Phys.org / 'Reborn' black hole awakens after 100 million years of silence
One of the most vivid portraits of "reborn" black hole activity—likened to the eruption of a "cosmic volcano" spreading almost 1 million light-years across space—has been captured in a gigantic radio galaxy.
Phys.org / How cells stay healthy: New insights into a selective protein cleanup system
To stay healthy, our cells rely on a self-cleaning mechanism that removes defective or unnecessary components. This process, known as autophagy, has been linked not only to cellular maintenance but also to various diseases ...
Phys.org / How cholera virulence is activated: A long-sought structural explanation
Cholera remains a major global public health challenge, with an estimated 1.3 to 4 million cases and tens of thousands of deaths reported worldwide each year. Caused by the bacterium Vibrio cholerae, the disease spreads primarily ...
Phys.org / Frequency comb lasers enable clearer observation of black holes
Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies. To observe distant black holes clearly, multiple radio telescopes must capture cosmic signals ...
Phys.org / Exposing how humidity can escalate a heat wave
When Floridians talk about extreme weather, hurricanes dominate the conversation. Each season brings updates on storm tracks, cone predictions and wind speeds, all in the hopes of predicting the unpredictable. But a quieter, ...
Phys.org / Same moves, different terrain: How bacteria navigate complex environments without changing their playbook
Just like every other creature, bacteria have evolved creative ways of getting around. Sometimes this is easy, like swimming in open water, but navigating more confined spaces poses different challenges.
Tech Xplore / Novel thick electrode enhances battery power and capacity for a 75% increase in output
A research team affiliated with UNIST has unveiled a new type of thick electrode aimed at solving a common challenge in battery design: As the capacity increases, power often decreases. This breakthrough could enable electric ...
Phys.org / Mummified cheetahs found in Saudi caves shed light on lost populations
Scientists have uncovered the mummified remains of cheetahs from caves in northern Saudi Arabia.
Phys.org / Overcoming symmetry limits in photovoltaics through surface engineering
A recent study carried out by researchers from EHU, the Materials Physics Center, nanoGUNE, and DIPC introduces a novel approach to solar energy conversion and spintronics. The work tackles a long-standing limitation in the ...
Medical Xpress / Standard TB and HIV treatments leave lung immune system impaired, study shows
The immune system remains seriously out-of-whack—in an inflammatory state of overactivation and impaired functionality—following the international gold standard for treating people with latent tuberculosis (TB) and HIV, ...
Phys.org / What to know about venomous snakes in North Texas after recent diamondback discovery
Texas is home to more than 100 snake species, including the western diamondback rattlesnake, which was recently documented for the first time in Denton County after being found in a suburban garage.
Phys.org / Seagrass meadows could be good for your health—yet they're disappearing fast
The well-being benefits of nature are often linked to forests or habitats that support diverse pollinators. Spending time in green spaces reduces stress and anxiety, for example.
