CHICAGO—Chest pain and shortness of breath are common symptoms that send tens of thousands of heart failure (HF) patients into U.S. hospitals each month. Cardiologists at the Bluhm Cardiovascular Institute of Northwestern Memorial Hospital may be able to curb such visits for some of their HF patients as they recently became Chicago's first researchers using a new wireless pressure sensor technology that allows them to track the pulmonary artery pressure of the subjects while these subjects remain at home.

Physicists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder, have demonstrated a powerful new technique that reveals hidden properties of ultracold atomic gases.

CHAMPAIGN, Ill. — By combining stretchable optoelectronics and biologically inspired design, scientists have created a remarkable imaging device, with a layout based on the human eye.

As reported in the Aug. 7 issue of the journal Nature, researchers at the University of Illinois and Northwestern University have developed a high-performance, hemispherical "eye" camera using an array of single-crystalline silicon detectors and electronics, configured in a stretchable, interconnected mesh.

EVANSTON, Ill. --- Digital cameras have transformed the world of photography. Now new technology inspired by the human eye could push the photographic image forward even more by producing improved images with a wider field of view.

Black girls who undergo gender and culturally tailored HIV interventions are significantly less likely to contract a sexually transmitted disease.

The study by Emory University public health researchers is being presented at the International AIDS Conference in Mexico City. It analyzed the self-reported sexual behavior and condom usage among 439 sexually active black female girls between the ages of 15 and 21.

ALEXANDRIA, VA, August 6, 2008---The American Physical Therapy Association (APTA) is urging parents and caregivers to ensure that babies get enough "tummy time" throughout the day while they are awake and supervised, in light of a recent survey of therapists who say they've noticed an increase in motor delays in infants who spend too much time on their backs while awake.

CHAMPAIGN, Ill. — According to new research, old ideas about water behavior are all wet.

Ubiquitous on Earth, water also has been found in comets, on Mars and in molecular clouds in interstellar space. Now, scientists say this common fluid is not as well understood as we thought.

Aphids are emerging as sentinels of climate change, researchers at BBSRC-supported Rothamsted Research have shown. One of the UK's most damaging aphids – the peach-potato aphid (Myzus persicae) – has been found to be flying two weeks earlier for every 1°C rise in mean temperature for January and February combined. This year, the first aphid was caught on 25 April, which is almost four weeks ahead of the 42-year average. This work is reported in BBSRC Business, the quarterly research highlights magazine of BBSRC (the Biotechnology and Biological Sciences Research Council).

A Johns Hopkins expert in HIV and how the AIDS virus hides in the body says antiretroviral drugs have stopped HIV from replicating, the first of three key steps needed to rid people of the virus.

In an address to be delivered Aug. 6 at the XVII International Conference on AIDS, taking place in Mexico City, infectious disease specialist Robert Siliciano, M.D., Ph.D., says current drug-combination therapies can stop HIV in its tracks, with some combos suppressing its ability to make copies to less than one in a billion.
