Limits on pot fishing can result in win-win for fishermen and marine wildlife

The first major study into the impact of inshore potting for crab and lobster within a Marine Protected Area has found that in areas of low potting intensity the industry is operating in a way that had little impact on seabed species or economically-important shellfish.

Higher iron levels may boost heart health -- but also increase risk of stroke

Scientists have helped unravel the protective -- and potentially harmful -- effect of iron in the body.

Rugby-style tackling may have lower force of impact than football-style tackling

The style of tackling used in rugby may be associated with a lower force of impact than the style used in football, according to a preliminary study of college athletes.

Insurance linked to hospitals' decision to transfer kids with mental health emergencies

A national study finds differences in the decisions to admit or transfer children with mental health emergencies based on the patients' insurance type. Children without insurance are more likely to be transferred to another hospital than those with insurance.

Salt regulation among saltmarsh sparrows evolved in 4 unique ways

A new study finds that different bird species in the same challenging environment -- the highly saline ecosystem of tidal marshes along ocean shores -- were able to evolve unique species-specific ways to address the same problem.

Novel therapy administered after TBI prevents brain damage

Could a therapy administered 30 minutes after a traumatic brain injury prevent damage that leads to seizures and other harmful effects? Researchers think so.

Researchers track how cats' weights change over time

Researchers have accessed data on more than 19 million cats and have learned that most cats continue to put on weight as they age.

Supernova observation first of its kind using NASA satellite

Researchers have published findings about a supernova observed using TESS, adding new insights to long-held theories about the elements left behind after a white dwarf star explodes into a supernova.

By cutting ozone pollution now, China could save 330,000 lives by 2050

If China takes strong measures to reduce its ozone pollution now, it could save hundreds of thousands of lives in the long run, according to a new study.

What to call someone who uses heroin?

A first-of-its-kind study has found that people entering treatment for heroin use most often called themselves 'addicts,' but preferred that others called them 'people who use drugs.'

Cancer device created to see if targeted chemotherapy is working

Researchers have created a device that can determine whether targeted chemotherapy drugs are working on individual cancer patients. The portable device, which uses artificial intelligence and biosensors, is up to 95.9% accurate in counting live cancer cells when they pass through electrodes, according to a new study.

Prescribed opioids associated with overdose risk for family members without prescriptions

Access to family members' drugs may be a strong risk factor for overdose in individuals without their own prescriptions, according to a new study.

Women's stronger immune response to flu vaccination diminishes with age

Women tend to have a greater immune response to a flu vaccination compared to men, but their advantage largely disappears as they age and their estrogen levels decline, suggests a new study.

Speeding up science on near-earth asteroids

Modeling the shape and movement of near-Earth asteroids is now up to 25 times faster thanks to new research.

Limitation exposed in promising quantum computing material

Physicists have theorized that a new type of material, called a three-dimensional (3-D) topological insulator (TI), could be a candidate to create qubits for quantum computing due to its special properties. A study found that when the TI's insulating layers are as thin as 16 quintuple atomic layers across, the top and bottom metallic surfaces begin to destroy their metallic properties.

Researchers wirelessly hack 'boss' gene, a step toward reprogramming the human genome

A new study describes how researchers wirelessly controlled FGFR1 -- a gene that plays a key role in how humans grow from embryos to adults -- in lab-grown brain tissue. The ability to manipulate the gene, the study's authors say, could lead to new cancer treatments, and ways to prevent and treat mental disorders such as schizophrenia.

Gaia starts mapping the galactic bar in the Milky Way

The first direct measurement of the bar-shaped collection of stars at the centre of our Milky Way galaxy has been made by combining data from the Gaia mission with complementary observations by ground- and space-based telescopes.

Why some greater sage grouse males 'strut' better than others

When it comes to mating displays, a little persistence can go a long way, at least for the greater sage grouse. Scientists have now used a custom-built statistical model to understand an underexplored dimension of greater sage grouse mating display behavior. The authors report that males that show greater display persistence, even in the face of seemingly uninterested females, have a competitive advantage over their peers.

Chaos theory produces map for predicting paths of particles emitted into the atmosphere

Floating air particles following disasters and other geological events can have a lasting impact on life on Earth, and a new model drawing on chaos theory looks to help predict how these particles move, with an eye toward applications for geoengineering. Scientists have developed a model for following particles as they travel around the globe. Using it, she has generated maps that can be used to predict how particles will be dispersed above the world.
