A new neural network makes decisions like a human would
2024-07-15
Humans make nearly 35,000 decisions every day, from whether it’s safe to cross the road to what to have for lunch. Every decision involves weighing the options, remembering similar past scenarios, and feeling reasonably confident about the right choice. What may seem like a snap decision actually comes from gathering evidence from the surrounding environment. And often the same person makes different decisions in the same scenarios at different times.
Neural networks do the opposite, making the same decisions each time. Now, Georgia Tech researchers in Associate Professor Dobromir Rahnev’s lab are ...

You're just a stick figure to this camera
2024-07-15
Images
A new camera could prevent companies from collecting embarrassing and identifiable photos and videos from devices like smart home cameras and robotic vacuums. It's called PrivacyLens and was made by University of Michigan engineers.
PrivacyLens uses both a standard video camera and a heat-sensing camera to spot people in images from their body temperature. The person's likeness is then completely replaced by a generic stick figure, whose movements mirror those of the person it stands in for. The accurately animated stick figure allows a device relying on the ...

How does superglue work, and what the heck is electroadhesion? (video)
2024-07-15
WASHINGTON, July 15, 2024 — How would you stick a slice of banana to a sheet of copper? Until a few months ago, you couldn’t. But a new discovery called “hard-soft electroadhesion” enables chemists to stick almost any hydrogel to almost any metal, using nothing but an electric current. And you can unstick the materials simply by reversing the current. Recently reported in ACS Central Science, this astonishingly general phenomenon works with a wide variety of gels (including fruits, vegetables, meat and fish) and conductors (including metals and graphite). Join our host George as he attempts to replicate electroadhesion in his basement ...

Tell-tale gene affects success of drug used to treat chronic pain
2024-07-15
Women who carry a particular form of a pain gene are more likely to respond well to a common medication used to treat long-term discomfort, research shows.
In a study, women with chronic pelvic pain who had a naturally occurring variation of a gene, known as Neuregulin 3, in their DNA were more likely to experience relief after taking the painkilling drug gabapentin.
Targeting gabapentin use to those with this genetic marker would avoid ineffective treatment and unwanted side-effects in those who are unlikely to respond, experts say.
The findings could improve use of gabapentin in treating chronic pelvic pain – a persistent, disabling ...
Study reveals how an anesthesia drug induces unconsciousness
2024-07-15
There are many drugs that anesthesiologists can use to induce unconsciousness in patients. Exactly how these drugs cause the brain to lose consciousness has been a longstanding question, but MIT neuroscientists have now answered that question for one commonly used anesthesia drug.
Using a novel technique for analyzing neuron activity, the researchers discovered that the drug propofol induces unconsciousness by disrupting the brain’s normal balance between stability and excitability. The drug causes brain activity to become increasingly unstable, until the brain loses consciousness.
“The brain has to operate on this knife’s ...

A stochastic modeling approach for interplanetary supply chain planning
2024-07-15
First of all, the problem scope and the theoretical foundation are presented. The considered ISC network is a layered network in which nodes represent points of interactions between the two layers. The two interacting networks are PN which delivers cargo from Earth to Mars and SN that is responsible for the propellant supply along the way, respectively. They share the same nodes but comprise different arcs based on their distinct purposes. The nodes are defined as surface nodes (celestial bodies ...
When certain boys feel their masculinity is threatened, aggression ensues
2024-07-15
It’s been long established that certain men become aggressive when they see their manhood as being threatened. When does this behavior emerge during development—and why? A new study by a team of psychology researchers shows that adolescent boys may also respond aggressively when they believe their masculinity is under threat—especially boys growing up in environments with rigid, stereotypical gender norms.
The findings, reported in the journal Developmental Science, underscore the effects of social pressure that many boys face to be stereotypically masculine.
“We know that not all men respond aggressively to manhood threats—in ...

Study pinpoints origins of creativity in the brain
2024-07-15
Have you ever had the solution for a tough problem suddenly hit you when you’re thinking about something entirely different? Creative thought is a hallmark of humanity, but it’s an ephemeral, almost paradoxical ability, striking unexpectedly when it’s not sought out.
And the neurological source of creativity—what’s going on in our brains when we think outside the box—is similarly elusive.
But now, a research team led by a University of Utah Health researcher and based in Baylor College of Medicine has used a precise method of brain imaging to unveil how different parts of the brain ...

30-year risk of cardiovascular disease may help inform blood pressure treatment decisions
2024-07-15
Research Highlights:
A comparison of two tools for calculating cardiovascular disease risk found that if only the current 10-year risk thresholds are applied, fewer adults may be recommended for blood pressure-lowering medication. The tools, The American Heart Association’s new PREVENTTM tool and the Pooled Cohort Equations, were applied to a cross-sectional sample of adults from NHANES datasets with stage 1 hypertension who did not report having CVD.
PREVENT can additionally be used to calculate an individual’s 30-year risk ...
