Lilacs are a low-maintenance shrub that are grown for their longevity, ease of care, privacy screening and abundance of full springtime blossoms. Though “lilac” brings to mind a light purple color, the lilac flower comes in many shades from white to dark purple and even magenta. No matter the color of the flower, the scent remains the same: soft, romantic and nostalgic. It’s no wonder lilac is one of the most popular scents in perfume, candles and skin-care products. If you have access to fresh lilac flowers, you can easily capture some of their short-lived springtime fragrance for yourself.
The insects secrete invisible markers when they touch their feet on a surface, which can be detected by themselves and other bumblebees.
Researchers from the University of Bristol, in the UK, found that bees can distinguish between their own scent, the scent of a relative and that of a stranger.
This ability can be used to improve their success at finding good sources of food and avoiding flowers that have already been visited and mined of nutrients.
“Bumblebees secrete a substance whenever they touch their feet to a surface, much like us leaving fingerprints on whatever we touch,” says the lead author, Richard Pearce. “Marks of this invisible substance can be detected by themselves and other bumblebees, and are referred to as scent-marks.”
“We performed three separate experiments with bumblebees, where they were repeatedly exposed to rewarding and unrewarding flowers simultaneously that had footprints from different bees attached to them.”
In the study, each flower type carried scent-marks from bumblebees – either from them, sisters from their nest or strangers from another nest – or were unmarked.
The bees were able to distinguish between these four flower types, showing that bees can tell marks of their own nests from strangers but also can discriminate between the smell of their own footprints and those of their nest mate sisters.
“This is the first time it has been shown that bumblebees can tell the difference between their scent and the scent of their family members,” Pearce says. “This ability could help them to remember which flowers they have visited recently.”
“Bumblebees are flexible learners and, as we have discovered, can detect whether or not it is they or a different bumblebee that has visited a flower recently,” he says. “These impressive abilities allow them to be cleverer in their search for food, which will help them to be more successful.”
The COVID-19 pandemic has forever changed the face of America’s workplace. In fact, an increasing number of folks might find their “new office” feels a lot like home — because it is literally their home.Our post-pandemic “return to the office” may look very different with hybrid or fully remote work models rapidly rising in popularity. Studies support this trend with 83% of workers believing a hybrid model would be optimal going forward, according to an Accenture survey. Further, 87% of managers believe working from home is the future, according to Remote-How research.While the new dynamic promises an improved work-life balance, it will also cause energy use and utility bills to skyrocket with technologies, appliances and systems running overtime at unprecedented levels — making optimal, energy-efficient home climate control a greater challenge.The good news is that families can prevent a utility-bill blitz by following a few simple tips. With home heating and cooling accounting for nearly half of home energy use, small steps can go a long way.
* Ease Into Electric: According to Columbia University’s Earth Institute, electric systems are a solution to decarbonize home climate control. Among the most energy-efficient heating and cooling products, electricity-powered ductless mini-split systems, offered by companies including Fujitsu General America, can save as much as 25% on your energy bill. Mini-splits use thin copper tubing to pump refrigerant from an outdoor compressor directly into an indoor air-handling unit, where the air is quietly distributed to the interior space.
* Get “Smart” About Climate Control: When it comes to smart home temperature control, there are Smart HVAC Systems and Smart Thermostats. Smart HVAC systems have built-in Internet capability and can be controlled directly without additional equipment. Smart Home Thermostats create “smart” systems by enabling remote temperature control via a mobile or Internet-connected device or voice-operated home automation system.* Voice Your Preference: Take control of your comfort. Most HVAC manufacturers offer apps that enable systems to be controlled from anywhere using a mobile device. Voice-control capability uses digital assistants, such as Amazon Alexa or Google Home, to verbally dictate home temperatures. Easily controlling the temperature more closely allows homeowners to be more comfortable and improve energy savings.* Find Your Efficient Comfort Zone: Many of us live in homes designed for bigger families, but have yet to downsize. If you find yourself using a fraction of your home on a regular basis, consider upgrading to a zoned ducted, or ductless system. That will allow you to save energy heating and cooling spaces where you and your family don’t spend a lot of time. This will multiply savings as you’re not only needing less cooling, but you also gain from a more efficient system in the spaces you do still use.* Try Low-tech Fixes: Simple changes can have a big impact. Take advantage of the sun’s energy to heat your home by opening your south-facing curtains at sunrise to make best use of “passive solar gain.” Force down warm air. Denser, cooler air stays closer to the ground, and warmer air rises. So, force it downwards with a low-speed fan. Insulate and fill the gaps. Warmed air leaking out around poorly sealed window frames, power sockets, recessed light fittings, and other gaps is a big source of heat loss in homes. And thick curtains help to insulate glass at windows.If your family is spending a lot more time at home and your utility bills are soaring, a ductless heating and cooling system is definitely a worthwhile investment. Many Fujitsu systems have an Energy Star rating that is more than twice as efficient as the minimum standard set by the government.
