For nearly a century, scientists have been puzzling over fossils from a strange and robust-looking distant relative of early humans: Paranthropus robustus. It walked upright, and was built for heavy chewing with relatively massive jaws, and huge teeth with thick dental enamel. It's thought to have lived between 2.25 million and 1.7 million years ago.
Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass prevents galaxies from falling apart. But we don't know what it is.
As companies face pressure to increase productivity, many are calling workers back to the office—even though there is limited evidence that return-to-office policies actually improve innovation or performance.
Authorities in the ACT have released draft regulations for the welfare of dogs. One inclusion getting attention is a guideline "requiring all dogs to have a minimum of three hours of human contact daily."
Even-aged forest management is geared towards timber production with ecosystem health as a lesser consideration. This creates a dichotomy where forests are treated either as plantations or reserves. Uneven-aged management can bring compromise to conflicting land uses by reducing ecosystem impacts while still allowing timber extraction. Whereas selection forestry focuses on which trees are taken, retention forestry focuses on protecting features that will remain after logging. These biological legacies provide ecosystem continuity.
Humans have long mastered the art of expressing their goals and needs through both language and gestures. A similar behavior is also observed in non-human primates, who use complex gestures to convey what they want, but does the use of deliberate gestures extend beyond primates to other members of the animal kingdom?
The number of states banning smartphones in schools is growing.
Well, it's July 12, which means (a) the Steam Summer Sale is over and (b) it's really hot outside in the northeastern U.S. This week, researchers discovered a cool new fish and named it after Darth Vader. An analysis of the DART mission suggests that while it proved that an impactor could alter the trajectory of an asteroid, it ejected boulders in unpredictable directions that could complicate other impactor missions. And archaeologists uncovered a rock art panel that could depict an elite individual from the First Dynasty.
Molecular glues, tiny molecules that connect one protein to another, are promising targets for pharmaceutical research. By linking a disease-related protein to one that triggers a cell's demolition and recycling pathways, pharmaceutical researchers have been able to develop novel therapies for otherwise drug-resistant diseases.
In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported a photopumped lasing from a buried dielectric photonic-crystal surface-emitting laser emitting at room temperature and an eye-safe wavelength. Their findings, published in IEEE Photonics Journal, improve upon current laser design and open new avenues for defense applications.
