New battery technologies take on lithium-ion

2015-07-22
(Press-News.org) Lithium-ion batteries remain the technology-of-choice for today's crop of electric cars, but challengers are revving up to try to upset the current order. An article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, takes a look at two of the top contenders vying to erode lithium-ion's dominance.

Alex Scott, a senior editor at C&EN, reports on two developments from companies in England that seem poised to compete in the electric car battery market within the next two to four years. One is a sodium-ion version, produced by a start-up called Faradion. The other is a battery powered by lithium-sulfur technology and is being developed by Oxis Energy. Both companies assert their advances will be able to compete with lithium-ion in performance, safety and costs.

Some industry watchers, however, remain unconvinced by the claims, given that a slew of other battery-makers made similar promises and then failed to deliver. Soon enough, the fates of Faradion and Oxis could also be determined.

Faradion has set a goal to match the energy density of lithium-ion batteries by 2017. And although they're still dealing with battery cycle issues, Oxis' lithium-sulfur technology has already attracted the attention of the military.

New material forges the way for 'stem cell factories'

New material forges the way for stem cell factories
2015-07-22
If you experience a major heart attack the damage could cost you around five billion heart cells. Future stem cell treatments will require this number and more to ensure those cells are replaced and improve your chances of survival. Experts at The University of Nottingham have discovered the first fully synthetic substrate with potential to grow billions of stem cells. The research, published in the academic journal Advanced Materials, could forge the way for the creation of 'stem cell factories' - the mass production of human embryonic (pluripotent) stem cells. The ...

Screening in pregnancy key to eliminating mother-to-child HIV transmission

2015-07-22
Canada has almost eliminated mother-to-child HIV transmission, known as vertical transmission, in recent years by ensuring that all women have the opportunity to be screened for HIV in pregnancy and that women with the disease receive treatment before giving birth. In 2014, there was only one recorded transmission of the virus to babies born to women known to be living with HIV. These findings were presented at the International AIDS Society 2015 conference in Vancouver by researchers from the Canadian Perinatal HIV Surveillance Program (CPHSP), a national group that ...

Poor survival in multiple myeloma patients linked to genetic variation

2015-07-22
SALT LAKE CITY- As part of a multi-institutional effort, researchers with Huntsman Cancer Institute at the University of Utah have found that multiple myeloma patients with a genetic variation in the gene FOPNL die on average 1-3 years sooner than patients without it. The finding was identified with a genetic mapping technique, genome wide association studies (GWAS), and verified in patient populations from North America and Europe. This was the first study to survey the entire human genome for genetic variation influencing survival, and included a total of 1,635 patients. Published ...

Novel scissor-like bridge structure for use during emergencies

Novel scissor-like bridge structure for use during emergencies
2015-07-22
A test of the Mobile Bridge® Version 4.0 (MB4.0) over a real river demonstrated its viability for practical use. During the test, the bridge was set up without any foundation work, and a vehicle could easily travel across it. This was achieved safely with very few people and without any problems. The MB4.0 viability test results were presented at a symposium of the Japan Society of Civil Engineers (JSCE) on June 23, 2015, by Dr. Ichiro Ario, Assistant Professor at the Institute of Engineering, Hiroshima University. Background of developing MB: Natural disasters include ...

Déjà-vu, new theory says dark matter acts like well-known particle

Déjà-vu, new theory says dark matter acts like well-known particle
2015-07-22
A new theory says dark matter acts remarkably similar to subatomic particles known to science since the 1930s. We owe a lot to dark matter - it is the thing keeping galaxies, stars, our solar system, and our bodies intact. Yet no one has been able to observe it, and it has often been regarded as a totally new exotic form of matter, such as a particle moving in extra dimensions of space or its quantum version, super-symmetry. Now an international group of researchers has proposed a theory that dark matter is very similar to pions, which are responsible for binding atomic ...

Researchers identify genetic mutation causing lethal condition in infants

2015-07-22
Bethesda, MD (July 22, 2015) -- Newborn children born with a mutation in the Plasmalemma Vesicle Associated Protein (PLVAP) gene develop severe protein losing enteropathy, according to a case study1 published in Cellular and Molecular Gastroenterology and Hepatology, the basic science journal of the American Gastroenterological Association. Protein losing enteropathy is a condition of the GI tract that results in loss of protein from the body, and often leads to severe abdominal swelling, malnutrition and early death in affected infants The investigators utilized next-generation ...

Gene knockout: Loss of a gene can be compensated by another gene

Gene knockout: Loss of a gene can be compensated by another gene
2015-07-22
This news release is available in German. New methods for modifying the genome are currently widely discussed: Using CRISPR/Cas for instance, scientists can remove parts of the genetic code of a gene, thereby knocking it out. Furthermore, there are ways to inhibit translation of a gene into a protein. Both methods have in common that they impede production of a protein and should therefore have comparable consequences for an organism. However, it has been shown that consequences can differ, after a gene is either knocked, out or only blocked. Scientist from the ...

Serum biomarkers can predict women at risk of pre-eclampsia

2015-07-22
Levels of biomarkers in the blood of pregnant women can be used to predict which women are at risk of pre-eclampsia, finds a study published today (22 July) in BJOG: An International Journal of Obstetrics and Gynaecology (BJOG). ADMA and Hcy, both known to be raised in women with pre-eclampsia, are present in the blood in higher than normal concentrations a month before the onset of the condition. Pre-eclampsia is a combination of raised blood pressure (hypertension) and protein in the urine (proteinuria). It is quite common, usually occurring after 20 weeks of pregnancy, ...

New research from Lawson uncovers important molecule in ovarian cancer

2015-07-22
Scientists at Lawson Health Research Institute have uncovered an important new target for ovarian cancer therapy. Contrary to current research this new study found that LKB1, a molecule that regulates the metabolism of many adult cells, is an important molecule in the cancer's promotion and survival. Thousands of women are living with ovarian cancer in Canada. It is estimated that this year, 2,800 Canadian women will be newly diagnosed with this disease. Even though ovarian cancer continues to be one of the most serious women's cancers, there is a real lack in reliable ...

MoveSense app makes cellphone an oxygen saturation monitor for heart and lung patients
2015-07-22
Patients suffering from chronic cardiopulmonary diseases could soon have a solution to help them accurately monitor their health and warn doctors at the first sign of trouble. By simply carrying their cellphone, equipped with the health-tracking app, MoveSense, developed by researchers at the University of Illinois at Urbana-Champaign, a patient's oxygen saturation level can be passively monitored with medical accuracy. Oxygen saturation is a standard measure of health status, the single most important clinical measure. Unlike other methods of measuring oxygen saturation ...
