New study shows that when placed in microgravity, 80 to 90 percent of the cells in four different cancer types (ovarian, breast, nose and lung) were disabled by gravitational forces alone. This could lead to new treatments of cancer using similar conditions to microgravity.

Data-driven analyses of motor impairments in animal models of neurological disorders
This study demonstrates that a state-of-the-art neural network can provide automated scoring of motor deficits with an accuracy equivalent to that of human experts and has the potential teach us to develop more-sensitive behavioral tests.
Domesticated dogs have the the ability to spontaneously recognise and normalise both the same phonemes across different speakers, as well as cues to the identity of a word across speech utterances from unfamiliar human speakers, a trait previously thought to be unique to humans.

Early humans domesticated themselves, new genetic evidence suggests, after they split from their extinct relatives, Neanderthals and Denisovans, approximately 600,000 years ago. Many of the same genes analyzed in the new study have also been under selection in other domesticated animals.

A new oral contraceptive that only has to be taken once a month, could reduce unintended pregnancies that result from forgetting to take a daily dose. This kind of monthly contraceptive could have a significant impact on the health of women and their families, especially in the developing world.

太阳“寿终正寝”之后人类生存的地球上会怎样?
宇宙间万事万物,都是有其寿命的,包括我们人类赖以生存的太阳。 根据科学家的计算,太阳最多大约还有50至60亿年的寿命。 而科学家最近所发现的一个天文现象,为他们提供了几十亿年后当我们的太阳“寿终正寝”后未来的一瞥。 白矮星 天文学家观察到一颗巨大的行星围绕一颗白矮星(white dwarf)在运行。 白矮星通常是恒星在耗尽了核燃料,它的核心就会坍缩成为致密的白矮星。白矮星是低质量恒星演化路线的终点。 恒星在经历红巨星阶段的末期,它的中心会因温度、压力不足以使碳氧元素进行核聚变,从而产生一个致密天体。大部…
