A tsetse fly's bite can be fatal: New research takes a step toward ending that
When an infected tsetse fly bites humans or other mammals to feed on their blood, microscopic parasites (African trypanosomes) in the fly's saliva are transferred. The unfortunate recipient of the bite, once infected, often faces severe health consequences, even death.

As our planet gets greener, plants are slowing global warming
Chi Chen, a Boston University graduate researcher, and Ranga Myneni, a BU College of Arts & Sciences professor of earth and environment, released a new paper that reveals how humans are helping to increase the Earth's plant and tree cover, which absorbs carbon from the atmosphere and cools our planet. The boom of vegetation, fueled by greenhouse gas emissions, could be skewing our perception of...

Seeking better guidelines for inventorying greenhouse gas emissions
In the face of a changing climate, the process of accounting greenhouse gas emissions is becoming ever more critical. Governments around the world are striving to hit reduction targets using Intergovernmental Panel on Climate Change (IPCC) guidelines to limit global warming. To have a chance of hitting these targets, they need to know how to accurately calculate and report emissions and removals.
First view of hydrogen at the metal-to-metal hydride interface
University of Groningen physicists have visualized hydrogen at the titanium/titanium hydride interface using a transmission electron microscope. Using a new technique, they succeeded in visualizing both the metal and the hydrogen atoms in a single image, allowing them to test different theoretical models that describe the interface structure. The results were published on 31 January in the journal...

Simplifying simple sequence repeats
Simple sequence repeats (SSRs) are regions of DNA with high diversity, and they have long been a mainstay for botanists examining the genetic structure of plant populations. However, as the cost of sequencing DNA continues to plummet and genetic technologies advance, newer techniques for mapping genetic diversity such as genotyping-by-sequencing (GBS) or RAD-seq have begun to rival the traditional...
Nanospirals that form as molten metals solidify could be key to new materials—and invisibility
Humans have been cooling metal mixtures from liquid to solid for thousands of years. But surprisingly, not much is known about exactly what happens during the process of solidification. Particularly puzzling is the solidification of eutectics, which are mixtures of two or more solid phases.
Black history month is not just a time to celebrate marches and martyrs

Study: Brexit referendum did not lead to more radical Euroskepticism elsewhere
Following the result of the UK Brexit referendum in June 2016 many Euroskeptic parties across Europe celebrated, contending that the vote could pave the way for similar referendums in other countries. This was explored in a paper, Eager to leave? Populist radical right parties' responses to the UK's Brexit vote, the lead author of which was Dr. Stijn van Kessel, Senior Lecturer in European...

Heat kills: We need consistency in the way we measure these deaths
One of the most confronting impacts of climate change is the risk of more deaths from hot weather. Heat stress can exacerbate existing health conditions including diabetes, kidney disease and heart disease. Older people are particularly vulnerable.
New cobalt complex could reduce the cost of hydroformylation
A team of researchers from Louisiana State University and ExxonMobil Chemical has found a way to replace the rhodium catalysts used in the hydroformylation process. In their paper published in the journal Science, the group describes their process and how it compares economically with current methods.
Not-so-dirty birds? Not enough evidence to link wild birds to food-borne illness
When food makes people sick, some blame birds because they hang around farms, and their feces can contain E. coli, Salmonella and Campylobacter, three common pathogens that can cause food-borne illness.
Exploring the school-age social, emotional, and behavioral health landscape
How you interact, how you feel, and how you act: The three basic tenants of social, emotional, and behavioral health are simple concepts, yet they can be some of the strongest predictors of well-being as children grow into adulthood. While a large number of children and adolescents meet the diagnostic criteria for mental health disorders, only a fraction actually receive needed services—and it...
Efficient cryopreservation of genetically modified rat spermatozoa
Rat spermatozoa are two to four times larger than that of other animal species and are easily damaged by changes in pH, osmotic pressure, and temperature. Because these animals are very frequently used in medical research, a cryopreservation method was developed nearly 20 years ago. However, rat spermatozoa motility after thawing is extremely poor, and unless artificial insemination is performed...
DNA extracted in museum samples can reveal genetic secrets
DNA in preserved museum specimens can allow scientists to explore the history of species and humanities impact on the ecosystem, but samples are typically preserved in formaldehyde which can damage DNA and make very difficult to recover.
Chemists simplify the synthesis of antitumor compounds
A RUDN chemist in collaboration with colleagues from N.D. Zelinsky Institute of Organic Chemistry and N.K. Koltsov Institute of Developmental Biology (IDB), RAS have developed a new method for the synthesis of isoxazole derivatives—substances that destabilize the process of cell division and potentially may become the basis for new anticancer drugs. The new method is based on the use of easily...

Your brain on Mars: How scientists will track astronauts' mental performance on missions
A journey to Mars is not going to be easy and there are a number of problems that need to be solved before we go. One interesting problem is how do we monitor the astronauts themselves. Of course, it is easy to monitor their heart rate and blood pressure, but is it possible to monitor what is going on inside their heads?
Inoculation theory: The vaccine for climate disinformation
Australia's recent bushfire crisis will be remembered for many things—not least, the tragic loss of life, property and landscape. But one other factor made it remarkable: the deluge of disinformation spread by climate deniers.
Media 'impartiality' on climate change is ethically misguided and downright dangerous
In September 2019, the editor of The Conversation, Misha Ketchell, declared The Conversation's editorial team in Australia was henceforth taking what he called a "zero-tolerance" approach to climate change deniers and skeptics. Their comments would be blocked and their accounts locked.
Exploring strangeness and the primordial Universe
Physicists believe that in the Universe's first ten microseconds free quarks and gluons filled all of spacetime, forming a new phase of matter named 'quark-gluon plasma' (QGP). Experimental and theoretical work at CERN was instrumental in the discovery of this hot soup of primordial matter, which is recreated today in accelerator-based lab experiments. To discover QGP in such experiments, the...
