Researchers at NewYork-Presbyterian Hospital/Weill Cornell Medical Center have identified cancer stem cells as a potential cause of brain tumors. The study aims to develop more accurate and specific cancer diagnoses using these stem cells.
Researchers at UT-ORNL have made progress toward understanding high-temperature superconductivity by studying the behavior of electrons in materials like PLCCO. They found evidence suggesting that magnetism plays a role in creating pairs of electrons, which are crucial for this phenomenon.
A new study from the University of Michigan Comprehensive Cancer Center found that only a third of breast cancer patients discussed reconstruction options with their surgeon. Women who did discuss reconstruction were four times more likely to choose a mastectomy, highlighting the importance of informed decision-making in surgical choices.
Researchers have discovered a new platinum-based compound that is up to 80 times more powerful than current anti-cancer drugs and can target cancer cells with high accuracy using light activation. The compound's stability and non-toxicity in the dark make it an attractive alternative for treating surface cancers.
Researchers genetically engineered a mosquito to release sea-cucumber protein, which impairs malaria parasite development in the insect's gut. The study shows promise for preventing transmission of malaria by disrupting parasite growth and development.
Katherine Freed, a Stevens Institute of Technology undergraduate, won first place in the International ISPE Undergraduate Poster Contest for her project on Impedance Mammography. Her design aims to improve mammographic screening in women under 40 who are not regularly screened.
Researchers from IIBB-CSIC-IDIBAPS have discovered a method to stop and revert idiopathic pulmonary fibrosis in animal models using pneumocytes transplantation. A clinical study will soon be conducted in humans to test the treatment.
A new study estimated the costs of providing comprehensive screening and diagnostic services to under- or uninsured, low-income women. The median cost of screening a woman for breast cancer was $94, while the cost per detected case was $10,566. For cervical cancer, these costs were $56 and $13,340, respectively.
Cornell researchers have discovered silica-rich deposits in Spirit's wake on Mars, providing new evidence for a once-habitable environment. These findings are significant as they suggest a 'local habitable niche' on the planet's surface, supporting microbial life-like conditions.
The American Society for Gastrointestinal Endoscopy has issued guidelines for treating dyspepsia, a condition affecting a fourth of the population. For patients over 50 with symptoms or alarm features, endoscopy is recommended to diagnose structural disease such as peptic ulcer disease and malignancy.
The Biophysical Society has announced the winners of its student travel award for presenting at the Joint Meeting in Long Beach, California. The recipients include researchers from top universities worldwide, who will receive a travel grant and be recognized at a reception.
Researchers at Cornell University found that vibrating mice can signal users to take breaks, but may not change behavior. Ergonomic products like undulating chairs and movable arms for monitors show promise in reducing workplace injuries and improving comfort.
The Biophysical Society has announced the recipients of its international travel grants, who will attend the Joint Meeting in Long Beach. The award aims to foster interaction between American biophysicists and scientists in financially difficult countries.
A team of scientists has discovered that older adults in the Seychelles warbler population help raise their children's grandchildren, providing an alternative route for co-operative breeding. This behavior is thought to be an effective strategy for birds prevented from breeding due to habitat loss.
A team of astronomers has figured out what alien astronomers might see when studying Earth using current and future telescopes. They found that a great deal of information about a planet can be gleaned from its brightness and color changes over time, revealing its rotation rate and weather systems.
A study published in Journal of Clinical Oncology found that nearly 50% of women over 65 with early stage hormone-positive breast cancer discontinue Tamoxifen treatment before five years. Factors predicting premature discontinuation include age, medical illnesses, and lack of radiation after surgery.
Scientists have discovered a possible explanation for Mars' limestone-free climate: sulfur dioxide in the atmosphere. The greenhouse gas interfered with carbonate rock formation, but led to the creation of silicates and sulfites instead.
Most general surgeons fail to discuss breast reconstruction with breast cancer patients before surgery. Researchers found only 33% of eligible patients had this conversation. Younger, more educated patients were more likely to have the discussion, leading to greater willingness to consider mastectomy.
Cornell researchers have proven the polymer trap model theory of sugar transport in plants, which could lead to increased photosynthetic rates and carbon dioxide intake. The study uses genetic engineering to silence genes involved in sucrose polymerization, resulting in a buildup of sugars in leaves.
A Cornell research team used gene chips to study Mycobacterium tuberculosis and found that the bacteria's genes are activated after being engulfed by a macrophage. The study also compared the responses of M. tuberculosis to BCG, finding that BCG may be less capable of protecting itself once inside a macrophage.
A major new study published in Science warns that global warming and acidification are triggering widespread coral disease and stifling coral growth. The researchers argue that drastic action is needed from world leaders to protect coral reefs, which support 100 million people and generate billions of dollars in tourism.
The recently published book 'Conservation of Rare or Little-Known Species' by Island Press offers alternative approaches to conserving rare species. It synthesizes scientific information to apply to real-world problems, making it an excellent resource for land managers, policymakers, and scientists.
The Biophysical Society has announced the winners of the 2008 Minority Travel Awards, which support participation at the Annual Meeting by minority students studying biophysics. The awards are given to ten recipients from universities across the US.
Scientists have found that natural variation is a built-in mechanism to allow the nervous system to explore and maintain motor skills, even in highly practiced skills like those seen in top athletes and musicians. This discovery has implications for rehabilitating patients following strokes and other damage to the nervous system.
Researchers at the University of Texas M. D. Anderson Cancer Center have developed a new scoring system that identifies Myelodysplastic Syndrome (MDS) patients with low-risk disease but poor prospects of survival. The system, applied to 856 patients treated between 1976 and 2005, found that older age, low platelet counts, anemia, and p...
A study of 136 abandoned Romanian children found that those placed in foster care had significantly better intellectual development than those remaining in institutions. The research suggests that early intervention can help prevent long-term developmental problems.
