Study suggests gun-free zones do not attract mass shootings
2024-09-03
Gun-free zones have often been blamed for making schools, malls and other public areas more attractive to shooters; however, there have been no quantitative studies examining those claims. Now, in a first of its kind study published in The Lancet Regional Health Americas, researchers at UC Davis Health and other institutions have shown that gun-free zones may, in fact, reduce the risk of mass shootings.
"Our most significant finding is that gun-free zones don't attract active shooters,” said the study’s first author, Paul Reeping, ...
Mathematicians model a puzzling breakdown in cooperative behaviour
2024-09-03
Darwin was puzzled by cooperation in nature—it ran directly against natural selection and the notion of survival of the fittest. But over the past decades, evolutionary mathematicians have used game theory to better understand why mutual cooperation persists when evolution should favour self-serving cheaters.
At a basic level, cooperation flourishes when the costs to cooperation are low or the benefits large. When cooperation becomes too costly, it disappears—at least in the realm of pure mathematics. ...

$1.8 million NIH grant to FAU engineering fuels quest to decode human evolution
2024-09-03
Natural selection is an important evolutionary force that enables humans to adapt to new environments and fight disease-causing pathogens. However, the unique footprints of natural selection in our genome can be buried beneath those left by other evolutionary forces. Thus, by leveraging information about multiple evolutionary forces, researchers can identify signatures of natural selection in the human genome, and ultimately determine its role in human adaptation and disease.
Low-cost DNA sequencing has ...
Communication helps parent relationships with new college students but has limits
2024-09-03
PULLMAN, Wash. -- When young adults first go off to college, more communication with parents generally leads to better relationships, but parents should avoid always initiating it, according to a study led by Washington State University researchers.
In a paper published in the journal Emerging Adulthood, WSU Assistant Professor Jennifer Duckworth and co-authors found that phone, text, video or in-person communication made first-year students feel better about the relationship with their parents. Students also felt better about the relationship when parents offered support or advice, and when they discussed important topics, such as studying and friendships. However, researchers found ...
Natural selection may create inter-species exploitation
2024-09-03
A modeling study suggests that one-sided interspecies cooperation can spontaneously emerge and persist over time, despite only one species benefitting. Evolutionary game theory, and the prisoner’s dilemma in particular, are often used to model the evolution of cooperation within a single species. In the prisoner’s dilemma, both parties benefit by cooperating, but the greatest benefit is earned by a defector who plays with a cooperator. The temptation to cheat tends to push players towards defection, ...
Targeted cancer therapies: Getting radioactive atoms to accumulate in tumors
2024-09-03
Prostate cancer is the second most common cancer among men worldwide, following lung cancer. In the United States alone, nearly 300,000 new cases are diagnosed annually. While reducing testosterone and other male hormones can be an effective treatment for prostate cancer, this approach becomes ineffective once the disease progresses to metastatic castration-resistant prostate cancer (mCRPC). At this stage, the cancer advances quickly and becomes resistant to conventional hormonal therapies and chemotherapy.
A clever strategy for fighting mCRPC is to exploit the ...
Gigantic asteroid impact shifted the axis of Solar System's biggest moon
2024-09-03
Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a Kobe University researcher realized that the Solar System's biggest moon's axis has shifted as a result of the impact, which confirmed that the asteroid was around 20 times larger than the one that ended the age of the dinosaurs on Earth, and caused one of the biggest impacts with clear traces in the Solar System.
Ganymede is the largest moon in the Solar System, bigger even than the planet Mercury, and is also interesting for the liquid water oceans beneath its icy surface. Like the Earth’s moon, it is tidally locked, meaning that it always shows the ...

False-positive mammograms discourage some women from future screenings
2024-09-02
Early detection of breast cancer through mammography screening continues to save lives. However, abnormal findings on mammograms can lead to women being recalled for additional imaging and biopsies, many of which turn out to be “false positives,” meaning they do not result in a cancer diagnosis. False positives can also have financial implications for patients and cause significant emotional anxiety.
A major, new study led by the UC Davis Comprehensive Cancer Center has found that women who received a false-positive result that required additional imaging or biopsy were less likely to return ...
The nervous system’s matchmaker
2024-09-02
When you ask a rideshare app to find you a car, the company’s computers get to work. They know you want to reach your destination quickly. They know you’re not the only user who needs a ride. And they know drivers want to minimize idle time by picking up someone nearby. The computer’s job, says Cold Spring Harbor Laboratory Associate Professor Saket Navlakha, is to pair drivers with riders in a way that maximizes everyone’s happiness.
Computer scientists like Navlakha call this bipartite matching. It’s the same task handled by systems pairing organ donors with transplant candidates, medical students with residency ...
Open Wide: Human Mouth Bacteria Reproduce through Rare Form of Cell Division
2024-09-02
By Emily Greenhalgh
One of the most diverse ecosystems on the planet is closer than you think — right inside your mouth. Your mouth is a thriving ecosystem of more than 500 different species of bacteria living in distinct, structured communities called biofilms. Nearly all of these bacteria grow by splitting [or dividing] into two, with one mother cell giving rise to two daughter cells.
New research from the Marine Biological Laboratory (MBL) and ADA Forsyth uncovered an extraordinary mechanism of cell division in Corynebacterium matruchotii, one of the most common bacteria living in dental plaque. ...
