1. Development of a two-photon excitation light-sheet microscope which achieves low phototoxicity, an extended field of view, and high resolution for the observation of the growth of living organisms 2. Applications of the microscope demonstrate long-term time-lapse observations for a three-day span of the embryonic development of medaka fish
The new findings identify a potential contributor to microcephaly, a birth defect in which the head is underdeveloped and abnormally small.
A researcher at The University of Texas Health Science Center at San Antonio and colleagues are using machine learning to determine which vocalizations of mouse pups are most predictive of autism spectrum disorder when the mice reach puberty.
An estimated one in seven Ohio women of adult, reproductive age has visited a crisis pregnancy center, a new study has found. In a survey of 2,529 women, almost 14% said they'd ever attended a center. The prevalence was more than twice as high among Black women and 1.6 times as high among those in the lowest socioeconomic group.

Many seabirds in the Northern Hemisphere are struggling to breed -- and in the Southern Hemisphere, they may not be far behind. These are the conclusions of a study, published May 28 in Science, analyzing more than 50 years of breeding records for 67 seabird species worldwide.

It's well known that reptiles depend on temperature cues while in the egg to determine a hatchling's sex. Now, researchers writing in the journal Trends in Ecology & Evolution on May 26 say that embryos of many different animal species also rely on acoustic signals in important ways. They call this phenomenon "acoustic developmental programming."

The first species-wide survey of parasite infections across the entire range of the mountain gorilla indicates new challenges ahead for the endangered species as its population grows.
One of the first studies to examine telomere length (TL) in childhood finds that the initial setting of TL during prenatal development and in the first years of life may determine one's TL throughout childhood and potentially even into adulthood or older age. The study also finds that TL decreases most rapidly from birth to age 3, followed by a period of maintenance into the pre-puberty period, although it was sometimes seen to lengthen.

Yan research group has solved a longstanding scientific debate about the mechanism underlying the gamete and embryo transport within the Fallopian tube. Using a mouse model where the animals lacked motile cilia in the oviduct, they demonstrated that motile cilia in the very distal end of the Fallopian tube, the infundibulum, are essential for oocyte pickup. The finding was published in the Proceedings of the National Academy of Sciences (PNAS).
A new study by University of Liverpool ecologists warns that heat-induced male infertility will see some species succumb to the effects of climate change earlier than thought. Currently, scientists are trying to predict where species will be lost due to climate change so they can plan effective conservation strategies. However, research on temperature tolerance has generally focused on the temperatures that are lethal to organisms, rather than those at which organisms can no longer breed.
