Phys.org / Simulations hint at a hidden population of companionless black holes

So far, almost all stellar-mass black holes detected by astronomers have been found in binary systems. However, astronomers have long suspected that these binary black holes are the exception and that, within the Milky Way, ...

Phys.org / New quantum encryption method prevents ciphertext from being cloned

Digital security currently relies on difficult equations to protect data. For example, when you use a credit card online, the information is locked inside a math problem that would take a modern computer thousands of years ...

Phys.org / New models shed light on how an exotic phase of hydrogen in Earth's core may behave

While Earth's core consists mostly of iron, its density implies that lighter elements are also mixed in. Because hydrogen is abundant in the universe and can mix with iron under certain conditions, scientists suspect it makes ...

Phys.org / A 21-hour dip could help explain Tabby's star's decade-long dimming mystery

Since 2016, an ordinary-looking F-type star called KIC 8462852, nicknamed Tabby's star, has behaved anything but ordinarily. In a new study published in the Monthly Notices of the Royal Astronomical Society on July 6, researchers ...

Phys.org / New museum find shows nature can't stop inventing seahorses

At first glance, it looks exactly like a seahorse. It has the same horse-shaped head tilted down from the body, the same curled, grasping tail and, in the males, a fully enclosed pouch for brooding the young.

Phys.org / Geological evidence questions the role of Agulhas Leakage in Atlantic Ocean circulation

For decades, scientists have asserted that the leakage of warm, salty Indian Ocean water south of South Africa into the Atlantic is a major contributor to the Atlantic Meridional Overturning Circulation (AMOC), a component ...

Phys.org / Rising seas are inundating US coastal wetlands, putting many on track to become open water

Along the three coasts of the contiguous United States, a silent race unfolds. Fueled by climate change, sea levels rise faster than at any time in recent geologic history. Meanwhile, coastal wetlands cling to a slim lead, ...

Phys.org / Homo antecessor skull layers resemble modern humans and Neanderthals, fragments suggest

A new study provides quantitative data on cranial vault thickness in Homo antecessor, based on the analysis of three parietal fragments recovered from the Gran Dolina site in the Sierra de Atapuerca, Burgos, Spain.

Phys.org / Bringing it all into focus—computational microscope captures 25.2 billion pixels per second across a wide field of view

When designing microscopes, optical engineers have long faced a trade-off between speed, field of view and resolution. But improving one of these properties typically comes at the expense of another. Now, a UC Berkeley–led ...

Phys.org / Stomach stone hypothesis sheds light on the evolution of dinosaur digestive systems

An international research team led by Assistant Professor Ryuji Takasaki of the Faculty of Biosphere-Geosphere Science at Okayama University of Science has published a paper proposing a new hypothesis on the evolutionary ...

Phys.org / Male sperm whales produce loudest communication sounds ever measured in any mammal

Deep in the world's oceans, large male sperm whales emit slow, low-frequency clicks with the highest source levels of any animal communication sounds. These slow clicks are not the echolocation clicks the whales use to locate ...

Phys.org / Mechanical shortcut' rapidly carries organic particles into the deep ocean

The processes that capture carbon from the atmosphere and store it on the seabed are crucial for climate balance. However, assessing these mechanisms is often complicated because it requires measurements ranging from the ...
