Predicting hot days in Europe
(Phys.org) -- 'Red sky at night, shepherd's delight, red sky in morning, fisherman's warning.' This saying is one of Europe's earliest rhymes that were used to predict weather for the following day. With advances in modern technology, from radar to satellite imagery, we can now predict weather well beyond the following day. European scientists have gone one step further, however, by predicting weather, not just days and weeks in advance, but a whole season ahead. Seasonal prediction can help us prepare against adverse weather conditions in the areas of agriculture, health and other industries. The findings were published in the journal Nature Climate Change.

NASA explains why clocks will get an extra second on June 30
If the day seems a little longer than usual on Saturday, June 30, 2012, that's because it will be. An extra second, or "leap" second, will be added at midnight to account for the fact that it is taking Earth longer and longer to complete one full turn--a day--or, technically, a solar day.
Explained: Near-miss asteroids (w/ Video)
On May 29, an asteroid the size of a bus came whizzing past Earth at 10 times the speed of a fired bullet. The near-miss asteroid, named 2012 KT42 — or “KT42” for short — streaked across the orbits of weather and television satellites, 22,000 miles above Earth’s surface, making it the sixth-closest asteroid approach on record. While the object had little chance of colliding with Earth, its approach gave scientists an opportunity to run a rapid-response program — or as MIT’s Richard Binzel calls it, an asteroid-tracking “fire drill” — to gain as much information as possible from the incoming space rock.
Curvy mountain belts
Mountain belts on Earth are most commonly formed by collision of one or more tectonic plates. The process of collision, uplift, and subsequent erosion of long mountain belts often produces profound global effects, including changes in regional and global climates, as well as the formation of important economic resources, including oil and gas reservoirs and ore deposits. Understanding the formation of mountain belts is thus a very important element of earth science research.

New research published in BioMed Central's open access journal Nutrition Journal has demonstrated that people who ate more dietary vitamin B12 and animal protein had lower levels of arsenic (measured by deposition in toenails). Total dietary fat, animal fat, vegetable fat and saturated fat were also all associated with lower levels of arsenic, while omega 3 fatty acids, such as those found in fish oil, were associated with increased arsenic.

Study identifies pathway to enhance usefulness of EGFR inhibitors in lung cancer treatment
Many lung cancers are driven by mutations in the epidermal growth-factor receptor (EGFR), and so it makes sense that many successful modern treatments block EGFR activity. Unfortunately, cancers inevitably evolve around EGFR inhibition, and patients with lung cancers eventually relapse. A University of Colorado Cancer Center study published today in the journal Cancer Research details a signaling pathway, known as 'the canonical Wnt pathway', that lung cancer cells use to escape from EGFR-targeted therapy – and suggests that by disrupting this pathway, we could lengthen the usefulness of existing EGFR inhibition therapies.
Researchers identify role of FOXO1 gene in Parkinson's disease
A recent study led by researchers at Boston University School of Medicine (BUSM) revealed that the FOXO1 gene may play an important role in the pathological mechanisms of Parkinson's disease.

'Ambient' bullying gives employees urge to quit
Merely showing up to work in an environment where bullying goes on is enough to make many of us think about quitting, a new study suggests. Canadian researchers writing in the journal Human Relations published by SAGE, have found that nurses not bullied directly, but who worked in an environment where workplace bullying occurred, felt a stronger urge to quit than those actually being bullied. These findings on 'ambient' bullying have significant implications for organizations, as well as contributing a new statistical approach to the field.

Insights into primate diversity: Lessons from the rhesus macaque
New research published in BMC Genetics shows that the rhesus macaque has three times as much genetic variation than humans. However despite much of this extra variation being within genes, it does not affect protein function. Consequently damaging variations are at similar levels in macaques and humans - indicating a strong selection pressure to maintain gene function regardless of mutation rate or population size.
Important new method probes dynamics of live microbial colonies in time, space
Microbes communicate by excreting simple and complex molecules called metabolites that interact with, talk to, and manipulate their local environment and neighboring cells in a process known as metabolic exchange. Understanding the timing and distribution of these molecular exchanges will be useful for interpreting and potentially manipulating microbial communities for applications ranging from bioremediation to drug discovery.

How an ancestral fungus may have influenced coal formation
(Phys.org) -- For want of a nail, the nursery rhyme goes, a kingdom was lost. A similar, seemingly innocuous change—the evolution of a lineage of mushrooms—may have had a massive impact on the carbon cycle, bringing an end to the 60-million year period during which coal deposits were formed.
New technique could reduce number of animals needed to test chemical safety
A new way of testing the safety of natural and synthetic chemicals has been developed by scientists with funding from the Biotechnology and Biological Sciences Research Council (BBSRC).

Making sense of molecular fragments
(Phys.org) -- Data from high-throughput next generation sequencers (NGS) and genome tiling arrays have greatly enhanced scientists’ ability to recreate RNA molecular structures, which is vital to disease and biotechnology research. However, high levels of noise and bias in some processes lead to uneven gene-expression values for segments belonging to the same molecule. Reconstructing the complete, or ‘full-length’, information of molecules as they occur in cells is therefore difficult.
Scientists urge new approaches to plant research
You'd be amazed at how much you can learn from a plant.
