Could Velociraptors have attacked from above?

A recent paper by Phil Manning of the University of Manchester, UK, suggests that Velociraptors may have used their fearsome claws to climb trees and attack prey by leaping down on them. This theory is based on further biomechanical considerations based on his earlier assertion that the claws "could puncture skin and help the dinosaur cling to wounded prey but... [not] rip the skin open." Manning goes on to mention that the Microraptor is now known to have used feathery forelimbs to glide down from trees. These suggestions are further emphasized by the recent findings of Ken Dial at the University of Montana. With slow motion video footage, Dial has shown that ground birds with flight abilities will use their claws to aid their wings in the ascension of vertical surfaces.

"'Liposuction Leftovers' Easily Converted To Induced Pluripotent Stem Cells"

"Globs of human fat removed during liposuction conceal versatile cells that are more quickly and easily coaxed to become induced pluripotent stem cells, or iPS cells, than are the skin cells most often used by researchers, according to a new study from Stanford's School of Medicine."

"Super Sperm - An Evolutionary Reason For Infertility?"

"'The rate of human infertility is higher than we should expect it to be,' says Dr. Hasson. 'By now, evolution should have improved our reproductive success rate. Something else is going on.' Combining empirical evidence with a mathematical model developed in cooperation with Prof. Lewi Stone of the department's Biomathematics Unit, the researchers suggest that the bodies of men and women have become reproductive antagonists, not reproductive partners. The conclusions of this research were published recently in the journal Biological Reviews."

"Truth or Lies"

For some, it may require just as much effort to tell the truth as it does to lie.

First Evidence Of Virus In Malignant Prostate Cells: XMRV Retrovirus Linked To More Aggressive Tumors

"If further investigation proves the virus, XMRV (Xenotropic murine leukemia virus-related virus), causes prostate cancer in people, it would open opportunities for developing diagnostic tests, vaccines, and therapies for treating the cancer, according to the study published Sept. 7 online in the Proceedings of the National Academy of Sciences."

Being bad is good!

Apparently, there is evidence that many things typically labeled as "bad" actually provide some benefit.

"One of the oldest canards in the creationists' book is the claim that evolution must be false because it violates the second law of thermodynamics...

..., or the principle that, as they put it, everything must go from order to disorder."

[via NewScientist by way of NewScientist]

The idea is defended with some astute mathematical comparisons, culminating in:

"To spell it out, there's about a trillion times more entropy flux available than is required for evolution. The degree by which earth's entropy is reduced by the action of evolutionary processes is miniscule relative to the amount that the entropy of the cosmic microwave background is increased."

In fact, a recent modeling effort intended to illustrate the possibilities of life spontaneously erupting from primordial soup determined that "[w]ithout the ability of tRNAs to discriminate between various amino acids, such a random system might not be able to self-assemble into a highly organized code capable of supporting life." "They found that the properties of the molecules set the concentrations at which the molecules needed to exist for a coded regime to emerge."
