Engineers describe how fluid suspensions exhibit different behaviors at different scales
Honey is already a thick liquid, but let it begin to crystalize and it can become downright clumpy. The sugar crystals in suspension seem to increase its viscosity. This phenomenon occurs throughout the natural and constructed world: From mudflows to.....»»
How to cut stray cat numbers in a way that works better for everyone
Stray cats are a big problem across most Australian cities and towns. They cause many complaints related to nuisance behaviors and concerns about urban wildlife, as well as straining government resources. Ratepayers ultimately pay for the substantial.....»»
Report: Apple working on bringing Apple TV app to Android phones
Apple is finally bringing the Apple TV app to Android phones and tablets, as reported by Bloomberg. The company is in the process of hiring engineers to help lead the effort and build out the software. Previously, the company has made an app for the.....»»
New device precisely controls photon emission for more efficient portable screens
Recently, a team of chemists, mathematicians, physicists and nano-engineers at the University of Twente in the Netherlands developed a device to control the emission of photons with unprecedented precision. This technology could lead to more efficien.....»»
"Extraordinary" 4,000-year-old Egyptian skull may show signs of attempts to treat cancer
From ancient texts we know that—for their times—the ancient Egyptians were exceptionally skilled at medicine. For example, they could identify, describe, and treat diseases and traumatic injuries, build protheses, and put in dental fillings. Othe.....»»
New insights into juvenile crown-of-thorns starfish behaviors that threaten reefs
A new study by researchers from the University of Sydney provides new insights into the behavior of juvenile crown-of-thorns starfish (COTS), a significant contributor to coral reef devastation in the Indo-Pacific region. The research, published in P.....»»
NASA"s OSIRIS-APEX unscathed after searing pass of sun
Mission engineers were confident NASA's OSIRIS-APEX (Origins, Spectral Interpretation, Resource Identification—Apophis Explorer) spacecraft could weather its closest ever pass of the sun on Jan. 2, 2024. Their models had predicted that despite trav.....»»
Speeding up calculations that reveal how electrons interact in materials
Materials scientists and engineers would like to know precisely how electrons interact and move in new materials and how the devices made with them will behave. Will the electrical current flow easily within the material? Is there a temperature at wh.....»»
Does String Theory Actually Describe the World? AI May Be Able to Tell
Using machine learning, string theorists are finally showing how microscopic configurations of extra dimensions translate into sets of elementary particles—though not yet those of our universe......»»
Opinion: I want to keep my child safe from abuse—but research tells me I"m doing it wrong
Child sexual abuse is uncomfortable to think about, much less talk about. The idea of an adult engaging in sexual behaviors with a child feels sickening. It's easiest to believe that it rarely happens, and when it does, that it's only to children who.....»»
Scientists reveal elastic turbulence has more in common with classical Newtonian turbulence than expected
Blood, lymph fluid and other biological liquids can have surprising and sometimes troubling properties. Many of these biological solutions are non-Newtonian fluids, a type of liquid that is characterized by a non-linear relationship between stress an.....»»
Google’s “AI Overview” can give false, misleading, and dangerous answers
From glue-on-pizza recipes to recommending "blinker fluid," Google's AI sourcing needs work. Enlarge / This is fine. (credit: Getty Images) If you use Google regularly, you may have noticed the company's new AI Overviews.....»»
Droplets that swim toward dissolution could inspire fluid microbots
Researchers discovered that microscopic liquid droplets swim toward solvent conditions that favor their dissolution. This mechanism may underlie some transport processes within living cells, and could be exploited to develop fluid micro robots......»»
Artificial intelligence resolves conflicts impeding animal behavior research
Artificial intelligence software has been developed to rapidly analyze animal behavior so that behaviors can be more precisely linked to the activity of individual brain circuits and neurons, researchers in Seattle report......»»
Researchers describe spin-boson systems to configure quantum devices
Many of today's quantum devices rely on collections of qubits, also called spins. These quantum bits have only two energy levels, the "0" and the "1." However, spins in real devices also interact with light and vibrations known as bosons, greatly com.....»»
Fail2Ban: Ban hosts that cause multiple authentication errors
Fail2Ban is an open-source tool that monitors log files, such as /var/log/auth.log, and blocks IP addresses that exhibit repeated failed login attempts. It does this by updating system firewall rules to reject new connections from those IP addresses.....»»
Researchers propose use of electrical blackouts to determine impact of artificial light on wildlife
New research proposes the use of electrical blackouts, such as those experienced during loadshedding in South Africa, to enhance our understanding of how artificial light in urban areas may be affecting wildlife behaviors......»»
Study suggests less conformity leads to more innovation
Sociodiversity—the diversity of human opinions, ideas, and behaviors—is a driving force behind many positive developments......»»
Study unveils strategy for improving mechanical properties of aluminum composites
Particle-reinforced aluminum matrix composites (PRAMCs), in which the aluminum matrix is reinforced with nanoparticles, exhibit great potential for applications in the aerospace and automobile industries. These materials combine the advantages of bot.....»»
Study: Social networks can influence perception of climate-change risk
A new paper co-written by a University of Illinois Urbana-Champaign urban and environmental economics expert shows that social networks can play a significant role in influencing the financial behaviors and perception of catastrophic risks brought ab.....»»
New polystyrene recycling process could be world"s first to be both economical and energy-efficient
