Mantis shrimp larvae punch just like Ma and Pa

Researchers discover that mantis shrimp larvae can unleash powerful punches as little as 9 days after hatching, with limb accelerations reaching blistering speeds. The tiny creatures' appendages operate similarly to those of adult mantis shrimp, but scaled down, and can hurl the limb at rotational speeds of ~16,500deg/s.

Hubble watches how a giant planet grows

The Hubble Space Telescope has captured the first-ever direct image of a giant exoplanet, PDS 70b, which is feeding off material surrounding its young star. The observations provide a unique look at radiation from extremely hot gas falling onto the planet, allowing scientists to estimate how fast it's gaining mass.

Illinois, Nebraska scientists propose improvements to precision crop irrigation

Researchers developed a way to fuse high-resolution satellite data into one integrated product to track soil and plant conditions. The technology aims to redefine drought based on plant-centric metrics and provide precision irrigation with high accuracy, addressing farmer adoption challenges.

Partially sighted may be at higher risk of dementia

A new study published in Ageing Clinical and Experimental Research found that older people with vision loss are more likely to suffer mild cognitive impairment, a precursor to dementia. The research examined World Health Organisation data on over 32,000 people and found a significant correlation between vision loss and increased risk o...

Global glacier retreat has accelerated

A new study reveals that global glacier retreat has accelerated by 267 gigatonnes of ice per year on average between 2000 and 2019, contributing to rising sea levels. The loss of glacial mass is having a profound impact on mountain glaciers in the Himalayas and other regions.

Decrease in prostate cancer diagnoses due to pandemic

A new study found a 36% decrease in prostate cancer diagnoses in Sweden during the first pandemic wave, with most pronounced declines among men aged 75 and over. The number of patients receiving curative treatment remained unaffected, suggesting that healthcare prioritized cancer care during the pandemic.

Nearly $500M a year in Medicare costs goes to 7 services with no net health benefits

A UCLA-led study reveals that seven preventive medical services have no likely health benefit to patients and may even be harmful. These services, including asymptomatic bacteriuria screening and prostate cancer screening, are ordered over 31 million times annually at a cost of nearly $500 million per year.

Northern forest fires could accelerate climate change

New research reveals that northern forests' ability to absorb atmospheric carbon is being hindered by increasing frequency and intensity of forest fires. The study found that these fires are releasing more carbon into the atmosphere, while also altering the composition of tree species, with conifers being replaced by hardwoods.
