A new study investigates the effects of light intensity on pecan leaves throughout the growing season. The research found that shade leaves are less effective in assimilating CO2 than sun leaves, but maintain late-season photosynthetic capacity. This discovery may help commercial growers develop new canopy and crop management practices.
Research shows women exiting welfare have similar marriage rates to those without welfare. The temporary disincentive to marry while receiving benefits may be reduced by allowing spouses' earnings not affect eligibility. Researchers observed over 3,000 women and debunked long-standing debates on the impact of poverty on family values.
Researchers find that removing fruit from 'Pixie' mandarin trees reduces floral intensity of return bloom by inhibiting budbreak. Growers can investigate degrees of fruit thinning or pruning to mitigate alternate bearing, which is exacerbated by holding fruit on the tree to extend commercial harvest period.
A recent study found that a person's facial width-to-height ratio can be used to predict their tendency towards aggression. Volunteers rated the aggressiveness of male faces and found high correlation between the rating and the face's WHR, suggesting that subtle differences in face shape may affect personality judgments.
A study published in the World Journal of Gastroenterology investigated whether children can tolerate surgery without fasting. The results showed that children can handle the stress of surgery when fed up to 2 hours before surgery, indicating no significant difference between short and long periods of fasting.
A 33-year-old woman accidentally swallowed a 15 cm long spoon while attempting to remove a fish bone from her pharynx.

Raptorex displays all the hallmarks of Tyrannosaurus rex, including a large head and tiny arms, at about 100th the size that would eventually become T. rex. This suggests that tyrannosaur design evolved at a small body size, with larger animals developing later.
A new species of tyrannosauroid dinosaur, Raptorex kriegsteini, has been discovered in China that predates the Tyrannosaurus rex by tens of millions of years. The fossil, which is only three meters long, exhibits the same physical traits as T. rex, including an oversized skull and powerful jaws.
A study published in the World Journal of Gastroenterology evaluated 76 cases of living donor liver transplantation and found that the Chengdu formula is reliable. The other formulas, such as Fan and Heinemann, underestimated liver volume, while Urata and Lee overestimated it.

A study published in Psychological Science found that carrying a heavy clipboard increased volunteers' judgment of the value of foreign currencies and the importance of social justice issues. The researchers propose that this effect may be linked to embodied cognition, where bodily experiences shape mental processes.
Researchers at the University of Haifa have developed a handwriting-based tool that measures physical properties of handwriting to detect deception. The tool shows promise in replacing verbal-based methods such as polygraphs, providing greater accuracy and ease for law enforcement.
A new study finds that abstainers are more likely to report symptoms of depression than moderate drinkers, with those labeling themselves as 'abstainers' at the highest risk. Other factors like age and social isolation may contribute to this increased risk.
Researchers found that acute transient hepatocellular injury occurs in patients with cholelithiasis and cholecystitis without evidence of CBD stones, resolving within weeks after surgery. Markers of liver damage are more severe in those with CBD stones or histologically less severe inflammation.
A rare case of duodenal obstruction after successful embolization for duodenal diverticular hemorrhage was reported. The study highlights the importance of thorough observation of resolving hematomas and conservative treatment before surgery to relieve duodenal fibrotic encasement.

A recent study published in Psychological Science found that bilinguals cannot completely 'turn off' a language, as knowledge of a second language affects native-language reading. Bilingual students read sentences with control words and cognates, showing shorter fixation times on cognates than controls.
Researchers at Delft University of Technology discovered that bacteria can retain motility in surprisingly narrow channels, growing and dividing instead of swimming. This new phenotype may be more common than thought, with implications for membrane filters and medical applications.
The partnership aims to increase the value of Science research by providing interactive video demonstrations of experimental techniques. The first video in the program showcases an innovative method for visualizing immune control in viral infections.
Patients with primary sclerosing cholangitis (PSC) have significantly larger fasting and postprandial gallbladder volumes compared to healthy controls. However, there is no correlation between gallbladder size or emptying and the occurrence of abdominal pain in PSC patients.
Researchers found that perianal disease, current smoking, prior steroid use and early azathioprine or biological therapy are predictors of disease behavior change in CD patients. These findings may aid clinicians in choosing the treatment strategy for their patients.
A recent study published in Environmental Science & Technology found that bioethanol production requires up to 861 billion gallons of water, with some regions consuming as much as 2,100 gallons per gallon of ethanol produced. This highlights the need for regional-specific considerations when implementing biofuel mandates.
Researchers have gained in-depth knowledge of pyruvate carboxylase's structure, a metabolic enzyme linked to genetic diseases like lactic acidaemia and hypoglycaemia. The study also sheds light on its potential role in obesity and diabetes treatments.
Research shows that individuals tend to overestimate their ability to control impulses, leading to a greater likelihood of indulging in impulsive or addictive behavior. The study found that people in a 'cold state' underestimate the influence of impulsive states on their behavior.
Researchers discovered how resveratrol controls inflammation by inhibiting two molecules that trigger inflammatory responses. The findings suggest resveratrol may be used to treat inflammatory diseases and lead to new resveratrol-based drugs.
Researchers discover that mitochondrial diseases increase susceptibility to bacterial infection, particularly with pneumonia-causing bacteria like Legionella. The stress-signal associated with metabolic abnormalities encourages the growth and reproduction of these bacteria.
Researchers found that loyalists who were most devoted to their school were also the most cooperative and helpful when confronted with injustice. However, this loyalty was short-term and may fade if the group continues to exhibit unfairness.
Research by Nansook Park and Christopher Peterson highlights the importance of experiencing positive emotions, having close interpersonal relationships, and finding meaning in life. The authors suggest that psychology has made progress in understanding human problems but still lacks a formula for achieving a good life.
A new study found that inhaling linalool, a key ingredient in aromatherapy, can alter gene activity and blood chemistry to reduce stress levels. The study also showed that linalool returned stress-elevated levels of immune cells to near-normal levels.
