Northeast farmers face warming climate, drenched fields
For the past two decades, the Northeast has been getting warmer for longer periods of time. It also has seen a 71 percent increase in the frequency of extreme precipitation events – more than any other region in the United States. Farmers in the Northeast are adapting to longer growing seasons and warming climate conditions – but they may face spring-planting whiplash as they confront fields increasingly saturated with rain.

A portable, shoe-box-sized chemical detector
A chemical sensor prototype will be able to detect “single-fingerprint quantities” of substances from a distance of more than 100 feet away, and its developers are working to shrink it to the size of a shoebox. It could potentially be used to identify traces of drugs and explosives, as well as speeding the analysis of certain medical samples. A portable infrared chemical sensor could be mounted on a drone or carried by users such as doctors, police, border officials and soldiers.

MIT conference seeks solutions for reconstruction in devastated Caribbean
This fall’s record-breaking hurricanes Maria and Irma left a swath of devastation across the Caribbean islands of Puerto Rico, Granada, Dominica, and others. Photos of severely damaged or demolished houses, and statistics about the scale of the destruction and the slow pace of recovery efforts, reveal a tragic level of suffering in an already economically ravaged region. Two-day workshop featuring island leaders explores ways to rebuilt better, more resilient infrastructure.

Effects of climate change could accelerate by mid-century
Environmental models used in a new study are showing that the effects of climate change could be much stronger by the middle of the twenty-first century, and a number of ecosystem and weather conditions could consistently decline even more in the future. If carbon dioxide emissions continue at the current rate, they report that scenarios of future conditions could not only lead to a significant decrease in snow days, but also an increase in the number of summer days over 90 degrees and a drastic decline in stream habitat with 40 percent not suitable for cold water fish.

DNA has gone digital – what could possibly go wrong?
Biology is becoming increasingly digitized. Researchers like us use computers to analyze DNA, operate lab equipment and store genetic information. But new capabilities also mean new risks – and biologists remain largely unaware of the potential vulnerabilities that come with digitizing biotechnology. In 2010, a nuclear plant in Iran experienced mysterious equipment failures which paralyzed Iran’s nuclear weapons program. Months later, a security firm was called in to troubleshoot an apparently unrelated problem, and found a malicious computer virus called Stuxnet, which was telling uranium-enrichment centrifuges to vibrate. Stuxnet demonstrated that cybersecurity breaches can cause physical damages. What if those damages had biological consequences? Could bioterrorists target government laboratories studying infectious diseases? What about pharmaceutical companies producing lifesaving drugs? As life scientists become more reliant on digital workflows, the chances are likely rising. The emerging field of cyberbiosecurity explores the whole new category of risks that come with the increased use of computers in the life sciences.

The odds of a megadrought in western, southwestern U.S.
In the southwestern United States, water management is a top concern. If a megadrought occurs, large-scale water management decisions affecting millions of Americans must be made to protect agriculture, the ecosystem and potable water systems. Understanding the odds of a widespread megadrought becomes important for planning purposes. To help untangle fact from speculation, climate scientists have developed a “robust null hypothesis” to assess the odds of a megadrought – one that lasts more than thirty years – occurring in the western and southwestern United States.

High-resolution climate models offer alarming new projections for U.S.
Approaching the second half of the century, the United States is likely to experience increases in the number of days with extreme heat, the frequency and duration of heat waves, and the length of the growing season. In response, it is anticipated that societal, agricultural and ecological needs will increase the demand on already-strained natural resources like water and energy.

Using smartphones — instead of body parts — for identification to deter cybercrime
Not comfortable with Face ID and other biometrics? This cybersecurity advancement may be for you. Researchers have discovered how to identify smartphones by examining just one photo taken by the device. The advancement opens the possibility of using smartphones — instead of body parts — as a form of identification to deter cybercrime.

Reusable sponge soaks up oil, revolutionizing oil spill and diesel cleanup
When the Deepwater Horizon drilling pipe blew out seven years ago, beginning the worst oil spill in U.S. history, those in charge of the recovery discovered a new wrinkle: the millions of gallons of oil bubbling from the sea floor weren’t all collecting on the surface where it could be skimmed or burned. Some of it was forming a plume and drifting through the ocean under the surface. Scientists have invented a new foam, called Oleo Sponge, that addresses this problem.

Gulf Coast universities team up to address hurricane resilience
A new multi-institution research center will focus on helping the Gulf coast do better at preparing for and mitigating the damage and loss of lives from hurricanes and other severe storms. The Hurricane Resilience Research Institute (HuRRI) draws upon the strengths of its seven participating universities, from flood mitigation and hurricane modeling to public policy.

2016 extreme weather events tied to climate change
According to a new research report, the 2016 global average temperature and extreme heat wave over Asia occurred due to continued long-term climate change. Additionally, climate change was found to have influenced other heat events in 2016, including the extreme heat in the Arctic, development of marine heat waves off Alaska and Australia, as well as the severity of the 2015-2016 El Nino, and the duration of coral bleaching in the Great Barrier Reef.

Bolstering cybersecurity in harsh environments
According to the U.S. Federal Bureau of Investigation, the financial loss from cybercrime in the U.S. was over $1.3 billion in 2016. As this number is only expected to rise in the upcoming years, the military, businesses and individuals are seeking new ways to guard their information. Physical unclonable function (PUF) devices hold promise.

“Hacking for Defense” class an example of Stanford’s relationship with the U.S. military
Alongside all the tech companies and consulting firms present at career fairs, Stanford students looking for employment are likely to encounter another major industry when talking to recruiters: the defense sector. Although anti-war activism in the Vietnam era severed many of the university’s ties with the U.S. military, the relationship between the two has seen a revival over the years, and national security and defense institutions are more visible on campus now than they were just a decade ago. A relatively new class, MS&E 297, adds yet another wrinkle to that ongoing narrative – and one that not everyone is happy about.

Climate change made Hurricane Harvey's rainfall three times more likely
Climate change did not cause Hurricane Harvey, but two independent studies have concluded that global warming dramatically increased the probability of a storm of its magnitude occurring ahead of its appearance, and intensified the severity of its impact when it arrived.

Effective counter-messaging strategies to check terrorist recruitment
The Department of Defense has awarded four social science professors $794,000 to research the effects of extremist propaganda on different personality types, as well as the effects of different counter-messaging strategies. The research will answer basic questions about the effects of exposure to online extremist messages and counter-messages, such as: What kind of messaging is most effective? What are the short- and medium-term results of exposure to extremist messages and counter-messages? What personality characteristics in viewers make them more or less receptive to different kinds of messages?
