How sex trafficking trauma affects the way its survivors parent

A study of young immigrant mothers who are survivors of sex trafficking found that the trauma affected how they parented: It made them overprotective parents in a world perceived to be unsafe, it fueled emotional withdrawal when struggling with stress and mental health symptoms, and was a barrier to building confidence as mothers. Yet, they coped with such challenges through finding meaning in the...

Study points to a seed black hole produced by a dark matter halo collapse

Supermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun. The Milky Way hosts an SMBH with mass a few million times the solar mass. Surprisingly, astrophysical observations show that SMBHs already existed when the universe was very young. For example, a billion solar mass black holes are found when the universe was just 6% of its...

Researchers uncover unique properties of a promising new superconductor

An international team of physicists led by the University of Minnesota has discovered that a unique superconducting metal is more resilient when used as a very thin layer. The research is the first step toward a larger goal of understanding unconventional superconducting states in materials, which could possibly be used in quantum computing in the future.

Pioneering chemistry approach could lead to more robust soft electronics

A new approach to studying conjugated polymers has made it possible for an Army-funded research team to measure, for the first time, the individual molecules' mechanical and kinetic properties during polymerization reaction. The insights gained could lead to more flexible and robust soft electronic materials, such as health monitors and soft robotics.

The give and take of mega-flares from stars

The long relationships between stars and the planets around them—including the Sun and the Earth—may be even more complex than previously thought. This is one conclusion of a new study involving thousands of stars using NASA's Chandra X-ray Observatory.

Exploring the shallow underground world with a burrowing soft robot

We've seen robots take to the air, dive beneath the waves and perform all sorts of maneuvers on land. Now, researchers are exploring a new frontier: the ground beneath our feet. Taking their cues from plants and animals that have evolved to navigate subterranean spaces, they've developed a fast, controllable soft robot that can burrow through sand.

MPs vote 461 to 60 in favour of extending social restrictions in England to 19 July – as it happened

How a supermassive black hole originates

How do supermassive black holes in the early universe originate? A team led by a theoretical physicist has come up with an explanation: a massive seed black hole that the collapse of a dark matter halo could produce.

Genetically engineered nanoparticle delivers dexamethasone directly to inflamed lungs

Nanoengineers have developed immune cell-mimicking nanoparticles that target inflammation in the lungs and deliver drugs directly where they're needed. As a proof of concept, the researchers filled the nanoparticles with the drug dexamethasone and administered them to mice with inflamed lung tissue. Inflammation was completely treated in mice given the nanoparticles, at a drug concentration where...

Inducing and tuning spin interactions in layered material

Magnetic-spin interactions that allow spin-manipulation by electrical control allow potential applications in energy-efficient spintronic devices. Researchers now describe the induction of such interactions in a layered material tantalum-sulfide by addition of iron atoms, and tuning by insertion of protons.
