Phys.org / Space debris poses growing threat, but new study suggests cleanup is feasible
High up in Earth's orbit, millions of human-made objects large and small are flying at speeds of over 15,000 miles per hour. The objects, which range from inactive satellites to fragments of equipment resulting from explosions ...
Phys.org / KIC 5623923 is a faint eclipsing binary exhibiting Delta Scuti-type pulsations, observations find
Using NASA's Kepler space telescope, Chinese astronomers have observed a binary star system known as KIC 5623923. As a result, they found that the investigated system is a faint eclipsing binary experiencing Delta Scuti-type ...
Phys.org / Fearless frogs feast on deadly hornets
A remarkable resistance to venom has been discovered in a frog that feasts on hornets despite their deadly stingers. This frog could potentially serve as a model organism for studies on mechanisms underlying venom tolerance.
Phys.org / New study challenges the idea of humans as innately nature-loving
Nature is a source of well-being and recovery for many people. However, research shows that there is also a growing number of individuals who experience negative emotions, such as fear, discomfort, or even disgust, toward ...
Phys.org / Nanotyrannus was not a juvenile T. rex, new study confirms
For decades, paleontologists argued over the lone skull used to establish the distinct species Nanotyrannus. Was it truly a separate species or simply a juvenile Tyrannosaurus rex? A new paper published in Science has definitively ...
Phys.org / Close brush with two hot stars millions of years ago left a mark just beyond our solar system
Nearly 4.5 million years ago, two large, hot stars brushed tantalizingly close to Earth's sun. They left behind a trace in the clouds of gas and dust that swirl just beyond our solar system—almost like the scent of perfume ...
Phys.org / Lightning channels reveal hidden bursts: Lateral negative re-discharges observed for first time
A new study led by researchers from the Institute of Atmospheric Physics of the Chinese Academy of Sciences (CAS) has uncovered the first observational evidence of lateral negative re-discharges occurring on negative leader ...
Medical Xpress / Childhood instability accelerates women's sexual strategies, study suggests
California State University, Sacramento, researchers traced how disordered childhood social worlds in women connected to faster life history traits and greater mating effort, with those traits explaining 22.2% of the association ...
Phys.org / Sugars, 'gum,' stardust found in NASA's asteroid Bennu samples
The asteroid Bennu continues to provide new clues to scientists' biggest questions about the formation of the early solar system and the origins of life. As part of the ongoing study of pristine samples delivered to Earth ...
Tech Xplore / Laser-assisted 3D printing can fabricate free-standing thermoset-based electronics in seconds
Thermosets, such as epoxy and silicon rubbers, are a class of polymer (i.e., plastic) materials that harden permanently when they undergo a specific chemical reaction, known as "crosslinking." These materials are highly durable, ...
Phys.org / Probing the quantum nature of black holes through entropy
In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of thermodynamics, which states that entropy remains positive and vanishes at extremely low temperatures, ...
Medical Xpress / New approach makes common breast cancer type responsive to immunotherapy
A study led by researchers at the Hospital del Mar Research Institute advances one of the most significant milestones in breast cancer treatment, making immunotherapy effective against the most common tumor type, estrogen ...
