This sounds like the plot of a bugs bunny cartoon.
Smith College, an all-women’s college, was presented with petition signed by over 4,000 students last week in protests to the school’s current policy regarding transgender students and the denied admittance of an individual who was born assigned male but transitioned to female.
From this student petition, and from a widely-attended rally, the administrators at Smith College have announced that they will have a committee review their current policy when they convene in September.
I hope that this committee actually does review this policy and make changes where changes need to be made. Whatever the outcome is, as I have always said in the past, students’ voices will create change. Your voices matter.

been a while since my last post..
oh god, sounds like a great way too get sent to the ER i might just to this but with smoking weed :p
I’ve travelled back in time to 2002. Avril Lavigne is playing off in the distance.

I spent all day taking old computers apart. All of them had floppy drives and some even had Windows 98!
As life has evolved, its complexity has increased exponentially, just like Moore’s law. Now geneticists have extrapolated this trend backwards and found that by this measure, life is older than the Earth itself.
Here’s an interesting idea. Moore’s Law states that the number of transistors on an integrated circuit doubles every two years or so. That has produced an exponential increase in the number of transistors on microchips and continues to do so.
But if an observer today was to measure this rate of increase, it would be straightforward to extrapolate backwards and work out when the number of transistors on a chip was zero. In other words, the date when microchips were first developed in the 1960s.
A similar process works with scientific publications. Between 1990 and 1960, they doubled in number every 15 years or so. Extrapolating this backwards gives the origin of scientific publication as 1710, about the time of Isaac Newton.
Today, Alexei Sharov at the National Institute on Ageing in Baltimore and his mate Richard Gordon at the Gulf Specimen Marine Laboratory in Florida, have taken a similar to complexity and life.
These guys argue that it’s possible to measure the complexity of life and the rate at which it has increased from prokaryotes to eukaryotes to more complex creatures such as worms, fish and finally mammals. That produces a clear exponential increase identical to that behind Moore’s Law although in this case the doubling time is 376 million years rather than two years.
That raises an interesting question. What happens if you extrapolate backwards to the point of no complexity–the origin of life?
Sharov and Gordon say that the evidence by this measure is clear. “Linear regression of genetic complexity (on a log scale) extrapolated back to just one base pair suggests the time of the origin of life = 9.7 ± 2.5 billion years ago,” they say.
And since the Earth is only 4.5 billion years old, that raises a whole series of other questions. Not least of these is how and where did life begin.
Of course, there are many points to debate in this analysis. The nature of evolution is filled with subtleties that most biologists would agree we do not yet fully understand.
For example, is it reasonable to think that the complexity of life has increased at the same rate throughout Earth’s history? Perhaps the early steps in the origin of life created complexity much more quickly than evolution does now, which will allow the timescale to be squeezed into the lifespan of the Earth.
Sharov and Gorden reject this argument saying that it is suspiciously similar to arguments that squeeze the origin of life into the timespan outlined in the biblical Book of Genesis.
Let’s suppose for a minute that these guys are correct and ask about the implications of the idea. They say there is good evidence that bacterial spores can be rejuvenated after many millions of years, perhaps stored in ice.
They also point out that astronomers believe that the Sun formed from the remnants of an earlier star, so it would be no surprise that life from this period might be preserved in the gas, dust and ice clouds that remained. By this way of thinking, life on Earth is a continuation of a process that began many billions of years earlier around our star’s forerunner.
Sharov and Gordon say their interpretation also explains the Fermi paradox, which raises the question that if the universe is filled with intelligent life, why can’t we see evidence of it.
However, if life takes 10 billion years to evolve to the level of complexity associated with humans, then we may be among the first, if not the first, intelligent civilisation in our galaxy. And this is the reason why when we gaze into space, we do not yet see signs of other intelligent species.
There’s no question that this is a controversial idea that will ruffle more than a few feathers amongst evolutionary theorists.
But it is also provocative, interesting and exciting. All the more reason to debate it in detail.

We’ve all been there: You’re at work deeply immersed in a project when suddenly you start thinking about your weekend plans. It happens because behind the scenes, parts of your brain are battling for control.
