We summarize the week's scientific breakthroughs every Thursday.
- Neuroscience
How a fat hormone might make us born to run
Many runners finish long races in a euphoric mood. The underpinnings of this runner’s high may involve many chemicals, including the fat hormone leptin.
- Animals
Alpine bee tongues shorten as climate warms
Pollinators’ match with certain alpine flowers erodes as climate change pushes fast evolution.
- Health & Medicine
What makes cells stop dividing and growing
Scientists have found that the protein GATA4 helps control cellular senescence, and may be a target for treating aging-related diseases.
- Paleontology
New dinosaur identified in Alaska
New species of duck-billed dinosaur discovered in the Alaskan permafrost.
- Life
For people, mealtime is all the time
People eat for most of their waking hours, which may affect sleep and weight.
- Neuroscience
Separate cell types encode memory’s time, place
Cells called ocean cells help store a memory’s “where,” while other cells called island cells help store a memory’s “when.”
- Animals
How to see sea turtles — without bothering them
Sea turtles come out of the water to lay eggs on beaches. It’s a great time to see the reptiles — if you know what you are doing.
- Animals
These fish would rather walk
Slowpokes of the sea, frogfish and handfish creep along the ocean bottom.
- Genetics
Benyam Kinde: Gene expression and Rett syndrome
M.D.-Ph.D. student Benyam Kinde studies how genetic changes affect brain cells’ activity in Rett syndrome.
- Health & Medicine
Isaac Kinde: Finding cancer via altered genes
Isaac Kinde helped create a technology that can spot cancers early to give patients a better chance at survival.
- Neuroscience
Priya Rajasethupathy: Memories mark DNA
Neuroscientist Priya Rajasethupathy has discovered a tiny molecule that may turn off part of the genome to help the brain store long-term memories.
- Neuroscience
Steve Ramirez: Erasing fear memories
Neuroscientist Steve Ramirez is manipulating memories in mice to one day erase fearful memories of PTSD.
