New demographic data on humans, animals and plants for the first time unveils such an...
Scientists have found that cells known primarily for tempering immune response also exist in...
Using a powerful gene-hunting technique, researchers report they have identified a gene involved...
A new approach developed by researchers could enable the most detailed x-ray images ever— including clear views of soft tissue without any need for contrast agents.
With few exceptions, cells don’t change type once they have become specialized. However, new findings have identified a method for changing one cell type into another in a process called forced transdifferentiation.
A byproduct of cholesterol functions like the hormone estrogen to fuel the growth and spread of the most common types of breast cancers, researchers report.
Hearing the term “paralysis” often conjures the image of someone with a spinal cord injury. While an estimated 1.2 million Americans do suffer from paralysis due to a spinal cord injury, the impact of paralysis is even more widespread, with nearly 5.6 million affected overall, according to the Reeve Foundation.
Scientists have shown that if oxytocin is administered to men and if they are shown pictures of their partner, the bonding hormone increases the attractiveness of the partner and strengthens monogamy.
A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure.
One of the smallest parts of the brain is getting a second look after new research suggests it plays a crucial role in decision making.
Using Drosophila melanogaster, researchers discovered that during multiple cell migrations a single cell can act as leader, dragging the others with it.
Researchers report that the deletion of any single gene in yeast cells puts pressure on the organism’s genome to compensate, leading to a mutation in another gene.
What may be the oldest complete fossil on Earth paints a smelly but colorful picture of our microbial ancestors from nearly 3.5 billion years ago. The fossil is the remains of what once was a purple-and-green slimy, smelly mat of single cell microbes that worked, lived and even communicated together in what is an awful lot like a prehistoric microscopic society.
In biomedical research, access to human tissues is of central importance in studying a disease or condition, and ultimately in developing drugs and looking for cures. For this reason, scientists are rolling out an innovative project to develop an extensive Research Registry and Specimen Bank, a unique biobank.
Two knee surgeons have discovered a previously undescribed ligament in the human knee. The ligament appears to play an important role in patients with anterior cruciate ligament (ACL) tears.
A multi-institutional research team, led by Johns Hopkins engineers, says it has solved the puzzle of why animals push in directions that don’t point toward their goal, like the side-to-side sashaying of a running lizard or cockroach.
For nearly 300 years, investigators have known that body temperature follows a circadian, or 24-hour, rhythm, with a peak during the day and a low at night. Now, researchers explain how body temperature rhythms are synchronized while maintaining the ability to adapt to changes in environmental temperature no matter the time of day or night.
Using cells from the stem of a seedling as a model system, biologists are seeking to understand the molecular mechanisms that organize and pattern the hundreds or thousands of microtubular “bones” of the plant cytoskeleton.
As researchers develop new therapies based on making specific cells to do specific things, getting the right message to the right group of cells at the right time remains a major challenge. Now, researchers have developed a way to deliver a light signal to specific tissues deep within the body.
Researchers have devised a hair restoration method that can generate new human hair growth, rather than simply redistribute hair from one part of the scalp to another.
A colorful wheel developed bioengineers to visualize protein interactions has won an international competition for novel strategies to study the roots of breast cancer.
DNA analysis conducted by a British genetics professor suggests that he has solved the mystery of the Abominable Snowman— the elusive ape-like creature of the Himalayas. He thinks it's a bear.
Living standards have risen significantly in the developed world over the past 50 years, so why aren’t we happier than our grandparents? A new study argues that the psychological benefits from income rises are wiped out by much smaller income losses.
Scientists have long believed that the neurons that are responsible for relaying touch signals to the central nervous system followed a linear path to the brain with a "labeled-lines" structure. But new research on mouse whiskers reveals that the sensory system's wiring diagram doesn't have a set pattern.
Using real-time scans of the brain, researchers found a brain region in which patterns of neural activity play a role in recognizing faces.
In the battle against antibiotic resistant bacteria, McMaster researchers have found resistance itself is a successful pathway for discovering new antibiotic drugs. "In essence, we’ve made resistance useful instead of a scary problem," said Gerry Wright, professor and scientific director of the Michael G. DeGroote Institute for Infectious Disease Research.
New research from the University of California, Davis, shows that the tiny proportion of a cell's DNA that is located outside the cell nucleus has a disproportionately large effect on a cell's metabolism. The work, with the model plant Arabidopsis, may have implications for future treatments for inherited diseases in humans.
University of Utah researchers have found that deficiency of an antioxidant response protein called nuclear erythroid-2 like factor-2 (Nrf2) delays or prevents hypertrophic cardiomyopathy, a type of a heart failure in which the heart muscle grows abnormally thick.
