The research also showed that Bonds' stories were more likely to focus on his using steroids for a competitive edge, rather than rehabilitation from injury.
A rare new plant species, Stachys caroliniana, has been discovered in two locations near Charleston, S.C., with the discovery shedding light on its unique characteristics. The species was found to be different from its closest relatives, which are commonly known as hedge-nettles or woundworts.
Climate change may be causing fiddler crabs to move further north in the US East Coast, with one scientist discovering a crab nearly 50 miles north of its usual range. This warming trend could lead to changes in ecosystems as new species are introduced.
A GPS-collar study found that leopards stay surprisingly close to homes and can thrive in human-dominated areas, depending on resources. The study's findings suggest that leopards are not always 'stray' or 'conflict' animals but residents, requiring policy makers to rethink conservation strategies.
Two new treatments for liver diseases are being explored. A probiotic, VSL#3, has been shown to improve liver function and reduce the risk of hospitalization in patients with cirrhosis. Meanwhile, a fatty acid conjugate called Aramchol has been found to significantly reduce liver fat content in patients with nonalcoholic fatty liver di...
The investigational drug patiromer decreased high potassium levels and maintained normal levels in patients with chronic kidney disease. Elevated potassium increases the risk of death in high-risk patients and limits the use of certain drugs used to control hypertension and cardiovascular disease.
A new study from Oregon State University found that an intervention using music and games improves self-regulation skills in preschoolers, preparing them for kindergarten. The program had a positive effect on math achievement among English language learners.
A new tool provides real-time ocean chemistry data along the West Coast, helping scientists understand changes in water chemistry and aid the shellfish industry. The IOOS Pacific Region Oean Acidification Data Portal offers valuable insights for adapting to ocean acidification.
Clemson University researchers are developing new instruments to measure ultra-high-resolution strain movements in underground CO2 storage sites. The goal is to improve the ability to monitor and safeguard geologic carbon storage, making it cheaper and safer.
Researchers have identified a natural resistance gene in white spruce trees that makes them resistant to the devastating spruce budworm. The gene, betaglucosidase-1, produces compounds toxic to the caterpillar, potentially allowing for replanting of forests affected by the pest.
A University of Cincinnati doctoral student presents research on the legal issues posed by transgendered inmates, including Eighth Amendment protections and varying policies. The study aims to create a manual for prison institutions to guide treatment of this population.
Researchers at the University of Texas at Arlington are exploring ways to create more human-like interactions between humans and robots. Julienne Greer, a theatre arts lecturer, is using her expertise in performance technique method acting to inform the design of robots like Pepper, which can understand and respond to human emotions.
New research examines the effects of powered prosthetic leg errors on users, revealing some mistakes are insignificant, while others can cause noticeable instability. The team aims to improve decoding accuracy and minimize mechanical work changes to create more reliable prostheses.
A new study reveals how the immune system recognizes enemies on a molecular level and how this process can go wrong, leading to autoimmune diseases. The research also offers insights into training the immune system for vaccine development.
A study found that people tend to accept dates from unattractive partners when faced with a potential date, rather than rejecting them due to concerns about hurting the other person's feelings. This bias was observed even when participants knew they would not meet in person, suggesting that social consideration can influence dating dec...
A new simulation demonstrates that hummingbirds generate lift and thrust using unsteady airflow mechanisms, creating invisible vortices of air. This unique approach sets them apart from larger birds and is more closely aligned with insect flight.
A recent study by Michigan State University found that employee motivation increases when workers and their supervisors share similar views on the quality of their relationship, even if the relationship is poor. This discovery suggests that being honest about one's feelings can lead to better work engagement and performance.
Vermicompost leachate enhances tomato seedling growth in temperature and water-stress conditions. Regular supply of VCL improves morphological characters, including leaf area and shoot/root biomass.
Researchers at UCSF have identified patterns of genetic activity that can be used to diagnose endometriosis and its severity, offering a less invasive alternative to surgery. The test uses machine learning to analyze gene expression patterns in uterine lining cells.
A clinical trial found that patients who received more CD34+ bone marrow cells experienced significant benefits, with improved ejection fraction and lower rates of major adverse cardiac events. The study, which enrolled 161 patients, showed a dose-dependent trend in the effects of cell therapy on heart function.
Researchers mapped p53 binding sites in human cancer and normal cells, finding the protein binds selectively to repeat sequences in cancer cells. This suggests p53's role in maintaining genomic stability and tumor suppression is context-dependent.
A study by Columbia University's Mailman School of Public Health estimates that obesity-attributable absenteeism among US workers costs the nation more than $8 billion annually, with state-level costs ranging from $14.4 million in Wisconsin to $907 million in California.
Researchers have found four novel loci associated with eosinophilic esophagitis, a severe food allergy. The study suggests that genetic factors play key roles in the disease and may offer attractive targets for therapy. Understanding these biological networks could lead to tailored approaches for treatment.
Researchers have made breakthroughs in personalized vaccine technology for all types of cancer, using genes expressed in tumors to create tailored vaccines. The approach has shown promise in improving biological responses and disease control.
Researchers found that using clear polyethylene mulch on well-irrigated beds under high tunnel glazing can achieve significant disinfestation of soil pathogens and pests within less than one week. This method requires a combination of daily solar radiation, high temperatures, and low relative humidity.
