High harmonic lasers unlock a resolution boost for optical microscopy

Physicists at the Australian National University say that optical microscopes should get a huge boost in magnification, after their discovery of a new high harmonic laser illumination technique, using a tiny cylinder 1/50th the width of a human hair.Co… Continue reading High harmonic lasers unlock a resolution boost for optical microscopy

What is gravitational lensing and how can the James Webb Telescope use it?

If you’ve seen the first images from the James Webb Space Telescope (JWST) this week (and let’s face it, how could you not?), you might have heard the term “gravitational lensing” being thrown around. But what does it mean exactly? And how can it help … Continue reading What is gravitational lensing and how can the James Webb Telescope use it?

Gravitational waves could reveal dark matter clouds around black holes

Dark matter is one of the most puzzling mysteries of science, with a huge range of suspects being investigated. In a new study, astronomers have searched for clouds of hypothetical, ultralight particles that could congregate around black holes, and mak… Continue reading Gravitational waves could reveal dark matter clouds around black holes

Spacetime shimmers in bumper crop of new gravitational wave detections

Astronomers have reported a bumper crop of new gravitational wave detections. The 35 new signals, comprising the third Gravitational-Wave Transient Catalog (GWTC-3), help scientists probe the depths of the cosmos in more detail.Continue ReadingCategory… Continue reading Spacetime shimmers in bumper crop of new gravitational wave detections

Optimal blood pressure in early adulthood slows the brain’s aging process

Keeping blood pressure to optimal levels might be key to keeping our brains young and healthy, according to new research

The interplay between high blood pressure and brain health is one scientists continue to shed new light on, with studies increasingly linking hypertension to a decline in cognitive function later in life. New research has drilled into the details around when exactly this relationship begins to take shape, finding that it not only begins earlier than suspected, but that even those with blood pressure at the higher end of the normal recommended range can be at risk of premature brain aging.

Injecting dead bacteria into tumors points to promising cancer treatment

Researchers have rediscovered a century-old cancer treatment, injecting dead bacteria into tumors to help the immune system target and kill the cancerous cells. Preclinical tests and early human trials indicate the treatment is safe and potentially eff… Continue reading Injecting dead bacteria into tumors points to promising cancer treatment

Gravitational wave trifecta completed as black holes eat neutron stars

Detecting gravitational waves from collisions between two black holes or two neutron stars is becoming almost mundane, but now astronomers have detected the final piece of the trifecta – a black hole swallowing a neutron star. Two separate events rolle… Continue reading Gravitational wave trifecta completed as black holes eat neutron stars

Ground-breaking night-vision film can be applied to regular glasses

Scientists at the Australian National University (ANU) have developed a new type of night-vision technology that is the first of its kind. Taking the form of an ultra-thin film, it can be applied directly to glasses to act as a filter, needing only a s… Continue reading Ground-breaking night-vision film can be applied to regular glasses

Fresh analysis reveals Laos’ ancient Plain of Jars predates the Iron Age

Dotted with thousands of giant stone vessels, the Plain of Jars in Laos is one of the most intriguing archeological sites in Southeast Asia. Now, a new study has uncovered how old the jars are, and it turns out they’ve been there much longer than previ… Continue reading Fresh analysis reveals Laos’ ancient Plain of Jars predates the Iron Age

Scientists produce rare diamonds in minutes at room temperature

While traditional diamonds are formed over billions of years deep in the Earth where extreme pressures and temperatures provide just the right conditions to crystalize carbon, scientists are working on more expedient ways of forging the precious stones… Continue reading Scientists produce rare diamonds in minutes at room temperature
