Why are giant pandas born so tiny? Born pink, blind, and helpless, giant pandas typically weigh about 100 grams at birth—the equivalent of a stick of butter. Their mothers are 900 times more massive than that.

Nanoscience breakthrough: Probing particles smaller than a billionth of a meter Scientists at Tokyo Institute of Technology (Tokyo Tech) have developed a new methodology that allows researchers to assess the chemical composition and structure of metallic particles with a diameter of only 0.5 to 2 nm. This breakthrough in analytical techniques will enable the development and application of minuscule materials in the fields of electronics, biomedicine, chemistry, and more.

Newfound Martian aurora actually the most common; sheds light on Mars' changing climate A type of Martian aurora first identified by NASA's MAVEN spacecraft in 2016 is actually the most common form of aurora occurring on the Red Planet, according to new results from the mission. The aurora is known as a proton aurora and can help scientists track water loss from Mars' atmosphere.

Protein injections in medicine Pathogens can use a range of toxins to damage their host organism. Bacteria, such as those responsible for causing the deadly Plague, use a special injection mechanism to deliver their poisonous contents into the host cell. Stefan Raunser, Director at the Max Planck Institute for Molecular Physiology in Dortmund, together with his team, has already produced a detailed analysis of this toxin's sophisticated mechanism. They have now succeeded in replacing the toxin in this nano-syringe with a different substance. This accomplishment creates a basis for their ultimate goal to use bacterial syringes as drug transporters in medicine.
