Is an earthquake behind the Shroud of Turin image?

Researchers propose that a 33 A.D. Old Jerusalem earthquake triggered neutron radiation, causing the Shroud's distinctive image and potentially leading to incorrect radiocarbon dating results. The theory is based on piezonuclear fission reactions and suggests that neutron emissions from earthquakes could have imprinted the image onto t...

Study challenges a close link between recent weight gain and diabetes

A recent study published in PLOS Medicine suggests that type 2 diabetes may not be directly linked to substantial weight gain over time. Instead, researchers identified distinct patterns of obesity development, including stable overweight individuals and those who experience continuous weight gain before diagnosis. The findings highlig...

Man's best friend equally adapted to high altitudes of Tibet

A study published in Molecular Biology and Evolution found that Tibetan Mastiffs have undergone genetic adaptations to survive at high altitudes. The research identified 16 genes involved in energy production critical for high-altitude survival, suggesting convergent evolution between dogs and humans.

No clowning around: Juggling sheds light on how we run

A study by Johns Hopkins engineers used juggling to investigate how vision and the sense of touch help control limb movement, shedding light on potential treatments for neurological diseases. Adding haptic feedback improved performance, but didn't correct errors, highlighting the brain's reliance on timing information.

Fish living near the equator will not thrive in the warmer oceans of the future

A recent study found that six common species of fish near the equator are unable to survive in warmer waters, with some species experiencing a narrow temperature range. This suggests that climate change poses a significant threat to these fish populations, which could have devastating consequences for human societies reliant on them.

Measuring wind turbines remotely

Researchers have developed a technological system to measure wind turbine oscillations from a distance of several hundred meters. The system uses a laser that automatically tracks the motion of rotor blades, collecting data on precise positions and building a model of rotary motion.

Massive neutrinos solve a cosmological conundrum

Scientists have combined Planck spacecraft and gravitational lensing observations to accurately measure the mass of ghostly sub-atomic particles called neutrinos for the first time. The team finds that massive neutrinos can explain the discrepancies between cosmological results and observations of large-scale structures in the Universe.

Brain researchers discover how Galileo's visual illusion works in the mind's eye

Brain researchers discovered how Galileo's visual illusion works in the mind's eye, revealing that it occurs due to non-linear and exaggerated responses to light stimuli. This effect is responsible for various phenomena, such as why certain objects appear larger or smaller based on their dark parts in bright daylight.
