Researchers develop a rapid method for building vascular organoids

This system offers a powerful new platform for vascular network modeling, tissue engineering, and regenerative medicine

2025-06-13
(Press-News.org) Blood vessels are essential to nearly all tissues, delivering nutrients and oxygen, regulating hemostasis, and modulating inflammation. Recreating functional vascular networks is foundational to both basic and translational vascular biology, however current methods to make blood vessels from stem cells are often slow, inefficient, or lack the complexity needed for therapy.

In this study, researchers developed a fast and defined method to build vascular organoids—3D microvascular networks—from human stem cells. By precisely activating two transcription factors (ETV2 and NKX3.1), they were able to drive the formation of both endothelial and mural cells simultaneously. This resulted in self-assembling, functional vessels that can connect to host vasculature when implanted.

This approach not only accelerates the process of building blood vessels but—critically—achieves full, independent control over the two major vascular cell types needed to build functional blood vessels. This level of control has not been previously demonstrated in other models. As a result, this system offers a powerful new platform for vascular network modeling, tissue engineering, and regenerative medicine.

Cannabis legalization and opioid use disorder in Veterans Health Administration patients

2025-06-13
About The Study: The results of this cohort study suggest that medical cannabis laws and recreational cannabis laws enactment was associated with greater opioid use disorder (OUD) prevalence in Veterans Health Administration patients over time, with the greatest increases among middle-aged and older patients and those with chronic pain. The findings did not support state cannabis legalization as a means of reducing the burden of OUD during the ongoing opioid epidemic.

Volume and intensity of walking and risk of chronic low back pain

2025-06-13
About The Study: In this cohort study, daily walking volume and walking intensity were inversely associated with the risk of chronic low back pain. The findings suggest that walking volume may have a more pronounced benefit than walking intensity.  Corresponding Author: To contact the corresponding author, Rayane Haddadj, MS, email rayane.haddadj@ntnu.no.

New cooling tech could curb data centers' rising energy demands

2025-06-13
Engineers at the University of California San Diego have developed a new cooling technology that could significantly improve the energy efficiency of data centers and high-powered electronics. The technology features a specially engineered fiber membrane that passively removes heat through evaporation. It offers a promising alternative to traditional cooling systems like fans, heat sinks and liquid pumps. It could also reduce the water use associated with many current cooling systems. The advance is detailed in a paper published on June 13 in the journal Joule. As artificial intelligence (AI) and cloud computing continue to expand, the demand for data processing—and ...

First quantum-mechanical model of quasicrystals reveals why they exist

2025-06-13
Photos   A rare and bewildering intermediate between crystal and glass can be the most stable arrangement for some combinations of atoms, according to a study from the University of Michigan.   The findings come from the first quantum-mechanical simulations of quasicrystals—a type of solid that scientists once thought couldn't exist. While the atoms in quasicrystals are arranged in a lattice, as in a crystal, the pattern of atoms doesn't repeat like it does in conventional crystals. The new simulation method suggests quasicrystals—like crystals—are fundamentally ...

Cardiovascular disease and diabetes are driving the increase in us excess mortality—and adults without college degrees are bearing most of the burden

2025-06-13
About 525,000 more deaths occurred among US adults in 2023 than would be expected had pre-2010 mortality trends continued. More than 90 percent of these deaths occurred among individuals without a Bachelor's degree and were largely caused by cardiovascular diseases, underscoring how educational attainment can influence individuals’ health opportunities and outcomes. Cardiometabolic diseases such as cardiovascular disease and type 2 diabetes have emerged as some of the key drivers of worsening mortality rates in the United States over the last ...

Diagnostic value of GeneXpert MTB/RIF in bronchoalveolar lavage fluid for pulmonary non-tuberculosis mycobacterial in acid-fast stain smear-positive and GeneXpert MTB/RIF-negative cases

2025-06-13
Background: The identification of non-tuberculosis (TB) mycobacterial (NTM) infection remains a significant challenge. This study aims to investigate the diagnostic value of multicolour nested real-time fluorescence quantitative nucleic acid amplification detection technology [Xpert Mycobacterium tuberculosis (MTB)/rifampicin (RIF)] in bronchoalveolar lavage fluid (BALF) acid-fast smear-positive cases. Methods: Between 1 January 2017 and 30 June 2022, 365 patients who underwent fibreoptic bronchoscopy and had positive acid-fast ...

Hereditary mutations in BRCA genes increase risk of rare lymphoma among women with breast cancer who received textured breast implants

2025-06-13
(WASHINGTON, June 13, 2025) – Women with breast cancer who were also carriers of the BRCA1 or BRCA2 mutation and received textured breast implants as part of their reconstructive surgery after mastectomy were 16 times more likely to develop breast implant-associated anaplastic large cell lymphoma (BIA-ALCL), a rare T-cell lymphoma, compared with similar women without these genetic mutations, according to a study published today in Blood Advances. “Our findings show that BRCA1 and BRCA2 mutations are a significant risk factor for developing this type of lymphoma, confirming earlier suggestions of a possible role. It’s possible ...
