Purdue University and USDA-Agriculture Research Service scientists trying to thwart the insect have identified Hessian fly genes that nullify toxins that wheat produces to protect itself from the munching larvae. The researchers report their findings in the Feb. 6 issue of the journal Proceedings of the National Academy of Sciences.

The study, conducted by Michael T. Smith, PhD, and colleagues at John’s Hopkins University, focused on 32 healthy females, who were studied polysomnographically for seven nights. On the first two nights, the subjects slept undisturbed for eight hours. Then, the women were assigned to one of three groups: Control, Forced Awakening (FA) and [...]
During flowering four different types of floral organs need to be formed: sepals, which protect the inner organs; the frequently ornamental petals; stamens, which produce pollen and the carpels. This process is orchestrated by a large number of genes. Scientists have now found that a small molecule, a so-called microRNA, is crucial for the control [...]
B cells are the antibody-producing cells of the body, which form the basis for the body’s recognition of foreign pathogens. B cells undergo a multi-staged maturation process, whereby variable segments of their genome are recombined in various different ways to produce the diversity of antigen recognition that underlies the immune system.
In their upcoming paper, [...]
Scientists from VIB, associated with the Katholieke Universiteit Leuven (K.U.Leuven), have revealed a new mechanism demonstrating the intricate ways in which plants deal with stress. The newly discovered control system has a remarkable way of orchestrating the activity of hundreds of genes, forcing the plant into ’safety mode’; the consumption of energy is contained while [...]
The team, based at MIT’s Center for Bits and Atoms, reports that the bubbles in their microfluidic device can carry on-chip process control information, just like the electronic circuits of a traditional microprocessor, while also performing chemical reactions. The work will appear in the Feb. 9 issue of Science.
Bubble logic merges chemistry with computation, allowing [...]
It should be noted that acute lymphoblastic leucemia is the most common oncological disease amongst children. This is why the application of this discovery could be highly beneficial for a special group of patients with this disorder %26ndash; those who show the cellular control pathway known as WNT as altered, - and whose prognosis of [...]
Because doctors sometimes have to inflict pain on their patients as part of the healing process, they also must develop the ability to not be distracted by the suffering, said Jean Decety, Professor in Psychology and Psychiatry at the University.
They have learned through their training and practice to keep a detached perspective; without such a [...]
Making its world debut at the Frankfurt Motor Show this week, Citroen’s C-Cactus is an eco-friendly concept car brimming with clever thinking and dramatic design. It is designed, says the French concern, to demonstrate how an extremely environmentally-sensitive design is feasible for a similar price to a conventional car.
