Medical Xpress / Mitochondria identified as key players in a rare disease causing microcephaly
Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate proportions and for cells to function correctly. When errors occur during cell division and the number ...
Dialog / What happens to cigarette butts after 10 years in the environment
Cigarette butts are the most common form of litter worldwide. Trillions are discarded every year in cities, parks, beaches, along railway tracks and roadside environments. Despite their small size, these remnants of smoked ...
Phys.org / Earth's toughest microbes could help save the planet and find life on other worlds
Extremophiles may well be tiny, but they are making a huge contribution to the health of our planet and our lives. A new review of these microorganisms, published in the journal Frontiers in Microbiology, explains how they ...
Medical Xpress / Nearly 30 million Americans bought guns after the pandemic, with 11 million becoming first-time gun owners
A national survey estimates that nearly 30 million U.S. adults acquired firearms between 2021 and 2024, including more than 11 million people who became gun owners for the first time. These new owners also introduced guns ...
Phys.org / Nest-building birds help disperse cotton further than wind, study suggests
Birds play a larger role in the dispersal of wild cotton than previously assumed. This is shown by a study in the journal Oikos, carried out in southern Africa. Researchers discovered that birds actively collect wild cotton ...
Phys.org / Ultrathin BiFeO₃ breaks the 30 nm limit, delivering fourfold stronger piezoelectricity
Piezoelectric materials, which convert mechanical stress into electricity and vice versa, are essential components in sensors, actuators, and energy-harvesting devices. However, the best piezoelectric materials, such as lead ...
Medical Xpress / Brain tumors hijack sugar metabolism to evade immune attack, study shows
Northwestern Medicine scientists have discovered that specialized immune cells within the glioblastoma tumor metabolize fructose to suppress immune responses and promote tumor growth, reports a study published in the Proceedings ...
Phys.org / How humans took over the planet: The role of cultural evolution
Humans really do rule the world. We took over fast and far, more than any other wild vertebrates. We inhabit nearly every corner of the world, and can thrive in deserts, tropical rainforests and even extremely cold climates. ...
Phys.org / Past intensive whaling threatens the future of bowhead whales
A unique collection of prehistoric bowhead whale bones, dating back 11,000 years, reveals a previously untold story of the relative impacts of humans on nature. The time series of ancient fossils show that commercial hunting ...
Phys.org / Proof-of-concept quantum battery shows faster charging as it gets larger
Australian scientists have made a significant leap forward in energy storage technology with the world's first proof-of-concept quantum battery. Similar to conventional batteries, this quantum version charges, stores and ...
Phys.org / Discrete time crystal acts as a usable sensor for weak magnetic oscillations
The bizarre properties of discrete time crystals could be harnessed to detect extremely subtle oscillations of magnetic fields, physicists in the US and Germany have revealed. Publishing their results in Nature Physics, a ...
Phys.org / Bow and arrow arrived about 1,400 years ago across western North America, study finds
A study clarifies the date of an important technological milestone: the adoption of the bow and arrow in western North America. The replacement of older weapons by bows and arrows occurred independently in several prehistoric ...
