Mailing at-home HPV tests may be viable approach for screening hard-to-reach women

Screening women for HPV, or human papillomavirus, is a promising way to help detect cervical cancer early, but many at-risk women go without screening for the virus and without Pap tests that look for abnormal cells on the cervix.

Two types of cellular asymmetry govern shaping of cells into sheets and tubes

Scientists have developed a mathematical model showing that two types of cellular asymmetry, or 'polarity', govern the shaping of cells into sheets and tubes, according to an article in eLife.

New artificial joint restores natural forearm rotation in amputees

A new artificial joint restores important wrist-like movements to forearm amputees, something which could dramatically improve their quality of life.

UNLV researchers suggest new way to classify negative symptoms of schizophrenia

The onset of schizophrenia in young adults can put an immediate halt to life goals, with one set of symptoms being particularly debilitating.

Study uncovers new chemical reaction key to cataract formation

Researchers working to understand the biochemistry of cataract formation have made a surprising finding: A protein that was long believed to be inert actually has an important chemical function that protects the lens of the eye from cataract formation.

Discovery about DNA twists could be crucial in development of new antibiotics

DNA replication is vital to all lifeforms, but in some organisms, it can be prevented by twists in the DNA sequence, called 'supercoils'. If too many supercoils are allowed to build up, cells vital to sustaining life will die.

Scientists use hair-thin fiber endoscope to gain insights into hardly-accessible brain structures

It is the first time, scientists are able to achieve high-resolution observations of neuronal structures inside deep brain areas of living mice - by the use of the most minimally invasive endoscopic probe reported thus far.

Study reveals why mitochondria are often strangely shaped inside the brain

Columbia neuroscientists have discovered why mitochondria, tiny power generators that keep our cells healthy, are often strangely shaped inside the brain.

UT Southwestern researchers discover enzyme that promotes tumor growth

UT Southwestern researchers have found that an enzyme on the surface of some lung cancer cells helps feed the cancer, making it a tempting treatment target.

Researchers map cells in the early human placenta to shed light on pregnancy complications

To treat and prevent pregnancy-related disorders, researchers must understand not only what can go wrong, but when. Complications, such as preeclampsia and pre-term birth, often occur in the second or third trimester, and most research to date has focused on those later stages of pregnancy. But the biological events that lead to these problems could start much earlier.

Researchers reveal previously unknown genetic effect that can raise or reduce risk of heart disease

Atherosclerotic disease, the slow and silent hardening and narrowing of the arteries, is a leading cause of mortality worldwide, responsible for more than 15 million deaths each year, including an estimated 610,000 people in the United States.

Botulinum toxin injections show promise to suppress postoperative atrial fibrillation

Postoperative atrial fibrillation is a common complication, affecting one quarter to one half of all patients following cardiac surgery.

Scientists visualize action of immune cells in response to cancer cell proliferation

As tumors develop, they evolve genetically. How does the immune system act when faced with tumor cells? How does it exert pressure on the genetic diversity of cancer cells? Scientists from the Institut Pasteur and Inserm used in vivo video techniques and cell-specific staining to visualize the action of immune cells in response to the proliferation of cancer cells.

Early-life stress in mice hinders neuron development, causing attention problems

Women are roughly twice as likely as men to develop depression, anxiety and other stress-related problems, including difficulty with attention, and new research from Brown University neuroscientists sheds light on the biological reasons why.

Novel methodology for characterizing neurons could lead to better understanding of brain disease

It takes a lot of cells to make a human brain. The organ houses not only an enormous quantity of neurons (tens of billions), but also an impressive diversity of neuron types. In recent years, scientists have been developing inventories of these cell classes--information that will be essential for understanding how the brain works.

Scientists restore breathing, forelimb function in animal models of chronic spinal cord injury

Millions of people worldwide are living with chronic spinal cord injuries, with 250,000 to 500,000 new cases each year--most from vehicle crashes or falls.

Pitt research team explores whether 'active wrinkles' may help improve synthetic graft design

During a coronary bypass procedure, surgeons redirect blood flow using an autologous bypass graft, most often derived from the patient's own veins. However, in certain situations where the patient does not have a suitable vein, surgeons must rely on synthetic vascular grafts which, while life-saving, are more prone to clot formation that eventually obstructs the graft.

Veterans who suffered multiple traumatic brain injuries are at greater risk for suicide

A new Veterans Affairs study finds that post-9-11 veterans with a history of repeated traumatic brain injuries--versus none--are at much greater risk for considering suicide.

MGH researchers use advanced imaging technology to measure magnetite levels in the brain

Investigators at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital have used magnetoencephalography - a technology that measures brain activity by detecting the weak magnetic fields produced by the brain's normal electrical currents - to measure levels of the iron-based mineral called magnetite in the human brain.

Study provides new understanding of rotavirus infections in newborns

Using a multidisciplinary approach, an international team of researchers from several institutions, including Baylor College of Medicine, reveals that complex interactions between sugars and the microbiome in human milk influence neonatal rotavirus infection.
