Biophysics: Testing how well biomarkers work

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

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

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

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

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

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

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.

Bioluminescence first evolved in animals at least 540 million years ago

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.

Critical minerals recovery from electronic waste

24/04/2024
A nontoxic separation process recovers critical minerals from electronic scrap waste.

Asian monsoon lofts ozone-depleting substances to stratosphere

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

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.

This tiny chip can safeguard user data while enabling efficient computing on a smartphone

24/04/2024
A new chip can efficiently accelerate machine-learning workloads on edge devices like smartphones while protecting sensitive user data from two common types of attacks -- side-channel attacks and bus-probing attacks.

Livestock abortion surveillance could protect livelihoods and detect emerging global pathogens

24/04/2024
A study suggests timely reporting and investigating of livestock abortions is feasible in rural areas and can provide insights into emerging infectious diseases.

Warming climate is putting more metals into Colorado's mountain streams

24/04/2024
Warming temperatures are causing a steady rise in copper, zinc and sulfate in the waters of Colorado mountain streams affected by acid rock drainage. Concentrations of these metals have roughly doubled in these alpine streams over the past 30 years, presenting a concern for ecosystems, downstream water quality and mining remediation, according to a new study. Natural chemical weathering of bedrock is the source of the rising acidity and metals, but the ultimate driver of the trend is climate change, the report found, and the results point to lower stream volumes and exposure of rock once sealed away by ice as the likely causes.

Don't be a stranger -- study finds rekindling old friendships as scary as making new ones

24/04/2024
Psychologists have found that people are as hesitant to reach out to an old friend as they are to strike up a conversation with a stranger, even when they had the capacity and desire to do so.

Super Mario hackers' tricks could protect software from bugs

23/04/2024
Video gamers who exploit glitches in games can help experts better understand buggy software, students suggest.

Infected: Understanding the spread of behavior

23/04/2024
A team of researchers found that long-tie connections accelerate the speed of social contagion.

Researchers create artificial cells that act like living cells

23/04/2024
Researchers describe the steps they took to manipulate DNA and proteins -- essential building blocks of life -- to create cells that look and act like cells from the body. This accomplishment, a first in the field, has implications for efforts in regenerative medicine, drug delivery systems and diagnostic tools.

Marginalized communities developed 'disaster subculture' when living through extreme climate events

23/04/2024
An assistant professor conducted a study in which he lived among one of the poorest, most marginalized communities in Seoul, South Korea. In the ethnographic study, he asked residents how they dealt with extreme heat. He found they tended to accept the conditions, stating there was not much that could be done. That shows people accepted extreme climate events, despite evidence showing this should not be normal, which bodes the argument social work as a field has much to do to help address climate emergencies.

New study uncovers lasting financial hardship associated with cancer diagnosis for working-age adults in the U.S.

23/04/2024
A new study highlights the lasting financial impact of a cancer diagnosis for many working-age adults and their families in the United States. It shows a cancer diagnosis and the time required for its treatment can result in employment disruptions, loss of household income and loss of employment-based health insurance coverage, leading to financial hardship.
