Mate choice is important for females, who often invest much more energy in offspring than males. However, being too selective is a bad idea, as they might end up not mating at all. Biologists have wondered for a long time how females optimize their chances. Scientists at the University of Groningen have discovered that mating induces a behavioural change in female flies that makes them more choosy than when they are virgins.

Ten IU School of Medicine researchers out of a team of 11 scientists, are responsible for the findings of a new study they conducted to investigate alternative ways to treat kidney infections.

A University of Houston biomedical researcher is widening the net, looking for symptoms of other proteins -- not just blood - found elevated in colorectal cancer and inflammatory bowel disease. The new biomarkers may one day replace the invasive endoscopy to determine what's going on inside the intestines.

New research suggests that a coronavirus infection alters the biomechanical properties of red and white blood cells, in some cases for months -- a possible explanation for long COVID.

Mayo Clinic researchers are taking a close look at rare cases of inflammation of the heart muscle, or myocarditis, in young men who developed symptoms shortly after receiving the second dose of the Moderna or Pfizer messenger RNA (mRNA) COVID-19 vaccines. Several recent studies suggest that health care professionals should watch for hypersensitivity myocarditis as a rare adverse reaction to being vaccinated for COVID-19. However, researchers stress that this awareness should not diminish overall confidence in vaccination during the current pandemic.

Melkior Ornik, professor in the Dept. of Aerospace Engineering at the University of Illinois Urbana-Champaign, analyzed the same datasets from the United States Holocaust Memorial Museum that were used in a research paper that refutes the number of Holocaust victims from a concentration camp in Croatia. Ornik's rebuttal paper, debunking the researchers' findings, is published in the same journal, IEEE Access.

Combining structural biology and computation, a Duke-led team of researchers has identified how multiple mutations on the SARS-CoV-2 spike protein independently create variants that are more transmissible and potentially resistant to antibodies.

A process that uses heat to change the arrangement of molecular rings on a chemical chain creates 3D-printable gels with a variety of functional properties.

In a new paper experts review the vaccine research and development process and propose areas where reforms could increase access, speed time to market and decrease costs -- from R&D to manufacturing and regulation to the management of incentives like patents and public funding.

Researchers discover a new role for circadian clocks in plants.

In new research published in EPJ ST, researchers demonstrate a robust experimental technique for studying one particular theory for dark energy. Named 'Gravity Resonance Spectroscopy,' their approach could bring researchers a step closer to understanding one of the greatest mysteries in cosmology.

A Rice University lab's reverse approach to making halichondrin B is the shortest route to what it referred to as a rather complex and important molecule and the parent compound of eribulin, the latter being used to treat breast cancer and liposarcoma.

Many drivers use tollways to get from point A to point B because they are a faster and more convenient option. The fees associated with these roadways are higher during peak traffic hours of the day, such as during the commute to and from work.

A new study led by Dan Llano and Baher Ibrahim at the Beckman Institute for Advanced Science and Technology at the University of Illinois Urbana-Champaign discovered a new neuronal circuit that may help control which sensory information is relayed to the auditory cortex. Their paper, 'Corticothalamic gating of population auditory thalamocortical transmission in mouse,' was published in eLife in May 2021.

A new, two-dimensional material from the lab of Rohan Mishra is the first such material to be synthesized and purposefully used.

When regions of the human genome where the DNA can fold into unusual three-dimensional structures called G-quadruplexes (G4s) are located in regulatory sequences or other functional, but non-protein coding, regions of the genome, they are maintained by selection, are more common, and their unusual structures are more stable. Together, these lines of evidence suggest that G4 elements should be added to the list of functional elements of the genome.

Tests of a drug known to stimulate brain activity have shown early success in reducing symptoms of sluggish cognitive tempo in 38 men and women with attention deficit hyperactivity disorder (ADHD.)

A new study highlights the University of Colorado Anschutz Medical Campus as an example of how an academic medical center can turn groundbreaking research into commercial products that improve patient care and public health.The paper, published recently in the Journal of Clinical and Translational Science, focuses on the unique ecosystem at CU Anschutz responsible for these innovations. And it specifically details the campus's collaborative culture and how biomedical research is commercialized.

Despite soybean's high protein and oil content and its potential to boost food security on the continent, Africa produces less than 1% of the world's soybean crop. Production lags, in part, because most soybean cultivars are bred for North and South American conditions that don't match African environments.

A study conducted by the University of Helsinki, the Helsinki University Hospital and the Minerva Foundation Institute for Medical Research shows that the concentration of mitochondrial muscle proteins already decreases markedly in prediabetes. The new finding confirms the significance of muscle mitochondria in the development of type 2 diabetes.
