Stem cell engineering breakthrough paves way for next-generation living drugs

2026-01-08

For the first time, researchers at the University of British Columbia have demonstrated how to reliably produce an important type of human immune cell—known as helper T cells—from stem cells in a controlled laboratory setting. The findings, published today in Cell Stem Cell, overcome a major hurdle that has limited the development, affordability and large-scale manufacturing of cell therapies. The discovery could pave the way for more accessible and effective off-the-shelf treatments for a wide range of conditions like ...

California grants $7.4 million to advance gene-edited stem cell therapy for Friedreich’s ataxia

2026-01-08

The California Institute for Regenerative Medicine (CIRM) has awarded $7.4 million to support a University of California San Diego team developing a first-of-its-kind stem cell-based gene therapy for Friedreich’s ataxia, a rare inherited neurodegenerative disease that causes progressive loss of coordination, muscle strength, heart function and overall mobility. The new funding will help the research team complete the final steps required by federal regulators before they can apply to begin a first-in-human clinical trial. “This support is essential for scientific progress and for families living ...

Victoria’s Secret grant backs cutting-edge ovarian cancer research

2026-01-08

Promising ovarian cancer research by Melanie Rutkowski, PhD, at the University of Virginia Comprehensive Cancer Center has won $700,000 in support from the Victoria’s Secret Global Fund for Women’s Cancers in partnership with Pelotonia and AACR, the American Association for Cancer Research. Rutkowski has been selected as a Victoria’s Secret Rising Innovator, receiving a Research Grant in partnership with Pelotonia and AACR to further her studies of the role of the microbiome – the collection of microorganisms that live within ...

Research paves the way for safer colonoscopy bowel prep for people with compromised gut health

2026-01-08

New preclinical research suggests that bowel preparation procedures for colonoscopies may temporarily alter gut balance, culminating in unappreciated effects in patients with compromised gastrointestinal health. The study, published in Cell Reports Medicine, found that simulating bowel preparation in mouse models disrupted the gut environment, making the mice more susceptible to infection and inflammation. "Colonoscopies play a crucial role in the diagnosis and treatment of gastrointestinal pathologies, including cancer, so it’s important to emphasize that we’re not trying ...

JMIR Publications and Sweden's National Library announce renewal and expansion of flat-fee unlimited open access partnership for 2026

(Toronto & Stockholm, January 7, 2026) JMIR Publications, a leading open-access digital health research publisher, and the National Library of Sweden (NLS), representing the Bibsam Consortium, are pleased to announce the extension of their Flat-Fee Unlimited Open Access Publishing Agreement through December 31, 2026. The renewal of this agreement, originally set to expire on December 31, 2025, reinforces the commitment of Swedish research funders and institutions to the principles of open science. The partnership provides authors affiliated with ...

A new 3D-printed solar cell that’s transparent and color-tunable

2026-01-08

A new study highlights a semi-transparent, color-tunable solar cell designed to work in places traditional panels can’t, like windows and flexible surfaces. Using a 3D-printed pillar structure, the researchers can fine-tune how much light passes through and what color the cell appears, without changing the solar material itself. The result is a system that balances energy output with durability, while giving designers far more control over how the technology looks and functions. [Hebrew University of Jerusalem] The research was led by Prof. Lioz Etgar and Prof. Shlomo Magdassi and from the Institute of Chemistry and the Center for Nanoscience and Nanotechnology ...

IV iron is the cost-effective treatment for women with iron deficiency anemia and heavy menstrual bleeding

2026-01-08

(WASHINGTON, Jan. 8, 2026) — A single dose of intravenous (IV) iron dextran is the cost-effective treatment for women with heavy menstrual bleeding and iron deficiency anemia (IDA), according to new research published in Blood Advances. “Oral iron is usually given as first-line treatment because on the surface, it appears less expensive and more convenient,” said study author Daniel Wang, a fourth-year medical student at Yale School of Medicine currently pursuing a research year as a recipient of the American Society of Hematology Medical Student Physician-Scientist Award. “However, we found that the preferred first-line treatment for these patients ...

Doing good pays off: Environmentally and socially responsible companies drive value and market efficiency

2026-01-08

Fukuoka, Japan—This year marks the 20th anniversary of the Principles for Responsible Investment (PRI), launched with United Nations backing in 2006. Today, environmental, social, and governance (ESG) related non-financial information—such as greenhouse gas emissions, pollution control, and diversity metrics—is routinely analyzed alongside traditional financial data. As companies scale up their ESG commitments, core questions remain: do these efforts create extra value, and how do they ...

City of Hope and Cellares to automate manufacturing of solid tumor CAR T cell therapy

2026-01-08

Collaboration focuses on City of Hope’s IL13RA2-EGFR targeting CAR T cell program addressing a type of fast-growing, aggressive brain cancer called glioblastoma multiforme. The collaboration addresses solid tumor manufacturing bottlenecks and accelerates advancement toward clinical trials. Los Angeles and South San Francisco, Calif. – City of Hope®, one of the largest and most advanced cancer research and treatment organizations in the United States, and Cellares, the first Integrated Development and Manufacturing Organization (IDMO), today announced a ...

Short-circuiting pancreatic cancer

2026-01-08

Pancreatic ductal adenocarcinoma (PDAC) is the most lethal form of pancreas cancer. It’s also the most common form of the disease. Potential treatments typically target a key mutated oncogene called KRAS. In some cases, PDAC tumors with these mutations have resisted therapeutic efforts. However, combination therapies involving alternative drug targets may one day help clinicians overwhelm these defenses. In 2023, Cold Spring Harbor Laboratory (CSHL) Professor Adrian Krainer’s lab discovered ...
