Infection detectives use disease 'fingerprints' to track common infections in children

...tting, such as an emergency room. "When a child comes in with a fever to the ER, we want to see if we can predict who just has a virus and can go home, and who has to be admitted and put into the intensive care unit and treated with antibiotics. That’s our goal," said Dr. Ramilo. "This is just the first...

New biofuels process promises to meet all US transportation needs

...ly, the hydrogen in liquid fuels made from biomass comes from the plant matter itself. But it typically takes more than 10 times the solar energy to grow crops than it does to produce the equivalent quantity of hydrogen possessing the same energy content by using the solar-power electrolysis method, he sai...

Gene that makes people 'early to bed and early to rise' demystified

...ork. But this paper shows that is not the case. It comes back instead to the transcription level as the most important step." FASPS is a relatively rare, inherited condition in which people are "morning larks," with early morning awakening and early sleep times. People with the condition generally show c...

Bats prey on nocturnally migrating songbirds

...y passerines. Actually, the newly uncovered danger comes from the deep black sky, in the form of a 45 cm wing-spanned aerial-hawking mammal, equipped with sharp canines and an efficient radar system which remains probably largely inaudible to songbirds. In 2001, Carlos Ibáñez and his colleagues at the ...

Genes may determine success of hip replacement surgery

...escribes a condition in which the artificial joint comes loose and the surrounding bone begins to dissolve. The other 71 patients had deep-seated infection, which occurs when the body is unable to control infection caused by bacteria colonising the artificial implants. DNA samples were taken from all pa...

Lost dogs found more often than lost cats, study suggests

... own. "Many people think that a missing cat just comes home on its own," Lord said. "Most of the lost cats that were recovered in our study did return home on their own, but nearly half of the cats reported missing were never found." More than one out of three owners (35 percent) found their lost dogs ...

UF scientists discover new genus of frogmouth bird in Solomon Islands

..."They’ve barely been studied, much of what we know comes from antiquated or casual observations," Remsen said. "The biology of birds in these regions is, to a great extent, obscured by stale, hand-me-down classifications from an earlier era. A combination of detailed morphological and genetic analyses reve...

Stopping plants from getting sick

...gi, a group of pathogens with an unusual name that comes from the sooty black masses of spores that they form on infected plants. The smut fungi represent particularly useful models to study how pathogens infect crop plants. These fungi depend on the infection of a plant to complete part of their life cycl...

Antibody signal may redirect inflammation to fuel cancer

...a more threatening stage. The new UCSF finding comes from studies with mice genetically engineered to carry some of the genes of the human papilloma virus (HPV), a pathogen that is known to cause human cervical cancer. By comparing cancer progression in these mice compared with gene "knock-out mice" th...

Bird sex is something else

...out the birds and the bees. But apparently when it comes to birds, they have an unusual take on his and hers ?and the difference is genetic. Species with differentiated sex chromosomes (X and Y in humans, for example) get around the fact that males and females get different-sized portions of sex chromosome...

Living with water scarcity -- world must act now

... calorie. A main driver of water use and scarcity comes from us ?and what we eat. As a rule of thumb, about one litre of liquid water gets converted to water vapor to produce one calorie of food. "Each of us is responsible for consuming between 2,000 and 5,000 liters of water every day, depending on our...

Neural bottleneck found that thwarts multi-tasking

...aul E. Dux and René Marois have found that when it comes to handling two things at once, your brain, while fast, isn't that fast. "Why is it that with our incredibly complex and sophisticated brain, with 100 billion neurons processing information at rates of up to a thousand times a second, we still hav...

Scientists re-grow dental enamel from cultured cells

...problems remain to be solved before the technology comes close to being tested in humans. One of the issues has been how to produce, in culture, sufficient numbers of enamel-forming cells. Today, during the 85thth General Session of the International Association for Dental Research, a team of researchers ...

Scripps Research study reveals new activation mechanism for pain sensing channel

...nel activation." But this activation mechanism comes with an interesting property. "Generally, compounds that activate ion channels bind in a lock-and-key mechanism that is readily reversible," said Lindsey Macpherson, another author of the study and a Ph.D. candidate in the Scripps Research Kellog...

100 percent juices found as beneficial to health as fruits and vegetables

When it comes to some of today’s health issues, 100 percent fruit and vegetable juices do help reduce risk factors related to certain diseases. This conclusion is the result of a European study designed to question traditional thinking that 100 percent juices p...

Brain works more chaotically than previously thought

...Nobody knew until now where the glutamate actually comes from," says Dr. Dietrich. "Our results might open the door to totally new therapeutic options." After all, drugs have already been developed that prevent glutamate bubbles from discharging their load into the brain. Indeed, Bonn's neuroscientists now...

Breathing easy: When it comes to oxygen, a bug's life is full of it

...n of live bugs. This advance in technology also comes at a time when physiologists are learning more about the genes that control breathing. When physiologists gather at the symposium, they will assess these new developments and consider a roadmap for future research, said Kirkton. The symposium, whi...

Protein averts cell suicide but might contribute to cancer

...sn't known. The Dpo4 protein used in this research comes from a microorganism. It is relatively easy to produce in large quantities and to study, and it is similar to one of the four such enzymes found in humans. For this research, Fiala developed a new way to sequence very short lengths of DNA. "This ...

Stem cells engage in dialogue with the cells that regulate their futures

...y well be that the power of cancer cells to spread comes from this natural ability of stem cells to make a home when in a hospitable environment. We all need a home, and stem cells with their strong survival instinct are active homebuilders." ...
