Chemists create 'Superbowl' molecule; May lead to better health

...a hydrogen molecule, a superbowl molecule can hold large molecules of up to a hundred atoms, particularly those of medicinal value, Sherburn says. "I'm sure that we will be able to encapsulate compounds such as [the anticancer drug] taxol in the near future," he says, but cautions that the superbowl molec...

Molecular biology fills gaps in knowledge of bat evolution

...r results support the hypothesis that the group of large fruit-eating bats from the tropics, that fly mostly during the day - known to biologists as megabats - emerged from four major lineages of smaller and more widely dispersed, mostly insect-eating, night-flying bats, known as microbats. These microbats...

UCSB scientists probe sea floor venting to gain understanding of early life on Earth

Source of molecular triggers in cutaneous T cell lymphoma identified

...Cell Lymphoma (CTCL) cells to clonally expand into large populations of malignant lymphocytes. CTCL is the most common adult malignancy of T lymphocytes, the white blood cells of the immune system. Finding CTCL triggering factors has been a major goal of Richard L.

New binding target for oncogenic viral protein

...lishes this task by producing the highly oncogenic large T antigen. This protein corrupts the cellular checkpoint mechanisms that guard cell division and the transcription, replication and repair of DNA. T antigen also inactivates some of the most important proteins that protect cells against malignant tra...

Neuronal 'traffic jam' marks early Alzheimer's disease

...e obvious axonal defects," said Goldstein. "We saw large swellings in their axons. And when we looked at those swellings using electron microscopy and biochemical markers, they looked just like the axonal transport blockages we saw in fruit flies." Detailed studies of the neurons revealed what Goldstein te...

Termites feed through good vibrations

Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

...s drug targets." The project also identified some large families of surface proteins that may help mediate the amoeba's ability to evade the human immune system. This could explain why the parasite can stay hidden in the body for years at a time. Such information may help researchers find better means to ...
