AI deep denoiser can remove clouds from satellite images

Thick cloud cover can completely obscure the surface of the Earth from satellite view, while thinner haze and shadows distort the image of rural and urban regions. As such, many remote sensing images for monitoring climate, crops, and urban growth are only partially usable.

Courtship is complicated, even in fruit flies

Love is in the air for the vinegar fly. Drosophila melanogaster has long been a model for understanding how brains translate sensory information into courtship behavior. Male flies perform a multitude of romantic actions—orienting, tapping, chasing and singing—directed toward

A new method reveals hidden rules of gene control

Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene expression. Scientists have now developed a way to silence that cellular noise, revealing transcription drivers by reconstructing transcription outside of the

The optical engineering required to photograph an Earth twin

More and more papers are coming out about the upcoming Habitable Worlds Observatory (HWO). As the telescope moves from theory to practice (and physical manifestation), various working groups are discovering, defining, and designing their way to the world's next major exoplanet

Seabird conservation starts upstream, scientists say

New research from Monash University, in collaboration with Phillip Island Nature Parks, has found conclusive evidence that rivers are vital drivers of food and habitat for seabirds around the world. The research, published in Biological Reviews, examined 51 scientific studies

Less sugar as a baby, fewer heart attacks as an adult

People whose sugar intake was restricted before birth and in early childhood had markedly lower rates of heart disease later in life. Compared to those never exposed to rationing, their risks of heart attack, stroke, heart failure, and cardiovascular death were cut by roughly

How the echolocation of bats has shaped their skulls

Bats are some of the most highly specialized mammals to have ever evolved. This includes not only the evolution of active flight, but also their echolocation. This ability requires the bats to produce high frequency noises and then receive the sound back and interpret it to

AI imaginary friends no substitute for human connection

Loneliness and social isolation are now recognized as major public health threats, prompting governments to explore technological solutions. Research from Monash University argues new AI "digital companions" marketed as a solution for loneliness are profoundly unethical, and

Why laws named after tragedies win public support

When lawmakers name bills after victims of tragedy—such as Megan's Law or the Brady Handgun Violence Prevention Act of 1993—public support surges, but this emotional boost may come at the expense of sound policymaking, according to research published in the journal Psychology,

Shining a light on the secret life of carbon dioxide in cells

Carbon dioxide (CO₂) connects us to the natural world: What we breathe out becomes fuel for forests. But inside our own bodies, CO₂ has a secret life. It sparks chemical reactions, shapes metabolism, and may even act as a signaling molecule—and a new tool is finally letting

Study uncovers how schools circumvent suspension bans

New research emerging from SFUSD's Shoestrings program reveals informal exclusionary discipline is a widespread problem—but there are solutions. When San Francisco Unified School District created the Shoestrings program—an effort to reduce racial gaps in early childhood
