Eating margarine with Stanol lowers cholesterol by 10 percent

A new study found that consuming three servings of a margarine-like spread containing stanol can lower total and low-density lipoprotein cholesterol levels by up to 10%. The study, which involved over 300 participants with mildly elevated cholesterol levels, showed no adverse effects from using the fortified margarine.

Researchers discover cause of a human immunodeficiency

A team of scientists has discovered that a lack of the B cell linker protein (BLNK) is responsible for an immunodeficiency in mice and a young man with recurring bacterial infections. The study reveals that BLNK plays a crucial role in B lymphocyte development, leading to impaired immune function.

A relative of smallpox is first virus found to invade cells as HIV does

Researchers link myxoma poxvirus to HIV-like immune deficiency in rabbits, supporting a new theory on the origins of HIV resistance. The discovery strengthens the hypothesis that smallpox may have imposed selective pressure for the CCR5 receptor mutation to persist.

Behind the mask

Researchers at Princeton University developed a new patterning technology called Lithographically Induced Self Assembly (LISA), which creates arrays of ultrasmall pillars without the need for a carefully engineered mask. The technique has potential applications in computer memory chips, flat-panel displays, and DNA sorting.

Waste not

The US Navy is developing a new system to treat non-oily wastewater from its vessels, eliminating costs and fines associated with discharging wastewater. The Aerated Non-Oily Wastewater Membrane Treatment System (AMTS) has shown promise in treating graywater and vacuum-collected sewage, allowing ships to remain on their stations longer.

Parathyroid tumors can be removed safely in outpatient procedure

A new study by Johns Hopkins Medicine shows that minimally invasive surgery to remove parathyroid tumors is safe and effective, with a significantly shorter hospital stay and reduced hospital charges compared to traditional open surgery. The procedure also reduces the risk of complications, such as vocal nerve injury.

Dual-earner families are scaling back for kids

A study by Cornell sociologists finds that dual-earner couples are scaling back work to care for families and have more time for themselves. Women are more likely to take on these roles, leading to a 'neotraditional' arrangement where the husband's career is the primary focus.

Researchers at Children's Hospital of Philadelphia play major role in genetic milestone - first full sequencing of a human chromosome

Researchers at Children's Hospital of Philadelphia successfully sequenced nearly 700 genes on chromosome 22, a major breakthrough in genetic medicine. The completed sequence provides the order of 33 million DNA bases, laying the groundwork for further research into genetic diseases associated with this chromosome.
