• Human activities have an intense impact on Earth's deep subsurface fluid flow April 24, 2024
  Hydrologists predict human-induced underground fluid fluxes to rise with climate change mitigation strategies like carbon sequestration.
• Holographic displays offer a glimpse into an immersive future April 24, 2024
  Researchers have invented a new optical element that brings us one step closer to mixing the real and virtual worlds in an ordinary pair of eyeglasses using high-definition 3D holographic images.
• This salt battery harvests osmotic energy where the river meets the sea April 24, 2024
  Estuaries -- where freshwater rivers meet the salty sea -- are great locations for birdwatching and kayaking. In these areas, waters containing different salt concentrations mix and may be sources of sustainable, 'blue' osmotic energy. Researchers report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new […]
• Making diamonds at ambient pressure April 24, 2024
  Researchers have grown diamonds under conditions of 1 atmosphere pressure and at 1025 degrees Celsius using a liquid metal alloy composed of gallium, iron, nickel, and silicon, thus breaking the existing paradigm. The discovery of this new growth method opens many possibilities for further basic science studies and for scaling up the growth of diamonds […]
• Eruption of mega-magnetic star lights up nearby galaxy April 24, 2024
  While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays -- high-energy photons -- coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none. An international team realized that the burst must have been an […]
