Drinking coffee might make you feel better about people in a conversation. Having a cup of coffee before a discussion could not only help you focus more, but it could also make you feel better about the people you're conversing with, according to a study in the Journal of Psychopharmacology. For the study, researchers divided up 134 college students into groups and had them discuss the Occupy Wall Street movement for 15 minutes. The researchers found that the participants who drank caffeinated coffee before their discussion were better at focusing and felt better about themselves and the other participants, when compared with those than those who did not have a caffeine jolt.
Time to bust out the SPF 100? Most people don't put on enough sunscreen, so it might be better for them to wear SPF 100 rather than SPF 50, according to a new study in the Journal of the American Academy of Dermatology. For the study, researchers gave 199 men and women two tubes of sunscreen—one labeled "left" and the other labeled "right"—and asked them to apply the cream to specific parts of their face and neck. The participants then spent their day at a ski resort on a sunny day. The next day, the researchers rated the severity of their sunburns on a five-point scale and found that, on average, the score was more than twice as high for those who used SPF 50 than for those who used SPF 100. Darrell Rigel, senior author on the study and a professor of dermatology at New York University, explained that while laboratory results show little difference between SPF 100 and SPF 50, " the higher SPFs are much more forgiving [in the real world], and since people are under-applying sunscreen, they're much more likely to protect."

It really doesn't take that long to bike to work. Most people overestimate how long it will take to bike or walk to work, according to a new study. Researchers asked students, staff, and facility at Penn State University how long they thought it would take them to walk or bike to work. When the researchers compared the guesses to Google Maps calculations, roughly 90% of participants overestimated by at least 10 minutes. The researchers noted people with parking permits were especially likely to overestimate the biking/walking commuting time.
How big exactly? A new paper in Nature finds that far off in space, 14 hot galaxies are on track to collide and create what the Los Angeles Times' Deborah Netburn describes as "the most massive structure known in the cosmos." It'll take light 12.4 billion years to get to the galaxy, meaning the cluster was created 1.4 billion years after the universe was born—and researchers are confused by that detail. Scott Chapman, a physicist at Dalhousie University in Halifax, Canada, who worked on the study, said, "We don't know how it is possible." He added, "We don't know how you get those 14 galaxies right down the center of the protocluster at such an early time."
