Not
long after a partially paralyzed man in Switzerland used his mind to
remotely control a small robot, a Massachusetts woman paralyzed for 15
years used only her thoughts to direct a robotic arm to pick up a bottle
of coffee and bring it to her lips But will the experimental
brain-controlled technology ever help paralyzed people in everyday life?

A team from Tel Aviv University and the Hebrew University of Jerusalem has married biology and engineering to produce a biosensor device called the Dip Chip, which detects toxicity quickly and accurately, generating low false positive and false negative readings. The technology contains microbes designed to exhibit a biological reaction to toxic chemicals, emulating the biological responses of humans or animals.

A
research team at Rutgers University has been able to take a new
pharmacological approach to activate the immune cells to prevent cancer
growth through stimulation of the opiate receptors found on immune
cells.

The superbugs have met their match. Conceived at Nanyang Technological University, it comes in the form of a coating which has a magnetic-like feature that attracts bacteria and kills them without the need for antibiotics.

In
order to reactivate silenced genes, a cell needs to remove certain
“off” markers called methyl groups from the DNA. Scientists have
recently shown that this process involves an intermediate step and an
enzyme that also plays a role in the development of blood cancer. The
finding could lead to new ideas for cancer-fighting therapies.

A
pill that has long been used to treat HIV has moved one step closer to
becoming the first drug approved to prevent healthy people from becoming
infected with the virus that causes AIDS. The Food and Drug
Administration said Tuesday that Gilead Sciences' Truvada appears to be
safe and effective for HIV prevention.

Over the past several decades, scientists have faced challenges in developing new antibiotics even as bacteria have become increasingly resistant to existing drugs. One strategy that might combat such resistance would be to overwhelm bacterial defenses by using highly targeted nanoparticles to deliver large doses of existing antibiotics. In a step toward that goal, researchers have developed a nanoparticle designed to evade the immune system and home in on infection sites, then unleash a focused antibiotic attack.

When
the DNA double helix breaks, the broken end goes searching for the
similar sequence and uses that as a template for repair. Using a new
dual-molecule technique, a research group in the Netherlands has
found out how the DNA molecule is able to perform this search and
recognition process in such an efficient way.

Four
months ago the U.S. government sought to block publication of two
studies about how scientists created an easily spread form of bird flu.
Now a revised version of one paper is seeing the light of day with the
government's blessing. The second paper, which is more controversial
because it involves what appears to be a more dangerous virus, is
expected to be published later.

Industrial
biotechnology companies rely heavily on patents to attract investment
to fund R&D. The recent America Invents Act stands to have a
significant impact on technology innovators such as biotech firms, and
two recently published papers from patent law experts help explain the
extent of these shifts.
