Oysters exposed to polystyrene microplastics produced fewer offspring, which were also smaller and slower growing than offspring from unexposed oysters, according to recent research. The researchers say their study adds to growing evidence of the harm caused by microplastic pollution and can help stakeholders to take action on plastic debris entering the oceans to limit its long-term impact on marine life.

Bumblebees are negatively affected by the insecticide azadirachtin even at concentrations 50 times lower than the recommended levels used by farmers, recent laboratory experiments have revealed. No males hatched in laboratory colonies that were fed on recommended levels of the pesticide and, even at concentrations 50 times lower, the males that did hatch were deformed, and there were significantly fewer compared to an untreated colony.

Agri-environment schemes (AES) have been implemented throughout Europe to mitigate against the negative effects of agricultural intensification. Although these schemes have shown positive effects on the abundance and richness of certain species and taxa, the impact of AES on reproduction of target species at the local and landscape scale is poorly understood. This large-scale study looked for the effect of selected AE measures on bumblebee reproduction. Results indicate that bumblebee reproduction is significantly higher on sown flower patches when compared to conventional management. Although the increase is most pronounced at the plot scale, higher reproduction was found in landscapes surrounding larger sown plots (at least one hectare) compared to smaller sown plots.

Farmers could help to maintain populations of bees and other pollinators by sowing inexpensive seed mixes on their land, a new study suggests. Researchers surveyed pollinators visiting study plots in Berkshire, UK, and explored how sowing different seed mixes and using different management techniques affected the flowers produced and the pollinators visiting them.

An apparatus for compensating for pixel distortion while reproducing hologram data includes an extraction unit, a determination and calculation unit, a table, and a compensation unit. The extraction unit extracts a reproduced data image from a reproduced image frame including the reproduced data image and borders. The determination and calculation unit determines position values of edges of the extracted reproduced data image, and calculates average magnification error values of pixels within line data from position values of start and end point pixels thereof, which are based on the determined position values of the edges. The table stores misalignment compensation values for the pixels within the line data, wherein the misalignment compensation values correspond to predetermined references for average magnification error values. The compensation unit compensates for pixel positions in the extracted reproduced data image using the misalignment compensation values that correspond to the calculated average magnification error values.

A method for virtual channel management is provided. The method includes the following steps. In response to a command, a control unit of a network-based multimedia reproduction system determines whether the command is associated with virtual channel switching. When the command is associated with virtual channel switching, the control unit checks whether a channel value corresponding to the command exists in an application virtual channel table. When the channel value exists in the application virtual channel table, the control unit determines an application corresponding to the channel number from the application virtual channel table, and executes the application. According to a first operation parameter set corresponding to the application, the control unit sets the executed application to retrieve digital contents through a network unit of the network-based multimedia reproduction system.

A reproduction apparatus comprises a reproduction unit configured to reproduce image data from a recording medium; a detection unit configured to detect users; and a generation unit configured to generate, for each of a plurality of users, management information for distinguishing a portion that has been reproduced and a portion that has not been reproduced in the image data recorded in the recording medium.

In a case where (i) a reflectance calculated from a reflected light amount obtained from a longest pit (P1max) or a longest space (S1max) in a first pit row is defined as a first reflectance and (ii) a reflectance calculated from a reflected light amount obtained from a longest pit (P2max) or a longest space (S2max) in the second pit row is defined as a second reflectance, the first pit row is formed such that the first reflectance becomes substantially identical with the second reflectance.

The present disclosure relates to a reproduction apparatus. The reproduction apparatus may comprise an optical filter and electric filters.

Immunosenescence is a well-known phenomenon in mammal systems, but its relevance in other long-lived vertebrates is less understood. Further, the influence of age and reproductive effort on immune function in long-lived species can be challenging to assess, as long-term data are scarce and it is often difficult to sample the oldest age classes. We used the painted turtle (Chrysemys picta) to test hypotheses of immunosenescence and a trade-off between reproductive output and immune function in a population of a long-lived vertebrate that has been monitored for over 30 years. These long-term data are utilized to employ a unique approach of aging turtles with mark-recapture data and population-specific growth modeling to obtain more accurate estimates of age. We analyzed natural antibodies, lysis ability, and bactericidal competence in 126 individuals from 1 to 33 years of age captured during May and June in 2011. Older turtles exhibited greater natural antibody levels than young individuals across sexes. Young females with large clutches exhibited greater lysis ability, while older females with large clutches had decreased lysis ability, suggesting a trade-off between reproductive output and immune function conditional upon age. However, bactericidal competence increased later in the nesting season for older females. Our study rejects the hypothesis of immunosenescence in a long-lived turtle, despite evidence of actuarial and reproductive senescence in this population. Additionally, we detected mixed evidence for a trade-off between reproduction and immune health.

Prostate cancer has greater probabilities of happening in men who seek medical care for infertility and assisted reproduction compared to those who became fathers by natural means.

At the daily No10 briefing this evening, Dominic Raab pointed to the experience in Germany as he warned that easing the draconian restrictions too early risks 'undoing all the hard work'.

The research, which was published in Current Biology, is aimed at studying about how the reproduction process evolved in the plants over the years.
