Engineers uncover why tiny particles form clusters in turbulent air

Tiny solid particles—like pollutants, cloud droplets and medicine powders—form highly concentrated clusters in turbulent environments like smokestacks, clouds and pharmaceutical mixers.

What causes these extreme clusters—which make it more difficult to predict everything from the spread of wildfire smoke to finding the right combination of ingredients for more effective drugs—has puzzled scientists.

A University at Buffalo study, published in Proceedings of the National Academy of Sciences, suggests the answer lies within the electric forces between particles.

Advanced AI links atomic structure to quantum tech

A research team led by Oak Ridge National Laboratory has developed a new method to uncover the atomic origins of unusual material behavior. This approach uses Bayesian deep learning, a form of artificial intelligence that combines probability theory and neural networks to analyze complex datasets with exceptional efficiency.

The technique reduces the amount of time needed for experiments. It helps researchers explore sample regions widely and rapidly converge on important features that exhibit interesting properties.

“This method makes it possible to study a material’s properties with much greater efficiency,” said ORNL’s Ganesh Narasimha. “Usually, we would need to scan a large region, and then several small regions, and perform spectroscopy, which is very time-consuming. Here, the AI algorithm takes control and does this process automatically and intelligently.”

Psychedelic medicine could revolutionise how we treat mental illness

Depression, anxiety, PTSD and other maladies of the mind are plaguing our societies. Our medicines are now decades old, and their effectiveness is questionable. Around half of those taking antidepressants experience no benefits. Side effects are common, and relapse rates when stopping the pills can reach 80%.

If someone told you we have a remedy with nearly no relapse, no long term side effects, and life-altering potential, wouldn’t you be curious?

Enter Dr. Ayla Selamoglu (Newnham 2016). As a Trinity postdoc endorsed by biotechnologist Prof. Christopher Lowe OBE, her research centres on psychedelic medicine and drug development.

Psychedelic medicine has the potential to revolutionise psychiatry. And the revolution is starting here.

Dr. Ayla Selamoglu is an expert on psychedelic medicine. Her work shows how nature’s most mysterious compounds provide new ways to combat mental illness.

Corstasis scores FDA nod for nasal spray treatment, touts sales potential

Forty-two years after approving the potent diuretic Bumex (bumetanide) as both an oral and infused treatment for edema, the FDA has endorsed a new version of the drug to be delivered as a nasal spr | Forty-two years after approving the potent diuretic Bumex (bumetanide) as both an oral and infused treatment for edema, the FDA has endorsed a new version of the drug to be delivered as a nasal spray. The U.S. regulator has signed off on Corstasis Therapeutics’ Enbumyst to relieve the edema associated with congestive heart failure, chronic kidney disease and liver disease.
