What numbers do you see? A new bistable perceptual phenomenon on symbolic numbers

This research described a new perceptual phenomenon of bistability induced by partial occlusion of digital numerals. Results of experiments using visual adaptation indicate that this perceptual bistability mainly originates from mid-level visual processing stages which take part in processing global complex shapes and number forms.

Breakthrough in fertility treatment: Prostaglandin receptors found to promote embryo implantation

A team fhas uncovered a new mechanism that could revolutionize infertility care by promoting embryo implantation. The discovery focuses on prostaglandin (PG) receptors in the uterus that enhance the critical process of decidualization, which is necessary for a successful pregnancy. This finding opens the door to developing new fertility treatments that target these receptors. Read more ›

Discarding the placenta after birth leads to loss of valuable information, pathologists say

Physician-scientists argue that with most placentas discarded after birth, placental pathology is underutilized clinically, should be a routine part of obstetric and neonatal care, and also deserves more research attention. Read more ›

Why petting your cat leads to static electricity

Static electricity was first observed in 600 B.C., but researchers have struggled to explain how rubbing causes it. In 2019, researchers discovered nanosized surface deformations at play. The same researchers now say different electrical charges build up on the front and back parts of a sliding object, creating a current. Read more ›

Metal exposure can increase cardiovascular disease risk

Metal exposure from environmental pollution is associated with increased calcium buildup in the coronary arteries at a level comparable to traditional risk factors, according to a new study. The findings support that metals in the body are associated with the progression of plaque buildup in the arteries and potentially provide a new strategy for managing and preventing atherosclerosis.

Scientists find new epigenetic switch

Researchers have discovered that a DNA modification called 5-formylcytosine (5fC) functions as an activating epigenetic switch that kick-starts genes in early embryonic development. This finding proves for the first time that vertebrates have more than one type of epigenetic DNA mark and sheds new light on how genes are regulated in the earliest stages of development.

Silencing in action: How cells 'repress' genomic remnants of ancient viruses

It is crucial for organisms to be able to control which genes are expressed in which cells and when. Naturally occurring chemical modifications of DNA-binding histone proteins are believed to play an important role in this process; however, it had been unclear whether they play a causal role in instructing gene expression. Researchers have experimentally shown that certain histone sites act as critical control sites that help prevent the spurious... Read more ›

Measuring how much wood a wood shuck shucks with all-new wood shuck food

Researchers want to transform the natural and abundant resource wood into useful materials, and central to that is a molecular machine found in fungi that decomposes the complex raw material into its basic components. Researchers have come up with a test feed for the fungal molecular machine that allows them to observe its close-to-natural action, opening the door to improving it and to putting it to industrial application.

New Alzheimer's studies reveal disease biology, risk for progression, and the potential for a novel blood test

Two new papers by a team of researchers demonstrate that evaluating microRNAs in blood can be used not only to diagnose mild cognitive impairment (MCI) but also, critically, to predict the conversion from MCI to dementia due to Alzheimer's disease. Moreover, the researchers uncovered microRNA candidate molecular biomarkers that associate with current Amyloid, Tau, and Neurodegeneration (A/T/N) Alzheimer's biomarkers. Read more ›

Triplet regimen yields promising response in advanced-phase chronic myeloid leukemia

According to new research, 80% of patients with previously untreated or relapsed/refractory advanced-phase chronic myeloid leukemia (CML) -- including both accelerated or myeloid blast phases of the disease -- or Philadelphia chromosome-positive acute myeloid leukemia (AML) achieved a bone marrow remission when treated with a novel combination of decitabine, venetoclax and ponatinib.
