A team led by Prof. Lucio Frydman has found a way to perform multidimensional NMR with a single scan, significantly speeding up molecular studies and enabling the observation of rapid changes in molecules like protein folding. The new method uses a 'slicing' approach, simultaneously performing measurements on multiple thin slices of a ...
A survey of physicians, adults, and health policymakers reveals widespread concern about chronic condition treatment. Over 90% agree that chronic conditions affect everyone, with most stating the current healthcare system is not meeting needs.
The American College of Preventive Medicine rejects popular fad diets like Atkins, promoting instead a balanced diet rich in whole grains, vegetables, and fruit. The College emphasizes that sustainable weight loss and improved health come from healthy eating habits combined with regular physical activity.
A new study by U-M researchers found that the common cold leads to significant economic impact, with Americans spending over $2.9 billion on over-the-counter drugs and nearly $1.1 billion on antibiotic prescriptions for symptomatic relief. The total economic cost of cold-related work loss exceeds $20 billion annually.
Researchers have identified stem cells in human breast cancer that can form new tumors and are resistant to treatment. The discovery may explain why current treatments for metastatic breast cancer often fail, and could lead to the development of new therapies targeted at these cells.
A new study at Stanford University found that dyslexic children's brains begin to function more normally after participating in an eight-week training program. The program helped participants better understand rapidly changing sounds, leading to improved reading scores and brain activity.
Researchers are studying the efficacy of bovine growth hormone in tilapia aquaculture and developing methods for its treatment. Additionally, computer models predict physical impacts of offshore dredging on coastal beaches, and a new publication from Delaware Sea Grant examines port security measures.
A study of 444 managed-care patients aged 12-17 found that adolescents with consistently monitored parents were less likely to engage in alcohol-risk behaviors. The researchers suggest that monitoring may help reduce risk when adolescents are initially exposed to alcohol, but may be insufficient for high-risk behaviors.
Researchers devise new method combining optical trapping and single-molecule fluorescence to study DNA structural and mechanical changes. This technique allows scientists to study rare molecules essential for life and disease development.
A DNA-based computer, award-winning for smallest biological computing device, processes input molecules using spontaneous energy releases to carry out computations without external power. The device contains 15,000 trillion computers performing 330 trillion operations per second with high accuracy.
Research by Professor Erickson suggests that having a variety of casual acquaintances can improve job prospects and overall well-being. People with diverse social networks are more likely to feel in control and have access to valuable information, leading to improved health and happiness.
The repeal of the estate tax may lead to increased wealth inequality, particularly among minority groups, with potential costs for most American families. The tax reduction is expected to decrease philanthropic giving by up to 12 percent annually due to lower inheritance donations not being taxed.
Computer scientists Pedro Diniz and Joonseok Park are developing programming tools to automatically synthesize near-optimal chip architectures for flexible chips. Their techniques enable FPGAs to utilize available transistors more effectively for irregular applications, outperforming current processor architectures in some cases.
Researchers found that progesterone receptor knockout mice showed a complete lack of infanticide and exhibited active paternal care, frequently contacting and retrieving pups. In contrast, control mice committed 74% infanticide and displayed less paternal behavior.
Researchers found that cardiac surgery patients with the factor V Leiden gene variant lost less blood and required fewer transfusions than those without the mutation. The study suggests a new approach to personalized medicine, tailoring therapies based on individual genetic risk factors.
Argonne researchers have created powerful stem cells that can morph into various cell types, offering a practical alternative to embryonic stem cells. The breakthrough allows for the production of pluripotent stem cells from adult blood cells, which can potentially treat diseases such as cancer and neurodegenerative disorders.
The Prevention of Recurrent Venous Thromboembolism trial found that low-dose warfarin prevents episodes of deep vein thrombosis and pulmonary embolism with a significant reduction in risk. The study showed no major bleeding complications, making it an effective and safe treatment option.
Researchers from the University of Washington and Southern Methodist University conclude that climate change, not humans, was responsible for the extinction of Pleistocene mammals in the New World. The study found no evidence linking Clovis people to the extinctions, contradicting previous 'overkill' hypothesis.
A new clinical trial found that a drug called milrinone strongly reduces the risk of heart failure in children after cardiac surgery. The study involved 238 patients and showed that high-dose milrinone is 55% less likely to cause low cardiac output syndrome compared to a placebo.
A 12-week study in Baltimore evaluated nevirapine for HIV prevention in adults at high risk, showing no serious side effects or new infections. The researchers discovered that the three lower doses of nevirapine provided sufficient blood levels to potentially prevent HIV infection.
A study published in Child Development found that teenagers in high-use schools are three times as likely to follow their peers' smoking behaviors compared to those in low-use schools. The researchers suggest that school-based programs may be effective in reducing tobacco and alcohol use among teens.
Researchers have successfully created a giant self-assembled liquid crystal lattice using hundreds of thousands of highly branched molecules. The structure, which consists of discrete microscopic spheres linked together, has a repeat unit size comparable to spherical virus particles isolated from plants.
