Reckoning with the U.S Role in Global Ocean Plastic Waste concludes plastic waste in the U.S. is ubiquitous and increasing. Worldwide, at least 8.8 million metric tons of plastic waste enter the world’s oceans each year — the equivalent of dumping a garbage truck of plastic into the ocean every minute — and in 2016…
UC Riverside-led mouse study finds a receptor greatly contributes to the harmful effects of plastic-associated chemicals
Researchers at Princeton University and the University of Washington have developed an ultracompact camera the size of a coarse grain of salt. The new system can produce crisp, full-color images on par with a conventional compound camera lens 500,000 times larger in volume.
In mice and in human tissue, a new compound discovered at Princeton disables a key gene that’s implicated in breast, prostate, liver, lung, colon and other cancers.
The Arctic Ocean has been getting warmer since the beginning of the 20th century – decades earlier than records suggest – due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean.
Engineering physics PhD student Khadijeh Miarabbas Kiani has fabricated a laser on silicon using a simple, cost-effective method - something that has been a longstanding challenge in the field of silicon photonics. [...]Read More...
To understand how the pandemic is evolving, it’s crucial to know how death rates from COVID-19 are affected by vaccination status.
The cost of lithium-ion batteries for phones, laptops, and cars has plunged over the years, and an MIT study shows just how dramatic that drop has been. The change is akin to that of solar and wind energy, and further declines may yet be possible, the researchers say.
Researchers have developed an injectable therapy based on nanofibers that has enabled paralyzed mice with severe spinal cord injuries to regain the ability to walk.
Dopamine is a neurotransmitter involved in the body’s system for reward and pleasure. A recent trend has people avoiding stimulating activities in the belief that doing so allows the body to rese...
MIT physicists have confirmed that as atoms are chilled and squeezed to extremes, their ability to scatter light is suppressed, making them less visible. The findings show the Pauli exclusion principle, or Pauli blocking, applies not just to electrons but also to atoms.
Ninety per cent of cancer deaths are caused by metastasis, that is to say, the spread of the primary tumour to other organs. Scientists led by ICREA researcher Dr. Salvador Aznar-Benitah at IRB Barcelona have described the mechanism by which a diet rich in palmitic acid makes tumour cells more aggressive, conferring…
High expression of the fitness gene hFwe-Lose in the lung reliably predicts severe progression
Purdue University is a world-renowned, public research university that advances discoveries in science, technology, engineering and math.
Bar-tailed Godwits regularly travel more than 7,000 miles non-stop. One enthusiast is spreading the word of their amazing migrations, with the help of a research project tracking 20 tagged birds in...
More than 40 healthcare professionals and legal experts have issued the first guidance of its kind to support people with type 1 diabetes using Do-it-Yourself (DIY) technology driven systems to manage their condition.
Human neurons have a lower density of ion channels than expected, compared to neurons of other mammals, according to a new study. The researchers hypothesize that a lower channel density may have helped the human brain evolve to operate more efficiently.
R is the response to selection, S is the selection differential, and h 2 is the narrow-sense heritability. This is the workhorse equation for quantitative genetics. The selective differential S, is the difference between the population average and the average of the parental population (some subset of the total…
Engineers have successfully transferred digitally encoded information wirelessly using nuclear radiation instead of conventional technology.
Some people claim nuclear fuel is inexhaustible and circular, others say we'll run out soon. We do the math. Turns out, it's roughly as inexhaustible as sunlight.
Treatment with the amino acid arginine enhanced the effectiveness of radiation therapy in cancer patients with brain metastases in a clinical trial from investigators at Weill Cornell Medicine and Angel H. Roffo Cancer Institute.
We were priviliged and excited to have the opportunity for a behind-the-scenes tour of wild bee colonies at Blenheim Palace led by Filipe Salbany, an internationally experienced bee expert who emit…
World-first psilocybin clinical trial in the treatment of Generalised Anxiety Disorder receives ethics approval
A landmark paper proves that obesity is not just energy in and out; the type of food matters. And while one study shows we’re eating more processed food, another reveals what can be gained if we clean up our act.
