“By identifying a new population of neurons activated by oxytocin, we have uncovered one way this chemical signal influences interactions between male and…
The research, published by the Journal of the American Chemical Society, was led by Jamal Musaev, a theoretical chemist at Emory University, and Ken Itami, an…
What could the natural diversity and beauty of plant leaves have in common with one of mankind’s greatest creative inventions, the violin? Much more than you…
In 1995, 16-month old Kumari, the first Asian elephant born at the National Zoo in Washington, DC, died of a then-mysterious illness. In 1999, Gary Hayward of…
Biological evolution is in general based on the progressive adaption of traits through natural or sexual selection. However, ever so often, complex traits with…
A new discovery suggests that the number of human genomic loci that might be coding for tRNAs is nearly double what is currently known. Most of the newly…
A team of ETH Zurich researchers led by professors Nenad Ban and Ruedi Aebersold have studied the highly complex molecular structure of mitoribosomes, which are the ribosomes of mitochondria. Ribosomes are found in the cells of all living organisms. However, higher organisms (eukaryotes), which include fungi, plants, animals and humans, contain much more complex ribosomes than bacteria. In eukaryotes, ribosomes can also be divided into two types: those in the cytosol – which comprises the majority of the cell –…
The researchers found that giving this new fat, or lipid, to mice with the equivalent of type 2 diabetes lowered their elevated blood sugar, as detailed…
The introduction of foreign DNA into human cells through a process known as ‘transfection’ allows scientists to study gene expression in the laboratory and…
Reliable batch-to-batch formation is crucial for crystalline, active pharmaceutical ingredients as two different polymorphs of the same drug may function very…
Cells are generally able to repair spontaneous damage that arises in their genetic material. Unfortunately, the DNA repair process is not perfect and…
The scientists believe a related system may be at work in humans during the progression of colorectal cancer due to the observation of similar genes and…
University of Utah biochemists have reported a new drug discovery tool against the Ebola virus. According to a study published in this week's online edition of
At the heart of this pathway lies PPARγ (peroxisome proliferation-activated receptor gamma), a protein that regulates glucose and lipid metabolism in normal…
A molecule that helps cancer cells evade programmed self-destruction, an internal source of death, might also help malignant cells hide from the immune…
“Exosomes are minuscule membrane vesicles — or sacs — released from most, if not all, cell types, including cancer cells,” said Yong Zeng, assistant professor…
