Orangutans can make two separate sounds simultaneously, much like songbirds or human beatboxers, according to a study. Adriano Lameira and Madeleine Hardus observed vocalizing orangutans in the wild. Humans use the lips, tongue, and jaw to make the unvoiced sounds of consonants, while activating the vocal folds in the larynx with exhaled air to make the voiced, open sounds of vowels. Orangutans are capable of producing both types of sounds—and both at once. For example, large male orangutans in Borneo will produce noises known as “chomps” in combination with “grumbles” in combative situations. Females in Sumatra produce “kiss squeaks” atop ...

In a time of income inequality and ruthless politics, people with outsized power or an unrelenting willingness to browbeat others often seem to come out ahead. New research from Dartmouth, however, shows that being uncooperative can help people on the weaker side of the power dynamic achieve a more equal outcome—and even inflict some loss on their abusive counterpart. The findings provide a tool based in game theory—the field of mathematics focused on optimizing competitive strategies—that could be applied to help equalize the balance of power in labor negotiations or international ...

INDIANAPOLIS – Colorectal cancer incidence and deaths are declining for individuals age 50 and older, but are increasing for those under 50. A new study, led by researcher-clinician Thomas Imperiale, M.D., of the U.S. Department of Veterans Affairs, Regenstrief Institute and Indiana University School of Medicine, identifies seven risk factors for early onset colorectal cancer in males. The risk evaluation model the researchers developed may help 45- to 49-year-olds accept and adhere to new national screening recommendations and may also identify younger men for whom earlier screening should be considered. “This study is important because ...

Diminished anthropogenic pollutant emissions during 2020 Covid-19 lockdowns reduced snowmelt in the Himalayas, according to a study. Liqiang Zhang and colleagues used multiple satellite data from the Moderate Resolution Imaging Spectroradiometer (MODIS) and Ozone Monitoring Instrument (OMI), as well as a coupled atmosphere-chemistry-snow model (GEOS-Chem-SNICAR) to explore how the sudden, dramatic reduction in particulate pollution in the region affected snow and ice melt. Snow and ice on the Tibetan plateau act as a water source for over 20% of the global population. However, ice and snow in the Himalayas have been melting at an accelerating rate in recent decades. ...

Iron is the most abundant element by mass on Earth. Despite being so common and well-studied, iron still manages to puzzle scientists by exhibiting electric and magnetic behaviors that are not fully comprehensible. In particular, the physical properties of liquid iron—which makes up most of the Earth’s core—have been the subject of much debate among physicists and geoscientists. The problem is that certain predictions about liquid iron’s properties are difficult to experimentally verify due to the extreme conditions required to ascertain them. For example, liquid iron’s resistivity, which is the inverse of electrical conductivity, has ...

Supramolecular polymers are a new class of polymers that are currently being evaluated for material applications. These interesting compounds also play an important role in cellular activities in the body. "Supra," as the name suggests, is attributed to some unique properties that go beyond those of conventional polymers. Unlike traditional polymers, which are held together by strong, irreversible covalent bonds, supramolecular polymers are held together by weaker, reversible hydrogen bonds. They can reversibly assemble and disassemble, are highly versatile, and can be used for developing targeted drug delivery therapies, sensors to detect pollutants, diagnostic ...

WASHINGTON—People who have just one or two drinks per day are not protected against endocrine conditions such as obesity and type 2 diabetes, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism. Alcohol consumption is a significant public health concern because it is related to many medical conditions such as diabetes, obesity, liver conditions and heart disease. While it is widely accepted that excessive alcohol consumption causes a wide range of health issues, whether modest alcohol consumption has beneficial health effects remains controversial. “Some research ...

Copenhagen, Denmark: More women are having just one embryo transferred per cycle of fertility treatment to get pregnant, according to research presented at the 39th annual meeting of the European Society of Human Reproduction and Embryology (ESHRE) [1]. Preliminary data from the ESHRE European IVF-monitoring Consortium (EIM) [2] shows that nearly three in five (57.6%) out of all in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) procedures in 2020 in Europe involved the transfer ...

Copenhagen, Denmark: A new artificial intelligence (AI) tool can identify sperm in severely infertile men in seconds compared to the hours it takes scientists, according to results presented today (Tuesday) at the 39th annual meeting of the European Society of Human Reproduction and Embryology (ESHRE) [1].   The study authors say the algorithm they have developed brings hope to men who want a biological child but have no sperm in their semen.   Currently, these patients must undergo a procedure where a portion of their testes is removed to help them become fathers. Embryologists extract sperm manually from this biopsy sample to fertilise the partner’s eggs ...

Recurrent bouts of systemic lupus erythematosus, marked by the body’s immune system attack of its own tissues, closely tracked with measureable upticks in growth in the gut of a certain species of bacteria. New research from NYU Grossman School of Medicine shows that bacterial blooms of the gut bacterium Ruminococcus blautia gnavus occurred at the same time as disease flare-ups in five of 16 women with lupus of diverse racial backgrounds studied over a four-year period. Systemic lupus erythematosus involves damaging inflammation, especially in the kidneys, but also in joints, skin, and blood vessels. ...

EL PASO, Texas (June 27, 2023) ­– Step aside self-driving cars, self-driving boats are here — and they can do more than take you on a cruise.  Researchers at The University of Texas at El Paso have constructed a fully autonomous boat that can carry out bathymetric surveys — surveys of the depth and terrain of bodies of water like oceans, rivers and lakes. The team hopes the robotic boat can help simplify the survey process, which usually takes a crew of individuals to complete, as well as assist ...

Researchers led by Katsunori Tanaka at the RIKEN Cluster for Pioneering Research (CPR) in Japan and Hiromitsu Haba at the RIKEN Nishina Center for Accelerator-Based Science (RNC) have developed a new technique that has the potential to generically treat several kinds of cancer, with fewer negative side effects than currently available methods. Published on June 27 in Chemical Science, the proof-of-concept study showed that tumors in mice grew almost three times less and survival was 100% after just one injection of a compound that is designed to emit small amounts of alpha radiation from the inside of cancer cells, thus killing them but sparing ...

In October, the excavation work for the superlative construction project began. What some consider an ideal ecological city, others call a promotional gimmick. Researchers from the Complexity Science Hub now show why The Line should not be a showcase for future cities.    "It's the embodiment of the dream to start from scratch and completely rethink a city," says  Rafael Prieto-Curiel, who researches cities at the Complexity Science Hub. The Line is planned to be a city built from nothing in the desert. It is to consist of two gigantic, unbroken rows of skyscrapers, with living space in between. 170 kilometers long. 200 meters wide. 500 meters high, higher ...

Magnetotactic bacteria, which can align with the Earth’s magnetic field, have been discovered in a new location. Previously observed on land and in shallow water, analysis of a hydrothermal vent has proven that they can also survive deep under the ocean. The bacteria were able to exist in an environment that was not ideal for their typical needs. Magnetotactic bacteria are of interest not only for the role they play in Earth’s ecosystem, but also in the search for extraterrestrial life. Evidence of their existence can remain in rocks for billions of years. Their magnetic inclinations can also provide ...
