Journal Club: Low-calorie diets might improve effectiveness of cancer treatments

The old saying goes, “feed a cold, starve a fever”—now scientists might add, “starve a tumor.” In mice, a low-protein, low-calorie diet sensitizes breast cancer and melanoma cells to attack by the immune system, while prodding the immune system itself … Continue reading

Journal Club: New ability to measure the recoil from single photons could help address fundamental physics mysteries

Scientists have for the first time directly measured the recoil that single photons exert on levitating nanoparticles in a vacuum. The work that could help lead to more sensitive measurements of ultra-weak forces, according to research detailed online June 13 … Continue reading

Journal Club: Mosquito saliva inflames immune system to spread viruses, suggesting possible interventions

The quick, piercing bite of a mosquito leaves behind a tiny amount of saliva under the skin of its prey. This saliva has been shown to have potent effects, such as numbing the pain of the bite and preventing blood … Continue reading

Journal Club: Even infants intuitively infer how others minimize costs and maximize rewards

A growing body of research suggests that people have a commonsense psychology — an intuitive way to infer what others want and might decide — that is already sophisticated from infancy. Now researchers have proposed a model for this commonsense … Continue reading

Journal Club: “Zombie” HIV RNA could cause ongoing damage

Streaming through the blood of people with HIV are cells carrying mutant, incomplete viral genomes—viral DNA sets that researchers have long deemed duds, irrelevant to disease. But a study in PNAS this week refocuses attention on these defective viral tagalongs. … Continue reading

Journal Club: Ancient fish moving to land used their tails as crutches

The evolution from fish living in water to vertebrates living on land was one of the most pivotal moments in the history of the animal kingdom. Now scientists using robot fish suggest that these ancient pioneers may have used their … Continue reading

Journal Club: Microvesicles facilitate crucial signals in developing embryos

Early in mammal development, tiny vesicles provide key communication between the cells that will become the fetus and those destined to form the placenta, researchers have found. The message the microvesicles are imparting: It’s time to implant into the wall … Continue reading

Journal Club: 3-D Microtumor Model Offers New Insights into Tumor Progression

Most cancer-related deaths are caused by metastasis, as cancers spreads to sites throughout the body. Breast cancer metastasis is strongly associated with tumor size, and scientists want to better understand how these factors are linked. Now researchers have developed a … Continue reading

Journal Club: Peering beneath Jupiter’s uppermost clouds

Astronomers have trained telescopes on Jupiter since Galileo, but much about what lies under the giant world’s uppermost clouds was a mystery. Now the most detailed radio map yet of Jupiter’s atmosphere reveals it is dynamically active beneath these clouds, … Continue reading
