Coherence stands as a pillar of effective communication, whether it is in writing, speaking or information processing. This principle extends to quantum bits, or qubits, the building blocks of quantum computing. A quantum computer could one day tackle previously insurmountable challenges in climate prediction, material design, drug discovery and more. A team led by the U.S. Department of Energy’s (DOE) Argonne National Laboratory has achieved a major milestone toward future quantum computing. They have extended the coherence time for their novel type of qubit to an impressive 0.1 milliseconds — nearly a thousand times better than the previous record. “Rather ...

ITHACA, N.Y. – Researchers from the Charles H. Dyson School of Applied Economics and Management have developed a new method for measuring food insecurity, which for millions of people in the U.S. is more than just an abstract concept. The group’s probability of food security (PFS) measures the likelihood that a household’s food expenditures equal or exceed the minimum cost of a healthful diet. The researchers then put the PFS to the test, analyzing food security dynamics over a recent 17-year period, and found that a third of U.S. households experienced at least temporary food insecurity. Seungmin Lee, a doctoral student in the field of applied economics and management, ...

Long-term consumption of water with fluoride levels far above established drinking water standards may be linked to cognitive impairments in children, according to a new pilot study from Tulane University. The study, published in the journal Neurotoxicology and Teratology, was conducted in rural Ethiopia where farming communities use wells with varying levels of naturally occurring fluoride ranging from 0.4 to 15.5 mg/L. The World Health Organization recommends fluoride levels below 1.5 mg/L. Researchers ...

Inflammation is a risk factor for many chronic diseases, including cardiovascular disease (CVD), and the impact of diet on inflammation is an area of growing scientific interest. In particular, recommendations to limit red meat consumption are often based, in part, on old studies suggesting that red meat negatively affects inflammation – yet more recent studies have not supported this. “The role of diet, including red meat, on inflammation and disease risk has not been adequately studied, which can lead to public health recommendations that are not based on strong evidence,” said Dr. Alexis Wood, associate professor of pediatrics – ...

Bacteriophages, also called phages, are viruses that infect and kill bacteria, their natural hosts. But from a macromolecular viewpoint, phages can be viewed as nutritionally enriched packets of nucleotides wrapped in an amino acid shell. A study published October 26th in the open access journal PLOS Biology by Jeremy J. Barr at Monash University, Victoria, Australia, and colleagues suggests that mammalian cells internalize phages as a resource to promote cellular growth and survival. Phage interactions with bacteria are well known, and interactions between bacteria and their mammalian host can lead ...

New research from the University of Birmingham shows that the electronic structure of metals can strongly affect their mechanical properties. The research, published today (26th October) in the journal Science, demonstrates experimentally, for the first time, that the electronic and mechanical properties of a metal are connected. It was previously understood theoretically that there would be a connection, but it was thought that it would be too small to detect in an experiment. Dr Clifford Hicks, Reader in Condensed Matter Physics, who worked on the study said: “Mechanical properties are typically described ...

Semiconductors—most notably, silicon—underpin the computers, cellphones, and other electronic devices that power our daily lives, including the device on which you are reading this article. As ubiquitous as semiconductors have become, they come with limitations. The atomic structure of any material vibrates, which creates quantum particles called phonons. Phonons in turn cause the particles—either electrons or electron-hole pairs called excitons—that carry energy and information around electronic devices to scatter in a matter of nanometers and femtoseconds. This means that energy is lost in the form of heat, and that information transfer has ...

To date, research has suggested that only humans and some species of toothed whales live many years of active life after the loss of reproductive ability. But now, a new study shows female chimpanzees in Uganda show signs of menopause – surviving long past the end of their ability to reproduce. Signs of menopause in wild chimpanzees may provide insights into the evolution of this rare trait in humans. The vast majority of mammals stay fertile until the very ends of their lives, with humans and several species of toothed whales as the outliers; they experience menopause. In humans, menopause ...

For the first time in human history, say Daniel Gervais and John Nay in a Policy Forum, nonhuman entities that are not directed by humans – such as artificial intelligence (AI)-operated corporations – should enter the legal system as a new “species” of legal subject. AI has evolved to the point where it could function as a legal subject with rights and obligations, say the authors. As such, before the issue becomes too complex and difficult to disentangle, “interspecific” legal frameworks need to be developed by which AI can be treated as legal subjects, they write. Until now, the legal system has been univocal ...

While small, the hypothalamus – a complex structure located deep in the brain – plays a gargantuan role in coordinating the wide array of neuronal signals that are responsible for keeping the body in a stable state. In a Special Issue of Science, authors across four Reviews unpack this key brain region’s impact on physiological and behavioral homeostasis. The hypothalamus consists of a complex collection of neural circuits. These circuits receive, process, and integrate sensory inputs to drive coordinated communication via a range of behavioral, ...

In a Perspective, Stephen Tang and Samuel Sternberg discuss retroelement-based gene editing as a safer alternative to CRISPR-Cas approaches. Precision genome editing technologies have transformed modern biology. Capabilities for programable DNA targeting have improved rapidly, largely due to the development of bacterial RNA-guided CRISPR-Cas systems, which allow precise cleavage of target DNA sequences. However, CRISPR-Cas9 systems generate a DNA double strand break (DSB), which activates cellular DNA repair pathways that can lead to unwanted and complex byproducts, ...

Key takeaways Female chimpanzees in Uganda’s Ngogo community experienced a menopausal transition similar to women. Fertility among chimpanzees studied declined after age 30, and no births were observed after age 50. The data can help researchers better understand why menopause and post-fertile survival occur in nature and how it evolved in the human species.  A team of researchers studying the Ngogo community of wild chimpanzees in western Uganda’s Kibale National Park for two decades has published a report in Science showing that females in this population can ...

The hardness of materials is determined by the strength of the chemical bonds that are formed between the electrons of the neighbouring atoms.  For example, the bonds in diamond are very strong, so it is one of the hardest materials known.  The bonding is rooted in the laws of quantum mechanics, and the complex compounds that are of most interest in forefront research today are known as ‘quantum materials.’  In many quantum materials, layers of strongly bonded atoms separate layers in ...
