New drugs target HIV's deep pocket

Researchers have developed a new family of chemicals that bind specifically to the gp41 pocket, halting HIV's ability to infect cells. The compounds, created using mirror-image phage display, show promise as potential oral treatments for HIV, with advantages including reduced cell membrane penetration and lower likelihood of resistance.

Alcohol researchers confirm molecular culprit of alcohol-induced liver damage

A study found that tumor necrosis factor-alpha (TNF-alpha) plays a crucial role in early liver damage caused by alcohol consumption. The researchers used gene knockout technology to show that TNF-alpha mediates the development of liver injury, leading to potential new drug therapies for conditions affecting millions of Americans.

Some Neanderthals practiced cannibalism, shows find from French cave, as reported in the 1 October issue ofScience

The discovery of 78 Neanderthal bones at Moula-Guercy suggests that European Neanderthals practiced cannibalism, systematically defleshing and breaking apart the bones to remove marrow and brains. The abundance of natural resources available at the site makes survival-based cannibalism unlikely.

Researchers find elevated cholesterol is risk factor for preeclampsia

Elevated cholesterol levels are associated with an increased risk of preeclampsia, a pregnancy complication that can lead to seizures, liver or kidney failure, and premature delivery. Women with high cholesterol before pregnancy are more likely to develop the condition, which affects thousands of women each year.

Study confirms protein culprit in alcohol-induced liver disease

Scientists have identified TNF-alpha as a major contributor to early liver injury from long-term alcohol consumption, paving the way for new treatments. The study used gene knockout technology and found that mice lacking TNF receptors fared better on measures of liver injury after alcohol exposure.

Rett Syndrome traced to defective gene 'silencer'

Researchers at Howard Hughes Medical Institute uncover the first human disease linked to a defect in the MECP2 gene silencer mechanism. The discovery provides new insights into nervous system development and may lead to new treatments for Rett Syndrome, a neurodevelopmental disorder causing mental regression in young girls.

Normal cellular enzyme becomes marker for Alzheimer's disease

Researchers have identified a new molecular marker for Alzheimer's disease, a normal cellular enzyme called casein kinase-1 (CK-1), which accumulates in nerve cells damaged by AD. CK-1 levels were found to be abnormally high in vacuoles within the hippocampus region of AD brains.

Researchers solve vision mystery

A study of infants with dense cataracts found that visual stimulation, not brain development, is responsible for the five-fold visual improvement within six months of birth. Babies' vision improved rapidly after cataract removal and contact lens fitting, with some developing 20/20 vision.

Researchers discover location of a testicular cancer gene

A team of researchers has identified a genetic link on mouse Chromosome 19 that controls inherited susceptibility to testicular cancer. The discovery uses a new genetic technique called chromosome substitution, which may lead to improved understanding and treatment options for the disease.
