New insights into the distribution and regulation of meiotic DSB hotspots

A new method, DNA End tailing and sequencing (DEtail-seq), for meiotic DNA double-strand break (DSB) profiling was developed recently.

Study sheds light on unique processes that bestow naked mole-rats’ with eternal fertility

Unlike humans and other mammals, which become less fertile with age, naked mole-rats can reproduce throughout their remarkably long lifespans.

Novel model system helps studying human ovarian biology

Despite the fact that we all start out as an egg cell in one of our mother's ovaries, these human reproductive organs are surprisingly under-studied. Scientists have been working on creating in vitro models of human ovaries so that we can learn more about them and develop treatments for ovarian conditions, but most existing models use a combination of human and mouse cells, which do not faithfully replicate human ovary functions and take a long time to grow in the lab.

Scientists accelerate the development of pure genetic lines by inducing mutation

Iowa State University researchers may have solved a long-standing challenge associated with accelerated development of pure genetic lines.

Elaborating three-dimensional coordination of cell-division site positioning in a cyanobacterium

Cyanobacteria are considered to be the earliest oxygenic photosynthetic organisms present on Earth, and they have played crucial roles in the progress of the environment and life on the planet. Today, cyanobacteria are still found extravagantly in several ecological niches.

Utilizing "cyborg cells" in environment protection and medicine

At the University of California, Davis, biomedical engineers have developed “cyborg cells” that are partially alive.

Chemically attenuated live DNA virus vaccine prevents viral infection

Rutgers researchers have devised a new way to prevent viral infections: a live-attenuated, replication-defective DNA virus vaccine that utilizes the substance centanamycin to create an altered virus for vaccine development.

New framework for developing ecological countermeasures to prevent pandemics

Preserving and restoring natural habitats could prevent pathogens that originate in wildlife from spilling over into domesticated animals and humans, according to two new companion studies.

Investigating the direct effect of mutation on sperm behavior

A team of researchers discovered that the activity of sperm cells is attributable in part to the individual DNA make-up of these cells, rather than just male genetics.

First-ever pedigree provides insights for maximizing genetic diversity in aquarium-bred corals

Corals bred in public aquaria provide novel research opportunities and a healthy stock for outplanting into the wild, essential components of a thriving future for coral reef ecosystems, which support around 25% of all life in Earth's oceans.

New explanation for how chromosome recombination is regulated during sexual reproduction

Scientists from the Max Planck Institute for Plant Breeding Research and the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) suggest an explanation for the century-old mystery of how chromosome recombination is regulated during sexual reproduction.

Understanding insect biology and behavior to develop better pest management tools

Spotted lanternflies send signals with their honeydew excretions, shows a new study. Scientists are researching how this damaging invasive species communicates in order to better manage the pest problem.

The biological advantages of sperm swimming in groups

Sperm actually swim better together when they are swimming against the current. Contrary to common belief, spermatozoa frequently cooperate to go through the female reproductive system in a variety of mammalian species, contradicting the notion that the fastest and fittest male reproductive cell wins the fertilization race.
