Free Will, I don’t think so

Most thoughts and desires are products of unconscious processes and conditioning rather than deliberate choice.
Our likes, dislikes, and desires are conditioned responses based on past experiences and neural patterns.
Biases, preferences, and decisions often emerge from unconscious factors rather than conscious deliberation.
True free will lies in the capacity of consciousness to observe spontaneous thoughts without compulsion or identification.

SpiderBot experiments hint at “echolocation” to locate prey

Researchers at Johns Hopkins University's Terradynamics Laboratory are using spider robots to study the behaviors of real spiders in locating prey.
Spiders exhibit crouching behavior to sense differences in web frequencies and locate prey that is not moving.
The research offers evidence for the hypothesis that spiders use a form of echolocation to find immobile prey.
The experiments with robot models provide reproducible results and offer insights into the biological system of spiders.

Derecho-Induced Skyscraper Damage

Derechos, short-lived, intense wind storms, have been found to cause more damage to skyscrapers in Houston compared to hurricanes with similar wind speeds.
Researchers have discovered that broken windows in skyscrapers were concentrated in areas facing other tall buildings during a derecho.
Wind tunnel experiments revealed that downbursts, strong downward wind bursts, between nearby buildings caused extremely strong suction forces along a skyscraper's face, even stronger than those experienced in higher hurricane-force winds.
As a result, designers may need to consider the effects of downburst wind patterns on skyscrapers in regions prone to derechos.

‘Milestone’ as Square Kilometre Array Observatory releases its first low-frequency image of the cosmos

The Square Kilometre Array (SKA) Observatory has released the first images from its partially built low-frequency telescope in Australia, known as SKA-Low.
The image contains 85 of the brightest known galaxies in that region, observed at 150MHz to 175 MHz, with each galaxy having a black hole at its center.
The SKA-Low telescope will have 131,072 two-metre-high antennas that will act as a single instrument, enabling observations of over 600,000 galaxies.
The SKA-Low and SKA-Mid telescopes, with a combined cost of £1bn, are expected to begin making science observations in 2028 and will help answer cosmology's most enigmatic questions.

Manu jumping: the physics of making a bigger splash

Manu jumping is a competitive sport that involves creating the highest splash when jumping into the water.
According to a study, the best manu jumpers enter the water back first, creating a V-shape with their legs and upper body.
A 45° angle between the legs and torso results in the highest splashes, as it creates a deep and wide air cavity that quickly closes.
The study also found that rolling and kicking in the water, along with an optimal opening time of 0.26 s, contributes to making the highest splashes.
