Gonadal function in male mice disrupted by prenatal risk factors

Researchers have consistently shown that prenatal exposure to Di (2-ethyhexyl) phthalate harms the reproductive system in male mice and causes fertility defects. In a new study, scientists have shown that the combination of DEHP and a high-fat diet in pregnant mice can cause more damage to pups than each factor alone.

A new weapon in the battle against antibiotic resistance: Temperature

Scientists have shown in laboratory experiments that an increase in temperature from 37 to 40 degrees Celsius increased the resistance rate for two antimicrobials, while for a third antimicrobial, the higher temperature reduced the resistance rate. If these results can be replicated in human patients, fever control could be a new way to mitigate the emergence of antibiotic resistance.

New approach against fatty liver

Fatty liver disease (steatotic liver disease, SLD for short) is increasingly causing failure of the liver as a vital organ. A team led by researchers has now discovered that a saturated fatty acid in blood vessels leads to the production of the signalling molecule SEMA3A, which closes the 'windows' in the blood vessels. This hinders the transport of fat from the liver to the adipose tissue. The researchers report that the windows open again and the fat in the liver is reduced when SEMA3A is inhibited.

Infectious H5N1 influenza virus in raw milk rapidly declines with heat treatment

The amount of infectious H5N1 influenza viruses in raw milk rapidly declined with heat treatment in laboratory research. However, small, detectable amounts of infectious virus remained in raw milk samples with high virus levels when treated at 72 degrees Celsius (161.6 degrees Fahrenheit) for 15 seconds -- one of the standard pasteurization methods used by the dairy industry. The authors of the study stress, however, that their findings reflect experimental conditions in a laboratory setting and are not identical to large-scale industrial pasteurization processes for raw milk.

New insights into the brain regions involved in paranoia

The capacity to adjust beliefs about one's actions and their consequences in a constantly changing environment is a defining characteristic of advanced cognition. Disruptions to this ability, however, can negatively affect cognition and behavior, leading to such states of mind as paranoia, or the belief that others intend to harm us. In a new study, scientists uncover how one specific region of the brain might causally provoke these feelings of paranoia. Their novel approach -- which involved aligning data collected from monkeys with human data -- also offers a new cross-species framework through which scientists might better understand human cognition through the study of other species.

And the more inclined we are to feel disgusted, the more we wash our clothes. This is shown by a unique study that examines the driving forces behind our laundering behaviours and provides new tools for how people's environmental impact can be reduced.

Which of the two DNA strands is damaged influences the cell's mutation profile

Cancer genomes are the result of diverse mutation processes that have often accumulated over decades. Scientists have analyzed the molecular evolution of tumors after exposure to mutagenic chemicals. DNA lesions that persists unrepaired over several cell generations lead to sequence variations at the site of damage, the quantification of which provides insights into the kinetics and mechanisms of DNA repair. This enabled the researchers to distinguish the contribution of the triggering lesion from that of the subsequent repair in shaping the mutation pattern.

The gender gap in life expectancy: Are eggs and sperm partly responsible?

Researchers have found that germ cells, which develop into eggs and sperm, drive sex-dependent differences in lifespan in vertebrates. Female and male germ cells increase and reduce lifespan, respectively. These effects are controlled via estrogen and growth factor hormones in females and vitamin D in males. Vitamin D supplementation extends lifespan in both males and females. The results clarify the link between reproduction and aging and show that vitamin D may improve longevity in vertebrates.
