“How is plant growth controlled?” and “What is the basis of variation in stress tolerance in plants?” were among the 125 most challenging scientific questions, according to the journal Science in 2016. Strigolactone (SL) is an important plant hormone that plays essential roles in regulating branch number, a key growth and development trait for plants. Recently, scientists from the Chinese Academy of Sciences (CAS) have uncovered the mechanism behind SL perception and its key role in the tillering response to nitrogen. The “gas and brake” mechanism of SL perception allows “smart and flexible” regulation of the duration ...

Niigata, Japan - A new nationwide study from Japan spanning a 14 year study period has revealed an increasing trend of overweight and obesity in patients with the incident end-stage kidney disease (ESKD). Although, underweight individuals remain prevalent in this patient population, the study highlights that excessive weight and obesity in patients with the incident ESKD is a shared global challenge. Consequently, the study suggests the need for public health strategies to address the global obesity epidemic as well as underweight individuals in incident ESKD populations. “The global ...

Clinics and hospitals currently defer medication abortion until ultrasound confirms a pregnancy inside the uterus. However, a large international study led by researchers from Karolinska Institutet now indicates that treatment can be equally effective and safe even before the sixth week of pregnancy. The study is published in The New England Journal of Medicine. 35,550 abortions took place in Sweden in 2023, over 60 per cent of them before the end of the seventh week of pregnancy. Often, the procedure is held off until intrauterine pregnancy is confirmed by vaginal ultrasound to rule out the possibility of an ectopic pregnancy, in which the embryo attaches ...
