The climate crisis arising from greenhouse gas emissions has led to a greater emphasis on energy security, and affordability, to ensure a smooth energy transition. The decarbonization of the energy sector will promote a reduction in carbon emissions and will minimize catastrophic natural disasters. The deployment of low-carbon technology towards a sustainable and clean energy […]
To eat, a cell needs to carry its main nutrients (sugars, lipids, and peptides –pieces of proteins–) across the cell membrane. To do so, it has a number of molecular transporters. Interestingly, although sugar transporters are highly specific to the type of sugar they transport, peptide transporters are not picky at all. This promiscuity has […]
New archaeology method could confirm Bible event Thermal demagnetization, a new method used on mud bricks that are thousands of years old, may help archaeologists understand information preserved in burned material. The technique could reveal how building materials were made, and the authors of the study say in this case it corroborates the Bible’s description […]
Mitochondria are the primary energy providers for cell activities. The quantification of the size and geometry of mitochondria is crucial to basic neuroscience research, as it contributes to the identification of neuron types. This quantification is also informative to clinical studies where energy-usage unbalances are implied, like bipolar disorder or diabetes. High-resolution imaging technologies like […]
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. Solid cancerous tumor is a […]

Sensors are essential tools for detecting and analysing trace molecules in a variety of fields, including environmental monitoring, food safety, and public health. However, developing sensors with high enough sensitivity to detect these tiny amounts of molecules remains a challenge. One promising approach is surface-enhanced infrared absorption (SEIRA), which uses plasmonic nanostructures to amplify the […]
T-cell acute lymphoblastic leukemia (T-ALL) is a hematological malignancy that affects both children and adults. Although with current chemotherapy regimens cure is achieved in ~80% of pediatric patients, adults fare more poorly with only 40% 5-year overall survival . Restricted cellular subsets with asymmetrically enriched leukemia-initiating cell (LIC) activity have been reported in human and […]
Octopus DNA helps scientists resolve geological mystery Scientists analyzed the genetic history of an octopus species living in the Antarctic to confirm a theory about when the West Antarctic ice sheet last collapsed. The Turquet’s octopus has different populations separated by the West Antarctic ice shelves today, but the creature’s family tree indicates that the […]
There are numerous ongoing observational campaigns that will take on the wealth of information encoded in the clustering of matter in the universe. These observations will map the position and shapes of hundreds of millions of galaxies up to tens of thousands of square degrees. Although it will be crucial to keep statistical uncertainties and […]
