Study in Science holds promise for a new approach to drug therapy

...or allows parts of itself, the G protein, to break away on the inside of the cell, kicking off a series of reactions there. Once free, a G protein itself breaks up into an alpha subunit and a tightly paired gamma-beta subunit. G proteins subunits, in effect, pass on the biological message inside the cel...

Expedition discovers marine treasures

...shermen of Saba in their small boats, forcing them away from traditional fishing grounds and causing the loss of fish pots that become so-called ''ghost traps" that harm fish stocks. Leroy Peterson, a Saba fisherman, called the expedition crucial for protecting Saba Bank's unique marine life. "Some of t...

New cellular flaw found in some virulent breast cancers

...are going to see in the next five years a movement away from treating all tumors with the same drugs, and instead match specific drugs to tumors based on their molecular characteristics," said Sicinski, who is also an associate professor of pathology at Harvard Medical School. Cyclin D1 is one of a famil...

Researchers develop portable 'vein finder' for faster, more accurate injections

...od flow to distinguish arteries (which carry blood away from the heart) from veins (which carry blood to the heart). Once the device detects a vein, an alarm is triggered, and medics insert the needle. The vein finder has proved highly effective in initial tests on phantom tissue, a model that simulates...

New University of Toronto research a 'pore' excuse for engineering

...e into a nanostructure. The scientists then washed away the surfactant to leave a nanoporous material. When they examined the thin film that remained, they discovered that it made an excellent insulator that could be used to separate tiny wires inside microelectronics. "It demonstrates how creative chemi...

Flesh-eating bacteria escape body's safety net

...ssolved the DNA nets and allowed bacteria to float away from the neutrophils. "The experiments explain how this DNA-degrading enzyme contributes to the severe infections produced by certain strains of Strep bacteria, while simultaneously confirming just how important neutrophil DNA nets are to our normal...

Horseshoe crab decline threatens shorebird species

...atory and eating behaviors, scientists from as far away as Australia frequently travel to the Delaware Bay to study this rare species. "Biologists with the Delaware and New Jersey divisions of fish and wildlife have been very helpful during this project, and they welcome researchers from all over the wo...

2005 was the warmest year in a century

...ave warmed. Because these areas are remote and far away from major cities, it is clear to climatologists that the warming is not due to the influence of pollution from urban areas. ...

Pair of studies offer new clues to combat antibiotic resistance

...ams caution that these new approaches may be years away from human testing and clinical use. Even if effective, bacteria can eventually develop ways to circumvent even the best laid approaches, underscoring the need for a better understanding of resistance machinery and the availability of new antibiotics...

Hot-spring bacteria flip a metabolic switch

...c N2-fixing bacteria that live in their roots, far away from the photosynthetic leaves. A different type of cyanobacteria grows in multicellular strands and makes specialized N2-fixing cells called heterocysts that are walled off from the photosynthetic cells. Many researchers believed these filamentous ...

Antibacterial coatings cut infection rates

...he surface, making it impossible for them to break away and travel into remote organs such as the brain or liver," Professor Griesser said. UniSA PhD student in applied science (minerals and materials), Sameer Al-Bataineh, has developed a fundamental understanding of the antibacterial coatings and how to...

Picking particles faster than one at a time

...d brightness are retained; all the rest are thrown away in a step called binarization, or thresholding. "You need not know how the particle looks before you set out to pick good images of it, only how big it is," says Adiga. The thresholding procedure is iterative, but eventually the processed high-cont...

Study finds that nutritionally enhanced rice reduces iron deficiency

...genda, and the rice research agenda in particular, away from quantity and toward better-quality food. This may be the start of a nutritional revolution--a very appropriate follow-on from the Green Revolution and one that is desperately needed by millions of the world's poor and undernourished." ...

ASU researchers 'wire' DNA to identify mutations

...he electrodes spontaneously. As the tip is pulled away and the two electrodes teased apart, the molecules of DNA are eventually dispersed to the point of measuring the current of a single DNA molecule. For a proof of concept of the potential for measuring SNPs, the group used DNA of 11 or 12 bases in l...

Wild Gorillas Handy with a Stick

... including moss as sponges and leafy twigs to swat away bees.) That no one has ever observed wild gorillas using tools—despite decades of intensive study—prompted scientists to speculate that gorillas lost the skill because they didn't need it. The largest of the great apes, gorillas can gnash nuts betwee...
