Scientists discover unreported plant body part
For many, the Thale cress ( Arabidopsis thaliana ) is little more than a roadside weed, but this plant has a long history with scientists trying to understand how plants grow and develop. Arabidopsis was first scientifically described as early…
Hope for infertile men; mice could hold the secret
Male infertility affects more than 20 million men globally and is a contributing cause to around 50% of infertility in couples. Frequently, male infertility is the result of defects in the sperm tail, the flagellum, which allows the sperm to…

How cells measure themselves
Ever since scientists discovered cells under the microscope more than 350 years ago, they have noted that each type of cell has a characteristic size. From tiny bacteria to inches-long neurons, size matters for how cells work. The question of…
How butterflies make transparent wings: MBL scientists see the invisible
WOODS HOLE, Mass. — Many animals have evolved camouflage tactics for self-defense, but some butterflies and moths have taken it even further: They’ve developed transparent wings, making them almost invisible to predators. A team led by Marine Biological Laboratory (MBL)…

A new bacteria, made in Belgium (and UCLouvain)
It all started, when Patrice Cani, FNRS researcher at University of Louvain (UCLouvain), and his team repeatedly observed that a bacterium (called Subdoligranulum) is almost absent in obese and diabetic people, while it is systematically present in healthy people. So,…
Rice fish model of a rare metabolic disorder
Human cells are kept healthy by the activity of millions of proteins. These proteins are modified in different ways, such as by adding sugar molecules to them, which can be crucial for them to function properly. Given this importance, defects…

Scientists explain why echidna penis is ‘weird’
A link between childhood stress and early molars
University of Pennsylvania researchers discovered that children from lower-income backgrounds and those who go through greater adverse childhood experiences get their first permanent molars sooner
Scientists can predict which women will have serious pregnancy complications
Women who will develop potentially life-threatening disorders during pregnancy can be identified early when hormone levels in the placenta are tested, a new study has shown
Experiments show natural selection opposes sexual selection
Natural selection can reverse evolution that occurs through sexual selection and this can lead to better females, new research shows. The study – led by the University of Exeter and Okayama University – examined broad-horned flour beetles, whose males have…
Researchers identify gene linked to congenital heart disease
Researchers have identified a gene that plays a minor role in congenital heart disease, using a combined approach that could aid studies of this and other multigenic diseases
Monarchs raised in captivity can orient themselves for migration, U of G study reveals
While captive rearing may cause temporary disorientation, researchers found if Monarchs are given time in the wild to calibrate their internal compasses they can fly in the proper direction
An ‘atlas’ of the brain’s choroid plexus across the lifespan
New resource for neuroscience maps cell types, secreted proteins, spatial organization, and more
Two-thirds of women don’t meet criteria to discontinue cervical cancer screening
Inadequate screening for older women may contribute to high cancer rates and mortality
Being social generates larger genomes in snapping shrimp
Thanks to ‘jumping’ genes, the genomes of social species have become larger than those of their nonsocial relatives
Chip mimicking bovine endometrium used in study of factors that can jeopardize pregnancy
The device was used for the first time to culture two maternal endometrial cell types, revealing the effects of alterations in glucose and insulin levels in the uterine environment
Odds of stem cell transplant restoring fertility are as random as a coin toss — until now
The odds of restoring fertility through a sperm stem cell transplant are as random as a coin toss. But a team of scientists found a way to rig the outcomes.
A simple model of development reveals shapes of cell lineages and links to regeneration
The model predicts that contrary to belief, cell-lineage maps are unlikely to be tree-like
Fruit fly links sleep problems in autism to glial cells, blood-brain-barrier and serotonin
Bad sleep causes severe health issues and affects our ability to concentrate, memorize, and cope with challenging situations. Individuals with neurodevelopmental disorders such as autism and intellectual disability, frequently suffer from sleep problems. However, little is known about their underlying…
The 8th International Horticulture Research Conference Announcement
To showcase the latest achievements and research progress in the field of horticulture, and promote communication and cooperation among world experts, the 8th International Horticulture Research Conference will be held from July 20 to 22, 2021 in Nanjing, China, and…
Juvenile white-tailed sea eagles stay longer in the parental territory than assumed
Nest protection periods in Germany are not sufficient and need to be extended
Coloring tumors reveals their bad influence
Studies on cancer are limited by the threshold at which cellular transformations become clinically detectable. However, the very initial phase on the way to malignancy is histologically invisible, as the process originates from one single cell. In this early phase,…
