to paint a detailed chemical picture of how a particular strain of bacteria has evolved to become resistant to antibiotics. The research is a key step toward designing compounds to prevent infections by recently evolved, drug-resistant "superbugs" that often are found in hospitals, as well as in the general population. A paper describing the research, by a team led by Squire Booker, an associate professor in the department of chemistry and the department of biochemistry and molecular biology at Penn State University, will be ...

Several fish can be heard in... Click here for more information. Bruce Carlson stands next to a fish tank in his lab, holding a putty colored Radio Shack amplifier connected to two wires whose insulation has been stripped. At the bottom of the tank a nondescript little fish lurks in a sawed-off ...

The size and shape of the human cerebral cortex, an evolutionary marvel responsible for everything from Shakespeare's poetry to the atomic bomb, are largely influenced by mutations in a single gene, according to a team of researchers led by the Yale School of Medicine and three other universities. The findings, reported April 28 in the American Journal of Human Genetics, are based on a genetic analysis of in one Turkish family and two Pakistani families with offspring born with the most severe form of microcephaly. The children have brains just 10 percent of normal size. ...

(Millbrook, N.Y.) By closely monitoring environmental conditions at a remote Wisconsin lake, researchers have found that models used to assess catastrophic changes in economic and medical systems can also predict environmental collapse. Stock market crashes, epileptic seizures, and ecological breakdowns are all preceded by a measurable increase in variance—be it fluctuations in brain waves, the Dow Jones index, or, in the case of the Wisconsin lake, chlorophyll. In a paper published this week in the journal Science, a team of ecologists is the first to show that by paying ...

When the temperatures heat up dramatically, the air conditioner runs nonstop, putting a huge burden on the cooling system. It could help save money on energy costs and reduce your need for air conditioning repair in Los Angeles if you run your air conditioner efficiently. Precise Air Systems, Inc. provides helpful tips: - Set your thermostat at 78 degree Fahrenheit and leave it there. Moving the thermostat to a lower temperature setting won't get your home to 78 degree any faster. - Keep your blinds and curtains closed to keep the direct rays of the sun from entering ...

A large clinical trial comparing treatments for typhoid has recommended the use of gatifloxacin, a new generation and affordable antibiotic. The results of the trial in Kathmandu, Nepal, funded by the Wellcome Trust and the Li Ka Shing Foundation, are published today in the Lancet Infectious Diseases. Typhoid – also known as 'enteric fever' – is characterised by a high fever and diarrhoea. It is transmitted through the ingestion of food or drink contaminated by the faeces or urine of infected people. It causes an estimated 26 million infections each year and over 200,000 ...

Many older adults may be taking "excessive" doses of drugs for thyroid problems which can lead to an increased risk of fractures, finds a study published on bmj.com today. The study raises concern that treatment targets may need to be modified in the elderly and that regular dose monitoring remains essential even into older age. Levothyroxine is a synthetic form of thyroxine (thyroid hormone) and is widely used to treat an underactive thyroid gland (hypothyroidism). Most hypothyroid patients are diagnosed in early or middle adulthood but, as people age, their thyroxine ...

Biologists at UC San Diego have discovered that electrical oscillations in the brain, long thought to play a role in organizing cognitive functions such as memory, are critically important for the brain to store the information that allows us to navigate through our physical environment. The scientists report in the April 29 issue of the journal Science that neurons called "grid cells" that create maps of the external environment in one portion of our brain require precisely timed electrical oscillations in order to function properly from another part of the brain that ...

What Medicare would pay for and where a radiation oncologist practiced were two factors that strongly influenced the choice of intensity-modulated radiation therapy (IMRT) for treating breast cancer, according to an article published April 29 online in the Journal of the National Cancer Institute. The use of IMRT and the cost of radiation therapy increased sharply over the period of the study. IMRT is a radiation delivery technique that modulates the radiation beams to conform to the shape of the tumor or tumor bed in an attempt to maximize the dose of radiation to the ...

Researchers from Woods Hole Oceanographic Institution (WHOI) and their colleagues have discovered that massive, swirling ocean eddies—known to be up to 500 kilometers across at the surface—can reach all the way to the ocean bottom at mid-ocean ridges, some 2,500 meters deep, transporting tiny sea creatures, chemicals, and heat from hydrothermal vents over large distances. The previously unknown deep-sea phenomenon, reported in the April 28 issue of the journal Science, helps explain how some larvae travel huge distances from one vent area to another, said Diane K. Adams, ...

FINDINGS: Whitehead Institute scientists report that two proteins once thought to have only supporting roles, are the true "stars" of the kinetochore assembly process in human cells. RELEVANCE: The kinetochore is vital to proper DNA distribution during cell division. This finding suggests that scientists may be able to stimulate kinetochore assembly in a process that could lead to new genetic research tools, such as efficient creation of artificial human chromosomes. Widespread use of artificial human chromosomes has been thwarted by scientists' current inability to ...

Call it a mystery with a stubby tail: an odd-looking mouse discovered through a U.S. government breeding program in the 1940s that had a short, kinky tail and an extra set of ribs in its neck – and nobody knew why. A team of scientists led by researchers at the University of California, San Francisco has now spilled the genetic secrets of this mutant rodent. In doing so, they may have uncovered a new wrinkle in the genetic code – an entirely unrecognized way our bodies regulate how genes are expressed in different tissues throughout life. This discovery has broad implications ...

An international team of astronomers today revealed details of a "super-exotic" exoplanet that would make the planet Pandora in the movie Avatar pale in comparison. The planet, named 55 Cancri e, is 60 per cent larger in diameter than Earth but eight times as massive. Twice as dense as Earth – almost as dense as lead – it is the densest solid planet known, according to a team led by astronomers from the Massachusetts Institute of Technology (MIT), the University of British Columbia (UBC), the Harvard‑Smithsonian Center for Astrophysics and the University of California ...

One of the ocean currents which particularly interests oceanographers and climatologists is the Gulf Stream. This current, originating in the Gulf of Mexico, transports enormous amounts of warm tropical waters to the North Atlantic and is the cause of Europe's habitable climate. Climate predictions point to the fact that this will change in the future and affect especially the climate in countries of the Mediterranean region, with more dry spells. As global warming progresses, the North Atlantic will receive more precipitation and a greater amount of water from the melting ...

Fish and marine species are among the most threatened wildlife on earth, due partly to over exploitation by fishing fleets. Yet there are differences in assessing trends in worldwide fishing stocks which, researchers writing in Conservation Biology argue, stem from inappropriate use of time trends in catches. "Estimates of fishery status based on catches suggest that around 30% of fisheries are collapsed and 70% are overexploited or collapsed," said lead author Dr Trevor Branch from the University of Washington in Seattle. "Our assessment shows that the data are seriously ...

People with rare diseases have the same right to high-quality health care in line with current medical knowledge as other patients do. However, relevant and reliable clinical studies on rare diseases are often lacking. Among other things, this makes the development of corresponding guidelines more difficult, but precisely such guidelines could help improve treatment quality. The German Federal Ministry of Health therefore commissioned the Institute for Quality and Efficiency in Health Care (IQWiG) to answer the following question: What methodological approaches are used ...
