Author: José R. Pineda got his Ph.D. from University of Barcelona in 2006. Since 2007 he has worked for Institut Curie and The French Alternative Energies and Atomic Energy Commission. Currently he is a researcher of the UPV/EHU. He investigates the role of stem cells in physiologic and pathologic conditions. Research in oncology advances very […]

In 1873, the microscopist Ernst Abbe stipulated a physical limit for the maximum resolution of traditional optical microscopy: 0.2 micrometers, or 200 nanometers (the shortest wavelength for visible light, the extreme limit of violet). This meant that scientists could distinguish whole cells, as well as some parts of the cell called organelles. However, they would […]

Climate change disrupting lives of Europe’s bats The changing climate in Europe is affecting bats, disrupting their hibernation and hurting their ability to feed their offspring, which are being born sooner, according to researchers. BBC Studies describe “global road map of development” Using single-cell sequencing, researchers have mapped out the growth of individual cells in […]

Single-celled amoeba uses molecular mechanisms similar to complex life The single-celled amoeba Capsaspora owczarzaki has the same molecular tools as more complex organisms to help it move through various life stages. The findings suggest multi-celled mechanisms may have been in place long before animals evolved. Science News New questions raised about Lyme disease following discovery […]

Graphene, carbon nanotubes help spiders spin stronger webs Several spiders sprayed with mixtures of water and either graphene particles or carbon nanotubes went on to weave markedly stronger webs, according to researchers at the University of Trento in Italy. The scientists found that webs made by spiders sprayed with the nanotubes produced the strongest silk […]

Young galaxy clusters discovered More than 200 young galaxy clusters have been documented by astronomers using data gathered by the Planck and Herschel space telescopes. The researchers have released photos of the clusters, which will be studied further in the hope answers can be found to many cosmic questions like how galaxies grow and the […]

The human brain is arguably the most fascinating organ found in nature. Its complexity has been known since Santiago Ramón y Cajal pioneering work showed the central nervous system (CNS) was a contiguous neuronal network where neuron is the basic unit as opposed to the view of the brain being a single continuous network (reticulum) […]

Bacteria are the workhorses for a large number of biotechnological processes. From different fermentation processes to insulin production, they are widely used in industry due to their efficiency, fast duplication times and ease of maintenance. But often their behaviour it´s much more complex than one would expect from a unicellular organism. This is where the […]

Plant that consumes nickel found in the Philippines A plant that thrives in nickel-rich dirt has been discovered in the Philippines. Rinorea niccolifera can absorb large amounts of nickel through its leaves. UPI Regrown bone in monkeys using pluripotent stem cells It could be possible to grow new bone in humans using induced pluripotent stem […]
