Possible death of the universe scenario proposed

A new theory suggests that a dynamical system singularity may not be a physical reality, allowing the universe to evolve infinitely. The study, published in Physical Review D, proposes an alternate gravity model that includes quadratic scalar invariants and corresponds with Alexei Starobinsky's inflational theory.

How number crunching can optimize crisp frying

A team of mathematicians from around the world collaborated to solve real-world problems faced by industry. By applying mathematical models to the manufacture of stackable fabricated potato chips, they aimed to predict cooking times, optimize chip position, and improve the overall efficiency of the process.

Greater market liquidity actually increases risk, according to Ben-Gurion University researchers

The study shows that increased liquidity leads to a more volatile appetite for risk in the market, causing all stocks to become more risky. This volatility affects the Sharpe ratio, which measures excess return for additional risk, ultimately making investors need compensation for taking on higher-risk assets.

A breath test for early-stage Parkinson's

Researchers developed a sensor to detect early-stage Parkinson's disease from patient breath, achieving 79% sensitivity and 84% specificity. The device detected differences in the exhaled breath of newly diagnosed patients, outperforming diagnostic smell tests and ultrasound scans.

Easy-Bake fossils

Researchers at Field Museum create 'Easy-Bake fossils' by simulating the fossilization process in a lab, allowing for more accurate interpretations of ancient organisms. The method enables scientists to study the preservation of soft tissues and biomolecules, shedding light on evolution and biology.

Multi-disease health fairs, 'test and treat' help E. African communities achieve HIV goals

Rural East African communities that hosted annual health fairs saw higher overall survival and viral suppression rates compared to standard care. Annual multi-disease health fairs delivered patient-centered, streamlined HIV care, resulting in fewer new HIV cases, better control of hypertension and diabetes, and lower TB rates.

Antibacterial glass ionomer cement with chlorhexidine-encapsulated mesoporous silica

Researchers developed a novel antibacterial glass ionomer cement with chlorhexidine-encapsulated mesoporous silica, which significantly enhances anti-biofilm ability and maintains mechanical properties. The study proposes a new strategy for preventing secondary caries by using this modified GIC.

Multiple pregnancies might make women's cells 'age' faster

A Northwestern University study suggests that multiple pregnancies can lead to accelerated biological aging in women, as measured by telomere length and epigenetic age. Women with more pregnancies showed signs of faster cellular aging, even when currently pregnant, which challenges the idea that pregnancy itself makes women look younger.
