We propose and demonstrate the first chip-based 3D printer, consisting of a silicon-photonics chip that emits non-mechanically-reconfigurable beams into photocurable resin, enabling future compact, portable, and low-cost next-generation 3D printers.
Most collapsed stars fully rotate in seconds. This one takes almost an hour.
Australian scientists from the University of Sydney and Australia’s national science agency, CSIRO, have detected what is likely a neutron star spinning slower than any other ever measured.
No other radio-emitting neutron star, out of the more than 3,000 discovered so far, has been discovered rotating so slowly. The results are published today (June 5) in Nature Astronomy.

The authors show that dipolar condensates are prevalent in bosonic systems due to a self-proximity effect. Furthermore, they propose a new type of Josephson effect called dipolar Josephson effect, where a supercurrent of dipoles happens in the absence of particle flow.
How often should patients be screened for cannabis use? This is what a recent study published in JAMA Network Open hopes to address as a team of researchers from the University of California, Los Angeles (UCLA) investigated how primary care patients who recognize themselves as recreational cannabis users could potentially be at risk for—or suffering from—cannabis use disorder. This study holds the potential to raise awareness about healthcare providers conducting cannabis screening that could help identify early signs of cannabis use disorder in primary care patients.
For the study, the researchers analyzed surveys completed by 175,734 patients prior to a primary care appointment to assess their cannabis use and was conducted between January 2021 and March 2023. In the end, the researchers found that 17 percent indicated cannabis use in their surveys, of which 34.7 percent of those individuals demonstrated potentially high risk for cannabis use disorder based on their survey results. Additionally, 76.1 percent of patients indicated they used cannabis for medical reasons while not identifying as medical cannabis users. The researchers note these results indicate steps should be taken to conduct routine cannabis screenings of primary care patents by healthcare professionals.
“Patients may not tell their primary care providers about their cannabis use, and their doctors may not ask about it,” said Dr. Lillian Gelberg, MD, who is Professor in the Department of Family Medicine at the UCLA David Geffen School of Medicine and lead author of the study. “Not asking patients about their cannabis use results in a missed opportunity for opening up doctor-patient communication regarding use of cannabis generally and for management of their symptoms. ”
