Bubbles In Ice Could Be A Future Medium For Secret Codes
Scholars have developed a method to encode binary and Morse code messages in ice. A 'message in a bubble' has limited practical utility, information storage in Antarctica and the Arctic is expensive but less challenging than storing message in ice, but they are more covert than paper documents ...
Isoprene: Plants Can Make Their Own Pesticide But The Environmental Cost Is High
As the developed world becomes more removed from science and health, it is easier to embrace beliefs that science and medicine are not needed at all, with some claiming that vaccines and pesticides are not really needed, the natural world can do it without modern tools.Companies will cater to that ...
Europe Ponders Another Year Trying To Combat Fall Armyworm Without Modern Pesticides

Meta-Analysis: Flower Strips With Two Or More Species May Reduce Pesticides
A new paper has found that flower strips along fields and ditches may be more than just a gimmick that lets people feel like they are improving the environment or saving bees.

Nearly Complete Harbin Skull From 146,000 Years Ago Belongs To The Denisovan Lineage
The discovery of the Denisovans 15 years ago set off a chain of evolutionary research into how they contributed to modern East Asians and Oceanians. A new study adds evidence. Researchers have confirmed that a nearly complete hominin skull from 146,000 years ago that was discovered near Harbin ...
The Lizard Poop Of Madagascar
Some 88 million years ago, Madagascar broke off from India.Isolated from all other landmasses, plants and animals evolved in seclusion, creating a biodiversity hotspot unlike anywhere else on Earth. One way biodiversity spreads is by endozoochory, which is the process name for animals eating plant ...
Chinese Researchers Are Rewiring Brains Using Interfaces
Human evolution and culture have been shaped by our increasing ability to communicate. A new review from China believes that brain-computer interfaces mark the next leap: a direct connection between mind and machine. They note breakthroughs in neural signal decoding, AI, and bioengineering but ...
Activin-A: Muscle Weakness In Cancer Survivors May Be Treatable
Tumors can destroy the blood vessels of muscles even when the muscles are nowhere close to the tumor. That is the key finding of a new study that my colleagues and I recently published in the journal Nature Cancer.Muscle loss in cancer patients is a major health problem, but the exact causes of ...
Like Food Coloring Now, Cultural Mullahs Once Claimed Mexican Food Was A Gateway To Disease

Taurine’s Anti-Aging Hype Takes A Hit In Rigorous New Study
A new study is pouring cold water on the idea that taurine – a nutrient found in the body and in foods – is a magic bullet for aging. Researchers led by Maria Emilia Fernandez at the U.S. National Institute on Aging found that taurine levels in blood do not reliably decline with age in humans ...
Phytosterols In Vegetarian Diets Linked To Lower Risk Of Diabetes
Diets high in phytosterols, such as vegetarian diets, have long been linked to lower risk of heart disease and diabetes by lowering low-density lipoprotein (LDL) cholesterol but food surveys, questionnaires, and diaries are not reliable enough to make clinical determinations while in mouse experiments ...
The End To Universities Using Graduate Students As Piggy Banks Is Near

UC Davis Epidemiologists Out To Scare New Mothers Again
In the modern era we can detect anything in anything. Being able to detect in parts per billion, trillion and even quadrillion means that if an epidemiologist can "correlate" a chemical to harm in a spreadsheet, someone raising money opposing science can weaponize the result.A new paper finding ...
The Right Of Return Is Complicated
My June 28 column on the Middle East drew a comment concerning Palestinians ejected from their homes by the post-WWII influx of European Jewish refugees to what’s now Israel.
