Journal Club: Tracking memories in fruit fly brains

Memories help animals make predictions. A honeybee may remember that the smell of orange blossoms means nectar is nearby. But sometimes memories require updating. “If you know that your fridge is a good source of food, and you go to … Continue reading

Journal Club: Super-sensitive new microscope uses ultracold atoms to image magnetic fields at high precision

In recent years, physicists have developed an arsenal of sensitive, high-resolution tools to probe the smallest magnetic fields, revealing nanoscale subtleties lost in larger-scale measurements. An understanding of these structures can offer insights into exotic quantum materials. A new microscope … Continue reading

Journal Club: In some cases, water management practices exacerbated California drought, according to model

Many of California’s reservoirs are now fuller than they’ve been in years thanks to an extraordinarily wet winter. Yet drought conditions are likely to return based on historical cycles, even without accounting for climate change. And California’s depleted groundwater is … Continue reading

Journal Club: Antibiotics alter the honeybee microbiome and increase bee death

Antibiotics could potentially disrupt the health-promoting microbes that make up the microbiomes in humans and other animals. But pinning down exactly how microbiomes and antibiotics affect human health is complicated by the sheer number of microbes involved. Evolutionary biologist Nancy … Continue reading

Journal Club: Potential life could have spread with relative ease amongst newly-discovered group of seven exoplanets

The odds of life spreading between the worlds of the newly-discovered seven-planet TRAPPIST-1 system are up to 1,000 times greater than in our own solar system. That’s the conclusion of a new analysis posted March 2 to the arXiv, an … Continue reading

Journal Club: Shark blood compound offers up novel mechanism for stabilizing folded proteins

Sharks and other sea life often maintain high levels of trimethylamine N-oxide (TMAO) in their blood, a compound vital to their surviving in the saline environment. TMAO helps maintain an osmotic balance between body tissues and sea water to prevent … Continue reading

Journal Club: Newfound avenue for disrupting peroxisome organelles could have big implications in the cell

Peroxisomes are packages of enzymes that help destroy toxins and digest fuels for cells. Disrupt the assembly of these organelles, and the results could be fatal for humans. Previously, all mutant proteins linked to such disorders were thought to be … Continue reading
