Archaeological evidence suggests domestic canines bulked up between 8000 and 2000 years ago

Researcher Laura Rossi and her group at TU Delft have found a new way to build synthetic materials out of tiny glass particles—so-called colloids. Together with their colleagues from Queen's University and the University of Amsterdam, they showed that they can simply use the shape of these colloids to make interesting building blocks for new materials, regardless of other properties of the...

Prof Ulrike Tillmann on Andy Haldane’s suggestion that maths could be rebranded as numeracy to make it more approachableI read with interest your article in response to Andy Haldane’s comments suggesting maths could be rebranded as numeracy (Pass notes, 18 May). I welcome Mr Haldane’s support for the mathematical sciences and appreciate his intent to make the subject approachable to all....

Chemists' technique for turning cheap dicarboxylic acids into complex lactones could boost industries from pharmaceuticals to plastics.

One of the most tedious, daunting tasks for undergraduate assistants in university research labs involves looking hours on end through a microscope at samples of material, trying to find monolayers.

UK experts urge confirmed cases to avoid handling household pets as precautionary measurePeople with monkeypox have been told to avoid contact with their pets for three weeks amid concerns the animals could become infected and pass the virus on to other people.Monkeypox is caused by a viral infection and can be found in animals including rodents and monkeys, as well as in humans. It is typically...

With the carnage in Uvalde, Texas, and Buffalo, New York in May 2022, calls have begun again for Congress to enact gun control. Since the 2012 massacre of 20 children and four staff members at Sandy Hook Elementary School in Newtown, Connecticut, legislation introduced in response to mass killings has consistently failed to pass the Senate. We asked political scientists Monika McDermott and David...

Russia is reinventing decades-old propaganda based on supposed humanitarian principles to justify its invasion of Ukraine, according to research published in the peer-reviewed journal The International Spectator.

Any animal ascending a mountain experiences a double whammy of impediments: The air gets thinner as it also becomes colder, which is particularly problematic for creatures struggling to keep warm when less oxygen is available. For tiny animals with the highest-octane lifestyles, such as hovering hummingbirds, the challenges of relocating to higher levels to evade climate change may be too much,...

Americans have blamed many culprits, from mental illness to inadequate security, for the tragic mass shootings that are occurring with increasing frequency in schools, offices and theaters across the U.S.

Using a next generation sequencing analysis to examine human endogenous retrovirus (HERV) integration sites, researchers from Kumamoto University, the National Institute of Genetics (Japan), and the University of Michigan (U.S.) have discovered that these ancient retroviruses can undergo retrotransposition (DNA sequence insertion with RNA mediation) into iPS cells. The team believes that their...

Throughout history, mass gatherings such as collective rituals, ceremonies, and pilgrimages have created intense social bonds and feelings of unity in human societies. But Yale psychologists wondered if modern day secular gatherings that emphasize creativity and community serve an even broader purpose.

Chemists at Scripps Research have unveiled a method for turning cheap and widely available chemicals known as dicarboxylic acids into potentially very valuable molecules called lactones.

Chemical reactions that are driven by light offer a powerful tool for chemists who are designing new ways to manufacture pharmaceuticals and other useful compounds. Harnessing this light energy requires photoredox catalysts, which can absorb light and transfer the energy to a chemical reaction.

It is projected that by the year 2050, the global food supply will need to increase by 50-80% to keep up with the growing population. Researchers all over the world have been working to find ways to sustainably grow food crops to meet this need, and improving photosynthesis in plants holds great possibilities to solving these issues. 

Chromosomes undergo precise structural changes at a molecular level during the different phases of cell division. These changes occur at a high level of accuracy to prevent genome instability. Genome instability resulting from broken, missing, or rearranged chromosomes has been found to be the root cause of cell death, carcinogenesis, and congenital disorders. Studying genomic instability helps...

Due to global warming, temperatures in the Arctic are climbing rapidly. As a result, the treeline for Siberian larch forests is steadily advancing to the north, gradually supplanting the broad expanses of tundra which are home to a unique mix of flora and fauna. Experts from the Alfred Wegener Institute have now prepared a computer simulation of how these woods could spread in the future, at the...

A quantum system consisting of a large number of microscopic particles obeys statistical laws at the macroscopic level. In nature, there are two kinds of microscopic quantum particles. One is the boson satisfying the Bose-Einstein statistics, and the other is the fermion satisfying the Fermi-Dirac statistics.

Women feel more frustrated than men by the gendered expectations placed on them at work, even when those expectations appear to signal women's virtues and are seen as important for workplace advancement, according to new Cornell research.

Climate change debates on Reddit don't happen in polarized "echo chambers", new research suggests.

Terrorist attacks are highly responsive to local funding availability, and financial counter-terrorism can, thus, be effective in reducing terrorism casualties, according to new research by Nicola Limodio (Department of Finance, Bocconi University) forthcoming in Econometrica.

Jairo Kenupp Bastos first heard about the insect while visiting Canavieiras on the south coast of Bahia, a state in the Northeast of Brazil. "Local beekeepers told me about a tiny beetle that made holes in a plant called Dalbergia ecastaphyllum [Coinvine], a member of the pea family, and that the holes leaked a resin used by bees to make red propolis," said Bastos, a professor of pharmacognosy...

To keep order in the tight quarters of the cell nucleus, our DNA is neatly clamped in place around a central disk by H1 linker histone, which helps shepherd DNA into the tidy chromatin fibers that comprise chromosomes. Linker histone, however, is far more than a mere protein clip. Without sufficient H1, the process of gene transcription falters and the intricate dance of DNA repair screeches to a...
