Researchers using Aura's nearly up-to-the-hour data track important pollutants like ozone and nitrogen oxide. The satellite provides better predictions of future climate change by monitoring ice in clouds, which affects solar energy reflection and radiation trapping.
A large study found an increased risk of second cancers in various sites, including connective tissue and myeloid leukemia, after breast cancer diagnosis. Treatment for breast cancer and shared genetic or environmental factors are thought to contribute to this risk.
A Berkeley lab scientist has found a spike in micro-earthquakes followed by relative calm months before a large quake occurred. This discovery may help predict destructive earthquakes within a shorter time frame than current statistical tools.
A CU-Boulder study found that moderate exercise extended the life expectancy of lab rats carrying a genetic blueprint for heart failure by at least 10 percent to 15 percent. This suggests low-intensity exercise may have benefits in early stages of congestive heart failure.
Research suggests adult children's ability to predict their parents' wishes is influenced by family dynamics and interaction style. Children who perceive closer relationships are often better at guessing parental preferences, while autonomy and personal growth are poorly predicted decisions.
Researchers found that plants respond differently to bacteria that efficiently produce nitrogen, with root nodules growing bigger in response to good sharers. This complex relationship suggests that agricultural practices could disrupt these interactions and create plants with reduced ability to choose among root bacteria.
Scientists at Max Planck Institute and University of Cologne isolate mutant Arabidopsis thaliana with single sperm cell, allowing it to germinate and fertilize. The researchers found that a positive signal from the egg cell's fertilization triggers endosperm proliferation.
The Bornean elephant has been confirmed as a separate sub-species, with an estimated 1,100-1,500 individuals remaining in the wild. The Cardiff University study will provide essential conservation information and training for Malaysian organizations on wildlife monitoring techniques.
Researchers at Washington University in St. Louis have developed a new technique to image brain deformation after impact, using magnetic resonance imaging (MRI). The study shows that the brain tries to pull away from attachments, leading to significant deformation of the front of the brain.
Long-term Phase 3 data from ACT 1 and ACT 2 trials demonstrate REMICADE's efficacy in achieving clinical response, clinical remission, and mucosal healing in UC patients. Approximately two-thirds of patients treated with REMICADE achieved the primary endpoint of clinical response.
Researchers have discovered a new muscle-building agent that increases muscle size by 60% in mice after just two weekly injections. The agent targets the myostatin protein and has shown promising results in mice with muscular dystrophy, suggesting potential for treating muscle-wasting diseases.
Researchers at Arizona State University have developed a technology that can directly identify single nucleotide polymorphisms (SNPs) in DNA molecules using electrical conductivity. The technique involves measuring the electrical conductance of a single DNA molecule, which can reveal sequence information and detect mutations.
The World Health Organization (WHO) emphasizes the importance of preparing health ministries for progressive liberalization of trade in health services. The WHO should continue to provide guidance on international standards and advice on trade rules from a public-health perspective.
A pilot study on an online information system for multiple sclerosis patients will be conducted using the software developed by Cerner Corp., enabling direct access to medical records and prescription drugs, as well as private e-mail correspondence with physicians.
Researchers have found that a specific immunization strategy targeting Abeta42 or Abeta40 can prevent amyloid deposition in mice, suggesting an effective approach for preventing Alzheimer's disease. However, this method may not be effective once existing deposits are established.
The Lancet is hosting a conference on child survival progress, focusing on reducing neonatal deaths by two-thirds by 2015. The event aims to provide opportunities for politicians and health-care workers to invest in proven interventions that can save one newborn life for every $2100 invested.
The Huygens probe has revealed that Titan's surface is a barren, 'river' landscape where water ice congeals like stone. Methane plays a similar role to water on Earth, existing in solid, liquid, and gas states. The dense atmosphere has conditions similar to those early in our solar system.
A team of scientists at Duke University used computer-chemistry techniques to study the docking orientation required for a Cdc25B phosphatase enzyme to activate a cyclin-dependent kinase protein complex. The researchers discovered that specific hot spots on the molecules' surfaces must align precisely for the brief docking to accomplis...
A review and meta-analysis of 127 trials found ACE inhibitors and ARBs no better than other drugs in preventing diabetic kidney disease. Treatment decisions for hypertension in renal disease should be based on blood-pressure-lowering effect, comparative tolerability, and cost.
Researchers discover that preventing amyloid deposition may be easier than curing established Alzheimer's disease through an immunization strategy targeting Abeta42. Additionally, a study finds that pre-treatment of patient T cells with IL-10 and vitamin D3 can overcome glucocorticoid resistance in asthma patients.
Researchers found that vitamin D3 supplementation can increase the responsiveness of T-cells from patients with severe asthma to steroids. The study suggests that this therapy could lead to new ways to treat people who don't respond to steroid treatment, reducing the need for heavy medication.
A recent study found that exercise is related to gastrointestinal symptoms and protective against them, contradicting previous assumptions. Participants who engaged in physical activity experienced lower levels of GI problems, including abdominal pain, irritable bowel syndrome, diarrhea, and bloating.
Researchers have made a breakthrough in unravelling the causes of sudden cardiac death in young people, linking it to genetic mutations in calcium release channels. These mutations destroy the channels' ability to work properly after stress or exercise, leading to fatal heart rhythms.
Researchers estimated that 150 blood group compatible donors, 100 O donors, or ten highly selected donors could provide maximum benefit for HLA matching. The study aims to establish a hESC bank with sufficient HLA diversity for the UK population.
A new study by BCIRG shows that Herceptin paired with chemotherapy significantly improves disease-free survival in early breast cancer patients, while eliminating cardiac toxicity. The treatment also reduces the risk of relapse by 51% and is an alternative to standard therapy for patients at risk of heart damage.
A recent study found that performing monkeys in Asia carry various simian viruses, including simian foamy virus and simian retrovirus. These viruses pose a potential risk of transmission to humans, particularly in settings where people have close contact with non-human primates.
A pilot study found that pairing low-dose chemotherapy with the anti-VEGF antibody bevacizumab delayed breast cancer progression by an average of 5.5 months compared to low-dose chemotherapy alone. The combination therapy showed better results, with 29% partial responses and 41% stable disease.
Land use changes in the Amazon region could exacerbate global warming due to deforestation, while agriculture in midlatitudes can counteract warming by up to 50%. The study utilized a global climate model to examine two scenarios from the Intergovernmental Panel on Climate Change and found contrasting results
The University of Pittsburgh has established an Immune Modeling Center to study immune responses to infectious diseases using mathematical modeling. The center will focus on understanding innate and adaptive immune responses to influenza A virus, Mycobacterium tuberculosis, and Francisella tularensis.
