Living with water scarcity -- world must act now

...s 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 diet and how the food is produced ?far more than the 2 to 5 litres we drink every d...

Statin plus cancer drug deliver combo punch to brain cancer cells

...ater insights into its blockage of hedgehog, which gets its name from spiky hairs that develop on fruit flies lacking the signal. "We already knew from earlier research that hedgehog controls brain cell survival and growth, and that blocking signals in this pathway may stop uncontrolled growth of cancer...

The origin of the brain lies in a worm

...ated how the developing CNS in Platynereis embryos gets subdivided into the regions that later on give rise to the different CNS structures. The regions are defined by the unique combination of regulatory genes expressed, which endow every type of neuron with a specific molecular fingerprint. Comparing th...

Researchers hot on the trail of brain cell degeneration

... and globally. Cooperation between biocentres gets research going The teams' study is a perfect example of the cooperation between biocentres in Finland (Biocenter Finland) and international networking. The research was funded mainly by the Academy of Finland and the European Union. The two resea...

Chemical switch triggers critical cell activities

...ated form of E2 that binds to the docking site and gets near NEDD8, but cannot form a thioester bond with it. The team reasoned that if E2 could not bind to NEDD8, it would be stuck on the docking site with nothing to do and nowhere to go. An X-ray crystallography image could then capture that moment. ...

New molecular pathway could reveal how cells stick together

...entified a specific protein, called ninjurin, that gets cut by MMP. Now she is working out the interplay between MMPs and ninjurin, with the goal of characterizing this previously unknown pathway by which cells signal to each other. Ninjurin is anchored to the surface of cells, but after being cut by M...

Cartilage discovery offers arthritis hope

...joint. Scientists have long known that cartilage gets its strength from interlocking millimetre-long collagen fibres that work in a similar way to the load-bearing steel rods in reinforced concrete. But the precise structure of these fibres or 'fibrils' has remained a mystery for more than 40 years, s...

'Night owls' report more insomnia-related symptoms

...ptoms of insomnia. The amount of sleep a person gets affects his or her physical health, emotional well-being, mental abilities, productivity and performance. Recent studies associate lack of sleep with serious health problems such as an increased risk of depression, obesity, cardiovascular disease an...

...ination and, second, ensure that whatever is there gets well preserved because it can be interrogated." The scraps of dinosaur protein were wrested from a fossil femur discovered by John Horner, of the Museum of the Rockies, and colleagues in 2003 in Hell Creek Formation, a barren fossil-rich stretch o...

Renegade RNA -- Clues to cancer and normal growth

...ly goes where no bit of it has gone before, and it gets there under its own internal code. A report on the renegade ribonucleic acid, and the code that directs its movement, will be published Jan. 5 in Science. MicroRNAs, already implicated in cancer and normal development, latch on to and gum up larg...

Robotic exoskeleton replaces muscle work

...tificial) muscles are pneumatic. When the computer gets the electrical signal from the (wearer's) muscle, it increases the air pressure into the artificial muscle on the brace," Ferris said. "Essentially the artificial muscle contracts with the person's muscle." Initially the wearer's gait was disrupt...

Selectivity is ultimate aphrodisiac

...ocated. (Think hallelujah, finally, someone really gets me.) In the past, social psychologists have had a difficult time observing initial romantic attraction in action, but the speed-dating methodology used in this study allowed the investigators to take a serious look at the chemistry that has been ...

In young mice, gregariousness seems to reside in the genes

...hvis explains. "The initial genetic predisposition gets masked by reproductive maturity." This result is crucial, argue Lahvis and Panksepp, because it suggests that the genetic influences on juvenile social behavior may be quite distinct from genetic factors that affect adult social behavior, a findin...

Sleep quantity affects morning testosterone levels in older men

...erences in the amount of sleep a healthy older man gets can affect his level of testosterone in the morning, according to a study published in the April 1st issue of the journal SLEEP. The study, conducted by Plamen Penev, MD, PhD, of the University of Chicago, focused on 12 healthy men between the ages ...

Hives ferment a yeasty brew, attract beetle pest

...produced. "We are not really sure how the yeast gets into the colony," says Tumlinson. "Perhaps one beetle finds and carries the yeast in and it reproduces, or, because the yeast grows on pollen in nature, perhaps bees bring it into the hive." This combination of domestic honeybees, small hive beet...

Iowa State scientists demonstrate first use of nanotechnology to enter plant cells

Study shows continued success for new HPV vaccine against virus responsible for cervical cancer

...es and we were 98 percent effective. Everyone who gets cancer goes through a pre-cancerous stage," says Ault. "There are about 50 to 60 million pap smears performed each year in the US, and about seven percent are abnormal. We spend about 3 billion dollars each year to find and treat these pre-cancerou...

Genetic roots of bipolar disorder revealed by first genome-wide study of illness

...riations in them influence whether or not a person gets a specific disease. In this study, researchers compared variations found in the scans of 413 adults who had bipolar disorder with variations found in the scans of 563 healthy adults. By pooling the genetic material of the adults with bipolar dis...
