Flowers tend to stand out against a natural background. A new study shows this contrast evolved in a key relationship with their most famous pollinators – bees.

Kami pertama kali menemukan surat tersebut pada 2019, ketika seorang pembaca membagikannya kepada kami. Di surat ini, Einstein membahas tentang lebah, burung, dan prinsip-prinsip fisika.
Otak lebah madu yang kecil mampu memahami konsep ganjil dan genap, meskipun hanya memiliki 960.000 neuron (dibandingkan dengan 86 miliar pada manusia).
Avec leur cerveau miniature de 960 000 neurones (contre 86 milliards chez l’homme), les abeilles ont réussi à comprendre les concepts d’impairs et de pairs.
Horizontal number lines are often the default option – but our brains may process numbers more quickly in a vertical arrangement.
The miniature brains of honeybees were able to understand the concepts of odd and even, despite only having 960,000 neurons (compared to 86 billion in humans).
Bees watching another bee dance to point out the location of flowers experience a surge of dopamine
Bees have been represented in a range of art forms for millennia, from rock carvings to video games.
Plants use their flower colours for ‘brand recognition’ among insects - but also work together to attract more pollinators.
Bees can perceive flower colours and hues which are invisible to us — such as those produced by reflected ultraviolet radiation.
We first encountered the letter in 2019, when a reader shared it with us. In it, Einstein discusses bees, birds and whether new physics principles could come from studying animal senses.
Waking up to a tuneful melody or favourite song can make us feel more alert than the traditional high-pitched ringing or buzzing of an alarm clock.
Bees may provide surprising insights into the kinds of environments that are best for learning.
Honeybees are good at maths, but it was thought they could only count to four. That is, unless you present them with a task in which they are punished with a bitter-tasting drink for getting it wrong.
Otak lebah madu berisi kurang dari satu juta neuron. Meski begitu, mereka dapat menggunakan simbol untuk belajar matematika dasar termasuk penjumlahan dan pengurangan.
Bee brains contain less than one million neurons. Despite this, new research shows the honeybee can use symbols to perform basic maths, including addition and subtraction.
Estos insectos son un gran modelo para estudiar neurociencia. Un estudio publicado hoy en ‘Science’ muestra que sus capacidades son sorprendentes.
Has your doctor ever taken a photo of your medical condition? It’s really useful to aid diagnosis, but we still don’t have the right legislation to ensure legal and ethical protections.
Extra “eyes” on top of bee heads help them see colours the same way under all light conditions. And it’s an approach that could help us design better cameras.
