Earth's 'geological thermostat' is too slow to prevent climate change
Rock weathering has helped keep Earth’s climate relatively stable for millions of years, but the process isn't fast enough to keep up with human carbon emissions → Read More
Fetal stem cell treatment for multiple sclerosis shows promising signs
People with progressive multiple sclerosis had higher levels of protective molecules in their spinal fluid two years after being injected with stem cells from a fetus. Whether this translates into improved symptoms over time is unclear → Read More
Genetic map of cells linked to endometriosis could improve treatments
Mapping the cells involved in endometriosis could improve our understanding of how genetics influences the risk of the condition and open the door to new drug targets → Read More
Genetic map of cells that cause endometriosis could improve treatments
Mapping the cells involved in endometriosis could improve our understanding of how genetics influences the risk of the condition and open the door to new drug targets → Read More
Synthetic reproductive cells will help us understand fertility in 2023
Laboratory-grown sperm, placentas and embryos in animals will help us gauge why some pregnancies don't reach full term, but whether these procedures could one day be safe or even ethical in humans is unclear → Read More
How the covid-19 pandemic helped tackle Ebola and monkeypox in 2022
The covid-19 pandemic has improved communication between researchers and officials, and may have even prompted Uganda's first lockdown against Ebola → Read More
Many mosquitoes are now insecticide-resistant in Vietnam and Cambodia
More than three-quarters of Aedes aegypti mosquitoes sampled in Vietnam and Cambodia were from strains that are extremely resistant to pyrethroid insecticides → Read More

Several species of ant have been observed producing a liquid while in a pupal stage that is consumed by ant larvae and adults, and this is likely to occur across all ant species → Read More
Drug clears sleeping sickness parasite from the body in clinical trial
In a small trial, an experimental medicine was 100 per cent effective at ridding the parasite that causes sleeping sickness from the bodies of people with an early to intermediate infection → Read More
Myopia linked to five genetic variants and going to university
In a study of more than 330,000 people, five genetic variants and being educated to university level were together linked to short-sightedness → Read More
The Song of the Cell review: A love letter to life's most basic unit
From the pioneering days of IVF to modern gene editing, Siddhartha Mukherjee's ambitious book explores how far we have come in understanding the cell – and how far we still have to go → Read More

Deaths from liver disease and diabetes have been higher than expected in England and Wales since the coronavirus pandemic began → Read More
Hair follicles grown in the lab in a step towards hair loss treatment
By modifying the embryonic skin cells of mice, researchers created hair follicles that grew up to 3 millimetres long over one month → Read More
Covid jab rates vary in England in children of different ethnicities
In England, 15.8 per cent of children aged 12 to 15 from Gypsy or Roma ethnic groups have received at least one vaccine dose, compared with 83.5 per cent of their counterparts in Chinese ethnic groups → Read More
Gut pain may help to maintain a healthy microbiome in mice
Neurons that transmit pain signals in the gut lining of mice are linked to the production of mucus that may maintain a healthy microbiome → Read More
Human neurons transplanted into a rat's brain influence its behaviour
Researchers propose that rats with human neurons derived from stem cells implanted into their brains could be used to test new psychiatric drugs → Read More
