Viewpoints: Obama's 'olive branch' on birth control coverage; Sen. Kirk recounts his stroke therapy; Nurses oppose mandatory flu shots

The Obama administration released the final details Friday of the exemption it will provide religious-affiliated employers from the requirement to include free birth control in employees' insurance policies. Not surprisingly, the announcement didn't seem to mollify any of the critics who'd been arguing that the exemption was inadequate.

Study shows how placental circulation can influence malarial parasite behavior and infection

Malaria in pregnancy causes a range of adverse effects, including abortions, stillbirths, premature delivery and low infant birth weight. Many of these effects are thought to derive from a placental inflammatory response resulting from interaction of infected red blood cells with the placental tissue.

Researchers determine differences in stiffness between healthy and cancerous tissue

The texture of breast cancer tissue differs from that of healthy tissue. Using a cutting-edge tissue diagnostic device, a group of researchers in Basel, Switzerland, has determined one key difference: cancerous tissue is a mix of stiff and soft zones, whereas healthy tissue has uniform stiffness.

TB test offers rapid detection of TB and drug-resistant strains according to new study

A diagnostic test for tuberculosis (TB) can accurately and quickly detect both TB and drug-resistant strains, according to a new study. The authors of a new systematic review assessing the diagnostic accuracy of the Xpert® MTB/RIF test published in The Cochrane Library say their study can provide timely advice for clinicians and policymakers in countries where TB is a major public health problem.

Insight into mechanical properties that break the outer segment of photoreceptors

Light-sensing cells in the eye rely on their outer segment to convert light into neural signals that allow us to see. But because of its unique cylindrical shape, the outer segment is prone to breakage, which can cause blindness in humans. A study published by Cell Press on January 22nd in the Biophysical Journal provides new insight into the mechanical properties that cause the outer segment to snap under pressure.

New details about molecular surveillance system that helps detect and correct errors in cell division

Studies led by cell biologist Thomas Maresca at the University of Massachusetts Amherst are revealing new details about a molecular surveillance system that helps detect and correct errors in cell division that can lead to cell death or human diseases. Findings are reported in the current issue of the Journal of Cell Biology.

Scientists compare neuronal network connections in 2 worm species

Researchers in the group of Ralf Sommer at the Max Planck Institute for Developmental Biology in Tuebingen, Germany, have for the first time been able to identify neuronal correlates of behaviour by comparing maps of synaptic connectivity, or "connectomes", between two species with different behaviour.

Scientists determine structure of Ltn1 protein

Using an innovative approach, scientists at The Scripps Research Institute (TSRI) have determined the structure of Ltn1, a recently discovered "quality-control" protein that is found in the cells of all plants, fungi and animals.

Viewpoints: Health law's 'sticker shock;' Changing Medicare eligibility age is not a simple solution

President Obama said a fair bit during the fiscal-cliff negotiations - speaking for 45 minutes in one 50-minute meeting, for example - but today let's zero in on the claim he kept repeating: "We don't have a spending problem. We have a health-care problem." For our money - and yours - those are two of the most remarkable sentences our Orator in Chief has ever strung together.

DESI technique identifies cancer type, grade and tumor margins in brain surgery patients

A new tool that could allow for faster, more comprehensive testing of brain tissue during surgery successfully identified the cancer type, grade and tumor margins in five brain surgery patients, according to a Purdue University and Brigham and Women's Hospital study.

Combination of pazopanib and paclitaxel shows promise in slowing anaplastic thyroid cancer

A combination of the drugs pazopanib and paclitaxel shows promise in slowing anaplastic thyroid cancer (ATC), according to a Mayo Clinic-led study published in the journal Science Translational Medicine.

Partin Tables to predict prostate cancer spread now updated

Prostate cancer experts at Johns Hopkins have developed an updated version of the Partin Tables, a tool to help men diagnosed with prostate cancer and their doctors to better assess their chance of a surgical cure. The updated tool, based on a study of more than 5,600 men treated at The Johns Hopkins Hospital from 2006 to 2011, is published in the Jan. 3 issue of the British Journal of Urology International.

Itch-specific nerve cells in skin discovered by John Hopkins scientists

Johns Hopkins researchers have uncovered strong evidence that mice have a specific set of nerve cells that signal itch but not pain, a finding that may settle a decades-long debate about these sensations, and, if confirmed in humans, help in developing treatments for chronic itch, including itch caused by life-saving medications.

Researchers study response of living cells to artificial protein

One approach to understanding components in living organisms is to attempt to create them artificially, using principles of chemistry, engineering and genetics. A suite of powerful techniques-collectively referred to as synthetic biology-have been used to produce self-replicating molecules, artificial pathways in living systems and organisms bearing synthetic genomes.

Researchers demonstrate significance of two proteins in nerve cell development

The study conducted by Prof. Frank Bradke's team provides indications on brain development and about the causes of diseases of the nervous system. The results have now been published in "Neuron".
