How are bacterial pathogens able to effectively overcome plants' defense mechanisms? Researchers working with Professor Şuayb Üstün at Ruhr University Bochum, Germany, have found a surprising answer to this question: The pathogens seize tiny compartments in plant cells, known
The cost of toxic leadership in the workplace, and how to avoid it
You will probably recognize toxic leaders when you encounter them. They are the ones whose presence shifts the atmosphere, whose emails create unease, or whose behavior limits the thinking of others. They often interrupt, frequently overlook contributions and hamper other
Synchrotron safety monitoring sheds light on dark photons
A scientist from Tokyo Metropolitan University has proposed using safety monitoring at synchrotron facilities to study the properties of dark photons, hypothetical particles proposed to explain dark matter. Calculations show that the X-ray source at these sites and a
Potential signs of life on distant planets sound exciting, but confirmation can take years
Astronomers can use telescopes to find specific molecules in the atmospheres of neighboring planets, in nebulae—clouds of interstellar dust and gas—hundreds or thousands of light-years away, or in galaxies beyond the far reaches of the Milky Way.

During infection, pathogens must adapt quickly to the conditions to thrive inside the body. A research team at the University of Basel, Switzerland, has uncovered how a key protein switches on the machinery that enables Leptospira pathogens to survive and cause disease. The
Mopane worm and termite sales relieve poverty in rural South Africa—studies explore the impact
South Africa's Limpopo province borders Zimbabwe, Botswana and Mozambique. It is one of the poorest provinces in the country. This is due to a combination of historical underdevelopment, a high unemployment rate, heavy reliance on government grants and a rural-based economy
Two suns are better than one—planets thrive around binary stars
Planets may actually form more easily around double stars than around single stars like our sun, according to new research from astrophysicists at the University of Lancashire. Binary stars are common in our galaxy, yet for a long time astronomers believed that the

You may think of the high-fat, low-carb eating plan as a faddish way to lose weight. But the keto diet is now being used to tackle conditions from severe depression to bipolar disorder and anorexia, with transformative results
Mining the solar system to build a new world
I watched Armageddon again fairly recently with Bruce Willis, oil drillers in space and an asteroid the size of Texas bearing down on Earth. Buried beneath the Hollywood chaos is a genuinely interesting question: What exactly could we do with an asteroid if we got our hands on
CRISPR untangles five-gene protein that helps plants grow in early stages
For most of their lives, plants get their energy from photosynthesis. But during the seed to seedling stage, when they can't absorb light just yet, they rely on other sources, like fatty acids. To process the fatty acids, plant cells, like human cells, rely on a membrane-bound
Japan startup seeks approval of cat kidney disease treatment
A Japanese startup has filed for approval of a new drug to treat chronic kidney disease in cats, the founder said on Monday, offering hope for a common affliction that currently has no definitive cure.
Rare ribosome tweak in E. coli reveals possible antibiotic target
Storing genetic material as DNA or RNA is all well and good for life on Earth, but it would be entirely pointless if we couldn't do anything with it. To use our genetic blueprints, all organisms need to translate the message from their nucleic acid forms into protein, which

A new study by a University at Buffalo social work researcher shows that 43% of frontline workers in the homeless services sector nationally reported an intention to leave their jobs. The findings published in the International Journal on Homelessness represent the first
An acoustic device helps reduce bycatch of endangered Black Sea porpoises
The endangered Black Sea harbor porpoise (Phocoena phocoena relicta) is facing a critical fight for survival. As Europe's smallest marine mammal, this isolated population is being pushed toward extinction by bycatch—the unintentional entanglement in fishing gear. The crisis is
Bacterial defense system builds DNA in unexpected new way to stop viruses
Scientists at Stanford University have discovered that DRT3, a unique defense system found in bacteria, creates DNA to protect against viral infections. DRT3 is made up of two different enzymes called reverse transcriptases, Drt3a and Drt3b, and a piece of noncoding RNA

Improving animal welfare in the lab: AI helps better detect pain
At first glance, the white plastic box with a bright orange floor looks like something for storing children's toys. However, the box isn't used to store Lego bricks; it contains real mice—with the aim of minimizing their suffering. "This box allows laboratory animals to be
What happened after the fast-food pay raise in California? New data explains
Fast-food workers in California may be earning more money, but their employers are cutting their hours to make up for the cost of higher pay. That's from a new study published in Applied Economic Letters in early March. Northeastern University postdoctoral research fellow
Scientists just captured a mysterious quantum “dance” inside superconductors
In a breakthrough experiment, scientists directly imaged how particles pair up in a system that mimics superconductors. Instead of behaving independently, the pairs moved in a synchronized, dance-like pattern—something never predicted before. This suggests a major gap in the
Scientists may have found the brain’s switch for chronic pain
Deep within the brain, scientists have uncovered a hidden “switch” that may decide whether pain fades away—or lingers for months or even years. Researchers found that a small, little-known region called the caudal granular insular cortex (CGIC) acts like a command center,
