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.
Accelerating chemical reactions without direct contact with a catalyst
A Northwestern University research team has revealed a new approach to conducting chemical reactions—one that doesn't require direct contact with a catalyst.
Space station's cosmic detector working after 4 spacewalks
The cosmic detector that required a series of difficult spacewalking repairs is back in action.
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...
Mega-constellation firms meet European astronomers
Scientists put their concerns about giant satellite networks directly to the companies involved.
Advertisers can digitally add product placements in TV and movies — tailored to your digital footprint
New tech lets advertisers insert virtual products into finished TV and films, using your online data to tailor the placement to the viewer. Could that mean E.T. ends up eating your favourite candy, and not Reese's Pieces? And how will viewers...
One big eye on the sky closes, but bigger one is on the way
The Spitzer space telescope brought us new images of the cool universe
Wreckage of ship tied to Bermuda Triangle found off Florida
Scientists have found the wreckage of a cargo steamship that became associated with the Bermuda Triangle when it disappeared in 1925 off the Atlantic Coast of Florida.
Global science team on red alert as Arctic lands grow greener
New research techniques are being adopted by scientists tackling the most visible impact of climate change—the so-called greening of Arctic regions.
Ultra-high energy events key to study of ghost particles
Physicists at Washington University in St. Louis have proposed a way to use data from ultra-high energy neutrinos to study interactions beyond the standard model of particle physics. The 'Zee burst' model leverages new data from large neutrino telescopes such as the IceCube Neutrino Observatory in Antarctica and its future extensions.
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...

New research techniques are being adopted by scientists tackling the most visible impact of climate change - the so-called greening of Arctic regions. The latest drone and satellite technology is helping an international team of researchers to better understand how the vast, treeless regions called the tundra is becoming greener.

Physicists propose a new way to leverage data from ultra-high energy neutrinos from large neutrino telescopes such as the IceCube Neutrino Observatory in Antarctica. So far, all nonstandard interaction studies at IceCube have focused only on the low-energy atmospheric neutrino data.
Britons on evacuation flight from Wuhan tell of relief and confusion
Some forced to leave behind loved ones due to short notice after China lifted restrictionsCoronavirus: live updatesBritons who were on board the evacuation flight from Wuhan have spoken of the confusion surrounding their departure, with some still having to leave loved ones behind.The flight, carrying 87 Britons and 27 foreign nationals from the coronavirus-hit Chinese city, touched down at RAF...

Theoretical physicists have found a deep link between one of the most striking features of quantum mechanics -- quantum entanglement -- and thermalization, which is the process in which something comes into thermal equilibrium with its surroundings.
How supercomputers are helping us link quantum entanglement to cold coffee
Theoretical physicists from Trinity College Dublin have found a deep link between one of the most striking features of quantum mechanics—quantum entanglement—and thermalisation, which is the process in which something comes into thermal equilibrium with its surroundings.
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
February 1st marks the start of Black History Month. While many people are familiar with iconic figures such as Martin Luther King Jr., Rosa Parks and Harriet Tubman, there are many other lesser known African-Americans, whose achievements should also be recognized.
Young people putting music to the crisis: The role of music as a political expression
Songs that Sing the Crisis: Music, Words, Youth Narratives and Identities in Late Modernity is the title of a special issue of the journal Young (Nordic Journal of Youth Research) to be published on 1 February, now available online, that reflects on the role of music as an expression of the crisis. It contains case studies of musical genres rap, punk, folk metal, black metal, fado, reggaeton and...
