Discrimination, crime and suicidal thoughts associated with greater odds of firearm ownership among Black adults
Patients with a type of liver cancer known as hepatocellular carcinoma (HCC) often face an anxious wait after their tumor is removed. In up to half of these people, the cancer will return within 2 years after surgery or a treatment that destroys their tumors with heat. Researchers haven’t identified any therapies that can stop it from coming back.
That could change thanks to a...
Centaurus A captured in colorful detail by trio of telescopes
Black adults—particularly Black women—with higher levels of education and experiences of discrimination and crime are more likely to own a firearm, according to a study by the New Jersey Gun Violence Research Center at Rutgers.

How government guarantees give banking customers peace of mind and keep banks open
Centaurus A (Cen A), located some 12 million light-years away in the constellation Centaurus the Centaur, is the fifth-brightest galaxy in the night sky and hosts an exceptionally powerful supermassive black hole at its core. This oddly shaped galaxy was the latest target of two of NASA’s orbiting X-ray telescopes, the Chandra X-ray Observatory andContinue reading "Centaurus A captured in...
Video: What is meat?
Spooked by volatile reports from the Silicon Valley Bank in early March, many customers panicked and withdrew their money, creating the largest bank failure since the 2007-2008 financial crisis. The problem—investors and customers lost confidence in the bank, proving the perception of a bank's reliability can significantly impact its success.
Researchers devise a simpler way to mimic aspects of human vision
Beyond "burgers." Impossible "meat." A huge meatball (supposedly) made from wooly mammoth DNA.
Sanctions against Russians twice as effective since Ukraine invasion, finds study
Mimicking the performance of the human visual system is viewed as a difficult endeavor because of the extremely complex optical elements involved. In new work, researchers show that it's possible to create a lens system that reproduces certain characteristics of human eyesight using simple spherical optical components.
Are college students with religious tattoos more religious? Yes and no
Sanctions targeting Russian government officials have been significantly more effective at barring those individuals from the global financial system since the invasion of Ukraine, according to a study from researchers at The University of Texas at Austin.
NASA's Lunar Flashlight to fly by Earth
For most of U.S. history, tattoos have been associated with sailors and bikers, but not church-going people. As tattoos have become more popular, with nearly one-third of U.S. adults sporting at least one tattoo, religious-themed tattoos have also increased. A recent study examined the behaviors of college students with tattoos, including religious tattoos.
After outcry, disgraced sexual harasser removed from astronomy manuscript
NASA's Lunar Flashlight mission to the moon has ended, but the briefcase-size spacecraft will soon fly past Earth before heading into deep space. On Tuesday, May 16, at 9:44 p.m. PDT (Wednesday, May 17, at 12:44 a.m. EDT), the CubeSat will pass about 40,000 miles (65,000 kilometers) from our planet's surface.
BlackGEM telescopes begin hunt for gravitational-wave sources at ESO's La Silla Observatory
Within 2 weeks after a preprint was posted to arXiv on 31 March, outrage erupted on Twitter and multiple co-authors requested their names be removed. The issue wasn’t the science,
which focused on the detection of exoplanets
, but its authorship. To the dismay of many astronomers, Geoff Marcy was listed as the third of 16 authors.
Marcy was once a prominent...
Dual-radical observation in a photoswitchable coordination polymer with synergy effect of semi-conductivity
The BlackGEM array, consisting of three new telescopes located at ESO's La Silla Observatory, has begun operations. The telescopes will scan the southern sky to hunt down the cosmic events that produce gravitational waves, such as the mergers of neutron stars and black holes.
Report: Butterflies across the EU are in decline
In a study published in the journal National Science Review and led by Dr. Zhao-Yang Li (School of Material Science and Engineering, Nankai University) and Prof. Masahiro Yamashita (Department of Chemistry, Graduate School of Science, Tohoku University), a photoisomerizable ligand was used to synthesize two VT coordination polymers, which display VT and photoconversion behavior.
A predatory dinosaur from Brazil and its surprising anatomy
The diagnosis sounds worrying: More than 80% of habitats in the EU are currently considered vulnerable. This has negative consequences on their functional capability and thus the services they provide for humans. In order to counter this, the European Commission has proposed a new set of rules.
Designing 3D-printed pills with desired drug release
Irritator challengeri was a two-legged, meat-eating dinosaur, or more precisely—a spinosaurid. The knowledge of the species is based on the most complete fossil skull known from this group. With the aid of X-ray computed tomographs usually used in the context of medicine or material science, paleontologists from Greifswald, Munich (both Germany), Alkmaar (Netherlands) and Fribourg (Switzerland)...
High efficiency, salt resistance and high strength desalination achieved with new hydrogel solar evaporator
Don't be surprised to see pills with unusual shapes in the future. At first sight they may look funny, but they can release pharmaceuticals inside the body in a controlled manner. Using a combination of advanced computational methods and 3D printing, objects can be produced that dissolve in liquids in a predetermined format.
Bronze Age long-distance connections: Baltic amber in Aššur
In the face of increasing global scarcity of freshwater resources, desalination is considered one of the most effective ways to alleviate this problem. However, it does come with a catch—efficient and low-cost evaporation materials are key to achieving large-scale applications.
Creating kitty litter from soy waste
In 1914, two beads were found under the great ziggurat of Aššur in Iraq, in a foundation deposit dating from around 1800-1750 BC. Their material has now been identified as amber using Fourier Transform Infrared Spectroscopy (FT-IR). The beads represent some of the earliest amber specimens in southwest Asia and also some of the most distant discoveries from the find areas in the Baltic region.
New study suggests massive Joro spiders are gentle giants
Scientists with the Agricultural Research Service (ARS) are building a better mouse trap when it comes to cat litter. And in the process, they hope to kill two birds with one stone.
Timing is everything: New insights into floral development unveil nature's perfect clock
Despite their intimidating appearance, the giant yellow and blue-black spiders spreading across the Southeastern U.S. owe their survival to a surprising trait: They're rather timid.
Apochromatic X-ray focusing
The intricate process of flower development has long fascinated scientists seeking to unravel the mysteries behind nature's precision timing. In a study published in the journal The Plant Cell, a research team led by Nara Institute of Science and Technology (NAIST), Japan has shed light on the inner workings of floral meristem termination and stamen development, uncovering a unique mechanism...
New strategy identified to curb a fungal infection affecting more than 150 crops
A team of scientists from the Paul Scherrer Institut, the University of Basel and DESY have demonstrated the first-ever realization of apochromatic X-ray focusing using a tailored combination of a refractive lens and a Fresnel zone plate. This innovative approach enables the correction of the chromatic aberration suffered by both refractive and diffractive lenses over a wide range of X-ray...
How kids in some disadvantaged schools improved their results during COVID
Tomatoes, bananas, cabbages, melons, pumpkins and cucumbers… are just some of the 150 crops of commercial interest that are victims of Fusarium oxysporum, one of the most important pathogens in the world due to the millions of dollars in losses it is responsible for and its ability to attack different types of plants. Although it can go unnoticed in the soil for more than 30 years, when it...
Students from schools in low-income communities did not suffer significant "learning loss" during the pandemic years of 2020-2021, but instead improved in certain areas of study.
