Aliens May Be Sending Us Probing Messages Every 16 Days
Is there intelligent life out there in the universe? If so, have these intelligent aliens seen us? Have they been trying to find out more about us? New research says they may have been. A just-published scientific paper presents details of blasts of radio waves sent every 16 days from a nearby massive spiral galaxy. Are these radio waves, aimed in the direction of Earth, generated by aliens? Note that the spiral galaxy in question is 500 million light years distant: Even if the fast radio bursts (FRBs) detected were generated by an intelligent civilization, that civilization may no longer exist.

The Next Deadly Pathogen Could Come from a Rogue Scientist. Here’s How We Can Prevent That.
In the past few years, something new has become possible in biology: cheaply “printing” DNA for insertion into a cell. Kelsey Piper writes in Vox that this means a scientist who needs a particular DNA sequence to, say, create new bacteria for research can now order that DNA sequence from a lab. “But what if I asked them to print for me the genetic code of the influenza that caused the 1918 flu that killed millions of people? What if I sent them the instructions for a new disease that I have reason to believe is dangerous? What if I was doing legitimate research, but my lab didn’t adhere to modern safety standards?”

Arid American West is Moving East as Groundwater Depletes
Loss of groundwater may accelerate drying trends in the eastern United States, according to research that applied supercomputing to create an in-depth model of how groundwater will respond to warming. Even under modest climate warming scenarios, the continental United States faces a significant loss of groundwater – about 119 million cubic meters, or roughly enough to fill Lake Powell four times or one quarter of Lake Erie.

Sea Level Rise to Cause Major Economic Impact If No Climate Action Is Taken
Rising sea levels, a direct impact of the Earth’s warming climate, is intensifying coastal flooding. The findings of a new study show that the projected negative economy-wide effects of coastal flooding are already significant until 2050, but are then predicted to increase substantially towards the end of the century if no further climate action on mitigation and adaptation is taken.

Children to Bear the Burden of Negative Health Effects from Climate Change
Climate change will have grim effects on pediatric health, researchers say. The effects of climate change increase mortality and morbidity due to heat waves and fires, increased risk of food- and water-borne illnesses, and malnutrition due to food scarcity. These negative experiences bring with them psychological trauma and mental health issues that can affect both children and their caretakers.

January 2020 was Earth’s Hottest January on Record
The long-term trend of above-average temperatures continues: In the span of 141 years of climate records, there has never been a warmer January than last month, according to scientists at NOAA’s National Centers for Environmental Information. What is more, the temperature departure from average was the highest monthly departure ever recorded without an El Niño present in the tropical Pacific Ocean.

Forensic Proteomics: Going Beyond DNA Profiling
A new book details an emerging forensic method that could become as widespread and trustworthy as DNA profiling. The method is called mass-spectrometry-based proteomics, which examines the proteins that make up many parts of living things. These proteins exist in unique combinations in everything from blood cells and clothing fibers to certain types of medicine and the diseases they fight. Because proteomics analyzes these proteins directly, forensic proteomics can fill in when DNA is missing, ambiguous, or was never present to begin with.

Coastal Risks, Land Use Policy in the Face of Sea Level Rise
An Oregon land use policy creates a large economic value for some private homeowners who are allowed to protect their shoreline against erosion, according to a new study. The study highlights the tradeoff between a homeowner’s ability to protect their private property and public access to Oregon’s beaches. The study comes at a time when the future of coastal management in Oregon is up for discussion given the threats of sea-level rise due to climate change.

Framing the Climate Crisis as a Terrorism Issue Could Galvanize Action
In many vulnerable regions of the world, the climate crisis has exacerbated loss of farmable land and increased water scarcity, fueling rural-urban migration, civil unrest, and violence. As a result, worsening geopolitical instability has aided the rise of terrorism and violence in the Middle East, Guatemala, and the Lake Chad Basin of Africa. Yet when people hear the words, “global warming,” they typically don’t think of terrorism. If they did, politicians would be far more likely to undertake drastic action to address the climate crisis.

Adapting to Climate Change: Policymakers Are Thinking Too Small
When it comes to adapting to the effects of climate change, scientists and policymakers are thinking too small, according to a new research review. The authors argue that society should focus less on how individuals respond to such climate issues as flooding and wildfires and instead figure out what it takes to inspire collective action that will protect humans from climate catastrophes on a much grander scale.

The Silent Threat of the Coronavirus: America’s Dependence on Chinese Pharmaceuticals
As the new coronavirus, called 2019-nCoV, spreads rapidly around the globe, the international community is scrambling to keep up. In the midst of all of this, a potential crisis simmers in the shadows: The global dependence on China for the production of pharmaceuticals and medical equipment. Today, about 80 percent of pharmaceuticals sold in the U.S. are produced in China. This number, while concerning, hides an even greater problem: China is the largest and sometimes only global supplier for the active ingredient of some vital medications. The U.S. must develop a response plan for the inevitable shortages in the near-term and take necessary actions to reclaim control of our medical supply chain. Continuing to overlook this long-known vulnerability will only lead to catastrophe.

Glaciers May Offer Safe Sites for Nuclear Waste Storage
New insights into rates of bedrock erosion by glaciers around the world will help to identify better sites for the safe storage of nuclear waste. The findings of a new research overturn earlier research, showing that erosion rates do not increase with the speed of glacier flow as quickly as previously anticipated.

More Rain and Less Snow Means Increased Flood Risk
By analyzing more than two decades of data in the western U.S., scientists have shown that flood sizes increase exponentially as a higher fraction of precipitation falls as rain, offering insight into how flood risks may change in a warming world with less snow.

Building a Flood-Resilient Future
Seven of the U.K. ten wettest years on record have occurred since 1998. Its wettest winter in history came in 2013, and the next wettest in 2015. In a single week in November 2019, 400 homes were flooded and 1,200 properties evacuated in northern England. The frequency and severity of these events is expected to increase as a result of climate change, meaning that many more communities will suffer their devastating effects. A new book shows how we can adapt the built and natural environment to be more flood resilient in the face of climate change.
