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.

Strawberries pollinated by solitary bees that ingested pesticides were smaller

Solitary bees that ingested the pesticide clothianidin when foraging from rapeseed flowers became slower. In addition, the strawberries pollinated by these bees were smaller. This is shown by a new study from Lund University in Sweden.

Clothianidin affects bee behavior and pollination performance

It is well known that strawberries whose blossoms have been visited by bees grow larger; however, it is not yet understood how neonicotinoid pesticide exposure to bees affects strawberry development.

Insects are more susceptible to global warming than previously thought

Insects have weak ability to adjust their thermal limits to high temperatures and are thus more susceptible to global warming than previously thought.

Light-sensitive molecule can interpret moonlight to synchronize the reproductive cycles of marine life

How animals are able to interpret natural light sources to adjust their physiology and behaviour is poorly understood.

Scientists demonstrate a potential new route for the generation of genetic diversity in corals

In a discovery that challenges over a century of evolutionary conventional wisdom, corals have been shown to pass somatic mutations – changes to the DNA sequence that occur in non-reproductive cells – to their offspring.

Research provides better understanding of the Prussian carp's peculiar, efficient reproductive strategy

The Prussian carp is considered one of the most successful invasive fish species in Europe. Its ability to reproduce asexually gives it a major advantage over competing fish.

Analyzing and acknowledging HIV protein may result in new treatments, study reveals

Researchers from Rutgers University and the Salk Institute defined the molecular structure of the HIV Pol polyprotein, a protein that helps the virus propagate and spread throughout the body, in an exploration that could lead to the formation of potential treatments for more than 40 million HIV patients globally.

Rochester biologists show a selfish “supergene” using population genomics

There are several “selfish genetic elements” in the human genome that do not appear to benefit their hosts but instead appear to exist only to reproduce themselves.

New insights into early embryo development and origin of disease

The biochemical signals that determine the formation of the body pattern in the primate embryo have been found by scientists. This will direct research into human birth abnormalities and pregnancy loss.

Scientists discover that most synonymous mutations are strongly harmful

University of Michigan scientists reveal that most synonymous mutations are severely damaging in a study published in Nature that entailed genetic manipulation of yeast cells in the lab.

Researchers take a deep dive into the genetic origins of mustelid physiological and behavioral range

Within the order Carnivora, Mustelids are the most ecologically and taxonomically varied family. They inhabit a range of natural niches, from the tayra in the tropics to the wolverine in the subarctic, and have developed species-specific features relating to their feeding, reproductive strategy, and shape.
