Worcester Polytechnic Institute (WPI) researchers in the lab. Worcester Polytechnic Institute (WPI)Scientists in the US have been awarded $6.3 million to convert scrap metal into high-performance parts using artificial intelligence (AI) and advanced 3D printing, as part of an ambitious project that could potentially transform additive manufacturing.
Two-million-year-old teeth yield oldest African human genetic data

1 day ago | interestingengineering.com | Mrigakshi Dixit

A new scientific study is uncovering unprecedented details about the lives and genetics of extinct human relatives. An international team of researchers has determined the biological sex of an individual who lived two million years ago for the first time. They studied four fossil teeth unearthed in the renowned Swartkrans cave in South Africa. These teeth belonged to an ape-like prehistoric human – the enigmatic Paranthropus robustus.
Low-grade clay turned into powerful cement for green construction

1 day ago | interestingengineering.com | Mrigakshi Dixit

Now, new research from RMIT University in Australia has unlocked the potential of low-grade illite clay, a cheaper and far more abundant alternative. A key insight is that this illite clay, when blended with low-grade kaolinite, can yield stronger concrete. A large chunk of cement’s CO₂ emissions result from a chemical reaction where limestone (CaCO₃) is heated in a kiln, breaking down into lime (CaO) and releasing CO₂. This process is an unavoidable step in creating cement clinker.

Stratolaunch's Roc aircraft carrying Talon-A2. StratolaunchStratolaunch has successfully performed two reusable test flights of its Talon-A2 drone. The tests take the company a step closer to achieving its goal of launching operational hypersonic weapons tests. Stratolaunch is backed by the US Department of Defense’s (DoD) Multi-Service Advanced Capability Hypersonic Testbed (MACH-TB) program.
Powerful US supercomputer measures pressure inside neutron star

2 days ago | interestingengineering.com | Mrigakshi Dixit

Neutron stars are formed from the cataclysmic collapse and subsequent explosion of massive stars. They are among the universe’s most extreme and enigmatic cosmic laboratories, offering unique insights into the fundamental forces of nature. Neutron stars are incredibly difficult to decipher. Experts can’t recreate their extreme conditions in a lab, and the closest one is 400 light-years away – too distant for detailed telescopic observation. So, how do astrophysicists peer into these cosmic enigmas?
