Nitrogen limitation of CO2 fertilization: relief from fungal partners

New research shows that the stimulatory effect of atmospheric CO2 on plants depends on soil nitrogen and on the microbes that can help plants get it. More »

Using genome-scale models to predict biological capabilities

Rapid advances in DNA sequencing and synthesis technologies have revolutionized the study of life sciences. More »

Do plants have brains?

Many organisms have circadian clocks. These internal clocks play essential roles for predicting day-length or seasons, and they regulate behavior and hormonal secretion in animals More »

Zika virus infection during pregnancy and small heads: What is the connection and what can be seen by imaging

Within the last year, the outbreak of Zika virus infection in Brazil became a “public health emergency of international magnitude and concern”. More »


Menthol strengthens nicotine rewarding effects

Menthol is a monocyclic terpene alcohol that exists in plants of the Mentha genus. It is commonly known as mint. Menthol is a significant flavoring additive in tobacco products. Menthol-labeled cigarettes account for approximately one-quarter of the

Stanford team brings quantum computing closer to reality with new materials

Quantum computing could outsmart current computing for complex problem solving, but only if scientists figure out how to make it practical. A Stanford team is investigating new materials that could become the basis for such an advance.

An organic gas instead of inorganic gases for the enhancement of 129Xe magnetic resonance signals through optical pumping

Several new methods have been developed in these two decades in nuclear magnetic resonance (NMR) spectroscopy, which make us accessible to weak signals hitherto unmanageable because of the low sensitivity. Among them, spin-exchange optical pumping (SEOP) can

Isoporphyrins – Bioinspired NIR-Dyes

A contemporary concept in cancer therapy relies on the use of light and oxygen for cancer cell destruction. This process called Photodynamic Therapy, or shortly PDT, is mediated by suitable dyes, which are applied locally to the

Engineering native microbiome with stable symbionts: Novel approach to sustain agriculture

The depletion of biosphere resources and the ever-growing global human population have necessitated development of several strategies to sustainable agriculture and secure food safety . Applications of chemical fertilizers and development of transgenic plants have improved the

Role of fermented beverages in the maintenance of weight loss

Obesity is an increasingly prevalent disease and is associated with multiple chronic complications, such as diabetes mellitus, arterial hypertension, increased risk of cancer, etc. These complications may be ameliorated or even disappear after small but maintained weight

Decreased vagally-mediated heart rate variability in a conditional NPY Y1 receptor knockout mouse

Neuropeptide Y (NPY) is a protein involved in the complex regulation of a variety of physiological functions that range from feeding to emotions. In the central nervous system NPY is able to influence autonomic nervous system regulation

Plantar insensitivity and reduced cutaneous reflex strength: potential risk factors for balance impairment?

Sensory input arising from skin receptors of the foot sole provides important information for controlling standing balance: a finding demonstrated by blocking the neural activity of skin receptors in young adults. As we age, our skin receptors

Structure and function of the esophageal mucosa

Structure and function go hand-in-hand amongst the morphology, morphometry, biomechanics and secretory potential within the alimentary tract mucosa, submucosa and muscularis propria.  Structure must evolve first during the development of fetus and function follows closely and progressively

Cannabis reverses ageing processes in the brain

Researchers at the University of Bonn restore the memory performance of Methuselah mice to a juvenile stage. Memory performance decreases with increasing age. Cannabis can reverse these ageing processes in the brain. This was shown in mice

Green perspective in sample preparation prior to chromatographic analysis

Sample preparation is beyond any doubt the most demanding and at the same time the most challenging step of the analytical procedure, thus affecting the final performance of the whole analytical process in the analytical laboratory. Due

Glucocorticoids as a double-edge sword in the inflamed intestine

Chronic intestinal inflammation, in the form of the conditions ulcerative colitis and Crohn’s disease, is relatively common. Glucocorticoids (GCs) are the therapy of choice for the treatment acute flares of these diseases, but they have significant limitations,

Heavy alcohol drinking and potassium channel genes

Alcohol use disorder is a chronic and relapsing brain disease that has damaging, sometimes deadly, consequences for the individual and costs society billions of dollars a year (approximately $223 billion). Despite alcohol use being one of the

Warm is better than cold: hypothermia in abdominal aortic aneurysm surgery

Most of us agree shivering is unpleasant. In patients undergoing surgery for abdominal aortic aneurysm (AAA) falls in temperature below a certain level can make the difference between a good and poor outcome. An AAA is usually

Malrotation, a congenital condition that causes intestinal obstruction in infants, unusually presented in a 92 year old man

Malrotation is a rare condition that occurs when there is a problem during development of the gastrointestinal tract. The development of the intestines is a complex process that occurs during the 5th to 12th week of gestation.

Rapid monitoring of bacterial growth and antibiotic susceptibility with quantum semiconductor biochips

Public Health authorities sound the alarm over the increasing bacterial resistance to antibiotics and project a dark picture back to the pre-antibiotic era. One avenue of solutions proposed is to identify the spectrum of susceptibility to antibiotics
