Existe la posibilidad de que el COVID 19 deje secuelas como las del Alzheimer
MEC Gisela Aguilar Martínez Los expertos creen que el estudio de los cerebros de pacientes con COVID-19 podría conducir a mejores tratamientos para ambas afecciones. Los científicos se esfuerzan por entender por qué algunos pacientes tienen síntomas persistentes, sobre todo, niebla mental, después de padecer COVID-19. Aunque actualmente se sabe poco, ciertos hallazgos podrían aportar […]
Publican una secuencia genómica de alta calidad de la tortuga gigante de Seychelles
Agencia SINC La tortuga gigante de Aldabra (Aldabrachelys gigantea) es una de las dos únicas especies de estos enormes reptiles que quedan en el mundo. Tiene su hábitat en Aldabra —una isla del archipiélago de las Seychelles, en el Índico— y se encuentra en la lista de especies amenazadas. Según los registros fósiles, las tortugas gigantes existieron en todos […]
Ciencia de redes para explicar cómo apareció la complejidad molecular en el espacio
Agencia SINC El origen de la complejidad química en el espacio es, además de una pregunta abierta, un aspecto fundamental para entender los primeros pasos que dieron lugar al origen de la vida. Ahora un estudio internacional, liderado por investigadores del Centro de Astrobiología (CAB, CSIC-INTA), plantea un nuevo acercamiento al origen de la complejidad molecular en el […]
There’s A Scientific Reason Why We Love Dogs So Much | The Dodo
Why we love our dogs, according to science.
A Brief History of Dogs – How We Domesticated Dogs
Dogs are human’s best friend. They’re loyal, hard-working, and eager to please. But how did they get that way? Short answer: Humans. Come along on the journey from prehistoric wolf to portable purse-dogs, as we look at our finest achievement — the invention of dogs!
Your dog’s breed doesn’t determine its personality, study suggests
A new study shows that almost none of the behaviors we associate with dog breeds—from lovable Labradors to pugnacious pit bulls—are hard-wired. Aside from a few ancient traits, environment seems to play a much larger role than pedigree.
Cancer, ageing, and the importance of the tumour microenvironment
Professor Ashani Weeraratna has been studying the cancer microenvironment in her lab for the past 17 years. Taking into account that the tissues in our bodies change as we age is important when researching cancer biology. She hopes that gaining a better understanding of how the growth of cancer cells is affected by their direct […]
Entropy: Embrace the Chaos! Crash Course Chemistry #20
Life is chaos and the universe tends toward disorder. But why? If you think about it, there are only a few ways for things to be arranged in an organized manner, but there are nearly infinite other ways for those same things to be arranged. Simple rules of probability dictate that it’s much more likely […]
Alien life: are we about to find it?
The thought of finding alien life has fascinated people since the time of the ancient Greeks—but developments in astrobiology could be about to turn this possibility into reality. How do you hunt for life beyond Earth—and might this be the decade when we find it?
The Higgs Mechanism Explained | Space Time | PBS Digital Studios
Quantum Field Theory is generally accepted as an accurate description of the subatomic universe. However until recently this theory had one giant hole in it. The particles it describes had no mass! The Higgs field and the Higgs mechanism were proposed long ago in order to give particles mass, but it was only in 2012 […]
How the Higgs Mechanism Give Things Mass
Fermilab physicists really care about the mass of the W boson. They spent nearly a decade recording collisions in the Tevatron collider and another decade analysing the data. This culminated in the April 7 announcement that this obscure particle’s mass seems to be heavier than expected. So why do we care? Because understanding why this […]
¿Pueden los perros detectar por su olfato a personas con COVID-19?
MEC. Gisela Aguilar Martínez. Los perros, se encuentran entre los mejores detectores de olores del mundo animal, ya que tienen hasta 300 millones de receptores olfativos, En el caso de los humanos solo contienen unos 6 millones de receptores olfativos. El cerebro de los perros dedica un 40% más de espacio que el de los […]

The Last Human – A Glimpse Into The Far Future
The future of humanity seems insecure. Rapid climate change, political division, our greed and failings make it hard to look at our species with a lot of optimism and so many people think our end is in sight. But humans always thought they lived in the end times. Every generation assumes they’re important enough to […]
