Cell shocked

Researchers at USC's Viterbi School have developed a new electric pulse technology called electroperturbation, which exposes cells to brief and intense electric pulses that can trigger cell death. The technique has advantages over conventional treatments, being non-invasive and able to deliver treatment remotely.

AGU journal highlights - 10 March 2004

Researchers developed a method to estimate background levels of heavy metals in soil, allowing for the estimation of manmade contamination worldwide. A new analysis of satellite data provided detailed information on tropical Atlantic surface current variability, which can be used to infer global ocean patterns. Additionally, a simple m...

Stress hormones and heart failure

Researchers have found that urocortin II administered intravenously significantly enhances heart muscle cell contractions in mice with congestive heart failure. The hormone targets the CRF2 receptor, leading to improved cardiovascular function and a potential new treatment for heart disease.

Crucial brain development gene identified

Researchers have identified a critical gene called Lgl1, which plays a vital role in shaping cell behavior during embryonic brain development. The study found that mice lacking this gene exhibit dramatic abnormalities and resemble human patients with medulloblastoma, a type of brain tumor.

Study on sub-millimeter telescope on Chile mountain

Cornell University and Caltech researchers will develop the world's most sensitive sub-millimeter telescope in the Atacama Desert, capable of probing star formation during galaxy formation. The telescope's high sensitivity will enable studies of large-scale universe structure and hidden planets in circumstellar disks.

Researchers identify clues about marijuana effects

A study published in the Journal of Pharmacology and Experimental Therapeutics reveals how cannabinoids produce hypothermia, a decrease in body temperature. The research suggests that nitric oxide plays a role in regulating cannabinoid-induced hypothermia.
