University of Melbourne researchers are leading a new push to address the growing harm of antimicrobial resistance (AMR) as more humans and animals become seriously ill or die from infections that medicine once treated easily.

Over-use and misuse of microbe-killing drugs – including antibiotics, antivirals and antifungals – is the main driver accelerating the evolution of resistance to these drugs in bacteria, viruses, fungi and parasites around the world.

The World Health Organisation calls AMR a top global public health threat that was directly responsible for 1.27 million deaths and contributed to 4.95 million deaths in 2019.

Physicists have theorized the existence of new types of celestial objects that they name “nestars.”

These are gravitational condensate stars, or gravastars, nestled among other gravitational condensate stars, like a Russian matryoshka doll, or nesting doll.

This type of doll is distinguished by its hollow, round form and the ability to be split apart to reveal a sequence of increasingly smaller dolls nestled inside.

Some of the oddest cosmic phenomena are short but tremendously powerful bursts of radio waves, which, in a fraction of a second, can give off as much energy as the sun does in a year. Known as fast radio bursts, these incredibly bright flashes of energy are thought to be related to dying stars called magnetars. Now, using two separate telescopes, astronomers have observed one of these events just a few minutes before and after it occurred, giving the best look yet at what causes these strange events.

Astronomers used NASA’s NICER (Neutron Star Interior Composition Explorer) on the International Space Station and NuSTAR (Nuclear Spectroscopic Telescope Array) in low-Earth orbit to observe a magnetar called SGR 1935+2154. Magnetars are a type of neutron star, the dense core left behind after a star collapses and with an extremely strong magnetic field. In October 2022, this magnetar gave off one of these strange, fast radio bursts.

AI processors need to get faster, says Jim Keller.

The H3’s main missions are to secure independent access to space and be competitive as international demand for satellite launches grows. “We made a big first step today toward achieving that goal,” Yamakawa said.

The launch is a boost for Japan’s space program following a recent streak of successes, including a historic precision touchdown on the moon of an unmanned spacecraft last month.

The liftoff was closely watched as a test for Japan’s space development after H3, in its debut flight last March, failed to ignite the second-stage engine. JAXA and its main contractor Mitsubishi Heavy Industries have been developing H3 as a successor to its current mainstay, H-2A, which is set to retire after two more flights.

A study in mice and nematodes has investigated a potential new therapeutic approach that could help people with the genetic variant that predisposes them to Alzheimer’s disease.

Authorities in Virginia are investigating the cause of a house explosion and fire that killed one firefighter, injured 10 others and leveled a home in a Washington, D.C., suburb.

A recent analysis reveals a newly identified species was lurking in plain sight.
