A federally funded study reveals that China trade has led to massive job shifts, with over 34,900 jobs lost in the US and stagnating wages. The study also shows that large companies are targeting low-cost markets in China and abroad, contrary to expectations of rising wages and living standards.
A large population-based study in Nordic countries found no increased cancer risk for siblings of children with common non-inheritable cancers. Siblings younger than 10 years were at higher risk, but this decreased with age. The study suggests that childhood cancer is not a predictor of increased cancer risk in siblings.
Researchers discovered MTBE in over 70% of gasoline samples across Indiana, Illinois, and Michigan, raising concerns about its impact on drinking water. The widespread presence of the chemical, used as an oxygenate to reduce emissions, is attributed to tankers, storage tanks, and pipelines that carried reformulated gasoline.
A new protein called Fbw7 has been found to control cyclin E levels in cells, which is associated with cancer progression. The study suggests that the absence of Fbw7 in breast cancer-derived cell cultures may indicate a tumor suppressor gene, suggesting its potential role in preventing malignant change.
Researchers found that antioxidants like vitamin C can significantly reduce free radical generation and skin damage. Vitamin C was the most effective quencher, accumulating in the skin to neutralize free radicals.
Researchers at the University of Illinois discovered that fluids with high enough speed can slip over smooth solid surfaces, unlike textbook predictions. This phenomenon has significant implications for applications such as microfluidic devices and lubrication in computer hard drives.
Patients with dementia in the middle stages are five times more likely to experience intense emotional distress than those in early or late stages. The study found that caring for personal hygiene, particularly invasive care, triggers acute distress. Strategies like supervision and environmental changes can help mitigate reactions.
Researchers at Virginia Tech use in-situ infrared spectroscopy to observe and control the synthesis of carbon fiber precursors. The study demonstrates the benefits of real-time observation in enhancing reactivity and efficiency in the conversion process.
Researchers at the Gladstone Institute have discovered a new pathway that regulates the activity of NF-kB, a protein controlling key inflammatory and immune responses. The study reveals how acetylation and deacetylation control NF-kB's ability to trigger biological processes.
A new study from Georgia Institute of Technology suggests that buoyancy plays a crucial role in causing hot, partially molten rocks to rise and erupt through the surface at mid-ocean ridges. This finding contradicts the long-held assumption of passive sea-floor spreading.
A study of 100 middle-class Indian fathers found they are more socially connected to their families, engaging in lengthy discussions with their children on various topics. In contrast, American fathers tend to be less engaged and absorbed in their work lives.
A study of 102 heart attack patients reveals that 40% experienced PTSD symptoms, with those having significant symptoms showing stronger association with nonadherence and more serious adverse events. This association was not explained by other psychiatric disorders.
Daily functioning and psychological symptoms improved in patients participating in a meditation training program, with benefits lasting up to one year. The program, known as MBSR, included mindfulness meditation training and group therapy, leading to reduced stress, anxiety, and depression.
A study published in the Journal of Clinical Oncology found PET scans to be more accurate than CT scans in detecting cervical cancer spread. The imaging method reveals metabolic differences between cancer cells and normal tissue, identifying abnormal lymph nodes.
A new study suggests that climate change, particularly drought, plays a key role in shaping plant communities. The research found that grasslands thrive in dry conditions, while trees and shrubs prefer wetter environments. This challenges the long-held assumption that CO2 levels are the primary driver of vegetation changes.
A recent international trial has shown that oxytocin is more effective than misoprostol in reducing maternal blood loss immediately after childbirth. The study found that 4% of women taking misoprostol experienced excessive bleeding compared to 3% on oxytocin.
A new study suggests that Asian Americans' higher anxiety scores on social phobia and anxiety tests may be a result of their culturally adaptive sensitivity in social situations. The researchers found that perceptions about norms were not related to the anxiety inventory scores among white Americans, but were related to those among Asi...
A study found that an oral immune-enhancing nutritional supplement improved preoperative host defence, reduced postoperative infections, and preserved renal function in elderly and high-risk patients undergoing elective coronary artery bypass. The supplement contained L-arginine, 3 polyunsaturated fatty acids, and yeast RNA.
Researchers have developed a technology to engineer proteins as widely adaptable bioelectronic sensors for detecting specific chemicals. The engineered proteins, when attached to electrodes, can produce an electric signal reflecting the chemical's identity and concentration.
Two Dartmouth researchers, Erland Schulson and Carl Renshaw, propose a theory that brittle materials like rocks and ice crack in the same manner. They identify a specific type of cracking mechanism, 'comb' cracks, which leads to collapse in both ice and rock.
Researchers have discovered a new antibody treatment that prevents severe lung injury in premature babies without using steroids, which can stunt brain cell growth. The treatment, anti-CINC-1, blocks the action of white blood cells and reduces inflammation, promoting normal lung development and function.
Researchers found that ultrasound-induced lung damage is dependent on beamwidth, pulse duration, and exposure duration. The air-blood barrier near the surface of the lung may be the principal target for ultrasound-induced lung damage.
QSulf1 enables embryonic cells to express muscle-specific proteins by modifying signaling co-factors. This discovery sheds light on the complex process of cell differentiation and has implications for regenerative medicine.
Torture is pervasive in Nepal, with severe physical, social, and psychosocial consequences for survivors. The Centre for Victims of Torture, Nepal, implements treatment programmes for victims, but international interest is needed to encourage change.
Researchers predict that 42% of all HIV cases will be drug-resistant by 2005, mainly due to the conversion of drug-sensitive cases during antiretroviral therapy. The study recommends four epidemic-control strategies to minimize prevalence and transmission of drug-resistant HIV.
Researchers have developed unique polymers that can stabilize liposomes, improving the solubility of hydrophobic drugs. These polymers also enable the creation of crystal-clear beauty products by altering the liposome solution.
Researchers successfully tested a corn-based activated carbon for removing mercury emissions from coal-fired power plants, achieving results comparable to commercial products. The technology demonstration marked the first time this approach was applied to high-sulfur Illinois coal flue gas.
A new study by Johns Hopkins Bloomberg School of Public Health finds that states with mandatory licensing and registration of handguns reduce the number of crime guns sold by in-state dealers. Cities with stricter gun laws have lower rates of crime guns sold outside the state, supporting the benefits of comprehensive handgun sales laws.
Researchers at UC Berkeley have developed a sensitive assay for detecting proteins associated with prostate cancer, which could lead to fast screening and molecular profiling for various diseases. The technique uses micromachined cantilevers that can detect levels of protein markers 20 times lower than the clinically relevant threshold.
A study of 16 'awareness' patients found that over half had PTSD, while control subjects showed no memory recall. Patients experienced intense emotions, helplessness, and dissociation after surgery.
Research suggests climate shifts, such as droughts and temperature changes, may be more important than carbon dioxide levels in determining plant community composition. The study analyzed sediment cores from Mexico and Guatemala, finding that trends in C3 versus C4 plants were correlated with shifts in rainfall rather than carbon dioxide.
