Going with the flow?

Researchers have made significant strides in measuring preferential flow, a crucial factor in soil's physical, chemical, and biological functions. The study reveals unique water patterns depending on landform units, soil types, initial moisture, and precipitation features.

Fat signals control energy levels in the brain

The study found that a key enzyme produced by fat tissue regulates brain function and energy levels, suggesting an optimal amount of body fat for maximizing health and longevity. Mice with low NAMPT in fat tissue had impaired energy levels and physical activity, while those with high NAMPT exhibited increased physical activity.

Heat still on despite warming slowdown

A recent slowdown in global average temperatures is having no effect on the planet's projected warming by 2100. The study found that long-term temperature outcomes are unaffected by short-term variability, with greenhouse gases expected to overwhelm natural fluctuations and lead to dangerous levels of warming.

Thawing permafrost feeds climate change

A recent study found that thawing permafrost in Siberia is releasing ancient carbon into the atmosphere, which is then consumed by microbes and released as carbon dioxide. This process accelerates global warming and creates a runaway effect. Scientists are now studying the impact of this phenomenon on climate change.

Long-term therapy with ETV or TDF demonstrates positive 5-year survival in patients with chronic HBV

A large cohort study found that long-term use of entecavir (ETV) or tenofovir (TDF) results in excellent 5-year survival for Caucasian patients with chronic hepatitis B (CHB), with a significant proportion of deaths coming from liver-unrelated causes. The development of hepatocellular carcinoma plays a major role in mortality.

Looking to fossils to predict tooth evolution in rodents

A new study uses fossil data to predict that most rodent species will evolve continuously growing molar teeth over the next 50 million years. The researchers found evidence that many species possess the potential for acquiring dental stem cells, which are required for continuous tooth growth.

Exploring treatment options for women with fibroids

Women with uterine fibroids have several treatment options, including medical and interventional therapies. Alternative treatment options include tranexamic acid, levonorgestrel-releasing IUDs, hysteroscopic myomectomy, endometrial ablation, gonadotropin-releasing hormone agonists, and more.

The creation of Shangri-La

Researchers used a new computer model to simulate the formation of high-lying valleys in the southeastern Tibetan plateau. They found that these valleys developed in place, not as remnants of former lowlands, and were shaped by river disruption due to tectonic movement.

NEJM perspective: 'Patient CARE Act' Medicaid block grant likely unconstitutional

Two legal experts argue that the proposed Medicaid block grant in the Patient CARE Act would be unconstitutional as it violates the Tenth Amendment. The block grant's fixed sum allocation and limited growth rate would coerce states into accepting a reduced financing structure, similar to the 2012 NFIB v. Sebelius ruling.

Penn researcher advises translational med hubs best place for clinical phenotyping efforts

The article highlights the importance of clinical phenotyping in precision medicine, with Penn researcher Garret FitzGerald advocating for translational med hubs to be equipped with the necessary resources. The NIH's Clinical and Translational Science Awards (CTSAs) program is seen as a key driver of this effort.
