Phys.org / Urokodia! 518-million-year-old fossil shows beginning of spider's bite
The earliest evidence of spiders' fangs has been identified in a 518-million-year-old fossil by scientists at the University of Leicester and Yunnan University.
Phys.org / Single-atom catalyst turns lignin into valuable chemicals with near-complete conversion
Researchers at The University of Manchester and Hebei University of Technology have identified how a new class of catalyst can break down lignin into useful chemical building blocks, offering a more sustainable route to replace ...
Phys.org / Reanalysis suggests 'Phoebe' is a variable star, not a primordial black hole
A new study debunks a recent claim that astronomers may have detected a lunar-mass primordial black hole. In a reanalysis of observations from the Dark Energy Camera (DECam), researchers found that the star nicknamed "Phoebe" ...
Phys.org / XMM-Newton and Chandra help revise distance to Milky Way's outer spiral arms
The European Space Agency's XMM-Newton and NASA's Chandra X-ray space telescopes have spotted the aftermath of three bright explosions echoing through the outer spiral arms of our galaxy, the Milky Way. By measuring the distance ...
Phys.org / Small-molecule switches put therapeutic CRISPR editing under on-demand control in living tissues
In a study published in Science Translational Medicine, a team of researchers led by Dr. Wang Yu from the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences developed PRINCE and Little Prince, dual ...
Phys.org / Spider venoms could stop deadly varroa mites killing honey bees
Spider venoms contain ingredients that could lead to a new treatment to protect honeybees from the deadly Varroa destructor mite, according to a study led by the University of the Sunshine Coast. Researchers identified components ...
Phys.org / Why nanoscale droplets don't coalesce and microscale droplets do
Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon ...
Phys.org / Last-minute launch problem delays satellite rescue mission for NASA
A rush rescue mission to save a NASA space telescope remains grounded, this time because of a last-minute launch problem.
Phys.org / Coral loss may erase up to $3 billion in Hawaiʻi reef recreation by 2100
Coral reef decline driven by climate change could cost Hawaiʻi residents between $1.8 billion and $3 billion in lost reef-related activities by 2100, according to a new study published in Ecological Economics. The research ...
Phys.org / Nearby 'Super Earth' may be a better candidate for life than previously thought
Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits ...
Phys.org / Plant DNA harbors virus 'fossils' that reflect 300 million years of evolution
Is it possible to study the history of viruses that emerged several hundred million years ago? An international team of INRAE and CIRAD researchers answered this question by exploring plant genomes to find the molecular fossils ...
Medical Xpress / Dual-mobility hip replacement implant can lower dislocation risk by 70%
A new type of hip replacement implant reduces the risk of joint dislocation after surgery by 70%, according to a new study involving 1,600 patients across 44 hospitals in Sweden and the UK, published in The Lancet. The new ...
