In the fight to cure human immunodeficiency virus (HIV), researchers have been dealt a blow. A new study shows that the pool of inactive HIV viruses that lingers silently in a patient’s body is larger than expected.
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.
A recent study by a University of Missouri researcher shows that resveratrol, a compound found in grape skins and red wine, can make certain tumor cells more susceptible to radiation treatment. This research, which studied melanoma cells, follows a previous MU study that found similar results in the treatment of prostate cancer.
A new study finds that some people are genetically predisposed to see the world darkly. The study finds that a previously known gene variant can cause individuals to perceive emotional events more vividly than others.
A dollop of peanut butter and a ruler to test for smell sensitivity can be used to confirm a diagnosis of early stage Alzheimer’s disease, researchers have found.
With high-tech optical tools and sophisticated mathematics, researchers have found a way to pinpoint the location of specific sequences along single strands of DNA, a technique that could someday help diagnose genetic diseases.
A new laser, the Supra Scan Multi-spot Laser, is helping experts provide better treatment for eye diseases. This advanced laser can prevent blindness for some patients with serious conditions. The first patient received treatment from the laser for proliferative diabetic retinopathy on July 22.
Scientists have moved closer to developing a universal flu vaccine by using the 2009 swine flu pandemic to study why some people seem to resist severe illness. Researchers asked volunteers to donate blood samples just as the pandemic was getting underway and also asked the volunteers to report any symptoms they experienced over the next two flu seasons.
Researchers at MIT have developed a microfluidic device that mimics the process of extravasation, showing the flow of cancer cells through a system of blood vessels. The extravasation process is a crucial step in cancer metastasis that, until now, has been unclear.

A small pilot study shows for the first time that changes in diet, exercise, stress management and social support may result in longer telomeres, the parts of chromosomes that affect aging. It is the first controlled trial to show that any intervention might lengthen telomeres over time.
Previously believed to be only man-made, a natural example of a functioning gear mechanism has been discovered in a common insect- showing that evolution developed interlocking cogs long before we did. The juvenile Issus has hind-leg joints with curved cog-like strips of opposing “teeth” that intermesh, rotating like mechanical gears to synchronize the animal’s legs when it launches into a jump.
A research team has become the first to make adult cells from a living organism retreat in their evolutionary development to recover the characteristics of embryonic stem cells. They have also discovered that these embryonic stem cells have a broader capacity for differentiation than those obtained via in vitro culture.
Delivery of cancer care in the U.S. is facing a crisis stemming from a combination of factors—a growing demand for such care, a shrinking oncology work force, rising costs of cancer care, and the complexity of the disease and its treatment, says a new report from the Institute of Medicine.
