Limited evidence suggests calorie restriction may slightly reduce depressive symptoms in people with elevated cardiometabolic risk

A systematic review and meta-analysis evaluated the effects of dietary interventions on depression and anxiety in adults. The review found that calorie restrictive and low-fat diets may reduce depression symptoms in those with high cardiometabolic risk, but the certainty of these findings are low. Evidence on other diets, comparisons of diets to active interventions, and other outcomes is limited, prompting researchers to recommend further exploration in areas including the add-on effect of dietary intervention alongside first-line treatment for depression and/or anxiety. The study is published in Annals of Internal Medicine.
Researchers from Bond University in Queensland reviewed data from 25 randomized controlled trials (RCTs) involving over 57,00 adults evaluating the effect of dietary advice with or without food provision compared with usual eating habits. on depression and/or anxiety for at least three months. The diets studied in the RCTs included calorie restriction, low-fat diets, and Mediterranean-style diets. The primary outcome was change in depression and/or anxiety severity, and secondary outcomes included incidence of depression and anxiety and quality of life (QoL). The researchers found that compared with usual care, calorie restriction and a low-fat diet may reduce depressive symptoms in adults with elevated cardiometabolic risk, however, their effect on anxiety is uncertain. Compared with other diets, low-fat diets may lower anxiety, but the evidence is uncertain for its effect on depression. The evidence is also uncertain of the effect of a Mediterranean-style diet on depression, anxiety and QoL compared with no specific dietary advice. Overall, while calorie restriction and low-fat diets could reduce depressive symptoms in certain groups, the researchers had low confidence in the findings and recommend patients discuss any dietary changes with a health care professional before implementing changes.

U of A researchers developing world's first petahertz-speed phototransistor in ambient conditions
2025-05-19
What if ultrafast pulses of light could operate computers at speeds a million times faster than today's best processors? A team of scientists, including researchers from the University of Arizona, are working to make that possible.
In a groundbreaking international effort, researchers from the Department of Physics in the College of Science and the James C. Wyant College of Optical Sciences demonstrated a way to manipulate electrons in graphene using pulses of light that last less than a trillionth of a second. By leveraging a quantum effect known as tunneling, they recorded electrons bypassing a physical barrier almost instantaneously, a feat that redefines the ...
NRL hosts Innovation Day for Industry
2025-05-19
WASHINGTON, D.C. — The U.S. Naval Research Laboratory (NRL) hosted Innovation Day for Industry, May 7, at NRL-DC headquarters to inform industry and to assess interest in a focused set of six emerging technologies that are ready for collaboration with industry partners.
The event showcased a range of NRL-developed technologies ready for further development, prototyping and commercialization through partnerships with industry. The nearly 30 industry attendees gained valuable insights into NRL’s research and development efforts, including presentations, facility tours, and networking opportunities with NRL scientists, ...
Here comes the boom! Studying the effects of rocket launch sonic booms on neighboring communities #ASA188
2025-05-19
NEW ORLEANS, May 19, 2025 – Rocket launches are amazing spectacles, but close-up viewers know to bring a set of earplugs or earmuffs to protect their hearing. However, the boom of a launch isn’t reserved for those who sign up to watch it – it can also be heard and felt in surrounding communities.
SpaceX’s Falcon 9 is a rocket used for both human and nonhuman space missions. Since 2010, the rocket has been launched over 400 times, and one of the launch sites for Falcon 9 is the Vandenberg Space Force Base in California.

Researchers capture brain activity with imager that is smaller than an eyelash
2025-05-19
WASHINGTON — Researchers have developed an extremely thin, flexible imager that could be useful for noninvasively acquiring images from inside the body. The new technology could one day enable early and precise disease detection, providing critical insights to guide timely and effective treatment.
“As opposed to existing prohibitively large endoscopes made of cameras and optical lenses or bulky fiber optic bundles, our microimager is very compact,” said research team leader Maysam Chamanzar from Carnegie Mellon University. “Much thinner than a typical eyelash, ...
A head and a hundred tails: how a branching worm manages reproductive complexity
2025-05-19
Scientists have uncovered the genetic underpinnings of one of the ocean’s most bizzare animals: a branching marine worm named Ramisyllis kingghidorahi that lives inside sea sponges and reproduces in a truly extraordinary way. Living hidden in tropical waters, this worm grows multiple body branches within a host sponge, each tail capable of producing separate living reproductive units called “stolons”. But how does a single animal coordinate sexual reproduction across so many branches? To find out, researchers led by the University of Göttingen analysed gene expression across different body regions and between male, female ...
Investment risk for energy infrastructure construction is highest for nuclear power plants, lowest for solar
2025-05-19
Between now and 2050, the International Energy Agency projects that more than $100 trillion will be spent on building net-zero energy infrastructure globally. Yet every single one of these projects runs the risk of higher-than-expected construction costs or time delays. Newer technologies introduced in the past decade, such as hydrogen or geothermal energy, are even more difficult to evaluate as government agencies, energy developers, utilities, investors, and other stakeholders decide which sustainable energy systems are best for future projects.
In a new state-of-the-art ...
Personality traits influence the development of insomnia
2025-05-19
A study conducted at the Faculty of Medicine of the University of São Paulo (USP) in Brazil examined the influence of personality traits on the development and perpetuation of insomnia and found that there is a direct relationship between the two. Two findings caught the researchers’ attention: high levels of openness were associated with low levels of insomnia, while high levels of neuroticism (characterized by emotional instability) were very common in people with the sleep disorder. The results were published in the Journal of Sleep Research.
“We decided ...
Controlling these 8 risk factors may eliminate early death risk for those with high blood pressure
2025-05-19
A new study led by researchers at Tulane University suggests that people with high blood pressure can significantly reduce — and possibly eliminate — their increased risk of premature death by controlling several key health risk factors at once.
The study, published in Precision Clinical Medicine, tracked more than 70,000 people with hypertension and over 224,000 without it, using data from the UK Biobank. Researchers followed participants for nearly 14 years to understand how managing these risk factors affected early mortality — ...

2025-05-19
The 21st edition of Sustainability Through Science and Technology Summit 2025 (SIPS 2025), dedicated to Prof. Aaron Ciechanover, Nobel Laureate in Chemistry, to be held in Cebu, Philippines, from 17-20 November 2025, has confirmed the participation of Davis Joseph as an invited summit plenary lecturer for his recent ground-breaking discovery of the common master switch for numerous brain-related diseases.
Davis Joseph discovered something that could not be found in the entire scientific history of Alzheimer’s and Parkinson’s research: a common master switch that can potentially cure both these and other brain-related diseases ...
Novel data streaming software chases light speed from accelerator to supercomputer
2025-05-19
Analyzing massive datasets from nuclear physics experiments can take hours or days to process, but researchers are working to radically reduce that time to mere seconds using special software being developed at the Department of Energy’s Lawrence Berkeley and Oak Ridge national laboratories.
DELERIA — short for Distributed Event-Level Experiment Readout and Integrated Analysis — is a novel software platform designed specifically to support the GRETA spectrometer, a cutting-edge instrument for nuclear physics experiments. The Gamma Ray Energy Tracking Array, or GRETA, ...
