Poor sleep could lead to between two and seven years worth of heightened heart disease risk and even premature death, according to a new study led by researchers at the University of Sydney in collaboration with Southern Denmark University.

The study analyzed data from more than 300,000 middle-aged adults from the UK Biobank and found that different disturbances to sleep are associated with different durations of compromised later in life compared to healthy sleepers.

In particular, men with clinical sleep-related breathing disorders lost nearly seven years of cardiovascular disease-free life compared to those without these conditions, and women lost over seven years. Importantly, even general , such as insufficient sleep, insomnia complaints, snoring, going to bed late, and is associated with a loss of around two years of normal heart health in men and women.

On Thursday, March 2 at 12:34 a.m. ET (12:34 UTC), Falcon 9 launched Dragon’s sixth operational human spaceflight mission (Crew-6) to the International Space Station from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. Following stage separation, Falcon 9’s first stage landed on the Just Read the Instructions droneship.

Dragon will autonomously dock with the space station on Friday, March 3 at approximately 12:43 a.m. ET (5:43 UTC). Follow Dragon and the crew’s flight below.

During their time on the orbiting laboratory, the crew will conduct over 200 science experiments and technology demonstrations in areas such as life and physical sciences to advanced materials, technology development, in-space production applications, and even student-led research.

Imagine a sheet of material just one layer of atoms thick—less than a millionth of a millimeter. While this may sound fantastical, such a material exists: it is called graphene and it is made from carbon atoms in a honeycomb arrangement. First synthesized in 2004 and then soon hailed as a substance with wondrous characteristics, scientists are still working on understanding it.

Postdoc Areg Ghazaryan and Professor Maksym Serbyn at the Institute of Science and Technology Austria (ISTA) together with colleagues Dr. Tobias Holder and Professor Erez Berg from the Weizmann Institute of Science in Israel have been studying for years and have now published their newest findings on its superconducting properties in a research paper in the journal Physical Review B.

“Multilayered graphene has many promising qualities ranging from widely tunable band structure and special optical properties to new forms of superconductivity—meaning being able to conduct electrical current without resistance,” Ghazaryan explains.
