Limits on Stem-Cell Research Re-emerge as a Political Issue

May 6, 2004

The debate over embryonic stem-cell research is re-emerging as an election issue as advocates for patients, including Nancy Reagan and 206 members of the House, press the president to loosen the limits on federal financing for the science.

CPR: Mouth-to-Mouth Not Much Help

March 19, 2007

For adults who suddenly collapse, CPR is more effective if rescuers focus on chest compression over mouth-to-mouth ventilation.

By interrupting lifesaving chest compressions, mouth-to-mouth resuscitation may do more harm than good.

Hot nanotube sheets produce music on demand

November 3, 2008

Sheets made of carbon nanotubes behave like a loudspeaker when zapped with a varying electric current, say researchers at Tsinghua University in Beijing and could lead to new generation of cheap, flat speakers and even talking clothing.

The sound is generated by the thermoacoustic effect. The flexible nanotube sheets can be stretched or flexed into complicated shapes and still produce sound, and when fully stretched, the sheets are transparent… read more

McGreevey Signs Bill Creating Stem Cell Research Institute

May 13, 2004

Saying that the frontiers of medical science should not be hemmed in by politics, New Jersey Gov. James E. McGreevey signed legislation Wednesday to establish the nation’s first state-supported stem cell research facility.

The action made New Jersey the only state other than California to provide funds for the research, and came as the Bush administration faces increasing pressure to relax its restrictions.

Making silicon devices responsive to infrared light

January 6, 2014

silicon_infrared

A new system developed by researchers at five institutions, including MIT, could eliminate many limitations in methods to develop detectors that are responsive to a broad range of infrared light. Such detectors could form sensitive imaging arrays for security systems, for example.

The new system works at room temperature and provides a broad infrared response, says associate professor of mechanical engineering Tonio Buonassisi.

Nanoparticles cross blood-brain barrier, enhance medication delivery and MRI performance

May 2, 2012

Researchers at Harvard-affiliated McLean Hospital have developed a new category of non-toxic, protein-based ”green” nanoparticles that can non-invasively cross the blood brain barrier and transport various types of drugs.

In an article published May 1, 2012 online in PLoS ONE, Gordana Vitaliano, MD, director of the Brain Imaging NaNoTechnology Group at the McLean Hospital Imaging Center, reported that clathrin protein, a ubiquitous protein found in human,… read more

Helping blind students ‘see’ nanoscale objects

3-D plaster model of "NanoBucky" showing the individual carbon nanofibers

To give blind students a feel — literally — for nanoscience and technology, University of Wisconsin-Madison scientists are building three-dimensional models of nano-surfaces that are large enough to be explored with the hands.

They used a rapid prototyping printer, which lays down plaster layer-by-layer to “print” 3-D models.

Obama Election Ushering In First Internet Presidency

November 7, 2008

The Obama administration is expected to build on a foundation of grassroots support in his private social network, on Facebook, YouTube, and Twitter, and a similar social networking for his legislative initiatives, recruiting supporters to lobby Congress to get his policies enacted into law.

CIA’s spy tools make Maxwell Smart’s look like toys

May 28, 2004

The CIA’s future information analysis technologies will make Google look like a toy. In-Q-Tel’s investments provide a glimpse of what they might do.

  • Tacit Knowledge Systems’ software could facilitate information sharing by scanning every agent’s outgoing e-mail, looking for clusters of words that tell the system what and who each agent seems to know. And MetaCarta can figure out where the information is about.

    Flexible Batteries That Never Need to Be Recharged

    April 4, 2007

    European researchers have integrated thin-film organic solar cells with a flexible polymer battery to produce a lightweight and ultrathin solar battery for low-wattage electronic devices, such as smart cards and mobile phones.

    The battery can recharge itself when exposed to natural or indoor sunlight, meaning that some electronic gadgets would never need a separate charger. Researchers predict that such a device could be commercially available in some products next… read more

    Will the Next Ice Age Be Permanent?

    November 13, 2008

    The world may be witnessing the final stages of a 50-million-year transition from a planet with a persistent warm climate and scant polar ice to one with greatly expanded ice sheets at both poles, two climatologists suggest in Nature.

    The Nature paper goes on to propose that humans, as long as they have a technologically powerful society, would be likely to avert such a slide into a long big… read more

    Embryos Yield New Stem Cell Lines

    June 10, 2004

    Scientists at a Chicago fertility clinic isolate 12 new lines from genetically flawed human embryos. The research could lead to increased understanding of genetic diseases.

    The embryos had gene mutations for two forms of muscular dystrophy, certain blood diseases and a cause of mental retardation — seven diseases in all.

    US military plans to put internet router in space

    April 15, 2007

    The US military plans to test an internet router in space, in a project that could also benefit civilian broadband satellite communications.

    Potential non-military benefits of DoD’s Internet Routing In Space (IRIS) program include the ability to route IP traffic between satellites in space in much the same way packets are moved on the ground, reducing delays, saving on capacity and offering greater networking flexibility.

    Quantum calibration paves way for super-secure communication

    November 18, 2008

    A new approach to calibrating quantum mechanical measurement has allowed scientists to calibrate a detector that can sense the presence of multiple individual photons.

    This means that devices that rely on information being transmitted via light, such as the fiber-optic technologies used in everyday communications, could detect the safe arrival of that light energy with an unprecedented level of accuracy, leading to ultra-secure communications technologies in the future via… read more

    Nano Killers Aim at Mini Tumors

    June 23, 2004

    Kereos is developing nanotechnologies to identify tumors that measure just 1 mm in diameter, then kill them with a tiny but precise amount of a chemotherapy drug.

    The biomarker being used is a group of four proteins that signal that a tumor needs to recruit blood vessels, a process called angiogenesis.
