'Ultramassive black hole' one of the largest ever found
31 March, 2023Astronomers have discovered one of the biggest black holes ever found — over 30 billion times the mass of the Sun — by taking advantage of gravitational lensing.
Non-invasive stress tests trialled in koala joeys
30 March, 2023Instead of having to take blood, the test enables a joey's stress levels to be measured through samples of their faecal droppings.
Astronomers observe 'brightest ever' gamma-ray burst
29 March, 2023Astronomers have claimed that the explosion is the brightest burst of X-ray and gamma-ray energies since human civilisation began.
Project proves existence of dark matter surrounding black holes
28 March, 2023Researchers found that dark matter around black holes can generate significant dynamical friction, slowing down the orbital speed of companion stars in binary systems.
Possible biomarkers discovered for epilepsy
22 March, 2023Researchers have discovered higher levels of immune proteins in the blood before and after an epileptic seizure, which could result in better diagnostic methods.
Air pollution studies suggest that almost nowhere on Earth is safe
17 March, 2023Researchers have found that only a tiny portion of the global population is exposed to levels of PM2.5 below those recommended by the WHO, resulting in risks to our health.
Solvent enables efficient gas separation, carbon capture
15 March, 2023Researchers have developed 'porous liquids' that are able to dissolve very large amounts of gas and can selectively dissolve one gas from a gas mixture.
Newly discovered enzyme converts air into electricity
10 March, 2023Scientists have discovered an enzyme that converts air into energy, using the low amounts of the hydrogen in the atmosphere to create an electrical current.
Dipstick test to screen for bat-borne virus
08 March, 2023Researchers have developed a simple dipstick test to screen for a highly infectious, potentially deadly virus transmitted by bats to humans and pigs in Asia.
Plastics upcycling with a zirconia-based catalyst
07 March, 2023US researchers have developed a new type of catalyst, made only of earth-abundant materials, to break down polyolefin plastics into new, useful products.
Blood biomarker could help in diagnosing vascular dementia
03 March, 2023Measuring a key blood molecule may help doctors diagnose whether or how much impaired blood flow to a patient's brain is contributing to dementia or cognitive problems.
From sea water to hydrogen — no desalination required
27 February, 2023A new method to produce hydrogen straight from sea water is said to be simple, scalable and far more cost-effective than any green hydrogen approach currently in the market.
James Webb telescope finds galaxies "too big to even exist"
23 February, 2023Researchers used the telescope to observe massive candidate galaxies at the beginning of time, believed to be up to 100 billion times the mass of the Sun.
Earth's structure found to have a distinct 'fifth layer'
22 February, 2023Seismologists believe they have documented evidence of a distinct layer inside Earth — a solid 'metallic ball' that sits within the centre of the inner core.
Needle-free malaria detection with a light beam
08 February, 2023A beam of harmless infrared light is shone on a person's ear or finger for 5–10 seconds, collecting an infrared signature that is processed by a computer algorithm.
