Unusual sex chromosomes of platypus, emu and duck
Unusual sex chromosomes of platypus, emu and duck
Three papers unveil the extraordinary diversity of animal sex chromosomes The sex chromosomes genetically define the developmental fate of an embryo to become a male or a female individual, and usually appear as one pair of morphologically different chromosomes between sexes. For example, women have one pair of XX chromosomes, while men have one pair of XY chromosomes.

Deadly parasites create unique cellular structures to survive
Scientists have solved a key parasitic puzzle, revealing the unique and complex structures toxoplasmosis and malaria parasites make in order to survive in different hosts. The new study, led by the University of Glasgow in collaboration with the University of Stockholm, and published , details how certain parasites can create unique cellular structures to control how they create energy and thus survive in different hosts.

Simple bioreactor makes 'gut check' more practical
Simple bioreactor makes ’gut check’ more practical
Rice, Baylor device mimics intestines to show how invading bacteria cause disease Rice University and Baylor College of Medicine researchers have found a way to mimic conditions in intestines, giving them a mechanical model for the real-time growth of bacterial infections. In a new study, they demonstrate a lab tool that simplifies simulations of the human intestine, making it more practical to find treatments for diseases like infectious diarrhea.

What Neural Networks Playing Video Games Teach Us About Our Own Brains
When you are driving a car, your brain is taking in an enormous amount of visual information and using it to make driving decisions, such as when to brake or change lanes. The brain needs to determine what kind of information in your field of view is necessary for making these decisions. For example, the position of another car is very important, but a cloud in the sky or the color of that car does not really have an impact on the way you drive.

One antibody blocks dangerous effects of dengue virus infection, offering a potential path to prevention
One antibody blocks dangerous effects of dengue virus infection, offering a potential path to prevention
New research reveals how one antibody blocks dangerous effects of dengue virus infection, offering a potential path to prevention A team of researchers has discovered an antibody that blocks the ability of the dengue virus to cause disease in mice. The findings open the potential for developing effective treatments and designing a vaccine for dengue and similar diseases.

The wings of a “genetic bird” protect us against viruses
Researchers have demonstrated that every population can protect itself against a broad range of viruses thanks to the two most diverse HLA immune genes in humans. Do populations from different geographic regions have the same potential for defending themselves against pathogens and against viruses in particular? An analysis of human genomes, especially the HLA genes responsible for the so-called "adaptive" immune system, provide some possible answers to this question.

Neuronal circuits for fine motor skills
Neuronal circuits for fine motor skills
Writing, driving a screw or throwing darts are only some of the activities that demand a high level of skill. How the brain masters such exquisite movements has now been described in the journal "Nature" by a team of researchers at the University of Basel and the Friedrich Miescher Institute for Biomedical Research.

Scientists create first computational model of entire COVID-19 virus
Pioneering multiscale model allows researchers to plug in and better understand information as new discoveries are made Researchers at the University of Chicago have created the first usable computational model of the entire virus responsible for COVID-19-and they are making this model widely available to help advance research during the pandemic.

New COVID-19 test gives positive result in just a few minutes
A new COVID-19 test that reduces testing time from 30 minutes to less than five and delivers accurate results has been developed by researchers at the University of Birmingham. The researchers believe their method could deliver a test that is not only fast but also sufficiently sensitive. The test does not require samples to be treated at high temperatures, and it can be performed using standard laboratory equipment, making it readily deployable.

How an Embryo Tells Time
It is estimated that the majority of pregnancies that fail do so within the first seven days after fertilization, before the embryo implants into the uterus. In this time period, a complicated cascade of events occurs with precise timing. One particularly important process is called polarization, when the individual cells that make up the embryo become asymmetrical.

Molecular mechanism involved in Huntington’s neurodegeneration
These images show the nucleus of neurons in the CA1 region of the hippocampus with a marker for lamina B1. It shows the altered morphology of the nuclei of neurons in the R6/1 mouse, a model of Huntington's disease. Recerca Protein alteration in the family of lamins causes several diseases, known as laminopathies, such as progeria or precocious ageing.
