Light Pollution at Night Disrupts Ecosystem, Says Study. VOA

Increased exposure to artificial or outdoor light, referred to as light pollution, at night not only raises health concerns for humans but can also significantly harm the entire ecosystem, says a new study.

The study showed that light at night affects species’ composition as well as their food chain length.


“Night-time light is having profound impacts that extend to the entire ecosystem,” said Mazeika Sullivan, Associate Professor from the Ohio State University in the US.

Artificial light is a pollutant, changing the natural course of life for people, animals and plants.

“We are experiencing this pollution that we do not think about, but it is all around us and it is chronic and it is happening everywhere. It is also unprecedented in earth’s history,” Sullivan added.

For the study, the team examined the effect of existing artificial light in streams and they manipulated the light in wetlands.

From those areas, they collected a variety of water-dwelling and land-dwelling invertebrate species, including mayflies, water bugs, ants and spiders.

Findings, published in the journal of Ecological Applications, demonstrated that species’ composition changed with an increase in light intensity.

They also discovered that the food chain length of the invertebrate communities shortened with more light, indicating that the ecosystem is less complex.

“Decreases in food chain length are a pretty big deal as it reflects not just changes in the architecture of an ecosystem — the numbers of various species — but also shifts in ecosystem stability and nutrient flows,” said Sullivan.

In addition, invertebrates became less reliant on food sources that originate in the water when they were exposed to moderate light levels, results showed.

Interventions such as carefully directing light, using motion sensors to activate lights only when they are needed and dimming them when human activity is minimal could all have the potential to lessen the effects of lighting near wildlife, the study noted. (IANS)

Union Finance Minister Nirmala Sitharaman on Saturday asked the Directorate of Revenue Intelligence (DRI) to prevent dumping of toxic wastes in India.

Union Finance Minister Nirmala Sitharaman on Saturday asked the Directorate of Revenue Intelligence (DRI) to prevent dumping of toxic wastes in India. Speaking at an event to celebrate DRI's 64th foundation day, Sitharaman lauded DRI's compact strength of about 800 officers for their relentless efforts despite the imminent risks. The Finance Minister stated that the officers may be keeping a low profile, but they are acting like the frontline defence forces, doing spectacular work in safeguarding the economic frontiers of the country. "The recent smuggling attempts of huge quantities of narcotics, gold, red sanders, ivory, cigarettes etc. unearthed by DRI were appreciated by the Finance Minister," the Ministry of Finance said in a statement.

"Sitharaman said that the message through such enforcement actions should be such that these acts of brazen attempts at smuggling are nipped in the bud," the statement added. The Finance Minister also said that better coordination among the law enforcement and intelligence gathering agencies and sharing of actionable intelligence are the way forward in protecting the frontiers of the country more efficiently. "Sitharaman also asked the DRI to focus on interdicting dual use technology items as well as preventing the dumping of toxic wastes in our country," the statement said. (IANS/ MBI)

Tech giant Amazon has expanded the sound detection capabilities of Alexa along with more features.

Tech giant Amazon has expanded the sound detection capabilities of Alexa along with more features. Alexa can now identify the sounds of running water and appliances beeping, reports Android Central. This means users can set up an Alexa routine to notify themselves when the washer beeps to indicate that laundry is finished, the report said.

When Alexa detects that the faucet has been left open, it will send users a notification as well so they can take appropriate action, it added. Amazon previously said at its event in September that it would add the ability to programme Alexa to recognise custom sounds, but that feature has yet to arrive. Having said that, the two new sound detection capabilities not only help users save energy, but they also make it easier to avoid paying for unnecessary charges on your home utilities, the report said.

The retail giant has also announced ultrasound motion detection, which will allow you to set up "Occupancy Routines" on additional Echo devices. This feature allows your smart speaker to detect nearby motion and initiate a routine, such as turning on the lights. It is compatible with many of the best Alexa speakers including the 4th-gen Echo, Echo Dot and Echo Dot with Clock. (IANS/ MBI)
