A new study led by Ohio State University's Douglas Downey found that school achievement drops with increasing family size, but not among Mormon children. Despite having more siblings, Mormons devote more resources to their children, enabling them to achieve academically.
A recent study found that women who participated in a short sexual assault education program were just as likely to experience sexual assault as those who didn't participate. The research suggests that these programs may only help women learn more about sexual assault, without reducing the risk of assault.
A study by Ohio State University researchers reveals that low-prejudice people are more critical of weak arguments made by minority group members, while high-prejudice individuals ignore such statements. Low-prejudice individuals notice flaws in arguments from minority groups and are motivated to ensure their responses are not prejudiced.
Scientists found that genetically-engineered oilseed rape produces hybrid, transgenic weeds resistant to herbicides, which reproduce as prolifically as unaltered weeds. These weeds may carry beneficial traits from the crop parent and still exhibit weed-like characteristics.
Researchers at Ohio State University have developed a new process to create near-net-shaped ceramic parts without shrinking or changing shape. The method uses a mixture of ceramic and metal powders, which oxidize to form ceramics with desired properties.
Researchers at Ohio State University found that intervention and participation techniques led to successful decisions 90% of the time, but were used in only 13% and 16% of cases respectively. Meanwhile, managers relied on less effective tactics like issuing edicts, which was used in nearly 40% of cases.
A new study published in the Astrophysical Journal Letters finds that a review of thousands of nearby stars failed to show any rogue stars capable of altering comet orbits and sending them towards Earth. The researchers used the HIPPARCOS catalogue, which measures the location and motion of over 120,000 stars, and found no evidence of a

The brain's biochemical signals play a major role in food choices, particularly where fat, carbohydrates, and total calories are concerned.
Researchers found that aspirin targets patients with the altered gene PlA2 polymorphism, making them 10 times more sensitive to its effect. This discovery could help determine which people benefit most from daily aspirin doses and when other non-aspirin drugs are needed.

The square-shaped wrist and abductor pollicis brevis (thenar) weakness tests are recommended as part of the examination for CTS, which is often caused by repetitive motion like typing.
A new national study found that young men who switch jobs early in their careers don't suffer from lower wages, and may even earn more than those who stay in the same job. In contrast, women's wage gains are less clear, with some evidence suggesting they may face a 2% penalty for early job stability.
Researchers at Ohio State University have developed a new psychoeducation program that helps families deal with children diagnosed with depression, dysthymic disorder, and bipolar disorder. The program has shown early signs of improvement in parents' understanding of their child's mood disorder and family interactions.

The NEC-BSC program traces the path of electromagnetic waves and allows for the design of lighter materials and improved radar performance.
Researchers at Ohio State University have developed a fast new method to analyze part designs and locate potential defects that may form in die-cast metal parts. The binary voxel model uses geometry to simulate die casting, producing an image with color-coded areas of concern. This method can identify weak spots in seconds, unlike more...
A new study at Ohio State University reveals that three out of four mothers feel their partner's opinion greatly influences their decision to breast-feed. Fathers' negative attitudes about breast-feeding often stem from misconceptions or feelings of being left out, but education can change these attitudes.
A new study by Ohio State University researchers found a significant surge in trampoline-related injuries among children, with almost 250,000 treated between 1990 and 1995. The annual number of injuries grew from 29,600 to 58,400 per year during this period, with younger children most often suffering fractures or dislocations.
The study, led by Ming-Daw Tsai, used nuclear magnetic resonance spectroscopy to determine the 3D structure of the p16 protein. The researchers aim to develop a drug that mimics p16 to treat cancer, which is expected to target more than 70 different types of cancer.
A study of 514 Ohio residents found that 54% would support assisted suicide if doctors took an active role, such as giving a lethal injection. This result contradicts the leaders of the assisted suicide movement who advocate for less physician involvement and more patient control.
A study by Ohio State University researchers found that high-testosterone males were more likely to fertilize females other than their mates, resulting in fewer offspring with their own mates. Conversely, these males produced more offspring with the mates of their neighbors.
A study of 224 middle-aged and older adults found that avoiding pessimism had a greater impact on well-being, whereas optimistic thinking did not have as large an impact. The study also showed that caregivers were more pessimistic and less optimistic than non-caregivers.
A study of 456 nurses found that satisfaction accelerated as pay levels increased, suggesting that employers can't assume they know how pay raises will affect satisfaction. The researchers identified several reasons for this phenomenon, including long-term budget constraints and inadequate performance appraisal systems.
