For female mosquitoes, finding their next meal is all about smelling and seeing.
Through behavioral experiments and real-time recording of the female mosquito brain, a team of scientists, led by researchers at the University of Washington, has discovered how the mosquito brain integrates signals from two of its sensory systems -- visual and olfactory -- to identify, track and hone in on a potential host for her next blood meal.
When making decisions that are important to the species' survival, zebrafish choose mating over fleeing from a threat. This decision, different compared to that of some other species, appears to be controlled by specific brain regions that respond to pheromone cues.
The first rule on the stock market is to buy low and sell high. Economists are well aware of how this behaviour changes the prices of stocks, but in reality, trades alone don't tell the whole story. Parties like banks and insurance companies rarely trade stocks themselves; instead, they place orders for traders to do so on their behalf, which can be canceled at any time if they are no longer interested.
Korea Brain Research Institute (KBRI, President Seo Pan-ghill) announced on July 10 that the international joint research team where Senior Researcher Jeong Yoon-ha and John Hopkins School of Medicine collaborated, found that 'cell autophagy* gene' called ATG7 is related to the onset of frontotemporal dementia and Lou Gehrig's disease.
Autophagy: It refers to the phenomenon where a cell discomposes and recycles unnecessary organelles or components. It can be regarded as the self-cleaning taking place within the cell.
The art of tattooing may have found a diagnostic twist. A team of scientists in Germany have developed permanent dermal sensors that can be applied as artistic tattoos. As detailed in the journal Angewandte Chemie, a colorimetric analytic formulation was injected into the skin instead of tattoo ink. The pigmented skin areas varied their color when blood pH or other health indicators changed.
Robots and prosthetic devices may soon have a sense of touch equivalent to, or better than, the human skin with the Asynchronous Coded Electronic Skin (ACES), an artificial nervous system developed by a team of researchers at the National University of Singapore (NUS).
The new electronic skin system achieved ultra-high responsiveness and robustness to damage, and can be paired with any kind of sensor skin layers to function effectively as an electronic skin.
Over the last few decades, the exponential increase in computer power and accompanying increase in the quality of algorithms has enabled theoretical and particle physicists to perform more complex and precise simulations of fundamental particles and their interactions. If you increase the number of lattice points in a simulation, it becomes harder to tell the difference between the observed result of the simulation and the surrounding noise.
Researchers in the group of Jan Michiels (VIB-KU Leuven Center for Microbiology) identified a mechanism of how sleepy bacteria wake up. This finding is important, as sleepy cells are often responsible for the stubbornness of chronic infections. Findings published in Molecular Cell reveal new perspectives on how to treat chronic infections, for example by forcing bacteria to wake up.

Ribosomes are molecular machines that produce proteins in cells. Having finished the job, the ribosomes need regenerating. This process is important for the quality of the proteins produced and thus for the whole cell homeostasis as well as for developmental and biological processes. Biochemists from Goethe University Frankfurt together with biophysicists at LMU Munich have now watched one of the most important enzymes for ribosome recycling at work - ABCE1 - and shown that it is unexpectedly versatile in terms of structure.
Researchers have identified somatic mutations in the brain that could contribute to the development of Alzheimer's disease (AD). Their findings were published in the journal Nature Communications last week.
Decades worth of research has identified inherited mutations that lead to early-onset familial AD. Inherited mutations, however, are behind at most half the cases of late onset sporadic AD, in which there is no family history of the disease. But the genetic factors causing the other half of these sporadic cases have been unclear.
WASHINGTON, July 18, 2019 -- There are some crazy poisons in this world of ours, and they're often found in things you'd least expect. In this week's episode of Reactions, we break down our top five strangest poisons: https://youtu.be/4hQ0G0GaYR8.
ANN ARBOR, Michigan -- For oncologists in the beginning of their career, scientific conferences present an opportunity to network, share their research, gain new knowledge and begin to advance in their career. But many women find themselves skipping these conferences because of family obligations, a new study finds.
UCF student Veronica Urgiles has helped describe two new frog species discovered in Ecuador, and she named one of them after one of her professors.
Urgiles and an international team of researchers just published their findings in the journal ZooKeys.
MINNEAPOLIS, MN- July 18, 2019 - New University of Minnesota Medical School research is the first to show that estrogen is essential to maintaining muscle stem cell health.
