New chemical method advances toward targeted RNA medicine

Targeted drugs aim to pinpoint the exact location in the body where diseased tissue is located and where the medicine is required. The manifold benefits of administering a targeted drug include heightened efficacy, as the ...

Researchers achieve unprecedented control of polymer grids

Synthetic polymers are ubiquitous—nylon, polyester, Teflon and epoxy, to name just a few—and these polymers are all long, linear structures that tangle into imprecise structures. Chemists have long dreamed of making polymers ...

Quantum dots form ordered material

Quantum dots are clusters of some 1,000 atoms which act as one large "super-atom." It is possible to accurately design the electronic properties of these dots just by changing their size. However, to create functional devices, ...

The birth of a male sex chromosome in Atlantic herring

The evolution of sex chromosomes is of crucial importance in biology as it stabilizes the mechanism underlying sex determination and usually results in an equal sex ratio. An international team of scientists, led by researchers ...

Directed protein evolution with CRISPR-Cas9

"Directed evolution" is the process by which scientists produce tailor-made proteins for cell biology, physiology and biomedicine in the laboratory. Based on this method, Max Planck researchers from Martinsried have now developed ...

Scientists model a crucial component of cell division

During the process of cell division, chromosomes must be distributed equally between the two emerging daughter cells. One copy of each chromosome is created and remains glued to the original until threads, called microtubules, ...

Engineering plants for a sustainable future

In the search for sustainable materials, the day-to-day structures of plants could help replace polluting materials and plastics with ones that are less detrimental to our environment.
