HIV drug can improve vision in patients with common diabetes complication, clinical trial suggests

2025-05-27
An inexpensive, long-approved HIV drug can improve vision in patients with a blinding complication of diabetes more effectively and a much lower cost than many existing treatments, an initial clinical trial suggests. Further, the drug is taken orally, potentially offering patients an alternative to monthly injections directly into their eyes. The drug, lamivudine, could represent an important new option for millions of patients with diabetic macular edema (DME), a condition which causes fluid to build up in the retina of the eye. ...

New fuel cell could enable electric aviation

2025-05-27
Batteries are nearing their limits in terms of how much power they can store for a given weight. That’s a serious obstacle for energy innovation and the search for new ways to power airplanes, trains, and ships. Now, researchers at MIT and elsewhere have come up with a solution that could help electrify these transportation systems. Instead of a battery, the new concept is a kind of fuel cell — which is similar to a battery but can be quickly refueled rather than recharged. In this case, the fuel is liquid sodium metal, an inexpensive and widely available commodity. The other side of the cell is just ordinary air, which serves as ...

Can AI analogize?

2025-05-27
Can large language models (LLMs) reason by analogy? Some outputs suggest that they can, but it has been argued that these results reflect mimicry of the results of analogical reasoning in the models’ training data. To test this claim, LLM’s have been asked to solve counterfactual problems that are unlikely to be  similar to problems in training data sets. Here is an example: Let’s solve a puzzle problem involving the following fictional alphabet: [x y l k w b f z t n j r q a h v g m u o p d i c s e] Here is the ...

AI aversion in social interactions

2025-05-27
An experimental study suggests that people are less likely to behave in a trusting and cooperative manner when interacting with AI than when interacting with other humans.  Scientists use experimental games to probe how humans make social decisions requiring both rational and moral thinking. Fabian Dvorak and colleagues compared how humans act in classic two-player games when playing with another human to how humans act when playing with a large-language model acting on behalf of another human. Participants played the Ultimatum ...

In dry conditions, locust babies are born with their first lunch

2025-05-27
Locusts have undersized babies—with their first lunch already in their guts—in dry conditions. Desert locusts have two distinct modes—solitary and gregarious—that are behaviorally and visibly different. The insects also live in the Sahara desert, an environment with frequent dry conditions. Koutaro Ould Maeno and colleagues explored how a lack of moisture and the presence of other locusts shift reproductive resource allocation in the insects. In lab experiments, the authors raised locusts in crowds and in isolation. Crowd-reared females produced fewer, larger eggs than females raised in ...

Feedback loops between disease and human behavior can produce epidemic waves

2025-05-27
Epidemics of infectious disease often come in waves, but the causes of these waves aren’t clear, frustrating efforts to predict or mitigate them. Are waves of infection caused by transmission seasonality, viral mutations, implementation of public health interventions, or something else? Claus Kadelka and colleagues model how human behavior, in response to information about disease risk, can create waves. There is frequently a lag between infection prevalence and the information about that prevalence reaching the public. Once ...

Results show that the average daily sleep duration of new mothers was 4.4 hours during the first week after giving birth compared with a pre-pregnancy sleep duration of 7.8 hours. Their longest stretch of uninterrupted sleep also fell from 5.6 hours at pre-pregnancy to 2.2 hours in the first week after delivery. Nearly one-third of participants (31.7%) went more than 24 hours without sleep ...

Location matters: Belly fat compared to overall body fat more strongly linked to psoriasis risk

2025-05-27
Philadelphia, May 27, 2025 – Researchers have found that central body fat, especially around the abdomen, is more strongly linked to psoriasis risk than total body fat, particularly in women. This link between central fat and psoriasis remained consistent regardless of genetic predisposition, indicating that abdominal fat is an independent risk factor. The study in the Journal of Investigative Dermatology, published by Elsevier, provides insights that could help improve early risk prediction and guide personalized prevention strategies. Psoriasis is a chronic inflammatory skin condition that can have a significant impact on quality of life. Many individuals with psoriasis also ...
