The protein BICAT3 is one of the most important manganese distributors in plants. If defective, this can have devastating effects on a plant’s growth; its leaves grow significantly smaller and it produces fewer seeds than usual. A team has recently unc…

The behavior of sperm cells is due, in part, to the individual DNA make-up of these cells, rather than only to the genetics of males. The results, which provide a new understanding of the competition among sperm cells to fertilize the egg, have larger …

An analysis of more than 2,400 women who did not have high blood pressure while pregnant found that about 1 in 10 were diagnosed with high blood pressure in the year after childbirth. Almost a quarter of the women who were diagnosed with high blood pre…

Through extensive model calculations, physicistshave reached general conclusions about the internal structure of neutron stars, where matter reaches enormous densities: depending on their mass, the stars can have a core that is either very stiff or ver…

A new study has shown that people in the early stages of their careers were more likely to be impacted by workplace stress during the COVID-19 pandemic than senior colleagues.

Why are there more plant species in some places than in others? Why is diversity highest in the tropics? What is the connection between biodiversity and environmental conditions? To help answer these questions, an international team has reconstructed t…

An international team of researchers have discovered a new genetic variant that is responsible for close to 7% of all cases of diabetes in Greenland. People with this form of diabetes, caused by the high-impact genetic variant, may require special trea…

Adults who frequently worry about being rejected or abandoned by those closest to them are more prone to having false memories when they can see who is conveying the information, a new study suggests.

New research found that in utero exposure to certain flame retardant chemicals may be a risk factor for developing anxiety symptoms in early adolescence.

Children with a severe form of epilepsy should be vaccinated against the flu due to the high risk of seizures being triggered by an influenza infection, according to a new study.

While it’s anatomically impossible for a human to swallow their tongue, a new study shows that cane toads (Rhinella marina) achieve this feat each time they eat. Cane toads swallow prey using a complex pulley system of cartilage and muscle that travels…

Water — which makes up the majority of every cell in the body — plays a key role in how proteins, including those associated with Parkinson’s disease, fold, misfold, or clump together, according to a new study.

Scientists have made bone marrow ‘organoids’ that capture the key features of human bone marrow.

Unlike humans, turtles, lizards and other reptiles — such as crocodiles — do not have sex chromosomes. Their sex is determined based on the environment, which makes them especially vulnerable to climate change. An increase in incubation temperatures …

Financial stress due to the COVID-19 pandemic took a distinct toll on adolescent mental health and contributed to depressive symptoms, according to new research. The study found the effect was most pronounced in low-income adolescents but also affected…

Researchers found disparities in the completion of follow-up concussion care, particularly among pediatric patients who are publicly insured and identify as Black, suggesting barriers to care exist.

An explanation for why flow batteries using the metal cerium in a sulfuric acid electrolyte fall short on voltage could pave the way for better battery chemistry.

Researchers have created a ring-shaped soft robot capable of crawling across surfaces when exposed to elevated temperatures or infrared light. The researchers have demonstrated that these ‘ringbots’ are capable of pulling a small payload across the sur…

A new study finds that small molecules found in most humans’ breast milk may reduce the likelihood of infants developing allergic conditions like atopic dermatitis and food allergies.

Airway inflammation and emphysema are more common in marijuana smokers than cigarette smokers, according to a new study. Researchers said the difference may be due to the way that marijuana is smoked and the fact that marijuana smoke enters the lungs u…
