Researchers unveil PI3K enzyme's dual accelerator and brake mechanisms

Science Daily - 24/04/2024
The enzyme PI3K plays a critical role in cell migration. Scientists have long understood this function. But researchers have recently unveiled that a subunit of this enzyme also has the ability to slam on the breaks to this process.

Holographic displays offer a glimpse into an immersive future

Science Daily - 24/04/2024
Researchers have invented a new optical element that brings us one step closer to mixing the real and virtual worlds in an ordinary pair of eyeglasses using high-definition 3D holographic images.

How parasites shape complex food webs

Science Daily - 24/04/2024
A new study sheds light on how parasites, often overlooked, can dramatically affect the balance between predator and prey populations. Researchers developed a groundbreaking mathematical framework that predicts when predators, prey, and parasites can coexist, considering factors like random fluctuations and parasite effects on both populations. This research provides a valuable tool for conservation by helping predict how parasites influence ecosystem resilience and informing strategies to protect vulnerable species.

This salt battery harvests osmotic energy where the river meets the sea

Science Daily - 24/04/2024
Estuaries -- where freshwater rivers meet the salty sea -- are great locations for birdwatching and kayaking. In these areas, waters containing different salt concentrations mix and may be sources of sustainable, 'blue' osmotic energy. Researchers report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new design had an output power density more than two times higher than commercial membranes in lab demonstrations.

AI tool recognizes serious ocular disease in horses

Science Daily - 24/04/2024
Researchers have developed a deep learning tool that is capable of reliably diagnosing moon blindness in horses based on photos.

Modeling broader effects of wildfires in Siberia

Science Daily - 24/04/2024
As wildfires in Siberia become more common, global climate modeling estimates significant impacts on climate, air quality, health, and economies in East Asia and across the northern hemisphere.

Researchers find oldest undisputed evidence of Earth's magnetic field

Science Daily - 24/04/2024
A new study has recovered a 3.7-billion-year-old record of Earth's magnetic field, and found that it appears remarkably similar to the field surrounding Earth today.

Biophysics: Testing how well biomarkers work

Science Daily - 24/04/2024
Researchers have developed a method to determine how reliably target proteins can be labeled using super-resolution fluorescence microscopy.

Shoreline model predicts long-term future of storm protection and sea-level rise

Science Daily - 24/04/2024
Researchers have created a coastal evolution model to analyze how coastal management activities on barrier islands, meant to adapt to sea-level rise, can disrupt natural processes that are keeping the barrier islands above water. Replenishing beaches and clearing over-washed roads may not be the best long term strategy.

High-resolution lidar sees birth zone of cloud droplets

Science Daily - 24/04/2024
Scientists demonstrated the first-ever remote observations of the fine-scale structure at the base of clouds. The results show that the air-cloud interface is a transition zone where aerosol particles suspended in Earth's atmosphere give rise to the droplets that ultimately form clouds. The research will enable scientists to gain insight into how changes in atmospheric aerosol levels could affect clouds and climate.

Making diamonds at ambient pressure

Science Daily - 24/04/2024
Researchers have grown diamonds under conditions of 1 atmosphere pressure and at 1025 degrees Celsius using a liquid metal alloy composed of gallium, iron, nickel, and silicon, thus breaking the existing paradigm. The discovery of this new growth method opens many possibilities for further basic science studies and for scaling up the growth of diamonds in new ways.

Eruption of mega-magnetic star lights up nearby galaxy

Science Daily - 24/04/2024
While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays -- high-energy photons -- coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none. An international team realized that the burst must have been an extra-galactic flare from a magnetar, a young neutron star with an exceptionally strong magnetic field.

A simple 'twist' improves the engine of clean fuel generation

Science Daily - 24/04/2024
Researchers have found a way to super-charge the 'engine' of sustainable fuel generation -- by giving the materials a little twist. The researchers are developing low-cost light-harvesting semiconductors that power devices for converting water into clean hydrogen fuel, using just the power of the sun. These semiconducting materials, known as copper oxides, are cheap, abundant and non-toxic, but their performance does not come close to silicon, which dominates the semiconductor market.

A novel universal light-based technique to control valley polarization in bulk materials

Science Daily - 24/04/2024
Scientists report a new method that achieves for the first time valley polarization in centrosymmetric bulk materials in a non-material-specific way. This 'universal technique' may have major applications linked to the control and analysis of different properties for 2D and 3D materials, which can in turn enable the advancement of cutting-edge fields such us information processing and quantum computing.

 Future Skills at Monash College and Microsoft partner to transform tech education with AI

Bioluminescence first evolved in animals at least 540 million years ago

Science Daily - 24/04/2024
Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study. The study focuses on an ancient group of marine invertebrates that includes soft corals, pushes back the previous oldest dated example of trait by nearly 300 million years.

New type of host defence against Zika, dengue infections revealed

The Hindu:Science - 24/04/2024
Scientists have identified a novel defence mechanism the human body uses to prevent some viruses from transmitting via non-conventional routes

Critical minerals recovery from electronic waste

A nontoxic separation process recovers critical minerals from electronic scrap waste.

Asian monsoon lofts ozone-depleting substances to stratosphere

Science Daily - 24/04/2024
Powerful monsoon winds, strengthened by a warming climate, are lofting unexpectedly large quantities of ozone-depleting substances high into the atmosphere over East Asia, according to new research. The study found that the East Asian Monsoon delivers more than twice the concentration of very short-lived ozone-depleting substances into the upper troposphere and lower stratosphere than previously reported.

World's chocolate supply threatened by devastating virus

Science Daily - 24/04/2024
A rapidly spreading virus threatens the health of the cacao tree and the dried seeds from which chocolate is made, jeopardizing the global supply of the world's most popular treat. Researchers have developed a new strategy: using mathematical data to determine how far apart farmers can plant vaccinated trees to prevent mealybugs from jumping from one tree to another and spreading the virus.
