UCLA Scientists Identify How Major Biological Sensor in the Body Works

Sensor Involved in Blood Pressure Regulation, Insulin Release, Brain Signaling

A biological sensor is a critical part of a human cell’s control system that is able to trigger a number of cell activities. A type of sensor known as the “gating ring” can open a channel that allows a flow of potassium ions through the cell’s wall or membrane — similar to the way a subway turnstile allows people into a station. This flow of ions, in turn, is involved in the regulation of crucial bodily activities like blood pressure, insulin secretion and brain signaling. (more…)

The Downside and Surprising Upside of Microcredit

Microcredit, which involves giving small loans to very small businesses in an effort to promote entrepreneurship, has been widely touted as a way to reduce poverty and stimulate economic growth. A multitude of both non- and for-profit institutions are spending billions of dollars each year on microcredit ventures in developing nations around the globe. (more…)

Leakage of Private Information from Popular Websites is Common, New Study Finds

*Co-Authored by WPI Computer Science Professor Craig Wills, Study Shows that Existing and Proposed Safeguards Against Leakage and Linking of Private Information are Inadequate*

A study of more than 100 popular websites used by tens of millions of people has found that three quarters directly leak either private information o r users’ unique identifiers to third-party tracking sites. The study, co-authored by Craig Wills, professor of computer science at Worcester Polytechnic Institute (WPI), also demonstrated how the leakage of private information by many sites, including email addresses, physical addresses, and even the configuration of a user’s web browser—so-called browser fingerprints—could permit tracking sites to link many disparate pieces of information, including browsing histories contained in tracking cookies and the contents of searches on health and travel sites, to create detailed profiles of individuals.

Air Quality Worsened by Paved Surfaces

Widespread urban development alters weather patterns

New research focusing on the Houston area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea. (more…)

Made in IBM Labs: Researchers Unveil Nanotechnology Circuits for Wireless Devices

*Scientists Build the First Wafer-Scale Graphene Integrated Circuit Smaller than a Pinhead*

Yorktown Heights, NY – 10 Jun 2011: Today, IBM Research scientists announced that they have achieved a milestone in creating a building block for the future of wireless devices. In a paper published yesterday in the magazine Science, IBM researchers announced the first integrated circuit fabricated from wafer-size graphene, and demonstrated a broadband frequency mixer operating at frequencies up to 10 gigahertz (10 billion cycles/second).

Designed for wireless communications, this graphene-based analog integrated circuit could improve today’s wireless devices and points to the potential for a new set of appli-cations. At today’s conventional frequencies, cell phone and transceiver signals could be improved, potentially allowing phones to work where they can’t today while, at much higher frequencies, military and medical personnel could see concealed weapons or conduct medical imaging without the same radiation dangers of X-rays.
