Cannabinoid receptor necessary, but can’t be overloaded, mouse model shows

Marijuana use may increase the risk of ectopic (tubal) pregnancies, researchers at Vanderbilt University Medical Center reported this week. The researchers studied CB1, a “cannabinoid” receptor that binds the main active chemical for marijuana, delta-9-tetrahydrocannabinol (THC).

In pregnant mice that lacked the gene for the receptor, or in which the receptor was blocked, the embryo failed to go

Mesothelioma is an aggressive cancer of the chest cavity that kills about 2000 people a year in the United States. Seventy to eighty percent of patients with this rare cancer have had exposure to asbestos. It has also been proposed that simian virus 40 (SV40), a contaminant in some polio vaccines administered in the 1950’s and 1960’s, might be a cause. However, studies reporting the detection of SV40 DNA in human tumors (including mesotheliomas, and also some lymphomas, brain cancers, an

While researchers in Alaska this summer used high-tech submersibles and huge ships to plumb the deep-ocean depths in search of new species, a team of scuba diving scientists working from an Alaska fishing boat has discovered an entirely new marine habitat just a stone’s throw from shore.

The discovery in June of a single bed of rhodoliths, colorful marine algae that resemble coral, was made near Knight Island in Prince William Sound by scientists at the University of Alaska Fai

The issue (31 august) of the US scientific journal Proceedings of the National Academy of Sciences (PNAS), one of the most prestigious in the world, carries an article on important aspects related to a molecule (ADPglucose) which is required for plants to produce starch.

In order to assess the importance of this research of the Public University of Navarre, two fundamental factors have to be taken into account: one is the annual production of starch derived from the main vegetables a

A new study being carried out at the University of Leicester traces the erosion of the traditional concept of Maasai manhood and the emergence of new role for Maasais- reliving their warrior dreams in paid employment, business or trading in livestock.

The romantic notion of the ‘noble savage’ Maasai warrior, replete with traditional ponytails and weapons- a key image for tourism in Kenya – masks a crisis of cultures that has blighted this once proud tribal race, according to a study

When earthquakes strike, people often get trapped in buildings. Search and rescue teams can pinpoint some victims using sniffer dogs and sensors. But a new European system that takes pictures during or after a building collapse promises to save many more lives.

The ‘low-cost catastrophic event capturing system’ is the fruit of the IST Loccatec project. It comprises capturing devices (small, autonomous infrared cameras) and a portable central unit for the rescue teams. The cameras – p
