How dangerous are kilonovae?

When we look up at the sky on a particularly dark night, there is a sense of timelessness. We might see the flash of a meteor, and occasionally a comet is visible to the naked eye, but the cold and distant stars are unchanging. Or so it seems. There can also be a sense of calm, that despite all the uncertainty of the world, the stars will always watch over us.

A super-Earth (and possible Earth-sized) exoplanet found in the habitable zone

Astronomers have found a new Super-Earth orbiting an M-dwarf (red dwarf) star about 137 light-years away. The planet is named TOI-715b, and it's about 1.55 Earth's radius and is inside the star's habitable zone. There's also another planetary candidate in the system. It's Earth-sized, and if it's confirmed, it will be the smallest habitable zone planet TESS has discovered so far.

Atmospheres in the TRAPPIST-1 system should be long gone

Trappist-1 is a fascinating exoplanetary system. Seven worlds orbiting a red dwarf star just 40 light-years away. All of the worlds are similar to Earth in mass and size, and three or four of them are potentially habitable. Imagine exploring a system of life-rich worlds within easy traveling distance of each other. It's a wonderful dream, but as a new study shows it isn't likely that life exists in the system. It's more likely the planets are barren and stripped of their atmospheres.

How could laser-driven lightsails remain stable?

It's a long way to the nearest star, which means conventional rockets won't get us there. The fuel requirements would make our ship prohibitively heavy. So an alternative is to travel light.

Number of shark bites in 2023 found to be consistent with recent trends, with small spike in fatalities

There was an increase in the number of unprovoked shark attacks worldwide and an uptick in fatalities in 2023 compared to the previous year. The University of Florida's International Shark Attack File (ISAF), a scientific database of global shark attacks, confirmed 69 unprovoked bites in 2023. Although this is higher than the most recent five-year average of 63 attacks, the data remain consistent with long-term trends.

New findings explain how soil traps plant-based carbon

When carbon molecules from plants enter the soil, they hit a definitive fork in the road. Either the carbon gets trapped in the soil for days or even years, where it is effectively sequestered from immediately entering the atmosphere.

How food availability could catalyze cultural transmission in wild orangutans

The proverb "necessity is the mother of invention" has been used to describe the source from which our cultural evolution springs. After all, need in times of scarcity has forced humans to continually invent new technologies that have driven the remarkable cumulative culture of our species. But an invention only becomes cultural if it is learned and spread by many individuals. In other words, the invention must be socially transmitted.

Bioaerosols containing airborne microorganisms and their waste products can cause respiratory disorders and other adverse health effects, such as hypersensitivity pneumonitis and toxic responses.

Research team develops cold-hardiness kiwi fruit for immediate release to public

Kiwi fruits with their tangy green flesh are routinely purchased and devoured throughout the year by people across the nation. This is no surprise. Kiwi fruit is high in vitamin C, dietary fiber, and potassium. The subtropical fruit is also a favorite of many southern U.S. producers since the delicious fruit is traditionally grown in warmer climates. California produces the vast majority of kiwi fruits that are sold in our local grocery stores, but due to recent research advancements from U.S. Department of Agriculture scientists, this may no longer be the case.

Pulmonary rehabilitation is difficult for millions of Americans to access, says new study

Pulmonary rehabilitation, an essential component of care for patients with chronic respiratory conditions, is difficult for millions of Americans to access, a new Yale-led study reveals. The findings, researchers say, reveal geographic regions where this type of care is most lacking and illustrate the potential for telemedicine in helping to bridge this gap.

Unlocking precision medicine for inflammatory bowel disease

The prevalence of inflammatory bowel disease (IBD), encompassing ulcerative colitis (UC) and Crohn's disease (CD), is rapidly increasing worldwide, affecting an estimated 6.8 million people. This surge brings significant economic burdens, with annual health care costs exceeding $12,000 and $7,000 for CD and UC patients, respectively. Tailored drug selection based on individual factors can potentially reduce these costs and improve patient outcomes.

Study: Running won't help you lose weight, but it does prevent weight gain

Recently, some media outlets have highlighted that it is a myth that running will help you lose weight/fat. There is certainly convincing scientific evidence that after an initial loss in fat mass from engaging in an exercise regime, the body lowers its overall energy expenditure to conserve energy and ultimately its fat mass stores. This is nature's insurance policy developed by our ancestors to prevent starvation during times of restricted food availability.

Epigenetic combination therapy could overcome treatment resistance in epithelioid sarcomas and rhabdoid tumors

Epithelioid sarcoma, a rare aggressive cancer that usually strikes young adults, and rhabdoid tumors, which affect children, have long been difficult to treat.

Lipid traffic jam: Scientists reveal how dAcsl orchestrates lipid transport in Drosophila

Interorgan lipid transport is crucial for organism development and the maintenance of physiological function. Drosophila long-chain acyl-CoA synthetase (dAcsl), which catalyzes the conversion of fatty acids into acyl-coenzyme As (acyl-CoAs), plays a critical role in regulating systemic lipid homeostasis. But what happens when this enzyme is deficient, and how does it impact the delicate balance of interorgan lipid transport?

Team discovers how to predict whether patients with leukemia will be sensitive to epigenetic drugs

Alterations in the chemical modifications that control gene expression, known as epigenetics, have proven to be one of the most characteristic properties of all human tumors. This realization has generated the development of intense pharmacological research to find drugs that act at this level against cancer. Today there are nine epigenetic drugs approved for use in oncology, especially in leukemias, lymphomas and soft tissue tumors. However, a mystery remains: Why do some patients respond clinically to these compounds others show resistance to their action?

Best of Last Week—newborn great white shark, Avocado the robot, diets that can alter immune system

It was a good week for the biological sciences as an evolutionary ecologist at the University of California, Riverside, working with a filmmaker from Malibu Artists Inc., observed and reported the first-ever sighting of a live newborn great white shark—Phillip Sternes and Carlos Gauna were using a drone camera to capture shark imagery when they spotted the pure white shark off the California coast. Also, a combined team of biologists from Aarhus University and the University of Oxford found evidence that culling animals who "don't belong" can be a flawed nature conservation practice—killing non-native animal species because they are thought to harm native plant species, they contend, does not take into consideration the original impact of native megafauna. And a team led by Yinan Zhang at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences reported that an inner ear fossil from a 6-million-year-old ape revealed clues about the evolution of human movement.

New research shows some gains but fresh difficulties in combating child sexual abuse

Child sexual abuse is common in Australia. The best evidence of this comes from the 2023 Australian Child Maltreatment Study (ACMS), which surveyed 8,500 Australians aged 16 and over. The ACMS found 28.5% of the national population has experienced sexual abuse before age 18 by any person (adult or adolescent). Women were twice as likely as men to have experienced sexual abuse (37.3%-18.8%). Among 16-to-24-year-olds, prevalence was slightly lower (25.7%), but again with a massive gender disparity (35.2%-14.5%).
