Heart patch produced from induced pluripotent stem cells derived heart muscle cells in a collagen hydrogel

For the 99%, allografts can patch up failing heart

Jan. 29, 2025
By Anette Breindl
Implanted patches of iPS-derived heart muscle integrated with heart tissue in a primate model of heart failure, and in patients being treated in a clinical trial, marks progress toward a potential option for patients with advanced heart failure.

Neurons send immune cells to the pancreas to regulate glucose

Jan. 27, 2025
By Mar de Miguel
The liver and pancreas are the main actors in glucose metabolism, but not the only ones. Muscles, adipose tissue and the brain play different roles. However, the prize for the best new actor in glucagon production goes to the innate lymphoid cells (ILCs), which, according to a study published in Science, respond to intestine neuron signals traveling to the pancreas to control glucose.

An antidote to cobra venom designed with AI

Jan. 22, 2025
By Mar de Miguel
Following Nobel Prize-winning chemist David Baker’s recipe for cooking an antidote to cobra venom using artificial intelligence (AI) could be faster and more effective than currently available methods. The ingredients and steps can be found in a new study published by the University of Washington scientist in collaboration with the Technical University of Denmark. They are ready for the next steps in preclinical trials.

New drugs with the same old resistance tricks?

Jan. 21, 2025
By Coia Dulsat
According to the World Health Organization (WHO), multidrug-resistant pathogens caused over 1.27 million deaths worldwide in 2020. And figures are rising, with projections pointing to antimicrobial resistance surpassing cancer as the leading cause of death by 2050. Now, researchers at the HUN-REN Biological Research Center have unveiled the role of pre-existing genetic variabilities and specific cross-resistance patterns among several antibiotics designed to combat gram-positive bacteria.

Map is first step toward healthy brains into old age

Jan. 14, 2025
By Anette Breindl
2024 saw the completion of several cellular-resolution brain maps, including the entire fly brain and a comprehensive connections map of a cubic centimeter of human brain. 2025 began with the addition of another important map. In the Jan. 1, 2025, issue of Nature, researchers from the Allen Institute presented a map of areas and cell types where aging most affected the mouse brain.

Human, mouse PD-1 differ inside and out

Jan. 10, 2025
The PD-1 receptor, a major immune checkpoint inhibitor whose signaling is the target of multiple blockbuster anticancer drugs, differs functionally between rodents and humans in previously unknown ways. Researchers from the University of California, San Diego, and co-authors at the Chinese Academy of Sciences and the National Cancer Institute reported these findings in the Jan. 3, 2025, online issue of Science Immunology.

Progress in cancer research, even the toughest types

Jan. 2, 2025
By Mar de Miguel and Anette Breindl
Among the most profound results presented at the 2024 European Society for Medical Oncology Congress were the 10-year data from the Checkmate-067 and Keynote-006 trials of Opdivo and Keytruda as first-line agents in advanced or metastatic melanoma in which 10-year overall survival topped 40%. The success of checkpoint blockade, however, has not extended to all tumor types, but in 2024, molecular studies have led to advances in gene therapies and a multitude of approaches that have opened the door to hope.

The map for a journey to the center of the brain

Dec. 24, 2024
By Mar de Miguel
In the 1970s, scientists from several countries proposed to reconstruct, one by one, all the neurons in the brain as they appear under an electron microscope. They started with a small worm. Caenorhabditis elegans has only 302 neurons. It took 16 years. How much time would be required to repeat this arduous task for the 100 billion neurons in the human brain?
