Tightening the focus of subcellular snapshots: Combined approach yields better cell slices for cryoET imaging

Tightening the focus of subcellular snapshots: Combined approach yields better cell slices for cryoET imaging

Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), shoots electrons through a frozen sample. The images formed by the electrons that emerge allow researchers to reconstruct the internal architecture of a cell in 3D with near-atomic resolution.

Living together with differences: Mathematical model shows how to reduce social friction without forcing consensus

Living together with differences: Mathematical model shows how to reduce social friction without forcing consensus

Opinion polarization is often considered as the primary driver of social friction, leading to exhaustive efforts to force a consensus. However, new research suggests a more pragmatic goal: reducing the friction of disagreement without necessarily eliminating the diversity of opinion.

How a respiratory bacterium obtains essential lipids from the human body and targets fat-rich tissues

How a respiratory bacterium obtains essential lipids from the human body and targets fat-rich tissues

A multidisciplinary team has uncovered a key mechanism that allows the human bacterium Mycoplasma pneumoniae—responsible for atypical pneumonia and other respiratory infections—to obtain cholesterol and other essential lipids directly from the human body.

How to prevent charge buildup in a lunar rover

How to prevent charge buildup in a lunar rover

As they roll across shadowed regions of the moon's surface, future lunar rovers could develop hazardous buildups of electric charge on their wheels. Through new analysis published in Advances in Space Research, Bill Farrell at the Space Science Institute in Colorado, together with Mike Zimmerman at Johns Hopkins University, outline realistic precautions for mitigating this risk—offering valuable guidance for engineers designing future lunar missions.

Scientists design artificial pain receptor that senses pain intensity and self-heals

Scientists design artificial pain receptor that senses pain intensity and self-heals

All over the body are tiny sensors called nociceptors whose job is to spot potentially harmful stimuli and send warning signals to the brain and spinal cord, helping protect us from injury or tissue damage.

Experiments bring Enceladus' subsurface ocean into the lab

Experiments bring Enceladus' subsurface ocean into the lab

Through new experiments, researchers in Japan and Germany have recreated the chemical conditions found in the subsurface ocean of Saturn's moon, Enceladus. Published in Icarus, the results show that these conditions can readily produce many of the organic compounds observed by the Cassini mission, strengthening evidence that the distant world could harbor the molecular building blocks of life.
