Journal Club: Cooler temperatures might make some mosquitoes better dengue spreaders

Migrating mosquitoes that carry diseases from the tropics to cooler climes might be better at spreading disease in their new, cooler home, according to a recent study in the Proceedings of the Royal Society B. Researchers from Yale University in … Continue reading

Journal Club: Antarctic cyanobacteria show no changes due to warming—yet

Captain Robert Scott’s Antarctic Discovery expedition took place over 100 years ago—and yet its participants recently racked up another contribution to science. Thanks to the samples of bacterial mats they collected from polar ponds—samples that were pressed, dried, and stored … Continue reading

Journal Club: Geometry of Greenland’s glaciers helps predict future ice melt

The changing climate is just one factor contributing to the melting and thinning of the slow-moving rivers of ice that terminate in spots such as Greenland’s fjords. Each glacier’s geometry—including its thickness and how steeply it flows—also makes a difference. … Continue reading

Journal Club: Layer-cake chemistry offers up a cheap way to perform chemical tests

Sana Jahanshahi-Anbuhi started her study with a trip to the supermarket to buy Listerine breath strips, the sort that melt on your tongue in seconds. But the chemical engineering postdoc at McMaster University in Hamilton, Canada wasn’t worried about bad … Continue reading

Journal Club: How much you think you understand depends on what you believe others understand

Knowing that experts understand something is enough to make lay persons think they, too, have better grasped a concept, according to a September 26 paper in the journal Psychological Science. Cognitive scientist Steven Sloman, of Brown University in Providence, Rhode … Continue reading

Journal Club: Childhood adversities correlated with shortened telomeres, poorer health later in life

Stressful experiences during youth seem to leave a mark on a person’s genome decades later, in the form of withered chromosomal caps. As reported in PNAS, childhood stress correlates with increased odds to have shortened telomeres, the chromosome tips that … Continue reading

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: “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: 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: Mutations in non-coding gene signal risk of celiac disease

Researchers struggling to find genes linked to celiac disease may have been looking in the wrong place. Recent findings have uncovered a gene that appears to amplify risk for the common autoimmune disorder by spelling out not a protein, but … Continue reading
