Seismic waves generated by earthquakes travel through Earth's solid iron inner core faster in the direction of the rotation axis than along the equator. UC Berkeley scientists created a core growth model to explain this. To fit seismic data, the model predicts that asymmetric growth of the core leads to crystal movement that preferentially aligns iron-nickel crystals north-south. The model implies that the core is only 0.5-1.5 billion years old, a fraction of Earth's age.

The impact of deploying Artificial Intelligence (AI) for radiation cancer therapy in a real-world clinical setting has been tested by Princess Margaret researchers in a unique study involving physicians and their patients.

Dogs may have earned the title "man's best friend" because of how good they are at interacting with people. Those social skills may be present shortly after birth rather than learned, a new study by University of Arizona researchers suggests.

In the world of quantum mechanics, researchers can even make empty space, the lack of something, do their bidding. Scientists from the Katsaros group at the Institute of Science and Technology (IST) Austria together with an international team of researchers have now created a new setup to control the absence of electrons in a solid material. They want to use these holes as a basis for a quantum computer.

What The Study Did: Changes in pregnancy and birth rates before and after COVID-19 lockdown measures were estimated using electronic medical records.

Patients who, perhaps unbeknownst to their health care providers, are in need of genetic testing for rare undiagnosed diseases can be identified en masse based on routine information in electronic health records (EHRs), a research team reported today in the journal Nature Medicine.

Whales are largely protected from direct catch, but many populations' numbers still remain far below what they once were. A study published in the journal Current Biology on June 3 suggests that, in addition to smaller population sizes, those whales that survive are struggling. As evidence, they find that right whales living in the North Atlantic today are significantly shorter than those born 30 to 40 years ago.

Anyone that's ever interacted with a dog knows that they often have an amazing capacity to interact with people. Now researchers reporting in the journal Current Biology on June 3 have found that this ability is present in dogs from a very young age and doesn't require much, if any, prior experience or training. But, some of them start off better at it than others based on their genetics.

Using a piece of magnet, researchers have designed a simple system that can control the movement of a small puddle of water, even when it's upside down. The new liquid manipulation strategy, described in the journal Cell Reports Physical Science on June 3, can have a wide range of applications including cleaning hard-to-reach environments or delivering small objects.

Making quantum networks a reality relies crucially on building efficient optical fiber-based quantum light sources. Here, scientists in Germany present an advanced manufacturing approach to accomplish this task. Femtosecond 3D printing is used to create complex micrometer-sized optics to both enhance the single-photon extraction efficiency of semiconductor quantum dots and couple their emission into single-mode optical fibers. This compact on-chip solution enables high coupling efficiency into a single-mode fiber with high-rate single-photon emission.

The system offers an economical way to source essential battery material.

Controlling coherent interaction between optical fields and quantum systems in scalable, integrated platforms is essential for quantum technologies. A German-British research team has developed an on-chip hollow-core light cage that could provide a platform for quantum-storage and quantum-nonlinear applications. Showing stable non-degrading performance and extreme versatility, the laterally accessible light cage could be a compelling candidate for all-on-chip, integrable, low-cost, vapor-based photon delay.

College students who engaged in four or more high-impact practices such as study abroad or internships have a 70% chance of either enrolling in graduate school or finding a full-time job after graduating with a bachelor's degree, finds a new University at Buffalo study. These practices - such as study abroad, internships, undergraduate research, community service, first-year seminars and capstone courses - have the greatest influence on college success, regardless of student or family background.

A recent study by a team of researchers led by Yale-NUS researcher Dr. Vinod Kumar Saranathan has discovered a novel way to manufacture single gyroid photonic crystals to work in the visible light spectrum, based on the self-assembly mechanism found in blue-winged leafbirds.

A research team led by Osaka University precisely set the number of layers in multilayer graphene nanoribbons, controlling the semiconducting and metallic properties of field effect transistors and establishing a design guideline for the practical applications of graphene devices.

Disruptions from sea-level rise and coastal flooding events have significant indirect impacts on urban traffic networks and road safety.

A dash of milk could make all the difference to a healthy heart as new research from the University of South Australia finds that people who regularly consume milk have a lower risk of heart disease.

New research shows that diet, including fish oil supplements, can alter not only the breast microbiome, but also breast cancer tumors. The study appears online in Cancer Research, a journal of the American Association for Cancer Research.

Amid the steady growth of solar energy production in the United States, pollinator conservation at solar installations has become an appealing secondary pursuit, but the long-term success of such efforts remains to be seen. In a new article published today in the journal Environmental Entomology, a group of entomologists say pairing solar energy with pollinator habitat offers great promise, but scientific evaluation and meaningful standards will be key to making it a true win-win combination.

A highly-detailed VLA image indicates that the jets of material propelled outward by young stars much more massive than the Sun may be very different from those ejected by less-massive young stars.
