Researchers turn one form of adult mouse cell directly into another from PhysOrg.com
(PhysOrg.com) -- In a feat of biological prestidigitation likely to turn the field of regenerative medicine on its head, Harvard Stem Cell Institute (HSCI) co-director Doug Melton and post doctoral fellow Qiao "Joe" Zhou report having achieved what has long been a dream and ultimate goal of developmental biologists – directly turning one type of fully formed adult cell into another type of adult cell.

Aussies crack cancer secret (from the Daily Telegraph):
AUSTRALIAN scientists are hoping to cure leukaemia, asthma and rheumatoid arthritis after their breakthrough discovery of how to stop killer blood cells growing.
The team has unlocked the secrets behind the protein which controls the way the blood cancer cells spread when it is damaged - and have found a way to stop its deadly process.
So much for firewalls and other site-specific security measures: Hackers hacked at infamous DefCon gathering from PhysOrg.com
In the end, it was hackers at DefCon that got hacked. After three days of software cracking duels and hacking seminars, self-described computer ninjas at the infamous gathering in Las Vegas found out Sunday that their online activities were hijacked without them catching on.

In scientific first, researchers correct decline in organ function associated with old age from PhysOrg.com
As people age, their cells become less efficient at getting rid of damaged protein — resulting in a buildup of toxic material that is especially pronounced in Alzheimer's, Parkinson's disease, and other neurodegenerative disorders.

From 3-D to 6-D: Researchers developing super-realistic image system from PhysOrg.com
(PhysOrg.com) -- By producing "6-D" images, an MIT professor and colleagues are creating unusually realistic pictures that not only have a full three-dimensional appearance, but also respond to their environment, producing natural shadows and highlights depending on the direction and intensity of the illumination around them.

Universally speaking, Earthlings share a nice neighborhood from PhysOrg.com
We don't have spacecraft to take us outside our solar system--not yet, at least. Still, astronomers thought they had a pretty good understanding of how our solar system formed and in turn, how others formed. In the last dozen years, nearly 300 exoplanets have been discovered. Are the solar systems in which they reside indeed like our own?

Rochester physicist's quantum-'uncollapse' hypothesis verified from PhysOrg.com
In 2006, Andrew Jordan, professor of physics and astronomy at the University of Rochester, together with Alexander Korotkov at the University of California, Riverside, spelled out how to exploit a quantum quirk to accomplish a feat long thought impossible, and this week a research team at the University of California at Santa Barbara has tested the theory, proving it correct.
