An international team of researchers from Austria and the UK has shown that Goffin’s cockatoos (Cacatua goffiniana) can manufacture and use stick-type tools of appropriate shape and length out of three different materials, suggesting that the birds can anticipate how the tools will be used. Goffin’s cockatoos can cut out …

Scientists have discovered a new type of photoreceptor protein that is about 50 times more efficient at capturing light than the rhodopsin, a protein that resides in cell membranes in the retina of the human eye.

DNA makes up only half of the material inside chromosomes, according to a new study published in the journal Molecular Cell. Up to 47% of their structure is a mysterious sheath that surrounds the genetic material. Booth et al. develop a microscopy method called 3D-CLEM. Using this approach, they find …

New research confirms that the hen harrier (Circus cyaneus), a medium-sized bird of prey found in parts of North America and Eurasia, is two different species of bird that are only distantly related.

Bathochordaeus charon — an extremely rare species of giant larvacean — has been rediscovered, more than a century after the only previous known specimens of the species were found. Bathochordaeus charon and its ‘house’ in Monterey Bay: giant larvaceans use their oikoplastic cells to secrete complex filters or ‘houses’ that …

According to a team of researchers led by Gerald Wright, a professor of biochemistry and biomedical sciences at McMaster University, Lechuguilla Cave — an underground ecosystem that has been isolated from the surface for over 4 million years — is home to a remarkable prevalence of antibiotic-resistant bacteria. Lechuguilla Cave, …

Through new experiments involving the Schrödinger’s cat state paradox, physicists at Yale University have shown that the famous cat can be in two separate locations at the same time. Chen Wang and co-authors have given Schrödinger’s cat a second box to play in. Image credit: Michael S. Helfenbein / Yale …

Nihonium (Nh), moscovium (Mc), tennessine (Ts) and oganesson (Og) are the new names of chemical elements 113, 115, 117 and 118 on the periodic table. Periodic table of the elements.

An international team of scientists has identified a second gravitational wave event in the data from the twin detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO). This image depicts two black holes just moments before they collided and merged with each other, releasing energy in the form of gravitational waves. …

On the surface of giant gaseous planets, hydrogen is a gas. But between this gaseous layer and the liquid metal hydrogen in the planet’s core lies a layer of dark hydrogen, says a team of physicists led by Dr. Alexander Goncharov from Carnegie Institution of Washington and University of Edinburgh …
