17 <title>Selenoproteins open new strategies for treating certain cancers in children</title>
18 <description>Selenoproteins are crucial for several biological functions, including the breakdown of harmful substances, immune system support, and regulating metabolic processes. However, in specific contexts, these proteins can be misused and shield cancer cells from death. One such protein, glutathione peroxidase 4 (GPX4), is vital in supporting cellular protection and cancer cell survival.</description>

25 <title>A new way to detect daisy worlds</title>
26 <description>The daisy world model describes a hypothetical planet that self-regulates, maintaining a delicate balance involving its biogeochemical cycles, climate, and feedback loops that keep it habitable. It's associated with the Gaia Hypothesis developed by James Lovelock. How can we detect these worlds if they're out there?</description>

33 <title>Extreme heat weakens land's power to absorb carbon, analysis finds</title>
34 <description>A new European Space Agency-backed study shows that the extreme heat waves of 2023, which fueled huge wildfires and severe droughts, also undermined the land's capacity to soak up atmospheric carbon. This diminished carbon uptake drove atmospheric carbon dioxide levels to new highs, intensifying concerns about accelerating climate change.</description>

49 <title>Saturday Citations: Cold dark matter takes a hit; a new paradigm for biology; those fracking earthquakes</title>
50 <description>This week, researchers formulated a new method to calculate the probability of generating intelligent life in the universe. Investigations of a meteorite that originated on Mars revealed that it once interacted with liquid water. And an analysis of fossilized teeth suggests that long childhoods are a precondition for the evolution of large brains. Additionally, astronomers threw cold water on cold dark matter; biologists suggested a new, holistic approach to the field; and if we have to frack, we might as well do it with fewer earthquakes.</description>

57 <title>Methylmercury: How microbes create the most toxic form of mercury</title>
58 <description>Mercury is extraordinarily toxic, but it becomes especially dangerous when transformed into methylmercury—a form so harmful that just a few billionths of a gram can cause severe and lasting neurological damage to a developing fetus. Unfortunately, methylmercury often makes its way into our bodies through seafood—but once it's in our food and the environment, there's no easy way to get rid of it.</description>

66 <description>There's only one thing worse than an abusive boss—and that's a boss who thinks they can make up for their bad behavior by turning on the charm the following day. That's the key finding from a new study from researchers at Stevens Institute of Technology, which shows that employees' morale and job performance decline sharply when leaders lurch unpredictably between good and bad behavior.</description>

81 <title>Study challenges assumptions about how tuberculosis bacteria grow</title>
82 <description>The rod-shaped tuberculosis (TB) bacterium, which the World Health Organization has once again ranked as the top infectious disease killer globally, is the first single-celled organism ever observed to maintain a consistent growth rate throughout its life cycle. These findings, reported by Tufts University School of Medicine researchers on November 15 in the journal Nature Microbiology, overturn core beliefs of bacterial cell biology and hint at why the deadly pathogen so readily outmaneuvers our immune system and antibiotics.</description>

121 <title>Scientists gain new insights into how mass is distributed in hadrons</title>
122 <description>Scientists can determine the mass of subatomic particles that are built from quarks by looking at the particles' energy and momentum in four-dimensional spacetime. One of the quantities that encode this information, called the trace anomaly, is linked to the fact that physical observables from high-energy experiments depend on the energy/momentum scales involved.</description>

130 <description>The idea of maturing oocytes in the ovary to produce offspring has been implemented in various ways. One such method, ovarian transplantation, is a relatively simple procedure for obtaining eggs, compared to in vitro culture of ovaries and follicles. However, it is still difficult to transplant ovaries into cellular immunodeficient mice and produce offspring from the eggs grown in the mice.</description>

138 <description>Modern imaging systems, such as those used in smartphones, virtual reality (VR), and augmented reality (AR) devices, are constantly evolving to become more compact, efficient, and high-performing. Traditional optical systems rely on bulky glass lenses, which have limitations like chromatic aberrations, low efficiency at multiple wavelengths, and large physical sizes. These drawbacks present challenges when designing smaller, lighter systems that still produce high-quality images.</description>

162 <description>To the casual eye, a memory foam mattress would appear to have no relationship to the behavior of cells and tissues. But an innovative study carried out at the Centro de Investigaciones Cardiovasculares (CNIC) in Madrid shows that viscoelasticity—the capacity of a material to be compressed and then recover its original form, like memory foam—is a little-explored property of biological tissues that is essential for correct cell function.</description>
