A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health, including thinking clarity, emotional well-being, and sense of purpose.

A new AI chip works without the cloud server or internet connections needed by existing chips. The AI Pro, designed by Prof Hussam Amrouch, is modelled on the human brain. Its innovative neuromorphic architecture enables it to perform calculations on the spot, ensuring full cyber security. It is also up to ten times more energy efficient. Read more ›

Researchers found that consumers tend to overestimate fractional star ratings and underestimate fractional numerals. In either case, the ratings can be misleading, potentially causing a company to unknowingly overpromise and underdeliver -- or sell its own product short. Read more ›

Postpartum depression (PPD) affects up to 15 percent of individuals after childbirth. Early identification of patients at risk of PPD could improve proactive mental health support. Researchers developed a machine learning model that can evaluate patients' PPD risk using readily accessible clinical and demographic factors. Findings demonstrate the model's promising predictive capabilities. Read more ›

Millions of years of evolution have enabled some marine animals to grow complex protective shells composed of multiple layers that work together to dissipate physical stress. In a new study, engineers have found a way to mimic the behavior of this type of layered material, such as seashell nacre, by programming individual layers of synthetic material to work collaboratively under stress. The new material design is poised to enhance energy-absorbing... Read more ›

New research details how infrared thermography, high-definition imaging and neural network analysis can combine to make concrete bridge inspections more efficient. Researchers are hopeful that their findings can be leveraged by engineers through a combination of these methods to strategically pinpoint bridge conditions and better allocate repair costs.

A new study reveals that a single gene plays a big role in how the liver stores energy, a process that's critical for overall health and for managing diseases like type 2 diabetes. The research focuses on the PPP1R3B gene. This gene tells the liver how to handle energy: store it as glycogen (a form of sugar) or triglycerides (a type of fat). Read more ›

New research suggests that the negative effects of the ozone hole on the carbon uptake of the Southern Ocean are reversible, but only if greenhouse gas emissions rapidly decrease. The study finds that as the ozone hole heals, its influence on the ocean carbon sink of the Southern Ocean will diminish, while the influence of greenhouse gas (GHG) emissions will rise. Read more ›

Researchers have shown in mice that brain cells known as astrocytes are required for a signaling chemical called norepinephrine to modify brain activity, changing the textbook understanding that norepinephrine acts directly on neurons. Read more ›

A groundbreaking new study introduces an AI-powered smartphone app that noninvasively screens for anemia using a photo of a user's fingernail. The study shows the app provides hemoglobin estimates comparable to traditional lab tests, with over 1.4 million tests conducted by 200,000+ users. An estimated 83 million Americans and more than 2 billion people globally are at high risk for anemia -- populations that stand to benefit significantly from this... Read more ›

Researchers have developed a method to confidently produce blood cell precursors from stem cells in mice, by activating a set of seven key genes in the laboratory. The team takes a step forward towards the production of precursor cells able to restore the bone marrow of blood cancer patients, in a successful example of regenerative medicine. Read more ›
