How did the complex organisms on Earth arise? This is one of the big open questions in biology. A collaboration between the working groups of Christa Schleper at the University of Vienna and Martin Pilhofer at ETH Zurich has come a step closer to the answer. The researchers succeeded in cultivating a special archaeon and characterizing it more precisely using microscopic methods.
Researchers from Children’s Hospital of Philadelphia (CHOP) and New Jersey Institute of Technology (NJIT) developed new software that integrates a variety of information from a single cell, allowing researchers to see how one change in a cell can lead to several others and providing important clues for pinpointing the exact causes of genetic-based diseases.
Scientists have discovered that the atmosphere contained far less CO2 than previously thought when forests emerged on our planet, the new study has important implications for understanding how land plants affect the climate.

NIBIB-funded researchers are developing a new method to treat pancreatic cancer. In their study, they combined an injectable radioactive gel with systemic chemotherapy in multiple mouse models of the disease. The treatment resulted in tumor regression in all evaluated models, an unprecedented result for this genetically diverse and aggressive type of cancer.
In a study publishing December 20 in Nature Cancer, UCSF researchers found that phenotype switching, as opposed to genetic evolution, may be the escape mechanism that explains the failure of precision therapies to date. They found that some cells shift to a mesenchymal, radiation-resistant phenotype (state) as a stress response following standard therapy.

The use of synthetic food dyes such as Allura Red has increased significantly over the last several decades, but there has been little earlier study of these dyes’ effects on gut health. Khan and his team published their findings in Nature Communications. “What we have found is striking and alarming, as this common synthetic food dye is a possible dietary trigger for IBDs. This research is a significant advance in alerting the public on the potential harms of food dyes that we consume daily,” he said.
In new research published in Nature Communications, University of Sussex scientists demonstrate how a highly conductive paint coating that they have developed mimics the network spread of a virus through a process called 'explosive percolation' – a mathematical process which can also be applied to population growth, financial systems and computer networks, but which has not been seen before in materials systems.
The proton is the only composite building block of matter that is stable in nature, making its properties key to understanding the formation of matter. A team of physicists measured the proton’s electric polarizability, which characterizes the proton’s susceptibility to deformation, or its “stretchability,” in the presence of a photon’s electromagnetic field. The results reveal a puzzling new structure – a bump in the polarizability that nuclear theory cannot explain.
Craving is known to be a key factor in substance use disorders and can increase the likelihood of future drug use or relapse.
Astronomers say they have solved an outstanding problem that challenged our understanding of how the Universe evolved - the spatial distribution of faint satellite galaxies orbiting the Milky Way.
When it comes to predicting disasters brought on by extreme events (think earthquakes, pandemics or “rogue waves” that could destroy coastal structures), computational modeling faces an almost insurmountable challenge: Statistically speaking, these events are so rare that there’s just not enough data on them to use predictive models to accurately forecast when they’ll happen next.
Researchers from Paul Scherrer Institute PSI and ETH Zurich have discovered how proteins in the cell can form tiny liquid droplets that act as a smart molecular glue.
A new tool to identify small molecules offers benefits for diagnostics, drug discovery, and fundamental research.
The Donnan electric potential arises from an imbalance of charges at the interface of a charged membrane and a liquid, and for more than a century it has stubbornly eluded direct measurement. Many researchers have even written off such a measurement as impossible. But that era, at last, has ended. With a tool that’s conventionally used to probe the chemical composition of materials, scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) recently led the first direct measurement of the Donnan potential.
An ICTA-UAB project establishes the direct relationship between green spaces and green gentrification processes in 28 cities in North America and Europe.
Astronomers have found a way to peer into the physics of some of the brightest stars in the sky. Using data from NASA’s Kepler space telescope, an international team of researchers has found new evidence that red giants, dying stars that have exhausted their supply of hydrogen and are in the final stages of stellar evolution, often experience large-scale structural variations, or what are known as “glitches” deep inside their inner core.
Rutgers researchers hope their genome-assembly tool will spur the development of new treatments for bacterial infections.
The London Underground is polluted with ultrafine metallic particles small enough to end up in the human bloodstream, according to University of Cambridge researchers.
Astronauts could be given an enhanced diet during spaceflights that includes a greater variety and quantity of fruits, vegetables, and fish to improve their health and performance compared to standard spaceflight food, reports a study published in Scientific Reports.
With modern therapies for heart failure (HF) with reduced ejection fraction (HFrEF), some patients can improve their cardiac function during treatment.

Astronomers have uncovered a pair of planets that are true "water worlds," unlike any planet found in our solar system. Slightly larger than Earth, they have global oceans at least 500 times deeper than the average depth of Earth's oceans.
Astronomers has found evidence that two exoplanets orbiting a red dwarf star are “water worlds,” planets where water makes up a large fraction of the volume.
UC San Diego Herbert Wertheim School of Public Health and Human Longevity Science led 70 participants from 14 nations in a discussion on the ways in which a gene drive project registry could both contribute to and detract from the fair development, testing and use of gene-drive modified organisms.
Alzheimer’s disease (AD) is the fifth leading cause of death in adults over 65 years old. While many potential treatments for the neurodegenerative disease focus on developing drugs to target key culprits, a relatively new approach aims to more directly treat the brain.
Significantly higher arsenic and uranium concentrations in public drinking water have been linked to communities with higher proportions of Hispanic/Latino, American Indian/Alaskan Native, and non-Hispanic Black residents, according to a new study at Columbia University Mailman School of Public Health.
Bifacial thin film solar cells based on copper indium gallium diselenide or CIGS can collect solar energy from both their front and their rear side – and thus potentially yield more solar electricity than their conventional counterparts. So far, however, their fabrication has led to only modest energy conversion efficiencies.
When the rover Perseverance landed on Mars, it was equipped with the first working microphone on the planet’s surface. Scientists have used it to make the first-ever audio recording of an extraterrestrial whirlwind.

A team of researchers from Southwest Research Institute (SwRI), NASA and the Max Planck Institute for Solar System Research (MPS) have discovered web-like plasma structures in the Sun’s middle corona.
There is a critical need for non-invasive solutions to monitor heart failure progression around the clock. This novel wearable device is based on sensors embedded in a lightweight belt that monitors thoracic impedance, electrocardiogram (ECG), heart rate and motion activity detection. The device was tested in different conditions including sitting, standing, lying down and walking. Findings showed that all of sensors kept track of the changes for all of the different conditions.
