Apple defends its new anti-child-abuse tech against privacy concerns
Apple has boasted a few iconic ads during the company’s 45-year history, from the famous 1984 Super Bowl ad for Macs to the company’s combative 2019 ad campaign promising that “what happens on your iPhone stays on your iPhone.”
On Thursday, Apple announced new technologies to detect child sexual abuse material (CSAM) right on iPhones—and suddenly, it seems what’s on your iPhone no...

From a collection of molecules inspired by anti-parasitic medicines comes a potential drug candidate against COVID-19.
A microRNA network is the putative mediator of reductive stress in the heart
- ScienceDaily
- 21/8/6 23:19
Last year, researchers reported that reductive stress -- an imbalance in the normal oxidation/reduction homeostasis -- caused pathological changes associated with heart failure in a mouse model. Now, researchers describe the putative molecular regulators of this pathological chronic reductive stress -- a microRNA network.
Trials reveal efficacy and safety of oral drug for treating anemia associated with kidney disease
- ScienceDaily
- 21/8/6 23:19
Pooled results from phase 3 clinical trials demonstrate that roxadustat is efficacious and may be comparable to placebo in studies done to date for treating anemia in patients with chronic kidney disease who do not require dialysis.
Do vitamin D supplements offer kidney-related benefits for individuals with high diabetes risk?
- ScienceDaily
- 21/8/6 23:19
In a clinical trial of individuals at high risk for developing type 2 diabetes, which is the leading cause of kidney disease, vitamin D supplementation did not have significant effects on kidney health. As participants were not selected according to baseline vitamin D levels, investigators cannot exclude a kidney benefit for individuals with vitamin D deficiency.
The 'phytoplankton factory' -- from nutrients to algae growth
- ScienceDaily
- 21/8/6 23:19
Phytoplankton are the foundation of ocean ecosystems: like rainforests, they consume carbon from the atmosphere, form the basis of the marine food web and have a decisive influence on fish abundance and global climate. A recent study provides new insights into the complex biogeochemical processes at the base of the marine ecosystem.
Face masks protect against aerosolized toxins from algal blooms, study finds
- ScienceDaily
- 21/8/6 23:19
Intense blooms of toxic algae are becoming common occurrences along the coast of Florida and elsewhere. Results from a new study found that wearing the face mask everyone has become accustomed to during the COVID-19 pandemic may help protect against these airborne toxins too.
NASA Mars rover begins collecting rock in search of alien life
NASA's Perseverance rover has begun drilling into the surface of Mars and will collect rock samples to be picked up by future missions for analysis by scientists on Earth.
Scientists name new frog-legged beetle fossil for Sir David Attenborough
A new frog-legged beetle species, Pulchritudo attenboroughi, or Attenborough's Beauty, was announced today in the scientific journal Papers in Palaeontology. Frank Krell, Denver Museum of Nature & Science Senior Curator of Entomology, and Francesco Vitali, National Museum of Natural History of Luxembourg Invertebrate Zoology Collections Curator, worked together to identify this new species.
Small fungus formulations could make big difference to protect moose from winter ticks
In the battle to save moose from winter ticks, fungi on small grains of millet could be the ultimate weapon. Morris Animal Foundation-funded researchers at the University of Vermont recently produced granular formulations of insect-killing fungi and successfully tested their efficacy against winter tick larvae under laboratory conditions. The team reported their findings in Biocontrol Science and...
Defunding the police: Calls not easily transferable to other sectors without significant expenditures, adjustments
Following the killing of George Floyd by a Minneapolis police officer in May of 2020, many have argued for defunding the police. But these appeals have not been guided by research into the scale or nature of issues that police handle. A new study analyzed millions of 911 calls for service across nine U.S. police agencies to determine how defunding the police might be handled.
New device can diagnose COVID-19 from saliva samples
- ScienceDaily
- 21/8/6 21:59
A new device can detect SARS-CoV-2 from saliva in about an hour. Researchers report that the diagnostic is just as accurate as PCR tests and can identify COVID-19 variants.
New technology will allow important metals to be made more efficiently
- ScienceDaily
- 21/8/6 21:58
Researchers have invented a cheaper, safer, and simpler technology that will allow a 'stubborn' group of metals, such as the Pt-group elements, to be transformed into thin films for various practical applications.
Starving pneumonia-causing bacteria of its favorite 'food' holds promise for new antibiotics
- ScienceDaily
- 21/8/6 21:58
Researchers have revealed how the bacterium Streptococcus pneumoniae (pneumococcus) obtains the essential nutrient, manganese, from our bodies, which could lead to better therapies to target what is a life-threatening, antibiotic-resistant pathogen.
Novel molecular imaging technique casts complex coordination molecules in a new light
High-angle annular dark-field scanning transmission electron microscopy can be used to determine complex conformational structures of both crystalline and amorphous polynuclear non-planar coordination molecules, as shown by scientists from Tokyo Institute of Technology (Tokyo Tech). Using iridium as a tracer metal, they were successful in determining the different conformations of a highly...
Starving pneumonia-causing bacteria of its favorite 'food' holds promise for new antibiotics
Australian researchers have revealed how the bacterium Streptococcus pneumoniae (pneumococcus) obtains the essential nutrient, manganese, from our bodies, which could lead to better therapies to target what is a life-threatening, antibiotic-resistant pathogen.

- 21/8/6 19:14
New research published in EPJ D combines mass spectroscopy with a range of other simulation and analytical techniques, allowing researchers to distinguish between two chiral forms of a dipeptide biomolecule.
Scientists meld Twitter and satellite views to understand epic impact
Scientists are using two bird's-eye views—remote sensing from satellites and the voices of Twitter—to synthesize the environmental impacts of sprawling infrastructure projects and how the people who live amongst them feel about the changes.
Drought hits South America river, threatening vast ecosystem
The Paraná River, one of the main commercial waterways in South America, has reached its lowest level in nearly 80 years due to a prolonged drought in Brazil that scientists attribute to climate change.
