Lipid signals help cells seal the damage from bacterial attacks, researchers discover
Epithelial cells form the body's frontline barriers, helping keep microbes, toxins and other harmful substances out. Yet these protective cells are constantly exposed to threats, including microbial infections. Some bacteria produce pore-forming toxins that can oligomerize and
Resource scarcity influences maternal brain activity and caregiving in rats
When mothers do not have the necessary resources to raise their children, this adversity causes substantial stress that can hinder caregiving and lead to postpartum depression. In a new study in JNeurosci, Millie Rincón-Cortés and colleagues from the University of Texas at

Space radiation sparks: A biological cascade of cancer
Deep space travel comes with a huge potential downside—radiation exposure that can kill an astronaut either quickly or slowly over time if not managed correctly. But what exactly does that mean, and is there any way to handle it other than sticking more and more protective
Tiny ancient black holes may live in a five-dimensional world
Primordial black holes (PBHs) don't exist as far as we know. But if they did, these hypothetical objects would have formed in the early universe rather than from dying stars, and they may even make up dark matter. That's not the end of the weirdness. Their formation could have
Farmer-macaque conflict in Algeria poses a complicated conservation challenge
One of the hardest challenges in wildlife conservation arises when the habitat of a species in need of protection overlaps with land used by humans. Wolves and bears can kill livestock, elephants can damage homes and other property and wild boar can damage crops.
X-rays and AI reveal how spacecraft heat shields burn in real time
Heat shields are one of the most important parts of any spacecraft that intends to enter an atmosphere. And the material they are made of is critical. Improving them has been a challenge, though, as researchers typically only get "before" and "after" pictures of a heat shield's
Bumblebees carry bacteria-killing viruses to cherry blossoms, reducing bacterial populations in experiments
As they fly about their usual business of pollinating flowers, bumblebees could help protect fruit trees from disease by carrying a natural treatment directly to where it is needed.
'Flying rivers' above South America form drainage networks resembling those on land
Water does not flow only through rivers on the ground. Vast quantities of water also move through the atmosphere, carried by winds from oceans and land before eventually falling as precipitation hundreds or even thousands of kilometers away. These persistent pathways of

Most people find some sounds unpleasant, such as a baby crying or a siren, because of features such as their pitch, frequency or loudness. However, for some people, very ordinary sounds, such as chewing, sniffing, breathing, swallowing, finger tapping or clicking a pen, can
The 'dream job' myth: Why a fulfilling career does not have to define your life
At some point, most of us have heard the same advice about work: find a job you love, and you'll never work a day in your life. The idea of a "dream job" sounds inspiring, even noble; it suggests that work can be a source of meaning, identity and personal fulfillment. But this
