“The nation’s scientific enterprise is being decimated.” That statement in an open letter “to the American people” signed by 1,800 members of the U.S. National Academies, is made concrete in a list of 709 NIH grants – and counting – that have been axed since President Donald Trump was inaugurated on Jan. 20.

Transplanting an animal organ into a human is now a closer reality following the successful xenotransplantation of a genetically modified pig liver into a patient diagnosed with brain death in China. The operation was intended to evaluate organ function over a 10-day period. This is a complex experimental trial that did not involve removing the patient's liver and still requires further study. However, the positive preclinical results suggest this strategy could save the lives of those waiting for a human organ, at least in certain cases.

Science ministers from 13 countries in Europe are calling on the European Union to offer a home to researchers affected by the Trump Administration’s cuts. They have written to EU research and innovation commissioner Ekaterina Zaharieva asking her to organize a welcome “for brilliant talents from abroad who might suffer from research interference and ill-motivated and brutal funding cuts.”

Investigators at Pennsylvania State University have described a novel approach to combat Clostridioides difficile infection using a synthetic microbiome therapy, which offers an alternative to antibiotics and fecal microbiota transplant .

New research has uncovered a complex interplay between extracellular matrix (ECM) structure and the transcriptional responses of cancer cells, showing how they alter their gene expression to ‘escape’ from ECM.

Using ALK+ lung cancer patient-derived cell lines, researchers have performed phosphoproteomic screening and identified guanylate kinase 1 (GUK1) as a TKI sensitive metabolic molecule in ALK-driven lung cancer.

The scientific establishment has launched a fight back against the Trump administration and the slew of executive orders that threaten to dismantle research funding, with a warning that the next month could be critical for the future of U.S. science.

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.

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.

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.
