The fact that we don’t see anything out there means that if they did exist, they vanished long ago and their signatures have decayed away.
A new type of gel, developed by chemists at the Martin Luther University Halle-Wittenberg (MLU), could help to make lithium-ion batteries safer and more powerful. The gel is designed to prevent the highly flammable electrolyte fluid from leaking.
Pillar-studded surface just hundreds of nanometres thick allows researchers to control direction, polarization and phase of thermal radiation.
Ever wonder why humans shrink as they age? Here’s everything you need to know to help you understand this strange phenomenon.

A landslide and its resulting megatsunami in a Greenland fjord in September 2023 were significant enough to send waves around the channel of water for an entire week, newly analyzed data collected from seismic monitors has shown.
In what’s known as a seiche, a number of smaller oscillations bouncing between shores combined to form standing waves in the partially enclosed body of water. The phenomenon was logged from signals that traveled as far as 5,000 kilometers (3,107 miles) around the globe.
The team behind the new research, from the GFZ German Research Center for Geosciences and the University of Potsdam in Germany, says this kind of sensing technology is an important part of monitoring remote areas such as Greenland.
For nearly 60 million years, our home planet was likely frozen into a big snowball.
Now, scientists have discovered evidence of Earth’s transition from a tropical underwater world, writhing with photosynthetic bacteria, to a frozen wasteland – all preserved within the layers of giant rocks in a chain of Scottish and Irish islands.
The team, led by researchers from University College London (UCL), examined more than 2,000 grains of zircon from 11 sandstone samples, taken from up to 200 meters within the 1.1 km-thick (0.7 miles) Port Askaig formation, and the older, underlying Garbh Eileach formation, which is 70 meters thick.
A study, published in the journal Science Bulletin and led by Dr. Haiping Hu from the Institute of Physics, Chinese Academy of Sciences (IOP, CAS), explores the non-Hermitian skin effect (NHSE) and non-Bloch bands.
Recently, an inelastic neutron scattering work on the bilayer nickelate La3Ni2O7-δ polycrystal finished by a team from Sun Yat-sen University was published in Science Bulletin. The team employed neutron spectroscopy to study the magnetic ground state and spin dynamics of La3Ni2O7-δ at ambient pressure.
