A recent study led by Evan Forman, PhD, a psychology professor in Drexel University's College of Arts and Sciences, shows that a computer game can be used to train its players to eat less sugar, as way of reducing their weight and improving their health.
An ancient human foraging instinct, fueled by fructose, may hold clues to the development of Alzheimer’s disease, according to researchers.
In the late 1980s, there were near a million new cases of guinea worm disease recorded worldwide. In 2021, there were only 15. How was this achieved?
A next-generation COVID-19 mucosal vaccine is set to be a gamechanger not only when delivering the vaccine itself, but also for people who are needle-phobic.
If I asked you to name the most common chronic disease in children, what would you say? Asthma comes top of mind, but there is something five times more common in kids: cavities. We don’t typically think of dental cavities as a chronic disease—in part because of the separation between medicine and dentistry—but it is…
Observations in mice hint at role of daydreams in remodeling the brain
This week Matt Brauer is back to describe work he did to analyze the trajectory of the Hyperloop proposal. This is a key input to the Hyperloop Simulink models we are building. Matt's conclusion is surprising: From the perspective of geographic constraints and rider comfort, the 760 mph peak speed is not an issue…
J. Nicholas Betley has led collaborative research seeking the neural basis of long-term sustained pain and finds that a critical hub in the brainstem holds a mechanism for stopping pain signals from reaching the rest of the brain. Their findings could help clinicians better understand chronic pain and lead to new…
Koko the gorilla is best known for a lifelong study to teach her a silent form of communication, American Sign Language. But some of the simple sounds she has learned may change the perception that humans are the only primates with the capacity for speech.
Fructose is a sweetener added to ultra-processed foods, typically in the form of high-fructose corn syrup. WashU research shows that the liver turns fructose into lipids that many types of cancers crave.

Over the past year, three people with paralysis have received Neuralink implants. This blog post explores how each person is using Telepathy in everyday life.
In healthy adults, meals matched for calories and nutrients, but otherwise prepared differently, led to unexpectedly different metabolic responses and activity in the brain’s reward system.
In April 1986, following an attack on American soldiers in a Berlin disco, President Reagan ordered the bombing of Muammar Qaddafi's terrorist camps in Libya. My duty was to fly over Libya and take photos recording the damage our F-111's had inflicted. Qaddafi had established a 'line of death,' a territorial marking…

UBC scientists create device that uses wood dust to trap up to 99.9 per cent of microplastics in water.
An international research team, including Jonathan C. Schisler, PhD, in the UNC School of Medicine, has found how SARS-CoV-2 causes widespread “energy outages” throughout major organs, and how these effects contribute to debilitating long COVID symptoms.

Neuroscientists at the Picower Institute for Learning and Memory at MIT have discovered that when a synapse strengthens, neighboring synapses weaken based on the action of a crucial protein called Arc. The finding provides an explanation of how synaptic strengthening and weakening combine in neurons to produce…
Today is a doubly important day: it marks the final day of the PEARL campaign and it is a celebration of another victory for the life extension community.
The Wildlife Trusts congratulate the UK Government’s decision to open the door for licenced reintroductions of beavers into the wild and its acknowledgment of the free-living populations in several parts of England.
