Toxins force construction of ‘roads to nowhere’
Toxins released by a type of bacteria that cause diarrheal disease hijack cell processes and force important proteins to assemble into ‘roads to nowhere,’ redirecting the proteins away from other jobs that are key to proper cell function, a new study h…
Artificial neural networks learn better when they spend time not learning at all
Researchers discuss how mimicking sleep patterns of the human brain in artificial neural networks may help mitigate the threat of catastrophic forgetting in the latter, boosting their utility across a spectrum of research interests.
Rapid fluctuations in oxygen levels coincided with Earth’s first mass extinction
Rapid changes in marine oxygen levels may have played a significant role in driving Earth’s first mass extinction, according to a new study.
New study identifies connection between diabetes medications, multiple sclerosis
A study has found that anti-hyperglycemic medications used to treat Type 2 diabetes resulted in an increased risk of multiple sclerosis for people older than 45, particularly among women.
Looking at oxygen storage dynamics in three-way catalysts
A new isotope labeling and catalyst quenching-based direct visualization technique was developed to explain the oxygen storage and release process in three-way catalysts (TWCs) used in vehicular exhaust treatment systems.
The tilt in our stars: The shape of the Milky Way’s halo of stars is realized
New data throws out the textbook picture of a spherical stellar halo and reinforces a dynamic origin story of two galaxies that collided billions of years ago.
Fruit flies use corrective movements to maintain stability after injury
Fruit flies can quickly compensate for catastrophic wing injuries, researchers found, maintaining the same stability after losing up to 40% of a wing. This finding could inform the design of versatile robots, which face the similar challenge of having …
How ‘2D’ materials expand
Researchers developed a technique to effectively measure the thermal expansion coefficient of two-dimensional materials. With this information, engineers could more effectively and efficiently use these atomically-thin materials to develop next-generat…
Asphaltene changed into graphene for composites
The flash Joule heating process turns asphaltenes, a byproduct of crude oil production, into graphene for use in composite materials.
Can pharmacotherapies prevent alcohol use disorder in people with PTSD?
A research team showed how drugs can reduce alcohol preference in animal models of post-traumatic stress disorder.
‘Butterfly bot’ is fastest swimming soft robot yet
Inspired by the biomechanics of the manta ray, researchers have developed an energy-efficient soft robot that can swim more than four times faster than previous swimming soft robots. The robots are called ‘butterfly bots,’ because their swimming motion…
Dietary change starves cancer cells, overcoming treatment resistance
A dietary change could be a key to enhancing colon cancer treatment, a new study finds. Researchers found in cells and in mice that a low-protein diet blocked the nutrient signaling pathway that fires up a master regulator of cancer growth.
