Researchers uncover how cancer cells override environmental cues to consume energy

Using human lung cancer cells, UT Southwestern researchers have uncovered how cells in general modulate their energy consumption based on their surroundings and, furthermore, how cancer cells override those cues to maximize energy use.

Clemson researchers discover protein function in parasites which afflict millions with diseases

In the quest to develop more effective treatments for parasitic diseases like African sleeping sickness, Chagas disease and Leishmaniasis, scientists look for weaknesses in the organisms' molecular machinery. These weaknesses can then be targeted with drug therapies designed to kill the parasites.

Researchers develop new probe to detect common target of anti-inflammatory drugs

The Chan group at the Beckman Institute for Advanced Science and Technology has recently developed a probe named CoxFluor, which is able to distinguish between Cyclooxygenase-2, an enzyme that plays a major role in driving the progression of cancer, and Cyclooxygenase-1, which is expressed in all cells.

Technique used to study human epidemiology reveals coral disease risk factors

In a study published in Scientific Reports, a team of international researchers led by University of Hawaii at Mānoa postdoctoral fellow Jamie Caldwell used a statistical technique typically employed in human epidemiology to determine the ecological risk factors affecting the prevalence of two coral diseases--growth anomalies, abnormalities like coral tumors, and white syndromes, infectious diseases similar to flesh-eating bacteria.

Using 'mini-brains' to detect harmful neurodevelopmental effects of antidepressant

Researchers at Johns Hopkins Bloomberg School of Public Health have demonstrated the use of stem-cell-derived "mini-brains" to detect harmful side effects of a common drug on the developing brain.

Active droplets for precise dosing of medication

Using a mixture of oil droplets and hydrogel, medical active agents can be not only precisely dosed, but also continuously administered over periods of up to several days. The active agents inside the droplets are released at a constant rate, decreasing the risk of over- or underdosage.

Study shows what drives an ordered row of alternating peptides

A team of researchers has verified that it is possible to engineer two-layered nanofibers consisting of an ordered row of alternating peptides, and has also determined what makes these peptides automatically assemble into this pattern.

Oxidative stress induces sleep in fruit flies, research shows

Sleep-deprived fruit flies helped reveal what induces sleep. University of Oxford researchers Anissa Kempf, Gero Miesenböck, and colleagues reveal that fruit fly sleep is driven by oxidative stress, the imbalance of free radicals and antioxidants in the body. Kempf

Novel formulation allows use of toxin from rattlesnake venom to control neuropathic pain

Crotoxin, extracted from the venom of the South American rattlesnake Crotalus durissus terrificus, has been studied for almost a century for its analgesic, anti-inflammatory and antitumor activities and as an even more powerful muscle paralyzer than botulinum toxin.

Research reveals new pathogenic mechanism for influenza NS1 protein

Influenza is a deadly virus, with about 290,000 to 650,000 deaths worldwide each year. When pandemics hit, the toll can soar: The Spanish flu of 1918 caused 40 million to 50 million deaths, the Asian flu of 1957 caused 2 million deaths, and the Hong Kong flu of 1968 caused 1 million deaths.
