“SIXTH SENSE” IS REAL

Scientists have known about a gene called PIEZO2 for 100 years, but a new study shows how it controls our '6th sense' of spatial awareness. NIH scientists discovered this by testing two girls who lack the gene, and neither of the girls can walk or reach for something when blindfolded. (dailymail.co.uk)基因決定“第六感”科學家們最近發現，人體的PIEZ02基因關聯著人的“第六感”，控制人的觸覺和本體感覺，也就是“第六感”。主要研究對象是兩名沒有PIEZ02 基因的女孩，她們因此出現行動和平衡障礙，還有部分觸覺缺失。

WHEN YOU STAY IN TOUCH WITH YOUR EX

Lindsay Rodriguez and her colleagues surveyed young adults in romantic relationships and came up with the conclusion that greater longing for an ex is associated with decreases in satisfaction with your current partner over time, and decreases in satisfaction over time are associated with increases in longing for an ex. (Psychology Today)分手后與前任保持聯系對健康不利不少人信奉“分手亦是朋友”，但美國一項研究顯示，和前任保持聯系不是什么好事。南佛羅里達大學心理學家琳賽· 羅德里格斯與同事一起調查了429 名成年人。超過四成的人承認仍與上一任戀人保持聯系。研究人員警告說，與前任藕斷絲連對自己的心理健康不利，雖然聯系后會暫時獲得安全感，但會讓自己更難走出分手的陰影。

“FIVE-SECOND RULE” FOR FOOD ON FLOOR IS UNTRUE

Rutgers University researchers have disproven the widely accepted notion that it's okay to scoop up food and eat it within a “safe” five-second window. Researchers found that moisture, type of surface and contact time all contribute to cross-contamination. In some instances, the transfer begins in less than one second.（Rutgers）“5 秒定律”系以訛傳訛？食物掉地上1 秒被污染民間流傳的“5 秒定律”認為，若食物不慎掉在地上，因細菌轉移至食物上需時，只要5 秒內取起仍可安全食用。不過，研究稱，該定律是以訛傳訛。美國新澤西州羅格斯大學研究顯示，細菌不足1 秒便可污染掉在地上的食物。

BABIES WITH LARGER HEADS HAVE BETTER COGNITIVE ABILITY

Scientists at UK Biobank studied 100,000 Britons to see if there is a link between their genes and their achievements. They found that those with larger heads were “significantly”more likely to get a degree, as well as score higher on verbal-numerical reasoning tests. (Huffington Post)頭大的寶寶更聰明？腦容量越大智商越高科學家發現，嬰兒出生時頭的大小與今后的成就有密切關系，頭圍越大，腦容量越大，智商就越高。英國生物醫學庫對10 萬名英國人進行了長期的研究，以找出人的基因、身體和精神健康狀況與人生道路之間的關系。
