Progress toward an antitumor vaccine

...ns of a spacer,” explains Kunz. This would be very easy to accomplish with polysaccharides, but turns out to be very complicated with glycoproteins, because the protein portion of the molecule has many reactive groups that are attacked in the coupling reaction. “In addition,” says Kunz, “many of the struc...

Penn researchers link cell's protein recycling systems

...tissue, as a surrogate for the brain because it is easy to visualize. They discovered that making the lysosomal system more or less active dramatically influenced the severity of neurodegeneration. “We found that whenever we knocked the lysosome system down, neurodegeneration always got worse,” says T...

Exploring the dark matter of the genome

...aches to finding genes, Smith says, are relatively easy to perform in euchromatin but harder in heterochromatin, "because it is so rich in repeats." Smith and his colleagues found evidence for 230 to 254 protein-coding genes in the heterochromatin, previously thought to contain a mere 30 to 40 (the fl...

Male circumcision overstated as prevention tool against AIDS

These men then act as a conduit to bring the virus home to their villages, their other casual sex partners and to their wives. The study has important pol...

Healthy coral reefs hit hard by warmer temperatures

The research is innovative due to a multidisciplinary approach, in which methods from various disciplines such as ecology, toxicology, molecular biology and evolutionary biology provide insights into the effect of soil pollution...

No magic tomato? Study breaks link between lycopene and prostate cancer prevention

...inson Cancer Research Center. "Unfortunately, this easy answer just does not work." Previous studies suggested that a diet rich in lycopene protected against prostate cancer, spurring commercial and public interest in the antioxidant. Antioxidants protect against free radicals, highly reactive atoms a...

Hives ferment a yeasty brew, attract beetle pest

...ves. European honeybees were bred to be docile and easy to work with, while African honeybees are noted for aggression and a propensity to sting. The beetles were first seen infesting U.S. beehives in Florida in the late 1990s. The researchers tested the response of both the small hive beetles and hone...

Researchers wake up viruses inside tumors to image and then destroy cancers

...ut TK," Pomper says. "An injection of FIAU made it easy to image the tumors with virus in them." The method is highly sensitive, he says: as few as five percent of the cells within the tumor mass needed to be induced into the lytic cycle in order to be detected. Not only can FIAU light up the tumors...

Such monitoring has become vital since saiga have seen a dramatic decline in numbers of over 95% in recent years, making them one of the most critically endangered species on earth. Future rese...

Imaging pinpoints brain regions that 'see the future'

...inton was chosen because pre-testing showed he was easy for participants to visualize in a variety of situations. Comparing images of brain activity in response to the "self-remember" and "self-future" event cues, researchers found a surprisingly complete overlap among regions of the brain used for rem...

Metacognition: Faced with a test, rats can check their knowledge first

But prior to the time-discrimination test, rats were given a choic...

"We propose that jumbo squid are more susceptible to predation while they are recovering at depth immediately after a deep nighttime dive," he explained. In previous studies, Gilly ...

Bypassing eggs, flu vaccine grown in insect cells shows promise

...ruses can be temperamental, and it’s not always an easy matter to get the virus to grow as you want in eggs.? The use of cell culture systems to grow vaccines ?using viruses as tiny factories to churn out mass amounts of vaccines ?is a growing business. A similar technology using human cell lines is use...
