Quantum physicists succeed in controlling energy losses and shifts

Researchers at Aalto University have successfully controlled energy losses and shifts in a high-quality superconducting resonator, allowing for increased dissipation rate on demand. This breakthrough has significant implications for the development of larger-scale quantum computers and innovative quantum technological devices.

Remembering to forget

A human neuroimaging study suggests that intentionally redirecting attention away from an unwanted experience during memory formation and suppressing its retrieval once formed can facilitate forgetting. The research provides evidence for a new link between voluntary control of visual attention and long-term memory fate.

Fossil teeth from Kenya solve ancient monkey mystery

The discovery of fossilized monkey teeth in West Turkana, Kenya, fills a 6-million-year gap in Old World monkey evolution. The newly found teeth, belonging to the species Alophia metios, have primitive dentition, lacking 'lophs,' and are believed to be adapted to a diet of hard fruits, seeds, and nuts.

Research connects dots among ocean dynamics, drought and forests

A recent study by University of Wyoming researcher Bryan Shuman found connections between Atlantic Ocean changes, centuries-long droughts, and forest transformations over the past 8,000 years. The study's predictability framework helps anticipate future climate-driven weather and ecosystem shifts.

OHIO study: Information literacy can combat 'fake news'

A new study by Ohio University professor Dr. M. Laeeq Khan found that media and information literacy are key factors in recognizing misinformation on social media. The study suggests that individuals with strong information verification skills are less likely to share misinformation online.

Researchers report new light-activated micro pump

Researchers developed a laser-driven photoacoustic microfluidic pump that moves fluids in any direction without mechanical parts or electrical contacts. The device uses a plasmonic quartz plate implanted with gold atoms to generate an ultrasonic wave, driving the fluid via acoustic streaming.

Southern Ocean acidification puts marine organisms at risk

Researchers warn that acidification of the Southern Ocean will disrupt marine food webs due to a layer of corrosive water forming below the surface. The new shallow horizon would reduce viable pteropod habitat, impacting global fisheries and ocean ecosystems.

When coyote parents get used to humans, their offspring become bolder, too

Researchers observed coyote families at a Utah facility during breeding seasons and found that parental influence plays a major role in shaping their behavior. Coyotes become bolder when parents are more fearless, and this trait is passed on to their offspring, which can lead to negative interactions with humans.

Selfish genetic elements amplify inflammation and age-related diseases

Researchers from the University of Rochester discover that LINE1 retrotransposons become more active with age, triggering inflammation and age-related diseases. By understanding the impacts of these genomic parasites, scientists can develop strategies to inhibit them and combat aging.

How to train your robot (to feed you dinner)

Researchers at the University of Washington have created a robotic system that can strategize how to use a fork to pick up and deliver bites to a person's mouth. The robot used an object-detection algorithm and a new skewing-and-feeding strategy to successfully pick up hard foods but struggled with soft foods.

For hyenas, there's no 'I' in clan

In a new study, researchers found that female spotted hyenas who form strong coalitions with other females can overthrow their superiors and improve their fitness. The study revealed that these alliances play a crucial role in maintaining stable social hierarchies and improving the overall rank of coalition members.

Timing of precipitation pattern change

Researchers project timing and location of precipitation changes relevant to agricultural crop production due to climate change. Precipitation patterns are expected to increase in high latitudes like North America and Europe by 2020s or have already emerged in regions such as the Mediterranean.

New 'tracers' improve diagnosis of cancer and may be useful for treatment

Researchers have identified two new nuclear medicine tracers that provide high-contrast images for cancer diagnosis, allowing for shorter imaging times and no diet changes. The tracers target cancer-associated fibroblasts, promoting tumor growth, migration, and progression.
