Rzeczywiste i iluzoryczne kontrowersje wokół ciąży
Autor tekstu: Marta Koblańska, 30 maja 2025. Zdjęcie: Zapłodnienie. Licencja TBIT, Pixabay Im cięższa jest wada genetyczna zarodka i późniejszego płodu, tym szybciej jest on eliminowany z organizmu kobiety. Lżejsze wady z reguły pozwalają na donoszenie ciąży, choć nie oznacza to, że dziecko przeżyje po urodzeniu – mówią eksperci z zakresu ginekologii i położnictwa oraz neonatologii.…

Why are genes less similar better for studying diseases?
Photo: Baboon, Clker-Free-Vector-Images, Pixabay Baboons show greater resilience to diseases despite their diverse genome, whereas humans, with a singular set of chromosomes, exhibit increased susceptibility – according to a new study published in ,,Cell Genomics”. Genetic variations differ in humans as a whole body or within the body in certain tissues. Genetic variation, simplifying, is the number of chromosomal…

What influences cognition? The exchange in purine bases and amino acids in the brain.
Photo: Adenine structure, one of the purine bases, specifically connects to thymine via hydrogen bonding in DNA and uracyl in RNA, as discovered by James Watson and Francis Crick in the 50s. Credit:kropekk_pl Of the about 20,000 metabolites discovered so far in human blood serum, over 1,300 and 140 lipids have been observed to profile the brain’s uptake and…

Why does mitochondrial disruption cost so much?
Photo: Mitochondrium, SkieTheAce, Pixabay Does evolution know the paths of the past and future? That’s possible according to new research published in ,,Cell”. How? By tracking the transport of signals and nutrients inside a cell. The mitochondrion is a cell organelle with a separate from the cell nucleus genetic material inherited only from a female…

Why do women put on weight during pregnancy? Mouse example
Photo: Sunflower, Joshrowe, Pixabay Why do women gain more weight during pregnancy than the size of the fetus? Because of small intestine growth apart from the growing off-spring. Although pregnancy is a natural stage for females and generally does not require specific treatment if both the mother and child are healthy, the bodies of many…

Why is fentanyl so perfect cure for increasing pain grade?
Photo: Rowan berry, chulmin1700, Pixabay Fentanyl, a currently popular opioid, effectively relieves pain by enhancing neuronal responses in selected brain pathways, according to a new study published in Neuron. Pain grades have been classified by the World Health Organization in 1986 as more and more humans started to get cancer. The author of the first…

Are wind farms causing harm to cognitive functioning? Balancing between health and clean energy
Wind turbine, Photo: Viniane6276, Pixabay Wind farms are a substantial source of clean energy needed for green transformation. Is the noise they produce harmful for people and nature or not? Clean energy from various renewables may decrease dependence on fossil fuels as a major energy course. There are several ways to get the so-called green…

What makes aging more friendly? X chromosome
Photo: Blueberries, congerdesign, Pixabay The later activation of the X chromosome may enhance cognitive function, which could partly explain why women tend to have longer lifespans. Each of us inherits our genetic background from our parents, grandparents, and even distant ancestors that we may have forgotten. Humans have 23 pairs of chromosomes, with one set…

Paradox of evolution. What can capture and unleash us from Earth?
Photo: Molecules, wastedgeneration, Pixabay A tiny insertion of a highly charged, binding potential helix into the space of RNA after the prokaryote code was lost or removed could change the direction of life’s evolution. RNA is a single-strand of ribonucleic acid, which is more primordial to DNA built with two strands and slightly different bases.…

Losing and awakening heartbeat. What is sleep in real?
By Marta Koblańska, February 21, 2025 Photo: This model suggests that the physiological processes influenced by fluctuations in norepinephrine (NA) during NREM sleep—particularly those related to memory consolidation and glymphatic clearance—function best when these fluctuations occur approximately every 50 seconds. Authors: Anita Lüthi, Maiken Nedergaard. Sleeping is a kind of disengagement from the environment to…

Ancient beliefs about life cycles may be true, as chemistry sets up the foundations for environmental processes crucial for emerging life on Earth. One of the greatest ever philosophers, Baruch/Benedictus Spinoza, claimed that Earth…
