In 2017, the Minamata Convention on Mercury went into effect, designed to help curb mercury emissions and limit exposure across the globe. However, a new study of mercury levels in soil suggests that the treaty's provisions might not be enough. The study estimates that soil stores substantially more mercury than previously thought, and it predicts that increases in plant growth due to climate change may add even more. Read more ›

Between July and November of 2022, NASA's Perseverance rover collected seven samples of sediment from an ancient alluvial fan in Jezero crater. While onboard analysis gave researchers some information about their origins, only detailed analysis on Earth can retrieve evidence of when water flowed on Mars and whether life arose there. Geophysicists had hoped to get these samples back by 2033, but NASA's sample return mission may be delayed beyond... Read more ›

More efficient and longer-lasting fuel cells are essential for fuel cell-powered heavy-duty hydrogen vehicles to be an alternative to combustion fuelled counterparts. Researchers have developed an innovative method to study and understand how parts of fuel cells degrade over time. This is an important step towards the improved performance of fuel cells and them becoming commercially successful. Read more ›

A vaccine against cancer-causing human papillomaviruses (HPV) is intended to help increase the rate of HPV vaccinations, particularly in developing countries. Scientists developed a completely new vaccination concept for this purpose. The vaccine is inexpensive and protects mice against almost all cancer-causing HPV types. In addition to preventing new infections, the vaccine also triggers cellular immune responses against HPV-infected cells and may therefore also have a therapeutic effect against existing. Read more ›

Conventional cancer drugs work by triggering apoptosis, that is programmed cell death, in tumor cells. However, tumor cells have the ability to develop strategies to escape apoptosis, rendering the drugs ineffective. A research team now describes a new mechanism of action that kills cancer cells through ferroptosis. Read more ›

Researchers found discrepancies between crash reports and hospital data that might paint an incomplete or inaccurate picture of how crashes impact the safety of child passengers. Enhancing the quality of injury data reported in crash reports can aid researchers in assessing the effectiveness of various transportation safety strategies for children. Read more ›

An international research team has discovered that comammox bacteria, first identified by them in 2015, can grow using guanidine, a nitrogen-rich organic compound, as their sole energy and nitrogen source. This unique ability opens new avenues for targeted cultivation of these enigmatic microbes and could also provide a key to reducing agricultural nitrous oxide emissions. Read more ›

Caesarean section recipients are usually given prophylactic antibiotics just before the procedure to prevent later infections at the surgical site. But there have been concerns about whether these antibiotics may have a negative impact on newborns and their microbiomes if the drugs travel through the umbilical cord and reach the baby before the cord is cut. Now, a study has confirmed that although these antibiotics can cause subtle changes to... Read more ›

The distribution of species around the globe is not a random process but an outcome resulting from several evolutionary mechanisms as well as past and current environmental limitations. As a result, since the mid-19th century, biologists have identified several main regions, called biogeographic realms, that depict these large ensembles of species around the world. These biogeographic realms represent one of the most fundamental descriptions of biodiversity on Earth and are... Read more ›
