Super El Niño officially arrives: heat waves, flooding and thousands of dead seabirds

Scientists have officially confirmed the arrival of the Super El Niño phenomenon, which has already triggered a sharp rise in ocean temperatures, deadly flooding and the death of thousands of seabirds. The climate anomaly is causing extreme weather conditions across multiple continents. This is one of the strongest occurrences of the phenomenon in the history of measurements.

Are governments doing enough to prepare for the effects of El Niño?

New nature reserve in Beskid Żywiecki: 50 hectares of forest on Wielka Rycerzowa massif

The Regional Directorate for Environmental Protection in Katowice has issued a decision to establish a new nature reserve in Beskid Żywiecki. Protection will cover 50 hectares of ecologically valuable forests on the Wielka Rycerzowa massif. The peak is popular with tourists, who will need to comply with new rules for access and movement in the area.

Should creating new nature reserves take priority over tourist access?

New York scientists discover how protein shields healthy cells

Researchers at Memorial Sloan Kettering Cancer Center in New York have solved a mystery from over 30 years ago: a substance that triggers inflammation also serves a protective function, safeguarding healthy cells from damage. Results were published in Nature. The discovery could accelerate development of new therapies for inflammatory bowel disease, asthma, and certain cancers in the future.

Could this discovery realistically change treatment of inflammatory diseases within a decade?

Protein found to accelerate aging without triggering inflammation

Scientists discovered that the protein granzyme K accelerates organ aging processes. Mice lacking this protein had better-functioning hearts and livers and less kidney damage. The discovery may open the way to therapies that slow aging without the risk of triggering inflammation.

Should therapies slowing organ aging be a priority for medical research funding?

Lumina simulation traced 2 billion years of universe history from first stars

An international team of scientists created the Lumina simulation, which tracks nearly 2 billion years of universe history — from the emergence of the first stars about 45 million years after the Big Bang. The model covers a region with sides of ~1.6 billion light-years, roughly one hundred times larger in volume than earlier simulations. Calculations were performed on the Frontier supercomputer at Oak Ridge National Laboratory, with results published in "Monthly Notices of the Royal Astronomical Society". The simulation showed how radiation from stars ionized hydrogen around galaxies and r...

First CRISPR therapy editing genes inside the body nears FDA approval

A groundbreaking gene therapy using CRISPR technology could become the first to gain approval from the U.S. Food and Drug Administration for modifying genes directly inside a patient's body. Previous methods required extracting cells from the patient, editing them outside the body, and reinfusing them—a costly and complex process. The new approach eliminates this step, potentially simplifying treatment and reducing costs significantly.

Should the FDA approve CRISPR therapy that modifies genes inside the body?

Scientists create most detailed atlas of brain's basal ganglia

An international research team profiled nearly 26 million brain cells from the basal ganglia, creating a cross-species reference database — the most comprehensive in history. The atlas is intended to help understand mechanisms of diseases such as Parkinson's disease, addiction and other neurological disorders. Results were published in Nature.

Climate Action Tracker report: world will warm 2.7°C without changes

Climate Action Tracker published a report at COP31, showing that at current emission reduction rates global temperature will rise 2.7°C by the end of this century. Scientists warn that this scenario could mean losing the ability to adapt to new climate conditions.

What causes senior body odor? Chemical compound 2-nonenal

The distinctive body odor of older people results not from poor hygiene but from biochemical processes in the skin. Japanese chemist Dr. Shinichiro Haze demonstrated in a study with 22 volunteers that the compound 2-nonenal appears only in people over 40 and its concentration increases with age. It forms from oxidation of unsaturated fatty acids in sebum through oxygen and UV radiation. The intensity of the odor can be reduced through an antioxidant-rich diet, avoiding nicotine, and using appropriate skincare products.

Will knowledge of 2-nonenal change society's approach to senior body odor?

Microplastics turn waters near Great Pacific Garbage Patch greener and bluer

Waters surrounding the Great Pacific Garbage Patch are becoming greener and bluer due to high concentrations of microplastics floating on the surface. The findings were published in Nature. This provides new evidence of how widespread plastic pollution affects the optical properties of oceans.

NIH study: everyone carries gene variants affecting drug response

An analysis of data from nearly 100,000 Americans in the National Institutes of Health's All of Us program found thousands of new variants in 16 genes that influence how the body responds to drugs — so-called pharmacogenes. Every participant had at least one such variant, and one in four was taking a drug that their genes could affect. The study stands out for its exceptionally diverse group of participants in terms of ethnic background, which allowed researchers to identify previously unknown variants.

Should pharmacogenetic testing be standard before prescribing drugs?

Teghaz 001: Martian meteorite shows traces of ancient liquid water

Scientists confirmed that Teghaz 001—eight fragments totaling about 800 grams, found in 2022 on the Sahara in Mali—is one of the oldest Martian meteorites to reach Earth. NASA-funded research detected traces of liquid water in the rock, opening a new window on early Mars history and potentially habitable conditions. The largest fragment weighs 442 grams and is the size of a fist.

Scientists discover blood signal that may detect ovarian cancer in early stage

Researchers from Hoag Family Cancer Institute in Newport Beach, California described in Nature Medicine an RNA molecule called Tu-Stroma, whose elevated blood level indicates precancerous changes in fallopian tubes (STIC). In the study, the test detected STIC in 92.3% of sick women and correctly identified 98.2% of healthy ones. In women with genetic risk of ovarian cancer, a negative result would be correct in nearly 100% of cases. The discovery may help avoid preventive surgery to remove fallopian tubes and ovaries in patients who do not actually have precancerous changes.

Should a blood test replace preventive surgery in women with genetic risk of ovarian cancer?

Ozone hole over Antarctica reaches largest size in a decade

In 2026, the Antarctic ozone hole grew to the seventh largest value on record, approaching its historical maximum, NASA reported. Unusual weather conditions were the cause. Scientists note that international restrictions on ozone-depleting substances have prevented even greater damage, and the ozone layer continues to recover.

Aneto glacier in Pyrenees will vanish within a decade

Aneto — one of southern Europe's largest glaciers, located on the highest peak of Spain's Pyrenees — is melting at an alarming rate and will disappear within the next decade, according to scientists. Its loss is further evidence of advancing global warming. Glaciologists are studying Aneto as an important research case to better understand glacier melt dynamics.

Fossil fuel emissions set to fall in 2026, but total CO₂ continues rising

Scientists forecast that global CO₂ emissions from fossil fuels will decline for the first time in 2026, driven by renewable energy growth and electromobility. Yet rising emissions from deforestation risk pushing total CO₂ to a new record. Researchers warn the carbon budget for keeping warming within 1.5°C could be exhausted in less than four years.

Early Alzheimer's symptoms may develop outside the brain

Scientists have found that early signs of Alzheimer's disease can develop outside the brain – genetic mutations linked to the hereditary form of the disease disrupt nerve-muscle connections without involving the brain or spinal cord. The study was conducted on miniature laboratory models built from human cells. The discovery may explain why some patients experience balance and walking problems long before memory problems appear.
