The unintended consequences of centralized blood banking and what to do about it

Science Daily - Mon, 23/01/2017 - 4:15pm
In the late 1990s, the World Health Organization (WHO) issued a policy requiring the establishment of centralized blood banking facilities in Sub-Saharan African countries. One researcher says that this policy is now having unintended negative consequences.

Immune defense without collateral damage

Science Daily - Mon, 23/01/2017 - 4:12pm
Researchers have clarified the role of the enzyme MPO. In fighting infections, this enzyme, which gives pus its greenish color, produces a highly aggressive acid that can kill pathogens without damaging the surrounding tissue. The findings may provide new approaches for immunity strengthening therapies.

Identifying early markers of cardiac dysfunction in pregnancy

Science Daily - Mon, 23/01/2017 - 4:03pm
Preeclampsia, which affects 3-8 percent of all pregnancies, is a disease specific to pregnancy that is characterized by high blood pressure and protein in the urine. Research studies have clearly shown that there is a link between a history of preeclampsia in a pregnancy and developing heart disease later in life. In fact, a history of preeclampsia is as much of a risk factor for heart disease as a lifetime of smoking cigarettes and the American Heart Association now screens women specifically for a history of preeclampsia. The issue is that, while this association is clearly known, not all women with a history of preeclampsia will develop heart disease. Additionally, we do not know the exact process that takes place from the time women experience preeclampsia to the ultimate development of heart disease.

More People Than Ever Are Using DuckDuckGo; Site Says It Observed 14M Searches in One Day This Month

Slashdot - Mon, 23/01/2017 - 4:00pm
An anonymous reader shares a BetaNews article: A lot of people are more privacy aware than they have been in the past, and are wary of entrusting everything they search for to Google. That's where privacy-focused sites like DuckDuckGo come in. Its growth since it launched 8 years ago has been nothing short of staggering, with the number of searches skyrocketing since 2013, when Edward Snowden first revealed how the US government was spying on its people. The search site says it has to date served up over 10 billion anonymous searches, with 4 billion of those occurring in the last year alone, and the company says it is growing faster than ever. On January 10 2017, the site received in excess of 14 million private searches.

Ultrafast Camera Captures 'Sonic Booms' of Light for First Time

Space.com - Mon, 23/01/2017 - 3:30pm
Just as aircraft flying at supersonic speeds create cone-shaped sonic booms, pulses of light can leave behind cone-shaped wakes of light. Now, a superfast camera has captured the first-ever video of these events.

Every Upcoming Chromebook Will Run Android Apps

Slashdot - Mon, 23/01/2017 - 3:20pm
Google announced last year that it will be bringing Android apps to Chromebooks. The company has now announced that moving forward all the new Chromebooks will have access to the Google Play Store, the marquee store for Android apps. From a report: The news comes from a single line of text in Google's list of Chromebooks that can support the programs: "All Chromebooks launching in 2017 and after as well as the Chromebooks listed below will work with Android apps in the coming future." We knew this would eventually come, and now isn't terribly surprising timing. There are more Chromebooks with touchscreens than ever, including the Asus Chromebook Flip C302CA and Samsung's upcoming Chromebook Plus and Pro, all of which were announced at CES in Las Vegas.

Cervical cancer mortality rates may be underestimated

Science Daily - Mon, 23/01/2017 - 2:47pm
A new analysis reveals that for most women, the risk of dying from cervical cancer is higher than previously thought. Unlike prior estimates that also included women who had undergone a hysterectomy and were therefore no longer at risk, this analysis only included women with a cervix. The study also revealed significant racial differences in the risk of dying from cervical cancer.

Use of fetal genetic sequencing increases the detection rate of genetic findings

Science Daily - Mon, 23/01/2017 - 2:47pm
Researchers have found that, in preliminary data, fetal genomic (whole exome) sequencing (WES) as a diagnostic test for women with pregnancies complicated by major fetal congenital anomalies increased the detection rate of genetic findings by between 10 to 30 percent.

Melting solid below the freezing point

Science Daily - Mon, 23/01/2017 - 2:47pm
Researchers have discovered a new phenomenon of so-called metastability in a liquid phase. This state is common in supercooled liquids, which are liquids that cool below the freezing point without turning into a solid or a crystal. These scientists report the first experimental evidence of creating a metastable liquid directly by melting a high-pressure solid crystal of the metal bismuth via a decompression process below its melting point.

Glucose supplementation significantly reduces length of induced labor in childbirth

Science Daily - Mon, 23/01/2017 - 2:47pm
Prolonged labor can be harmful to maternal and fetal health. Few medical interventions are known to shorten labor duration. Because muscle performance is known to be improved by glucose supplementation, the researchers tested whether adding glucose to the intravenous hydration solution women receive during labor could accelerate labor.

Skin closure options for cesarean delivery: Glue vs. subcuticular sutures

Science Daily - Mon, 23/01/2017 - 2:47pm
Cesarean delivery rates have increased during the last few decades and it has become the most common surgery during a woman's reproductive years. There is currently no definite evidence regarding the best method for skin closure after a cesarean surgery. Safety of the operation, healing and cosmetic outcomes are important and should influence the physician's choice of skin closure methodology.

Day of delivery linked to maternal-fetal mortality

Science Daily - Mon, 23/01/2017 - 2:47pm
Based on data from the Centers for Disease Control and Prevention, the United States maternal mortality ratio is three to four times higher than that of most other developed nations. The maternal mortality ratio is increasing, reaching 21-22 per 100,000 live births in 2014 (more than double from 1990.) Although much has been written about this problem, few solutions have been forthcoming.

Evaluation of the effects of laser tissue welding for spina bifida repair

Science Daily - Mon, 23/01/2017 - 2:47pm
Spina Bifia is a birth defect where there is incomplete closure of the backbone and membranes around the spinal cord. It affects more than 4,000 children born each year in the U.S. and is associated with hydrocephalus (excessive accumulation of fluid on the brain), developmental delay, lifelong disability and death. This preliminary study hoped to determine the effects of laser tissue welding on underlying skin and spinal cord tissue.
