Determining the major drivers of species diversification and phenotypic innovation across the Tree of Life is one of the grand challeges in evolutionary biology.
Facilitated by the Germplasm Bank of Wild Species of the Kunming Institute of Botany (KIB) of the Chinese Academy of Sciences (CAS), Prof. YI Tingshuang and Prof. LI Dezhu of KIB led a novel study on gymnosperm diversification with a team of international researchers.
Computer vision has progressed much over the past decade and made its way into all sorts of relevant applications, both in academia and in our daily lives. There are, however, some tasks in this field that are still extremely difficult for computers to perform with acceptable accuracy and speed. One example is object tracking, which involves recognizing persistent objects in video footage and tracking their movements. While computers can simultaneously track more objects than humans, they usually fail to discriminate the appearance of different objects.
A new Tel Aviv University study found that, like humans, bats living in Tel Aviv enjoy the wide variety and abundance of food that the city has to offer, in contrast to rural bats living in Beit Guvrin, who are content eating only one type of food. The study was led by research student Katya Egert-Berg, under the guidance of Prof. Yossi Yovel, head of Tel Aviv University's Sagol School of Neuroscience and a faculty member of the School of Zoology in the George S.
Using advanced remote sensing techniques can help the early detection of oak tree decline and control many other forest diseases worldwide, says new research from Swansea University.
For decades, researchers around the world have searched for ways to use solar power to generate the key reaction for producing hydrogen as a clean energy source -- splitting water molecules to form hydrogen and oxygen. However, such efforts have mostly failed because doing it well was too costly, and trying to do it at a low cost led to poor performance.
New York, NY--July 19, 2021-- A new robotic neck brace from researchers at Columbia Engineering and their colleagues at Columbia's Department of Otolaryngology may help doctors analyze the impact of cancer treatments on the neck mobility of patients and guide their recovery.
Politicians may have good reason to turn to angry rhetoric, according to research led by political scientists from Colorado--the strategy seems to work, at least in the short term.
In a new study, Carey Stapleton at the University of Colorado Boulder and Ryan Dawkins at the U.S. Air Force Academy discovered that political furor may spread easily: Ordinary citizens can start to mirror the angry emotions of the politicians they read about in the news. Such "emotional contagion" might even drive some voters who would otherwise tune out of politics to head to the polls.
Researchers at the University of Maryland School of Medicine (UMSOM) launched a new online tool that could more quickly advance medical discoveries to reverse progressive hearing loss. The tool enables easy access to genetic and other molecular data from hundreds of technical research studies involving hearing function and the ear. The research portal called gene Expression Analysis Resource (gEAR) was unveiled in a study last month in Nature Methods.
Why do alterations of certain genes cause cancer only in specific organs of the human body? Scientists at the German Cancer Consortium (DKTK), the Technical University of Munich (TUM), and the University Medical Center Göttingen have now demonstrated that cells originating from different organs are differentially susceptible to activating mutations in cancer drivers: The same mutation in precursor cells of the pancreas or the bile duct leads to fundamental different outcomes.
WINSTON-SALEM, NC, JULY 19, 2021 -- Wake Forest researchers and clinicians are using patient-specific tumor 'organoid' models as a preclinical companion platform to better evaluate immunotherapy treatment for appendiceal cancer, one of the rarest cancers affecting only 1 in 100,000 people. Immunotherapies, also known as biologic therapies, activate the body's own immune system to control, and eliminate cancer.
A new mathematical model helps predict the tiny changes in carbon-based materials that could yield interesting properties.
Scientists at Tohoku University and colleagues in Japan have developed a mathematical model that abstracts the key effects of changes to the geometries of carbon material and predicts its unique properties.
The details were published in the journal Carbon.
Researchers from the Paul Scherrer Institute PSI and the Brookhaven National Laboratory (BNL), working in an international team, have developed a new method for complex X-ray studies that will aid in better understanding so-called correlated metals. These materials could prove useful for practical applications in areas such as superconductivity, data processing, and quantum computers. Today the researchers present their work in the journal Physical Review X.
Germany is not meeting its legal obligations to protect refugee women and girls from discrimination. This is the conclusion of a "shadow report" by the University of Göttingen, the association Pro Asyl and the refugee councils of Bavaria, Hesse, Lower Saxony and Saxony-Anhalt. Shadow reports are a useful tool to present important information in parallel with official government reports.
"The project's main objective is to integrate a certain degree of automation, so that an operator can control a small fleet of up to 10 drones from a single ground station," says Luis E. Moreno, LABYRINTH's coordinator and researcher at the UC3M's Robotics Lab. "The idea is that the operator indicates the mission to be undertaken (for example, monitoring traffic in a particular area) and the system automatically converts this mission into a set of routes that each drone has to follow, automatically calculating alternative routes when necessary," he explains.
This summer, if you see a butterfly with wings that are blue on top with orange spots underneath, you may have crossed paths with a male European Common Blue (or Polyommatus icarus), a newly introduced species in Canada.
Could it be a fluke? Probably not, according to a group of researchers from the University of Ottawa who have taken a close look at this captivating blue creature. They are in fact the first to study its ecology.
