DJI Air 3 (RC-N2)

DJI Air 3 (RC-N2) captures 4K mapping passes and environmental surveys with dual cameras, long flight time, and omnidirectional obstacle sensing.

Reducing double-strand DNA break repair exacerbates vascular aging

Researchers found that DNA damage accumulates in arteries with aging and contributes to impaired vascular function. In mice lacking or heterozygous for the double-strand DNA break repair protein ATM kinase, aging accelerated vascular dysfunction, including increased arterial stiffness and oxidative stress.

Sex pays off

Research shows that asexual reproduction in stick insects, such as parthenogenesis, reduces genetic variability and slows down adaptation to environmental changes. This negatively impacts the speed of adaptation and genetic diversity in these insects.

CalDigit TS4 Thunderbolt 4 Dock simplifies serious desks with 18 ports for high-speed storage, monitors, and instruments across Mac and PC setups.

UCLA study of threatened desert tortoises offers new conservation strategy

A UCLA study published in Science found that desert tortoises with higher genetic variation had higher survival rates after relocation. The researchers analyzed blood samples from 79 surviving and 87 deceased tortoises and found that survivors averaged 23% greater heterozygosity than those that perished.

Sky & Telescope Pocket Sky Atlas, 2nd Edition is a durable star atlas for planning sessions, identifying targets, and teaching celestial navigation.

Genetic study shows major impact of climate change on Antarctic fur seals

A genetic study reveals that climate change has significantly impacted Antarctic fur seals, leading to a decline in the population due to changes in food availability. The seals' ability to adapt is hindered by the lack of heritability of 'fitness genes', resulting in a decrease in survival and breeding success.

Aranet4 Home CO2 Monitor

Aranet4 Home CO2 Monitor tracks ventilation quality in labs, classrooms, and conference rooms with long battery life and clear e-ink readouts.

The spice of life: Variety is also good for hares

A new study published in Molecular Ecology found that hares with genetic variation at a specific gene locus have higher reproductive success, including increased fertility and fecundity. The research suggests that variability at the individual level can provide advantages for survival and reproduction.

Unfaithful songbirds increase offspring fitness

Research on blue tits found that extra-pair copulations with distant males lead to more heterozygous offspring, resulting in improved survival and reproductive success. This study suggests that females can benefit from promiscuity by increasing the genetic quality of their progeny.

Got milk? Scientists discover key lactation gene

Researchers identify XOR as essential for enveloping milk fat droplets with phospholipid bilayer. Heterozygous XOR-mutant females fail to secrete milk fat, leading to premature involution of mammary gland and lactation insufficiency.
