Yersinia pestis, the bacterium that causes bubonic plague, can survive within the ubiquitous soil protozoan, the amoeba, by producing proteins that protect against the latter microbe's digestion, report scientists.
Modern metabolic science yields better way to calculate indoor carbon dioxide
The air we breathe out can help us improve the quality of the air we breathe in. But to do so, one needs a reliable way to calculate the concentration of carbon dioxide we produce indoors. Researchers have developed a new computation method that uses well-established concepts from the study of human metabolism and exercise physiology to significantly improve how this important data is derived.
Helpful tool allows physicians to more accurately predict parathyroid cancer recurrence

Thin layers of water hold promise for the energy storage of the future
Researchers have found that a material which incorporates atomically thin layers of water is able to store and deliver energy much more quickly than the same material that doesn't include the water layers. The finding raises some interesting questions about the behavior of liquids when confined at this scale and holds promise for shaping future energy-storage technologies.

Special 'nugget-producing' bacteria may hold the key to more efficient processing of gold ore, mine tailings and recycled electronics, as well as aid in exploration for new deposits, research has shown.
Weather extremes and trade policies were main drivers of wheat price peaks
Price peaks of wheat on the world market are mainly caused by production shocks such as induced for example by droughts, researchers found. These shocks get exacerbated by low storage levels as well as protective trade policies, the analysis of global data deriving from the US Department of Agriculture shows. In contrast to widespread assumptions, neither speculation across stock or commodity markets nor land-use for biofuel production were decisive for annual wheat price changes in the past four decades.
No, complex is not complicated -- it is rather simple
The simplest experimental system to date to identify the minimum requirements for the emergence of complexity has been developed.
Fast, low energy, and continuous biofuel extraction from microalgae

Francisco Goya is the most important Spanish artist of the late 18th and early 19th century. In 1793, Goya, then 46, came down with a severe, undiagnosed illness. His hearing never returned. Now, a hearing expert has developed a diagnosis. She thinks Goya likely suffered from an autoimmune disease.
Solar system: New insights into ring system
Astronomers have modeled the two rings around Chariklo, the smallest body in the Solar System known to have rings. This is the first time an entire ring system has been simulated using realistic sizes for the ring particles. The simulation revealed that the ring particles are much smaller than predicted or that an undiscovered shepherd satellite around Chariklo is stabilizing the ring.
Success in the 3-D bioprinting of cartilage
A team of researchers has managed to generate cartilage tissue by printing stem cells using a 3-D-bioprinter. The fact that the stem cells survived being printed in this manner is a success in itself. In addition, the research team was able to influence the cells to multiply and differentiate to form chondrocytes (cartilage cells) in the printed structure.

England's cancer drugs fund 'failed to deliver meaningful value to patients and society'
Analysis of the drugs that were approved for use by the NHS Cancer Drugs Fund (CDF) in England has shown that the fund was not good value for patients and society and may have resulted in patients suffering unnecessarily from toxic side effects of the drugs.
Symptoms of cystitis probably caused by bacterial infection, even when tests are negative
The majority of women suffering with pain when urinating, or needing to urinate often or urgently probably do have a bacterial infection, even when nothing is detected by standard urine testing.
Symbiotic bacteria: From hitchhiker to beetle bodyguard
Bacterial symbionts transition between plant pathogenicity and insect defensive mutualism, a new report demonstrates. The bacterium Burkholderia gladioli lives in specific organs of a plant-feeding beetle and defends the insect's eggs from detrimental fungi by producing antibiotics. However, when transferred to a plant, the bacterium can spread throughout the tissues and negatively affect the plant.

There is an age-related decline in children’s physical activity levels as they progress through primary school, according to a British study.
New appetite control mechanism found in brain
A newly discovered molecule increases appetite during fasting, and decreases it during gorging. The neuron-exciting protein, named NPGL – apparently aims to maintain body mass at a constant, come feast or famine. An evolutionary masterstroke, but not great news for those looking to trim down, or beef up for the summer.

The difficulties of prioritizing preventable disease and long term health issues in post conflict zones are explored in a new report.
Single gene encourages growth of intestinal stem cells, supporting 'niche' cells, and cancer
A gene previously identified as critical for tumor growth in many human cancers also maintains intestinal stem cells and encourages the growth of cells that support them, according to results of a study. The finding adds to evidence for the intimate link between stem cells and cancer, and advances prospects for regenerative medicine and cancer treatments.
Female partners can help facilitate early melanoma detection in men over 50, research shows
Men over 50 have a higher risk than the general population of developing melanoma, the deadliest form of skin cancer, so they need to keep a sharp eye out for signs of the disease. Many women in this age group, however, would attest that they’re more likely than their male partners to notice suspicious spots on the skin — which means women could help save their male partners’ lives by helping them spot skin cancer.
Artificial intelligence shows potential to fight blindness
Researchers have found a way to use artificial intelligence to fight a complication of diabetes that affects the eyes.
Study quantifies kidney failure risk in living kidney donors
Researchers have developed a risk calculator that estimates the risk of kidney failure after donation. Overall risk was low, but black race and male sex were associated with increased risks of developing kidney failure in living kidney donors. Older age was associated with greater kidney failure risk in nonblack donors, but not in in black donors. Higher BMI and a close biological relationship to the recipient were also associated with increased risks of kidney failure.
Overweight/obese people with diabetes at increased risk of brain abnormalities
Overweight and obese individuals with early stage type 2 diabetes (T2D) had more severe and progressive abnormalities in brain structure and cognition compared to normal-weight study participants, research indicates.
Protein 'spy' gains new abilities
A method to rapidly trigger the universal tagging of proteins being produced by a cell has now been discovered by researchers. The tagging can be turned on like a switch, which enables researchers to acquire a snapshot of proteins being produced by a cell at a given time.
Food insecurity can affect your mental health
Food insecurity (FI) affects nearly 795 million people worldwide. Although a complex phenomenon encompassing food availability, affordability, utilization, and even the social norms that define acceptable ways to acquire food, FI can affect people's health beyond its impact on nutrition. A new study determined that FI was associated with poorer mental health and specific psychosocial stressors across global regions (149 countries), independent of individuals' socioeconomic status.
Left-handed people are more likely to have a slender face
Individuals with a slender lower face are about 25 percent more likely to be left-handed. This unexpected finding was identified in 13,536 individuals who participated in three national surveys conducted in the United States. This association may shed new light on the origins of left-handedness, as slender jaws have also been associated with susceptibility to tuberculosis, a disease that has shaped human evolution and which today affects 2 billion people.
