Moore's Law, originating in 1965 [1], is an observation of transistor density on a single CPU core increasing exponentially with time. Futurists such as Ray Kurzweil [2] extend this to the claim that CPU-core computation rate (operations per second) will also increase exponentially with time, allowing for a technological explosion of super-intelligent machines in soon-to-come decades.

A team of researchers have published new data that could prove vital for advances in care for women who suffer from recurrent miscarriage.

The recurrent loss of pregnancy through miscarriage causes significant distress to couples, often exacerbated by there being so few treatments available to clinicians.

The search for an effective treatment has been the cause of significant controversy in the field of medical research, centering on the role of natural killer cells (or NK cells) and the ability of steroids to prevent miscarriage.

Scientists have been uncertain about how these NK cells could contribute to a miscarriage and this has raised doubt over their importance in causing pregnancy loss.

20 years ago, El Niño had an uncorrected impact on the data that went into global warming models, causing puzzling results. Now, those results have been corrected and instead of El Niño impacting global warming, global warming could be impacting El Niño.

Using coral samples from Kiribati, researchers have outlined how El Niño Southern Oscillation (ENSO) cycle has changed over the past 4,300 years - altering the cycles of El Niño and La Niña events that bring extreme drought and flooding to Australia and many other Pacific-rim countries. The new paper suggests that external changes have an impact on the strength and timing of El Niño events.

Last week I met Marek Karliner at the ICNFP 2013 conference in Crete, where we both enjoyed a nice friendly atmosphere, great food, and a wonderful peaceful location. Professor Marek Karliner is the chair of the Institute of Theoretical Physics of Tel Aviv in Israel. Since he agrees that outreach in physics is an important service that researchers should provide to the community, I was able to convince him to write for this blog the short article which you find below, on the interesting topic of baryons containing two heavy quarks - TD.

The human brain is adept at linking seemingly random details into a cohesive memory that can trigger myriad associations — some good and some not so good.

For recovering addicts or individuals with post-traumatic stress disorder (PTSD), unwanted memories can make recovery difficult. For example, former meth addicts report intense drug cravings triggered by associations with cigarettes, money, even gum, which makes them more likely to stumble during recovery.

Scientists have been able to erase drug-associated memories in mice and rats without affecting other more benign memories. Their discovery points to a clear and workable method to disrupt unwanted memories while leaving the rest intact.

Changing the Structure of Memory

Since Medicaid paid for 45 percent of the 4 million births in the United States in 2010, and that has been rising steadily, a new paper says that the Affordable Care Act (ACA) and expanding Medicaid even more may lead to improved coverage of well-woman and maternity care — and perhaps result in better health outcomes.

Previously, data on Medicaid funding of births did not exist in a comprehensive form so the authors collected all such data on Medicaid births from individual states during the years 2008 to 2010.

Dingoes have been unfairly blamed for the extinctions of the Tasmanian tiger (thylacine) and the Tasmanian devil, a new study has found.

The Australian dingo is commonly blamed for the demise of thylacines and devils on the mainland about 3,000 years ago but Aboriginal populations and a shift in climate were more likely responsible.

The researchers created mathematical models to replicate the dynamic interaction between the main potential drivers of extinction (dingoes, climate and humans), the long-term response of herbivore prey, and the viability of the thylacine and devil populations.

The models included interactions and competition between predators as well as the influence of climate on vegetation and prey populations.
