The year 2017 saw the second highest global tree cover loss recorded in the history of this planet, according to the World Economic Forum. Researchers at the University of Maryland (USA) found an area of tree loss equal to the size of Bangladesh. That equates to losing 40 soccer fields covered in trees every minute for a year. But guess what, Costa Rica took the fight in the other direction, declaring they had officially doubled their tropical rainforests since 2001. Doubled!

How can the world learn from Costa Rica’s experience and use it as a model for other nations? It helps to take a closer look at exactly what Costa Rica has done right in managing this issue, while other countries have failed miserably. In the mid-20th century, three quarters of Costa Rica was covered in lush, verdant tree canopy. Then came loggers, who savagely cleared acres and acres of pristine rainforest, lining their pockets by selling off Costa Rica’s natural resources. At the same time, of course, they were destroying the natural habitats of Costa Rica’s indigenous creatures, for instance Golden toads and Poison dart frogs.

But then, something changed radically in the thought processes of Costa Rican policy makers, and the rate of deforestation slowed, until it eventually dropped to zero. What happened? Costa Rica awakened to the potential of its rich ecosystems and began vigorously safeguarding them. Healthy ecosystems meant tourist dollars and employment opportunities for Ticos throughout the country.

A little bit of norovirus—the highly infectious microbe that causes about 20 million cases of food poisoning in the United States each year—goes a long way. Just 10 particles of the virus can cause illness in humans. A team of University of Arizona researchers has created a simple, portable and inexpensive method for detecting extremely low levels of norovirus.

Jeong-Yeol Yoon, a researcher in the Department of Biomedical Engineering; Soo Chung, a biosystems engineering doctoral student who works in Yoon’s Biosensors Lab; and Kelly A. Reynolds, Chair of the Department of Community, Environment and Policy in the Mel & Enid Zuckerman College of Public Health, led the project. The team published their results in ACS Omega, the official journal of the American Chemical Society, and Yoon is presenting the research at the ACS Fall 2019 National Meeting & Exposition in San Diego this week.

“Advances in rapid monitoring of human viruses in water are essential for protecting public health,” Reynolds said. “This rapid, low-cost water quality monitoring technology could be a transformational tool for reducing both local and global disease burdens.”

Under his plan, “Justice and Safety for All,” Bernie Sanders wants to ban facial recognition software for policing. As a supporter of Sanders, I’m going to have to respectfully disagree. Here’s why…


Last Sunday, presidential-hopeful Bernie Sanders released on his website what is arguably one of the most extensive plans for law enforcement oversight and criminal justice overhaul that the United States has ever seen. As a progressive, myself, and supporter of Sanders during his primary run, I fully endorse everything that’s been laid out in this plan— that is, except for one minor policy.

The plan, titled “Justice and Safety for All,” calls to “Ban the use of facial recognition software for policing.” It also calls for a “moratorium on the use of the algorithmic risk assessment tools in the criminal justice system until an audit is completed,” whereby the audit would “ensure these tools do not have any implicit biases that lead to unjust or excessive sentences.”

I’m perfectly fine with the policy on algorithmic risk assessment tools being used by our criminal justice system. It’s not a total ban; it simply serves as a temporary safety measure until it’s been proven that these algorithms won’t carry with them any unjust biases. But when it comes to Sanders’ policy on banning facial recognition software for policing, I simply cannot get behind it.

Today the U.S. Food and Drug Administration announced a comprehensive policy framework for the development and oversight of regenerative medicine products, including novel cellular therapies.

The framework — outlined in a suite of four guidance documents — builds upon the FDA’s existing risk-based regulatory approach to more clearly describe what products are regulated as drugs, devices, and/or biological products. Further, two of the guidance documents propose an efficient, science-based process for helping to ensure the safety and effectiveness of these therapies, while supporting development in this area. The suite of guidance documents also defines a risk-based framework for how the FDA intends to focus its enforcement actions against those products that raise potential significant safety concerns. This modern framework is intended to balance the agency’s commitment to safety with mechanisms to drive further advances in regenerative medicine so innovators can bring new, effective therapies to patients as quickly and safely as possible. The policy also delivers on important provisions of the 21st Century Cures Act.

We’re at the beginning of a paradigm change in medicine with the promise of being able to facilitate regeneration of parts of the human body, where cells and tissues can be engineered to grow healthy, functional organs to replace diseased ones; new genes can be introduced into the body to combat disease; and adult stem cells can generate replacements for cells that are lost to injury or disease. This is no longer the stuff of science fiction. This is the practical promise of modern applications of regenerative medicine.

It will take more than six weeks to travel about 238,600 miles (384,000km) to the moon. The four-tonne spacecraft has a lunar orbiter, a lander named Vikram after the founder of Isro, and a rover. The rover, named Pragyan, which means “wisdom” in Sanskrit, will spend two weeks traversing the moon’s surface. The six-wheeled vehicle, which will be deployed in early September, will collect crucial information about the mineral and chemical composition of the lunar surface, and search for water.


It was, he added, a “fully indigenous” project, using Indian technology.

Chandrayaan-2 aims to become the first mission to conduct a surface landing on the lunar south pole region, where it will collect crucial information about the moon’s composition. It would be India’s first surface landing on the moon – a feat previously achieved by only Russia, the US and China.

The $141m (£113m) mission is a “demonstration of the growing sophistication of India’s space power”, said Dr Rajeswari Pillai Rajagopalan, head of the nuclear and space policy initiative at the Observer Research Foundation thinktank in Delhi.

The procedures implement national-level and DOD policies to protect information from foreign intelligence collection. It requires that the application of TEMPEST countermeasures be proportional and appropriate to the threat and potential damage to national security. It explains the selection, training, utilization, and operational requirements for appointment of an Army certified TEMPEST Technical Authority (CTTA) and provides Army protected distribution policy.
