CERN created a "mini Big Bang" with the lightest atoms ever made.

ZAP Notícias4 September 2026 at 07:00

CERN created a "mini Big Bang" with the lightest atoms ever. Scientists collided light nuclei of oxygen and neon, successfully replicating signals from primordial matter that existed in the first moments of the Universe. The main discovery is that much smaller collisions than previously thought are needed to create this extreme state.

In the first moments of the Universe, about 13.8 billion years ago, matter did not exist as we know it today. About a millionth of a second after the Big Bang, the Universe was a hot and dense soup that scientists call quark-gluon plasma, or QGP.

This research shows that the large colliders that were thought necessary are not required to reproduce the conditions of the early Universe. Smaller particle accelerators may now be sufficient to study this primordial state of matter.

Work anxiety symptom can be mistaken for laziness

A HuffPost article, replayed this Thursday, reveals that work procrastination — frequently interpreted as negligence — is often an anxiety symptom. Psychologists and psychotherapists explain that, when professional pressure exceeds the individual's response capacity, the nervous system enters alert mode and reacts with "freezing," perceiving the task list as a threat. This defense mechanism, although providing momentary relief, feeds a vicious cycle of avoidance and growing anguish. In Portugal, where professional burnout indicators are particularly high in the European Union, specialists warn against excessive self-criticism and recommend five practical strategies: rigorous weekly planning, scheduled breaks, starting with simple tasks, priority resolution of the main obstacle, and softening guilt.

Researchers successfully test genetic editing strategy for Machado-Joseph disease

Researchers from the Centre for Neuroscience and Cell Biology at the University of Coimbra (CNC-UC) and GeneT – Centre of Excellence in Gene Therapy successfully tested a genetic editing strategy for Machado-Joseph disease, a neurodegenerative disease that affects the brain and motor abilities. The study reveals new data that may contribute to the development of therapeutic approaches for this pathology, opening promising prospects for future treatments.

CSIC creates magnetic "nanoflowers" that capture and transform nanoplastics from water

Researchers from the Instituto de Ciencia de Materiales de Madrid at CSIC have developed magnetic iron oxide "nanoflowers" that can capture PET nanoplastics from water and transform them into reusable materials capable of removing other pollutants, such as dyes and heavy metals. These structures, with a flower-like shape and nanoscale size, use magnetic force for efficient separation and can be recycled up to five times without losing effectiveness, representing a significant advancement for contaminated water treatment and for a circular economy in plastic waste management.

How is excess mortality due to heat calculated in Portugal?

The article explains how excess mortality due to heat is calculated in Portugal, highlighting the ÍCARO surveillance system, coordinated by the National Health Institute. Instead of counting deaths officially attributed to heat, the system measures how many deaths occur above the expected number for each period, using statistical and epidemiological methods to separate the impact of high temperatures from the usual mortality variation. When temperatures exceed 40°C, epidemiologists can detect the "statistical signature" left by heat, even when it does not appear as a direct cause on death certificates.
