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 […]

In their recent paper “Telling Gender: The Pragmatics and Ethics of Gender Ascriptions” , the philosophers Quill Kukla and Mark Lance (well known in the philosophy of language as authors of the 2009 essential book Yo! And Lo! The Pragmatic Topography of the Space of Reasons ) embark on a journey into the heart of […]

When plants are infected by pathogens, suffer from a lack of water or have to react to other external stimuli, the first thing they do is increase the proton and calcium concentration in the affected cells. The protons and calcium ions then act like messenger substances that trigger further reactions in the cell. The interactions […]

One of the intriguing and central mysteries in contemporary neuroscience revolves around the intricate relationship between the brain and the mind. While our understanding of neurons, neurotransmitters, and neuronal receptors has advanced significantly, the elusive question remains: How do these complex chemical and electrical processes translate into thoughts, emotions, and behaviors? Gaining insight into these […]

Morning people may have inherited Neanderthal genes People’s predisposition to wake up early may be linked to inherited genetic variants from Neanderthals, who lived at high latitudes in Europe and Asia and evolved to cope with seasonal variation in daylight. Full Story: CNN Lights attract migrating birds into cities at night Light pollution draws migratory […]

A cement is any of various substances used for bonding or setting to a hard material. A popular one, Portland cement, is a mixture of calcium silicates and aluminates made by heating limestone (CaCO3) with clay (that contains aluminosilicates) in a kiln. The product is then ground to a fine powder. When Portland cement is […]

During the last decades and, especially, throughout the 21st century, expertise is in decline in the USA. This is the subject that the author addresses in his book. I have been interested in it since I learned of its existence because I have the impression that something similar is happening in Spain, although perhaps to […]
