Birds change altitude to survive epic journeys across deserts and seas

Every year, billions of birds undertake extraordinary migrations, crossing vast deserts and open seas with no place to stop, feed, or rest. A new study reveals that small migratory birds adjust how high they fly over these ecological barriers, and that their strategies depend on wing morphology and plumage color.

Cleaner fish show intelligence typical of mammals

When presented with a mirror, the tiny fish not only recognized themselves, but experimented with the mirror themselves, interacting with it using a scrap of food.

Robot clean-up crews tackle litter on Europe’s seabed

A ship with a crane floats in the Mediterranean sun at a marina in Marseille, France. The crane whirs as it hauls waste from the seabed and, when the wire breaks the surface, the gripper at the end is clutching a rubber tire covered in algae. As the day advances, rusted metal ship parts, fences and even heavy machinery emerge from under the waves and are dragged onto another vessel.

Scientists reveal best- and worst-case scenarios for a warming Antarctica

Though Antarctica is far away, changes there will impact the rest of the world through changes in sea level, oceanic and atmospheric connections and circulation changes. Changes in the Antarctic do not stay in the Antarctic.

Baby chicks match sounds to shapes just like humans

When we hear certain sounds, our brains often pair them with specific shapes. For example, most people will associate a sharp-sounding word with a jagged, pointed shape, while a soft, rolling word is linked to something smooth and curved.

Quantum entanglement could link distant telescopes for sharper images

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, entails comparing the light signals originating from distant objects and picked up by different telescopes that are at different locations, then reconstructing images using computational techniques.

US particle accelerators turn nuclear waste into electricity, cut radioactive life by 99.7%

This system uses a particle accelerator to fire high-energy protons at a target (such as liquid mercury), triggering a process called “spallation.” This releases a flood of neutrons that interact with unwanted, long-lived isotopes in nuclear waste.

Why do some melodies feel instantly right, balanced, memorable and satisfying, even if you have never heard them before? New research from the University of Waterloo suggests that more than creativity is at play.

Blood test ‘clocks’ can predict when Alzheimer’s symptoms will start

Amyloid and tau levels are similar to tree rings—if we know how many rings a tree has, we know how many years old it is. It turns out that amyloid and tau also accumulate in a consistent pattern and the age they become positive strongly predicts when someone is going to develop Alzheimer’s symptoms.

Immune cells from pediatricians help uncover an antibody cocktail against RSV and hMPV

The respiratory syncytial virus (RSV) causes mild cold-like symptoms in healthy adults, but is the leading cause of lower respiratory tract infections in children, accounting for 30–50% of hospitalizations. The human metapneumovirus (hMPV) is the second most common cause of lower respiratory tract infections in children, accounting for 6–15% of hospitalizations. Both are also major causes of severe respiratory infections in older adults and immunocompromised people.

How the humble silkworm could help us discover new anti-aging treatments

When scientists want to study aging and how to slow it down, they often turn to microscopic worms or lab mice among other models. The former are too different from humans, while the latter are expensive and take too long to study. But there’s a new model in town that can potentially help us wind the clock back, and that is the silkworm (Bombyx mori).

The cooling system that lets bees beat the heat when hovering

To stay in the air when hovering over a flower, bumble bees continually flap their wings rapidly, a metabolic process that generates a massive amount of internal heat. Their flight muscles work so intensely that they can raise the insect’s body temperature by 30°C to 35°C above the surrounding air. On a scorching summer day, this can put them at risk of overheating, which may be fatal.

Orbital AI data centers could work, but they might ruin Earth in the process

Musk’s reputation might suggest otherwise, but according to experts, such a plan isn’t a complete fantasy. However, if executed at the scale suggested, some of them believe it would have devastating effects on the environment and the sustainability of low Earth Earth orbit.

Why AI may overcomplicate answers

When making decisions and judgments, humans can fall into common “traps,” known as cognitive biases. A cognitive bias is essentially the tendency to process information in a specific way or follow a systematic pattern. One widely documented cognitive bias is the so-called addition bias, the tendency of people to prefer solving problems by adding elements as opposed to removing them, even if subtraction would be simpler and more efficient.
