Published Earth prefers to serve life in XXS and XXL sizes


Life comes in all shapes in sizes, but some sizes are more popular than others, new research has found. A survey of body sizes of all Earth's living organisms has uncovered an unexpected pattern. Contrary to what current theories can explain, our planet's biomass -- the material that makes up all living organisms -- is concentrated in organisms at either end of the size spectrum.
Published Brightest gamma-ray burst ever observed reveals new mysteries of cosmic explosions


Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.
Published Is it COVID-19 or the flu? New sensor could tell you in 10 seconds


Have a cough, sore throat and congestion? Any number of respiratory viruses could be responsible. Today, scientists report using a single-atom-thick nanomaterial to build a device that can simultaneously detect the presence of the viruses that cause COVID-19 and the flu -- at much lower levels and much more quickly than conventional tests for either.
Published Research into birds killed in window collisions reveals their microbiomes


Researchers collected the bodies of birds that crashed into buildings while migrating, and used these specimens to learn about the relationship between birds and the microbes living in their guts -- which appears to be wildly different from mammals and their microbiomes.
Published Redness of Neptunian asteroids sheds light on early Solar System


Asteroids sharing their orbits with the planet Neptune have been observed to exist in a broad spectrum of red color, implying the existence of two populations of asteroids in the region, according to a new study by an international team of researchers.
Published Team designs molecule to disrupt SARS-CoV-2 infection


A team of scientists designed a molecule that disrupts the infection mechanism of the SARS-CoV-2 coronavirus and could be used to develop new treatments for COVID-19 and other viral diseases.
Published Temperature of a rocky exoplanet measured


An international team of researchers has used NASA's James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet's thermal emission: heat energy given off in the form of infrared light detected by Webb's Mid-Infrared Instrument (MIRI). The result indicates that the planet's dayside has a temperature of about 500 kelvins (roughly 450 degrees Fahrenheit) and suggests that it has no significant atmosphere.
Published Human body a breeding ground for antimicrobial resistance genes


The community of microbes living in and on our bodies may be acting as a reservoir for antibiotic resistance, according to new research.
Published Beneficial bacteria in the infant gut uses nitrogen from breast milk to support baby's health


A nutrition scientist who has spent his career studying breast milk has demonstrated how beneficial microbes in the gut of infants use nitrogen from human milk to support pediatric nutrition and development.
Published HIV genomes that hide in white blood cells offer new target to eliminate infections


To develop treatments that may one day entirely rid the body of HIV infection, scientists have long sought to identify all of the places that the virus can hide its genetic code. Now, in a study using blood samples from men and women with HIV on long-term suppressive therapy, a team of scientists reports new evidence that one such stable reservoir of HIV genomes can be found in circulating white blood cells called monocytes.
Published Meet the hybrid micro-robot: The tiny robot that is able to navigate in a physiological environment and capture targeted damaged cells


Researchers have developed a hybrid micro-robot, the size of a single biological cell (about 10 microns across), that can be controlled and navigated using two different mechanisms -- electric and magnetic. The micro-robot is able to navigate between different cells in a biological sample, distinguish between different types of cells, identify whether they are healthy or dying, and then transport the desired cell for further study, such as genetic analysis.
Published Researchers find clue to help plants grow with low phosphorus levels


Phosphorus is a natural mineral found in fertilizer that is essential for plant growth and development, and Earth's agricultural-grade phosphorus reserves are expected to be depleted in 50 to 100 years. A new discovery is changing their understanding of iron toxicity in plants caused by low phosphorus levels.
Published Pathogen mapped: Evolution and potential treatments


A parasite which has devastating impacts on agriculture and human health is the first pathogen to have its proteins located and mapped within its cells -- providing clues to their function and helping to identify potential drug targets.
Published RNA vaccination in rabbit mothers confers benefits to offspring in the womb


Newly developed mRNA vaccines against Zika virus and HIV-1 produced strong antibody responses that transferred from pregnant rabbits to their offspring, researchers report. As noted by the authors, the results support further development of their vaccine platform, LIONTM/repRNA, for maternal and neonatal settings to protect against mother-to-child transmission of pathogens in animals and humans.
Published A readily available dietary supplement may reverse organ damage caused by HIV and antiretroviral therapy


MitoQ, a mitochondrial antioxidant that is available to the public as a diet supplement, was found in a mouse study to reverse the detrimental effects that HIV and antiretroviral therapy (ART) have on mitochondria in the brain, heart, aorta, lungs, kidney and liver.
Published Deceptive daisy's ability to create fake flies explained


Researchers have discovered how a South African daisy makes fake lady flies on its petals to trick male flies into pollinating it.
Published As the worm turns: New twists in behavioral association theories


Physicists have developed a dynamical model of animal behavior that may explain some mysteries surrounding associative learning going back to Pavlov's dogs.
Published Harnessing power of immune system may lessen reliance on antibiotics for infections like TB


Researchers have found that the body's process of removing old and damaged cell parts, is also an essential part of tackling infections that take hold within our cells, like TB. If this natural process can be harnessed with new treatments, it could present an alternative to, or improve use of antibiotics, especially where bacteria have become resistant to existing drugs.
Published Researchers discover a way to fight the aging process and cancer development


Damage in the human genome can be repaired. But this works better in germ cells, sperm and eggs, than in normal body cells. Responsible for this is the DREAM protein complex, which prevents the activation of all available repair mechanisms. A research team has now shown that normal body cells can also be repaired better once this complex has been deactivated. In the long run, the scientists hope to develop better therapies to prevent cancer and aging-associated diseases.
Published Artificial intelligence discovers secret equation for 'weighing' galaxy clusters


Astrophysicists have leveraged artificial intelligence to uncover a better way to estimate the mass of colossal clusters of galaxies. The AI discovered that by just adding a simple term to an existing equation, scientists can produce far better mass estimates than they previously had. The improved estimates will enable scientists to calculate the fundamental properties of the universe more accurately, the astrophysicists have reported.
