Hybrid molecule causes cancer cells to self-destruct

...dical engineering who supervised the project. "Our insight was to select the sugar partner to serve not just as a passive carrier but as additional ammunition in the fight against cancer." The researchers focused on a sugar called N-acetyl-D-mannosamine, or ManNAc, for short. The team created a hybrid mol...

Wired for sound: How the brain senses visual illusions

...s in the brain. Their findings, which provide new insight into neural mechanisms by which visual perception can be altered by concurrent auditory events, will be published online in the April 12 edition of the Journal of Neuroscience. When subjects were shown a single flash of light interposed between two...

Researchers discover gene crucial for nerve cell insulation

In histological and physicochemical examinations in collaboration with HASYLAB, the synchrotron laboratories based in Hamburg, German...

Scripps research study reveals structural dynamics of single prion molecules

...es, consisting of multiple protein molecules. This insight may be important to finding potential new therapeutic targets for disease-causing amyloids." To define the dynamic structural details of individual prions, Deniz and his colleagues employed several novel technologies including single-molecule fluo...

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

...eristic shifted sleep pattern. Eventually, such insight into the factors influencing people's so-called circadian, or daily, rhythm might lead to therapies that could adjust the body's clock in those suffering from conditions including jet lag or shift work sleep disorder, according to the researchers. ...

Paleontologists discover new mammal from Mesozoic Era

...s mammaliaforms. "This new fossil offers a rare insight in the evolutionary origin of the mammalian ear structure," said Zhe-Xi Luo, a paleontologist at the Carnegie Museum of Natural History (CMNH) in Pittsburgh, Pa. "Evolution of the ear is important for understanding the origins of key mammalian adapta...

RNA enzyme structure offers a glimpse into the origins of life

...d to make new RNA molecules. Their results provide insight into what may have been the first self-replicating molecule to arise billions of years ago on the evolutionary path toward the emergence of life. In all forms of life known today, the synthesis of DNA and RNA molecules is carried out by enzymes made...

Out of Africa -- Bacteria, as well

...s of the world. This has also given scientists new insight into the paths taken by man as he journeyed across the Earth (Nature online, February 7, 2007). More than half of all human beings are infected with Helicobacter pylori, a bacterium that can cause stomach ulcers. Like humans, the bacteria are als...

Study uncovers a lethal secret of 1918 influenza virus

...h. The finding is important because it provides insight into how the virus that swept the world in the closing days of World War I was so efficiently deadly, claiming many of its victims people in the prime of life. The work suggests that it may be possible in future outbreaks of highly pathogenic flu to ...

Studies yield insight into the numerical brain

...rs. The researchers also said their findings offer insight into the mystery of how the brain learns to associate abstract symbols precisely with quantities. Both studies reveal in unprecedented detail how structures in the parietal cortex--the region of higher cognitive processing just above the forehead--a...
