Glowing plants reveal immune responses around infection sites via two colors

Researchers at the MRC Laboratory of Medical Sciences (LMS) have developed a new way to make glowing biological reporters more accurate, allowing scientists to track gene activity in living plants over days, weeks and potentially even months and years. The approach could help researchers study how plants respond to disease, pests and environmental stress, while opening the door to similar applications in animal and human disease models.

Study maps the human side of flood risk

When heavy rain hits a city, knowing where water will accumulate is only part of the picture. Who lives in the affected buildings? How might flooding disrupt their lives? And where could additional support make the greatest difference?

Christina Applegate misdiagnosis: Why can MS be difficult to diagnose?

Actor Christina Applegate was diagnosed with multiple sclerosis (MS) over five years ago — but this week, she announced that a recent reevaluation found that she doesn't have the condition after all. In the wake of that revelation, she's been left without a diagnosis, and she said on a podcast that she felt she was "back at square one, where I don't know what's going on with me."Applegate's case is not totally unique, although MS diagnosis has improved over the years. Studies offer different estimates of how frequently MS is misdiagnosed, with rates ranging from 5% to over 40%, depending on the patient population and clinical setting. There is also some degree of underdiagnosis — cases in wh...

Scientists demonstrate AI-designed enzyme for drug synthesis

The new RFD4-Proteina unified generative model for protein design—created by the Institute for Protein Design (IPD) in collaboration with NVIDIA—uses advanced AI to generate entirely new protein sequences and structures, achieving computational design success rates five to 10 times higher than previous models and generating candidates five to 10 times faster.

Elections are more predictable than they look

As politics in America become more polarized and each voting cycle seems more fraught than the last, a common narrative in the media is that each election is unique and increasingly unpredictable. But new research shows that congressional elections follow strong statistical patterns, even when individual races produce surprises.

Bacteria reinvent their weapons through selection, chance and gene swapping

Many of the most potent antibiotics originate from bacteria. A large proportion belong to a class of compounds known as nonribosomal peptides (NRP). They are produced by large bacterial enzyme machineries—the nonribosomal peptide synthetases, or NRPS for short. These function like molecular assembly lines: Similar to the stations in a car factory, where new parts are added to the car at each step, several specialized modules string together amino acid by amino acid to build a peptide.

New marker panel and free web tool help track stem cells as they develop

How can the identity of pluripotent stem cells be determined more reliably during their differentiation? Researchers from the IUF—Leibniz Research Institute for Environmental Medicine and Heinrich Heine University Duesseldorf have systematically validated marker genes for this purpose and developed a web-based application for the automated classification of early cell fates. The study has been published in Stem Cell Reports.

Can we stop antibiotic resistance from ruining promising drugs before they reach patients?

What if we could predict early in drug development which antibiotics bacteria are most likely to become resistant to? In a review published in Nature Reviews Microbiology, researchers from the HUN-REN Biological Research Centre, Szeged (HUN-REN BRC Szeged) and the Hungarian Centre of Excellence for Molecular Medicine (HCEMM) in Szeged propose a five-step decision-making framework that could help identify resistance risks early, refine promising drug candidates and prevent costly failures.

Stellar collision may explain why Orion Nebula's planet-forming disks appear younger than its stars

The Orion Nebula is a large star-forming region visible to the naked eye. Some of the young stars in the nebula are surrounded by disks of gas and dust in which planets form. Radiation from the massive central star, 1 Ori C1 (Theta-1 Orionis C1), gradually strips material from these disks, giving them shapes that resemble tadpoles.

Scientists uncover the molecular pillars that shape our cells' powerpacks

Mitochondria are the tiny powerpacks that supply most of the energy our cells need. Their ability to generate this energy relies on a distinctive architecture: two membranes, one tucked inside the other, separated by a narrow gap called the intermembrane space (IMS). This tiny space helps sustain the chemistry of energy production, making its organization critical to how these cellular powerpacks function.
