Morning vs bedtime dosing and nocturnal blood pressure reduction in patients with hypertension

JAMA Network Open

2025-07-09

(Press-News.org) About The Study: In this randomized clinical trial of antihypertensive chronotherapy, bedtime dosing provided better control of nocturnal blood pressure and improved the circadian rhythm, without reducing the efficacy on mean daytime or 24-hour blood pressure, or increasing the risk of nocturnal hypotension. These findings support the potential advantages of bedtime administration and offer new evidence to guide future research on antihypertensive chronotherapy.

BMI in children before, during, and after the COVID-19 pandemic

2025-07-09

About The Study: This cross-sectional study including 426,000 children in Denmark found that body mass index (BMI) outcomes of COVID-19 pandemic–related control policies and restrictions were not exclusively observed among children with obesity, which suggests that pandemic-related mitigation policies targeting children and adolescents in all BMI categories are warranted. The findings of this study highlight differences among children of varying ages and BMI classes. Corresponding Author: To contact ...

Branching out: Tomato genes point to new medicines

2025-07-09

Picture juicy red tomatoes on the vine. What do you see? Some tomato varieties have straight vines. Others are branched. The question is why. New research from Cold Spring Harbor Laboratory (CSHL) provides the strongest evidence to date that the answer lies in what are called cryptic mutations. The findings have implications for agriculture and medicine, as they could help scientists fine-tune plant breeding techniques and clinical therapeutics. Cryptic mutations are differences in DNA that don’t affect physical traits unless certain other genetic changes occur at the same time. CSHL Professor & HHMI Investigator Zachary Lippman has ...

Charité study analyzes 400 million years of enzyme evolution

2025-07-09

Enzymes catalyze chemical reactions in organisms - without which life would not be possible. Leveraging AlphaFold2 artificial intelligence, researchers at Charité – Universitätsmedizin Berlin have now succeeded in analyzing the laws of their evolution on a large scale. In the journal Nature*, they describe the parts of enzymes that change comparatively quickly and the parts that remain practically unchanged over time. These findings are relevant to the development of new antibiotics, for example. Enzymes resemble ...

Large-scale DNA study maps 37,000 years of disease history

2025-07-09

A research team led by Eske Willerslev, professor at the University of Copenhagen and the University of Cambridge, has recovered ancient DNA from 214 known human pathogens in prehistoric humans from Eurasia. The study shows, among other things, that the earliest known evidence of zoonotic diseases – illnesses transmitted from animals to humans, like COVID in recent times – dates back to around 6,500 years ago, with such diseases becoming more widespread approximately 5,000 years ago. It is ...

Results from largest review of its kind on antidepressant withdrawal symptoms

2025-07-09

The largest review of ‘gold standard’ antidepressant withdrawal studies to date has identified the type and incidence of symptoms experienced by people discontinuing antidepressants, finding most people do not experience severe withdrawal. In a systematic review and meta-analysis of previous randomised controlled trials relating to antidepressant withdrawal, a team of researchers led by Imperial College London and King’s College London concluded that, while participants who stopped antidepressants did experience an average of one more symptom than those who continued or were taking ...

Twist to the M-ax(is): New twist platform opens path to quantum simulation of more exotic states of matter

2025-07-09

Twisted materials—known as moiré structures—have revolutionized modern physics, emerging as today's "alchemy" by creating entirely new phases of matter through simple geometric manipulation. The term "moiré" may sound familiar—it describes the strange rippling patterns you sometimes see when photographing striped shirts or screens; in physics, the same underlying principle applies at the atomic scale. Imagine taking two atomically thin sheets of either the same or different materials, stacking them up together, and rotating one layer slightly relative ...

Chang'e-6 samples unlock secrets of the Moon’s farside

2025-07-09

The Moon's near and far sides exhibit striking asymmetry—from topography and crustal thickness to volcanic activity—yet the origins of these differences long puzzled scientists. China's Chang'e-6 mission, launched on May 3, 2024, changed this by returning 1,935.3 grams of material from the lunar farside's South Pole–Aitken Basin (SPA), the Moon's largest, deepest, and oldest known impact structure, measuring 2,500 kilometers in diameter. The samples arrived on Earth on June 25, 2024. Previous studies indicated that the SPA was formed by a colossal impact approximately 4.25 billion years ago, releasing energy greater than that of a trillion ...

Teaching lasers to self-correct in high-precision patterned laser micro-grooving

2025-07-09

In International Journal of Extreme Manufacturing, a new laser machining method that dynamically adapts its beam shape is proposed to fabricate microgrooves with complex, highly precise cross-sections—some with a root mean square error decreased to less than 0.5 μm when processing microgrooves with a width of 10 μm. The technique, developed by researchers at the Southern University of Science and Technology (SUSTech) in Shenzhen, China, could advance the production of microfluidic devices, sensors, and heat dissipation systems by allowing for rapid and scalable manufacturing of custom microstructures. Laser micromachining has long been constrained by the fundamental ...

EGFR-targeted therapy resistance in breast and head & neck cancers

2025-07-09

“By synthesizing current insights on both RTK and non-RTK mediated resistance against anti-EGFR therapies, this review aims to guide future research and improve therapeutic strategies for these cancers.” BUFFALO, NY – July 9, 2025 – A new review was published in Volume 16 of Oncotarget on June 25, 2025, titled “Challenges and resistance mechanisms to EGFR targeted therapies in head and neck cancers and breast cancer: Insights into RTK dependent and independent mechanisms.” Researchers from the University of Cincinnati and Cincinnati ...
