human cells

A new study published in Nature presents a systematic mapping of functional signaling landscapes across the human phosphoproteome, charting how phosphorylation events regulate cell signalling on a large scale. The work offers researchers a resource for understanding cellular communication and how its disruption may contribute to disease. Reception details are limited so far.

Researchers have published a phosphoproteome atlas of human cell lines in Nature, charting the landscape of kinase activity across widely used laboratory models. The resource documents phosphorylation patterns that indicate which kinases are active in different cell lines, offering scientists a reference for studying cell signalling and for selecting appropriate models in cancer and drug research.

Eric Topol, a prominent American physician-scientist, argues that aging in humans is driven substantially by the loss of cell identity: as cells age, they drift from their specialised roles, which undermines tissue function and contributes to age-related disease. Writing on his Ground Truths platform, he frames this cellular reprogramming as a central mechanism in the biology of aging, a topic of growing interest in longevity research.

The Evening Standard reports on a new frontier in computing: data centres that use lab-grown human brain cells to process information. The technology, often called biocomputing, uses cultivated neurons that can learn and adapt, raising the prospect of far more energy-efficient computing than silicon-based systems, alongside ethical questions about the use of living human tissue in machines.

In Melbourne, Australia, a biological computer built from living human brain cells is being maintained like a living organism — it must be fed, kept warm and cleaned every few days or it dies. The system, called the CL1, is made by an Australian company and is drawing attention as a striking example of biocomputing, where lab-grown neurons perform computational tasks.

Astrophysics researchers suggest Earth's magnetic field is heading for a reversal, which could increase ionizing charged particles reaching the equator by up to 25%. Such particles can damage human cells and may interfere with atmospheric processes. The claim is circulating widely online, with readers debating how severe the health and climate consequences of a weakened magnetic field during a pole flip could actually be.
