Why eukaryotes, not bacteria, evolved complex multicellularity

Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first eukaryotic cells appeared around ...

How cells measure themselves

Ever since scientists discovered cells under the microscope more than 350 years ago, they have noted that each type of cell has a characteristic size. From tiny bacteria to inches-long neurons, size matters for how cells ...

Mystery of Tasmanian devil tumour deepens - for now

(Phys.org) -- The degree of genetic difference to a tumor is not a factor in Tasmanian devils contracting the facial tumor disease, according to research led by the University of Sydney.

Scientists discover giant insect genome

The largest genome of any insect, seven times the size of the human genome, was recently discovered in a grasshopper. In a study published in PLOS ONE, researchers from the German Leibniz Institute for the Analysis of Biodiversity ...

Graphene nanoflakes: A new tool for precision medicine

Chemists funded by the SNSF have created a new compound for flexible drug delivery that specifically targets prostate cancer cells. Incorporating four different molecules, the compound prevents tumor cells from multiplying, ...

Researchers unravel mechanisms that control cell size

Working with bacteria, a multidisciplinary team at the University of California San Diego has provided new insight into a longstanding question in science: What are the underlying mechanisms that control the size of cells?

Nanorods overcome tigecycline resistance of Klebsiella pneumonia

Long-term and excessive use of antibiotics has caused the spread of antibiotic resistance. The time- and cost-consuming process of new antibiotic development results in the much slower emergence of new antibacterial drugs ...
