Next time you eat a blueberry (or chocolate chip) muffin consider what happened to the blueberries in the batter as it was baked. The blueberries started off all squished together, but as the muffin expanded they started to move away from each other. If you could sit on one blueberry you would see all the others moving away from you, but the same would be true for any blueberry you chose. In this sense galaxies are a lot like blueberries.

Since the Big Bang, the universe has been expanding. The strange fact is that there is no single place from which the universe is expanding, but rather all galaxies are (on average) moving away from all the others. From our perspective in the Milky Way galaxy, it seems as though most galaxies are moving away from us – as if we are the centre of our muffin-like universe. But it would look exactly the same from any other galaxy – everything is moving away from everything else.

To make matters even more confusing, new observations suggest that the rate of this expansion in the universe may be different depending on how far away you look back in time. This new data, published in the Astrophysical Journal, indicates that it may time to revise our understanding of the cosmos.

At a pier in San Diego, researchers on Wednesday recorded the warmest sea surface temperature since record-keeping began there in 1916.

Every day, researchers from the Scripps Institution of Oceanography at the University of California San Diego collect data — by hand — from the Ellen Browning Scripps Memorial Pier.

Wednesday’s 78.6 degrees Fahrenheit at the pier surpassed a previous record of 78.4 degrees in 1931, researchers said in a statement on Thursday.

A BASIC income (BI) is defined as a modest, regular payment to every legal resident in the community, paid unconditionally as a right, regardless of income, employment or relationship status.

Contrary to conventional wisdom, the case for BI does not rest on the assumption that robots and artificial intelligence will cause mass unemployment or that it would be a more efficient way of relieving poverty than present welfare systems (although it would). The main arguments are ethical and relate to social justice, individual freedom and the need for basic security.

Often only a few years separate the tinfoil hats from the millionaires to be. I was writing the piece on the Youbionic arm and thinking of how we will use 3D printing to augment human beings. Clearly augmenting the human body with mechatronics would be a good idea. The flesh is weak but stepper motors are strong! Oh how we will eeck, ooow, brrrr whine in our old stepper augmented age. Machines could very well fill the gaps once our bodies start failing us. But, will old people homes really be filled with Borg grandmas?

Will your grandad get that night vision upgrade he’s always wanted so he can deer hunt whenever he damn pleases? Would it be a good idea if I on a whim replaced my tennis elbow with a tennis racket? We never get the future right and most of our visions of mechatronic augmentations of humans are either a bit Johhny Cab or they’re ruined by that tiara Geordi was wearing across his face in Star Trek. I know he can’t see it, but someone should have told him really.

This is part of our ongoing series of articles that discuss the Hallmarks of Aging. Published in 2013, the paper divides aging into distinct categories (“hallmarks”) of damage to explain how the aging process works and how it causes age-related diseases. Today, we will be looking at the hallmark of cellular senescence.

What are senescent cells?

As you age, increasing numbers of your cells enter into a state known as senescence. Senescent cells do not divide or support the tissues of which they are part; instead, they emit a range of potentially harmful chemical signals that encourage nearby healthy cells to enter the same senescent state. Their presence causes many problems: they reduce tissue repair, increase chronic inflammation, and can even eventually raise the risk of cancer and other age-related diseases.
