Why did humans evolve without tails? Though humans’ ape ancestors have tails, we evolved without them due to a single gene mutation, which was pinpointed through researching the genomes of six ape species and 15 monkey species. Scientists are unsure whether becoming tailless was an evolutionary benefit or a chance mutation, but one theory is […]

Modern technologies enable the design and nanofabrication of photonic devices for manipulation of optical fields on spatial scales much smaller than the wavelength of light. In particular, the resonant coupling of photons with collective electronic excitations in metals and two-dimensional materials, i.e., plasmons, can be used to engineer strongly enhanced near fields confined to the […]
Just over five years ago, on 22 February 2019, an unmanned space probe was placed in orbit around the Moon. Named Beresheet and built by SpaceIL and Israel Aerospace Industries, it was intended to be the first private spacecraft to perform a soft landing. Among the probe’s payload were tardigrades, renowned for their ability to […]
A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, provides the first direct evidence of the imprint left by what may be the universe’s most powerful magnetic fields on “deconfined” nuclear matter . The evidence comes from […]
Roundworms are the most commonly used animal model to investigate aging and methods to increase the lifespan such as intermittent fasting. Latest research indicates that jumping genes could be another target for interventions aiming towards expanding the lifespan. What are jumping genes? Also called transposons, are movable stretches of DNA of possible viral origin that […]
Dinosaur species may have crossed sea to find Africa Fossils in Morocco reveal a previously unknown duckbill dinosaur species, Minqaria bata, which is anatomically similar enough to duckbill species found in Europe to suggest that the pony-size creatures swam or floated across the Tethys Sea and diversified quickly into at least three species in North […]
Progress in particle physics has traditionally been achieved by a symbiosis of experiments at the energy and intensity frontiers and model-building. This has led to the current situation of the Standard Model (SM) representing our best knowledge of particle physics, but which leaves a number of open questions to be resolved. These include the composition […]
Nitric oxide (NO) is a gas generated during industrial combustion and by vehicle engines that causes damage to the ozone layer and contributes to acid rain. In this regard, early studies on NO were focused on its nature as a pollutant agent. In most living organisms, NO is endogenously produced and possess a double face […]
Nuclear power is considered one of the ways to reduce dependence on fossil fuels, but how to deal with nuclear waste products is among the issues surrounding it. Radioactive waste products can be turned into more stable elements, but this process is not yet viable at scale. New research led by physicists from the University […]
One of the most recurrent (and most disputed) headers during the last half century in the debates about whether cosmology points to some ‘fundamental purpose’ of the universe is (I didn’t need to say it) the (ill-)famous anthropic principle . Many versions of it have been formulated since it was so named in the 70’s […]
