‘Like working in a kettle’: France’s overcrowded prisons swelter under historic heatwave
The deadly heatwave sweeping France has once again exposed the structural problems of the country’s chronically overcrowded prisons, with groups of three or four detainees crammed into airless cells built to hold a lone prisoner. Analysts and prison staff alike have criticised a
Immune ecotypes may explain multiple myeloma outcomes missed by disease staging
Researchers at The University of Texas MD Anderson Cancer Center have created a comprehensive single-cell map of the tumor immune microenvironment in multiple myeloma and its precursor conditions. The study provided insights that may explain why patients with similar diagnoses of
Stem cell science unlocks more mysteries of the menstrual cycle
Amid all the advances in modern medicine, much of the science behind a woman's menstrual cycle remains mysterious, so a team at Hudson Institute of Medical Research is aiming to change that. Professor Caroline Gargett is an expert in the human endometrium, the highly regenerative
The skin microbiota—billions of microbes that protect or harm
A constant interplay takes place on the surface of the body between cells, the immune system and the skin microbiota. We do not notice it—until the balance is disturbed. Then it becomes clear that the outermost layer of the skin plays a crucial role in the well-being of the whole
Frenchman convicted in missing body case confesses to killing his wife, lawyer says
Cédric Jubillar, a painter and plasterer who was sentenced last October for killing his wife Delphine, has finally confessed to the murder from his prison cell, his lawyer said Monday. The 38-year-old said he was ready to tell investigators the location of his wife's body, which
Syria arrests IS group-linked suspects over Damascus bombings during Macron visit
Syrian authorities said on Thursday they had arrested several suspects accused of carrying out a series of bombings in Damascus including attacks during French President Emmanuel Macron's visit this week. The interior ministry said security forces dismantled the entire cell, whil
Mediterranean-inspired diet with added methionine extends healthy lifespan in mice
A plant- and fish-based, low-protein diet paired with small amounts of an amino acid commonly found in eggs, meat and dairy increased healthy lifespan and decreased frailty and fat mass in mice, according to a new USC study published in the journal Cell Metabolism.
What one sleepless night does to brain connections and why sleep may reset them
A night without sleep produced increased markers of connections between brain cells, showing that sleep in humans may be important for restoring cellular balance in the brain, according to a study published in PLOS Biology by David Elmenhorst from the Forschungszentrum Jülich Ins
Hope for spinal injuries as pigs walk again after experimental gel treatment for severed s
In humans and other mammals, spinal cord injuries can be devastating, leading to permanent loss of movement, sensation and bladder control. When severed axons (the long fibers that carry messages between nerve cells) cannot regrow, a dense scar forms, preventing nerve signals fro
Diacylglycerols for cleaner oil processing, functional foods and medical nutrition
Fats and oils are essential to life. They provide energy, support the absorption of fat-soluble vitamins, contribute to the structure of cell membranes, and give foods their flavor, texture and mouthfeel. Yet the way fats are produced, processed and consumed is changing. Food man
Blocking a female-only GABA signal that helps glioblastoma evade immunity may boost surviv
Researchers have identified a critical biological difference in how glioblastoma develops in male and female laboratory models, pinpointing an immune pathway that fuels tumor growth only in females. The study shows that the neurotransmitter GABA boosts the cancer-protecting activ
