We often use terms like "warm" and "cold" to describe people. New research shows this may not just be a linguistic oddity; sensations and psychological concepts are actually linked in our minds.

Researchers have found that most fat cells arise from cells in the walls of blood vessels in fat tissue. This insight may lead to new approaches to prevent and treat obesity.

In a finding that may lead to a better understanding of the post-activity exhaustion that strikes many people with muscular dystrophy, scientists have identified a disrupted molecular pathway that leads to fatigue in mice with muscular dystrophy after even mild physical exertion. This fatigue can be relieved by giving the animals a drug that bypasses the disruption.

In the largest effort of its kind, scientists have charted the genetic changes involved in the most common form of lung cancer, implicating more than a dozen new genes.

For the first time, researchers have shown that a direct artificial connection from the brain to muscles can restore movement in monkeys whose arms have been temporarily anesthetized.

Scientists have identified a small antibody fragment that is highly effective at neutralizing the human immunodeficiency virus (HIV). The finding may lead to new treatments against HIV and other viruses.

Scientists have deciphered the complete genetic sequence of the parasite Plasmodium vivax, the leading cause of relapsing malaria. The distinctive genetic features of P. vivax may lead to new tools for preventing and treating relapsing malaria.

Children with convergence insufficiency, a common eye-muscle disorder, responded better to treatments that included weekly office visits to a trained therapist than to strictly home-based regimens, which are more often prescribed.

Scientists have identified a protein that plays matchmaker between 2 key types of immune cells, T and B cells, enabling them to establish long-lasting immunity after an infection.

Researchers have identified 2 new genes—and confirmed the role of a third—that are associated with increased risk of higher levels of uric acid in the blood, which can lead to gout, a common, painful form of arthritis.

Scanning electron micrograph of cancer cell.Rethinking Metastasis
Most cancer deaths result from metastasis, the spread of cancer from a tumor to other parts of the body. Researchers have long thought that metastasis comes at a late stage of cancer. A new study suggests the process may start long before that.

Scientists have developed a new technique to convert adult liver and other cells into versatile stem cells. By using a common cold virus, it sidesteps the cancer-causing potential of a previously developed method using a different kind of virus.

According to a new analysis, nearly a quarter of U.S. women are affected by pelvic floor disorders, a cluster of health problems that causes physical discomfort and limits activity.

Bisphenol A (BPA), a chemical widely used to make plastic food containers, can prevent connections from forming between nerve cells in the brains of monkeys, a new study suggests.

Scanning electron micrograph of microbes that may be found in the gut.Gut Microbes Protect Against Type 1 Diabetes in Mice
Research in mice has found that the trillions of microbes living in the gut can blunt the immune system attack that causes type 1 diabetes. The discovery may shed light on rising rates of type 1 diabetes in developed countries.

For the first time, researchers have identified genetic variations that are strongly associated with kidney diseases disproportionately affecting African Americans.

An advanced imaging technique called virtual colonoscopy can detect most of the large precancerous and cancerous polyps that can be found by the more invasive standard colonoscopy.

Researchers have identified a protein that, when activated, protects against injury to rat hearts. The discovery may lead to treatments for preventing heart damage during procedures such as coronary bypass surgery.
